• Vannevar Bush, a scientist consultan of government, presides the mighty Carnegie Foundation and gather scientists, military and industrial sector. The first step to create the Military-Industrial Complex of United States.

The conclusion:

A big Uranium Bomb (20K) = 1800 Tn of TNT

• Roosevelt decides to give the green light to forward the atomic researches even when EEUU keeps an isolationist position.
• The American nuclear program undertakes in the best of secrecy without knowledge of the congress of EEUU.
• The nuke physics disappear of scientists publications, High Security Reasons.

1941

• December, the Japanese Imperial Army attacks Pearl Harbor. EEUU have reasons to participate in the WWII finally.
• Roosevelt can join to the allies against the powerful axis of Japan, Germany and Italy. War burns the Pacific and extend itself by the five continents.

1942

• The colonel Leslie Groves is recruited. The mission: forward the nuclear researches. Code Name: Manhattan Project.
• Plutonium appears like an alternative and optimal material for the nuclear fission.
• This investigations needs a great team of physics, engineers and scientists, Groves choose Robert oppenheimer, a young theoretical professor of Berkeley University, to leader such team.
• Upper Katanga Mining Union, a Belgian mining company, guarantee supplies all the uranium for the manhattan project.

• Summer, Germany abandon their nuclear program (Allies don't know). Petroleum is a primal target for their war.

• The first artificial nuclear reactor was built by the Manhattan Project's Metallurgical Laboratory at the University of Chicago, and was initiated in CP-1 on 2 December 1942, under the supervision of Enrico Fermi, who described the apparatus as "a crude pile of black bricks and wood".

• Hiroshima must be destroyed to consolidate the Economic and Political power of the American Military-Industrial Complex.
• Nagasaki would be bombed to contrast the destructive and production results between both formats of bombs: Uranium-235 and Plutonium.

• The Manhattan Project is spread throughout the US geography.

• Groves compartmentalize the various departments of manufacturing to the utmost to preserve absolute secrecy.
• Most employees will not know until the end of the war what they were actually working on.

• Los Alamos is the third big investigation center of the Manhattan Project.
• In this place converge all the materials produced in the other industrial plants, with this they could build the first atomic bombs.

Meanwhile:
• Two years after to share the MAUD inform, around twenty british investigators join to Manhattan Project in Los Alamos.
• The scientists live in a sort of family life into the installations, without exterior contact. The media age is 27 years old.

• The first victims of this project are the scientists. Radiation poisoning appears in the atomic vocabulary and no one knows how could affect the health.

• The globe division begins between the Allies and Soviets.
• Hiroshima must be destroyed to ensure the American advantage over the Soviets.

• Churchill realizes that Stalin claims Eastern Europe and calls Truman to meet.
• Truman expects to know the results of atomic testing before gather.
• EEUU prepares the future and the Bomb is the key to get this purpose. The prospect of a large-scale nuke industry begins to take shape.

Meanwhile:
• Alamo Gordo, July 16, 1945, all is ready to test the first Nuclear Bomb. Code name: Trinity.
• They call it "The Gadget" a implossion bomb filling with plutonium. 150,000 people worked giving life the monster.
• Results exceed expectations. Truman is informed inmediately, during the conference, about the succesfull test. America have now the absolute weapon, so they lead the talks. The Cold War Chapter One was writed.

August 6, 1945

• The legend: The launch of the two atomic bombs saves millions lives, so it is a necessary evil, ending the WWII.
• Actually, Hiroshima must be destroyed to show the militar powerful of EEUU.
• From the american militar airport of Tinian the B-29 superfortress called Enola Gay take off with the target to bomb Hiroshima. A similar operation is previewed for August 9, the next target is Nagasaki.

• Hiroshima: The bomb is dropped from 9,000 meters high it's explode 40 seconds later 600 meters over the city.
• The clocks stop at 08:15, the fire ball generated for the nuclear explosion reaches 1,000,000 degrees Celsius burning all the oxygen in its path.
• The explosion kills around 70,000 people, other 70,000 will die because the radiation effects. 200,000 people survive they are the "Hibakushas", the radiated by the atomic bomb.

• At the end of 1945 in New york scientists, industrials and military meet in a congress talking about the atom's future, and how to use the atomic energy with peaceful purposes.
• "Peaceful" this word ends the Hiroshima and Nagasaki chapter and open the path to create a civil nuclear industry. Nuclear energy conquer the world and becomes a industrial economic power.
• Progress is the "the leitmotif" without consult the people, and the paroxysm of the progress is the nuke energy.
