Nigel Oscar Weiss FRS (born 16 December 1936)[1] is an astronomer and mathematician, and leader in the field of astrophysical and geophysical fluid dynamics. He is currently Emeritus Professor of Mathematical Astrophysics at the University of Cambridge.[3][4][5]
Education
Born in South Africa, Weiss studied at Hilton College, Natal, Rugby School and Clare College, Cambridge, and has been a fellow of Clare College since 1965.
Career
In 1987 he became Professor of Mathematical Astrophysics at the University of Cambridge.
Between 2000 and 2002 he was President of the Royal Astronomical Society, and in 2007 was awarded the Gold Medal, the society's highest award.[3]
Research
Weiss has published extensively in the field of mathematical astrophysics, specialising in solar and stellar magnetic fields, astrophysical and geophysical fluid dynamics and nonlinear dynamical systems.[3]
In 1966 he was the first to demonstrate and describe the process of 'flux expulsion' by which a conducting fluid undergoing rotating motion acts to expel the magnetic flux from the region of motion, a process now known to occur in the photosphere of the Sun and other stars.[6]
Awards and honours
Weiss was elected a Fellow of the Royal Society (FRS) in 1992.[1] His nomination reads
| “ | Professor Weiss is distinguished for his work in the theory of convection, for developing appropriate numerical techniques, and for pioneering their use in precise numerical experiments to gain a qualitative and comprehensive understanding of the behaviour of complicated nonlinear systems. Among many notable achievements in this field, he has been instrumental in the identification of a period-doubling route to chaos in a system of partial differential equations describing doubly-diffusive convection. He has made wide-ranging studies of the magneto-convective processes occurring in the Sun and similar stars. In early work of lasting influence, he analysed the process of magnetic flux expulsion and the mechanism of concentration of magnetic field into ropes from which fluid motion is excluded. In recent work, he has initiated a program of research in the field of nonlinear compressible convection, an important step towards realistic modelling of stellar convection zones.[7] | ” |
