Always entertaining, Dr. Rosenberg once again infused organic chemistry, political history, and his characteristic dry wit into a captivating lecture. Without going into each experiment in detail, I was most interested in the trend of coincidence. Some of these scientists began their world-famous experiments with ignorant, and sometimes completely unfounded hypotheses. But thanks to the curious workings of Lady Luck, they stumbled upon some of the most influential pieces of knowledge in history. Very neat to think about!
