Jeepyjay Diary

Catching Up

2012-01-22T22:23:00.003Z

I seem to have lost the motivation to keep this diary up to date lately.

Before christmas I invested in a new computer, a Samsung laptop with Windows 7 and considerably more power than my previous desk top tower type, and I've now just about got it all working, transferred all the files from my old machine, and reinstalled the key programs that I use. Now I should be able to catch up on all the updating work on my website, and on the Hastings chessclub site, that I have in mind.

Over the new year I played in the Hastings chess congress, just in the lower sections, and didn't do particularly well, but I'm hoping my grade may have improved slightly. I seem to be getting better at prosecuting an attack once I have obtained an advantage, particularly using queen and knight together.

Today (Sunday) I went to London by train, to attend the 11 am lecture by Kenan Malik at Conway Hall. The subject was "The Myths of Christian Europe". I thought it might provide me with some material for my own talk to Hastings Humanists on 9 February, which is on the rewriting of history by christian apologists.

I also stayed for a symposium held at 2.30 pm on the future of South Place Ethical Society, of which I am a member. It seems some members fear a "take-over" by the BHA, but personally I can see no harm in greater cooperation between the two organisations. I would also like to see the Rationalist Association involved. Some of the members there seem to hold strange ideas about what "Humanism" is.

Going to the first meeting meant getting up very early since there were works on the line and a bus service between Wadhurst and Tonbridge. The train left at 7.38 and I arrived at Charing Cross about 10.15. The return journey was longer due to waiting for the connecting bus and train. The "bus" was in fact a very long "Eurocruiser" coach which had considerable difficulty negotiating some of the sharp bends on the side roads and station entrances.

Mathematics and Number Wisdom

2011-12-17T16:19:00.003Z

I've at last got round to updating the mathematics section of my website. The "Rational Mathematics", "Alternative Mathematics" and "Geometry" sections are now all under one index page. I've also transferred the pages on "Altairian Arithmetic", "Numerology" and "Numeromancy" from Esoterica to the Alternative Mathematics section, together with a new page on "Arithmosophy".

I'm not sure that Numeromancy and Arithmosophy can really be called Mathematics but they use numbers and require a knowledge of some arithmetic. I base my interpretation of "Wisdom of Numbers" on multiplicative relationships rather than additive properties. This makes it a more disciplined realm.

I have masses of notes on Geometry, but lack of satisfactory software for producing diagrams has held it back. There is nothing particularly new, just improved arrangement and presentation, making use of CSS.

A Bright Morning's Walk

2011-12-12T15:37:00.003Z

I seem to have been neglecting this Diary. The last message I intended to post here, about seeing a rainbow at London Bridge, went to the Hastings Humanists blog by mistake.

It was a beautiful sunny day this morning, so I took a walk along the front as far as Glyne Gap to see how the new cycle path is progressing, and there is stil quite a lot of work to be done, but when finished it will be possible to cycle to Bexhill without going on a main road at all.

I went to the Ravenside retail park to have a look at the computers on display in PCWorld and ended up buying one. It's a large Samsung laptop, which I'm hoping will be able to replace the old desk-top machine on which I'm typing this message.

I left about 10 am and got back about 2 pm. There was quite a cold wind, whipping up surf on the sea, which was near to high tide, but the sky was blue like a spring day, and the birds were singing. But soon after I got back the sky darkened and the rain came down. It's just started again now as I write.

Last month, after my visits to Leicester and Bournemouth for the chess, I had some trouble with my right leg and had to rest it, but it seems to have held up today, but maybe a bit stiff in the morning, well see. I needed the exercise anyway.

Words

2011-10-22T19:42:00.003+01:00

A day or two ago I finally got round to updating the Words section of my website. There is not much difference really except in the presentation, which now makes use of CSS (Cascading Style Sheets) to ensure the pages are in a consistent style throughout. There is a lot more to CSS that I need to learn, I've only used the basics to determine the background colours, typefaces, margin settings and suchlike.

In the simplified spelling I've gone back closer to the orignal 1997 article, though with j used for the th sound in 'then' and q for the indefinite vowel. The only new feature is the use of th for the tch sound in 'match' and dh for the dge sound in 'hedge', which I consider an analogous use of h as for sh in 'fish' and in the combination zh often used for the sound in 'leisure'. It always seems to me that there must be another little tweak somewhere that will make the system better, but when I try it there is usually some unforeseen problem. I'll probably come back to the question in another three years.

The z-section, which used to contain the verse anthologies, is now devoted to lists of links, and the s-section whch contained the stories is no more. Instead they are all in the w for Words section.

Bournemouth Weekend

2011-10-21T23:07:00.003+01:00

Around the 7th October I got the idea into my head that I should play some more chess and enter the Bournemouth Congress which was on the next weekend 14 to 16 October. Thanks to the internet and email I managed to send an entry form, book a bed and breakfast for two nights and work out a railway journey, along the south coast, changing at Brighton and Southampton Central.

The travelling went very well apart from getting a slow train from Southampton and having to change again at Brockenhurst, to catch the Cross-Country train from Manchester that I should probably have caught in the first place.

This was the first time I'd been in Bournemouth since the memorable BCPS weekend there in 1989. The weather was excellent and I did a lot of walking around the central areas of the town; probably too much as by the end I was struggling to get up the hill to the venue with a stiff right knee.

My results were as poor as at Leicester, winning only the last game, and that only because my opponent blundered away a rook, and refused to agree a draw, which I thought would have been fairer, since he had played well and had the advantage up to that point. There are photos of the event here.

Since I got back on the Sunday night I've been feeling pretty tired and have endeavoured to take it easy and rest my brain and my leg. The photo is of a tethered balloon on which people were booking rides in the Winter Gardens.

Weekend in Leicester

2011-10-07T11:36:00.003+01:00

I spent the weekend from Thursday 29 September to Monday 2 October in Leicester, playing in the Chess Congress and attending meetings at Secular Hall. The weather was very hot and sunny, not what I had expected for this time of year, and not ideal for playing chess. However I suppose I can't really blame the weather for my poor results, just two draws (in the first and fifth games) and one of those was against a junior.

At Secular Hall there was a lecture on 29 September about the situation in Libya, though the speaker was a supported of the Gaddaffi regime, who described his 40-year rule as a type of socialist utopia! What is going to happen there in future is of course difficult to predict. On Sunday there was a meeting of a new History Group in the afternoon, and in the evening a most interesting talk on Thomas Babbington and his friends and family and their work for the abolition of the Slave Trade. They did a lot of the work in preparing evidence for William Wilberforce to use in his speeches in Parliament (from which Quakers and nonconformists were excluded).

I travelled to London by train, and to Leicester by coach. On the return journey, also by coach from Leicester I thought I would try the coach to Hastings. This proved to be a mistake, as the so-called 'Express' took nearly 4 hours! It began by going south-west to Mitcham, and so on to Coulsdon and East Grinstead. Then it went on a grand round tour of East Sussex, stopping at Uckfield, Hailsham, Eastbourne, Pevensey, Bexhill and other places.

Allotting Computer Time

2011-09-17T21:21:00.005+01:00

Sorry I've not found time to post anything here for several weeks. Most of my time on the computer has been taken up either with Twitter or trying to improve my understanding of CSS (Cascading Style Sheets) so that I can improve my website and also help to improve the Hastings Chess Club's website. If you click on the "Events" link you will be taken to a page I've designed, and you will find another if you click on the link to the page abour Jude Lenier's simultaneous chess display. I would like feedback to know how this style is perceived, whether the rest of the site should be updated similarly, and if anyone can offer suggestions for improvements. I've also done a lot of work on sections of my own website, but the pages can only be posted to the site when they are all ready, because they all link together, so there is nothing new to see there yet.

The Birds!

2011-08-25T20:33:00.003+01:00

This photo is taken from the window that faces the opposite direction to the previous photo. The local pigeons are usualy flying about in disordered groups. However on this occasion I noticed that they all lined up with miltary precision along the roof ridges of the Holy Child college (formerly a convent), and stayed there quite still for a longish time. I wondered which is the general: the one on the point of the gable, or the one on the head of the christ child? (You may need to click on the photo and look at the larger version to see it clearly).

The local pigeons are of very varied colours, a few white, a few black, and quite a number an attractive brown. On the old RDFRS forum I queried why this might be, when the common pigeons seen in Warrior Square are more uniformly the traditional blue-grey, and seagulls have no noticeable variation. I was informed that this must be due to human intervention. Perhaps by the nuns who used to live there breeding and selecting them.

The Eyes in the Sky!

2011-08-24T20:58:00.003+01:00

I've been intending to post this photo since the day after I posted the last message. I was half-dozing in my chair in the afternoon and suddenly woke up to see what appeared to be two demonic eyes glaring at me through the narrow window opposite. By the time I had realised what it was and got my camera ready the cloud formation, with the sun behind it, had moved on slightly, but the two "eyes" are still visible, but not so dramatic as they looked a minute or so before. Also the view shown is much wider than the one I saw framed by the window. One can appreciate from such an experience how people can attribute such phenomena to the actions of supernatural beings, and perhaps interpret them as personal warnings, since they depend on the location of the viewer and would not be seen much more widely.

The Two Ritas

2011-07-19T19:51:00.005+01:00

This morning around mid-day I felt in need of some exercise, and it was a sunny day, possibly the last for a while, so I decided on a walk along the prom towards West St Leonards and perhaps a meal out. On the promenade near the Azur restaurant I was stopped by two ladies, who turned out to be Jehovah's Witnesses. I'd met at least one of them before, having argued with her at the door of my home, and she remembered me as being a Humanist. We exchanged names and some banter. She was Rita, and so was her companion.

I carried on with my constitutional, which Rita had called "power-walking", as far as the end of the cycle-path. No sign yet of it being extended to Bexhill. Turning back there I noticed that the "Bridge Cafe" on the corner was open, so went in for a late breakfast and cup of tea. I didn't remember it being open on other times I've walked past, but apparently the people who run it have been there for ten years. While I was there a group of eight businessmen came in, though there's not much sign of business around there now, since the wood-store closed down.

Maybe I ate my sausage, egg, bacon, beans and tomatoes too quickly, or didn't rest long enough to let them digest, because as soon as I got back home I began to have a bout of hiccups. Once it starts I find it difficult to stop. After a rest it seems to stop, but as soon as I make some strenuous move it starts up again. I think I will call it a bout of "The Two Ritas" in future!

Digging, Hacking and Tweeting

2011-07-14T12:56:00.004+01:00

On Tuesday morning I finally got round to weeding and digging over the little strip of front garden I have. The next day I felt very stiff, no doubt due to using unaccustomed muscles. There was a forecast of rain for the afternoon, and I was thinking of sowing some grass seed, but the rain never came, and it has remained dry since. I suspect if I sowed the grass seed in the dry ground the pigeons would soon have it, so I'll wait for some rain.

Yesterday I had an email fron Vodafone saying they were sending me a SIM card. This was odd since I've never had any dealings with them. I deleted it as spam. Today I received the SIM card. It says "We're delighted to enclose your free SIM card and details of the Vodafone TopUp and Get International Freebee you selected." But I've never "selected" any such thing. I have an old pay-as-you-go mobile phone that I got from Virgin but have not used for over a year, and have no intention of reviving. I did think of emailing Vodafone, but their website wasn't very helpful and came with lots of warnings and popups, so I think it best to just ignore it.

My twitter account was apparently hacked a few days ago, and a message under my name was sent to a number of my "followers". Originally the message came from someone I follow and said "is it you in this photo" I clicked on this thinking it might refer to the photo of me with Ken Ham taken in Leicester in 2006 that was published on the Answers in Genesis site. However the link just led back to the twitter log-in site. I changed the password on my account, and the problem has not recurred, but it seems this sort of annoyance must be very easy to do.

I've now sent over a hundred tweets and have over 30 followers, though a number of them just seem to be local businesses in St Leonards that are no doubt angling for my trade. The most useful contacts I have made are with mathematicians who have provided a lot of interesting links, to websites and PDFs. I also had an amusing exchange with Bob Churchill, formerly of the BHA, about the type face "Comic Sans" which I use for the navigation links on the Mayhematics site, but he doesn't like. He wrote that we must be "aesthetically incommensurable", to which I replied that that must mean I'm rational while he is irrational (a mathematical joke for those not in the know).

Light Music Festival

2011-07-01T23:04:00.003+01:00

I've been following the series of programmes on Radio 3 in the BBC's "Light Fantastic" music festival over the past week, since I enjoy this type of music, at least when it is well done.

An article by Stephen Hough in the Telegraph on line praises light music and has some links to several classics.

On the Sunday however I went to the concert put on by the Cory Band at the Queen Elizabeth Hall and, although I stood it all through to the end, found it extremely disagreeable simply because of the sheer loudness. Their only interpretation of forte was as fortissisimo. Maybe on a bandstand in the open air the sound dissipates, but at the back of the hall it was unpleasant.

