"This is physics. It's also politics. The two are sometimes painfully difficult to keep apart." "Copenhagen", the 2000 Tony Award winner for Best Play, explores an explosive confrontation between science and politics. Inspired by actual events that have intrigued and baffled historians for more than 50 years, "Copenhagen" revolves around a 1941 meeting between two brilliant physicists, Niels Bohr of Denmark and Germany's Werner Heisenberg. The two men were long-time friends whose work together opened the way to the atomic bomb, but who were now on opposite sides of World War II. This pivotal meeting was a defining moment of the nuclear age, yet its true nature remains a mystery. Why did Heisenberg go to Copenhagen? What was he hoping to accomplish? The search for an unknowable truth forms the core of "Copenhagen." In the uncertain times of 1941, "Copenhagen" is a refreshing reminder of the value of seeking the truth.
