Our first class meeting will be on Tuesday, September 4 at 11:20 am, in the seminar room in the Physics and Astronomy Department, in the Science Center (room 113). Expect to get a reading assignment (that may include a short worked problem or two) about a week before the first class meeting.

Look over these images and movies of last summer's solar eclipse and think about this: When we say the Moon and Sun appear to be the same size, what is it, exactly, that's the same about their sizes? Certainly not their diameters or radii in meters.

Upcoming Events

What's up in the sky this week - the sky is always changing: keep an eye on the bright objects that are up in the sky each night.

The department has regular talks – colloquia – given by visiting scientists. Check the department colloquium schedule to see the list of talks. You'll find titles and descriptions of the talks, which are generally on Fridays at lunchtime. We will have four or five this semester, with at least one on astrophysics.


Class Information

Prof. Cohen's office hours will generally be: Tuesday and Thursday from 1:30 to 3:00 and Wednesday from 3:00 to 4:30; weekly deviations from this schedule will be posted here.
