Gradient theorem - Wikipedia
WebMain article: Divergence. In Cartesian coordinates, the divergence of a continuously differentiable vector field is the scalar-valued function: As the name implies the divergence is a measure of how much vectors are diverging. The divergence of a tensor field of non-zero order k is written as , a contraction to a tensor field of order k − 1. Webthere is an electric potential Φ such that E = −∇Φ; hence ∇ . E = ρ/ 0 gives Poisson’s equation ∇2Φ = −ρ/ 0. In a region where there are no charges or currents, ρand J vanish. Hence we obtain Laplace’s equation ∇2Φ = 0. Also ∇×B = 0 so there exists a magnetostatic potential ψsuch that B = −µ 0∇ψ; and ∇2ψ= 0 ... potato soup with ham bone recipe

WebMIT - Massachusetts Institute of Technology WebGeneral Relativity is an extremely successful theory, at least for weak gravitational fields; however, it breaks down at very high energies, such as in correspondence to the initial singularity. Quantum Gravity is expected to provide more physical insights in relation to this open question. Indeed, one alternative scenario to the Big Bang, that manages to … Web2 The Real Scalar Field All that is now missing is the fact that momentum p and position x should be 3-vectors and so the eld φ is a function φ(x;t) which we usually just write as φ(x), understanding that x refers to a 4-vector (x;x0), with x0 =t. The Lagrangian is now expressed as an integral over all space L = Z d3xL; with L = 1 2 φ 2 1 2 ... tot in football stats
