Back to school: teaching an old dog new tricks
I've determined that my early sixties is as good a time as any to begin an intensive self-study of mathematics! I haven't decided on a specific area of focus yet (what's the rush!), but I'm leaning toward data science, machine learning and artificial intelligence.

Computing Pi with Colliding Blocks
A friend sent me the following videos that I found beautiful from a math & physics perspective.
