Manhattan project what were the social and cultural effects of the development of the nuclear bomb

The explosion came as an intense light flash, a sudden wave of heat, and later a tremendous roar as the shock wave passed and echoed in the valley. The first atomic bomb was exploded at 5: After the atomic bombings of Japan, many scientists at Los Alamos rebelled against the notion of creating a weapon thousands of times more powerful than the first atomic bombs.

Extremely harmful fission products would disperse via normal weather patterns and embed in soil and water around the planet. This had massive political and cultural effects during the Cold War.

The signatories included eleven pre-eminent intellectuals and scientists, including Albert Einsteinwho signed it just days before his death on April 18, Methods of rapidly bringing together amounts of fissionable material to achieve a supercritical mass and thus a nuclear explosion had to be devised, along with the actual construction of a deliverable weapon that would be dropped from a plane and fused to detonate at the proper moment in the air above the target.

At this point, however, the exact mechanism was still not known: This massive site provides loads of information to help you reach your own conclusions. The Manhattan Project Here is a month-by-month detailed account of the status of the atomic bomb leading up to the detonation of "Gadget" in the deserts of Alamogordo, New Mexico in July, At the first major theoretical conference on the development of an atomic bomb hosted by J.

Manhattan Project

In operations like Chrome DomeSAC kept nuclear-armed planes in the air 24 hours a day, ready for an order to attack Moscow. Electromagnetic U separation plant at Oak Ridge, Tenn. Neither the Germans nor the Japanese could learn of the project. The device was a prototype design and not a deliverable weapon: Britain and the U.

Many of these companies had very lax safety measures and employees were sometimes exposed to radiation levels far above what was allowed then or now. Inall nuclear and many non-nuclear states signed the Limited Test Ban Treatypledging to refrain from testing nuclear weapons in the atmosphere, underwater, or in outer space.

Planners reasoned that conventional command and control systems could not adequately react to a nuclear attack, so great lengths were taken to develop computer systems that could look for enemy attacks and direct rapid responses.

51f. The Manhattan Project

Roosevelt saw neither the necessity nor the utility for such a project, but agreed to proceed slowly. Robert Oppenheimer working on the Manhattan Project.

Scientific development was centralized in a secret laboratory at Los Alamos. The "secret cities" used for the Soviet equivalents of Hanford and Oak Ridge literally vanished from the maps for decades to come. It was assumed that the uranium gun-type bomb could then be adapted from it.

The object of a country operating by the MAD doctrine is to deny the opposing country this first strike capability. Efforts were made to recover the cargo of contaminated fish but at least two large tuna were probably sold and eaten.

According to game theory, because starting a nuclear war was suicidal, no logical country would shoot first. In the first decades of the 20th century, physics was revolutionised with developments in the understanding of the nature of atoms.

Philip Hauge Abelson developed a third method called thermal diffusion, which was also used for a time to effect a preliminary separation. At the Soviet equivalent of Los Alamos, Arzamasphysicist Yuli Khariton led the scientific effort to develop the weapon.

Working under a stubborn and scientifically ignorant administrator, the Soviet scientists struggled on. First strike meant the first use of nuclear weapons by one nuclear-equipped nation against another nuclear-equipped nation. Beria distrusted his scientists, however, and he distrusted the carefully collected espionage information.

The Castle Bravo incident itself raised a number of questions about the survivability of a nuclear war. Beria used the espionage information as a way to double-check the progress of his scientists, and in his effort for duplication of the American project even rejected more efficient bomb designs in favor of ones that more closely mimicked the tried-and-true Fat Man bomb used by the U.

The reasons were in part because the success of the technology seemed limited at the time and not worth the investment of resources to confirm whether this was soand because Oppenheimer believed that the atomic forces of the United States would be more effective if they consisted of many large fission weapons of which multiple bombs could be dropped on the same targets rather than the large and unwieldy super bombs, for which there was a relatively limited number of targets of sufficient size to warrant such a development.

In American politics this translated into demands to avoid " bomber gaps " and " missile gaps " where the Soviet Union could potentially outshoot the Americans. It is the result of a test investigating whether nuclear weapons could be used to excavate canals and harbors.

Images of the important figures, bomb-manufacturing plants, and explosions make this site a to see. In the end, President Truman made the final decision, looking for a proper response to the first Soviet atomic bomb test in This laboratory had to develop methods of reducing the fissionable products of the production plants to pure metal and fabricating the metal to required shapes.

They concluded that, while Germany had an atomic bomb program headed by Werner Heisenbergthe government had not made a significant investment in the project, and it had been nowhere near success. Recognizing that this was an undesirable outcome, military officers and game theorists at the RAND think tank developed a nuclear warfare strategy that was eventually called Mutually Assured Destruction MAD.

After hearing arguments from scientists and military officers over the possible use of nuclear weapons against Japan though some recommended using them as demonstrations in unpopulated areas, most recommended using them against built up targets, a euphemistic term for populated citiesTruman ordered the use of the weapons on Japanese cities, hoping it would send a strong message that would end in the capitulation of the Japanese leadership and avoid a lengthy invasion of the islands.The Manhattan Project and Its Legacy.

Table of Contents Just as expert and multifaceted were museum professionals from Manhattan Project historic sites, the Smithsonian Institution, and science museums; interpretation specialists from the National Transforming the Relationship Between Science and Society.

History of nuclear weapons. Jump to navigation Jump to search. A the Manhattan project brought together some of the top scientific minds of the day, to prevent the other power from acquiring nuclear supremacy. This had massive political and cultural effects during the Cold War.

Major General Leslie Groves oversaw the Manhattan Project for the US government. Private corporations, foremost among them DuPont, helped prepare weapons-grade uranium and other components needed to make the bombs. Nuclear materials were processed in reactors located in Oak Ridge, Tennessee and Hanford, Washington.

As with the decision to drop the bomb, teachers can organize their class into groups and have them debate the issue of atomic weapons and the effects of nuclear energy.

Have students begin to outline some of the social and political changes that resulted from the Manhattan Project. the war department in the Manhattan Project to develop an atomic bomb. After four years of intensive and ever-mounting research and development efforts, an atomic device was set off on July 16,in a desert area near Alamogordo, New Mexico, generating an explosive power equivalent to that of more.

The Manhattan Project was the Allied effort to develop the atomic bomb during World War II. Led by Maj.

Gen. Leslie Groves and J. Robert Oppenheimer, it developed research facilities across the United States. The Project was successful and made the atomic bombs used at Hiroshima and Nagasaki. On.
