I am teaching a new Zoom course on the mysterious world of the atom, with lots of visuals and no math. It’s a six-week class for retired people:

Join me for a richly illustrated tour of the atomic world that lies beneath our everyday conception of reality. Using historical anecdotes, analogies from everyday life, thought experiments, and touches of humor, we’ll explore atomic theory from the Greeks to today, and look especially at the revolution in our understanding of the world of the very small that was begun by Einstein and others at the start of the 20th century — quantum mechanics, and its bizarre, yet experimentally verified, ideas of how things work inside the atom.

The class is through the Osher Lifelong Learning Institute through San Francisco State University. But anyone, anywhere can take it.  The time is Tuesdays from 12:30 to 2:30 pm (Pacific) via Zoom (Oct. 7 – Nov. 11, 2025)

Three easy steps to register:

1. Sign in or create a free account at: https://www.campusce.net/sfsu/account/signin.aspx
2. Join the Institute at: https://www.campusce.net/sfsu/course/course.aspx?catId=14(a modest fee)
3. Register for the class at: https://www.campusce.net/sfsu/course/course.aspx?C=559…

Please pass this on to a curious retired person in your life, if you are still working 9-5.

Happy fall to everyone in our journey around the Sun.
