How long is a piece of string?

How long is a piece of string? It sounds like a ridiculous question... but it isn't. This hour long journey to find out the length of a certain piece of string will blow your mind. This trip takes you from the classical to the quantum and leaves you with more questions than answers. Easily one of the best episodes from BBC's Horizon. I know that an hour of your time is a lot to ask for, but believe me, it's worth it.
