Another topic for idle blogging — the top 25 innovations in history, ranked in order of importance. In this list, spoken language is #1 (sort of) with relativity and quantum mechanics at #25. Religion is at #12, eight places ahead of the concept of science and 11 places ahead of evolution and natural selection (sorry, Derb). I probably would have put specialization of labor higher up than #17 and would have put eloctromagnetism (#24) ahead of water power (#21) and steam power (#22), since it’s supposed to be about the number of people impacted. Discuss.
