Arthur Guy Zajonc (pronounced /ˈzeɪ.ənts/ ZAY-ənts) (born 11 October 1949, Boston, Massachusetts) is a physicist and the author of several books related to science, mind, and spirit; one of these is based on dialogues about quantum mechanics with the Dalai Lama. Zajonc has been a professor at Amherst College since 1978. He has served as the General Secretary of the Anthroposophical Society in America. In January 2012, he became the president of Mind and Life Institute.
Zajonc received a B.S. in engineering physics from the University of Michigan in 1971. He received an M.S. (1973) and Ph.D. (1976) in physics at the University of Michigan as well. From 1976-1978 he was a research associate at the Joint Institute for Laboratory Astrophysics at the University of Colorado and the National Bureau of Standards, Boulder, Colorado.
Zajonc became an assistant professor of physics at Amherst College in 1978, and was promoted to associate professor in 1984 and full professor in 1991. In 2006 he became an Andrew W. Mellon Professor at Amherst. He retired from this position in 2011, and is presently Andrew W. Mellon Professor Emeritus at Amherst College.
From 1981-82 he was a Visiting Associate Professor of Physics at the École Normale Supérieure at the Laboratoire de Spectroscopie Hertzienne in Paris. In 1984 was a Visiting Research Physicist at the Max Planck Institute for Quantum Optics, Garching (Munich), Germany with H. Walther. In 1986 he was a visiting scientist at the Institute for Quantum Optics at the University of Hanover in Germany. In 1991 he was a visiting scientist at the Department of Physics at the University of Rochester with L. Mandel. In 1993 he was a Fulbright Professor at the University of Innsbruck, Austria teaching and doing research on the experimental foundations of quantum physics.
Zajonc was the physics department chairman at Amherst College for three different appointments: 1987-1989, 1998–2000, and 2005–present. Later that same year he was a Scholar-In-Residence at the Fetzer Institute. He was the Senior Program Director of the Fetzer Institute 1995-1997. He is the director for the Academic Program of the Center for Contemplative Mind in Society since 2004. This organization is composed of 1500 academics that support contemplative practices in higher education.
Zajonc held a number of dialogues with the Dalai Lama in 1997 which were later published in 2004 under his scientific coordination and editorship as Dalai Lama: The New Physics and Cosmology. He was moderator for the 2003 dialogue with the Dalai Lama at MIT.
