Sheldon's stair theory.wmv

Sheldon - You want to hear an interesting thing about stairs?
Leonard - Not really.
Sheldon - If the height of a single step is off by as little as 2mm most people will trip.
Leonard - I don't care. *pause* 2mm? That doesn't seem right.
Sheldon - No, it's true. I did a series of experiments when I was twelve. My father broke his clavicle.
