The First & Only-Atomic Bomb
The atomic bomb, also known as the atom bomb or fission bomb, a weapon whose explosive power originates from the fission of atomic nuclei, a reaction in which an atomic nucleus splits in two. When the nucleus of a heavy atom, such as the element uranium-235, which is what the atom bomb is made out of, is split, a certain amount of mass disappears and an equivalent amount of energy is released. This was expressed by the equation E=mc2 (energy = mass times the speed of light squared).This is the energy that powers an atom bomb. On a pound-for-pound basis, the U-235 in an atomic bomb can release on the order of one million times as much energy as TNT, a high explosive. The atomic bomb is the first nuclear powered bomb ever used. The atom bomb was created by people that worked in the Manhattan Project. The explosion generated Alpha, Beta, Gamma and neutron rays. Alpha and Beta rays were absorbed by the air and did not reach to the ground. Gamma and neutron rays were strong enough to reach the ground; thus it was these rays that affected people. Within 1/16 mile radius from the explosion center, most people died within a few hours (even in the case where they were not directly exposed to the heat or wind). Within a half mile radius, most people died within 30 days after the explosion. The people who entered the area within a half mile radius from the explosion center in the first 100 hours after the explosion were also affected by the remaining radiation on the ground. Fortunately it has not been observed that the long term effects of radiation affected A-bomb survivors nor that a radiation exposure caused genetic damages. The United States made Japan surrender due to the atomic bomb, which caused many deaths and destruction in Hiroshima and Nagasaki. The atomic bomb left Hiroshima and Nagasaki in ruins.
The Manhattan Project was the code name for the U.S. government's secret project that was established before World War II and culminated in the development of the atomic bomb.
In 1938 many people feared that Hitler would build an atomic bomb after word spread that German scientist had split the uranium atom (fission). However, one of Hitlers mistakes was his persecution of Jewish scientists. This persecution resulted in numerous scientists seeking asylum in the United States.
The U.S. decided to develop the atomic bomb based on the fear they had for the safety of the nation. In August 1939 nuclear physicists sent manuscripts to Albert Einstein in fear the Germany might use the new knowledge of fission on the uranium nucleus as way to construct weapons. In response, on August 2, 1939, Einstein sent a letter to President Roosevelt concerning the pressing matter to use uranium to create such weapons before Germany (Doc A-1). To support the development of the atomic bomb, President Roosevelt approved the production of the bomb following the receipt that the bomb is feasible on January 19, 1942. From this day to December of 1942, many laboratories and ...
As long as there is love, there will be hatred; as long as there is peace, there will be war, and as long as there is a positive side, there is a negative side. During the Second World War, the Nazis were very powerful. Due to the fear of the Nazis, Americans started a project called “The Manhattan Project" in order to build a very deadly weapon that could even blow cities apart. The allied powers were so concerned with Nazi domination, that they never considered the outcomes of creating an atomic bomb which are also positive and negative. The development of the atomic bomb boosted the level of understanding in terms of physics and chemistry of that particular time period.
Decisions are the hardest thing to do, especially considering how Harry Truman decided to drop the US Atomic bombs onto Okinawa and Iwo Jima. The role to end the war with Japan was in his hands, but it would require releasing the most horrendous weapon ever known. Although, there was some controversy over Truman’s decision. Some people say that it was unnecessary to use the Atomic bombs, such as the Federal Council of Churches and the Christian Faith. They stated that: “As American Christians, we are deeply penitent for the irresponsible use already made of the atomic bomb. We are agreed that, whatever be one’s judgment of the war in principle, the surprise bombings of Hiroshima and Nagasaki are morally indefensible. ("8 Primary Pros and Cons of Dropping the Atomic Bomb")” People also
Perhaps one of the most controversial topics that have ever existed is whether the U.S should have dropped the atomic bomb on Japan. To some people this is a matter of morals, while to others it is a matter of what was better politically, while some others say that it was better because it reduced the number of people that died. There is two views on the atomic bomb dropping, one side says it was the right thing to do while the other side says it was the wrong thing to do and it seems as if the American people are the only ones that are saying that it was the right thing to do. In countries like Russia, China, Japan etc. they teach in schools that it was the wrong thing to do, while here kids are taught that the use of the atomic bomb was justified.
One of the most controversial decisions that have been made, in the history of the United States, was Harry Truman’s decision to drop atomic bombs on the two Japanese cities of Hiroshima and Nagasaki. The ever so controversial topic of the dropping of the atomic bombs has successfully driven people insane. People feel strongly that this decision was atrocious and unnecessary, while others believe the polar opposite, that it was completely necessary. Some historians argue that the human cost to the Japanese population can never justify the use of such weapons. Other historians see it from an optimistic perspective, that it would not have been moral if atomic weapons had not been used to end the war as quickly as possible. President Harry S.
The Manhattan Project The Manhattan Project was a research project, that created the United States first nuclear weapon, and led to its creation of the nuclear department during World War II. M.A.U.D. / M.A.U.D. group was created in 1940. Also, M.A.U.D was the secret name given to the group and it came from a phrase in a message from Niel Bohr (Cohen). This group produced a report that said that producing a fission bomb was possible. James Chadwick, a new member of the British M.A.U.D group, later wrote that at that time he realized that a nuclear bomb was able to be built in his lifetime.
