Résumé :
I will start by giving an overview of the recent successes of a dynamical systems approach to understanding turbulent transition in shear flows using pipe flow as the primary example. I will then go on to discuss some recent ideas aimed at trying to extract the `minimal seed’ of turbulence. That is, the `smallest’ disturbance to a shear flow which will trigger turbulence.
