Study Notes

Early Life and Education

  • Lise Meitner was born in Vienna to a Jewish family
  • Her father was a lawyer who created an intellectually stimulating environment
  • At age 8 she showed an interest in mathematics and science
  • She received private tutoring as girls were barred from state schools
  • She passed the University of Vienna entrance exam at 23
  • She was tutored by Ludwig Boltzmann
  • She was the second woman to receive a doctorate in physics from the University of Vienna

Career Highlights

  • Meitner moved to Berlin and worked as a departmental assistant at Max Planck's physics institute
  • She became head of the physics department at the University of Berlin
  • She was awarded the Leibniz Medal and became the supervisor of the physics section
  • She fled Nazi Germany in 1938 and settled in Sweden
  • She published the theory of nuclear fission with her nephew Otto Frisch
  • She received the Enrico Fermi Award with Otto Hahn and Fritz Strassmann in 1966

Early Career and Radiation Research

  • Meitner was invited by Max Planck to conduct postdoctoral studies at the University of Berlin
  • She worked without salary alongside leading physicists including Einstein
  • She worked with Otto Hahn studying radioactive elements and discovering new isotopes
  • She became the first female physics professor in Germany in 1926

Enrico Fermi and Nuclear Chain Reaction

  • Enrico Fermi created the first working nuclear chain reaction in 1942
  • He had achieved nuclear fission in 1934
  • Meitner’s and Otto Frisch’s work in 1939 prompted further nuclear research
  • This research persuaded the US military of the potential for a nuclear bomb

Nuclear Discovery

  • Meitner received a report from Hahn about unusual results of research on nuclear uranium
  • Uranium seemed to “burst” and form barium when bombarded with neutrons

Personal Context and Nazi Era

  • Meitner converted to Christianity in 1908
  • She was increasingly vulnerable throughout the Nazi era as a Jewish woman
  • She fled to Sweden in 1938 after Austria was annexed by Germany

Lise Meitner on Nuclear Fission

  • Meitner worked with Otto Frisch to understand fission
  • When uranium atoms split, the resulting nuclei weighed less than the original
  • This mass was converted into energy following Einstein’s Theory of Relativity
  • Meitner and Frisch published their findings in 1939
  • This discovery was quickly followed by development of the atomic bomb
  • Meitner did not receive the 1944 Nobel Prize, which was awarded only to Otto Hahn
  • She remained optimistic and stated that science can bring joy and satisfaction

Hahn’s Experiment (1938)

  • Hahn’s 1938 experiment included bombarding a nucleus with a neutron
  • The bombardment caused the nucleus to split and release energy

Diagram Description

  • The diagram shows a large nucleus splitting into two smaller nuclei, accompanied by a large burst of energy
  • The splitting occurs after being bombarded with a neutron
