Again UC Berkeley is on the cutting edge in both engineering and social science.  The Department of Sociology collaborated with the Department of Mechanical Engineering to develop a class to address gender fluidity.  Rather than trying to teach the concept with words, they used equations to describe the complex concept.

Though the Engineering Department could not understand the requirements and the Sociology Department could not understand the physics, the versatility of the Navier-Stokes equations came to the rescue.  These fundamental equations of fluid dynamics were the perfect way to describe the nonlinear concept, which also has no analytical solution.  The adapted equations now address inertial forces, social pressure forces, and external forces. 

Furthermore, since the Navier-Stokes equations are already considered one of the Clay Mathematics Institute’s Millennium’s Problems (the seven most pressing unsolved problems in all of mathematics), the adapted equations are a perfect poetic intersection of physics and Millennial social science.  There is a $1M USD prize for anyone who can prove whether there are always “smooth” solutions to the equations, aka whether they behave in a predictable, sensical way.  Humanity awaits the answer!
