What were we doing here? Traveling hundreds or thousands of light-years, to break our hearts?

In terms of stories I would buy for a science fiction magazine, if they take place in the future, that might do it.

I did that for 40 years or more. I never had any writer's block. I got up in the morning, sat down at the typewriter - now, computer - lit up a cigarette.

People as me how I do research for my science fiction. The answer is, I never do any research.

My old English buddy, John Rackham, wrote and told me what made science fiction different from all other kinds of literature - science fiction is written according to the science fiction method.

I'm doing a book, 'Chasing Science,' about the pleasures of science as a spectator sport.

For someone to be taken seriously it was valuable to have the appearance of someone who deserved to be taken seriously.
