- Mendeleev's observation of periodicity; recommended that uranium be studied more due to the rays that came off it based on Becquerel's accidental discovery by putting pitchblende on a photographic plate in a drawer for storage.
- Curies' experiments to measure uranium's power - used radioactive elements to ionize air that would conduct electricity. They got uranium from pitchblende and thought that the ore wouldn't be as radioactive but it was more radioactive. They then isolated polonium and radium and confirmed their unique Fraunhofer lines. Warm blue light and heat from radium was sought as a therapeutic tool - bad idea... Energy from matter? How is this done... connection to E=mc2.
