The Boulder Cosmology Group meets at 6PM 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.

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

2019   Second and Fourth Wednesdays: Selected DVD lectures from Professor Steven Gimbel's course on “Redefining Reality: The Intellectual Implications of Modern Science”. Followed by the full 24 lecture course by Professor Benjamin Schumacher “Quantum Mechanics: The Physics of the Microscopic World”.

We will watch the 30 minute lectures using 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).