Some pieces I've not heard for years, and have not so far heard on the programmes are "Parade of the Tin Soldiers" by Leon Jessel and "Do Not Forsake Me" (from the film "High Noon") by Dmitri Tiomkin; but I suppose these don't count as British Light Music. Another is the Oxford Street march by Eric Coates, although I have a CD with an old recording of this; I found the tune running through my head earlier today, and had to check that's what it was.

Website Upgrade

2011-06-19T12:05:00.003+01:00

Yesterday my mayhematics website was unavailable due to the bandwidth limit being exceeded. This appears to be due to more people looking at it and downloading pages from it. There was a big spike at 4pm on Saturday for some reason. So I have had to upgrade to the next level, which about doubles the price to be paid each year to £60, which still seems very reasonable. At any rate I hope this resolves the problem. Perhaps I should look into ways of charging for donwloads.

I'm also thinking of registering some other domain names, since the subjects covered on the site do not all fall logically under the "mayhematics" heading, they have all accumulated in one place due to previous service providers closing down or not continuing to provide support, and due to changes from dial-up, to cable broadband, to telephone-line broadband connections.

Probably it is about time to upgrade my computer as well, but I dread all the problems that that could throw up so will probably leave it to the last minute as usual when it will be unavoidable.

Coughs and Wheezes

2011-05-29T09:23:00.002+01:00

I've had a touch of flu for several days, probably exacerbated by standing around in the cold on London Bridge station platforms last Monday. It's been making it difficult to get any sleep, since for some reason I start coughing whenever I lie down and try to relax. When it gets bad, the cough seems to go through my vocal chords so that it makes a mad laughing noise rather than a wheeze. I tried a packet of lemsip but it didn't seem to do any good. A mint toffee is effective for a while. Fortunately it now seems to be clearing up. I must get back to taking more regular exercise, haven't been swimming so far this year.

Rationalism Advances

2011-05-24T10:37:00.005+01:00

I took this photo at the AGM of the Rationalist Association, held on Monday evening in the Great Hall of the Art Workers Guild in Queens Square, London. This is a place I've not been to before. The bust above the big chair is of William Morris. In the middle Jim Herrick is talking to Caspar Melville (CEO of the RA, and Editor of New Humanist) and Laurie Taylor (Chairman). It seems the RA and New Humanist is making a determined move to be more active in promoting debates and vastly increasing circulation of the magazine. I asked whether this might mean some "dumbing down" of the content - not that I'm against this, I might be able to understand more of it!

Ceremonials

2011-05-22T12:03:00.003+01:00

On Wednesday 18th May I went along to the White Rock Theatre to attend the Mayor-Making ceremony (the present Mayor was re-elected) and presentation of the Freedom of Hastings to former MP Michael Foster. Having to keep on "be upstanding" every time the mayor entered or exited was a bit wearing. It was curious to note that the conservative councillors still observe the ceremonial aspects by wearing reddish-coloured robes, while the labour side were in normal dress. The "processing" in and out could well also be done away with. The best part of the show were the performances by children from local schools, though one of the songs was mildly religious. The dance by the older girls was apparently to celebrate the suffragettes.

On Saturday 21st May I accepted an invitation to attend a meeting of the Freemasons Lodge formed by Old Olavians from my former school. This was held at the Freemasons Hall in Great Queen Sreet in London. This is a very large building, in art deco style, built as a memorial after the first world war. We were admitted to the so-called "Indian Temple" which is apparently only one of the smaller temples in the building, and treated to a talk by one of the Masters. The temple was a large rectangular room with domed roof. The masons in their ceremonial aprons sat on thrones, three at each end, and one in the middle of each side, with lighted candles in front of them.

According to the talk the masons are now purely a philanthropic organisation, raising money for work done by other charities like the red cross, or to supply equipment to local hospitals, although they also provide relief for old masons fallen on hard times. However they require applicants to declare belief in a "supreme being" to become a member, and swear their oaths on a bible, which rules me out. Though doesn't this now contravene discrimination laws, if they are not an explicitly religious organisation?

I'm afraid I found their costumes and their "processing" only rather comical. They made me think of Tweedledum and Tweedledee, especially as most of the members were of portly proportions. This may be a consequence of their dinners, there was one following the meeting which declined to attend, since it cost £35, a price that represents a whole week of dinners for me.

On Monday I'm due to attend the AGM of the Rationalist Association. I wonder if they go in for robes and ceremonials? I hope not.

Break Building

2011-05-06T15:48:00.006+01:00

I spent most of the Easter and May holiday week-ends watching the snooker world championship from Sheffield, in the hope that newcomer Judd Trump might win over the old guard John Higgins, and he came quite close.

Rather than abolish the May Day holiday break, surely it is time to fix the date of Easter closer to the Spring equinox, in March, so that the two holidays don't come so close. It's getting like Christmas and the New Year.

Much of the rest of my time was spent revising and checking the section on King tours on the Knight's Tour Notes pages, particularly the enumeration of the tours on boards of two ranks. The totals are given by recursion relations and by formulae involving the Fibonacci numbers. This proved quite troublesome, but maybe that's because my brain isn't working a smoothly as it did even a few years ago.

On the 2x8 board there are 128 closed tours, which is easy to verify, but the number of open tour diagrams works out to the surprisingly large, and surprisingly round number T = 32000. I still wonder whether I've got this right, but the other figures seem to be consistent with this. On the same board there are 584 reentrant tours, and G = 8176 geometrically distinct open tours, of which S = 352 are symmetric. These figures are related by G = (T + 2S)/4.

Magic Rook Tours

2011-04-25T10:33:00.004+01:00

The image shows three diagonally magic rook tours that I constructed on 20-21 May 1986 but then seem to have forgotten about. (It was a busy year for me!) The tours have biaxial symmetry and each quarter tour is a bisatin (i.e. uses two cells in each rank and file). If the numbering is shifted by one quarter, so 17 becomes 1, 18 becomes 2 and so on, the rank and file magic property is automatically retained. However for the diagonals to remain magic there must be two numbers less than or equal to 16 in each (i.e. the bisatin has to be diagonal as well). The work was inspired by a less structured diagonally magic rook tour by J. Brugge that appeared in the German chess problem magazine Die Schwalbe in August 1985. Anyone care to enumerate all the diagonal bisatins that could be used?

Tours and Twitters

2011-04-10T18:19:00.004+01:00

I've just been trying to remove two blogs from the list of those that I "follow", but there doesn't seem to be any way to do it. The instructions explain how to do it, and they are supposed to lead to a page where you can click a "stop following this blog" button. But they don't!

A day or so ago I uploaded a new page on King and Queen tours to my Knight's Tour Notes pages on the Mayhematics site. This is a page that has been waiting to be uploaded to the old KTN site for several years. There's stil a lot of other material, and updates to existing material, to be added. It's a continuous process.

I've been getting more involved with Twitter. I now have about 15 followers, have sent about 30 tweets and follow about 70 people and organisations. Mostly these are to do with mathematical recreations and humanism. One message led me to this site on mathematics by John D. Cook where the old subject of the misattribution of Beverley's magic tour to Euler came up, and I've contributed to the discussion.

Honeycomb Tours

2011-04-07T09:26:00.005+01:00

I have added a new page about tours of Honeycomb Boards to the Knight's Tour Notes pages. This collage shows a selection of results. Some date back to 1974 when I sent an example tour to W. Glinski whose Hexagonal Chess on a 91-cell board was popular. Others are new results. I've included wazir, king and knight tours that show various different types of symmetry.

A Disorienting Day

2011-03-26T22:45:00.003Z

There was a concert of light music, of which I am a fan, due to be held at St George's Church in Beckenham this evening. So I thought I would look into the possibility of travelling there by public transport. According to the National Rail Enquiries website, which I've found to be reliable previously there was a train at 4:55 that would get me to Beckenham Junction by 17:15 with one change at East Croydon.

However, when I tried to buy such a ticket at Hastings station I was told such a trip was "impossible"! Also that the National Rail Enquiries were now run by a bus company who didn't understand the railways. Apparently the link from East Croydon to Beckenham Junction is via a Tram line. This appears to be correct: it is on something called the London Tramlink, which I've never heard of before, though it has been around for ten years.

So, lacking a clear route, I aborted the trip and decided to listen to a concert on Classic FM. This was a Prokofiev concert introduced by Howard Goodall. The first item announced was his Classical Symphony, number 1. However the music played bore little resemblance to previous performances of that work I had heard. I suspect it was some other of his symphonies, in far more modern style. The second item was announced as the music from Romeo and Juliet, including the "Dance of the Knights". However, unless I fell asleep, this was not the music played.

Tomorrow apparently it's time to put the clocks back, or is it forward? I'm not sure if I'm coming or going.

A Magic Knight Rectangle

2011-03-08T08:02:00.004Z

Back in 2003 I was able to prove that magic knight's tours were not possible on boards 4n+2 by 4m+2, but a proof for the 4n by 4m+2 case eluded me. I now see that that is because there is no such proof! Thanks to a suggestion by John Beasley, that since there is a simple magic knight+wazir tour on the 2x4 board, a magic knight tour should be possible on a sufficiently large 4n by 4m+2 board, I looked at the subject again and found two 12x14 examples last night, of which this is the first:

141 122 143 038 139 124 127 042 045 030 131 026 047 028
144 037 140 123 128 039 044 125 130 041 046 029 132 025
121 142 035 138 119 126 129 040 043 050 031 134 027 048
036 145 120 063 034 137 014 155 032 135 106 049 024 133
011 064 061 118 013 154 033 136 015 156 051 108 105 158
146 117 012 151 062 059 016 153 110 107 018 157 052 023
065 010 115 060 149 152 111 058 017 020 109 054 159 104
116 147 150 009 114 057 094 075 112 055 160 019 022 053
091 066 007 148 093 074 113 056 095 076 021 162 103 078
006 069 092 073 008 003 082 085 168 161 096 077 100 163
067 090 071 004 083 088 167 002 081 086 165 098 079 102
070 005 068 089 072 001 084 087 166 097 080 101 164 099

It is constructed by the "rolling pin" method that I devised for 12x12 magic tours. It's surprising I hadn't thought of trying this before. It's just a matter of widening the board. The files add to 1014 = 169x6 and the ranks add to 1183 = 169x7. Each file consists of three pairs adding to 127 and three pairs adding to 211. The ranks are made up of pairs of complements adding to 169.

Knight's Tour Notes website gone

2011-02-18T21:21:00.005Z

I've just noticed that my old Knight's Tour Notes website has vanished into the ether. This is not unexpected, since it was housed on a dial-up site which I have been unable to access for several years. I will now have to relaunch it on my Mayhematics site, or start up a new URL. This may take some time. I will probably want to put it into a revised format and improve some of the diagrams.

Outing to London and Leicester

2011-02-15T20:26:00.003Z

On Saturday morning I decided on something of an impulse to combine a trip to London to attend the Conway Hall talk by Jim Moore on "Darwin and the Sin of Slavery", with a trip to Leicester to attend the lecture by Ken MacLeod on "Darwin Dawkins and the Left". This was just about possible in the time by using booking.com to locate a Hotel and the National Rail Enquiries to book the trains, using a debit card and collecting the tickets from the machine at Hastings station. The machine was a bit recalcitrant but finally came up with the tickets.

One of the interesting points from the Moore lecture that I'd not been aware of was the role of Louis Agassiz (now best known for his work on ice ages) in diverting Darwin's efforts into countering Agassiz's strange theory of multiple 'creations' of separate human races known as polygenism.

Ken McLeod's thesis was that many people on the political Left have deliberately misunderstood Richard Dawkins, or the implications of his "Selfish Gene" idea, though it seems to me that many of other persuasions have been equally free in criticising Dawkins without having apparently read his books.

I was hoping also to fit in a Gresham Lecture by Christopher Hogwood, given at the Museum of London at 1pm today (Tuesday). But this was scuppered since my train was over half an hour late arriving at St Pancras, due apparently to signaling problems. It was also raining, so I used my bus pass to get the No.17 to London Bridge, but managed to get there just in time to miss the first Hastings train.

Twittering

2011-02-04T20:35:00.003Z

Well the beard didn't last very long. I'll have to change my photo again. It felt too uncomfortable, and was just as much trouble to maintain as shaving every day or two, as well as making me feel old. Srangely three people complimented me on the beard, but unfortunately after I'd already got rid of it.

I joined Twitter a few days ago. As if I need more ways to waste my time. Somehow I have already acquired five followers and sixteen subjects to follow, and posted two tweets, all this mostly related to humanism.

