The History Of Nuclear Fission

In August 1945, America dropped two Atomic bombs on Japan in the cities of Hiroshima and Nagasaki. The two bombings killed at least 130,000 people and were the first and last use of nuclear weapons in warfare.

World War 2 was one of the worst wars in world history. The allied forces, the U.S., France, China, Russia, and Great Britain, were at war against the axis powers, Germany, Italy, and Japan, to stop the nazis from taking over the world. There were many bad events and battles that happened over the 6 year time span of the war; but one of the worst has to be the Hiroshima and Nagasaki bombings at the end of the war. Some people say that the U.S. Needed to drop the bombs to save American and Japanese lives. Some think otherwise, that the bombs were not nessecary to end the war. Even the scientists who created the bombs believed it shouldn't have been used. Once the bomb was created, there was controversy

The atomic bomb was seen as a weapon capable of ending the war, and it did just that. Due to its quick and magnificent destruction capabilities, the United States could avoid hand to hand combat and save the lives of many Americans. On the other hand, the bombs were seen as unnecessarily brutal. Because of its lethal range, hundreds of thousands of civilians were killed.

The Atomic Bomb or known Atom Bomb was created by a scientist, which assembled the first bomb. He and General Leslie Graves officially and successfully tested it in New Mexico, July 21, 1945. Despite this, two refugees from Italy and Germany in the early 1940’s, Enrico Fermi and Leo Szilard were the first to ever produce a controlled chain reaction. The bomb was created to use during WW2 and end it. This was big for America as president Franklin was notified that Germany was working on a similar weapon to use on America and its Allies. This bomb was needed to win the war and it took approximately 160,000 lives as a result while also having many affects on the people then, the people today, and the environment (Henretta, Edwards, & Self, 2012). The US was the first and only country to this day to drop an atomic bomb on another country, not once, but twice. This did end the war; however, the results were quite devastating to Japan. The environment and lives lost were all greatly impacted however, the world as a whole would be impacted for years to come. It also had its political reasoning behind it to show the global power of America. The devastation caused by the bombs also created deterrence from using them in the future at the time. Furthermore, now as other countries have improved technological

During World War II, there was much advancement in technology that led to the destruction of many countries after World War II. New advanced weaponry of World War II or “The Great War” led a lack of new skills that led to many casualties because of the advancement in technology. The most significant weapon that was used and had a huge impact in the World War II was the creation of the atomic bomb. This weapon was so significant because as soon as this weapon was dropped, it would immediately cause great destruction from its explosion. The United States was the first to create and use the atomic bomb. In July 1945, the Manhattan Project, which was the creation of the atomic bomb, was successfully tested the first atomic bomb in New

World War II began September 1, 1939 and ended September 2, 1945. When this war began, many young boys and men were drafted into the war. Most of them left what they were doing and all they’ve known, to fight in the war. It was the war that advanced technology and created social changes. The United States was the first country to use the atomic bomb in warfare. On August 6, 1945, the first of two atomic bombs were dropped. The first bomb was named, “Little Boy,” and was dropped on the city of Hiroshima. The second bomb was named, “Fat Man,” (History.com Staff 2009) and was dropped on the city of Nagasaki three days later. The bombs resulted in thousands of casualties and radiation among the civilians. Dropping the atomic bomb was the right decision because the bomb would end the war, it was revenge for Pearl Harbor, and it saved the lives of more Americans.

On 06 August 1945, the United States denoted a nuclear weapon over the Japanese city, Hiroshima due to the major military headquarters the housed. The event took place during the final stage of World War II, it is uncertain to the amount of people harmed in this event, to this day, with the long-lasting effects of the bombing survivors are still taking ill.

The atomic bomb was dropped on Hiroshima on August 6, 1945. The bomb was used to end the war 6 months earlier than the war would have ended naturally. If the bomb was never dropped then the United States would have invaded japan and lost up to 1,000,000 soldiers in the battle (source 8). The United States should not have dropped the bomb because it killed more innocent people than it did threats to the country. The bomb had a blast radius of over 2,000 yards. This bomb disintegrated anything that was 1 mile within ground zero which was the drop site of the bomb.

The atomic bomb was one of the most impacting event of the 20th century. It forever changed the way that people looked at war. For the first time, the human race possed the ability to destroy on a massive scale, and they actually got to see how they could do it during the second World War. It was a decision that the president, Harry Truman, had to think and decide very carefully on what exactly he wanted to do. Never in the history of war has anyone had the power that now existed within the United States of America. With a single decision, the President struck fear in the people of other nations. It was an exclamation point that stated how powerful a nation that America now is.

Two of the most destructive bombs were dropped on August 6 and August 9, 1945. The bombs “Fat Man and Little Boy” were dropped on the cities of Nagasaki and Hiroshima killing thousands. It did however end one of the most devastating wars in history, World War 2. In 1940 the U.S government authorized the research of nuclear weapons. It began funding a top secret program named “The Manhattan Project.”

The United states making the atomic bomb was done at University of Chicago in 1942. The U.S.A. used the bombs to make japan surrender, also because japan fought to the death and it almost like a last result for us. The bombs were dropped at the city of Hiroshima, japan and Nagasaki, Japan. The day they were dropped was on August 6, 1945 on the two cities. As a result of the bomb at Hiroshima between 80,000 and 120.000 people died. At the other city of Nagasaki 30,000 and 75,000 people died. Later, there were tons of cases of cancer deaths from the radiation from the two bombs. Even the pilot that dropped the bomb said, "what have we done."  Even Albert Einstein later said, "I wish I never suggested it." But, in the end Japan

The Atomic Bomb was created and used to help end WWII. Many countries came together to help design and make the bomb. More than 130,000 scientists put their lives and their families lives at risk by making these bombs. After the bombs were made and the hard decision to drop them ended, the atomic bomb changed the future forever. Nuclear weapons even made the rules of war change to save mankind and this planet.

Fission is another way for saying splitting. Splitting a nucleus is called nuclear fission. Uranium or plutonium isotopes are commonly used in nuclear reactors, because their atoms have relatively large nuclei that are fairly easier to slip, especially when collided with neutrons. When a uranium-235 or plutonium-239 nucleus is hit by a neutron, the following happens:

In August of 1945, both of the only two nuclear bombs ever used in warfare were dropped on the Japanese cities of Nagasaki and Hiroshima. These two bombs shaped much of the world today.

The atomic bomb has spread fear, terror, and uncertainty of the future around the world. Immediately after the first bomb went off, the Japanese were scared and confused as to what had just happened to their city. When just days later another bomb was dropped, it caused a tremendous amount of panic for them. As the word was spread throughout the world, it caused more and more talk of where else this could potentially happen. People no longer felt safe where they were but they couldn’t do anything about it. Even today the threat of another atomic bomb is lurking around all of us, and the idea of it is quite terrifying. For something as destructive as the atomic bomb you have to wonder, what if a military were to use this type of weaponry
