Definition

Proper noun: - Otto Frisch: A British physicist of Austrian birth. He is most noted for his collaborative work with Lise Meitner in 1938, where they provided the first theoretical explanation for the results of Otto Hahn's experiments, coining the term "nuclear fission" for the process. He also calculated and warned of the explosive potential of a nuclear chain reaction.

Usage Examples
  • Proper noun:
    • Otto Frisch and Lise Meitner correctly interpreted Hahn's data as evidence of nuclear fission.
    • The physicist Otto Frisch worked on the Manhattan Project during World War II.
    • A key figure in 20th-century physics was Otto Frisch.
Advanced Usage
  • "The Frisch-Peierls memorandum": A secret 1940 document co-authored by Otto Frisch and Rudolf Peierls. It was the first technical document to conclude that an atomic bomb using uranium-235 was feasible and to estimate its critical mass and devastating effects.
    • The Frisch-Peierls memorandum significantly influenced the British and American decision to pursue an atomic weapon.

  • "To coin the term 'nuclear fission'": The act of inventing and first using the specific phrase to describe the newly discovered process.
    • Meitner and Frisch coined the term 'nuclear fission' in their landmark paper.
  • "Chain reaction": A series of reactions where a product from one reaction initiates further reactions. Frisch described the explosive potential of a nuclear chain reaction.
    • Frisch understood that an uncontrolled chain reaction could lead to a massive explosion.
Noun
  1. British physicist (born in Austria) who with Lise Meitner recognized that Otto Hahn had produced a new kind of nuclear reaction which they named nuclear fission; Frisch described the explosive potential of a chain nuclear reaction (1904-1979)
