One of the advantages of living in a college town is that the guys I play ball with aren't exactly "dumb jocks." I've been in all kinds of very interesting discussions lately regarding science, theology, the existence of God, morality, and most recently- physics.
I was chatting with one guy who is a tenured physicist at ISU. He suggested a series of lectures by one of the most brilliant, and yet accessible, physicists of the 20th century- Richard Feynman (click here for the wiki bio).
We can all thank Bill Gates for purchasing these lectures and making them available to the general public (click here for the lecture series).
It's fun to re-learn physics when there is no grade or required credit on the line. Moreover, studying physics expands the mind and soul, and is not unlike studying Theology Proper.
