Intro to Quantum Mechanics http://www-theory.chem.washington.edu/~trstedl/quantum/quantum.htm l Today's single web page from physical chemist Todd Stedl provides a summary of the mysterious realm of quantum mechanics for the lay person. Having heard such terms as the "uncertainty principle", bandied about on popular television programs, but who are still in the dark about their meaning, will discover illuminating material on this branch of science. "This page is intended to give an ordinary person a brief overview of the importance and wonder of quantum mechanics. Unfortunately, most people believe you need the mind of Einstein in order to understand QM so they give up on it entirely. (Interesting side note: Einstein didn't believe QM was a correct theory!) Even some chemists fall into that category -- to represent physical chemistry our departmental [University of Washington, Seattle .ed] T-shirts have a picture of the ... atom, which is almost a century out of date. ...[T]ake a dip in an ocean of information that I find completely invigorating!" - from the website The page, using plain language, covers the basic topic of what is quantum mechanics, why it was developed, its importance and the problems with classical physics. Additional material is provided on its fundamental concepts -- discreteness of energy, the wave-particle duality of light and matter, quantum tunneling, spin of a particle and the ever-popular Heisenberg uncertainty principle. A selection of helpful graphics serve to clarify some of the concepts. ~*~*~*~*~ Was this forwarded to you? Want to subscribe? Send an email to 1stpicksites-request@xxxxxxxxxxxxx?Subject=subscribe.
