“I know this goes without saying, but Stonehenge really was the most incredible accomplishment. It took five hundred men just to pull each sarsen, plus a hundred more to dash around positioning the rollers. Just think about it for a minute. Can you imagine trying to talk six hundred people into helping you drag a fifty-ton stone eighteen miles across the countryside and muscle it into an upright position, and then saying, 'Right, lads! Another twenty like that, plus some lintels and maybe a couple of dozen nice bluestones from Wales, and we can party!' Whoever was the person behind Stonehenge was one dickens of a motivator, I'll tell you that.”

“If you drive to, say, Shenandoah National Park, or the Great Smoky Mountains, you'll get some appreciation for the scale and beauty of the outdoors. When you walk into it, then you see it in a completely different way. You discover it in a much slower, more majestic sort of way.”

“The first book I did - the first successful book - was a kind of a travel book, and publishers in Britain encouraged me to do more.”

“All the things that are part of your heritage make you British - that makes this country what it is. It's part of your history. And here, unlike America, it's still living history.”

“Open your refrigerator door, and you summon forth more light than the total amount enjoyed by most households in the 18th century. The world at night, for much of history, was a very dark place indeed.”

“We forget just how painfully dim the world was before electricity. A candle, a good candle, provides barely a hundredth of the illumination of a single 100 watt light bulb.”

“There'd never been a more advantageous time to be a criminal in America than during the 13 years of Prohibition. At a stroke, the American government closed down the fifth largest industry in the United States - alcohol production - and just handed it to criminals - a pretty remarkable thing to do.”

“There are only three things that can kill a farmer: lightning, rolling over in a tractor, and old age.”

“You don't need a science degree to understand about science. You just need to think about it.”

“An awful lot of England is slowly eroding, in ways that I find really distressing, and an awful lot of it is the hedgerows... We're reaching the point where a lot of the English countryside looks just like Iowa - just kind of open space.”

“I love to watch cities wake up, and Paris wakes up more abruptly, more startlingly, than any place I know.”
