"Meteorites are delivered to us free of charge," says Ralph Harvey, a professor in the department of Earth, environmental, and planetary science at Case Western Reserve University.

For me, it was a welcome label for the type of curiosity that had driven me to major variously in physics, archaeology, and English in college. I wanted to turn things like the universe, human society, or language inside out and find out where they started and how they evolved. I ultimately wended my way through college as a physicist with an English habit, but, despite the rationalizations I presented to relatives around the Thanksgiving table, I really had no clear idea how, or even if, I’d ever blend these interests later in life.
