Had a Beef Wellington the other night. Bitterly disappointed. It was as tough as old boots.
One Day in the Life of Ivan Denisovich, by Solzhenitsyn, based on his experiences in a Soviet forced labour camp in the 1950s.Â
The most chilling quote so far
âPrisoners are not allowed clocksâ.

A friend captured this view from the top of Cat Bells at 09:27 this morning.
Disasterâs bound to strike

A pelican goes into a bar and says, Can I pay for last night? The barman looks at him and says, Youâve got a massive bill.
A bad hangover leaves you confused the next day but a worse one lasts until the daze after tomorrow.
Seated in a chair, raise your right foot from the ground and start moving it in a clockwise circle. While continuing to move your right foot, extend your right for finger and draw a figure 6 in the air. What happens?Â
See here for a YouTube video about this surprising effect.
It appears on lots of web sites, often under the title 'How smart is your right foot?' but I hadn't come across it before.
Iâm reading a book about blotting paper. Very absorbing.
Iâve just bought 12 baby polyanthus plants via Amazon. When they flower they will be an assortment of 6 colours and Iâm assuming there will be 2 plants of each colour. But at the moment they all look pretty much the same.
Iâm planning to give 4 plants to a friend. Given we will be picking the 4 at randomâŚ
What is the probability that my friend will receive 4 plants all different colours?
Itâs very beautiful and resembles frost crystals, or perhaps some kind of mineral formation (although I suppose ice is a mineral, thinking about it). But what you see here is a fungus, the âurchin earthfan). My brother took the photograph.
Thereâs a good article about this fungus here

What colour leaves you in the dark? Light blew.
Tonight when I paid my bar bill I held the card reader to my right nostril, and my Apple Watch to the left. Everything went through. So I literally paid through the nose.
New TV series about falconry. Britainâs got talons.
What colour leaves you abandoned on a desert island?
Maroon.
"By their very nature bureaucracies have no conscience, no memory, and no mind."
I've been trying to remember this quote. I found it striking when first told it but I'd partly forgotten it so it's taken a while to track down. Itâs by the American anthropologist Edward T. Hall, although I still canât find where he wrote or said it
You can only fight it for so long.
Eventually you can betcha,
The System will getcha.
I read today in the New Scientist about âMiracle Berriesâ, seen below. Eat one and for twenty minutes or so sour things will taste sweet. Isnât that remarkable?
A link to the NS article is below, and there is also information on Wikipedia.
Naturally I want to grow some and the seeds are on their way.

The origin is Old Norse hus-thing, âhouse meetingâ, and referred to an assembly of the people in the household of a noble man or woman. Over time its meaning has come to mean a platform for politicians to make speeches from.
The thing element just meant assembly and survives today in the name of the Icelandic supreme parliament, the AlÞingi.
Old English also had folk-moot, âfolk meetingâ. Here moot is the same as in the phrase âa moot pointâ = a point to be discussed and also found in moot hall. Folkmoot survives but mainly in historical contexts.
A delegation of villagers sought an audience with the abbot.
Reverend sir, they asked; when is the best time to plant a tree?
Ten years ago, replied the abbot.
Or sooner if possible.
You have no means of recording the numbers as they are read, and although you are quite good at mental arithmetic you only have an average memory and remembering the entire list of numbers as they were read out is beyond you.
What is the best way to identify the missing number?
A few days ago I wrote about an elegant proof that a regular dodecahedrons has 4 diagonals that all intersect at a point other than the centre of the polygon, see https://learn1.open.ac.uk/mod/oublog/viewpost.php?post=248909
Since then I have found a paper by Poonen and Rubenstein [1] in which they completely solve the problem of concurrent diagonals in regular polygons. They prove several interesting facts, including:
If the number of sides is odd there can never be 3 concurrent diagonals.
The smallest number of sides that allow 3 diagonals to meet at a point other than the centre is eight, for diagonals twelve sides are needed, and for 5 concurrent diagonals eighteen sides.
To get more than 5 diagonals meeting at a point other than the centre we need to go to thirty sides. The regular triacontagon has sets of 6 and 7 concurrent diagonals.
And then suprisingly it stops. No regular polygon, however many sides it has, can have eight or more diagonals intersecting at a point other than the centre.
