Following the excursion in the Peace Park and Atomic Bomb Museum, the PAHSA students attended a lecture by Prof. Hiromichi Umebayashi on the Denuclearization of East Asia. This technical lecture covered the physics of nuclear weapons, and the history of many international political issues surrounding the development and attempted reduction of nuclear weapons. Prof. Howe also offered fresh insight into several ways that nuclear disarmament can be achieved, namely in reference to the current North Korean effort to gain long-range nuclear warhead deliver capability.
The day was concluded with a roundtable discussion between Prof. Matsuyama, Prof. Howe, Dr. Patcharanarumol and the PAHSA students. During this session, many of the students offered very personal experiences that were relevant to today's topics. This exchange proved to be very stimulating and helped to solidify new concepts and perspectives for all individuals.
