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
