Newton's rÃ©sumÃ© is certainly more diverse; he's got the gravity thing, calculus, his contributions to optics, and his laws of motion. Each of those things would make him a standout genius in history. Beethoven, though, has scores of brilliant compositions and the impressive feat that he overcame deafness to write them. Beethoven was the central figure in music's transition from Classicism to Romanticism, while Newton was able to formulate calculus while he was stuck at home for two years during a plague outbreak. Neither of these guys is a slouch, but who gets the genius nod?
