Light always travels at a speed of 299,792,458 meters per second. But if you're in motion too, you're going to perceive it as traveling even faster -- which isn't possible!

Artist and writer Matt Collings takes the plunge into an alien world of equations. He asks top scientists to help him understand five of the most famous equations in science, talks to Stephen Hawking about his equation for black holes and comes face to face with a particle of anti-matter. Along the way he discovers why Newton was right about those falling apples and how to make sense of E=mc2. As he gets to grips with these equations he wonders whether the concept of artistic beauty has any relevance to the world of physics.
