“Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?” JOSEPH LEONARD TUBERGEN Physics Major, University of NC Wilmington Erwin with his psi can do Calculations quite a few. But one thing has not been seen: Just what does psi really mean? -Erich Hückel This was the title of the famous (EPR) paper by Albert Einstein, Boris Podolsky, and Nathan Rosen in their analysis of the interpretation of quantum theory. One cannot interpret quantum mechanics without first adopting a philosophical position towards “physical reality.” The possibility of hidden variable theories will be discussed in relation to their implications concerning determinism and reality. We will cover the history and foundational aspects of quantum mechanics that eventually led to the derivation of Bell’s Inequality. This inequality provides a condition to test if quantum mechanics is compatible with local hidden variable theories and, hence, local reality itself. We will also discuss Alain Aspect’s experimental test of Bell’s Inequality. This talk will shed light on the nature of this ongoing debate. The "paradox" is only a conflict between reality and your feeling of what reality "ought to be." -Richard Feynman Friday, December 2, 2011 2:00 PM DeLoach Hall, Room 212
