Simply put, this is cool physics and other sweet science. Here are some of the questions tackled in this series of short videos.

Have you ever wondered why you look up and see a dark sky at night? What is a sport? Do arbitrary and technophobic rules matter? What if there were a tunnel through the middle of the earth and you jumped in? Who’s faster over 10 meters – the fastest sprinter in the world, or gravity?

London Bridge has already been rebuilt twice! But what happened to the bridges that came down? Which is the most intense Olympic throwing event? Shot put? Hammer? Discus? Javelin?

What is mass and what does it have to do with the Higgs Boson? How do you know when you’ve “discovered” a particle? What do we mean by “discovery”?

Where does all the stuff in the universe come from? If gravity is so attractive, why doesn’t the earth just crash into the sun? Or the moon into the earth? Just because there are four dimensions doesn’t mean there’s a “fourth dimension”.
