E=mc^2 is Incomplete

In this video, Minute Physics does a really nice job of explaining the missing part of the most famous equation in the world, E = mc2.  It seems that that simple version of the equation only holds true for objects that are not moving.  These moving objects have momentum which is represented as p in the slightly more complex equationE²=(mc²)²+(pc)².  If you pay attention, you'll even see why it is that, according to Einstein, nothing with mass can move at the speed of light (or faster).  
Watch and enjoy.
