DESCRIPTION:Prof. Steve Tobias\, Applied Mathematics Department\, Universi
 ty of Leeds\nAbstract:\nThe eleven year solar activity cycle is a remarka
 ble example of regular behaviour emerging from an extremely turbulent syst
 em. The jets on Jupiter sit unmoving on a sea of turbulent eddies. Systema
 tic flows emerge from the interaction of eddies in experiments\, engineeri
 ng and geophysics. Phenomena in astrophysics and engineering often dis
 play organisation on spatial and temporal scales much larger than the tur
 bulent processes that drive them.\nAn outstanding problem of astrophysics 
 (and indeed other branches of nonlinear physics) is how to describe the st
 atistics of systematic behaviour emerging from the underlying chaos\, giv
 en that Direct Numerical Simulation of these objects is simply impossible.
  Here I shall introduce these fascinating phenomena and describe how metho
 ds from non-equilibrium statistical mechanics and many body quantum syste
 ms may be developed to give some insight into their behaviour.\n\nBio:\n
 Steve Tobias is Professor of Applied Mathematics at the University of Leed
 s. Having completed his PhD in DAMTP\, Cambridge on "Nonlinear Solar and S
 tellar Dynamos" in 1995\, he has been a Research Fellow of Trinity College
  Cambridge (1995-2000)\, a Research Associate of JILA\, University of Colo
 rado (1996-1998) and a Lecturer\, Reader and Professor at the University o
 f Leeds. His interests include nonlinear fluid dynamics (including magneto
 hydrodynamics) and its applications in experiments\, geophysics and astro
 physics via the application of methods from nonlinear dynamics and statist
 ical physics.
