If you look at the purported dangers of salt or fat, there is no consensus of support in scientific literature. So I would ask first: 'Is it possible to have an informed government that actually follows the science?' From what I've seen, it's not likely.

I do love science fiction, but it's not really a genre unto itself it always seems to merge with another genre. With the few movies I've done, I've ended up playing with genre in some way or another, so any genre that's made to mix with others is like candy to me. It allows you to use big, mythic situations to talk about ordinary things.

A third ideal that has made its way in the modern world is reliance on reason, especially reason disciplined and enriched by modern science. An eternal basis of human intercommunication is reason.

It is characteristic of science that the full explanations are often seized in their essence by the percipient scientist long in advance of any possible proof.

The recognition of the art that informs all pure science need not mean the abandonment for it of all present art, rather it will mean the completion of the transformation of art that has already begun.

The relevance of Marxism to science is that it removes it from its imagined position of complete detachment and shows it as a part, but a critically important part, of economy and social development.

We must always emphasize research and development of science and mathematics, and I can think of no better way to achieve this than through our future in space.

Science fiction is no more written for scientists that ghost stories are written for ghosts.

I sort of was good at writing essays. I was never very good at mathematics, and I was never very good at algebra. I loved science, but I wasn't sure of it.

Whenever you deal with science fiction you are setting up a world of rules. I think you work hard to establish the rules. And you also have to work even harder to maintain those rules, and within that find excitement and unpredictability and all that stuff.
