Scientists and science enthusiasts are still mourning the passing of Stephen Hawking, one of the great minds and spirits of our time.  In this introductory talk, Fraknoi will briefly summarize Hawking’s life, and talk about the importance of his scientific work.  He’ll focus particularly on Hawking’s work merging the world of the big and heavy (described by Einstein’s General Theory of Relativity) with the world of the small and light (described by quantum mechanics). Then he’ll describe how this merger led to the idea of mini black holes, “Hawking Radiation,” and the bizarre notion that black holes don’t have to be fully black.   No background in science or math will be required, but be prepared to have your mind boggled. 

Andrew Fraknoi

Andrew Fraknoi retired as the Chair of the Astronomy Department at Foothill College in 2017. He currently teaches non-credit astronomy classes through the University of San Francisco Fromm Institute and San Francisco State’s OLLI program. For 14 years, he served as Executive Director of the Astronomical Society of the Pacific.  Fraknoi was named Professor of the Year for the state of California in 2007 and often appears on the radio explaining astronomy in everyday language.  He is the lead author of a free, open-source, introductory astronomy textbook, published by the non-profit OpenStax project, and has also written two children’s books on astronomy. Asteroid 4859 has been named Asteroid Fraknoi to honor his contributions to the public understanding of science.
