The argument has always been made, and it will always be made, that we know enough about the universe. You could have made it in the 1920s; you wouldn't have penicillin. You could have made it in the 1890s; you wouldn't have had the transistor. And it's made today, in these difficult economic times. Surely we know enough. We don't need to know anything else about the universe.
Let me leave the last words to someone who is rapidly becoming a hero of mine. Humphry Davy, who did his science at the turn of the 19th century. He was clearly under assault all of the time. We know enough at the time of the 19th century. Just exploit it. Just build things ...
