The Boulder Cosmology Group meets 6PM to 8PM for DVD lectures on the Second and Fourth Wednesdays of the month and reading discussions on Third Mondays at the Main Library. All meetings are free and open to the public. (Monday discussions are usually in the second-floor Flatirons Room and Wednesday lectures in the first-floor Boulder Creek Room). Dates and locations are subject to change. Changes from the normal pattern are noted below.
Note: While the library closes early because of the pandemic, keep up with the Wednesday Lectures on your own at home, and conference with Zoom for the Monday book discussions.
We missed quite a few lectures in 2020. If you didn't keep up then you could still watch them on Kanopy. The links are in the 2020 Schedule. Remember you can Kanopy stream Great Courses lectures without affecting your monthly Boulder Public Library Kanopy quota.

See http://www.sackett.net/cosmologyAll.htm for a list of all meetings of the Cosmology Group since it began in 2003.

2022   Second and Fourth Wednesdays: DVD Lectures will resume when we are able to meet in the library's Boulder Creek Room.
When we can meet in the library we use an “interruptus” format: at any point during the lecture anyone in the group can say stop and ask a question and the rest of the group will attempt to answer the question before proceeding. We will attempt to cover two lectures in each meeting. If we don't have time the next DVD lecture meeting will start with the second lecture (and this schedule will be adjusted).
