VIDEO(S) Of THE DAY: Understanding Physics? It Only Takes A Minute
April 16, 2012

What exactly is the difference between the third and fourth dimensions? Why do we measure the distance from here to other planets in light years? And what's the deal, anyway, with E=mc2?

For anyone with a background in physics, these may be relatively simple questions, but for those who might appreciate a quick, watchable recap of some basic scientific ideas, there are, helpfully, at least TWO online video series dedicated to elucidating physics concepts in one-minute clips.

MinutePhysics is a YouTube channel featuring animated clips by Henry Reich, a graduate of Canada's own Perimeter Institute for Theoretical Physics AND a film student at the University of Southern California. Here is his explanation for the use of time to measure distance (make sure to check his clips explaining the fourth dimension and the theory of relativity, too):

A similar series comes from New Scientist TV, which also features a collection of short, explanatory clips under the label One-Minute Physics - one of which is Henry Reich's MinutePhysics animation about Einstein. (Do physicists all get along?) Here is their latest, featuring a Lego pirate, a wave tank, and an explanation for how freak, monster waves can appear from seemingly nowhere to sink ships:
