Some days I'm just struck by how much there is to know about the world, how much I'd like to learn, and how little time I really have to get things done. There are so many things that interest me, but there's no possible way I can dedicate time to all the topics.
Today I ran across this video podcast series called "Saturday Morning Physics" (link opens iTunes). It's a series of 45 to 60 minute long physics lectures from the University of Michigan designed for the general public. Based on the audience in the videos (retirees), it appears these lectures were probably really given on Saturday mornings for the general public. (Not many college students would get up early on a Saturday morning to listen to a physics lecture for fun.)
Anyhow, it's an amazing resource, currently with 38 videos available - and it's just one small piece of an enormous collection of education videos found on the Internet.
