N2 - The paper by Castaing et al. (J. Fluid Mech., vol. 204, 1989, pp. 1–30) on turbulent Rayleigh–Bénard convection has been one of the most impactful papers on the subject – not by giving the right and complete answers but by developing versatile concepts and by asking the right questions, namely: (i) What is the overall flow organization? (ii) What is the dependence of the Nusselt number Nu (the dimensionless heat transport) on the Rayleigh number Ra (the thermal driving strength)? (iii) What is the ultimate state of turbulence for extremely large Ra? Thanks to Castaing et al. having asked the right questions, the field has made tremendous progress over the last 35 years.
