Navier–Stokes existence and smoothness saw 316x more Wikipedia readers than usual

What this article is

The question of whether the Navier–Stokes equations always have smooth solutions in three-dimensional Euclidean space, given some initial conditions and possibly an external force, has been a longstanding unsolved problem in mathematics since the early 20th century. The equations are a system of partial differential equations that describe the motion of a fluid in space. Although computational solutions to the Navier–Stokes equations are used in a large number of practical applications, there is no complete analytical understanding of the solutions. In particular, solutions of the Navier–Stokes equations often include turbulence, which remains one of the greatest unsolved problems in physics, despite its immense importance in science and engineering.

How this was measured

Views are Wikimedia's own pageview counts for en.wikipedia, filtered to agent=user so automated traffic is excluded. The baseline is the median of the previous 60 days, which is used instead of the mean so that an earlier surge cannot flatten a later one. The multiple is the day's views divided by that median.
