Mathematicians Coax Fluid Equations Into Nonphysical Solutions

For nearly two centuries, all kinds of researchers interested in how fluids flow have turned to the Navier-Stokes equations. But mathematicians still harbor basic questions about them. Foremost among them: How well do the equations adhere to reality? A new paper set to appear in the Annals of Mathematics has chipped away at that question, proving that a once-promising class of solutions can…
