Robert Oppenheimer

J. Robert Oppenheimer was an American physicist best known for his role as the scientific director of the Manhattan Project, which developed the first atomic bombs during World War II. His work involved nuclear chemistry and physics, focusing on splitting atomic nuclei, a process known as nuclear fission, which releases vast amounts of energy. Oppenheimer's insights into atomic structure also contributed to the understanding of radioactivity and particle physics. After the war, he famously reflected on the moral implications of nuclear weapons, becoming a pivotal figure in discussions about the use of such powerful technology.
