Radical Cheat and Playful Mathematics

One of my favourite professors in university taught a second-year course on solving differential equations. He would bounce into class, silver hair flying, making us feel like it was our lucky day to be studying math on a beautiful day in that stuffy old classroom. I still remember how he would preface the problems we would solve with: “Alright, so that’s the game! Let’s play the game.” And off we would go. After all these years, this phrase stuck with me – admittedly, more than the mathematics I learned during the course. Maybe he was referring to the fact that we were working with “toy problems,” as other professors would say, suggesting that they had little resemblance to the problems mathematicians actually work on day to day; I like to think, though, that he was talking about how mathematics itself can be a form of play.
