Becoming a Scientist

Teaching science, you become interested in accounts of how kids grow up to become scientists. The best of these accounts are Richard Feynman’s Surely You’re Joking, Mr. Feynman, and, in my view, Gerald Durrell’s My Family and Other Animals. Together, they seem to outline the two sides of science, quantitative and qualitative, science as thinking and science as seeing. The two memoirs make no pretense that their authors’ interests and, to a large extent their adult abilities were not largely innate. At the same time, the full development of those abilities hinged partly- in Feynman’s case- on a father determined to make his son a scientist and a New York City neighborhood full of radios to fix and clever people to talk with, and-in Durrell’s case- on the island of Corfu with its many animals and a scientist and naturalist (Theodore Stephanides) eager to mentor him.

For both writers, it seems clear that science was not an isolated obsession but instead a particularly interesting section of a broader stream of life.

Here are two sections from early in each book:


From My Family and Other Animals, “The Strawberry Pink Villa”

For myself, the garden held sufficient interest; together Roger and I learnt some surprising things. Roger, for example, found that it was unwise to smell hornets, that the peasant dogs ran screaming if he glanced at them through the gate, and that the chickens that leapt suddenly from the fuchsia hedge, squawking wildly as they fled, were unlawful prey, however desirable.
This doll’s-house garden was a magic land, a forest of flowers through which roamed creatures I had never seen before. Among the thick, silky petals of each rose-bloom lived tiny, crab-like spiders that scuttled sideways when disturbed. Their small, translucent bodies were coloured to match the flowers they inhabited: pink, ivory, wine-red, or buttery-yellow. On the rose-stems, encrusted with green flies, lady-birds moved like newly painted toys; lady-birds pale red with large black spots; lady-birds apple-red with brown spots; lady-birds orange with grey-and-black freckles. Rotund and amiable, they prowled and fed among the anaemic flocks of greenfly. Carpenter bees, like furry, electric-blue bears, zigzagged among the flowers, growling fatly and busily. Humming-bird hawk-moths, sleek and neat, whipped up and down the paths with a fussy efficiency, pausing occasionally on speed-misty wings to lower a long, slender proboscis into a bloom. Among the white cobbles large black ants staggered and gesticulated in groups round strange trophies: a dead caterpillar, a piece of rose-petal, or dried grass-head fat with seeds. As an accompaniment to all this activity there came from the olive-groves outside the fuchsia hedge the incessant shimmering cries of the cicadas. If the curious, blurring heat-haze produced a sound, it would be exactly the strange, chiming cries of these insects.

At first I was so bewildered by this profusion of life on our very doorstep that I could only move about the garden in a daze, watching now this creature, now that, constantly having my attention distracted by the flights of brilliant butterflies that drifted over the hedge. Gradually, as I became more used to the bustle of insect life among the flowers, I found I could concentrate more. I would spend hours squatting on my heels or lying on my stomach watching the private lives of the creatures around me, while Roger sat nearby, a look of resignation on his face. In this way I learnt a lot of fascinating things.

I found that the little crab-spiders could change colour just as successfully as any chameleon. Take a spider from a wine-red rose, where he had been sitting like a bead of coral, and place him in the depths of a cool white rose. If he stayed there – and most of them did – you would see his colour gradually ebb away, as though the change had given him anaemia, until, some two days later, he would be crouching among the white petals like a pearl.

I discovered that in the dry leaves under the fuchsia hedge lived another type of spider, a fierce little huntsman with the cunning and ferocity of a tiger. He would stalk about his continent of leaves, eyes glistening in the sun, pausing now and then to raise himself up on his hairy legs to peer about. If he saw a fly settle to enjoy a sun-bath he would freeze; then, as slowly as a leaf growing, he would move forward, imperceptibly, edging nearer and nearer, pausing occasionally to fasten his life-line of silk to the surface of the leaves. Then, when close enough, the huntsman would pause, his legs shift minutely as he got a good purchase, and then he would leap, legs spread out in a hairy embrace, straight on to the dreaming fly. Never did I see one of these little spiders miss its kill, once it had manoeuvred into the right position.

