Today in Science —> Alfred Wegener

1912 – German geophysicist Alfred Wegener first presents his theory of continental drift.

Wegener’s theory was poo-pooed for a long time, but was finally accepted by 1960, 30 years after Wegener’s death. Now, using satellites, we can measure how fast the continents move. We know, for example, that Europe and North America are moving apart at about the same rate your fingernails grow: about an inch a year.
