What’s the smallest lunar object a phone camera lens could resolve from Earth? Here’s what the physics of light tells us about shooting the moon.

To see if those videos of people conjuring liquid without any external power actually hold water, you’ll need physics—and a straw.

Schools adapted to remote learning, but students also got used to seeking easy answers instead of real understanding.

A deep dive into the science of staying alive underwater.

If you want to attain high speeds without getting airborne, it helps to know a little something about friction.

Global warming is melting Earth’s glaciers, which is moving vast amounts of water—maybe enough to affect the planet’s rotation.

It takes a lot of energy to jump over cliffs and hurl rocks at the speed of sound—and that means eating at superhero capacity.

Lidar measures distance by bouncing light off of objects—but there’s more to how light travels in the first place.

There was a flurry of discussion recently on campus about "critical thinking," and how we sell that idea to prospective and current students. This was prompted by a recent report arguing for the importance of the humanities and social sciences (which I found really frustrating in ways that are neither surprising nor important for this post).

The internet thinks it has discovered the secret to fuel-free perpetual motion. Physics knows better.
