We all know warm air rises, right? It happens because when you add energy, molecules move around more, taking up more space; ...
The spectrum of the simplest 1D convection-diffusion operator is a discrete subset of the negative real axis, but the pseudospectra are regions in the complex plane bounded approximately by parabolas.
