Presenting Dr. Barry Barish:
Einstein, Gravitational Waves and a New Science
Abstract: Albert Einstein predicted the existence of gravitational waves 100 years ago, but the effects are so tiny that even Einstein thought they could never be detected. After 40 years of controversy, theorists finally developed a consensus that they really do exist. Then the problem became whether experimental physicists could develop instruments sensitive enough to actually detect them? The Laser Interferometer Gravitational-wave Observatory (LIGO), using exquisitely sensitive techniques, has made the dramatic observations of gravitational waves coming from the collision of two Black Holes and more recently, Binary Neutron Stars. These observations have opened a totally new window on the universe. The history, techniques and scientific implications will be discussed.

Dr. Barry Barish is an American physicist who was awarded the 2017 Nobel Prize in Physics for his work on the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the first direct detection of gravity waves. Barish received his bachelor’s and doctorate in physics at the University of California, Berkeley. He was a research fellow at Berkeley and then became a research fellow at Caltech, where he spent the remainder of his career. He became professor emeritus in 2005. He worked on experiments at the Stanford Linear Accelerator Center, and became involved in the search for magnetic monopoles. He also headed a team to design an experiment for the Superconducting Super Collider (SSC), but the U.S. Congress cancelled that project. He went on to become LIGO principal investigator, and eventual director, reviving LIGO from doubts expressed by the NSF. On September 14, 2015, Advanced LIGO made the first detection of gravity waves from a pair of black holes that spiraled into each other 1.3 billion light-years away.
