  • Albert Einstein - 766 words
    Albert Einstein When many people hear the name Albert Einstein, they say, Ooh what did he do, write a bunch of stuff on a chalkboard, prove to some scientists that he was right, and then star in a Pepsi commercial? Well, Im here to tell you that he did much more than that, (even though I really like that Pepsi commercial.) Albert Einstein was born March 14, 1879 in Ulm, Wrttemberg, Germany. Albert began his extensive studies at a school in Munich. At Munich he pursued a career in Electrical Engineering, but failed an exam and was rejected from Eidgenssische Technische Hochschule in Zurich. After failing at his original choice of schools, he went on to a secondary school in Aarau to train him ...

  • Atomic Bomb - 822 words
    Atomic Bomb Atomic Bomb On August 2, 1939 Albert Einstein wrote to President Franklin D. Roosevelt. This was right before the start of World War 2. In this letter Einstein and several other scientists told Roosevelt of the efforts Hitler was making to purify U-235 in which he hoped to make an atomic bomb. This is when the United States started the Manhattan Project. This was the project of making an atomic bomb. In the project many brilliant minds were used. The most famous of these people is Robert Oppenheimer. He was the major person behind this project. He basically ran the operation and oversaw the hole project from start to completion. Other great people like H.C. Urey, Ernest Lawrence, ...

    ... n in space. At this exact point in time, high amounts of radiation are given off, and with the proper equipment, can be detected and seen as an image of a black hole. Through this technique, astronomers now believe that they have found a black hole known as Centaurus A. The existence of a star apparently absorbing nothingness led astronomers to suggest and confirm the existence of another black hole, Cygnus X1. By emitting gravitational waves, non-stationary black holes lose energy, eventually becoming stationary and ceasing to radiate in this manner. In other words, they decay and become stationary black holes, namely holes that are perfectly spherical or whose rotation is perfectly uni ...

    ... or real, existing ones. The singularity in the this hole is more time-like, while the other is more space-like. With this subtle difference, objects would be able to enter the black whole from regions away from the equator of the event horizon and not be destroyed. The reason it is called a black hole is because any light inside of the singularity would be pulled back by the infinite gravity so that none of it could escape. As a result anything passing beyond the event horizon would dissappear from sight forever, thus making the black hole impossible for humans to see without using technologicalyl advanced instruments for measuring such things like radiation. The second part of the name ...

  • Hiroshema - 873 words
    Hiroshema Hiroshema War is an ever changing, advancing type of combat. From swords to guns, the weapons used are always developing and becoming much more powerful. Nuclear bombs are one of the most forceful weapons that exist today. On August 6, 1945, during World War II, the United States dropped an Atomic bomb on Hiroshima, a Japanese city and Military center. About 130,000 people were reported dead injured, or missing. Another 177,000 were left homeless. It was the first Atomic bomb ever used against an enemy. The effects of this explosion were so devastating and long lasting that they are still felt today. Was the United States justified in the dropping of the atomic bomb? On December 7, ...

    Hiroshima We have spent 2 billion dollars on the greatest scientific gamble in history - and won. - President Harry Truman Up until August 6th, occasional bombs, which did no great damage had fallen on Hiroshima. Many cities roundabout, one after another were destroyed, but Hiroshima itself remained protected. There were daily observations of planes over the city, but none of them dropped a bomb. The citizens wondered why they alone, had remained undisturbed for such long a time. There were fantastic rumors that the enemy had something special in mind for this city, but no one had dreamed that the end would come in such a fashion as on the morning of August 6th. Undoubtedly, the atomic bombi ...

  • Hydrogen Bomb - 821 words
    Hydrogen Bomb The Hydrogen Bomb The hydrogen bomb is a nuclear weapon in which light atomic nuclei of hydrogen are joined together in an uncontrolled nuclear fusion reaction to release huge amounts of energy. The hydrogen bomb is about a thousand time more powerful than the atomic bomb, which produces a nuclear fission explosion almost a million times more powerful than that of a comparably sized bomb using conventional high explosives such as TNT. The atomic bomb was an essential first step towards the development of the hydrogen bomb, before the atomic bomb w2as developed by the United States during World War 2, there was no way to produce the extreme amounts of heat needed to initiate the ...

