As Edward P. Tryon of Columbia University once put it: "In answer to the question of why it happened, I offer the modest proposal that our universe i… - Bill Bryson

Making models was reputed to be hugely enjoyable... But when you got the kit home and opened the box the contents turned out to be of a uniform leaden gray or olive green, consisting of perhaps sixty thousand tiny parts, some no larger than a proton, all attached in some organic, inseparable way to plastic stalks like swizzle sticks. The tubes of glue by contrast were the size of large pastry tubes. No matter how gently you depressed them they would blurp out a pint or so of a clear viscous goo whose one instinct was to attach itself to some foreign object—a human finger, the living-room drapes, the fur of a passing animal—and become an infinitely long string. Any attempt to break the string resulted in the creation of more strings. Within moments you would be attached to hundreds of sagging strands, all connected to something that had nothing to do with model airplanes or World War II. The only thing the glue wouldn’t stick to, interestingly, was a piece of plastic model; then it just became a slippery lubricant that allowed any two pieces of model to glide endlessly over each other, never drying. The upshot was that after about forty minutes of intensive but troubled endeavor you and your immediate surroundings were covered in a glistening spiderweb of glue at the heart of which was a gray fuselage with one wing on upside down and a pilot accidentally but irremediably attached by his flying cap to the cockpit ceiling. Happily by this point you were so high on the glue that you didn’t give a shit about the pilot, the model, or anything else.

As we parted at the Natural History Museum in London, I asked Richard Fortey how science ensures that when one person goes there's someone ready to take his place.

He chuckled rather heartily at my naiveté. 'I'm afraid it's not as if we have substitutes sitting on the bench somewhere waiting to be called in to play. When a specialist retires or, even more unfortunately, dies, that can bring a stop to things in that field, sometimes for a very long while.'

And I suppose that's why you value someone who spends forty-two years studying a single species of plant, even if it doesn't produce anything terribly new?'

'Precisely,' he said, 'precisely.' And he really seemed to mean it.

Of all the things I am not very good at, living in the real world is perhaps the most outstanding.
