100 years of special relativity

Einstein developed his theory of special relativity a century ago. I recently read a whole series of articles on this in Discover magazine. The faster you go, the slower time passes for you, such that the speed of light always, to you, appears to be 299,792 km/s. If you go 9/10 the speed of light, you will be so lethargic that time will fly by on Earth while you hardly age at all... just so that time continues to appear to travel at that constant speed.

It reminds me of that DeNiro movie, Awakenings, but I've already written about that. :-)
