On most Saturday mornings during the main school year, the University of Michigan Physics Department hosts Saturday Morning Physics. The lectures are designed for general audiences and are an opportunity to hear physicists discuss their work in easy-to-understand, non-technical terms, though sometimes I think they’re still pretty technical. The multimedia presentations include hands-on demonstrations of the principles discussed, along with slides, video, and computer simulations. Sometimes they have really cool experiments.
My favorite topics so far have been the physics of photography, which was a multi-lecture topic, and most recently one on solar powering your house. It also depends on the speaker, some a quite entertaining even if I don’t understand half of what they’re talking about! If you’re interested in checking out a lecture before committing on attending, they record all of them and are archived on their site.
They’re held Saturday mornings at 10:30-11:30 AM in 170 Dennison on the University of Michigan’s central campus. I advise getting there early to secure a good seat and to make sure you can partake in the free coffee, donuts, bagels, and juice! Parking is only $2.00 across the street at the Church Street parking garage.
