This course will introduce the student to circumstances involving events that significantly influenced history. Ancient and modern history are filled with stories that are puzzling or awe-inspiring, or both. One conjecture is that history, recorded or inferred, is often driven by random events that are not fully understood or appreciated until ‘later’. For example, we will address the Tunguska, Russia atmospheric explosion in June 1908 and the Great Molasses Flood of January 1919 in Boston, among others. Instructor Bill Koenigsberg had a 4-decade-long career in industrial research involving a broad range of disciplines. He has always been interested in finding the root cause of problems (technical or otherwise). Class will be held on Tuesdays, October 23 – November 27 from 10:00-11:30 AM.
