Library Presentation by Phil Deutchman: An Exploration of Black Holes

This presentation, aimed at a general audience, will look at the hypotheses offered by the famous theoretical physicist, Stephen W. Hawking concerning radiation that might come from Black Holes.  If this radiation occurs, it would mean that Black Holes are not so black after all.  The talk will be a qualitative discussion (mathematics kept to a minimum) about Professor Hawking’s main ideas that come from General Relativity and Quantum Physics. Using these ideas, he creates the notion that Black Holes might radiate energy away like a hot object and evaporate! This hypothetical phenomenon is called: “Hawking Radiation.”  It is also fascinating to see how Newton’s Classical Physics, Einstein’s General Relativity, and Quantum Physics each treat the idea of “vacuum” differently.  The program will be presented by Phil Deutchman, Emeritus Professor of Physics, University of Idaho. Phil taught physics at the undergraduate and graduate levels and conducted research in Nuclear and Particle Theory at the University of Idaho for 34 years.  He retired in 2002.  His interests are in understanding the fundamental ideas, interpretations and phenomena described by Quantum Physics and Relativity.  The program takes place at the Sandpoint Library on Thursday, July 30, 2009 at 7:00 pm.
