In way of explanation the authors give us this. “The field is mired with images of weird old men electrocuting themselves, strange equations, esoteric concepts, indecipherable books, etc. To most, physics is simply unapproachable. We say ‘NO WAY’ give it a chance!”

So I did. I found out that if at a concert I walked around, the music would sound differently as I walked. Just as a train with its horn blowing sounds differently as it approaches me than passes me. Those in the know have heard the Doppler effect.

Are you used to thinking of an atom as electrons whirling around a nucleus? Quantum theory will dispel that nice and simple image, replacing it with a conceptual map showing where electrons most likely would found as they spun around the nucleus. A graphic analogy illustrates the concept. Are you having fun yet?

You can discover the physics behind the question, “Why are Astronauts able to float around?”. Why doesn’t gravity pull them down? The site forces you to give it your best guess, then tells you whether you are right or wrong and gives you a concise explanation.

Take a look at how roller coasters work and how safe you might be if you designed your own. The sun earth and moon are also brought into focus to explain about eclipses. Einstein’s theory of relativity is superbly presented by illustrating what might happen to your house if it was traveling at the speed of light.

Most of the explanations use interactive experiments that let you “explore physics in action by dropping virtual tennis balls off the Empire State building or the Golden Gate Bridge, practicing your dunk shot, and riding a roller coaster.” If you have made it a virtue to distance yourself from understanding physics, this site gives you a second chance.
