Luis Walter Alvarez

Luis Walter Alvarez was an American physicist and inventor, renowned for his contributions to nuclear physics and particle physics. He won the Nobel Prize in Physics in 1968 for his work on bubble chambers that helped track subatomic particles. Alvarez is also famous for proposing the asteroid impact theory, suggesting that a giant asteroid caused the mass extinction event that wiped out the dinosaurs around 66 million years ago. His innovative ideas and research have had a lasting impact on our understanding of both fundamental physics and Earth’s history.
