Otto Robert Frisch

Otto Robert Frisch was a physicist known for his work on nuclear fission, the process where an atomic nucleus splits, releasing a massive amount of energy. In 1939, he and his aunt, Lise Meitner, developed the theoretical explanation for how fission occurs when heavy elements like uranium are bombarded with neutrons. They described how this reaction could lead to a chain reaction, which is the principle behind nuclear reactors and atomic bombs. Frisch's contributions significantly advanced our understanding of nuclear physics and had profound implications for energy production and warfare.
