Alyssa Goodman: Lost without Longitude , at Harvard Museum of Natural History, Cambridge, MA, Thursday, May 14, 2015

One of the most important scientific challenges in early eighteenth-century Europe was the search for a reliable way to determine longitude at sea. Using a free interactive program called “WorldWide Telescope,” Alyssa Goodman will demonstrate how various historic and modern systems for measuring longitude at sea work (or fail to work), highlighting key life-saving techniques to find one’s position using the motions of stars and moons, as well as magnetic anomalies. Go back in time and discover what it was like to find one’s way before the era of GPS devices and smartphones.
