This is wonderful!
I don’t know the British comedian Dave Gorman, but this bit on perfect numbers makes me like him. He explains what a “perfect number” is in the sketch, but you can also read about those weird numbers here. When you look at Euclid’s formula for generating even perfect numbers, which shows a one-to-one correspondence with primes, then you realize instantly that there is an infinite number of perfect numbers. But I digress. The skit:
Gorman studied math (or rather “maths,” a term that I find jarring) at Manchester University, where both Matthew Cobb and Brian Cox teach.
