Derek Muller explains Hilbert's Paradox of the Grand Hotel and how an infinite hotel can still run out of space.

If there's a hotel with infinite rooms, could it ever be completely full? Could you run out of space to put everyone? The surprising answer is yes -- this is important to know if you're the manager of the Hilbert Hotel. ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ References: Ewald, W., & Sieg, W. (2013).

On “How imaginary numbers were invented [video]”

I love Veritasium. Derek has done a number of videos that are awesome like this. The videos are great and educational, but he also manages to subtly weave in an almost spiritual subtext to them as well. For example, in this one, you learn about imaginary numbers in some cool ways, history, how awesome e^ix is, etc, but also this yen-yang balance between embracing not only what is real but taking a chance on what is imaginary. Some of my other favorites: - link - link - link to this video - link - link I think he’s going to lose the $10,000 bet on the car though.

On “What is the Axiom of Choice?”

Veritasium describes a similar situation (not the AOC); a hotel that has infinite rooms and what happens when an infinite number of buses each with an infinite number of guests pulls up. link to this video

On “The Shameful Decline of Scientific American”

…o much filler and dramatization to try to make it interesting, and the whole thing felt dumbed down compared to his usual content, for example 2, which is deeper and relatively information-dense. And there are channels like PBS Spacetime which go far, far beyond anything I’ve ever seen in any media aimed at a general audience 3. 1 link 2 link to this video 3 link…

Oh and if you’re asking about ways to prepare, I would just recommend watching tangentially related videos that will get you excited about the topic! Here’s an example: link to this video
