Transcript of Manhattan Project Presentation

The Manhattan Project By: Nick Laing On August 9, 1945, three days after the bombing on Hiroshima, the, "Fat Man" atom bomb is dropped on Nagasaki
This atom bomb is made using plutonium
It explodes with the force of 20,000 tons of TNT
The imediate death toll was about 45,000 There were about 145,000 deaths from Hiroshima and Nagasaki
It took 2 billion dollars to complete the project(26 billion today)
On August 14, 1945, Japan surrendered
The United Nations established its atomic energy commission Pictures Process Originaly, the United States was going to drop the bomb on Germany
In April, 1945, the target comittee for the Manhattan Project changes their target from Germany to Japan,
This is mostly because of pearl habor, and Germany had become less of a threat.
More specifically, they were going to bomb Hiroshima and Nagasaki(two cities in Japan) On July 21, 1945, President Truman
approves the use of atomic bombs.
However, President Truman thought
that they should warn Japan before the bombings Albert Einstein's
Letter The Construction of the
Atomic Bomb At first, they did most of their work in New York
On November 25, 1942, Leslie R. Groves selects Los Alamos, New Mexico for the site in which the atom bomb would be created.
The First Pure sample of Plutonium is isolated
Enrico Fermi made the first controlled nuclear reaction. Causes of the Manhattan Project Results End of Construction Discoveries:
In 1900, P.V. Villard discovers gamma rays
In 1902, Ernest Rutherford discovers the atomic nucleus
Glenn T. Seaborg discovers plutonium
In May 1932, James Chadwick discovers the neutron
Leo Szilard conceives the idea of an atomic bomb. Warning Japan President Truman proposes the Potsdam Declaration to Japan
It was a document warning Japan to surrender.
Japan refuses to accept the declaration. Albert Einstein sent a letter to
Franklin D. Roosevelt warning
him that the Germans were making an atomic bomb(even though he wrote the letter, Enrico Fermi thought of the idea of warning the United States, after they fled from Germany).
It also pushed him to have the United States make their own atomic bomb
However, at first, FDR did not like the idea of making an atomic bomb.
FDR eventually had the first meeting of the Advisory Committee on Uranium
FDR approved the construction of the atomic bomb after the meeting. Leslie R. Groves Enrico Fermi Oakridge Oakridge was a town in Tennesee
It was created to produce oil, and other fuel sources for the project such as Uranium and Plutonium
This employed over 120,000 people
The United States Government wanted to keep the project confidential, so they did not tell the workers what they were making fuel for. In return, the workers got good pay, free food, decent homes, and little to no expenses
Some died on the job from over exposure to harmfull substances Oakridge President Truman Hiroshima On August 6, 1945, the, "Little Boy" atom bomb is dropped on Hiroshima, Japan from a plane called the, "Enola Gay"
This atom bomb was made using uranium
It explodes with the force of 13,000 tons of TNT
The death toll is an estimated 70,000 to 130,000 deaths The Little Boy bomb Nagasaki The Fat Man bomb Hiroshima and Nagasaki explosions Hiroshima in ruin after the explosion Nagasaki in ruin What is the Manhattan Project? The Manhattan Project was created to help put an end to World War II, and resulted in the fatalities and employment of hundreds of thousands of people, and the dropping of the famous atom bomb. It was called the Manhattan
Project because most of the early development of the atomic bomb took
place in New York
It was also known as, "Project Y".
The project was so confidential that not even the vice president knew about it. Albert Einstein Franklin D. Roosevelt 1945, "Enola Gay" Present Day, "Enola Gay" The Trinity Test It was the first testing
of the atomic bomb
It took place 20 miles from
Los Alamos, NM
They were running so
low on supplies that they used duct tape to strap up the bomb
The bomb was a success Thanks for listening.

How does it work? It is basically has two samples of reactive substances such as uranium and plutonium inside of the structure of the bomb and at top speeds, they colide causing the neutrons from one sample bombarding the nucleus of the other, causing the neutron to split, resulting in the loss of mass, resulting in the production of kinetic energy and thermo energy, and because the neutron keeps spliting and kinetic and thermo energy are still being made, it results in a massive explosion