Nostalgia Apologia

2011-01-22T21:28:00.003Z

I thought I'd let my beard grow during the cold spell over the Winter Solstice, thinking that I would probably shave it off when the weather changed, but it seems I have now become attached to it, at least until any really warm weather should come along. I've also updated my photo here and on facebook accordingly.

This evening, having seen it previewed in the local paper, I went to the White Rock Theatre for an evening of nostalgia, where the Glenn Miller Orchestra was performing. The tunes were good, and some of the individual performers, but it was just far too loud. After the interval I tried moving further back in the Gallery but couldn't escape the sheer blast of sound. It was getting almost painful. So when they started playing something from The Sound of Music, which I certainly don't associate with the Glenn Miller era, I decided I'd had enough.

Queen Victoria in Warrior Square

2011-01-02T20:22:00.005Z

There was a spectacular sunset this evening around 4:30. I went out with my camera to try to capture an image, but by then the view had changed, first the sun came out from behind the clouds, then it quickly set. I got some images, but they were similar to others obtained before. I ended up on the sea-front by Warrior Square and noticed that the statue of Queen Victoria was illuminated with a spotlight and that the plinth seems to have been cleaned. Hence the photo shown here.

I did very poorly in the Weekend Chess Congress, playing in the Minor tournament, since I managed only a draw, and that was against the youngest competitor, where I ended up with a knight and pawn against two knights and pawn. The middle game of the five, played in the evening of the first day, was weird. I made a muddle of the opening and was well down, then somehow revived to fight back to a winning position, and then went to sleep again in the end game and threw it away. Sheer tiredness I think. There are another five games to go in the New Year tournament, which I suspect will be against stronger opposition.

Chess and the Brain

2010-12-31T21:47:00.005Z

I've been playing in the Hastings Christmas Morning and Christmas Afternoon chess tournaments over the last four days, and managed to score 1.5 in each (i.e. one win, one draw and two losses). No prizes for that, but I'm in it just for the practice, since I haven't played orthodox chess for many years.

I'm also entered in the Weekend Congress, and the New Year tournament next week. This is probably too much really. I'm already quite tired. The draws which both went to over 60 moves were particularly wearing. At the end of my last game this afternoon, which I was fortunate to win, I think we were both punch drunk; I'm sure a lot of the moves will make little sense when seen in the light of day.

There was an interesting item on the Today programme yesterday (I think) where it was claimed that Liberals have a developed "Anterior Cingulate(?) Cortex" in the brain, while Conservatives have a stronger "Amigdala(?)" (a primitive, reptilian, part of the brain). It was questioned whether this was from birth or whether the brain differences developed due to experience. I'm hoping my chess exercise will help stop my brain from subsiding into Alzheimers, as it seems to me to show signs of doing.

John Wyndham recalled

2010-12-21T22:57:00.004Z

There was a programme on BBC Radio 4 this morning about John Wyndham, the science fiction writer. I meant to listen to it but as usual got engrossed in something else and forgot. But fortunately it is now possible of course to use Listen Again.

He was a writer I grew up with in the 1950s, and I read all his books, probably from the Public Library, and have returned to them from time to time, and picked up second-hand paperback copies a few years ago, when I joined the Leicester Science Fiction, Fantasy and Horror group, and compiled my Guide to Fantasy Authors and Tales (which I must update some time).

I've always been fascinated by his full name which was John Wyndham Parkes Lucas Beynon Harris, as if he was named after a team of some kind! He used various different combinations of these names for his fiction. His "John Wyndham" style matured after his experiences during the second world war.

In the programme it was mentioned that he called his novels and short stories "Logical fantasies". It seems he was an atheist, since he intended to leave the rights in his royalties to two daughters of a friend or relative, but changed his will when one of them went into a convent as a nun. He also lived in London at something called the Quaker Pen Club, which I'd not heard of before.

I must read The Chrysalids. I seem to have missed that one.

My Chequered Career

2010-12-11T16:59:00.002Z

I've been considerably expanding the pages of My Chequered Career in the Chess Problem section of my website. This is intended to provide a record of my chess problem compositions and the ideas they illustrate. Besides well known pieces like Grasshopper, Nightrider, Leo and Mao, the additional pages also include the other bifurcating hoppers Eagle and Sparrow, and the Clockwork Mouse, as well as variants like Antipodean Chess and Arrow Chess. There are still a lot of compositions to be added. I was hoping this exercise might stimulate me to do some more composing eventually.

Trading Standards

2010-12-06T15:40:00.002Z

I bought a bag of assorted biscuits on Saturday, which had an illustration of chocolate chip cookies and bourbon creams on the cover as well as plainer types. When I opened it however the only chocolate biscuits in it were a few fingers. Almost all the contents was shortcake. There is a disclaimer on the back that says "the assortment may vary ... due to product availability", which must be of dubious legality. The trader was unwilling to give me my £1.49 back and advised me to contact the manufacturers, a company in Rochdale. So I have sent an email to the Tradings Standards office in Eastbourne. The money of course is not important, but there must be a lot of people buying biscuit assortments at this time of year, so there must be quite a bit of profit to be made from such a cheap scam.

Also on the shopping front I've been looking for a waterproof or showerproof jacket, but why are they all so dull? There used to be a road-safety slogan: "Wear something light at night" and white jackets were readily obtainable. Now there is nothing. Maybe depression is the fashionable image, to match the weather and the financial climate.

Winter Gardens

2010-12-03T11:16:00.004Z

This is a photo I took yesterday of Warrior Square Gardens looking out towards the sea and the statue of Queen Victoria. A contrast of tropical plants and arctic weather. The sky was very dull and overcast, but we only got a small further dusting of snow.

I put on my Polish snow boots and ventured out to the nearest Spar store to get some milk for the weekend. They only had a small supply and were out of bread, apart from some "petit pain" apparently baked in the store; no delivery lorries making it down the A21, and I don't think there were any papers, though I wasn't looking for any.

Archiving Websites

2010-11-24T18:11:00.004Z

I've received requests from the British Library to allow my Knight's Tour Notes and Mayhematics websites to be "archived". I think this is a result of requests sent to them by John Beasley with regard to the archiving of the Chess Variants material and the BCVS site.

The address of the archive is: http://www.webarchive.org.uk/ukwa/. I've received emails acknowledging receipt of the online forms that I filled in, but I expect it will be some time before the sites actually appear in the archive. I took the precaution of removing some of the illustrations from the Biographies section of the Mayhematics site, in case they do not meet the copyright requirements.

Five-Directional Knight's Tour Problem

2010-11-08T09:38:00.003Z

It's over a month since I posted a message on this Diary, but since I seem to be the only person to whom it is of any interest that probably won't have been noticed.

The most interesting occurrence of the past month was that one of my correspondents. Harold Cataquet, sent me details of a new knight's tour discovery by Jonathan Welton from Crowthorne, Berks. This can be presented in the form of a puzzle:

To construct a closed knight's tour of the standard chessboard that uses moves in exactly five of the eight possible knight-move directions.

There is just one solution, apart from rotations and reflections. I was able to confirm this by trying to construct a tour. It required only one page of workings on a sheet of squared paper, and involved 21 diagrams though this is far more than is really necessary. I won't publish the answer here, since Mr Welton will probably want it to appear somewhere in print first.

However here is an open-tour solution that I found, starting and finishing on adjacent cells.

17 32 21 28 47 52 45 50
20 29 18 15 22 49 26 53
33 16 31 48 27 46 51 44
30 19 34 23 14 43 54 25
09 38 13 42 55 24 59 04
12 35 10 07 60 03 64 01
39 08 37 56 41 62 05 58
36 11 40 61 06 57 02 63

This was my first attempt at finding a solution on 25 October.

Website Improvement and Expansion

2010-10-03T22:23:00.005+01:00

This week I've been making some major additions and revisions to my mayhematics website. In the first place I have reverted to an older style for the home page, using the rainbow colours to classify the subjects into six sections, and doing away with the three intermediate index pages. I'd really like the six sections, and the centre one, to be circular but square is the best I can do at present.

The next big change is to the Variant Chess section, due to the closure of the BCVS. All 64 back issues of Variant Chess magazine are now available for download from the Variant Chess page. Most of the labour of scanning the magazines, apart from the first eight issues, was done by Peter Fayers to whom thanks are due. At the bottom there is also a link to the list of books and journals which I collected over the years and were part of the BCVS Library, but which I'm now calling the Variant Chess Library. It occupies a bookcase and some boxes in the entrance passage to my flat.

The other change is the addition of a series of pages of short biographies, mainly of radical reformers in the humanist movement, but also including notable scientists and others (there will be many more to add). Some of these were written for the Leicester Secular Society website, and others I had prepared as notes for a series of talks on the History of Humanism. Many have now appeared in shorter form on the Humanist Heritage site maintained by Hamish Macpherson for the BHA.

All in all a very productive week.

Variant Chess: End of an Era

2010-09-26T12:13:00.006+01:00

This Saturday we held the last AMG of the British Chess Variants Society. John Beasley and Peter Fayers came to my flat to settle the final details. So Variant Chess magazine, which I started in 1990, has now also come to an end. The final issue, appropriately number 64, came out in August. Thanks to everyone who has been involved over the 20 years.

Afterwards a small variants tourney was held at Hastings and St Leonards Chess Club. There were five players, so there were five rounds, with the non-playing person in each round choosing the variant for the others to play. The variants chosen were: 1. A game using the back-row sequence BRNKQNRB, 2. Progressive chess, 3. Avalanche chess, 4. Balanced Marseilles chess, 5. Cylinder chess.

The players and their scores were: George Jelliss 0, Bill Penfold 1, Rasa Norinkeviciute 2, John Beasley 3, Patrick Donovan 4. So Patrick won the prize which was a bound set of Chessics magazine. My best game was in the Progressive chess where Rasa had to find a difficult eight-move series to give checkmate. Thanks are particularly due to Mr Penfold for making the effort to master the unfamiliar rules, particularly of the cylinder variant, and to the Club for permitting our use of the venue.

Weekend in Leicester

2010-09-17T19:50:00.004+01:00

On Saturday 11 September I took the train to Charing Cross, walked to Victoria and bought a single National Express coach ticket to Leicester, where I had booked to stay two nights at self-catering apartments by the Grand Union Canal, as illustrated here, although my apartment in fact proved to be on the other side, overlooking the road. The attraction was to revisit my old haunts in Leicester where I lived for nine years, meet some old friends, and to attend the Secular Hall Open Day on the Sunday. (See Hastings Humanists for a brief report).

The idea of buying a single ticket was that I might decide to stay a little longer, but in the event I returned on the Monday. The 11:45 am coach I booked on was about half an hour late, but I wasn't really in any hurry. I sat next to a lady who said nothing, and busied myself mostly with doing the puzzles in the Times. At Victoria Coach Station the lady seemed rather agitated to find her connection on to Portsmouth, and I did my best to direct her, but now feel somewhat guilty that I didn't actually see her to the right bay, or converse with her on the trip.

There didn't seem to be any trains scheduled from Victoria to Hastings so I walked again to Charing Cross. This is quite a pleasant walk, via Buckingham Palace, St James' Park, Admiralty Arch and Trafalgar Square, though I was carrying too much in the form of provisions I had bought, but over-estimated, for self-catering purposes in Leicester. The next day I felt quite tired. I don't suppose I will be going back to Leicester again for some time; there is the AGM of the Society in November, but I don't think I want to get involved in their politics again.

A Day Out in Brighton

2010-09-03T08:08:00.003+01:00

Yesterday, 1st September, I took the train to Brighton with the aim of attending the meeting in the evening of the Brighton and Hove Humanist Society. The speaker was Denis Cobell, a former President of the NSS, on "Why I am Not a Christian", though in fact it was mostly about his upbringing, in the Brighton area, within an Evangelical family.

Since the talk only began at 8 pm I spent most of the three hours preceding in the Odeon cinema, watching a very noisy film, "Inception" starring Leonardo DiCaprio which was about people who could set up realistic dream worlds, and dreams within dreams. Coming out at the end I wondered if I was back in the real world or not, especially as the way out of the cinema was something of a maze.

Another reason for going to Brighton was to visit the Apple store with a view to perhaps changing my computer for an iMac or MacBook. However the only address I had was Churchill Square which proved to be a large shopping mall, and despite walking round most of it, never found the Apple store, or any map of the place! I did get some fish and chips at the BHS restaurant, and a couple of cotton Oxford shirts at the M&S store opposite (since they don't seem to be available in Hastings).

I also found time to sun myself on the beach for a while, though Brighton Beach was indeed very crowded, as it is traditionally supposed to be.

Chess Talk and other Odd Events

2010-08-22T15:46:00.002+01:00

I've spent most of this week preparing a booklet on "Simple Chess Variants" for a talk at Hastings and St Leonards Chess Club. Although I only received one email from a member who said he would come, in the end the meeting went off reasonably well, since five others turned up at least for part of the time. I was only able to complete two bound copies of the booklet since my printer ran out of ink. I'll do some more later. It came to 14 A4 pages.

