As part of an intro to kinetic theory I produced a movie of a single atom moving in a 1-D box, and advertised it as the most boring movie ever made.

Maybe they should have asked for directions sooner.

What is Van Gogh’s “Starry Night” actually about? There is an idea that it shows he understood turbulence, long before anyone else. But the truth is probably much simpler: he was fascinated by astronomy. So why does it look so odd? For an answer, bit.ly/43tkad4

The E8 one is a bit of a fiddle: it's wrong, but there are other shadow matter ideas. Also chameleon (variable mass particle) theories, but I'm not aware of any viable ones

Last week we had a departmental dark matter day. I gave the first speaker a copy of a slide I used at the first DM talk I gave in 1985 (transcribed from the original stone tablets), showing what I thought were all the viable ideas.
What a lot of progress we have made since then.

Almost certainly M51 was what inspired Van Gogh's "Starry Night". The first popular astronomy book showing M51 was Flammarion's "Astronomie" in 1889, the same year as Van Gogh painted it!
