Post A pythagorean catastrophe!
This forum has been relatively quiet recently.So I have decided to involve you all in something interesting.Here is the problem:
Prove that \sqrt{2} is irrational without resorting to proof by contradiction.

I have recently proved it without employing reductio-ad absurdum.Anyone else wants to try?
Post your solutions and your comments in reply to this post.

P.S.I will disclose my proof eventually!
