In the fall of 2017, a new working group on the history and philosophy of mathematics and logic was started in the Orange Country-Inland Empire area of Southern California. The group constitutes a collaboration of four schools: Chapman University, Pitzer College, CS San Bernardino, and UC Riverside. Roughly once a month, it provides the forum for a talk by an outside speaker, usually at one of the universities involved. If you are interested in participating and want to find out more about the meetings, please send an e-mail here.
