World War II Begins
World War II began with the German invasion of Poland on September 1, 1939, prompting Albert Einstein and Leó Szilárd to complete the letter to U.S. President Franklin Delano Roosevelt they had been working on over the summer. This letter was signed by Einstein on August 2, and it was hand-delivered to Roosevelt by the economist Alexander Sachs on October 11, 1939. The letter advised Roosevelt of the existence of the German nuclear energy project and warned that it was likely the Germans were working on an atomic bomb using uranium, and that the U.S. should be concerned about locating sources of uranium and researching nuclear weapon technology. At this time the U.S. policy was neutral in the war.
Experiments with the fission of uranium were already going on at universities and research institutes in the United States. Alfred Lee Loomis was supporting Ernest Lawrence at Berkeley Radiation Laboratory and Enrico Fermi at Columbia. Vannevar Bush was also doing similar research at Washington, D.C.-based Carnegie Institution. After the April 29, 1940 spring meeting of the American Physical Society, the New York Times reported that conferees argued "the probability of some scientist blowing up a sizable portion of the earth with a tiny bit of uranium."

Famous quotes containing the words world, war and/or begins:
“My uncle Toby had scarce a heart to retalliate upon a fly.
Go,—says he, one day at dinner, to an over-grown one which had buzz’d about his nose ... go poor Devil, get thee gone, why should I hurt thee?—This world surely is wide enough to hold both thee and me.”
—Laurence Sterne (1713–1768)
“War is bestowed like electroshock on the depressive nation; thousands of volts jolting the system, an artificial galvanizing, one effect of which is loss of memory. War comes at the end of the twentieth century as absolute failure of imagination, scientific and political. That a war can be represented as helping a people to “feel good” about themselves, their country, is a measure of that failure.”
—Adrienne Rich (b. 1929)
“In order for an individual to partake of the world and contribute to it in a healthy way, he first needs to view that world as a basically kind, friendly, and supportive place. Such an outlook begins to be formed during infancy. It’s essential that the baby establish a fundamental trust in his environment. The infant needs to learn that the world is a nurturing place where his needs will be met.”
—Saf Lerman (20th century)
