This non-technical, non-mathematical introduction to some of the most bizarre ideas from the work of Albert Einstein is designed for people with little or no science background. We use analogies, thought experiments, examples drawn from everyday life, and a bit of humor to describe Einstein’s revolutionary concepts, how scientists have confirmed them, and what they mean to the average person. You will come away from this course with a new appreciation of the physical world and its behavior under extreme conditions. You’ll also see why Einstein’s ideas continue to fascinate both scientists and science fiction fans.
Students will be provided with an overview of Einstein’s ideas, and the way that science (especially astronomy) has confirmed the predictions of his theory. In the process, the students will become acquainted with such notions as the breakdown of simultaneity, E=mc2, anti-matter, black holes, gravitational lenses, gravitational waves (just recently confirmed), and time dilation. We’ll also look at the effect of Einstein’s ideas on science fiction stories and films, as well as on music and other branches of the humanities.

Andrew Fraknoi is the Chair of the Astronomy Department at Foothill College (retiring in June 2017), and a Senior Educator at the Astronomical Society of the Pacific. He served as the Society’s Executive Director (1978-1992) and created several NSF-funded national astronomy education programs for them. He is lead author of “Astronomy,” a free on-line introductory college-level textbook, published by OpenStax. He has been teaching a non-technical course on “Einstein and Modern Physics” for more than 30 years at both Foothill and the University of California Extension.
This course will be lecture with visuals and some discussion. Handouts and suggested readings will be provided.
