In recognition of our country’s 250th Anniversary, some members of the GLAS Education team recently made a visit to the historic Judy and Stanley Frankel Detroit Observatory (known as the Detroit Observatory) located on the campus of The University of Michigan in Ann Arbor. Kate Meredith, President/CEO of GLAS Education; Olivia Smithmier, Education Contractor; James Cudworth, GLAS Board Chair; and, intern Jamar Zhou, a computer science and physics major at University of Chicago, visited the Detroit Observatory to learn how 19th Century astronomers used mechanical instruments to precisely measure stellar locations and distances.
Built in 1854, the Detroit Observatory is the University of Michigan’s second-oldest building, now managed by the Bentley Historical Library with programs and efforts to make centuries of science relevant for a new generation. The Observatory currently houses many of the instruments 19th Century astronomers used to measure stellar motions and distances.
Smithmier is guiding an intern project this summer to demonstrate the operating principles of the sextant. The sextant is a tool that measures the angle between a celestial body and the horizon at a precise time of the day. Sailors once used it to determine their location at sea, and requires precise settings with STEM knowledge of astronomy, geometry and math to work properly. Smithmier designed the project to tie into America's 250th Anniversary to teach students how our forebears used the stars to find their way.
Studying with Smithmier this summer, Zhou is now working on creating 3D models that visually and tactilely demonstrate the principles behind the operation of a sextant. GLAS has some significant connections to the Detroit Observatory. Dr. Katya Gozman is a former GLAS intern, a current GLAS board member, and was a staff member at the Observatory while earning her PhD at University of Michigan.
