Hi, I believe I am supposed to introduce myself. My name is LukeH and I am a retired blue collar worker with a general high school education. Some algebra and no higher math, no chemistry or physics, the only science I studied was biology for three years because it really interested me. During my life, I have read a great deal of science related articles because it is exciting to see what the pioneers are learning. I haven't focused on any one area but read with interest new things. New to me, at any rate. I was posting on the stack exchange and realized that it was targeted to more professional and near professional physicists and astronomers. This site was recommended to me and I hope to enjoy my stay.
