The Martians are always coming.

I used to dig in the garden, and there isn't anything fantastic or ultradimensional about crab grass... unless you are a SF writer, in which case, pretty soon you're viewing crabgrass with suspicion.

It takes a certain amount of courage to tackle very hard problems in science, I now realise. You don't know what the timescale of your work will be: decades or only a few years.

I'd never thought about acting as a job. I was an engineer; I was in science and technology. I loved movies and television growing up, but I'd never thought about it as, 'Oh, that guy Denzel Washington is employed as an actor.'

Science has a culture that is inherently cautious and that is normally not a bad thing.

Star Trek' is a 'Wagon Train' concept - built around characters who travel to worlds 'similar' to our own, and meet the action-adventure-drama which become our stories. Their transportation is the cruiser 'S.S. Yorktown,' performing a well-defined and long-range Exploration-Science-Security mission which helps create our format.
