As for your physics, as we say in german, "Die gedanken sind frei." Ben --------------------------------------------------------------------------- RULES OF REASONING IN PHILOSOPHY. RULE I. We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances. To this purpose the philosophers say that Nature does nothing in vain, and more is in vain when less will serve; for Nature is pleased with simplicity, and affects not the pomp of superfluous causes. -- Sir Isaac Newton - Principia Mathematica. Nature doesn't care what you say in German and she's not too bothered about tact or diplomacy either. If you want to understand her you'll need a working brain, she can fool you very easily. As for your thinking, as we say in Anglo-American, it sucks. This pencil is broken, I can see it is and even the URL says so. http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/optpic/brokpen.jpg Want to fry your gedanken with that?
