"I think when I was in college, my Physics professor was some guy named Sir Isaac Newton." Bwahahahahaha! I can definitely relate. I'm working on them now and I think we can break this stuff down to make it more understandable. I have about 5 years of combined physics schooling between high school and engineering school, and even I had trouble making sense of the manual. (No offense, Anthony). I figure I can break it down into parts, and if we work on one variable at a time it will be much easier. :) Paul
