Fundamentals of Hydrodynamics and Thermodynamics

This chapter investigates hydrodynamics through particle behavior, introducing key concepts such as the Maxwell-Boltzmann distribution and the different types of fluids. It highlights the significance of conservation laws and discusses the evolution of fundamental equations, including the Navier-Stokes equations, while exploring non-equilibrium states in various systems. The chapter culminates with an analysis of electron flow in materials like graphene, illustrating the complexities of hydrodynamic behaviors and their parallels in stellar phenomena.
