At the foot of the mountain, the park ended and suddenly all was squalor again. I was once more struck by this strange compartmentalization that goes on in America -- a belief that no commercial activities must be allowed inside the park, but permitting unrestrained development outside, even though the landscape there may be just as outstanding. America has never quite grasped that you can live in a place without making it ugly, that beauty doesn't have to be confined behind fences, as if a national park were a sort of zoo for nature.

I really enjoy going to a library and spending the day doing research - to me that is the most pleasurable part of writing the science book.

18th century scientists, the French in particular, seldom did things simply if an absurdly demanding alternative was available.

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

At a conference of sociologists in America in 1977, love was defined as "the cognitive-affective state characterized by intrusive and obsessive fantasizing concerning reciprocity of amorant feelings by the object of the amorance." That is jargon - the practice of never calling a spade a spade when you might instead call it a manual earth-restructuring implement - and it is one of the great curses of modern English.

I hadn't realized quite how extraordinary Charles Lindbergh's achievement was in flying the Atlantic alone. He had never flown over open water before, but he flew straight to Dingle Bay in Ireland and then on to Paris, exactly as planned.

In the morning I awoke early and experienced that sinking sensation that overcomes you when you first open your eyes and realize that instead of a normal day ahead of you, with its scatterings of simple gratifications, you are going to have a day without even the tiniest of pleasures; you are going to drive across Ohio.
