Yes, we all know the names of Einsteins various theories, but how much do you really know about what they mean and how they work? You may not have to know the ins and outs of the theory of general relativity to get through your day-to-day life, but it’s always there in the background shaping the spacetime around you. Might as well know how it works.

In a video for Fusion, Walter Isaacson—biographer not only for Albert Einstein but alsoBenjamin Franklin and more recently, Steve Jobs—does a quick run-through of the theory of general relativity in language anyone could understand and explains how it establishes that gravity and acceleration are basically the same thing. And it only takes three minutes! Give it a watch, you’ll be a better, smarter person for it.
