I've been having serious difficulty completing all sorts of physics problems lately, and I felt that maybe I wasn't understanding the basic principles of SHM and gravitational forces etc. So naturally I turned to good 'ol Walter. But I found that instead of listening to his lectures, I was often just waiting to watch him draw a dotted line on the blackboard. So I had to re-watch a number of lectures and I was wasting a bit of time. So I turned to the other great lecture-er who some of you may not be aware of "Richard Feynman." His lectures on our current material are a bit harder to find hosted anywhere for free, so I currently own a set of Feynman lectures on CD. Its been a tremendous help to me, and although it was a bit expensive I think everyone ought to know about Feynman.
P.S. Does anyone know how many blog-posts we should have up by this time? I know I'm behind at least one.
