Step one: Trick or treat. Step two: Get out your bomb calorimeter. (Yes, that is a real thing.)

You can’t block electromagnetic waves, but there’s still a way to keep electronic devices like cell phones in stealth mode.

To figure it out, you’ll need two similar feats of superhero strength and a little bit of physics.

Although radiation sounds scary, it isn’t necessarily harmful. Here’s what to know about the four types.

It seems impossible, but there’s a way to cool things off without tapping into a fuel source. (Hint: It involves outer space.)

In the physics of water displacement, the answer isn’t always intuitive.

How much energy would it take to fuel a wave that you can shred like Kelly Slater? Here’s the math.

Electric vehicles are increasingly popular, so it’s time to talk about regenerative braking—and all the other ways you can stop a vehicle.

The best pitchers in baseball are known for their speed. But if you don’t have a fast arm, you may still have a chance.

The “Monty Hall problem” is a classic example of how games of chance can have surprising results. Here’s a fun way to model the problem.
