I will discuss the ups and downs of our emerging knowledge of turbulent convection in the Sun, occurring at Rayleigh numbers estimated to be as high as 10^{24}, by comparing and contrasting laboratory experiments (our own and those of many other researchers) with helioseismology results. I will attempt to identify a few specific questions of broad interest, and show how, despite much progress; a lot remains to be known.


After two years of post-doc work at Johns Hopkins University, Sreeni taught at Yale for twenty-two years from 1979, as the Harold W. Cheel Professor from 1988, with appointments in the Departments of Mechanical Engineering, Physics, Applied Physics and Mathematics. In 2002, he moved to the University of Maryland as Distinguished University Professor of Physics and Engineering, and served for a year and a half as the Director of the Institute for Physical Science and Technology. He was then enticed to take the Directorship of the International Center for Theoretical Physics in Trieste, Italy, where he held a concurrent professorship in the name of the Centerís founding director, the late Nobel Laureate Abdus Salam. He is presently University Professor and Eugene Kleiner Chair in New York University, with joint appointments in the departments of Physics and Mechanical Engineering and the Courant Institute of Mathematical Sciences. He is also the President of the former Brooklyn Polytechnic and the Dean of NYU Engineering. Sreeni is a member of the US National Academy of Sciences and the US National Academy of Engineering, fellow the American Academy of Arts and Sciences, the Indian Academy of Sciences and the Indian National Science Academy, the Academy of Sciences for the Developing World, the African Academy of Sciences and, most recently, the Accademia Nazionale dei Lincei in Italy, arguably the world's oldest academy in the world, which boasts Galileo as one of its former members. He has received several honors such as the Guggenheim Fellowship and several medals from American Physical Society as well as the American Association for the Advancement of Sciences, etc.
