I don't like that proof...
I'm not ashamed of it - I love maths. Well more specificially I love numbers. Ever since I was a kid, I've loved asking questions about numbers. I remember from any early age being irked by the fact that 2 is the only even prime number. Of course, my adult mind can rationalise that even means "is divisible by 2" and hence 2 is no different to any other prime number - the difference is a semantic one because we've given a label to the concept "divisible by 2". It's trivial, of course, that every prime is the only prime divisible by itself. There are a lot of prime numbers. An awful lot. In fact, there's an infinity of them. Even at school we were taught an easy proof that there are an infinite number of prime numbers. It went like this... Presume there's a largest prime number and call it P. Take all of the prime numbers up-to and including P and multiply them together and add one. Voila - another prime which is bigger than P. Hence a...
