SCIENCE - New research helps to show how turbulence can occur without inertia

For more than a century, the field of fluid mechanics has posited that turbulence scales with inertia, and so massive things, like planes, have an easier time causing it. Now, new research has shown that this transition to turbulence can occur without inertia at all.
