Sometimes a cat will fall out of a window or balcony—a byproduct, no doubt, of a cat doing cat things. If you have a house cat, your feline's propensity for aerial shenanigans probably doesn't worry ...

For all objects at height – including humans – the focus always should be on preventing things from falling rather than on catching objects, or on limiting the damage after they fall. Dropped objects ...

Falling objects injured three different people in three separate incidents I recently investigated. The common thread: unsecured objects above the victims’ heads. As in any falling-object case, most ...

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 ...

In New York City in 2018, a cat reportedly fell from the window of a 32nd-floor apartment onto hard asphalt—and survived. After a two-day stay at the vet, who treated a collapsed lung and broken teeth ...

This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

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 ...

If you want to build a rocket with a bold new design, you have to have a way to test its structural integrity without installing an engine. You don’t have a wind tunnel, but you’re not ready to ...

How gravity causes a perfectly spherical ball to roll down an inclined plane is part of elementary school physics canon. But the world is messier than a textbook. Scientists have sought to ...