  • Manhattan Project - 1,922 words
    Manhattan Project Manhattan Project In the early morning hours of July 16, 1945, the first ever nuclear explosion took place in Alamogordo, New Mexico. The explosion was the first test of the most destructive weapon ever known to man, and was the result of almost six years of research and development by some of the world's top scientists. This endeavor was known as the Manhattan Project. Less than a month after the test, which was known as Trinity, the United States dropped two nuclear bombs on Japan, three days apart, which forced the Japanese to surrender. The story of the Manhattan Project is an abysmal subject, as is the effect of the Manhattan Project on international politics, and both ...

  • Manhattan Project And The Abomb - 1,664 words
    Manhattan Project and the A-Bomb Just before the beginning of World War II, Albert Einstein wrote a letter to President Franklin D. Roosevelt. Urged by Hungarian-born physicists Leo Szilard, Eugene Wingner, and Edward Teller, Einstein told Roosevelt about Nazi German efforts to purify Uranium-235 which might be used to build an atomic bomb. Shortly after that the United States Government began work on the Manhattan Project. The Manhattan Project was the code name for the United States effort to develop the atomic bomb before the Germans did. "The first successful experiments in splitting a uranium atom had been carried out in the autumn of 1938 at the Kaiser Wilhelm Institute in Berlin"(Grou ...

  • Nuclear Arms - 622 words
    Nuclear Arms On August 6, 1945, Hiroshima was devastated by a most cruel and terrible new bomb, as described by Emperor Hirohito, one of the Axis leaders during World War II. Since then, nuclear weapons have become a major threat to humanity as more and more missiles, bombs, and other weapons are created by different countries. Today, many nations, including the United States and Russia, are working together to disarm their stockpile of nuclear weapons. Germany first started developing a fission bomb in 1939. Albert Einstein, along with other scientists, realized this and wrote to President Roosevelt regarding the threat to the Allies. Shortly after, the United States began serious efforts t ...

  • Nuclear Weapons, Explosive Devices, Designed To Release Nuclear Energy On A Large Scale, Used Primarily In Military Applicati - 1,937 words
    Nuclear Weapons, explosive devices, designed to release nuclear energy on a large scale, used primarily in military applications. The first atomic bomb (or A-bomb), which was tested on July 16, 1945, at Alamogordo, New Mexico, represented a completely new type of artificial explosive. All explosives prior to that time derived their power from the rapid burning or decomposition of some chemical compound. Such chemical processes release only the energy of the outermost electrons in the atom. See Atom and Atomic Theory. Nuclear explosives, on the other hand, involve energy sources within the core, or nucleus, of the atom. The A-bomb gained its power from the splitting, or fission, of all the at ...

  • Oppenheimer - 1,222 words
    Oppenheimer Dr. Julius Robert Oppenheimer Julius Robert Oppenheimer was an American physicist and government adviser, who directed the development of the first atomic bombs. To scientists, he was not only the builder of the atomic bomb and a pioneer in atomic energy, but a master of many languages, a good conversationalist and a brilliant mathematician. He was also a writer, and an expert in both the history of architecture and the religions of the world. Oppenheimer, who was born in New York City on April 22, 1904, and educated at Harvard University and the Universities of Cambridge and Gottingen, grew up in a middle class neighborhood. He was raised by his mother, who was an artist who pro ...

Over the course of ten days, Pasteur injected progressively more virulent rabies organisms into the boy, causing the boy to develop immunity in time to avert death from this disease. Another major milestone in the use of vaccination to prevent disease occurred with the efforts of two American physician-researchers. In 1954 Jonas Salk introduced an injectable vaccine containing an inactivated virus to counter the epidemic of poliomyelitis. Subsequently, Albert Sabin made great strides in the fight against this paralyzing disease by developing an oral vaccine containing a live weakened virus. Since the introduction of th ...