At 5:30 AM July 16th 1945, the nuclear age had started. The world’s first atomic bomb was detonated. On August 6th 1942 at 8:15 AM, an American B-29 bomber, the Enola Gay, dropped a perfected atomic bomb created by the Americans, over the city of Hiroshima hoping to end the war. Thousands of people died in the two cities in Japan. They were Hiroshima and Nagasaki “the Manhattan Project”. The research and development project that produced these atomic bombs during this time was known as “the Manhattan Project”.
Atomic Bomb in World War 2 During World War II the United States government launched a $2 billion project. This project, known as the Manhattan Project, was an effort to produce an atomic bomb. This project was taken on by a group atomic scientists from all over the world.
Atomic Bomb The use of the atomic bombs on Japan was necessary for the revenge of the Americans. These bombs took years to make due to a problematic equation. The impact of the bombs killed hundreds of thousands of people and the radiation is still killing people today. People today still wonder why the bombs were dropped. If these bombs weren’t dropped on the Japanese the history of the world would have been changed forever. The Atomic bomb took 6 years to develop (1939-1945) for scientists to work on a equation to make the U-235 into a bomb. The most complicated process in this was trying to produce enough uranium to sustain a chain reaction. The bombs used on the cities cost about $2 billion to develop, this also making the U.S. wanting to use them against Japan. “Hiroshima was a major military target and we have spent 2 billion dollars on the greatest scientific gamble in history- and won.” (3) The bomb dropped on Hiroshima weighted 4.5 tons and the bomb used on Nagasaki weighted 10 kilotons. On July 16, 1945, the first ever atomic bomb was tested in the Jamez Mountains in Northern New Mexico, code named “Gadget.” The single weapon ultimately dropped on Hiroshima, nicknamed “Little Boy,” produced the amount of approximately twenty- thousand tons of TNT, which is roughly seven times greater than all of the bombs dropped by all the allies on all of Germany in 1942. The first Japanese City bomb was Hiroshima on August 6, 1945. An American B-29 bomber, named Enola Gay, flown by the pilot Paul W. Tibbets, dropped the “Little Boy” uranium atomic bomb. Three days later a second bomb named ”Fat Boy,” made of plutonium was dropped on the Japanese city of Nagasaki. After being released, it took approximately one minute for Little Boy to reach the point of explosion, which was about 2,000 feet. The impact of the bombs on the cities and people was massive. Black rain containing large amounts of nuclear fallout fell as much as 30km from the original blast site. A mushroom cloud rose to twenty thousand feet in the air, and sixty percent of the city was destroyed. The shock wave and its reverse effect reached speeds close to those of the speed of sound. The wind generated by the bombs destroyed most of the houses and buildings within a 1.
In 1941, The United States began an atomic bomb program called the “Manhattan Project.” The main objective of the “Manhattan Project” was to research and build an atomic bomb before Germany could create and use one against the allied forces during World War II. German scientists had started a similar research program four years before the United States began so the scientists of the “Manhattan Project” felt a sense of urgency throughout their work (Wood “Men … Project”).
On August 6, 1945, the U.S. dropped the world’s first atomic bomb over Hiroshima. Three days later, a second bomb was dropped on Nagasaki. On August 15th, the Japan announced unconditional surrender in World War II. To this day historians still discuss why the U.S. decided to use the atomic bombs. Orthodox historians argue that the decision to drop the bombs was a military one designed purely to defeat the Japanese. Revisionist historians argue that the bombs were not needed to defeat Japan; the bombs were meant to shape the peace by intimidating the Soviets. After analyzing the documents in The Manhattan Project it has become clear that the U.S. used the bombs during WWII not only to defeat the Japanese, but also to intimidate the Soviet Union
The Manhattan Project was the code name for a science project conducted during World War II by the United States with the partial support of the United Kingdom and Canada. The ultimate goal of the project was the development of the first atomic bomb before Nazi Germany. The scientific research was directed by physicist Julius Robert Oppenheimer while security and military operations were carried out by General Leslie Richard Groves. The project was carried out in many research centers being the most important of them the Manhattan Engineer District located on the site now known as Los Alamos Manhattan Project was the code name for a science project conducted during World National Laboratory. The project brought together a wealth of scientific luminaries as Robert Oppenheimer, Niels Bohr, Enrico Fermi, Ernest Lawrence, etc. . . . Since, after experiments in Germany before the war, it was known that atomic fission was possible and that the Nazis were already working on its own nuclear program, several bright minds met. Many Jewish ex...
When looking at the aftermath of the atomic bomb in both Nagasaki and Hiroshima the devastation it caused is evident. The majority of the population in Japan could have never imagined such a catastrophic event. On August 6, 1945 and August 9, 1945 massive amounts of lives were changed forever when an atomic bomb fell from the sky and created an explosion as bright as the sun. These two bombs were the first and only accounts of nuclear warfare. (“Atomic Bomb is…”) The impact that the two bombs left on the cities of Japan was tremendous. The bombing of Nagasaki and Hiroshima devastated the country through structural damage, long term medical effects, expenses, and the massive loss of life.
2 Manhattan Project – Name given to the development and research of the atomic bomb in the U.S.
The atomic bomb is a powerful, explosive nuclear weapon. It is fueled by the fission of the nuclei of specific amounts of plutonium or uranium, in a chain reaction. The strength of the explosion created by one of these bombs is equal to the strength of an explosion created by thousands of tons of TNT.
