- Puts forward the theory of beta decay that introduces the weak interaction. First theory to explicitly use neutrinos and particle flavour changes.
- Created first nuclear reactor
- Experimented with inducing radioactivity with recently discovered neutrons, discovered slow neutrons were easily captured.
