Sigma Xi Science Cafés

Sigma Xi partnered with WGBH to lead a revolution incafeLG communicating science in the U.S. This revolution takes place in cafés, bars, bookstores, libraries, museums and theaters. Science Cafés help the public connect with science. Scientists and engineers informally share their research during a conversational exchange in a friendly setting. Through working with key partners, encouraging members to participate and supporting its chapters, Sigma Xi continues to be at the forefront of promoting and supporting Science Cafés around the country. 

WGBH Partnership


WGBH, in association with Sigma Xi, launched a comprehensive Web site at This site was created with the help and input of many Science Café organizers, following the first national conference of Science Café organizers held at the Sigma Xi Center in 2006. At this Web site, Café organizers will find resources and ideas to help in all aspects of planning and promoting these events—from publicizing and supporting them, to choosing topics, speakers and venues. Free resources include an interactive map of Science Café sites around the country and short clips presented in the PBS television series NOVA scienceNOW, produced by WGBH.