After the talk we tried out some variants. Progressive chess seems to be the most familiar and popular. I had some success with Cylinder chess. One player was familiar with Rifle chess, but considered that normal captures should also be allowed. A try-out with Double King chess was unexciting; the rules for checkmate of the two kings need to be clarified.

The previous week, having watched the first of the new Sherlock series on a flat-screen TV at the hotel in Lincoln, I decided to spend some money on a new television set, since the one I have is just a 14" portable. The local shop, Adams and Jarrett, supplied me with a 22" screen for under £200, made in India. I watched the first two parts of the "Matrix" series on successive nights, but missed the final part since the Richard Dawkins programme about Faith Schools was on at the same time. No doubt I'll get another opportunity to see the Matrix in future. The crazy scene where Neo fights ever-increasing clones of Agent Smith made me laugh. It reminded me of the old elaborate Busby Berkeley dance sequences.

As part of the rearrangements to put in the TV screen I put an old floor-standing pot plant, which came with the flat, outside the front of the building, where I thought it might do better. Within a couple of days it had vanished! Why would anyone steal an old browning pot plant, did they just want the pot? How did they take it? It was about four feet tall, awkward to carry any distance. It hasn't been dumped nearby. Are there gangs of professional plant stealers about? I didn't report the theft to the Police since I don't particularly want the plant back, and don't want to waste police time.

Travelling to and in London

2010-08-10T22:49:00.004+01:00

On Monday I went up to London for a Humanist Heritage meeting (as reported on the Hastings Humanists blog). Just going to London for a meeting is not really a good use of time and money, so I always try to fit in other activities.

I travelled up to London, and back, via Ashford and St Pancras, using the high speed train service that runs on that line. This was a bit more expensive than my usual route to Charing Cross, and the ride was not particularly smooth, especially in the tunnel between the Stratford and Rainham area where it vibrated rather noticeably from side to side. So I don't think I will use that route again.

I took a bus to Queensway to check out if the old Ethical Church was still there.
(see the HH blog for photo). Afterwards I spent some the time walking through Kensington Gardens and Hyde Park, seeing the Diana fountain for the first time, though it seems to be more of a paddling pool than a fountain, and on this hot day was crowded with children.

I also walked down Exhibition Road and visited the Victoria and Albert museum for the first time. I must certainly go back there again for a longer exploration. Previously I've only visited the Science and Natural History Museums.

The whole of Exhibition Road and half of Oxford Street were being dug up, which didn't assist the bus traffic, so I ended up a bit late for the meeting, but don't think I missed much.

Archiving the Ether

2010-08-05T21:31:00.003+01:00

I've been trying to sort out all the files in the "My Documents" section of the computer. These included several lists of "Old Favourites" from previous computers. Naturally a lot of these coincided with those on my current list, but a surprisingly large number of old links have just vanished into the ether. There were quite a number on the "geocities" site which it seems Yahoo took over and closed down. There are now a number of archiving sites where old web pages are kept, for instance the British Library now has a webarchive, and there is an American internet archive based in San Francisco.

This week I received another letter from Professor Donald Knuth, enclosing four chapters on knight's tours from his forthcoming "Fun and Games" book. They cover non-intersecting knight paths, celtic tours (which include no minimal triangles), tours on three-rank boards, and longer leaper tours. As might be expected his idea of "fun and games" extends to some quite complicated mathematics. I'm naturally pleased to see that quite a number of my own results are quoted.

Circular Chess in Lincoln

2010-07-28T19:55:00.004+01:00

I went to Lincoln 24-26 July for the Circular Chess again as has become an annual custom with me. The B&B where I usually stay was booked up, so this year I stayed at the Hillcrest Hotel, which is in a very pleasant area overlooking the Arboretum. There were twelve entrants this year and an all-play-all tournament was arranged with each player getting fifteen minutes on the clock. This rapid-play I thought would not suit me, but I did win the first two games, but lost the rest on the time limit, despite often having a superior position. The heat also did not help. John Beasley was there, but only as an observer. The winner once again was Francis Bowers, who had the difficult task of meeting me in the last round. On the Saturday before the tournament I managed to get in a swim at the Yarborough leisure centre, but may have overdone it a bit, since I had a stiff back the next day, but perhaps that was due to the soft bed at the hotel.

My Photograph Collection

2010-07-23T00:14:00.004+01:00

Today and yesterday I have been catching up with updating my flickr photostream which I had neglected for a long while. The idea is to put in it what are the best of my photos, although looking back some of those chosen seem questionable. Since they are available for anyone to copy (though please include an acknowledgment) they also tend to be images others may find useful. For instance some are shared with the Humanist Heritage Group on flickr. Nearly all are town and country landscapes, mostly devoid of people, which may say something about my solitary nature. I like to make pictures with the main subject clearly framed, with no bits cut off. I also like to try to see things from an unusual angle if possible. Some of the photos are classified into sets for the geographic areas in which they were taken, namely London (including Greenwich), Leicester, Lincoln and Hastings (including St Leonards).

Exact Echoes

2010-07-20T23:26:00.004+01:00

After a 25 year lapse of time I have at last completed this 50-page A4 PDF booklet which derives from the successful ‘Exact Echoes Tourney’ which was announced in Chessics issue 15 in 1983, entries being published in issues 17 to 21 and the award in issue 23 in 1985. Composers were asked to send in not only their original compositions but also outstanding examples of their previous work, or the work of others that they considered should not be missed, with a view to publishing a booklet on the subject. I have not so far attempted to bring the collection up to date to cover work done in the intervening years, but may yet make a few minor improvements. It is available on my publications page.

I've just noticed that in Safari, the browser I am now using, the box of text runs off the righthand side of the screen. This must be due to a different interpretation of the CSS instructions as compared with Internet Explorer. I must try to correct it.

I went to the Hastings Chess Club AGM on Sunday, but didn't find it a very encouraging experience. Perhaps I've had a glut of AGMs this past week. I was at the BHA AGM in London on Saturday, as reported on the Hastings Humanists blog, and the Arts Forum AGM on Tuesday. Fortunately I postponed the Hastings Humanists AGM to November. In July it is too hot to think.

A Chequerboard of Afternoons and Evenings

2010-07-15T21:22:00.005+01:00

On Tuesday afternoon I went the unveiling of some new sculptures at the "Chess Square" at the end George Street in Hastings Old Town. They depict a sea-horse, an octopus wrestling with a chess rook, and a sea serpent, I think. I didn't notice anyone from the chess club there, but there were several Councillors, including Dom Sebatian who sometimes comes to our Humanist meetings. The chess pieces for use on the board painted on the ground are kept in a cupboard against the wall of Butler's Emporium, and the key can apparently be obtained from the West Hill Lift Office, further along George Street, for a returnable deposit. It might be an idea for the chess club to put on a demonstration now and again.

In the evening I went to the AGM of the Hastings Arts Forum. It's a surprisingly large organisation, since the quorum required was nearly 50. They met in one of the sections of the Azur restaurant on the lower promenade. I was there just to see the venue and to get a better idea of the people behind the venture, and its recent history of recovery from financial problems.

On Wednesday afternoon I managed to arrange for a man from Sussex Bin Cleaning to come and clean our bins which were in a disgusting state. I found the company on the web, at the suggestion of my landlord, Mr Griffiths, since the Hastings Council do not provide a bin-cleaning service and indeed could not suggest anyone to do the work. He will be coming monthly to keep the bins clean from now on.

On Thursday afternoon Mr Griffiths arrived and took away most of the rubbish that had accumulated on the old sofa that had been dumped in front of the flats. I'm wondering what to do to stop more stuff being dumped there. Some plants in pots perhaps? The Council will remove fly-tipping but only of it is on public land, so perhaps that means redumping it on the pavement, although if you are seen doing that presumably there is a fine, so you can't win either way.

It's A Humanist Life

2010-07-09T22:47:00.004+01:00

I've not posted anything here for a while, since I've been mostly occupied with Humanism, which is dealt with on my other blog for the Hastings Humanists.

On 15 June My Humanist Hero essay on Robert Owen was published on HumanistLife. It was the second in what is now a long series.

I've also been contributing a number of biographical and descriptive pieces to the new Humanist Heritage site. For example, the entries for Down House, Leicester Secular Society, Alan Turing, Paul Dirac, and Richard Carlile are mostly mine, though of course the information in these articles is not new.

On 26 June I went to the BHA Conference on Humanism, Philosophy and Arts at Conway Hall.

On 3-4 July I went to Lewes to join in celebrations of Tom Paine.

The Wider View

2010-06-19T11:52:00.005+01:00

This is the wider photo that I took before the telescopic image posted last time. It has been enhanced slightly so the houses are not completely black.

This week I've been getting more minor nose-bleeds. I did think of making an appointment to see the doctor, but their system seems likely to raise my blood pressure more than anything else. Speaking to the receptionist at the counter she was reluctant to arrange anything except a month ahead, and to book on the actual day you have to phone between 8:30 and 9:15 in the morning. Obviously they are completely overworked. So I decided to leave it for now, and nothing has recurred.

I've been getting a series of emails from an chap in St Albans who has very vague plans to set up a chess variants organisation to replace BCVS, but he keeps using my name and that of Variant Chess as if I've already given approval to his efforts. This has not done my blood pressure any good either.

I've also entered the Hastings Chess Club Summer tournaments, those that are not rapid-play at any rate. The first opponent I contacted failed to turn up at the appointed time, but I did get a friendly game, which I won. I've agreed to rearrange the appointment for next week, though apparently I could have claimed the win by default, but really I just need the practice.

Sky View

2010-06-13T21:48:00.003+01:00

Fantastic sky this evening, about 8 pm. The seagull seems to think so too. Photo taken through a window of my living room, using a telescopic setting.

Mathematical Art: A Chessboard Mosaic

2010-06-03T12:18:00.007+01:00

Over the bank holiday weekend I spent some time drawing and colouring the pattern shown here. It is a "Chessboard Mosaic" of the type I described in The Games and Puzzles Journal (Vol.1 No.4, March-April 1988, p.64) but on a larger scale. Varied patterns of this type can be formed by first numbering the cells of a chessboard 1 to 64 in some fashion. This example is derived from the numbering of the first Magic Knight's Tour, discovered by William Beverley in 1848. It is a 64 by 64 matrix; when numbered 1 to 64 along the top and left edges, a mark in the square where the r row meets the s column indicates that a piece can move from cell r to cell s. In this example the dark cells indicate rook moves, the yellow cells bishop moves and the red cells knight moves. The pattern is symmetric about the principal diagonal since these moves are all reversible. The rook move pattern is symmetric about the secondary diagonal, but the knight and bishop patterns deviate slightly from this symmetry, due to the nature of the Beverley numbering. The red railway-line pattern down the main diagonal is the result of using a knight's tour numbering, since r is always connected to r+1 by a knight move. The apparent figure "8"s on the main diagonal derive from several zigzag pattern of knight moves in the tour wheren the first and third and second and fourth cells are in the same rank or file and thus connected by a rook move. I'm wondering whether I should exhibit this at the Art Forum; apparently any member can exhibit one item free; but is it really Art?

Edit: I've replaced the original image by an enhanced version, since it came out too gray. The background I used was in fact a sheet of white card.

An Afternoon Walk

2010-06-01T21:46:00.005+01:00

This afternoon I took a walk along to the Arts Forum to have another look at the exhibition of paintings by Katherine Reekie "Artists on the Beach" which feature images based on well known works by famous painters like Matisse and Picasso, and sculptors like Moore and Gormley, against a background of Hastings images. It's quite a fun idea.

I went on to walk to the Garden Centre along the Bexhill Road to see if they have anything in the way of a compost bin. They only had two old ones with bits missing. I'm thinking of installing a bin by the front garden so that I can dig up all the weeds and compost them. It's getting rather overgrown.

I carried on walking to the Glyne Gap and then back to Hastings along the beach path. At the old bathing pool site I noticed that the seagulls seemed to have some small shellfish that they were dropping from a height to crack open, or else they were practising with pebbles. Further along the promenade a black-headed gull was flying along the surf line and repeatedly landing on the sea only to immediately rise again. Presumably it was catching something to eat.

Finally I went into a supermarket to top up a few things for my own larder. I ought to be getting out more regularly for exercise, but seem to be leaving it for days and then taking it all in one go.

Computer Modifications

2010-05-26T20:17:00.003+01:00

This week I've been trying out some alternative browsers on my computer. A while back there was a "Browser Choice" message that came from the European Union, which listed a range of different browsers, with the idea I think of creating a more level playing field for them to compete with Internet Explorer provided by Microsoft with Windows. Since IE has increasingly been incapable of showing some video connections, and there are threats to update it to a form that will not work with XP, I decided to try a change.

