Conditions worsened again for the Jews when the Empire was Christianized in the fourth century A.D. with the conversion of the Emperor Constantine; Christianity and Judaism competed, in a Darwinian sense, for the same Holy Land and the same holy books. Under systematic persecution only a small remnant of the Jewish people remained in Judea. The fantasy of Jews as a brotherhood of evil was invented during this era when Christianity fought its missionary way to dominance.

The English were the first to expel the Jews entirely. The Jews of England belonged to the Crown, which had systematically extracted their wealth through a special Exchequer to the Jews. By 1290 it had bled them dry. Edward I thereupon confiscated what little they had left and threw them out.

But the scurrilities of Mein Kampf, which on the evidence of their incoherence are not calculated manipulations but violent emotional outbursts, demonstrate that Hitler pathologically feared and hated the Jews. In black megalomania he masked an intelligent, industrious and much-persecuted people with the distorted features of his own terror. And that would make all the difference.

Universities were state institutions. Members of their faculties were therefore civil servants. The new law abruptly stripped a quarter of the physicists of Germany, including eleven who had earned or would earn Nobel Prizes, of their positions and their livelihood.676 It immediately affected some 1,600 scholars in all.677 Nor were academics dismissed by the Reich likely to find other work. To survive they would have to emigrate.

Theodor von Kármán departed first, from Aachen. He had pioneered aeronautical physics; the California Institute of Technology, then vigorously assembling its future reputation, wanted to include that specialty in its curriculum. Aviation philanthropist Daniel Guggenheim was prevailed upon to contribute. The Guggenheim Aeronautical Laboratory, with a tenfoot wind tunnel, began operation under von Kármán’s direction in 1930.

He introduced a new type of force, the “weak interaction,” completing the four basic forces known in nature: gravity and electromagnetism, which operate at long range, and the strong force and Fermi’s weak force, which operate within nuclear dimensions. He introduced a new fundamental constant, now called the Fermi constant, determining it from existing experimental data.

Bohr went on to say that the common aim of all science was “the gradual removal of prejudices,” a complementary restorative to the usual pious characterization of science as a quest for incontrovertible truth.

To a greater extent than any other scientist of the twentieth century Bohr perceived the institution of science to which he dedicated his life to be a profoundly political force in the world. The purpose of science, he believed, was to set men free. Totalitarianism, in Hannah Arendt’s powerful image, drove toward “destroying all space between men and pressing men against each other.”923 It was entirely in character that Bohr, at a time of increasing danger, publicly opposed that drive with the individualistic and enriching discretions of complementarity.

If the large uranium nucleus split into two smaller nuclei, the smaller nuclei would weigh less in total than their common parent. How much less? That was a calculation she could easily work: about one-fifth the mass of a proton less. Process one-fifth of the mass of a proton through E = mc2. “One fifth of a proton mass,” Frisch exclaims, “was just equivalent to 200 MeV. So here was the source for that energy; it all fitted!”992

Later that day Frisch looked me up and said, “You work in a microbiology lab. What do you call the process in which one bacterium divides into two?” And I answered, “binary fission.” He wanted to know if you could call it “fission” alone, and I said you could. Frisch the sketch artist, good at visualizing as his aunt was not, had metamorphosed his liquid drop into a dividing living cell.1016 Thereby the name for a multiplication of life became the name for a violent process of destruction.

When I heard this I immediately saw that these fragments, being heavier than corresponds to their charge, must emit neutrons, and if enough neutrons are emitted . . . then it should be, of course, possible to sustain a chain reaction.

