What is math's most famous proof? It's certainly debatable, but one candidate is Euclid's 300 BC proof of the infinitude of primes. Famously, it was done by contradiction, making it an early example of such a powerful technique. But what if I told you that's a lie? That Euclid's proof wasn't by contradiction? I'm telling you: Euclid's proof wasn't by contradiction. #maths #mathematics
