The history of the development of the atomic bomb

The English phrase MAD was often known by, "nuclear deterrence," was translated by the French as "dissuasion," and "terrorization" by the Soviets.

The initial problem for the Soviets was primarily one of resources—they had not scouted out uranium resources in the Soviet Union and the U. It also encouraged the production of thousands of nuclear weapons by both the U. This created concern within the U. The Cold War arms race had begun, and nuclear testing and research became high-profile goals for several countries, especially the United States and the Soviet Union.

If the Soviet Union also had nuclear weapons and a policy of "massive retaliation" was carried out, it was reasoned, then any Soviet forces not killed in the initial attack, or launched while the attack was ongoing, would be able to serve their own form of nuclear retaliation against the U.

During the war, information had been pouring in from a number of volunteer spies involved with the Manhattan Project known in Soviet cables under the code-name of Enormozand the Soviet nuclear physicist Igor Kurchatov was carefully watching the Allied weapons development.

In American politics this translated into demands to avoid " bomber gaps " and " missile gaps " where the Soviet Union could potentially outshoot the Americans. MAD played on two seemingly opposed modes of thought: India was the first country outside of the NPT to test a nuclear weapon in According to game theory, because starting a nuclear war was suicidal, no logical country would shoot first.

Max Planckof Germany, who established the law of radiation, which led to the theory of quanta and the modern understanding of the electronic structure of matter. In the fall of Harold C.

It somehow got into a document that went to Washington" and was "never laid to rest". William Konrad Roentgena German professor, whose discovery of X-rays provided for science a revolutionary tool.

In Augustconcerned that Germany might have its own project to develop fission-based weapons, Albert Einstein signed a letter to U. The other was a program of miniaturization, reducing the size of the nuclear weapons.

Deterrence and brinkmanship[ edit ] Main articles: From them came the realization that the atom has a core, or nucleus, quite different from the shell of the atom. Otto Hahn and Dr. It was the first U. North Korea tested two long-range intercontinental ballistic missiles in —one reportedly capable of reaching the United States mainland.

Because of the difficulties in making a working plutonium bomb, it was decided that there should be a test of the weapon. A ton bomb was exploded some yards from the Trinity site where Gadget would be detonated a few weeks later. The notion of using a fission weapon to ignite a process of nuclear fusion can be dated back to Weapons improvement[ edit ] The introduction of nuclear-tipped rockets, like the MGR-1 Honest Johnreflected a change in both nuclear technology and strategy.

The Soviets vetoed the plan, effectively ending any immediate postwar negotiations on atomic energy, and made overtures towards banning the use of atomic weapons in general.

Smaller bombs meant that bombers could carry more of them, and also that they could be carried on the new generation of rockets in development in the s and s. South Sudan is not known or believed to possess nuclear weapons. Oppenheimer, who was now head of the General Advisory Committee of the successor to the Manhattan Project, the Atomic Energy Commission, presided over a recommendation against the development of the weapon.In Maythe Allies defeated Germany, two months before the atomic bomb was complete.

War with Japan continued, however, and In August it seemed that an invasion of Japan itself might be necessary to force the Japanese to surrender.

The Manhattan Project was named for Columbia University in Manhattan, New York, one of the initial sites of atomic study in the United States. While the research took place at several secret sites across the U.S., much of it, including the first atomic tests, took place near Los Alamos, New Mexico.

Atomic Archive — Explore the History, Science, and Consequences of the Atomic Bomb There is so much information at this site; biographies, photographs, current nuclear data, fission and fusion, a timeline, that it's hard not to find what you are looking for at.

The resulting Manhattan Project absorbed $2,, of the $3,, spent by the United States on R and D in World War II. Churchill, too, approved a nuclear program, code-named the Directorate of Tube Alloys, in Britain’s dark days of Dr.

J. Robert Oppenheimer arrived at Los Alamos in March to take charge of the development of the atomic bomb. From Los Alamos came the design of the implosion bomb and treatment of many theoretical problems. Methods of purifying materials to be used were developed.

51f. The Manhattan Project

Finally, in July,a practical atomic bomb was completed. The Japanese bombing of Pearl Harbor on December 7,accelerated the development of an atomic bomb in the United States. In the spring of the decision was made to consolidate development activities in Chicago.

Manhattan Project

The objective was to produce a nuclear chain reaction by the end of the year.
