I’ve seen many street performers in my time, mainly musicians and dancers. Take, for example, this accordion player I saw while in France two years ago.
Now replace that accordion player with someone performing math tricks. Yes, math tricks. This was not my idea. It is, however, an excellent one, especially given the general public’s simultaneous fear and amazement at math and those who are good at it. I just need to brush up on some math tricks to live to up to the title of mathemagician.
Math busking may not be on the level of writing proofs for food, and it may not even provide money for food, but it would be fun, right?