A few years ago I tried 'Firefox' but wasn't keen on it, though perhaps I didn't find the right settings to suit me. This time I tried 'Opera', but found I could only reconstitute my list of favourites from IE by transferring them one at a time. Also the 'circle dial' thing on it was a bit puzzling, and included advertising. The second one I have tried is 'Safari'. This turned out to have a button in the Bookmarks section which allowed all the favourites to be transferred automatically. It also seems to be nice and simple, which is what appeals to me.

Earlier to day I also got an instruction from Virgin Media to install their new Security 9 system to replace PC Guard. This I was glad to do since I have the impression that it is PC Guard that has been slowing everything down. The installation went reasonably straightforwardly. However I did get a message that something called "rpcapd" was trying to get through the firewall. Not having any indication of what this is I blocked it.

Wolfe, Water and Wine

2010-05-20T15:58:00.004+01:00

This is a closer up photo of the statue of General Wolfe in Greenwich Park. He stands on the brink of the hill looking down towards the Queen's House and the National Maritime Museum, with the Royal Naval College buildings beyond them, and the Millennium Dome to the right, and across the river to the skyscrapers at Canary Wharf. That is the view all the sightseers around the plinth of the statue are looking towards.

On Tuesday this week I woke about six and went for an early morning swim again at the baths, as well as disposing of my accumulated glass waste, and some left by other tenants, at the bottle bank. Immediately after I returned at 8:30 the "parcelforce" man came with a box which contained six bottles of wine that I'd won for writing a letter that was featured in the New Humanist magazine. Since I'm not much of a drinker of alcohol I will have to find someone else to drink most of it, or else it will last me six years or so.

Greenwich Park

2010-05-17T16:23:00.006+01:00

This is another photo from my trip down the river on Thursday 6th May. It is a view from the Queen's House in Greenwich Park, looking up towards the statue of General Wolfe on the left and Flamsteed's old Royal Observatory on the right. This is one of my favourite places in London. There happens to be the very faint image of a monoplane coming out of the cloud at the top right. (Click on the photo and use the magnifier!) I wasn't able to take a tour round the observatory since it was already packed out with visitors.

I did look in the National Maritime Museum and the Queen's House for a while, but the art exhibitions are in such dim lighting now, and I couldn't find the famous portrait of Stoker Martin that I remember seeing there. EDIT: I've added in a link to an article in Life magazine from 1948 which includes a copy of the portrait.

Canary Wharf

2010-05-12T13:22:00.004+01:00

There really is a Canary Wharf where the river buses dock as this photo I took on my trip last Thursday shows. The buildings above are of course the place where the power of the money markets now resides. Are they now our real masters? It's not my pun but it nicely sums up the results of the election and I can't resist quoting it: We are all Con-Dem'd!

On the River

2010-05-09T21:31:00.004+01:00

This is a photo I took on Thursday as the Thames river-bus was about to pass under Tower Bridge on the way down to Greenwich. I was surprised to find that I had taken 50 photos in all when I came to transfer them to the computer. Of course, most of them were not very good. I must get round to putting the best of them onto my Flickr page, which I've been neglecting for some time. I also got quite a good one when the boat stopped at Canary Wharf en route.

Perhaps I should add the results of the election. The sitting Labour MP, Michael Foster was defeated by the Conservative candidate Amber Rudd. On the other hand the Labour Councillor Jeremy Birch won, and in fact Labour took control of the Council.
Here is a report from the Hastings Observer website.

Visiting My Old School

2010-05-07T09:35:00.007+01:00

I'm rather stiff and tired after a long and busy day in London yesterday. It began at 7:30 when I went to the polling station to vote. In the end I decided to stick to voting for the people I know, which happen to be the Labour candidates, Michael Foster for MP and Jeremy Birch for Councillor. The trouble with a PR system it seems to me would be getting to know all the other candidates so that one could make a considered choice, rather than making a vote purely on the party line, not knowing what the individual candidates were like, never having met them.

The main reason for going to London was for the chance to look round the bulding that used to be St Olaves Grammar School which I attended from 1951 to 58. It proved to be somewhat dispiriting to see it in it's current condition. It is now owned by a property company, Berkley Homes, and there are plans to convert it into a hotel. The playground at the back has been dug up, the exit to that area having been bricked up, and a wing where the art classes were held has been demolished. All the rooms were empty of furniture and decorations, so it was really rather sad to see. The photo is of the assembly hall. The white spots are probably reflections of the flash from specks of dust in the air.

Some parties of boys from the new school in Orpington also came to see the building, but they seem to have had very little time to see anything, and I doubt if they learnt much from the experience. Some of the Old Olavians who were taking them round seemed to me to be spinning them tall tales, and reliving their childhood conflicts with the headmaster, Dr Carrington, rather than explaining anything of genuine historical interest.

There was to be a Commemoration Service in Southwark Cathedral from 2pm, but since it was such a lovely sunny day I couldn't face the dark interior of another building and instead took a trip on the river-bus down to Greenwich, which like to visit at least once a year. More on that perhaps in a separate diary entry.

Waste Disposal Woes

2010-05-04T21:15:00.005+01:00

All this morning I spent tidying up the mess left by the bin-men. The photo shows bits of rubbish lying all over the place, and the bins left open. (This was before the second collection where they take the pink recycling bags.) This is not entirely their fault as the black bag left on the ground contained empty glass bottles, which are not supposed to be put in the bins, but they could have taken the rest.

We had a circular a few days ago, resulting from my enquiries, which makes clear that the Council now requires all rubbish placed in bins to be in black bags, not loose. Instead of emptying the bins they now take out the black bags, put them in another bin, and empty that bin into the dust-cart!

I emptied out the bins and put the uncollected rubbish from several weeks into new black bags for collection next week. There was also a number of items that should not have been in the bins, such as two heavy bags of builders rubble! Some of the rubbish included cat-litter - should this be disposed of in this way? One of the bags at the bottom was full of maggots. These I swept onto the garden in the expectation that nature will deal with them.

The white object on the right is a sofa which has been left there for several weeks. No-one in the flats claims responsibility for it. I suppose it will be up to me to arrange for it, and the other unbinnable waste to be disposed of.

It was nice to see a new winner of the World Snooker Championship last night, and an overseas player, Neil Robertson from Australia. My viewing was interrupted by the fire alarm going off just before midnight, a result of the tenant in Flat 3 trying to cook himself a late snack. This afternoon his overflow was running, and still is, though I pointed it out to him.

Echoes

2010-05-01T21:29:00.003+01:00

I had another nosebleed on Friday, this time it occurred at an awkward moment as I was checking out at a small supermarket. Holding my nose and putting things in my bags at the same time was a bit awkward. A few drops fell onto my newly washed nylon bag, so it's going to need another wash! When I saw the doctor last year they concluded it was due to a weak vessel in my nose, but why it should recur at this time I don't know.

This morning I took another longish walk, this time up to the West Hill where the Castle is, and back through the Old Town via Croft Road. This will be the new route for the Jack-in-the-Green ceremony on Monday, so I thought I'd check it out since I missed it last year. There was a group of male-voice folk-singers outside the Jenny Lind pub, and a group of Morris Dancers at the entrance to Rock-a-Nore Road, but I couldn't see much since they were surrounded by a crowd. I ended with a walk along the beach. There was quite a strong wind coming off the sea.

During the week I've spent a lot of time typing up a collection of Exact Echo chess problems that I made about 25 years ago, with the help of various correspondents. It was intended to publish a booklet of them as a follow-up to the Exact Echoes tourney that I held in my little magazine Chessics. It was abandoned at the time because of competition from Eugene Albert's Encyclopedia of Ideal Mate Chess Problems, that would have contained many problems of this type. I presume that appeared, though I never followed it up, my interests having moved elsewhere.

Little Incidents

2010-04-23T20:53:00.003+01:00

Today I went out for the first time this year without a coat. I'm always a bit slow to get round to losing my winter wear, until I start sweating. In fact I'm not really very good dealing with summer weather. By the time I get round to short sleeves winter is about to set in again, and I've never worn shorts since I was about six, even when cycling.

A few days ago I went into the temple-like public convenience in Hastings town centre and happened to somehow drop the empty bag that I was carrying under my arm into the gutter of the urinal. It's a bag I've had for years and grown attached to. At first I thought this was maybe the end of it, but I've never been able to find a replacement for it although it had got dirty over the years, so I decided to risk putting it in the washing machine. It survived and came up looking almost as good as new! It has the label "Guardsman" in red on the side, and inside is a small label with the legend: "Cat No. N5159, MADE IN CHINA, Z804, 100% NYLON." Perhaps this may be sufficient to trace whether they are still made.

Someone from the five other flats in the building where I live has put out an old sofa in the front patio (if that's the word). It has been there for over a week. I don't know whether they think the council's waste disposal men will take it away. They won't. I've put a little notice on the inside of the front door asking for whoever put it there to make arrangements to have it removed. Whether this will have any effect remains to be seen.

This morning I had a small nose-bleed. This is the first time it's happened since I had a long bout of nosebleeds last year and had to see the doctor about them. I hope it's just a once-off and not the start of a series again.

Spring in my Steps

2010-04-14T21:13:00.005+01:00

I went for a walk along to the Arts Forum this afternoon to check that it was all in order for the Hastings Humanists meeting tomorrow evening. Although it was dull when I set out the sun soon came out and I carried on along the front as far as the railway bridge, then turned up St Saviours Road and Filsham Road as far as Silverhill. The Silverhill Computers shop is now empty, the business having moved down to the bottom of London Road.

From there I continued walking through Alexandra Park. On Shornden Reservoir, among the many seagulls, there was a lone black-plumed bird with a long beak which I think must be a cormorant. It was repeatedly diving below the surface, emerging several feet away, usually with a small fish in its beak. It's a pity I didn't take my camera, but I hadn't planned the walk beforehand.

In the park the birds were singing and the grey squirrels were busy. I saw very few people until I reached the section nearer the town centre. I ended up at the town hall and remembered to pick up some pink bags for the recycling. I've given up putting any rubbish in the two bins outside my flat, since the refuse collectors are no longer emptying them properly.

My Website Reorganised

2010-04-11T19:24:00.004+01:00

This Sunday I've spent most of my time at the computer rearranging the material on my mayhematics.com website. Most of the content is unchanged, it is just the way the pages are classified that has changed. The Index page now leads to three sitemaps, one covering Chessics and the others Reality and Fantasy. It took much more work than I expected, and several FTP sessions, to get all the links, forward and backward, to work correctly.

I've more or less given up on CSS (Cascading Style Sheet) methods, finding them more trouble than they are worth, particularly if you want to change anything. I've reverted to simple HTML. All necessary styling, which I keep to the minimum, is all on the page itself.

There is one new item, namely a version of the missing Issue 45 of the Games and Puzzles Journal, which was lost but now is partially found. It comprises only three articles, the others needing further work.

The website got confused when NTL closed down my old Home pages and I was forced to squeeze them into the mayhematics site. The different sets of material are now much more spaciously arranged, which should allow for ease of development.

Art Appreciation

2010-04-02T18:21:00.003+01:00

Since the Hastings Humanists have been meeting at the Arts Forum where paintings and other art works are on show, I have been taking more interest in art. The exhibitions there are changed every couple of weeks. There is quite a range of different types of artwork on show.

Last week's exhibition was mainly of oil and acrylic paintings by a Canadian artist, showing colourful landscape scenes. However only one of them appealed to me to the extent of thinking it might be good to have on the walls of my flat. While clearly being a representation of sea and cliffs, it was also clearly an abstract pattern. I've come to the conclusion that this it what appeals to me more than either fully representational art or completely abstract.

The exhibition this week, in both Arts Forum galleries, is of very abstract work that I'm afraid has no appeal for me at all. It seems to me that the artists have spent more time on thinking up fanciful titles for their work than actually producing them.

On Thursday, when I went to look at the History House in Hastings Old Town, as a possible future venue for Hastings Humanists, I also chanced to see that there was an exhibition on at the Bourne Hall nearby. Most of the pictures there were merely representational. There was one of the head of a panther peering out of darkness that combined real and abstract in the way described above.

I'm tempted to start buying some paintings for my flat, though I'm not supposed to make any holes in the walls, so there might be a problem in displaying them. Also the prices can be quite high, but on the other hand good art should remain quite saleable, so perhaps it is not too great an extravagance.

More Chess Practice

2010-03-31T19:29:00.003+01:00

On Saturday (27th) I joined in a rapid-play chess tournament (Swiss style 7 rounds) at the Hastings chess club, but only managed to score 1.5 (a win and a draw). I've not really got the idea of how to play so fast.

