Maths is fun

Last week I went into the PhD office across the hall. On the whiteboard was a geometrical proof for the very famous Pythagoras' theorem . After some thinkg, I added another proof for fun. This week I noticed there is now five proofs on the wall (one using complex numbers). And who says maths students don't know how to have fun?

Interestingly, Pythagoras' theorem is the most proven theorem in mathematics (it has over a three hundred proofs using mathematics from all areas - one of these proofs was done by James Garfield who was, very briefly, a US president). Hence, we will have plenty of fun for years to come...now if only I could stop procrastinating and do some actual meaningful work.
