Abstract
Recent surprising results on very large Rayleigh-number thermal convection are presented and discussed. For Rayleigh numbers beyond about \(10^{14}\) the scaling of the Nusselt number as well as the profiles are determined by turbulent boundary layers, though these are extremely thin. The theoretical interpretation is well consistent with the experimental data measured with the high pressure convection facility in Göttingen by Guenter Ahlers et al.
Dedication Ladies and Gentlemen, dear colleagues and friends, it is with my greatest pleasure to address our Nestor and always stimulating academic advisor, Professor Hermann Haken, with my sincerest congratulations on the occasion of his 85th birthday. I wish to express my warmest thanks and appreciation for his leadership and his guidance. Thank you, Hermann, for being our ideal over all the years, kindly accept all my, all our best wishes for you!
