alvarez
(āl’və-rěz’)
american physicist who studied subatomic particles. alvarez built a device called a hydrogen bubble chamber that made it possible to -n-lyze the reactions occurring between atomic nuclei inside it. his observations led to the theory that protons, neutrons, and electrons are made of quarks. alvarez won a 1968 n-bel prize for physics for this work. with his son, geologist walter alvarez (born 1940), he later developed a theory that the extinction of dinosaurs was caused by climate changes resulting from a giant asteroid striking the earth.
