The magnet induced a current in the copper pipe, which in turn produced a magnetic field. The direction of this current then opposed the change in the magnet’s field, resulting in the magnet being repelled and thus falling more slowly. Neat.

HAHA… ok Hemant Mehta (of FriendlyAtheist.com) toooootally got me in this +The Atheist Voice video. I didn't click play and was looking in the doobley doo on the YouTube video for what he was going to talk about.
This is awesome… Neil deGrasse Tyson is such a great front man for the world of science and listening to him as he explains why Stephen Hawking is the ultimate badass of the science world is crazy fun.
