Here I explain that the icosidodecahedron, this beautiful polyhedron with 30 vertices, is the shadow of a shape in 6 dimensions with 60 vertices - and also the slice of a shape in 4d with 120 vertices, which is the shadow of a more shape in 8d with 240 vertices!
30, 60, 120, 240.
Let me briefly sketch the ideas here.

@bibliolater nice tool! thank you for sharing.
There is a workshop at the Fields Institute right now. I estimate maybe 15% of people attending are masking. Appeals by CMOH for voluntary masking absolutely don't register (most people aren't even aware of them).
This isn't surprising in the least. Outsourcing public health policy to individual choices by people never worked and never will. Moore knows this but chooses to do nothing.

There's a good chance your at-home Covid-19 tests are past the expiration date on the box. Don't toss them; they're good well past that date. Here's why the expiration date is wrong and how to tell if yours is still good

Zombie fires and soaring temperatures: What happens when it gets to 100ºF in Siberia.
Satellite data shows that blazes swept through nearly 12 million acres in the Siberian Arctic between 2019 and 2020, resulting in unprecedented carbon dioxide emissions.

The pandemic has been one giant example of Brandolini’s law. Imagine if we didn’t have to spend so much time debunking:
- kids don’t get covid
- kids only get very mild covid
- lockdowns will cause waves of kid suicides
- covid doesn’t transmit in schools
- covid is mild
- covid is over
- covid is not airborne
- respirators are overkill
- ‘immunity debt’
- masks cause infections
How much safer would we be?

I might like it even better than the classic version by Judy Garland.
God put me on this earth to accomplish a certain number of things. Right now I am so far behind that I will never die.

The world is so dreadfully managed, one hardly knows to whom to complain.

For every complex problem, there is a solution that is simple, neat, and wrong.

One of #Wordle Bot's favorite starting words really came though today. Just 2 possibilities left after the first guess. Of course I guessed the wrong one first.
