Richard A. Muller January 6, 1944 (1944-01-06) (age 65) of San Francisco, California, U.S., is a physicist who works at the University of California, Berkeley and Lawrence Berkeley National Laboratory. Dr. Muller began his career as a graduate student under nobel laureate Luis Alvarez doing particle physics experiments and working with bubble chambers. During his early years he also helped to cocreate accelerator mass spectroscopy and made some of the first measurements of anisotropy in the cosmic microwave background. Subsequently, Dr. Muller branched out into other areas of science, and in particular the earth sciences. His work has included attempting to understand the ice ages, dynamics at the core-mantle boundary, patterns of extinction and biodiversity through time, and the processes associated with impact cratering. One of his most well known proposals is the Nemesis hypothesis suggesting that the sun could have an as yet undetected companion star, whose perturbations of the... less