All these discoveries filled me with a tremendous delight, so that they had to be shared, and I would burst suddenly into the house and startle the family with the news that the strange, spiky black caterpillars on the roses were not caterpillars at all, but the young of lady-birds, or with the equally astonishing news that lacewing-flies laid eggs on stilts.


From Surely You’re Joking, Mr. Feynman, “He Fixes Radios by Thinking!”

WHEN I WAS about eleven or twelve I set up a lab in my house. It consisted of an old wooden packing box that I put shelves in. I had a heater, and I’d put in fat and cook french-fried potatoes all the time. I also had a storage battery, and a lamp bank.
To build the lamp bank I went down to the five-and-ten and got some sockets you can screw down to a wooden base, and connected them with pieces of bell wire. By making different combinations of switches —in series or parallel—I knew I could get different voltages. But what I hadn’t realized was that a bulb’s resistance depends on its temperature, so the results of my calculations weren’t the same as the stuff that came out of the circuit. But it was all right, and when the bulbs were in series, all half-lit, they would gloooooooooow, very pretty—it was great!
I had a fuse in the system so if I shorted anything, the fuse would blow. Now I had to have a fuse that was weaker than the fuse in the house, so I made my own fuses by taking tin foil and wrapping it around an old burnt-out fuse. Across my fuse I had a five-watt bulb, so when my fuse blew, the load from the trickle charger that was always charging the storage battery would light up the bulb. The bulb was on the switchboard behind a piece of brown candy paper (it looks red when a light’s behind it) —so if something went off, I’d look up to the switchboard and there would be a big red spot where the fuse went. It was fun!
I enjoyed radios. I started with a crystal set that I bought at the store, and I used to listen to it at night in bed while I was going to sleep, through a pair of earphones. When my mother and father went out until late at night, they would come into my room and take the earphones off—and worry about what was going into my head while I was asleep.
About that time I invented a burglar alarm, which was a very simple-minded thing: it was just a big battery and a bell connected with some wire. When the door to my room opened, it pushed the wire against the battery and closed the circuit, and the bell would go off.
One night my mother and father came home from a night out and very, very quietly, so as not to disturb the child, opened the door to come into my room to take my earphones off. All of a sudden this tremendous bell went off with a helluva racket—BONG BONG BONG BONG BONG!!! I jumped out of bed yelling, “It worked! It worked!”
I had a Ford coil—a spark coil from an automobile—and I had the spark terminals at the top of my switchboard. I would put a Raytheon RH tube, which had argon gas in it, across the terminals, and the spark would make a purple glow inside the vacuum —it was just great!
One day I was playing with the Ford coil, punching holes in paper with the sparks, and the paper caught on fire. Soon I couldn’t hold it any more because it was burning near my fingers, so I dropped it in a metal wastebasket which had a lot of newspapers in it. Newspapers burn fast, you know, and the flame looked pretty big inside the room. I shut the door so my mother—who was playing bridge with some friends in the living room—wouldn’t find out there was a fire in my room, took a magazine that was lying nearby, and put it over the wastebasket to smother the fire.
After the fire was out I took the magazine off, but now the room began to fill up with smoke. The wastebasket was still too hot to handle, so I got a pair of pliers, carried it across the room, and held it out the window for the smoke to blow out.
But because it was breezy outside, the wind lit the fire again, and now the magazine was out of reach. So I pulled the flaming wastebasket back in through the window to get the magazine, and I noticed there were curtains in the window—it was very dangerous!
Well, I got the magazine, put the fire out again, and this time kept the magazine with me while I shook the glowing coals out of the wastepaper basket onto the street, two or three floors below. Then I went out of my room, closed the door behind me, and said to my mother, “I’m going out to play,” and the smoke went out slowly through the windows.
