The above video was drawn to my attention by a friend. It is nice to know that there are people for whom the “Josephus problem” is not something related to the Testamonium Flavianum or the mention of James the brother of Jesus, but something with real world practical implications. Can you guess what the “Josephus problem” is in mathematics before watching the video, and why it is called that?
UPDATE: Jim Davila pointed out that there is an article in Popular Mechanics about this.
