Berkeley Physics congratulates John Clarke, professor of the graduate school in physics and a Berkeley Lab scientist on being named to the American Philosophical Society. Professor Clarke is noted for his work on superconductivity, particularly the development and application of ultrasensitive SQUIDs (superconducting quantum interference devices). He has used SQUIDs in many applications, including detection of NMR signals at ultralow frequencies; geophysics; nondestructive evaluation of materials; biosensors; detection of dark matter; and observing “qubits” for a potential quantum computer.
Clarke is a fellow of the Royal Society of London, the American Physical Society, the American Association for the Advancement of Science and the Institute of Physics (UK). He has been a Sloan Foundation Fellow, a Guggenheim Fellow and a Miller Professor. In 1987, he was named California Scientist of the Year and was awarded the Fritz London Prize for research in low-temperature physics. In 1998, he received the American Physical Society’s Joseph F. Keithley Award for Advances in Measurement Science and, in 1999, the National Academy of Sciences’ Comstock Prize for Physics. He was awarded the Hughes Medal of the Royal Society in 2004, and was the UC Berkeley Faculty Research Lecturer in 2005.
The APS, the first learned society in the United States, has played an important role in American cultural and intellectual life for more than 250 years. A scholarly organization, it promotes useful knowledge in the sciences and humanities through excellence in scholarly research, professional meetings, support of young scholars, publications, library resources, a museum and community outreach.
