  • America's post-World War II period is often portrayed as a time of affluence and contentment, but fear of atomic war and Communist infiltration also marked the era and affected the decisions Americans made about their lives and futures. Fear of atomic bomb attacks on the nation's cities helped motivate people to move to the relative safety of the suburbs. Some Americans built fallout shelters to protect their families while others, shocked by the prospect of nuclear annihilation at any moment, sought to live for the present.
  • Once the first atomic bomb was dropped on Japan, Americans realized a new era in history, one defined by the ability of humans to destroy their world.
  • Positive portrayals of atomic bomb blasts, along with toys and games that made light of atomic bomb destruction like those in the case below, may have helped diffuse some of the fear the American public felt about the bomb by desensitizing them to the devastation an atomic bomb could cause.

  • While "atomic fiction" depicted possible fearful scenarios using atomic bombs and radiation, documentary sources illustrated the reality. Newspapers, magazines, books, and pamphlets described in vivid detail the effects of nuclear bombs on the Bikini Atoll, Hiroshima, and Nagasaki, kept Americans abreast of the latest atomic developments and their destructive forces, and explained the devastating results if a bomb were to be dropped on the United States. All combined to reinforce the fear Americans had about anything atomic
  • Atomic Age fears provided science fiction writers with the inspiration for hundreds of stories, many of which conveyed political and moral messages as they shocked and entertained American readers and movie audiences. Three story types had emerged by the mid-1950s: the first dealt with atomic warfare; the second showed dinosaurs or fantastical beasts awakened or created by atomic blasts; and the third type depicted human deformities resulting from atomic experiments gone awry.

    If you check out the times of atomic bomb progress, you will find that it only took 50 years since X-rays were discovered. pretty fast if you ask me

  • By the late 1950s, officials of the Eisenhower administration, after having seen the results of numerous atomic bomb tests, had a fairly realistic idea of how difficult it would be to survive a nuclear bomb blast. They continued, however, to disseminate somewhat dubious survival information, primarily to give the American public a sense of hope and control over their own lives. They also believed that a public confident of surviving an atomic war would support the federal government's decision to increase its own atomic arsenal, even though its existence could provoke a nuclear war with the Soviet Union.

  • The Manhattan Project was the code name for the U.S. effort during World War II to produce the atomic bomb. The program was under the leadership of Gen. Leslie Groves, and theoretical physicist J. Robert Oppenheimer. The main laboratory was built on an isolated mesa at Los Alamos, New Mexico. The first atomic bomb was tested at Alamogordo, New Mexico, on July 16, 1945.

  • As in many other first along the road of technological progress, the stimulus which initiated and sustained the effort that produced the ENIAC (electronic numerical integrator and computer)--the world's first electronic digital computer--was provided by the extraordinary demand of war
  • This Department had the responsibility for the design, development, procurement, storage, and issue of all combat materiel and munitions for the Army. In 1939 it was staffed by a relative handful of officers and career civilian employees.
  • One of the extraordinarily important tasks

  • was the preparation of firing and bombing tables for the Army which at that time, of course, included the Army Air Corps.
  • The analyzer installed at Aberdeen had ten integrating units and provisions for two input and two output tables as well. But, despite its value as an important mechanical aid to computation, it had several severe limitations.
  • It was, of course, known that the Moore School of Electrical Engineering of the University of Pennsylvania had a Bush differential analyzer of somewhat larger capacity than the one installed at Aberdeen. As a matter of fact, the one at the Moore School had fourteen integrating units. Therefore one of the first steps taken was the award to the University of Pennsylvania of a contract by the Ordnance Department for the utilization of this device.
  • he original agreement between the United States of America and the trustees of the University of Pennsylvania, dated June 5, 1943, called for six months of "research and development of an electronic numerical integrator and computer and delivery of a report thereon." This initial contract committed $61,700 in U.S. Army Ordnance funds
  • The ENIAC was placed in operation at the Moore School, component by component, beginning with the cycling unit and an accumulator in June 1944. This was followed in rapid succession by the initiating unit and function tables in September 1945 and the divider and square-root unit in October 1945. Final assembly took place during the fall of 1945. By today's standards for electronic computers the ENIAC was a grotesque monster. Its thirty separate units, plus power supply and forced-air cooling, weighed over thirty tons. Its 19,000 vacuum tubes, 1,500 relays, and hundreds of thousands of resistors, capacitors, and inductors consumed almost 200 kilowatts of electrical power. But ENIAC was the prototype from which most other modern computers evolved. It embodied almost all the components and concepts of today's high- speed, electronic digital computers. Its designers conceived what has now become standard circuitry such as the gate (logical "and" element), buffer (logical "or" element) and used a modified Eccles-Jordan flip-flop as a logical, high-speed storage-and-control device.
  • The ENIAC was not originally designed as an internally programmed computer. The program was set up manually by varying switches and cable connections. However, means for altering the program and repeating its iterative steps were built into the master programmer
  • The ENIAC led the computer field during the period 1949 through 1952 when it served as the main computation workhorse for the solution of the scientific problems of the Nation. It surpassed all other existing computers put together whenever it came to problems involving a large number of arithmetic operations. It was the major instrument for the computation of all ballistic tables for the U.S. Army and Air Force.

  • Today, the world is attempting to control nuclear proliferation through diplomacy and treaties. In 1996, the Comprehensive Test Ban Treaty prohibited nations from using bombs for either military or research purposes. Forty-one states with nuclear capabilities have signed the treaty, but it cannot take effect until three more nations join. India, Pakistan, and North Korea are among the countries that have refused. Although the United States has signed the treaty, it has not ratified it yet.
