“On the dashboard of our family car is a shallow indentation about the size of a paperback book. If you are looking for somewhere to put your sunglasses or spare change, it is the obvious place, and it works extremely well,”

Time, you discover, has wrought changes that leave you feeling mildly foolish and out of touch.

Those who sniff decay in every shift of sense or alteration of usage do the language no service. Too often for such people the notion of good English has less to do with expressing ideas clearly than with making words conform to some arbitrary pattern.

Don’t you believe it. Bacteria may not build cities or have interesting social lives, but they will be here when the Sun explodes. This is their planet, and we are on it only because they allow us to be.

Your pillow alone may be home to 40 million bed mites. (To them your head is just one large oily bon-bon). And don’t think a clean pillow-case will make a difference…

When the Duke [W.J.C. Scott-Bentinck] died, his heirs found all of the aboveground rooms devoid of furnishings except for one chamber in the middle of which sat the Duke’s commode. The main hall was mysteriously floor less. Most of the rooms were painted pink.

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.

My favourite fellow of the Royal Society is the Reverend Thomas Bayes, an obscure 18th-century Kent clergyman and a brilliant mathematician who devised a complex equation known as the Bayes theorem, which can be used to work out probability distributions.

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.

Ordnance Survey maps, tea and crumpets, summer showers and foggy winter evenings – every bit of it.

So that buildings and structures you normally pass without a glance suddenly become arresting, even beautiful? Well, they seem to have that light in Australia nearly all the time.

I love everything about motels. I can’t help myself. I still get excited every time I slip a key into a motel room door and fling it open.

When you sit in a chair, you are not actually sitting there, but levitating above it at a height of one angstrom (a hundred millionth of a centimetre), your electrons and its electrons implacably opposed to any closer intimacy.

It is a slightly arresting notion that if you were to pick yourself apart with tweezers, one atom at a time, you would produce a mound of fine atomic dust, none of which had ever been alive but all of which had once been you.

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.

If a potato can produce vitamin C, why can’t we? Within the animal kingdom only humans and guinea pigs are unable to synthesize vitamin C in their own bodies. Why us and guinea pigs? No point asking. Nobody knows.

But I got a great deal else from the experience. I learned to pitch a tent and sleep beneath the stars. For a brief, proud period I was slender and fit. I gained a profound respect for the wilderness and nature and the benign dark power of woods.

You laugh, but you haven’t seen me in a tux. Or maybe you don’t like broad-shouldered guys with muscular chest and washboard abs?
