World war II Code name for

construction of the atomic bomb.

Involved nearly 125,000 people

Cost two billion dollars

Consisted of three Nuclear explosions The trinity test( 1 bomb

tested AKA Gadget) Hiroshima( 2nd

detonated August 6th 1945

Nagasaki( 3rd detonated Fat Man)▪ August 9th 1945▪ Ended World War II

In New Mexico

First nuclear explosive

Similar to the fat man Just a test Set off at Trinity July 16th 1945 More powerful than

expected 20,000 tons of TNT

Monday August 6th, 1945 City had large depots of

military supplies Nearly all civilians died Uranium based explosion

(Nuclear Fission) Killed nearly 90-166,000

people in first two months

Enola Gay Uranium

3rd detonated Ended WWII 1st two months, killed

nearly 60-80,000 people

Half died first day Flying Fortress Plutonium

This top secret project was conducted throughout the U.S. in many different states

Main test site was in New Mexico

Where the trinity test( 1st atomic bomb of

successfully detonatedManhattan is where most

early research was done

Although many renowned scientists were a part of this project many had second thoughts

Would it work What would the

devastation be Side effects?

Lasted about four years from the start to end of world war II One reason why people

were concerned to create an atomic bomb or not .

At beginning of war Albert Einstein wrote a letter to the president informing him that Germany was plotting the use of an atomic bomb, and urged him to do the same

•Moved to England and developed the of a nuclear chain reaction

Was convinced that the United States had

to study fission. Signed letter to FDR about nuclear weapons

Wasn’t completely for the use of nuclear weapons

With the help of LeoSzilard, Einsteinconvinced PresidentRoosevelt that Germanymay be using uranium

to create a super bomb.

Einstein helped the United States to beginthe same type ofresearch of uranium and fission that was

happening in Germany

Included Fusion Fission Chain reaction

Fusion is where the nuclei combine to form a large nucleus( atoms fuse together)

Like all other nuclear reactions this gives off enormous amounts of energy

Where a neutron causes the nucleus of an atom to split and become two separate ones.

Occurs when the neutrons that are released during fission cause others to split and release more neutrons

Repeated over and over

Domino Effect

Really fast( Millionth of a second

Gamma radiation give off which is the most deadliest known to man.

Enrico Fermi Richard Feynman Niels Bohr

J Robert Oppenheimer Leslie groves FDR Ernest Lawrence

Created the first controlled chain reaction in his lab.

Dealt with the math and equations that had to do with the atomic bomb

Theorized that U235 was most stable element that could go through a chain reaction

Stated a theory that if a neutron hit the nucleus of an atom fission would occur

Often referred to as father of the atomic bomb.

In 1943, was named the director for the Manhattan project

General, and was the military manager for the Manhattan project

Known as atomic Smasher

In charge of electromagnetic separation at Oak ridge

Which is where the Uranium 235 was produced for the bomb

President during World War II

Gave first thought to the atomic bome

But died before Nagasaki and Hiroshima and Harry Truman set the orders

Was it better to drop the bombs or just Threaten

Are the side effects worth the win

Would they work Would we have

enough time Where would we test Could we be exposed

to radiation

Who has them? Will they be used Will another war

happen????
