Genius_ The Life and Science of Richard Feynman - James Gleick [27]
Occasionally Richard went on dates with other girls. He could never rid himself of a sense that he was a stranger engaging in a ritual the rules to which he did not know. His mother taught him some basic manners. Even so, the waiting in a girl’s parlor with her parents, the procedures for cutting in at dances, the stock phrases (“Thank you for a lovely evening”) all left him feeling inept, as if he could not quite decipher a code everyone else had mastered.
He stayed not quite conscious of the hopes his parents had for him. He was not quite aware of the void left by the death of his infant brother—his mother still thought of the baby often—or of his mother’s social descent to the lower middle class, in increasingly tight circumstances. With the coming of the Depression the Feynmans had to give up the house and yard on New Broadway and move to a small apartment, where they used a dining room and a breakfast room as bedrooms. Melville was often on the road now, selling. When he was home, he would read the National Geographic magazines that he collected secondhand. On Sundays he would go outdoors and paint woodland scenery or flowers. Or he and Richard would take Joan into the city to the Metropolitan Museum of Art. They went to the Egyptian section, first studying glyphs in the encyclopedia so that they could stand and decode bits of the chiseled artifacts, a sight that made people stare.
Richard still had some tinkering and probing to do. The Depression broadened the market for inexpensive radio repair, and Richard found himself in demand. In just over a decade of full-scale commercial production, the radio had penetrated nearly half of American households. By 1932 the average price of a new set had fallen to $48, barely a third of the price just three years before. “Midget” sets had arrived, just five tubes compactly arranged within an astonishing six-pound box, containing its own built-in aerial and a shrunken loudspeaker the size of a paper dollar. Some receivers offered knobs that would let the user adjust the high and low tones separately; some advertised high style, like the “satin-finished ebony black Durez with polished chromium grille and trimmings.”
Broken radios confronted Richard with a whole range of pathologies in the circuits he had learned so well. He rewired a plug or climbed a neighbor’s roof to install an antenna. He looked for clues, wax on a condenser or telltale charcoal on a burned-out resistor. Later he made a story out of it—“He Fixes Radios by Thinking!” The hero was an exaggeratedly young boy, with a comically large screwdriver sticking out of his back pocket, who solved an ever-more-challenging sequence of puzzles. The last and best broken radio—the one that established his reputation—made a bloodcurdling howl when first turned on. Richard paced back and forth, thinking, while the curmudgeonly owner badgered him: “What are you doing? Can you fix it?” Richard thought about it. What could be making a noise that changed with time? It must have something to do with the heating of the tubes—first some extraneous signal was swollen into a shriek; then it settled back to normal. Richard stopped pacing, went back to the set, pulled out one tube, pulled out a second tube, and exchanged them. He turned on the set, and the noise had vanished. The boy who fixes radios by thinking—that was how he saw himself, reflected in the eyes of his customers in Far Rockaway. Reason worked. Equations could be trusted; they were more than schoolbook exercises. The heady rush of solving a puzzle, of feeling the mental pieces shift and fade and rearrange themselves until suddenly they slid into their grooves—the sense of power and sheer rightness—these pleasures sustained an addiction. Luxuriating in the buoyant joy of it,
