I don't deserve the most intuitive award -- but if you happen to have a "dumb luck" award category, I could qualify.

On another subject, I'm curious about your name, Petra. My grandfather was named Petros (Peter in English). He was born to Greek parents and emigrated to the U.S. from Smyrna, Turkey. Anyway, the name Petros, as I'm sure you know, means "rock." How apropos that you, Petra, are so interested in geology / seismology!

I've never heard the name Petra before, but I think it's a lovely name. Question: Is it pronounced with a short "e" or a long "e?"
