How does a particle know how to behave?

Liquid density as a function of pressure and temperature, how to model experimental data of $\rho(p,T)$?

What does it mean for a law to be fundamental?

Highly nonlinear equations

Why can't the Navier Stokes equations be derived from first principle physics?
