An excerpt for credibility:
> Those Navier-Stokes equations are what I did my PhD on. They are basically Isaac Newton’s second law of motion: F=ma, but applied to fluids. They are, in my not entirely unbiased opinion, staggeringly beautiful, able to articulate everything from the drip of a water droplet on a leaf and the churn of an entire atmosphere to the gases swirling around in a galaxy in the sky.
