FAQ

As Bohr explains, he knew Oppenheimer didn't need his help. Also, he didn't want to take part in creating the weapon that would "give them the power to destroy themselves.".

In their actual conversation, Truman stated: "I don't want to see that son of a bitch in this office ever again". He would later go on to call him a crybaby in a letter to Dean Acheson.

Thousands of black women and men contributed to the Manhattan Project, but not valuable enough to mention in a movie due to the nature of their labor. They were an important part of the workforce, especially at Hanford and Oak Ridge. More than fifteen thousand blacks arrived in the Tri-Cities during the Manhattan Project. Approximately seven thousand blacks worked in Oak Ridge for the Manhattan Project. Most, but not all, were lower-level laborers. They came to Hanford and Oak Ridge to help with the war effort and to earn higher wages but faced Jim Crow racism and segregation that was common throughout the United States at that time. Although black people were generally construction workers, laborers, janitors or domestic workers, a limited number of black women and men worked as scientists and technicians at smaller Manhattan Project sites in New York and Chicago.

This is a quote from the sacred Hindu text Bhagavad-gita chapter 11 verse 32 that originally reads "kalo'smi loka-ksaya-krt pravrddho"

Which translates more accurately to english as "Time; I am; the source of destruction of the worlds;

In the book context it means...

Everything eventually succumbs to time. The property of time on matter is that it ages it. With age comes the eventual breakdown of whatever has been assembled. The ingredients will remain but the form that they take will be broken.

3 weeks. The Trinity test was July 16, 1945. The bombing of Hiroshima was August 6, 1945 and Nagasaki 3 days later. However bear in mind that there were two types of bombs. A rifle type Uranium bomb was dropped on Hiroshima and a Plutonium implosion type on Nagasaki. The Trinity bomb was of the Nagasaki type.

The sunglasses were for the initial flash from the detonation, which can blind a person. They were able to turn and look at the explosion once the initial flash had dissipated.

The project involved several locations and facilities across the United States, Canada, and other countries. According to different sources, the number of locations and facilities varies, but some of the most prominent ones are:

• Columbia University in New York City, where the project's name was derived from and where much of the early research on uranium enrichment and nuclear physics was done.

• Oak Ridge in Tennessee, where three large plants were built to produce enriched uranium using various methods, such as electromagnetic separation, gaseous diffusion, and thermal diffusion.

• Hanford in Washington, where the world's first full-scale nuclear reactors were constructed to produce plutonium, a key ingredient for the implosion-type bomb.

• Los Alamos in New Mexico, where the design and assembly of the atomic bombs took place, as well as the testing of the first bomb at the nearby Trinity site.

• University of Chicago in Illinois, where the first controlled nuclear chain reaction was achieved under the leadership of Enrico Fermi at the Metallurgical Laboratory.

• Chalk River in Ontario, Canada, where a heavy water nuclear reactor was built to produce plutonium as part of the British-Canadian contribution to the project.

• Wendover in Utah, where the 509th Composite Group, the military unit that delivered the atomic bombs, trained and practiced with dummy bombs.

Other locations and facilities that were involved in the Manhattan Project include research laboratories, universities, factories, mines, and military bases in various states and countries, such as California, Iowa, Massachusetts, Michigan, Missouri, New Mexico, Ohio, Pennsylvania, Tennessee, Texas, Virginia, Colorado, New Jersey, New York, Oregon, Washington, D.C., Canada, England, and Norway. Some of these sites were used for developing and testing components, materials, and equipment for the atomic bombs, while others were used for procuring and transporting raw materials, such as uranium ore.

The exact number of locations and facilities that participated in the Manhattan Project is difficult to determine, as some of them were classified, temporary, or peripheral to the main activities of the project. However, one estimate suggests that there were about 30 major sites and 300 smaller ones that were directly or indirectly involved in the project. Another estimate puts the number of sites at more than 100.

He was an expert in determining effective blast radius dimensions.

There's conflicting numbers because it isn't certain how many people were actually killed. There was approximately 129,000-226,000 combined total killed in the bombings. Half killed in the initial blast and the rest dying of burns, radiation sickness, wounds and cancer.

