Fluids and Electromagnetism

This lecture covers the concepts of closed and non-closed surfaces, divergence theorem, flow and flux of vector fields, Stokes theorem, and applications in fluid dynamics and electromagnetism. It also discusses coordinate systems, scalar fields, gradient theorem, and useful formulas. The lecture delves into fluid properties, such as mass density, fluid at rest, and fluid flow, emphasizing the system of particles and their behavior in different coordinate systems.
