AB: A poster format is explored that is designed to pull the viewer in by presenting, in an open question to the viewer format, very simple and intuitive ideas that are subsequently, i.e., at the flip of panel, shown to be not as intuitive as the viewer may have thought. To make the examples scientifically concrete we use recent results related to the cooling efficiency of thermal convection. We explore the intuitive ideas that: 1) increased insulation above a convecting fluid lowers the heat flow rate out of the fluid; 2) a lower bulk averaged thermal Rayleigh number in a fluid with depth-dependent viscosity leads to a lower heat flow rate out of the fluid.
