In our second episode devoted to the life and work of Edmond Halley, we recount his three voyages aboard the Paramour to create a map of magnetic variation and survey the tides and currents of the English Channel.  We also cover his predictions on the return of the comet of 1682, now known as Halley's Comet, his discovery of the proper motion of the stars, his translation of the works of Apollonius, and his work as Britain's Astronomer Royale among a host of other accomplishments.
