Tune your television to any channel it doesn't receive and about 1 percent of the dancing static you see is accounted for by this ancient remnant of the Big Bang. The next time you complain that there is nothing on, remember that you can always watch the birth of the universe.

I'm definitely an American, because I grew up here. But I've lived very happily in Britain.

Protons give an atom its identity, electrons its personality.

Very little of what America does is actually bad, and I don't think it ever does anything anywhere that is intentionally bad. I mean, sometimes we make mistakes and bad judgments and kind of back the wrong regimes and things, but by and large what America does is really good.

Think of a single problem confronting the world today. Disease, poverty, global warming... If the problem is going to be solved, it is science that is going to solve it. Scientists tend to be unappreciated in the world at large, but you can hardly overstate the importance of the work they do. If anyone ever cures cancer, it will be a guy with a science degree. Or a woman with a science degree.

I love the feeling of being anonymous in a city I've never been before.

England was full of words I'd never heard before - streaky bacon, short back and sides, Belisha beacon, serviettes, high tea, ice-cream cornet.
