Tessellation

A version of this tessellation appeared here a little over a year ago - on Monday 20th September, 2010. I came across it again recently and prepared a blue-on-blue version. I thought I'd post it to see how it looked within the colour scheme of this blog. Perhaps more will follow.

St Peter's 'Square'

This is a scan of an old photograph taken in Vatican City in 1989. I've been there twice and on both occasions have wondered why St Peter's Square is circular - or perhaps more accurately - oval. (See: Google Maps.) Either way, it is curved as the photograph shows. It is certainly not a square. In fact, from above, the whole space in front of St Peter's Basilica is somewhat keyhole-shaped. Could this be a deliberate reference to St Peter being promised the keys of the kingdom of Heaven (Matthew 16:18-19)?

Neutrino Joke

Recently some work done in association with CERN has suggested that Neutrinos might have been observed traveling faster than light (See: The Guardian, 22nd September 2011). Amongst other things, this tends to turn the whole idea of causality - or cause and effect - on its head. Hence, a geek joke currently doing the rounds goes:

The bartender says 'we don't serve neutrinos'.
A neutrino walks into a bar.

Barcode - 3

Here is another barcode based upon the name of this blog. This time it is a 'Code 16k' barcode. If you want to find out more about this and other types of barcode, you could visit Neodynamic.

11-11-11

Not only is today's date a palindrome (in the way I have chosen to write it) but all the numbers are also the same. This, so far as I can tell, only happens once every hundred years. Something unique in most people's lifetime is surely worth noting.

Of course, today is also Armistice Day commemorating the signing at the "eleventh hour of the eleventh day of the eleventh month" in 1918 of the armistice which officially brought World War I to an end.

(I am, in fact, writing this entry on 27th March 2011 and scheduling it to appear on 11th November, lest I forget. I wonder whether, when we get closer to '11-11-11', somebody will come out with some mystical significance for this date. Perhaps it will be the date for the end of the world … again.)

Caught in mid-air

I was wandering through Google Maps the other day, following a railway line across parts of London in which I used to live and found that an aeroplane had been photographed in mid-air in the region of Seven Sisters Road, South Tottenham.


My guess is that the plane is one of the newer Boeing 737s belonging to Japan Airlines. Furthermore, this picture must have been taken fairly recently since this livery appears to have been adopted only this year.

Another observation about the clocks changing

I came across this intriguing thought while listening to the radio the Saturday morning before the clocks went back. Somebody contacted the show to say that they had been born at 1.50am the night the clocks went back. That is, just ten minutes before the clocks were put back. That meant that an hour later there was another 1.50am. How does one distinguish between the two? There could be two people each born at a different 1.50am and so differ in age by an hour.

That the clocks change in the middle of the night is surely to minimise confusion where possible. However, there are things that will nevertheless happen during that hour even though most people will be asleep.

While on the question of there being two of all the times between 1am and 2am of the day the clocks go back, on the day the clocks go forward there are no times between 2am and 3am. Nobody has ever been born at, say, 2.50am on such days.
