Most friends know this, but what many people don't know is that the company that developed the atomic bomb only charged the US military department a dollar for research and development.
A dollar to develop an atomic bomb
Many people will find this place incredible. They believe that even in the 1940s, or at any time, the investment in such a huge scientific research project will be infinite and incalculable. How can it be a dollar?
Einstein and Oppenheimer.
At that time, Einstein had to flee from Germany to the United States because of his Jewish identity, but he still had contacts with German scientists. In this process, he noticed the clues of Hitler's research on atomic bombs in Germany, so he informed the US military of his research on atomic bombs in Germany. This suddenly caused panic in the United States. If Hitler mastered the atomic bomb, the consequences would be unimaginable. After listening to the advice of many American scientists, including Einstein, the United States decided to speed up the development of the atomic bomb.
Roosevelt
So in 1942, Roosevelt, then president of the United States, launched a top secret project-Manhattan Project, and began to develop atomic bombs. He handed this research and development task to DuPont, a famous American company. This DuPont company first studied black powder, and later studied some chemicals and energy. Especially during the First World War, because of their research results, the United States made a lot of war money. Dupont is not only strong, but also cooperates closely with the US military.
