Australians are very unfair in this way. They spend half of any conversation insisting that the country's dangers are vastly overrated and that there's nothing to worry about, and the other half telling you how six months ago their Uncle Bob was driving to Mudgee when a tiger snake slid out from under the dashboard and bit him on the groin, but that it's okay now because he's off the life support machine and they've discovered he can communicate with eye blinks.

When I awoke it was daylight. The inside of my tent was coated in a curious flaky rime, which I realized after a moment was all of my nighttime snores, condensed and frozen and pasted to the fabric, as if into a scrapbook of respiratory memories.

If you believe in god, it's much more fantastic to believe that he created this universe billions of years ago and set in motion this long train of activities that eventually resulted in us. I think that's so much more satisfying, more thrilling, than the idea that it was all done in seven days.

Traveling makes you realize what an immeasurably nice place much of America could be if only people possessed the same instinct for preservation as they do in Europe.

A significant fraction of thru-hikers reach Katahdin, then turn around and start back to Georgia. They just can't stop walking, which kind of makes you wonder.

I'm quite certain that if the rest of the world vanished overnight and the development of cricket were left in Australian hands, within a generation, the players would be wearing shorts and using the bats to hit each other, and the thing is, it'd be a much better game for it.

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.