Yes - "David L. Hill was an associate experimental physicist at the University of Chicago's Metallurgical Laboratory ("Met Lab") during the Manhattan Project." - Atomic Heritage Foundation

Harry K. Daghlian Jr. and Louis Slotin were two individuals who suffered from radiation exposure during separate criticality accidents involving nuclear experiments in the Manhattan Project.

Harry K. Daghlian Jr.: On August 21, 1945, physicist Harry K. Daghlian Jr. accidentally dropped a tungsten carbide brick onto a plutonium core while conducting a criticality experiment at the Los Alamos Laboratory in New Mexico. This caused a criticality accident, leading to an uncontrolled release of radiation. Daghlian received a lethal dose of radiation and died from acute radiation sickness on September 15, 1945.

Louis Slotin: On May 21, 1946, physicist Louis Slotin was performing another criticality experiment using beryllium and plutonium core at the Los Alamos Laboratory. During the experiment, he inadvertently allowed too much of the materials to come into proximity, leading to an unintended criticality. Slotin quickly separated the materials and shielded others nearby, but he absorbed a high dose of radiation. He succumbed to acute radiation sickness on May 30, 1946.

Oppenheimer says this because he's giving a rousing victory speech after all the hard work on the project paid off. In reality, Oppenheimer was distraught over the creation of the bomb and the heavy death toll it wrought. While Oppenheimer's original motivation was to beat the Nazis to the creation of such a weapon and the fact that Oppenheimer was Jewish, another motivation for him to want to create the bomb to stop the Nazis.

As long as they agree to keep everything they witnessed a secret, it's possible. It's also possible they remained under surveillance after they left the project. Finally, they may have left the project, but werent allowed to leave the base.

They certainly weren't best buds. But there was a mutual respect and adoration between them.

The marbles represent how much Uranium and Plutonium were being made by the 2 sites - Oakridge, and Hanford. There were 2 methods that could be used to make the bomb using either Uranium or Plutonium. The glass represented the potential size of Fissonable material needed for each Bomb.

Plutonium was represented in the smaller Glass as it required less to make although it was harder to make. While the bigger one represented Uranium which required more.

Whilst obviously an incredible genius he didn't actually invent the atomic bomb, that was more of a group effort. Oppenheimer's strengths were his skills as a co-ordinator, mentor and mediator between the various scientists and the military. He was also extremely innovative, in the film he is referred to as the "King of the Improvisers". For instance refining uranium required vast amounts of copper which was in extremely short supply in wartime America as it was used to manufacture brass for munitions. So the Manhattan Project borrowed millions of dollars worth of silver bullion from the US Mint and utilised this instead (this led to the legend of "Teller's Treasure", that the now radioactive silver was buried in the desert to cool off but due to the devastation caused by the later H-bomb tests the exact location was lost and it was never recovered). Oppenheimer was always uncomfortable with the title whilst Edward Teller revelled in being called "The Father of the H-bomb".

They had enough materials for 3 bombs. After the test bomb, we see the materials for the two other bombs used being trucked off.

That represents how high of a Security clearance Oppenheimer had been given by the DOE Dept. of Energy. Q clearance is pretty high up so he has access to Top Secret information, restricted information, both past and current and National Security Information as well. Put it this way, in order to be involved with the project, you had to have clearance high enough to have knowledge of top secret US projects such as building the Atomic Bomb.

"Blacklisted" is a pretty vague term. In hollywood, for actors it usually means they're not hired for many acting roles anymore because their name attached to the project could lead to people not seeing it.

Being a producer can be as simple as acquiring money for the film. So a behind the scenes role can be easier to acquire.

Because there had been reports the Nazis were building such a bomb themselves. So it became a race to complete it first. Essentially, the bomb would have eventually been created regardless, so it was a case of if he didn't build it, someone else would.

Also, the challenge and opportunity of creating such a weapon of awesome power, using new technology may have been too tempting to step away from. To quote Ian Malcolm in Jurassic Park; "The scientists were so preoccupied with whether or not they could, they didn't stop to think if they *should*."
