PS2B - Types of Interactions
Paul Andersen explains how objects interact when touching and at a distance. Electromagnetic forces are very important when objects are touching and fields explain both electromagnetic and gravitational forces. The strong and weak...

Maxwell's Equations: Crash Course Physics
In the early 1800s, Michael Faraday showed us how a changing magnetic field induces an electromotive force, or emf, resulting in an electric current. He also found that electric fields sometimes act like magnetic fields, and developed...

How Antarctica Froze Over
Antarctica wasn't always covered in kilometer thick ice sheets, in fact, scientists have spent years figuring out what turned this once lush continent into its current icy state.

TED: Your kids might live on Mars. Here's how they'll survive | Stephen Petranek
It sounds like science fiction, but journalist Stephen Petranek considers it fact: within 20 years, humans will live on Mars. In this provocative talk, Petranek makes the case that humans will become a spacefaring species and describes...

Magnetism: Crash Course Physics
You’re probably familiar with the basics of magnets already: They have a north pole and a south pole. Two of the same pole will repel each other, while opposites attract. Only certain materials, especially those that contain iron, can be...

Why So Many Countries Claim Antarctica But Can’t Do Anything With It
Antarctica is not like every other continent. Aside from its extreme cold and vast ice sheet, it's also the only major piece of land that has never had a human settlement rise up on it. And because of this, as it was explored in the...
