Oscillations and analogies. Thomas Young, MD, FRS, genius

Thomas Young is arguably one of the greatest geniuses who ever lived, but most people have never heard of him, though he was renowned in his own era. He did important work in a large variety of scientific disciplines, but that was his downfall. Given the specialization of the present era, physicists do not appreciate how important his work in linguistics was, linguists do not appreciate the importance of his work in psychology, and so on. Despite his obscurity today, Young nicely exemplifies the traits that one finds in a genius of the first order: tendency toward analogical thinking, high intelligence, an amazing capacity for hard work, extremely wide interests, distaste for traditional dogmas, and very high self-esteem.
