There is some good ore in Canada and the former Czechoslovakia, while the most important source of uranium is Belgian Congo.In view of this situation you may think it desirable to have some permanent contact maintained between the Administration and the group of physicists working on chain reactions in America. A leading-edge research firm focused on digital transformation.On August 2, 1939, one month before the outbreak of World War II, Albert Einstein, the famous German-born physicist, signed a two-page letter to US President Franklin D. Roosevelt that would help bring the US into the nuclear arms race and change the course of history.Einstein was already in the US, having fled Germany when the Nazis came to power, and learned that German scientists had discovered nuclear fission, the process of splitting an atom's nucleus to release energy.The letter warned Roosevelt that "extremely powerful bombs of a new type" could be created in light of this discovery — and that these bombs would be capable of destroying entire ports and their surrounding areas.You can read it here, or read a full transcript at the bottom of this article:Roosevelt said, "Alex, what you are after is to see that the Nazis don't blow us up. Open to Members.

The hundreds of scientists on the project were forbidden from consulting with Einstein, because the left-leaning political activist was deemed a potential security risk.

One possible way of achieving this might be for you to entrust with this task a person who has your confidence and who could perhaps serve in an inofficial capacity.

However, such bombs might very well prove to be too heavy for transportation by air.The United States has only very poor ores of uranium in moderate quantities.

In an interview with 

Albert Einstein was famously a pacifist, but he signed a letter to US President Franklin D. Roosevelt in 1939 urging him to develop the atomic bomb. Whenever a system has an energy E, it automatically has the relativistic mass m=E/c2; whenever a system has the mass m, you need to assign it an energy E=mc2. His famous equation E=mc2 explains the energy released in an atomic bomb but doesn't explain how to build one. But Einstein was the father of the bomb in two important ways: 1) it was his initiative which started U.S. bomb research; 2) it was his equation (E = mc2) which made the atomic bomb theoretically possible.” Once the mass is known, so is the energy, and vice versa.
