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.

Alyssa Goodman: Big Data vs. Wide Data, at NOAO, Tuscon, AZ, Monday, March 9, 2015

In life, more of the same isn't always better. Often, variety is more important. In Science, using more kinds of data, rather than just more data, often helps answer the hardest questions. In this talk, I will discuss tools for visualizing several data sets at once. In some cases, the visualizations are straightforward (such as overlaying layers imagery or catalog data on images, in tools like WorldWide Telescope or Aladin), but in other cases, more subtle "linked-view" visualization amongst data sets and visualization types yields the deepest insight (e.g.
