specifically this one is interesting, crowdfunded an island! I dreamt about exactly this around the same time - but this guy actually did it! :D

"it doesn't have to work for very long" design doesn't get much shorter time scale than that. (Barring fusion / fission but you shouldn't do that in the garage)

I mean, sure, Helen Keller accomplished a lot. But crazy to me that no one talks about the deafbling woman who validated tactile signing almost 50 years before her.

It was basically that episode of South Park where Butters becomes a pimp and it almost cost FDR his career.

For example, the tiny big number like 3^^^^3 has ~around 3^^^^3 digits in basically any reasonable base: base-10, base-16, base-64k, base-1m. You can’t express its length in a regular form. For contrast, the “trillion trillion trillion trillion trillion trillion trillion trillion trillion trillions” has only 21 digits in base-1m.

Another example is Moser:

N in a triangle is N^N. So e.g. N in two triangles would be (N^N)^(N^N).

N in a square is N in N triangles.

N in a pentagon is N in N squares.

Mega is 2 in a pentagon, i.e. 2 in two squares, or 2 in two triangles and a square, or 256 in a square, or 256 in 256 triangles. Pretty big, huh?

Moser is 2 in a Mega-gon.
