Minimal norm of an operator perturbation that can destabilize a plane Couette, plane Poiseuille, or pipe flow, as a function of R. The dots mark the approximate lower Reynolds numbers at which transition to turbulence may be observed, and it is notable that they all lie at approximately the same height.
