Gamow discovered a theoretical explanation of alpha decay by quantum tunneling, invented the liquid drop model, worked on radioactive decay, star formation, stellar nucleosynthesis, Big Bang nucleosynthesis, and predicted the existence of the cosmic microwave background radiation and molecular genetics.
