Happy birthday, Relativity!

What are you doing to celebrate the 100th anniversary of Albert Einstein's great discovery? Me, I've started reading Brian Greene, The Fabric of the Cosmos, to make sense of it all. Greene writes, "In June 1905, Einstein wrote a paper with the unassuming title 'On the Electrodynamics of Moving Bodies,' which once and for all spelled the end of the luminiferous aether." (p. 44) I kind of miss it, that comforting glow of something that was never there. But that's all right; Greene is terrific at explaining the biggest questions in the universe, in fact, the universe itself, space and time, and does it in terms even I can follow.
