Greetings everyone. I'm new here as you can see. I'm a retired physicist and enjoy discussing physics. Keeps the wheels in the noggin spinning. I look forward to many interesting conversations. I usually spend most of my time in forums helping people learn math and physics. I hope to be useful here. Let's see what happens, shall we? :) My handle "Popper" comes from my favorite pholosopher if science, Carl Popper. I actually know someone who knew him personally. I just got his book The Logic of Scientific Discovery. Have any of you ever heard of it or better yet read it? I also just obtained the book The Structure of Scientific Revolutions by Thomas Kuhn, my second favorite pholosopher if science. Are you familiar with him and/or his work too? I'd love to hear your thoughts on it. As Fritz Rohrlich said If you're not doing philosophy then you're not doing physics.[/i] I believe that wholeheartedly. How about you?
