key term - Fritz Strassmann

Definition

Fritz Strassmann was a German chemist known for his pivotal role in the discovery of nuclear fission in uranium, which laid the groundwork for nuclear energy and atomic bombs. His work, conducted in collaboration with Otto Hahn, revealed that when uranium is bombarded with neutrons, it splits into lighter elements, releasing a significant amount of energy, a phenomenon that has profound implications for both energy production and weaponry.
