Halley’s Comet has become so well known that it overshadows the English astronomer’s other work — but Edmond Halley (1656-1742) made important contributions to many branches of science. He worked out the size and shape of the Earth, as well as the size of the solar system; he mapped the Earth’s magnetic field, and studied the tides and monsoons; he tried to solve the problem of measuring longitude at sea; he predicted eclipses. And he was no couch potato: Halley sailed to St. Helena, a remote island in the South Atlantic, to chart the southern stars. On a recent visit to England, Dan Falk walked in Halley’s footsteps in an effort to learn more about his life and legacy.
