Reminds me on a science fiction novel I read decades ago. I think it was Frederick Pohl's "Drunkard's Walk." I don't remember the plot, but the protagonist was a math professor at a future university where the classes were taught over the air and were very glitzy. The discussion of drunkards's walk, I think, had animation of a drunkard... There was also this ditty that was sung by a chorus during a number theory lecture (also supported by animation, of course)
Strike the twos and strike the threes The Sieve of Erotosthenes When the multiples sublime The numbers that are left are prime.
--- Maybe it is the way education should go. After all, I've never forgotten it! ;-)
