atomic particles, but all reality, he said, fell under its sway. “We have been forced to recognize that we must modify not only all our concepts of classical physics but even the ideas we use in everyday life,” he said. He had lately been meeting with Professor Einstein (their discussions were actually more discordant than Bohr now let on), and they had found no way out. “We have to renounce a description of phenomena based on the concept of cause and effect.”
Elsewhere amid the throngs at the fairground that summer, enduring the stifling heat, were Melville, Lucille, Richard, and Joan Feynman. For the occasion Joan had been taught to eat bacon with a knife and fork; then the Feynmans strapped suitcases to the back of a car and headed off crosscountry, a seemingly endless drive on the local roads of the era before interstate highways. On the way they stayed at farmhouses. The fair spread across four hundred acres on the shore of Lake Michigan, and the emblems of science were everywhere. Progress indeed: the fair celebrated a public sense of science that was reaching a crest. Knowledge Is Power —that earnest motto adorned a book of Richard’s called The Boy Scientist . Science was invention and betterment; it changed the way people lived. The eponymous business enterprises of Edison, Bell, and Ford were knotting the countryside with networks of wire and pavement—an altogether positive good, it seemed. How wonderful were these manifestations of the photon and the electron, lighting lights and bearing voices across hundreds of miles!
Even in the trough of the Depression the wonder of science fueled an optimistic faith in the future. Just over the horizon were fast airships, half-mile-high skyscrapers, and technological cures for diseases of the human body and the body politic. Who knew where the bright young students of today would be able to carry the world? One New York writer painted a picture of his city fifty years in the future: New York in 1982 would hold a magnificent fifty million people, he predicted, the East River and much of the Hudson River having been “filled in.” “Traffic arrangements will no doubt have provided for several tiers of elevated roadways and noiseless railways—built on extended balconies flanking the enormous skyscrapers …” Nourishment will come from concentrated pellets. Ladies’ dress will be streamlined to something like the 1930s bathing suit. The hero of this fantasy was the “high-school genius (who generally knows more than anybody else).” There was no limit to the hopes vested in the young.
Scientists, too, struggled to assimilate the new images pouring into the culture from the laboratory. Electricity powered the human brain itself, a University of Chicago researcher announced that summer; the brain’s central switchboard used vast numbers of connecting lines to join brain cells, each one of which could be considered both a tiny chemical factory and electric battery. Chicago’s business community made the most of these symbols, too. In an opening-day stunt, technicians at four astronomical observatories used faint rays of starlight from Arcturus, forty light-years distant, focused by telescopes and electrically amplified, to turn on the lights of the exposition. “Here are gathered the evidences of man’s achievements in the realm of physical science, proofs of his power to prevail over all the perils that beset him,” declared Rufus C. Dawes, president of the fair corporation, as loud projectiles released hundreds of American flags in the sky over the fairgrounds. Life-size dinosaurs awed visitors. A robot gave lectures. Visitors less interested in science could pay to see an unemployed actress named Sally Rand dance with ostrich-feather fans. The Feynmans, though, took the Sky Ride, suspended on cables between two six-hundred-foot towers, and visited the Hall of Science, where a 151-word wall motto summed up the history of science from Pythagoras to
