As I mentioned in the last episode (#21), I've got a whole list of topics I'd like to discuss that require at least a cursory background in modern (non-Newtonian) physics. So this week's episode is the first in a scattered series of 3 episodes that I'm in aggregate titling "20 Minute Lessons in 20th Century Physics." Tune in this week, and I'll give you a brief introduction to special relativity (listen closely, and you'll see just how special it is...). This episode makes lots of references to the scientific method, so make sure you've listened to episode 4 (October, 2005) if you're new to the podcast.
