Hello everyone :) Been reading your forum for a couple of years as a visitor and decided to take this opportunity to thank everbody for there exceptional intellect and insights. I have been a science fan since a child, but lack the formal education to pursue such vocations. Most of my knowledge comes from pubic school, independent reading or the Science Channel. I hope in the event that I can contribute or ask a question, the powers that be will forgive my ignorance of science and show some tolerance. After reading here, I have learned a great deal about many subjects... Much of which is far superior to my own research. Thanks.
