The last time I went to a lecture at Butler University, it was to see Michael Pollan, the author of "The Omnivore's Dilemma" and "In Defense of Food." We were pretty early, but we still got sent to the hastily (and very nicely) assembled overflow room ... which also overflowed.
Can an astronomy lecture attract the same crowd? We'll see. Robert Kirshner visits this coming Monday for a lecture titled, "The Extravagant Universe: Exploding Stars, Dark Energy and the Accelerating Cosmos" (also the title of his book). Kirshner teaches at Harvard, where his research focuses on dark energy and the accelerating expansion of the universe.
The event is at 7:30 p.m. Monday in the Atherton Union Reilly Room (and maybe some other rooms, too).
