Historians and anthropologists have a distinct advantage over geophysicists when it comes to studying history. Historians have yellowed letters and books to read. Anthropologists have cave paintings and hieroglyphics. But geophysicists must read the Earth itself, which isn't always easy. Sometimes reading the Earth's “history book” takes a seven‐story ship with 12 floating laboratories and a gigantic drill to extract cores of sediment from the seafloor.
