Contemporaries only know the authority figures and the loudmouths. And the people born into power. But it takes perspective to know who's carrying the load. Nobody here has a clue who Johannes Kepler is. All they know about Galileo is that he's a teacher who got in trouble with the Inquisition. I doubt anyone's heard of Francis Bacon. Even in Britain, nobody really knows him. He's just a guy with a funny name.

Lest we forget, the birth of modern physics and cosmology was achieved by Galileo, Kepler and Newton breaking free not from the close confining prison of faith (all three were believing Christians, of one sort or another) but from the enormous burden of the millennial authority of Aristotelian science. The scientific revolution of the sixteenth and seventeenth centuries was not a revival of Hellenistic science but its final defeat.

Thanks to the comic book publishers. Batman and Captain Marvel were responsible for my learning to read at least a year before I showed up at school. They got me interested in writing. Started my first novel at about eight. The title: 'The Canals of Mars.'

When I was teaching English and trying to get kids passionate about reading, the most effective weapon I had was 'The Martian Chronicles.'

I've tried to quit writing several times, but I enjoy it too much.