On Monday evening I got soaked on my way to the club to join the club secretary and another player to be taken by car to Cranbrook for a return match with the Kent team we met previously. A fourth team member travelled separately. I had the same opponent, but this time lost, though the game was very similar and just as long by time. This was not rapid play but 75 minutes plus another 15 minutes at the end, much more to my taste. Again I found myself a knight down but with a passed pawn. The team score was 2 points each.

When I arrived back I was concerned not to be able to find the pair of glasses that I use for looking at computer screens, and for chess play, but fortunately it turned out the spectacle case had just slid out of my jacket pocket onto the car seat, and hadn't been left behind in Cranbrook.

I'm looking on all these games as practice at getting back into the routine of orthodox chess, but I don't seem to be making very fast progress.

Spring: Time for New Developments

2010-03-17T19:50:00.006Z

Now that, it seems, Spring is at last here, I've started waking up earlier, or at least not going back to sleep. So there is something to the idea that one tends to go into hibernation in the winter. I was up at six this morning and went for a swim at the baths between seven and eight. Whether I will be able to keep this up regularly remains to be seen.

One of the sounds that now greets me on waking is that of the blackbird, who seems to start singing before the noisy gulls get going. I've always liked the song of the blackbirds. They seem to be speaking to me personally, they often sound as if they are saying "What'ya doin' Georgie". Not that I like any one else being that familiar. My father was also named George, so I got the diminutive version.

It looks as though the British Chess Variants Society will close down this year, since John Beasley is retiring and no replacement has come forward to act as secretary and editor. Also Peter Fayers will not be able to carry on as treasurer and publishing manager. I will probably try to keep the magazine Variant Chess going in some form on the web, but not produce a printed version.

I've been looking into the costs of registering suitable internet addresses, to reorganise my web content, including the magazine. Because my "ntlworld" site was closed I've had to cram all my stuff onto the "mayhematics" site, which was not my original plan. There are also moves afoot to form some sort of International Variant Chess Society. This would be a welcome development, but needs a new generation of internet-savvy enthusdiasts to develop it.

Chess and Mathematics

2010-03-13T10:30:00.003Z

Last Monday I took part in a chess match, playing on behalf of the Hastings club against a team of four from Kent. I was on the third board. The time allowance was quite generous, which suits my slow play, and I managed a draw. Most of the time I was a knight down, but with the advantage of a passed pawn, so it was a matter of trying to get the pawn promoted. There were a lot of interesting tactical situations that arose the game. The opposing team won overall by 2.5 to 1.5.

On Wednesday I received a letter from Professor Donald E. Knuth of Stanford University. We have previously corresponded on knight's tours, but I hadn't had a letter from him for several years. He is putting together a book of his Selected Papers on Fun and Games which will include several chapters on tours, among much else. I had to look up what "potrzebie" was all about. It seems it's a Polish word adopted by MAD Magazine as a running joke back in the 1960s.

The topic Prof Knuth was asking about concerned the results obtained by Robin H. Merson on non-intersecting knight's paths. As a result I have now placed PDF versions of Robin Merson's two main letters to me, dealing with open and closed paths, on the knight's tours page of my mayhematics website. They haven't scanned very clearly; for instance the background graph lines have not come out, but that's the best I can do at present.

Prof Knuth also likes to collect the middle names of everyone whose work he cites, but I was unable to locate what Robin Merson's "H" stood for. He worked for the Royal Aircraft Establishment at Farnborough on the use of satellites for mapping the Earth, among other activities.

Puzzle Addiction

2010-03-05T13:27:00.003Z

Every week, though not every day, I buy a few newspapers, mainly for the puzzles rather than the news. On Friday for instance the Guardian has a sudoku and kakuro that are usually a bit harder than during the week. The Guardian on Saturday always has a good prize crossword, often by Araucaria, but I don't always buy it because it has far too many sections, on subjects such as sport, travel, finance, fashion and so on, that I'm not really interested in.

I also tend to get the Times once or twice a week, mainly for the crossword and the killer sudoku. However this week the Times has started to include a four-page puzzle section every day! This will mean that I have to avoid buying the Times in future, because once I start on the puzzles I have the compulsion to solve them all, and waste most of the day when I should be doing something productive. Why they have changed to this new scheme I don't know, I thought their previous policy was just the right balance.

More Random Thoughts

2010-02-27T15:11:00.003Z

I spent most of Thursday journeying to and from Uckfield to attend the East Sussex SACRE meeting on behalf of Hastings Humanists. Since I have a Senior Railcard and a Buspass this was not expensive, just time-consuming. When I returned, and all next day, I had a headache. Whether this was due to bumping about on the bus, or waiting for it in the cold and wet, or some other cause I'm not sure, but at least it seems to have cleared up today. At any rate it stopped me going to the chess club on Friday evening.

While in Uckfield I chanced to go into a Health Food shop and bought a jar of Barley Cup as a possible substitute for drinkng too much Coffee. It doesn't have any distinctive taste that I can detect, just a smooth texture. I did try flavouring it with some Malt Extract, bought at the same shop, but Honey would probably be better. Since I arrived in plenty of time for the meeting I looked around to see what cafes were available and ended up in a Poppins restaurant, which provided a nice lesagna with baked potato and salad.

I'm still working on the knight's tours book. I had hoped to get it finished for my 70 th birthday, but there is still a lot to be done. At present I'm on the chapter dealing with tours on oblong boards. I completely rechecked the tours on the 3x9 board, finding 146 as reported on the KTN website back in year 2000, although there is a minor misprint there, the number of {1,1} tours, with ends a diagonal step apart, is 28 not 29. The next section to check is on the 4xn boards, where I did some work trying to generate recursion relations for the numbers of half-tours, which has never yet been reported on the KTN site.

Random Thoughts

2010-02-20T23:33:00.004Z

I played another couple of chess games on Friday evening, at a slow rate without clocks, and won both of them against a player who seemed quite strong, so perhaps I'm getting back into the right frame of mind. One ended in a knight checkmate, the other in a queen against rook superiority. The more rapid play games which we played on previous weeks require one to react much more instinctively, rather than contemplate each move carefully.

Why are there no longer any malt-flavoured cereals being produced? I used to like malted shreddies when they were produced by Rowntrees, but as soon as Nescafe took them over they changed the recipe so that the malt taste was far less. I complained at the time, but got no helpful response. Now they have removed the malt altogether! This seems to be part of their policy of claiming that everything is "whole grain".

My article on "Howard Jacobson and the Temple of Darwin" appeared on the new HumanistLife website on my 70th birthday, 8th February, but has not attracted any comments. Perhaps this means that it is perfect as it is and doesn't need any further comments? Probably not! I'm glad to see that more articles are appearing with a greater frequency now. There are strong disagreements between Humanists on a number of issues, for instance the assisted dying question, and whether the burka should be banned. These have attracted the most comments.

The Religion of Infinity

2010-02-11T01:42:00.004Z

I happened to notice that the Horizon programme on BBC2 TV this evening was about "Infinity and Beyond". Hoping to learn of some new research I tuned in but was sorely disappointed. The programme was aimed at about the intellectual level of a five-year-old. The commentary was given by an Aleister Crowley lookalike who was filmed in murky black and white endlessly walking up stairs and reappearing again, Escher-like, on the bottom landing, and making pompous and portentous-sounding statements and poses. Half-way through he even renamed Georg Cantor "Gregor".

All the usual elementary illustrations of infinity were included, such as Hilbert's Hotel, Cantor's diagonal argument and monkeys typing Shakespeare, followed by speculation about whether the universe might be infinite. There was one chap who didn't believe in infinity, but all he could say was that there was a largest number, but no-one knows what it is, and it is followed by zero.

My argument for finitism runs as follows: It is true that we can generate symbols for numbers in a systematic manner using the ten digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 and the positional convention, but this does not mean that the set of all such symbols 'exists' already until we actually construct it. Nor does the mere construction of a symbol, such as n+1 for a number imply that the number 'exists' in this sense.

The mathematical term 'finite' applies to sets of things and the numbers of things in those sets: a set is said to be finite if it has the sensible property that it cannot be placed in one-to-one correspondence with a part of itself; a number is finite if it describes the size of a finite set. The Finitist maintains that all sets, and therefore all numbers, are in fact finite.

In order to introduce infinity into mathematics it is necessary to postulate that it exists, or to assume some other axiom that implies this, for instance Peano's axiom that every number has an immediate successor. Further the properties of infinities depend on the axioms that are chosen. For example Paul Cohen proved that, under the usual axioms for arithmetic, it is impossible to say whether there is an infinity between that of the integers and the real numbers.

On the other hand the properties of finite sets and numbers are a matter of physical fact, at least within the 'realisable' realm, where they can be applied to material objects. Statements about 'all' numbers, such as Goldbach's conjecture, may not be realisable.

What do we mean by saying that something 'really exists'? The simplest definition is that something exists if it is material, that is if it has measurable mass. On this basis it might be argued that 'ideas' like numbers do not exist since they are immaterial. But are they? Ideas exist in the minds of people, and presumably therefore they exist materially in the form of electrical or chemical energy in the brains of those who think about them. By Einstein's equation, E = mc², anything that has energy has corresponding mass. So if mathematician's brains really contained the infinite set of all whole numbers they would have infinite mass and implode into a black hole!

By a similar argument, the universe is finite in mass, since if it were infinite there would be infinite gravitational force at every point in the universe (a version of Olbers' paradox).

Even if we discount the argument by weight, so long as we accept that ideas exist in the form of electrical or chemical configurations in the brains of thinkers, there can still only be a finite number of ideas in existence, certainly of human ideas, held by human beings, because there is only a very finite number of human beings extant, and their brains contain only finite numbers of neurons.

EDIT: In contrast to the puerile "Horizon", Melvyn Bragg's "In Our Time" on Radio 4 this morning was an adult-level programme about "unintended consequences" in mathematics, on how ideas developed purely out of mathematical interest later prove to have practical consequences: such as prime number theory in cryptography, complex numbers in alternating electrics, and non-euclidean geometry in relativity. Why does TV have to dumb-down, while Radio does ideas so well?

More Chess

2010-02-05T22:50:00.003Z

More chess this Friday evening, a six-player all-play-all with twenty minutes on the clock. I was given a low grading of 80 and had 13 minutes to 7, or 15 minutes to 5, depending on opponents' gradings. This time I won two, though my opponents in those games were either distracted by the time handicap, or thought I needed a win. Both ended in a straightforward queen checkmate. I did deliberately try to play in a more attacking style compared with last time.

I've been feeling rather tired in the afternoons lately, and unable to rouse myself to get much done. Perhaps I need to keep more regular hours, or perhaps I will come out of hibernation when the weather warms up a bit.

A Busy Week in London

2010-01-31T00:10:00.004Z

On Thursday evening I returned from a two-day visit to London, but I haven't been able to report on it until now since my internet connection has been down, due to a fault at Virgin Media.

On the Wednesday afternoon I had booked a visit to the Cocoon at the Natural History Museum, and in the evening went to the 'Evict the Bishops' debate at the Houses of Parliament. These were both something of a disappointment. I've submitted an article to HumanistLife relating to the first topic, and have reported on the second on the Hastings Humanists blog. The cheap hotel room I stayed in overnight was also not to be recommended.

On Thursday afternoon however I had the much more pleasant experience of going to the Albert Hall to see the Cirque du Soleil production called "Varekai". Their show is a sort of mixture of circus, theatre and ballet. To appreciate it best I think you need to book a seat facing the stage and probably on the flat, though these seats are the more expensive for that reason. I was in a box high up on one side. From there you can see all the workings of the stage. They make extensive use of trap doors through which characters regularly appear and disappear. There are all the usual circus attractions, but no animals of course, though many of their costumes resemble strange creatures.

On Friday evening at the chess club I was inveigled into an all-play-all rapid chess tournament, and despite being allowed a handicap of 15 minutes against 5 minutes playing time against strong opponents managed to lose all my eight games, though they all went close to the wire.

So it was a busy week. More on it later perhaps.

Chess, Music and Euthanasia

2010-01-27T09:03:00.004Z

This is a photo I took on Monday of the Hastings Chess Club premises in Cornwallis Terrace. As you can see, like many places in Hastings, they hardly conform to the requirements of disabled access. The steps up to the front door could hardly be more precipitous!

Besides chess I've started to take an interest once more in music, with a view to playing or composing, probably with an electronic keyboard. Besides loking at various keyboards in a local music shop, and searching for details online, I borrowed a book "Play it Again" from the public library. This gave some useful website links and they are now listed on a page of my website devoted to Music.

Last week I also received a bowel cancer test kit through the post from the NHS. Taking smears for the test was not a very pleasant occupation, it must be very embarrassing for people who are unable to do them without assistance. According to the news this morning everyone who attends hospital is now to be tested for liability to thrombosis. Is this determination to keep more people living longer really a good thing? I see Martin Amis is advocating the provision of euthanasia booths on street corners where the decrepit are to be encouraged to end it all!

