faculty members and 100 graduate students. The Department of Physics and Astronomy offers both Ph.D and master's degrees in physics, as well as an interdisciplinary degree in chemical and material physics. The Department of Earth System Science offers a Ph.D. degree program in earth system science. Associated bodies Student organizations The American Chemical Society Student Affiliates is the student-run Chemistry Club at UCI. It provides academic and career guidance to undergraduates, as well as opportunities to meet and interact with guests or professors from the field of Chemistry. The Anteaters Mathematics Club is the student-run Mathematics Club at UCI. It provides weekly guest lectures from professors, graduate students, or others in the field of Mathematics. The Anteaters Math Club also provides a quarterly panel with Mathematics professionals for a Q&A with students. The UCI Earth System Club is a student-run club based on Earth System Science. The club provides students with information regarding the Earth System Science major as well as networking opportunities. The Society of Physics Students at UC Irvine is UCI's chapter of the Society of Physics Students. The club conducts and organizes events to help students develop interest in physics, as well as providing areas for study. The Astronomy Club at UCI is a student-run club based on Astronomy. The club provides students with opportunities to meet other students interested in astronomy, and often utilizes the UCI Observatory as well as the grounds of Aldrich Park for stargazing. Nobel faculty Frank Sherwood Rowland Frank Sherwood Rowland was one of the original professors for the University of California, Irvine and became the first Chairman of the Chemistry Department in August 1964. He retired from his Chairman position five years later, but by 1973 Rowland changed his research focus from radiochemistry to atmospheric chemistry. In 1995, atmospheric chemist Rowland, along with his colleague Mario Molina received the Nobel Prize in chemistry for predicting and then proving that the ozone layer was being depleted by chlorofluorocarbons, common compounds found in aerosol sprays of the time. He continued to research their chemical effects on the environment. Frederick Reines Dr. Frederick Reines (1918-1998) along with his colleague Clyde Cowan in 1956 developed a method to detect, and confirmed the existence of, the neutrino, one of the most elusive subatomic particles. When he became the founding Dean of Physical Sciences of the University of California, Irvine in 1966 he brought his research along
