The Discovery of Longitude with Dr. Douglas Drumheller
Thursday, April 4, 2013
Afternoon lecture and Planetarium show: 1:30-3 p.m.
Evening lecture and Planetarium show: 7:30-9 p.m.
Early voyages of discovery were literally lost at sea on ships that could not determine their longitude. Indeed Christopher Columbus thought he was in the Pacific when he was actually in the Atlantic. Join Douglas Drumheller, Ph.D. for a special presentation about how John Harrison, an 18th-century clockmaker, changed all that. Drumheller will also describe his replica of Harrison's time machine and his plan to navigate the Atlantic with it. Following the lecture Jeff Dunn, supervisor of the Treworgy Planetarium, will present a planetarium show to further illustrate the underlying connection between time and celestial navigation.
