Atomic Timeline

      Atomic Timeline - Definition
This timeline relates to the events leading to the development of nuclear weapons which derive destructive energy from the release of atomic energy in nuclear weapons and atomic bombs. At the beginning of the 20th century scientists realized the atom could be split and the atom's elementary building blocks the electron, proton, and neutron were mapped which led to the discovery of nuclear fission transforming the atom into a new and powerful source of energy.
 
         
    1704 Isaac Newton: modelled the atom using billiard balls  
         
    1789 Martin Heinrich Klaproth discovered Uranium.  
         
    1862 Mechanical submarine invented by  NarcĂ­s Monturiol i Estarriol  
         
    1866 Dynamite invented by  Alfred Nobel  
         
    1869 Mendeleev produces the Periodic Table  
         
    1873 James Clerk Maxwell: introduced the electro magnetic field around atoms  
         
    1885 The Balmer series - light was shot through hydrogen and the light spectrum that came from it was studied  
         
    1887 Heinrich Hertz: discovered radio (electric waves)  
         
    1895 Roentgen discovers X-rays. Cloud chamber for tracking charged particles is invented  
         
    1896 Henry Becquerel: finds radioactivity  
         
    1897 J.J. Thompson: discovered electrons using cathode rays, showed that glowing matter wasn't light waves  
         
    1898 Pierre and Marie Curie discover the first radioactive elements: radium and polonium  
         
    1899 E. Rutherford: publishes discoveries on radiation, including alpha and beta particles  
         
    1900 Planck develops quantum theory  
         
    1903 Rutherford and Soddy work on spontaneous decay and radioactivity, half lives and the amount of energy released  
         
    1905 Albert Einstein introduces his special theory of relativity and the mathematical formula E=mc2, or energy equals mass multiplied by the speed of light squared, which demonstrates that mass can be converted into energy  
         
    1911 George von Hevesy conceives the idea of using radioactive tracers  
         
    1913 Niels Bohr introduced the first atom model, the mini solar system  
         
    1926 Robert Goddard experiments with liquid-fueled rockets.  
         
    1932 The Neutron is discovered. James Chadwick exposes the metal beryllium to alpha particles and discovers the neutron

Ernest O. Lawrence and M. Stanley Livingston publish the first article on "the production of high speed light ions without the use of high voltages."
 
         
    1934 Irene and Frederic Joliot-Curie discover artificial radioactivity  
         
    1937 5-million-volt Van de Graaff generator built and used as a particle accelerator in atom smashing

Alan Turing develops the concept of a theoretical computing machine
 
         
    1938 German scientists, Otto Hahn and Fritz Strassman, demonstrate nuclear fission  
         
    1939 1939 Atomic Timeline - September - WW2 starts September 1, 1939

1939-1945 Manhattan Project. The top-secret atomic energy program, known as the Manhattan Project, employed scientists under the direction of J. Robert Oppenheimer to develop the first transportable atomic bomb and produce the plutonium and uranium-235 necessary for nuclear fission
 
         
    1942 December 2, 1942, Enrico Fermi achieves a controlled nuclear chain reaction with a demonstration reactor, called the Chicago Pile 1  
         
    1945

Atomic Timeline August - 1945

  • August 9: The United States drops atomic bomb on Nagasaki in Japan (US Superfortress 'Bockscar' bomb was called Fat -Man) The 22 kiloton 'Fat Man' bomb killed 70,000 people)
 
         
    1954 Atomic Energy Act of 1954 - The U.S. Congress passed the Atomic Energy Act of 1954 allowing the Atomic Energy Commission to license private companies to use nuclear materials and build nuclear power plants

First nuclear power plant begins operation in the Obninsk Scientific Center, Russia
 
         
    1955 The USS Nautilus SSN 571 - the first nuclear-powered submarine  
         
    1957 The United States sets off first underground nuclear test in a mountain tunnel in the desert 100 miles from Las Vegas

Radiation is released when the graphite core of the Windscale nuclear reactor in England catches fire

The first U.S. large-scale nuclear power plant begins operating in Shippingport, Pennsylvania
 
         
    1965 The first nuclear reactor is operated from outer space  
         
    1979 Three Mile Island incident resulted in a partial meltdown of the core but only a minor release of radioactive material into the atmosphere  
         
    1986 Chernobyl - The Chernobyl nuclear disaster exposed millions of people to radioactive isotopes
