How did the atomic bomb change the world?

The atomic bomb changed the course of history, saving the U.S. from losing to Japan. This bomb had an impact on the world both metaphorically and physically. No such weapon had combined science and technology so smoothly other than the device that, ever since its creation, blew away Hiroshima and Nagasaki. On August 2, 1939, Einstein proposed an interesting to President Franklin D. Roosevelt. This idea, called the atomic bomb, would change the lives of everyone. Making it was easier said than done, though. They needed a team of scientists: Robert Oppenheimer, David Bohm, Leo Szilard, Eugene Wigner, Felix Bloch, Otto Prisch, Rudolf Peierls, Niels Bohr, Emilio Segre, James Franck, Enrico Fermi, Klaus Fuchs, and Edward Teller. Then they had to find U-235, which looked exactly like U-238, a useless material. The process was hard, especially since only mechanical methods worked. Finally, after an extraction system, a magnetic separation, and a gas centrifuge, all that was needed to be done was to test the entire concept in the deserts of Jornada del Muerto (about money). The Gadget was quickly put together. Upon detonating, the white blaze shot through the still-dark sky, slowly transforming into an orange ball of fire shooting up 360 feet per second. The mushroom cloud took form at 30,000 feet. Beneath the grim cloud, all that remained in the soil at the blast site were fragments of jade green radioactive glass created by the heat of the reaction (about money). With a nuclear
