Korean war


The korean war was a war that was not nessasery in my oponion. i was one the south koreans side in this war because i agree that capitilizm is better then the north koreans communism. north korea had been killing the south koreans for a while and south koreans only got the glory every once in a while but north korea was beaten them so bad at one point that the capitilists were brought back all the way to one city in the whole south korea. The city that they had to fight back out of was called pusan. north korea was helped and servised by china because they were communists to and didnt want america to win.the 38th parralell was the line that split the to nations apart.

h-bomb


The Teller–Ulam design is the nuclear weapon design concept used in most of the world's nuclear weapons. Colloquially referred to as "the secret of the hydrogen bomb," because it employs hydrogen fusion to generate neutrons, in most applications the bulk of its destructive energy comes from uranium fission, not hydrogen fusion. It is named for its two chief contributors, Hungarian-born physicist Edward Teller and Polish-born mathematician StanisÅ‚aw Ulam, who developed it in 1951, for use by the United States. It was first used in multi-megaton-range thermonuclear weapons. However, it is also the most efficient design concept for small nuclear weapons, and today virtually all the nuclear weapons deployed by the five major nuclear-armed nations use the Teller–Ulam design.
Its essential features, which officially remained secret for nearly three decades, are: 1) separation of stages into a triggering "primary" explosive and a much more powerful "secondary" explosive) compression of the secondary by x-rays coming from nuclear fission in the primary, a process called the "radiation implosion" of the secondary, and 3) heating of the secondary, after cold compression, by a second fission explosion inside the secondary.
The radiation implosion mechanism is a heat engine exploiting the temperature difference between the hot radiation channel, surrounding the secondary, and the relatively cool interior of the secondary. This temperature difference is briefly maintained by a massive heat barrier called the "pusher." The pusher is also an implosion tamper, increasing and prolonging the compression of the secondary, and, if made of uranium, which it usually is, it undergoes fission by capturing the neutrons produced by fusion. In most Teller–Ulam weapons, fission of the pusher dominates the explosion and produces radioactive fission product fallout.
The first test of this principle was the "Ivy Mike" nuclear test in 1952, conducted by the United States. In the Soviet Union, the design was known as Andrei Sakharov's "Third Idea," first tested in 1955. Similar devices were developed by the United Kingdom, China, and France, though no specific code names are known for their designs.

THE SPACE RACE


The Space Race was a heated competition between the United States and the Soviet Union in the exploration of outer space. It involved pioneering efforts to launch artificial satellites, send man into space, and land him on the Moon.
The Space Race occurred during the Cold War and had its origins in the missile-based arms race between the two nations. It effectively began with the Soviet launch of Sputnik 1 on 4 October 1957, and ended in a period of detente with the co-operative Apollo-Soyuz Test Project flight in July 1975. In between, it became a focus of the cultural, technological, and ideological rivalry between the two nations. It provided the side benefits of societal morale boosting, and civilian and military applications of the developed space technology. Rockets have interested scientists and amateurs for centuries. The Chinese used them as weapons beginning in the Song Dynasty, and simple (but inaccurate) iron rockets were common ship-and land-based weapons by the 19th century.
Russian pioneer Konstantin Tsiolkovsky theorized in the 1880s on multi-stage, liquid fuel rockets which might reach space and established the basics of rocket science. His rocket equation which determines flight velocity based on propellant consumption, is still used in the design of modern rockets today. Tsiolkovsky also wrote the first theoretical description of a man-made satellite.
Shortly after the fall of 1914, American Robert H. Goddard wrote a thesis, A Method of Reaching Extreme Altitudes after receiving two patents on elements of rocket propulsion. The paper was published by the Smithsonian Institution and gained him a $5,000 research grant, but unfortunately resulted in negative publicity for Goddard, ignoring his careful research and characterizing him as the "crackpot moon man." By 1926, he had built rockets and started outdoor testing, launching the first known liquid-fueled rocket. By 1929, he had attracted the attention of Mrs. Harry Guggenheim and Charles Lindberg. This resulted in another research grant of $100,000 from the Guggenheim Foundation, which allowed him to move to Roswell, NM to work on bigger and more complex designs. While his first design was uncontrolled, he later invented gyro-stabilized systems that foreshadowed those used in later practical space vehicles.
However, the realization of such vehicles required large amounts of capital, labor and material. Private enterprise would only undertake this given a profitable market, and as most of the public still scoffed at the idea of real-world space travel, this did not exist. Therefore, this implied the necessity of government sponsorship.

u-2 incidents


The 1960 U-2 incident occurred during the Cold War on May 1, 1960, during the presidency of Dwight D. Eisenhower, when an American U-2 spy plane was shot down over the Soviet Union. The United States government at first denied the plane's purpose and mission, but then was forced to admit its role as a covert surveillance aircraft when the Soviet government produced its remains (largely intact) and surviving pilot, Francis Gary Powers. Coming just over two weeks before the scheduled opening of an East–West summit in Paris, the incident was a great embarrassment to the United States and prompted a marked deterioration in its relations with the Soviet Union.

the arms race

In the historical period preceding World War I, Germany, Russia, United Kingdom, France, and Austria-Hungary all strived to build up their respective armies. The theory behind this buildup was to deter other nations from an attack by threatening many more losses than would be worth the potential gains from a war. This strategy served to increase tensions in Europe and led to the formation of alliances and the utilization of defensive stategy. Many theorists cite the beginning of World War I as a direct result of the military buildup by many European nations.At the geopolitical level of the 20th century, the United States and the Soviet Union developed more and better nuclear weapons during the Cold War . Immediately after World War II, the United States was behind the Soviet Union in the area of intermediate range missiles, but they managed to catch up with the help of German scientists. The Soviet Union committed their command economy to the arms race and, with the deployment of the SS-18 in the late 1970s, achieved first strike parity. At the peak of the arms race in the late 60s and early 70s both the United States and the Soviet union were spending $70-80 billion each on nuclear weapons. The United States had the ability to spend money more easily than the Soviet Union because it did not suffer the destruction during the war that the Soviet Union did. The Soviet Union did not have the ability to sustain the arms race with the United States because in doing so it was depriving its citizens of basic consumer goods. The strain of competition against the great spending power of the United States created enormous economic problems during Mikhail Gorbachev's attempt at konversiya, the transition to a consumer based mixed economy and hastened the collapse of the Soviet Union. Because the two powers were competing with each other instead of aiming for a predefined goal, both nations soon acquired a huge capacity for overkill.

the super powers


The cold war was a big thing.on my opinion i would go for the USA on this one but I'm only doing that because i live there if i didn't i prob go with u.s.s.r because the soviet union is just a big country that have allot of power and nukes at there disposal. the whole main thing about the cold war was that the u.s.s.r wanted to show everyone that Communists are good and to show that Communism was the right way to go in there country to be is big and glorious as they are. but the USA was not to happy about them having so much power and so much resources and that they were communists. so USA put into action that they want to show people how to be capitalists.so the Truman started or made the Truman doctrine. the doctrine was that if any capitalist country's need help from communism that the USA would help and aid.so for the super powers i am going to have to go with the united states of America.
