Definition

Proper noun: - Otto Robert 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 described the potential for an explosive chain reaction.

Examples of Usage
  • Proper noun:
    • Otto Robert Frisch and Lise Meitner's interpretation of Hahn's data was a pivotal moment in nuclear physics.
    • The physicist Otto Robert Frisch worked on the Manhattan Project during World War II.
    • In his memoir, Otto Robert Frisch recounted the discovery of nuclear fission.
Advanced Usage
  • "The Frisch-Peierls memorandum": A secret 1940 document co-authored by Otto Robert 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.
    • The Frisch-Peierls memorandum alerted the British government to the possibility of building an atomic weapon.
Variants and Related Words
  • Frisch (noun): A common shortened reference to Otto Robert Frisch within historical and scientific contexts.
    • Frisch later headed the nuclear physics division at the Cavendish Laboratory.
  • Nuclear fission (noun phrase): The term he co-invented with Lise Meitner to describe the splitting of a heavy atomic nucleus.
Synonyms
  • Physicist: A scientist who specializes in physics. (This is his profession, not a direct synonym for his name.)
  • Scientist: A person who is studying or has expert knowledge of one or more of the natural or physical sciences.
Related Phrases
  • To coin the term "nuclear fission": The specific achievement of naming the process he and Meitner explained.
    • Otto Robert Frisch is credited with helping to coin the term "nuclear fission".
Related Idioms
  • A chain reaction: A series of events where each event causes the next. While this is a general term, its most famous scientific application in nuclear physics is directly linked to Frisch's work.
    • Otto Robert Frisch was among the first to describe a nuclear chain reaction.
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)
