Coffee+Discussions

Our tentative plan is to have coffees **every weekday at 10:00 a.m. in the "Founders Lounge," (Rm. 1201)** during which we will discuss topics of current interest, astro-phs, various papers, etc. Each day, one of us will volunteer or be asked to lead the discussion and choose the general topic. However, the flow of conversation should never be restricted to a narrow focus.

If you would like to use the wiki to record/extend a discussion from morning coffee, please include a link to a discussion page under Comments. (See Further Discussions for more information about discussion pages.)
