· Trinity was the code name of the first detonation of a nuclear device. This test was conducted by the United States Army on July 16, 1945,[4][5][6][7] [8] in the Jornada del Muerto desert about 35 miles (56 km) southeast of Socorro, New Mexico, · Castle Bravo nuclear test, 1954 In 1954 the United States conducted Operation Castle, a series of nuclear tests in the Marshall Islands; the goal was to test prototypes of the first weaponized thermonuclear weapons · Tsar Bomba (Russian: -) is the nickname for the AN602 hydrogen bomb, the most powerful nuclear weapon ever detonated it was tested on October 30, 1961, in the Novaya Zemlya archipelago.[2][3] Kasutatud kirjandus: A.Ainsaar füüsika 12.klassile lk 29-31. http://et.wikipedia.org/wiki/Kriitiline_mass http://et.wikipedia.org/wiki/Tuumaenergia
make carbon. The new surge of energy keeps the core from collapsing much further. For an isolated star no heavier than the sun, there is little more to the story. The star burns all of its helium and shrivels. It turns into a white dwarf about the size of Earth, aging and cooling indefinitely--unless it lies close enough to another star to steal its neighbor's outer layers of hydrogen. If enough material falls onto the white dwarf, the siphoned fuel ignites a thermonuclear explosion. As the detonation spreads, the entire star blows up in what is known as a type 1a supernova--a giant nuclear bomb. The supernova blossoming over Palomar was a different kind: not a thermonuclear blast but a star's catastrophic collapse. This is the only kind of supernova that can unleash a gamma-ray burst, and it is the inevitable fate of a star more than eight times as massive as the sun. Such heavyweight stars always lose their battle with gravity. With the crushing weight of the
John von Neumann wrote "First Draft of a Report on the EDVAC." Grace Hopper recorded the first actual computer "bug." 1946 In February, the public got its first glimpse of the ENIAC, a machine built by John Mauchly and J. Presper Eckert that improved by 1,000 times on the speed of its contemporaries. Fully programmable (Turing complete) all-electronic computer Initial versions required rewiring to reprogram. Used for ballistic calculations for the military & for calculations for the thermonuclear bomb. START OF PROJECT: 1943 COMPLETED: 1946 PROGRAMMED: plug board and switches SPEED: 5,000 operations per second INPUT/OUTPUT: cards, lights, switches, plugs FLOOR SPACE: 1,000 square feet PROJECT LEADERS: John Mauchly and J. Presper Eckert. 1947 Three scientists at Bell Telephone Laboratories, William Shockley, Walter Brattain, and John Bardeen demonstrate their new invention of the point-contact transistor amplifier.
