I can't help myself. I have to say something about this awesome water slide as seen on io9. You really should check out the io9 article - an interesting read. But for me, let me see if I can estimate ...

The mechanics of friction may seem the stuff of high-school physics, but only now are some aspects of the problem being understood. A spinning coin is the subject of a new exploration of frictional ...
