A physics demonstration shows how bouncing balls can appear to keep moving endlessly, explaining the energy transfer and ...

Back in the fall of 1989, I was a freshman at Williams College, and one Monday night that fall there was some sort of problem with the cable TV in our dorm, so a bunch of us went next door to watch ...

Researchers have carried out detailed molecular dynamics simulations to understand the motion of intriguingly ball-shaped C60 bucky balls on metal surfaces. The shape suggests several interesting ...

Model: This is some type of representation (conceptual, mathematical, physical, computational) of a real object. Example: a model of a bouncing ball would produce results that agree with a real ...
