Speaker: Thor Olson
Topic: “The Modern Eddington Experiment”
In which the author describes his attempt to reproduce the measurement that made Einstein famous, using modern equipment.
Sir Arthur Eddington famously travelled to an island off the coast of Africa for the 1919 total solar eclipse, in order to photograph the positions of the background stars and compare them to their known positions. If Einstein was correct, they would appear to be slightly deflected by the sun’s gravitational field. This presentation will provide some historical background, and describe my attempt to replicate the measurement nearly a hundred years later.
Monthly meetings are open to all – you needn’t be an MAS member to attend. These meetings normally take place the first Thursday of each month at the Fairview Community Center in Roseville (“Great Room”). Monthly meetings start at 7:00 p.m. and last about two hours.
Each meeting features Board member introductions, general announcements, “Better Know a Constellation”, normally presented by a member, main speaker (around 45 minutes duration) and an after-meeting social gathering. Society business is occasionally transacted as needed.