More Chess

2010-01-22T23:46:00.004Z

I've continued with trying to get back into playing chess, with visits to the Hastings Chess Club on Tuesday afternoon and again on Friday evening. My results have not been great, especially one game against a really strong player who just walked all over me, metaphorically speaking. I'm still walking into pins and forks and batteries and leaving pieces en prise, but given time I am managing to defend reasonably soundly against players of club strength, and finding a few combinations. There's an interesting article by Gary Kasparov on "The Chess Master and The Computer", which was linked to on the new HumanistLife forum.

Earlier in the day I had an appointment with the bank to discuss putting some money into an ISA, and also took out some Contents Insurance. There was also the possibility of adding my pedal cycle to this, but I judged it too expensive to do this. If it were stolen it would be just as cheap to buy a new one.

Joining the Chess Club

2010-01-16T20:49:00.003Z

On Friday Evening I at last got round to joining the Hastings Chess Club. I went along at 6:30 and left at about 8:30 after playing three games. Not having played orthodox chess, and very little variant chess, for ten years or more I lacked confidence that I could do any good without getting in some practice. The first two games however I drew, and the other I resigned. I did practice with a couple of games on the computer against the Zillions of Games version of chess. However it's going to take me quite a while to get up the confidence to play in tournaments again, as I did many years ago.

A Patchy Thaw

2010-01-12T21:55:00.002Z

I took advantage of the thaw on Monday afternoon to replenish some provisions. There were still some icy patches to watch out for, but the pavements along Norman Road were completely clear. Presumably the shopkeepers there had cleared the snow away.

This morning, Tuesday, the thaw was more complete, so I ventured out to Hastings town centre, but the pavements in Robertson Street and Wellington Place were still icy, though partially gritted. Oddly I found the pedestrian crossings in the town, for instance near Hastings station, were less safe to use than the road itself, since the ice doesn't seem to melt as fast on the special tiles that are used, in place of the old kerbs, to allow disabled access.

Later on I went to the area of Warrior Square station and Southwater, and there the snow was still uncleared and quite hazardous. I'd have thought clearance of the entrances and exits from stations would have had some priority.

More Snow

2010-01-10T10:29:00.003Z

We had a bit more snow yesterday but no more today so far, although more is forecast. I ventured out on Friday when there was a light covering, but only went as far as the Best One shop on the front near Warrior Square to ensure I had enough bread for the weekend, and to pick up the local paper to see if my press release about the Hastings Humanists meeting was included, which it was. I don't usually buy papers at a supermarket, since I object to the way many newsagents have been forced out of business, but it is no longer so easy to distinguish between them, they are all now mini-supermarkets.

The TV reports and papers are full of reminiscences abnout past years when there was heavy snow or long cold spells. I have reason to remember 1947 because I broke my right arm when I fell in the snow, coming down the steep hill from Purrett Road school in Plumstead. I remember it as quite a pleasant time, playing with my meccano set and learning to write with my left hand. I'm still somewhat ambidextrous.

When I moved into the flat here last December there were just lace curtains at the high windows. There were curtain runners above the windows, but no runners to slide on them, and I found they were obsolete. Curtains of the requisite length seemed not to be available off the shelf, and having them made would have been very expensive. In any case I wasn't convinced that they would give sufficient privacy, or be easy to open and close without having to get up on a chair or ladder.

My solution was to make a set of blinds. I bought some lengths of 1 by 1/2 inch wood from Winchester's at Ore to make the frames, and some good quality coloured sheets from the warehouse shop in Cambridge Road, and fixed them together using an upholsterer's staple gun. They are only flimsy, but have stood up well. I've just had to replace a few of the staples that were coming loose.

A Flurry of Snow

2010-01-05T14:29:00.004Z

This morning I tried putting on the gas central heating for the first time. I had been nervous about trying it, not having used a system like this before, but it worked fine. There are just four radiators of various sizes, in the living room, bedroom, bathroom and hallway. The pipes connecting them to the boiler must all run under the floorboards. I've got no instructions about how to adjust the radiators, but fortunately they worked OK as they are. I turned the system off when I went out. I'm wondering how much gas it will use if I leave it on for any length of time. There is just £20 on the card that I have to put in the meter in the basement. Now I hear on the News that the UK has only 8-days supply of gas, and we are heading into a cold spell!

In the morning I took the bus to the Ravenside Retail Park at Glyne Gap on the way to Bexhill. This was to take a portable DVD player into Curry's. I'd bought it in Leicester in April 2008 but it has developed a minor fault. It keeps going back to the start, or comes up with the message that the cover is open when it is not. After an exchange of a chain of emails with Curry's Customer Services department it was finally established that it is "a code 5 product", which means they are unable to service it. Why this might be they haven't said, it probably just needs a stronger spring to keep the cover shut. All they offered was a gift card, of unspecified value, as a contribution towards a replacement. To get this I had to take it to the nearest store and demonstrate the flaw to the staff there. Of course it worked perfectly there, so it was a wasted journey, though it was a nice bright morning.

Later I went out again to get in some food and a paper. On the way back it bagan to snow very lightly, and this was soon followed by a heavier flurry. This is what the photo shows. It didn't last long here but it has been very heavy in other parts of the country and more is forecast for the next few days.

Variant Chess Tournament

2010-01-01T16:01:00.003Z

I got an email from Mike Gunn about 6pm on New Years Eve that let me know there was a Variant chess tournament on at the White Rock Hotel. So I went along and took part. There were 14 players, and we played 7 rounds, a different variant in each round, the clocks were set at 7 miniutes per player. The variants were 1) Three-check chess, 2) Progressive chess, 3) Avalanche chess, 4) Triplet chess, 5) Pocket knights chess, 6) Static chess, 7) Losing chess. I scored 3 and 1/2. The winner with 6 points was a junior, who received the Encyclopedia of Chess Variants as his prize. This was an enjoyable way to end the year. I shall have to join the chess club and get in more practice. I've not played orthodox chess for at least ten years, and haven't felt confident enough to enter tournaments.

This morning I woke to find a layer of snow over everything, and a little still coming down. A pleasant start to the new year.

Newton Day

2009-12-26T12:46:00.005Z

I spent most of 25 December, Newton Day, appropriately doing some mathematics.

I've put together all my pages of notes on knight's tours to see if I can fit them into a reasonably sized book of around 250 pages. At present it is at around 350 pages, but further selection and editing should get it down to the right size. The pages are formatted to standard A4 size with inch margins, which allows four chessboard diagrams across the page.

The main problem I've had with the whole idea is to get the right balance between History and Theory. I now start with a chapter headed Chessics which introduces the theory, follow this with a chapter on lateral and diagonal movers, i.e. wazir and king tours, and then get to the knight, with more theory and tours by longer leapers and other pieces coming after. I'm not sure I like splitting the Theory section like this, but I do feel I'm making progress.

I had some items on knight's tours back in the first issue of Chessics published in 1976, which is now 33 years ago. I'm rather a slow worker.

In Wintry Mood

2009-12-18T23:19:00.004Z

This is a photo that echoes the first one that I posted here, on 2 February 2009, of the famous tree opposite my home, with snow on the boughs.

The people in Flat 2, on the ground floor next to mine, moved out a couple of days ago. They hadn't been there for more than six months it seems to me. Why they chose to move I've not found out. A better home for their cats and dog perhaps.

The bin-men seem to have adopted a new method of collecting the rubbish. Instead of wheeling our bins to the dust-cart and emptying them they now seem to take the bags out of our bins and put them in their bin and then empty their bin into the cart. This means that they leave behind any loose unbagged items in the bins. It will probably be up to me to put them in bags to ensure they are collected.

They have left one black bag however that appears to contain human excrement. Not that I've yet looked too closely at it. Why anyone should have put this in the bins I don't understand, nor who has put it out. I suppose it will be up to me to clear this away as well, but I'm not sure how to deal with it; empty it down a drain perhaps? More important to find out who did it and stop it happening again.

All this, and other occurrences, has left me feeling distinctly down this week.

Zillions of Games

2009-12-17T10:47:00.002Z

Back in October I obtained a CD from Zillions of Games which I installed on my computer. It enables one to play many different board games.

I've only just got round to making use of it to get back into the swing of playing chess. I was intending to join the Hastings Chess Club, but don't feel that my playing is up to the necessary level. Not that I've ever been much good.

It is possible to download many other games from Zillions. Circular Chess is a variant I particularly like, having played it at the annual championship in Lincoln. Zillions has three realisations of Circular Chess that I have downloaded, and so far have tried one of these. I lost against the computer, but at least the game went to 40 moves.

Recycling, Swimming and Quizzing

2009-12-11T23:39:00.003Z

On Wednesday. finding I had an accumulation of empty glass jars to dispose of at the recycling point, which is in the car park of the leisure centre, I decided to combine this duty with a swim in the pool.

Despite resolving to go swimming regularly, and it now being free for pensioners like me, I'd not been there for several months. Apart from the bad weather, and sheer laziness, this is because the times one can go swimming and get a clear lane are limited. The only trouble with swimming in the afternoon is that it disturbs the digestion. If I'm going to swim regularly at that time I need to organise my meals to suit.

On Thursday evening I ran a quiz for the Hastings Humanists. Most of the questions were based on a similar quiz I held a few years ago in Leicester. Although I thought many of the questions were quite easy the scoring achieved was only around 1 in 4 or 1 in 5 correct on both occasions. But then it's easy being the quizmaster since you have all the answers written down. Next year, as a member suggested, we could ask people to bring their own questions, and everyone could have a go in turn at being the quizmaster.

Tuning in to TV again

2009-12-08T19:32:00.004Z

When I moved back to Hastings in December last year (2008) I brought a portable television with me which, in Leicester, received all the channels on an indoor aerial, but when I tried it out here I could get no reception at all. I put this down to the hills and high buildings all around. However, after tidying up and moving things around last week, I tried again today plugging the TV into the outdoor aerial and this time I got Channel 5 (though on Channel 7). All the other channels were still blank.

After consulting the handbook about how to tune in the TV, and some considerable pressing of buttons, now find I can access all the five main channels, though BBC 1 and 2 were the most difficult to locate. Now I shall have to look at the programme schedules to see if there is anything worth watching.

Article on Mixed Quaternary Symmetry

2009-12-07T19:48:00.004Z

I've completed an article "On Mixed Quaternary Symmetry in Knight's Tours" which John Beasley has accepted for the next issue of Variant Chess. It follows up the work by Ernest Bergholt written in the form of memoranda sent to H. J. R. Murray in 1918 but not published until 2001 in The Games and Puzzles Journal #18.

It is only possible to include a summary of my results in the article, and I will be putting diagrams of all the tours onto my mayhematics website. The idea of mixed quaternary symmetry is to produce tours on the 8 by 8 and 12 by 12 boards that show a combination of direct (reflective) and oblique (rotative) quaternary symmetries, since tours fully in oblique quaternary are not possible on these boards, though they are possible on the 6 by 6 and 10 by 10 boards. Tours in direct quaternary symmetry are not possible on any boards, though pseudotours with this symmetry formed of two or more superimposed circuits are.

Where my treatment differs from that of Bergholt and Murray is in separating out the moves, such as the eight corner moves, that show octonary symmetry. Such moves can be regarded as part of either the direct or oblique sets of moves, but it is not always clear to which of these sets they should be assigned.

Cloud Scapes

2009-12-03T17:47:00.005Z

We have had beautiful cloud-scapes over the sea today. I went out in the morning to deliver some notices about the next Hastings Humanists meeting, and walked as far as the Bo-Peep Pub, but unfortunately forgot to take my camera. There were also some seagulls abligingly posed on the promenade railings, but no doubt they will be there to be photographed some other time. In the afternoon I remembered to take the camera. The chosen photo showing the outline of Beachy Head is almost of painterly effect. Earlier in the day the same view was clear enough to show the light reflecting off the white buildings of Eastbourne, and the clouds were bright and all shades of grey.

December is Here, or has it Gone?

2009-12-02T18:42:00.004Z

Our tree has now lost all its leaves, but still has a couple of plastic bags tangled in its twigs. This is now back to the way it was when I moved here in December last year.

An invitation has just come through the door "to view proposals for a new development at The College of the Holy Child Jesus" which is the building behind the tree. "Proposals include conversion of the historic buildings into residences, additional new residential development, a new open space facility and enhamced landscaping." The exhibition is open Friday 11th December (1 - 8 pm) and Saturday 12th December (10 am - 1 pm).

I suppose it is still December, and I haven't dropped off into a coma for a month? The date according to the read-out on my BT phone now says it is "Jan 2"!

