CORRECTIONS
3.01 - the correct form of the area of a circle is of course pi x R^2, not 2 x pi x R^2. If only integration were more straightforward. (Thanks simonlitvinskii1898 for spotting it!)

For my terrible visualisation I pulled the equations from the OpenAI paper section 3.1 and used Claude to build a visualisation. The angular moment values are unitless and basically meaningless as OpenAI didn't give any and I've just pulled the max value swirling around in the visualisation simulation. But I thought it added a valuable point that we care about the max speed in the middle, and that changes with tau.

Thanks to a few people for pointing out my dry-wipe pseudo-code for Bubble Sort is a bit out. where it says "if i [greater than] i+1" it should read "if L[I] [greater than] L[i+1]”. Also this correction should use the 'greater than' symbol but YouTube won't let me put them in.

Here is the full Tennis Challenge puzzle:

Alice, an amateur tennis player, has just joined a tennis club. As a welcome, the head coach Jenny decided to give her a challenge - Alice will play 3 games against Jenny and another club member Carla alternatively, and she needs to win two consecutive games to win the challenge. The coach allowed Alice to pick the order in which she would like to play those games - either Jenny-Carla-Jenny, or Carla-Jenny-Carla. Everyone knows that the coach is the best player in the club.

Which order should Alice choose?
