Engineering students crying their way through partial differential equations while art majors watch movies? Tale as old as time! The Navier-Stokes equations are basically the mathematical equivalent of trying to describe why water splashes when you drop a rock in it, except it requires several pages of calculus and will probably make you question your life choices. Meanwhile, your friend gets to watch Ryan Gosling dance his way through LA. The universe is clearly playing favorites here. Fun fact: The Navier-Stokes equations are so complex that solving them in 3D space is one of the seven Millennium Prize Problems worth $1 million. So technically, if you ace that final, you might be a millionaire someday!
