really interesting video.

  This YT link is to a recent (2019) video on the Numberphile channel with Matt Parker as presenter, just so people know what level of quality to expect (14m26s runtime). And, yeah, that's one of my favorites in the STEM genre. I can't wait until my son (now nine) is ready to watch along with me.
