J. Robert Oppenheimer: Contributions and Career
J. Robert Oppenheimer had a significant impact on the field of theoretical physics in the United States. He played a crucial role in the development of the atomic bomb during World War II as the scientific director of the Manhattan Project. His leadership and contributions in this project helped establish the United States as a global leader in nuclear science and technology. Oppenheimer's work greatly influenced the understanding of nuclear physics and the application of quantum mechanics to the field. His research on the behavior of subatomic particles and the theory of black holes also made lasting contributions to theoretical physics. However, Oppenheimer's involvement in the Manhattan Project also led to controversies, including his security clearance being revoked during the McCarthy era due to allegations of communist connections.
Brussels shooting: Police kill attacker who murdered Swedes
Police in Brussels have fatally shot the man responsible for killing two Swedish nationals in a shooting on Monday.
