Accordion to research, 9 out of 10 people don't notice when you replace words with random musical instruments.

A Strange Game

Visible to anyone in the world

Every day a group of friends play a strange game. Everyone writes their name on a slip of paper, folds it, and drops it into a hat. The slips are thoroughly shaken up, and then each player pulls a slip out of the hat. Anyone who draws a slip with their own name on wins a prize.

My question is: over a long series of games, what is the average number of players per game who win a prize?

Chain fountain

Edited by Richard Walker, Tuesday, 23 Nov 2021, 12:37

Inspired by Steve Mould's videos about the chanin fountain, I bought 5 m of 3.2 mm beaded roller pull chain and took it down the pub, where it was a big hit.

Lucked out

Visible to anyone in the world

When my groceries came today the supermarket had replaced an item costing Ā£12 with one costing Ā£30. So a good deal! I messaged a friend and said ā€œI lucked outā€. But then I wondered if I meant ā€œlucked inā€.

Well lucked out is indeed what I meant. Itā€™s an idiom for a fortunate event. But it is also an idiom for something happening that is unfortunate. So it can mean something and also the opposite, which is interesting.Ā 

There are words in English that behave the same way: for example ā€œcleaveā€ can mean cling to, but also separate from. And ā€œclipā€ can mean attach, but also cut off.

There is an interesting discussion hereĀ

PS Confusingly there is another idiom ā€œlucked inā€. And that is definitely good fortune.Ā

Dichromatism - edited

Visible to anyone in the world
Edited by Richard Walker, Monday, 15 Nov 2021, 23:07
Pumpkin seed oil has an intriguing and unusual optical property; it is dichomatic. A thin layer is coloured some shade of green but a thicker layer is a dark-reddish purple. When I heard about this from Steve Mold's YouTube piece The rare property of pumpkin seed oil - dichromatism, I bought some and took this photograph.



The camera has distorted the colour of the green area slightly; it is less yellow and more green that the photograph suggests, at least to my vision. EDIT here is another photo, that shows the two colours better.



From what I can gather the explanation is that a thin layer of pumpkin seed oil transmits significant amounts of blue, green, yellow and red light and the blue, green and yellow together dominate and are perceived as green. However once the layer gets more than 0.7 mm thick the blue, green and yellow are sharply attenuated and the transmitted light is nearly all red. I owe this information to the Wikepedia article on the topic at https://en.wikipedia.org/wiki/Dichromatism

Next week I'm going to try an Austrian salad dressing, pumpkin seed oil and cider vinegar.

More from Deep Dream

Visible to anyone in the world

I took the same snow scene as in my blogpost of 20 October and put it through the Deep Dream generator, but this time the transfornation was not based on a style image but instead on patterms the AI software has been trained to recognise. Here's the result, bizarre and vaguely disturbing, but very interesting.

Sapere aude

Visible to anyone in the world

Iā€™d never heard this before today but stumbled across it.

It originates with the Latin poet Horace, but was taken up by Immanuel Kant in response to the challenge: ā€œWhat is the Enlightenment?ā€ Usually itā€™s translated as ā€œDare to knowā€; the sapere part means ā€œTo knowā€ (think sapient pearwood in Terry Pratchett) and aude as in ā€œaudacityā€). In Latin word order didnā€™t matter (much); which is why it (misleadingly) looks like ā€œTo dare, knowā€ in English.Ā 

Thereā€™s the background. What do you think? Should we dare to know? What is the alternative?

Snow Scene

Visible to anyone in the world
Edited by Richard Walker, Saturday, 30 Oct 2021, 14:21
Here's a rather beautiful picture of a snow scene, in a style vaguely reminiscent of Seurat.


It wasn't painted however but computer generated, using the Google AI program Deep Dream at https://deepdreamgenerator.com/, with the style "Seurat", starting with the snow scene below, which I took a few years ago.



I hadn't heard of Deep Dream until today, but I found it absolutey fascinating to play with.

Trepanning

Visible to anyone in the world

Trepanning is an ancient (back to Bronze Age) surgical procedure (the earliest attested) that involves cutting a one inch or so circular hole through a person's cranium, to relieve pressure from a brain bleed, or perhaps to vent evil spirits, or for other for other ritual reasons. Thereā€™s a substantial body of archeological evidence for the practice,

But I canā€™t help thinking the patients (subjects?) would have found it tedious. They must have been bored out of their skulls.
