The David Crighton Medal

摘要

The Councils of the Institute of Mathematics and itsApplications and of the London MathematicalSociety have awarded the 2009 David CrightonMedal for services to mathematics and to the mathemat-ical community to Professor Keith Moffatt, FRS,FRSE, (Hon) FIMA, Emeritus Professor of Mathemat-ical Physics at the University of Cambridge, in recogni-tion of his contributions to fluid dynamics andmathematical modelling and for his leadership in manypositions in UK and international mathematical organisations.Keith Moffatt is one of the world's pre-eminent applied mathe-maticians, who has, over a research career spanning 50 years,made land-mark contributions to an extraordinarily wide rangeof problems in fluid mechanics. Seminal works include his cre-ation of the new sub-discipline of topological fluid mechanics, inwhich he used fundamental notions from topology to shed lighton the dynamics of turbulent flow; his discovery of unsteady cir-culatory motion in low-Reynolds number corner flow (theso-called Moffatt eddies); and in magnetohydrodynamics, inwhich he elucidated the interaction between fluid turbulence andmagnetic fields.
