Hello, I used to hang out here many years ago, like 30 years ago. I am have some definite ideas about physics that might or might not be important. I have seen and done some amazing things in terms of science in the US Navy. I am, and have been for some 30 years, the "Unofficial Chief of Naval Innovation." I am very interested in rail guns, and EM launchers, which I helped introduce into the fleet. But generally I am an empirical physicist. I have run thousands of experiments for the Navy and for my own company. I am most expert in manufacturing science, particularly metals casting, which involves a great deal of physics. I also specialize in optics. I invented an entire class of materials, which became a whole field new of science, and was one of the leaders of the materials science revolution.
