I am new to this forum, and I hope that my presence will be accepted. My degrees are in Eng/Pol-sci so I am not trained in classical or theoretical physics, just general science. My point is that there are some of us that are unable to read formulas, or to prove points with high tech equipment. We can only rely upon what I call "Junkyard Physics". I am here to learn as well as teach. I feel as that I might be able to contribute by translating some of the more interesting topics into a "common" example for those of us that are "dumb" in physics, but not so "dumb" in other areas. I hope that the more learned members will tolerate us meddlers as we try to understand highly technical ideas out here in the "junkyard". Thank you.
