The correct statement of individual rights is that everyone has the right to an opinion, but crucially, that opinion can be roundly ignored and even made fun of, particularly if it is demonstrably nonsense!

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.

What scientists are attached to is journeys into the unknown and discovering things that are completely unexpected and baffling and surprising.

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.

(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.

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.
