upon review of the original articles on the subject written some time ago and having a little time to reflect on the subject at hand, i thought i would add that it was strange that Einstein's name and contribution to the subject had NOTbeen mentioned at all !!! NAMELY his nobel winning Photo Electric Effect! E=hf was Einstein's IDEA! HAS ===> EVERYONE <=== FORGOTTEN AL EINSTEIN ?!?!? peace and love, and, love and peace, (kirk) kirk gregory czuhai p.s. i do not think he is related to me, but i think he tried to work pretty hard at physics at least for a while from what some one told me once or twice, right?