Seeing the Sights in London

2009-11-25T09:28:00.005Z

I'm still feeling rather tired after a visit to London yesterday. The main purpose of the visit was to attend the lecture on "Darwin and God" at Westminster Abbey to mark the publication of Origin of Species on 24 November 1859. A report on the lecture will appear on the Hastings Humanists blog. The free lecture also provided an opportunity to see the interior of the Abbey without paying the £15 entrance fee that is now charged.

In a way the Abbey is as much of a national mausoleum as a church. The memorial to Isaac Newton is in a prominent position on the choir screen at the end of the Nave, and slabs marking the burial places of Charles Darwin and John Herschel are nearby in the left aisle. Poets' corner I didn't get to see. Religious symbols, like crucifixes, that one would see in catholic churches were not prominent. Perhaps one day, when the old superstitions have died away, it will become a shrine to the development of rational ideas.

I also passed some of the time with a visit to the Cabinet War Rooms, the bunkers from which the strategy was directed during the second world war. It now includes an extensive Churchill Museum, but I feel that this gives rather too much of bias to the presentation, placing too much emphasis on the one man, and detracts from the claustrophobic and intensely focused atmosphere of the War Rooms. Much more memorabilia of the other cabinet members and leaders of the armed forces would give it greater authenticity.

I also went down Craven Street, by Charing Cross station, with the idea of visiting Benjamin Franklin's house, but it proved to be closed on Tuesdays. The big wheel, the London Eye, was also a temptation but I think I'll leave that to a clearer and less windy day.

Falling Leaves and Litter

2009-11-17T10:49:00.004Z

Our tree is now rapidly losing its leaves. Some of the other trees have already lost them all. They are forming piles in on the pavements and in our garden area, blown there by the wind.

There is a supermarket plastic bag caught in the upper branches of the tree that has been there since last year. There are also large lumps of light polystyrene plastic that have been blowing down the hill and cluttering the place up. Where they have come from I don't know. Probably some black waste bag that broke open.

Someone, presumably in one of our flats here, has left an old door-frame in the front garden. It has been there several weeks. It will probably be up to me to arrange for it to be taken away. More recently someone has also left some bits of wood from carpentry work lying about, still with nails sticking out of them. I'd have thought any competent carpenter would know to remove the nails and dsipose of the waste safely. I find such carelessness annoying, especially when it's left to others, i.e. me, to tidy up.

Weather for Sea Gulls

2009-11-14T19:35:00.004Z

I took some photos from the promenade trying to give an idea of the heavy seas blown up by the high winds we have had since Thursday Evening. Static photos however cannot compare with a motion picture or the real experience. The sea gulls at least seem to enjoy the gales, perhaps they bring in some fish, but my impression is that the gulls simply like being in the element for which they have evolved to survive. A phrase I claim to have originated is that "Beauty is in the eye of the survivor".

Light and Dark

2009-11-09T20:46:00.004Z

This is the last photo from my walk that I'll be publishing for now. I thought the contrast between the darkness of the foreground and the sunlit scene of the reservoir beyond was striking. It can obviously be taken as a metaphorical image of someone looking out from a world of darkness, depression or imprisonment to an unattainable world of enlightenment, happiness or freedom beyond. Not that that's my frame of mind I should add!

I've been reading the book The Age of Wonder by Richard Holmes about science at the end of the 18th century when Joseph Banks, William Herschel and Humphrey Davy were active, and also The Lunar Men by Jenny Uglow, about the group that included Erasmus Darwin, Joseph Priestley, James Watt and others. Both reproduce paintings by Joseph Wright. I saw these, by chance, when I was in Derby a year or so ago and happened to pass time by visiting the City Museum, which has a whole room devoted to his paintings. Holmes writes that "Wright became a dramatic painter of experimental and laboratory scenes ... The calm, glowing light of reason is surrounded by the intense, psychological chiaroscuro associated with Georges de la Tour." I'm not sure that I entirely go along with this interpretation, but Wright's treatment of light is certainly striking.

A Tangled Bank

2009-11-07T19:23:00.004Z

This is another of the photos I took on my walk through Ecclesbourne Glen last month. It makes me think of the famous final passage in Origin of Species in which Charles Darwin writes "It is interesting to contemplate an entangled bank, clothed with many plants of many kinds, with birds singing on the bushes, with various insects flitting about, and with worms crawling through the damp earth, and to reflect that these elaborately constructed forms, so different from each other, and dependent on each other in so complex a manner, have all been produced by laws acting around us." And he goes on to expound in brief the thesis of evolution by natural selection.

There have been some beautiful sky scapes visible on the sea front over the last few days, particularly on Friday mid-day where there were extensive cumulus clouds out over the sea, silvered with sunlight and in numerous shades of grey, and this afternoon when, looking towards Beachy Head the sun's rays were shining down through the clouds. Until I first saw this effect some years ago I had assumed that artists paintings of sunlight as rays pushing through the clouds were just a matter of artistic convention; but they really were trying to capture the reality. Alas on both occasions I went out without my camera. I must try to carry it more regularly.

Tidying Up

2009-11-01T19:14:00.003Z

Tidying up did cheer me up a bit. A bit more progress on sorting my knight's tour material might help. The problem is that I keep changing my mind about what is the optimal method of arrangement. The way it is going seems to be to place emphasis on the different types of symmetry rather than on the board shapes. Thus instead of having a section on rectangular boards it seems better to classify rectangular tours across several sections according to their symmetry, and whether closed or open.

I tried switching on one of my convection heaters last week but it produced too much smell of burning dust. So today I took it all to pieces and cleaned it internally. I'm sure it could be made to come apart more easily. So many screws to take out, and so many pieces, like the wheels, to remove before the actual bodywork could be opened to give access to the oil-filled radiator! Fortunately it all fitted back together again and it is now working OK without the smell. It was all a bit like playing with the Meccano that I used to enjoy as a boy.

There is a central heating system and radiators, which came with the flat, but I'm not at all certain how that works. I use it to provide hot water for washing, but hesitate to use it for the radiators, since I'm not sure how much gas it is likely to use. I expect a cold spell will be needed to stimulate me to try it out.

Autumnal Attitudes

2009-10-25T22:57:00.005Z

With the putting back of the clocks I'm feeling rather depressed and autumnal. So I thought another photo of my favourite tree would be appropriate to mark the passing of the seasons. Its leaves are distinctly yellowing and thinning out, but at least the sun was shining which prompted me to take the photo.

I seem to be getting more and more buried in papers. My solution to depression is usually to tidy things up, but I seem to have been tidying things up for years without much result.

Since I installed the new version of P C Guard on my computer everything seems to have slowed down considerably. I suppose it is checking everything more thoroughly behind the scenes, but more probably its just dithering about. It also seems to decide to make virus scans always just as I'm about to switch off. I suppose everyone has got to change over to Windows 7 next.

Friends and "Friends"

2009-10-18T21:38:00.005+01:00

I've been getting a lot of requests on Facebook for people to be Friends, although many of them I've never met. However I recognise many of their names, mostly from the chess and puzzle world, and some I've corresponded with in the past when I was producing my magazines like Chessics and Games and Puzzles Journal. Other names I don't recognise, but usually they are Friends of Friends. After some hesitation I've now decided to accept most of these requests. To keep things in order I've classified most of them as "Chessic Friends" to avoid getting them mixed up with Friends I've actually met from Hastings or Leicester.

Another Friend who has contacted me is an old school friend who was at St Olaves Grammar School in the 1950s. That is Russ Stanfield. He is the only person from that period that I have encountered. I joined the Old Olavians a few years ago and went to one of their reunions, held at the new school buildings in Orpington, but there was no-one there from the same time. They would all now be approaching 70, if they have survived.

I intended to go to Hastings Pier on Saturday to join the demonstration for the Council to do something about renovating it, but when I looked at the clock it was past twelve, and when I arrived there was no-one about. I did manage to go out in the evening to see the bonfire and fireworks display on the beach. It was rather noisy, and I'm not sure what it was celebrating, but it was colourful.

DNA folds into a 3D Wazir Tour!

2009-10-11T19:29:00.004+01:00

According to a recent article in Science Daily, or at least the illustration accompanying it, DNA folds into a 3D wazir tour, similar to the 2D examples shown in my drawing alongside. These fractal-type diagrams occur at the end of a section of my Knight's Tour Notes website on Wazir Tours. For those not familiar with the terminology, a "wazir" is a chess piece that moves just to the adjacent square, like a single-step rook, or as in a king's non-diagonal move. A tour of course is a journey or path that visits all the squares of the board once only, without backtracking over any squares already visited.

Ecclesbourne Glen

2009-10-06T13:34:00.003+01:00

This photo is the one I took before the shadow photo. It is a view looking down into Ecclesbourne Glen. I walked down the hillside to enter the Glen via a gate at the bottom left. There are steps leading down that meet another set of steps going up the hill on the other side. At the bottom there is a narrow path leading down towards the sea. Whether it gives access to the beach there I don't know.

Casting a Strange Shadow

2009-10-01T20:15:00.003+01:00

Feeling the need for more exercise I decided on a long walk this afternoon and made my way along the seafront to the fishing boats and climbed the steps up to the East Hill and along the cliff edge to Ecclesbourne Glen. There I followed the further steps down into the glen and up the other side. The photo above was taken on my way down the steps into the glen. I was surprised to find, when I put the image up on the computer, that my shadow seemed to have grown some sort of catlike tail! Once up the other side I took the route through the woods, ending up at Barley Lane. I found I'd taken 33 photos by the time I got back home. The sun was very bright in my eyes on the way back. On the way through the glen I met a man coming the other way, from Fairlight, and chatted to him briefly about the steps being rather uneven. On the way back our paths crossed again. He said he had come all that way just for his fish and chips!

The Attraction of Puzzles

2009-09-25T14:30:00.004+01:00

I enjoy doing the puzzles in the newspapers I buy, both the numerical ones like Sudoku or Kakuro or the letter ones like Crosswords or the Code type where numbers stand for letters, though the latter aren't usually very tricky. In fact the puzzles provide the main reason that I buy papers at all these days.

By far and away my favourite crosswords are those composed hy Araucaria in the Guardian. Unfortunately the other composers in the Guardian never seem to reach the same standard. Not only are his clues always fair, so that once you have found a solution you can tell with reasonable certainty that you have found the correct solution, but he also covers a wide range of knowledge (which is often exhibited in themed puzzles) and is also often humorous.

It is annoying however when puzzles are misprinted, or mistakenly set, so that they have no solution or more than one. I wrote to the Radio Times last week to complain that in two recent issues their Mandali puzzle, which is a sort of maze, had two numerical solutions. They were kind enough to reply and apologise. Unfortunately the Mandali puzzle in this week's issue has at least six solutions! This is just carelessness.

The attraction I find in puzzles I think has to do with the fact that they are soluble problems. There are too many problems in real life that are insoluble and simply frustrating. The only viable approach to them I have concluded is step by step and little by little, and maybe a little amelioration can be achieved.

Cycling to Eastbourne

2009-09-22T21:17:00.005+01:00

Today the need for some exercise that I've been feeling for a while came to the fore and I decided to cycle to Eastbourne. I should have set out earlier but it took a while to persuade myself that it was better than lying around. The decider was that the sun was still shining at ten o'clock and it looked too fine a day to waste. Indeed it was a lovely day, the only drawback being the strong headwind on the outward stretch. I several times thought of stopping short, but once I reached Pevensey Bay it seemed, looking at the map, too short a distance left to call it off there. I went as far as Beachy Head, and had a meal at the cafe below the hill where the South Downs Way starts. Just to prove I did the trip, the photo is of Eastbourne pier taken on my way back. I arrived back at 6 pm, so it was four hours either way. Part of this slowness was due to the headwind on the way out, and due to taking some wrong turnings on the way back, trying to follow the cycle lane markings, and also choosing to walk the bike along the beach from Glyne Gap rather than cycle the heavily congested and polluted Bexhill Road. No doubt I'll be feeling a bit stiff in the legs and sunburnt on the head in the morning.

Autumn is Here

2009-09-18T20:26:00.004+01:00

I took this photo of my favourite tree as I went out for a walk along the front as far as the old bathing pool site at the end of Sea Road. I have been thinking of getting out on my bike and going perhaps as far as Eastbourne, but left it too late to do that today. It was a very sunny afternoon. The other pictures I took haven't come out very well probably because the light was too bright and I couldn't see clearly what I was focusing on. The leaves on the tree are starting to turn brown, and some of them may have been shed already. There are a lot of leaves from other trees blowing around.

When I turned on my computer and activated the PCGuard I got a message "Rps: The parameter is incorrect" with no further explanation. Checking it on Google I was led to download a thing called RegistryBooster costing about £20. Whether this does any good remains to be seen. It claims to have cleared up a lot of errors in the Registry, but whether they are really significant or just listed to impress I don't know. Perhaps I shouldn't be so cynical.
