Abstract:- Fluid flow is laminar, or turbulent, or something in-between. Honey normally flows in smooth laminar fashion but a volcanic eruption is fierce and turbulent. Laminar flow is efficient and turbulence is wasteful. But turbulence has its uses, like when we want sugar to mix into our tea. 

When we knew all the relevant equations for laminar-turbulent transition more than a hundred years ago, why have we still not understood it theoretically? And experimentally: is it really so hard to make fluid flow through a pipe and make a few measurements? We'll talk about all this, and about the questions our group is asking on this topic.
