Ok, here is an interesting thing. You know steps in old buildings like castles and shit, where there's a curve worn into the leading edge from all the centuries of feet? That curves represents the probability distribution of where a foot is most likely to step, and ends up, unsurprisingly, as a bell curve.
At some point I'll take a photo of the thing outside my flat where people have been sitting for about 500 years. People's arses are surprisingly wearing.
Would you be interested in knowing that the actual length of any river is about three times longer than the straight line joining the source to the end then? That's Maths too.
Add THE VETOES to your myspace friends!!! Pretty please :D
