Ok, that mathematics thing is something I read a while back. Let me ask you something though, since I know nothing about the state of modern mathematics. When I think of genius I don't just picture someone who solved a tough proof or made some kind of advancement that happens every few years. I mean someone who revolutionized some area of mathematics or science. Einstein, Newton, Descartes, Copernicus (helio-centric theory is believed to have been born in his 20s), Tesla, probably the guy who invented the wheel. All these guys had their big eureka moment in their 20s. Then many of them went on to postulate all kinds of wrong theories as they got older.

Are there any examples of people having the genesis of some idea that revolutionized their field while in their late 30s or beyond?
