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 ...

Back on Sunday, I devoted a "Football Physics" post to talking about erratic bouncing and an amazing rugby play where a ball popped up high at just the right moment. That's the sort of play that ...

The list of informal, weird AI benchmarks keeps growing. Well, simulating a bouncing ball is a classic programming challenge. Accurate simulations incorporate collision detection algorithms, which try ...

A physics demonstration shows how bouncing balls can appear to keep moving endlessly, explaining the energy transfer and motion behind the effect. Quote of the day by Albert Einstein: 'The only real ...
