Science is too important not to be a part of popular culture.

For the first time, we saw our world, not as a solid, immovable, kind of indestructible place, but as a very small, fragile-looking world just hanging against the blackness of space.

(On the energy radiated by the Sun) It's four hundred million million million million watts. That is a million times the power consumption of the United States every year, radiated in one second, and we worked that out by using some water, a thermometer, a tin, and an umbrella. And that's why I love physics.

There is so much left of it to explore.

Don't undermine the science just because you don't like the economics. That's a dangerous slope, because the problem of course is you're not undermining just that, you're undermining the basis of rational decision-making in society.

If people don’t have an understanding of what science is and what scientists do, then they can tend to think that global warming, for example, is just a matter of opinion.

In a sense I feel very much a part of the cinema now in a way where when I come back to the theater now I feel like a visitor. The cinema is really what I enjoy. I want to do more independent movies.
