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 ...

Gravity doesn’t discriminate. An experiment in orbit has confirmed, with precision a hundred times greater than previous efforts, that everything falls the same way under the influence of gravity. The ...

It’s been demonstrated since the 1500s that, when falling toward a certain body, objects fall at the same rate. Everyone from Galileo in Pisa to David Scott on the moon demonstrated that. But what if ...

Centuries before anyone pointed a telescope at the sky, Isaac Newton figured out how gravity works. He showed that any object with mass pulls on every other object—a result that explained falling ...

Newton's laws of motion predict that an object will fall when its centre-of-mass lies beyond its base of support. But how does your brain know whether the tower will fall or not? Scientists in Germany ...
