Math and physics explain the anguish of a golf ball that zings around the rim of the hole instead of falling in.

If you drop an object, it will fall. It's a motion that we’ve all seen hundreds of times. We’ve also all seen plenty of the moon, which makes one complete orbit around our planet every 27.3 days (as ...

Let’s consider GW150914, the first binary black hole merger detected via gravitational waves. The final black hole formed during the merger is 60 times the mass of the Sun, which means that its size ...

Our motion perception is remarkably well tuned to detect small changes in speed and direction. For example, soccer goalkeepers need to precisely judge the speed, direction, and curvature of an ...
