While researching a topic, a student has taken the following notes:
- Physicist Lise Meitner was a key collaborator with chemist Otto Hahn in Berlin for over three decades.
- In 1938, forced to flee Nazi Germany due to her Jewish heritage, Meitner relocated to Stockholm, Sweden.
- In December 1938, Hahn observed unexpected barium when bombarding uranium with neutrons but could not explain the result.
- Working in Sweden with her nephew Otto Frisch, Meitner calculated the energy released and provided the first theoretical explanation for nuclear fission in 1939.
- In 1944, Otto Hahn was awarded the Nobel Prize in Chemistry for the discovery, while Meitner’s indispensable theoretical contribution was overlooked by the committee.
