Today I watched part of an interesting video by 3blue1brown about the surface area of a sphere. I had a lot of trouble concentrating on it, though. Near the end it began to require more participation from the viewer, and I decided to save the rest for later. There’s some hope underlying that, I guess.
Persistence is a valuable tool.
the surface area of a sphere does spring eternal, I believe.
Indeed. Quite a bit more eternal than anything in the human breast, I’d say.