The first major challage the Manhattan project had was finding what fuel would be good for the atomic bomb. Neils Bohr said isotopes uranium-235 would be good because it was very unstable and can sustain the chain reaction. Glen Seaborg found out that you cloud also use plutonium-239. It is very hard to get them both. Second challenge was being able to get the uranium and plutonium to go through th fission chain reaction. Third challenge was getting the uranium or plutonium for the atomic bomb. They needed large amounts of that for the atom bomb. uranium-235 is taken f ...

    The Atomic Bomb The Atomic Bomb Albert Einstein predicted that mass could be converted into energy. This was the basis for the atomic bomb. Throughout this research paper, I will trace the history of the atomic bomb. In addition, who was involved and why, what happened in this event, and explain the impact that it had on the world. After Einstein predicted, that mass could be converted into energy. This was confirmed experimentally by John D. Cockcroft and Ernest Walton. "Physicists from 1939 onward conducted much research to find answers to questions as how many neutrons were emitted in each fission and which elements would not capture the neutrons but would moderate or reduce the velocity" ...

"At the moment of the explosion, a fireball was generated with a center, which reached a temperature of several million degrees Celsius. The heat rays released in all directions had a strong effect on the ground for about three seconds, starting approximately 1/100 second after the detonation. Due to the heat rays, the temperature in the hypocenter area is believed to have reached 3,000-4,000 Celsius Iron melts at 1,536 Celsius."

  • The Manhattan Project - 1,649 words
    The Manhattan Project In the months following the bombing of Pearl Harbor the Manhattan Project--the name given to the atomic bomb program because its original offices were in Manhattan--grew very quickly. And although the Army had been involved since June of 1942, it was just beginning to realize that someone was going to have to be put in overall charge. The man chosen was Leslie Richard Groves, a 46-year-old colonel in the Army Corps of Engineers. While he was a competent engineer, Groves was no scientist. He did not understand the science behind building the atomic bomb, nor did he pretend to. He needed someone who would be able to supervise the scientific side of the project. After dism ...

    The Manhattan Project The Manhattan Project The Manhattan Project was and is still one of the most secretive projects ever created in United States history. The purpose of the Manhattan Project was simple: to build; test; and unleash its power if necessary. Robert Oppenheimer and General Leslie Groves were the two men put in charge of this mission. These two men along with the top scientists from around the country were brought together to construct the most deadliest thing known to man. The project originated in the Pentagon in 1942 when General Groves was told, by the White House, he was to lead the Manhattan Project. World War II had already been raged for three years when the Nazis, afte ...

    The Manhattan Project On the morning of August 6, 1945, a B-29 bomber named Enola Gay flew over the industrial city of Hiroshima, Japan and dropped the first atomic bomb ever. The city went up in flames caused by the immense power equal to about 20,000 tons of TNT. The project was a success. They were an unprecedented assemblage of civilian, and military scientific brain powerbrilliant, intense, and young, the people that helped develop the bomb. Unknowingly they came to an isolated mountain setting, known as Los Alamos, New Mexico, to design and build the bomb that would end World War 2, but begin serious controversies concerning its sheer power and destruction.

  • The Rise Of The Usa As A Superpower - 799 words
    The Rise of the USA as a Superpower The Rise of the USA as a Superpower The development and use of nuclear power has led to the United States assuming a position as the true World Military Superpower. The Unites States was the leader in planning, building, testing and actually using the most powerful nuclear weapon known to man. This country also led the world in relatively safe production of nuclear power. The only other competitor to the United States, the Soviet Union, had poor leaders, induced a poor economy, and eventually led the country to lose the race for superpower. During World War II, the United States began the research and development of the atomic bomb. Code-named the Manhatta ...
