The role of hydrodynamic mixing in astrophysics is reviewed, emphasizingconnections with laser physics experiments and inertial confinement fusion(ICF). Computer technology now allows two dimensional (2D) simulations, withcomplex microphysics, of stellar hydrodynamics and evolutionary sequences, andholds the promise for 3D. Careful validation of astrophysical methods, bylaboratory experiment, by critical comparison of numerical and analyticalmethods, and by observation are necessary for the development of simulationmethods with reliable predictive capability. Recent and surprising results fromisotopic patterns in presolar grains, 2D hydrodynamic simulations of stellarevolution, and laser tests and computer simulations of Richtmeyer-Meshkov andRayleigh-Taylor instabilities are discussed, and related to stellar evolutionand supernovae.Comment: 9 pages(latex), 2 figures(postscript), invited review in gzipped tar file, requires psfig.st
