Einstein's Proof of E=mc²
You see it everywhere — t-shirts, coffee mugs, posters ... but why was Einstein's most famous equation such a turning point in our understanding of the relationship between matter and energy? The short video demonstrates the math...

How to Break the Speed of Light
Have you ever wanted to break the speed of light from your backyard? Something seemingly impossible, and technically improbable, looks impressive thanks to the "magic" of science. The brief video explains how photons can travel from your...

When the Book is Better than the Movie
Sometimes the book is better than the movie; other times, the movie comes out on top. A video discusses the topic of novels and their film adaptations, pointing out specific texts and how the tale translated to the big screen. The...

Crash Course Physics #42: Special Relativity
So we've all heard of relativity, right? But, what is relativity? And how does it relate to light? And motion? In this video episode of Crash Course Physics, Shini talks to us about perspective, observation, and how relativity is REALLY...

Pbs Learning Media: Motion and Relativity
This video from the American Museum of Natural History illustrates how motion is described relative to a frame of reference, and how Einstein's special theory of relativity is needed to describe the motion of objects traveling near the...
