The Metaphysical Club will meet on Thursday, June 26, 7:00 PM at the SpringPark Sports Club & Community Center, 3300 SpringPark Way, Garland. Frank Prokop will speak on the conflict between classical and quantum physics, as exemplified by Albert Einstein and Werner Heisenberg. Because of the philosophical implications of Heisenberg's "Uncertainty Principle", Einstein could not accept the changes to the classical notions of causality and the nature of matter required by the principle. The implications of each of these views will be explored. A discussion will follow.
