Relativity

For anyone who's interested, I'd like to bring up one of my favorite concepts: relativity. Relativity means relation to - it's a comparison term. For example, if you drive a car at 90 miles per hour, then are you driving fast? Relative to the common civilian driver, you are. But relative to a Nascar driver - well, you get the picture. It's a beautiful thing, relativity. Did you know that you can fall at very high speeds without feeling any pain? Just look at your motion relative to the next astronauts who launch off in a rocket. Relative to the physicist shooting into space at very high speeds, you, and the entire earth and surrounding universe, are all falling at very high speeds. To the astronaut, the rocket isn't even moving. Intriguing, is it not? I hope I have incited within you a deep passion for physics. If not, you can always write a blog.

It's nice to know that we can find scientific, philosophical irony in unexpected places. Thank you Albert Einstein.
