That sounds pretty awesome. We never got quite *that* far. I think our 
experiments weren't so precise we had to worry about anything more funky 
than the total rolling friction of the cars. We didn't calculate the 
deformation of the track or anything like that.

Altho I do remember that at one time I knew how to calculate the speed of 
light given the mass and charge of an electron, and why it worked that way.
