Lynn Margulis was a revolutionary scientist, who died late last year. Her theories about the way life evolved and the interlinked systems of cooperating organisms that constitute the biosphere of our planet inspired many — even while sowing controversy in the conservative realms of her own field of study. As her son Dorion Sagan puts it, Margulis had “a congenital lack of fear,” and she pursued the truth of the world around her regardless of the outsider status the pursuit gave her in some communities.This BBC Radio 4 episode of The Last Word feature talks about Margulis’s fascinating contributions to scientific understanding, and feisty personality. The section on her starts around 13:30. Later this spring, the University of Massachussetts is holding a symposium on the legacy of Lynn Margulis. Details below: Lynn Margulis Symposium—A Life in Science: in Memory and Celebration Friday March 23 to Sunday March 25, 2012 The University of Massachusetts, in collaboration with the family and friends of Lynn Margulis (1938-2011), cordially invites you to a Symposium, March 23-25, 2012, celebrating her life and work. Although the Symposium is still in its early planning stages, we wanted to alert you and other interested parties you may know in order to provide the lead-time needed to save these dates and arrange for travel to and from Amherst, Massachusetts. We are very excited about this opportunity to gather in memory of Professor Margulis, and to explore the history, importance, and future of her intellectual accomplishments. As plans take shape, they will be posted to: www.geo.umass.edu/margulis_symposium.html Preliminary Schedule of Events Friday March 23, 2012 Welcome and Lynn Margulis Film Festival Saturday March 24, 2012 Welcome followed by seminars on Gaia, astrobiology, symbiosis, and a tribute dinner with Peter Westbroek, William Irwin Thompson, and a new essay by James Lovelock Sunday March 25, 2012 Community and colleague comments and an afternoon field trip in memory and celebration to Lynn’s favorite swimming hole (and last research site), Puffers Pond Lynn Margulis, along with her son, Dorion Sagan, coauthored and curated our Sciencewriters Series.