Many years later Szilard succinctly summed up the difference between his position and Fermi’s. “From the very beginning the line was drawn,” he said. “ . . . Fermi thought that the conservative thing was to play down the possibility that [a chain reaction] may happen, and I thought the conservative thing was to assume that it would happen and take all the necessary precautions.”1082

Did this not mean that a nuclear explosive was certainly possible?” Not necessarily, Bohr countered.1123 “We tried to convince him,” Teller writes, “that we should go ahead with fission research but we should not publish the results. We should keep the results secret, lest the Nazis learn of them and produce nuclear explosions first. Bohr insisted that we would never succeed in producing nuclear energy and he also insisted that secrecy must never be introduced into physics.”1124

More crucial for Bohr was the issue of secrecy. He had worked for decades to shape physics into an international community, a model within its limited franchise of what a peaceful, politically united world might be. Openness was its fragile, essential charter, an operational necessity, as freedom of speech is an operational necessity to a democracy. Complete openness enforced absolute honesty: the scientist reported all his results, favorable and unfavorable, where all could read them, making possible the ongoing correction of error. Secrecy would revoke that charter and subordinate science as ...more

From the horrible weapon which they were about to urge the United States to develop, Szilard, Teller and Wigner—“the Hungarian conspiracy,” Merle Tuve was amused to call them—hoped for more than deterrence against German aggression.1194 They also hoped for world government and world peace, conditions they imagined bombs made of uranium might enforce.

One of Roosevelt’s first acts was to appeal to the belligerents to refrain from bombing civilian populations. Revulsion against the bombing of cities had grown in the United States since at least the Japanese bombing of Shanghai in 1937.1198 When Spanish Fascists bombed Barcelona in March 1938, Secretary of State Cordell Hull had condemned the atrocity publicly: “No theory of war can justify such conduct,” he told reporters. “ . . . I feel that I am speaking for the whole American people.”1199 In June the Senate passed a resolution condemning the “inhuman bombing of civilian populations.”

So although Roosevelt had asked Congress for increased funds for long-range bombers nine months before, in appealing to the belligerents on September 1, 1939, he could still articulate the moral indignation of millions of Americans:

Consistent with Martin Klaproth’s inspiration in 1789 to link his discovery of a new element with the recent discovery of the planet Uranus and with McMillan’s suggestion to extend the scheme to Neptune, Seaborg would name element 94 for Pluto, the ninth planet outward from the sun, discovered in 1930 and named for the Greek god of the underworld, a god of the earth’s fertility but also the god of the dead: plutonium.

“Bohr spoke highly of Compton as a physicist and a man,” a friend of the Danish laureate remembers, “but he felt that Compton’s philosophy was too primitive: ‘Compton would like to say that for God there is no uncertainty principle. That is nonsense. In physics we do not talk about God but about what we can know. If we are to speak of God we must do so in an entirely different manner.’ ”

Patriotism contributed to many decisions, but a deeper motive among the physicists, by the measure of their statements, was fear—fear of German triumph, fear of a thousand-year Reich made invulnerable with atomic bombs. And deeper even than fear was fatalism.

The United States was not yet committed to building an atomic bomb. But it was committed to exploring thoroughly whether or not an atomic bomb could be built. One man, Franklin Roosevelt, decided that commitment—secretly, without consulting Congress or courts. It seemed to be a military decision and he was Commander in Chief.

Isoroku Yamamoto, Commander in Chief of the Japanese Combined Fleet, had few illusions about the ultimate success of a war against the United States. He had studied at Harvard and served as a naval attaché in Washington and knew America’s strength. But if war had to come he meant “to give a fatal blow to the enemy fleet” when it was least expected, at the outset. By that act he hoped he could win his country six months to a year during which it might establish its Greater East Asia Co-Prosperity Sphere and dig in.

If time, not money, was the crucial issue—in Conant’s words, “if the possession of the new weapon in sufficient quantities would be a determining factor in the war”—then “three months’ delay might be fatal.” It followed that all five methods should be pushed at once, even though “to embark on this Napoleonic approach to the problem would require the commitment of perhaps $500,000,000 and quite a mess of machinery.”1582

But a few among the men and women gathered at Los Alamos—certainly Robert Oppenheimer—sniffed a paradox. They proposed in fact to win the war with an application of their science. They dreamed further that by that same application they might forestall the next war, might even end war as a means of settling differences between nations. Which must in the long run have decisive consequences, one way or the other, for nationalism.
