Physics, some of us get it, some of us don't. Either way, it's something that won't hurt learning (and it will impress that special someone in your life). So, why not be able to explain to them how Galileo, Newton and Einstein all fit into our understanding of the world around us?
This animated video from Asa Lucander can help you do that. It's a slick and stylish take on the history of physics, and it's only four minutes long.
Watch it, you'll be a better man for it.
