| | |  Ames Laboratory: Encyclopedia II - Sunnyvale California - HistoryWhen the Spanish first arrived in the 1770s at the Santa Clara Valley, it was heavily populated by the Ohlone. In 1777, Mission Santa Clara was built by Ohlone converts to Christianity.
In 1842, Rancho Pastoria de las Borregas was granted to Estrada and Inez Castro. Portions of the land given in this grant later developed into the cities of Mountain View and Sunnyvale. Two years later, in 1844, another land grant was provided to Lupe Yñigo, one of the few Native Americans to hold land grants. His land grant was first called See also: Sunnyvale California, Sunnyvale California - Geography, Sunnyvale California - History, Sunnyvale California - Demographics, Sunnyvale California - Facts and trivia Read more here: » Sunnyvale California: Encyclopedia II - Sunnyvale California - History |

| | | | Ames Laboratory: Encyclopedia II - Manhattan Project - 1900s-1939: Nuclear physics and international politics After the discovery of the electron and radioactivity, at the start of the twentieth century the atom was no longer thought to be indivisible. In 1905 Albert Einstein showed in his theory of Special Relativity that a small amount of mass could be converted into a large amount of energy, though the practical significance of his E=mc2 equation was not fully appreciated for many years.
In 1911 Ernest Rutherford demonstrated that the majority of an atom's mass was in a small nucleus made up of protons that was surrounded by a c ...

| | | | Ames Laboratory: Encyclopedia II - Manhattan Project - Similar efforts A similar effort was undertaken in the USSR headed by Igor Kurchatov (with a specific difference in that some of Kurchatov's World War II investigations came secondhand from Manhattan Project countries, thanks to spies, including at least two on the scientific team at Los Alamos, Klaus Fuchs and Theodore Hall, unknown to each other).
After the MAUD Committee's report, the British and Americans exchanged nuclear information, but initally did not pool their efforts. A separate British project, code-named TUBE ALLOYS, was started but did ...

| | | | Ames Laboratory: Encyclopedia II - Manhattan Project - The plutonium bomb In contrast, the bombs used in the first test at Trinity Site, New Mexico (the gadget of the Trinity test), and also in the Nagasaki bomb, Fat Man, were made primarily of Plutonium-239. Plutonium is a synthetic element.
Although uranium-238 is useless as fissile material for an atomic bomb, U-238 is used to produce plutonium. The fission of U-235 produces relatively slow neutrons which will be absorbed by U-238, which after a few days of decay, turns into plutonium-239. The production and purification of plutonium used techniques deve ...

| | | | Ames Laboratory: Encyclopedia II - Manhattan Project - The Manhattan Engineering District In the summer of 1942, Col. Leslie Groves was deputy to the chief of construction for the Army Corps of Engineers and had overseen construction of the Pentagon, the world's largest office building. Hoping for an overseas command, Groves vigorously objected when Somervell appointed him to take charge of the weapons project. His objections were overruled and Groves resigned himself to leading a project he thought had little chance of succeeding. Groves appointed Oppenheimer as the project's scientific director, to the surprise of many. (Oppenh ...

| | | | Ames Laboratory: Encyclopedia II - Manhattan Project - The uranium bomb The Hiroshima bomb, Little Boy, was made from uranium-235, a rare isotope of uranium that has to be physically separated from more prevalent uranium-238 isotope, which is not suitable for use in an explosive device. However U-235 is only 0.7% of raw uranium and chemically identical to the 99.3% of U-238, so various physical methods were considered for separation.
One method of separating uranium 235 from raw uranium ore was devised by Franz Simon and Nicholas Kurti, two more Jewish emigrés, at Oxford University. Their method using ga ...

On January 16, 1939, Niels Bohr of Copenhagen, Denmark, arrived in the United States to spend several months in Princeton, New Jersey, and was particularly anxious to discuss some abstract problems with Albert Einstein. (Four years later Bohr was to escape to Sweden from Nazi-occupied Denmark in a small boat, along with thousan ...
