Things are still not going well. I’m experiencing a lot more anxiety than I have for a long time and struggling to cope. I did watch some math YouTube videos today, however. Among them was one about the Banach-Tarski Paradox, which reminded me of a joke I read once: “I’ve got 99 problems, but Banach-Tarski is 198 of them.” (For the uninitiated, the Banach-Tarski Paradox concerns how a solid, such as a sphere, can be split into two perfect copies of itself. It’s pretty wild, and I didn’t fully understand the argument. I think I’m going to look for another video on the same topic.)
