Fold and Cut Theorem - Numberphile
Lynda free trial (try the typography stuff!!): http://www.lynda.com/numberphile Katie Steckles discusses the Fold and Cut Theorem - from A to Z. More links & stuff ...

I have a pair of scissors 'cause I want to talk about a piece of maths called the Fold and Cut Theorem. It's one of those things in maths where they just name it what it is. This first came to my attention when I was trying to cut a square hole in a piece of paper. So, like, my first instinct - as a person who cuts holes in paper - was to jab a hole and then cut round the edge of the square. But I thought, ok maybe there's an easier way to do this, and kind of my mathematical brain kicked in, and I realised that if I fold this in half like that, I can just cut along those three edges. Ok, I've roughly approximated the hole I was originally trying to draw. There's a square hole, and I guess like, the mathematician in me was like, "Can I do that more easily? ...
