Why manhattan project is important

Resources: The Department has developed and made available to the public — in print, online, and on display — a variety of Manhattan Project historical resources , including histories, websites, reports, and document collections. The site is designed to disseminate information and documentation on the Manhattan Project to a broad audience including scholars, students, and the general public.

The Manhattan Project: Resources consists of two parts: 1 a multi-page, easy-to-read history providing a comprehensive overview of the Manhattan Project, and 2 the full-text, declassified, volume Manhattan District History commissioned by General Leslie Groves in late The new site brings together an enormous amount of material, much of it never before released.

The site features a timeline chronicling the road to the atomic bomb via East Tennessee, a K site tour where the visitor can "walk" through decades of skyline changes, a glimpse of daily life in the construction camp known as Happy Valley, and a preview at preservation efforts planned to commemorate the K Manhattan Project site. He was relentless," Wellerstein said. The Manhattan Project enlisted the help of thousands of scientists across the country. Enrico Fermi and Leo Szilard, physicists at the University of Chicago, were particularly important in the effort, Wellerstein said.

That's unusual, even now," Wellerstein said. These scientists all worked under J. One of the first steps of the project was to produce a chain reaction — a cascade of splitting atoms that can release enough energy to trigger an explosion. Not long after the Manhattan Project began, Enrico Fermi and Leo Szilard became the first scientists in the world to achieve that goal, according to the Atomic Heritage Foundation.

But the most sensitive research questions were explored at Los Alamos National Laboratory, "in the middle of nowhere," Wellerstein said. The laboratory, located in the remote mountains of northern New Mexico, was established in Los Alamos wasn't the only laboratory involved in the Manhattan Project.

The questions investigated by these university laboratories could easily be portrayed as relating to some other application of physics, and not necessarily bomb development, Wellerstein said. Los Alamos' remote location was crucial in keeping the purpose of the project a secret. Questions explored at Los Alamos included how to physically construct a bomb, how to design it, and where to put it together — "really practical, physical stuff," Wellerstein said.

To build a bomb, scientists needed large amounts of unstable, radioactive uranium or plutonium. Uranium was easier to obtain than plutonium but scientists thought that plutonium might provide a quicker route to developing the bomb, according to the Department of Energy.

They decided to try both and built nuclear reactors for each element — the Oak Ridge uranium reactor in eastern Tennessee and the Hanford plutonium reactor in Washington.

It took tens of thousands of people to build and operate these facilities: scientists, custodial staff, secretaries and administrative workers. By the end of the war, over , people had worked on the project, Wellerstein said. That the bomb was completed by the United States in time to help finish the conflict is remarkable. Most of the theoretical breakthroughs in nuclear physics that made it possible dated back less than twenty-five years, and, with new findings occurring faster than they could be absorbed by practitioners in the field, many fundamental concepts in nuclear physics and chemistry had yet to be confirmed by laboratory experimentation.

Nor was there any conception initially of the design and engineering difficulties that would be involved in translating what was known theoretically into working devices capable of releasing the enormous energy of the atomic nucleus in a predictable fashion.

The industrial base created in a handful of years to transform these theories into reality was, by , comparable in size to the American automobile industry.

Approximately , people were employed by the project at its peak, from laborers to Nobel Prize winners. The Manhattan Project was as much a triumph of engineering and industry as of science. Without the leadership of Leslie Groves and Robert Oppenheimer , as well as that of Crawford Greenewalt of DuPont and other contractors, the revolutionary breakthroughs in nuclear science achieved by Enrico Fermi , Niels Bohr, Ernest Lawrence , and their colleagues would not have produced the atomic bomb during World War II.

Despite numerous obstacles, the United States was able to combine the forces of science, government, academia, the military, and industry into an organization that took nuclear physics from the laboratory and on to the battlefield with a weapon of awesome destructive capability, making clear the importance of basic scientific research to national defense.

The Manhattan Project became the organizational model behind the remarkable achievements of American "big science" during the second half of the twentieth century. Atomic bombs have been used only twice in war—both times by the United States The explosion immediately killed an estimated 80, people; tens of thousands more would later die of radiation On August 5, , representatives of the United States, Soviet Union and Great Britain signed the Limited Nuclear Test Ban Treaty, which prohibited the testing of nuclear weapons in outer space, underwater or in the atmosphere.

The treaty, which President John F. Kennedy signed An arms race occurs when two or more countries increase the size and quality of military resources to gain military and political superiority over one another.
