Paradigm Shifts

Hey, guys, I'm writing a college paper on paradigm shifts. I'm focusing on paradigm shifts in society, namely things that changed the human flow. my current examples are jesus' teachings, the copernicus' heliocentric theory, and the Magna Carta. Know any goo d sites, better examples, or just want to talk about it?

para- that part reminds me of falling from planes.

digm- that means you gotta like them.
