      There’s no Nobel price for mathematics, but I can accept the one for peace instead.

    I’d prefer an alternative definition that starts with the base case ¡0! = 1, and then for n > 0 we define ¡n! = n * ¡(n-1)!

  It’s the same calculation but you also take a shot of vodka for all integers less than n but greater than 0
