In this video, we derive the electric field of a long uniformly charged rod using Gauss’s law. We choose an appropriate Gaussian surface, apply symmetry arguments, and walk through the math ...

Stevens Institute, Hoboken, reports the universal identity P²+K²=1, uniting polarization with entanglement across setups and ...

MEK1100 gives an introduction to the theory of scalar and vector fields with examples from fluid mechanics, geophysics and physics. The course contains gradient and directional derivative, divergence ...
