Oliver Penrose
Oliver Penrose is a British theoretical physicist and emeritus professor at Heriot-Watt University. His topics of interest include statistical mechanics, phase transitions in metals and the physical chemistry of surfactants. He is known for introducing the concept of off-diagonal [long-range order], important to the present understanding of superfluids and superconductors. He is also known for the Penrose criterion in plasma physics.
He was associated with the Open University for seventeen years and was a Professor of Mathematics at Heriot-Watt University in Edinburgh from 1986 until his retirement in 1994.
Penrose has worked in fundamental topics, which include understanding the physical basis for the direction of time and interpretations of [quantum mechanics].
