18 Oct 2021: To see that Maxwell’s equations indeed follow from (1.20), we compute. (. ... x. ). You can check that Maxwell’s Lagrangian (1.23) is indeed invariant.

18 Oct 2021: N. (2.63). which gives us back the ideal gas law. 2.3 Maxwell Distribution. ... 3. /. 2. This is the Maxwell distribution. It is sometimes called the Maxwell-Boltzmann distribution.

18 Oct 2021: 6.1 Maxwell’s Equations. The Lagrangian for Maxwell’s equations in the absence of any sources is simply. =. -. ... 6.571). In Coulomb gauge we can rewrite the Maxwell part of the Lagrangian as.

16 Oct 2021: 3.2.5 The Maxwell Action. Let’s briefly turn to some physics. We take the manifold. ... F. μ. ν. F. μ. ν. This is the Maxwell action, now generalised to a curved spacetime.

16 Oct 2021: It’s worth pausing to see why this analogy does not continue when objects move and the resulting Einstein equations of general relativity are considerably more complicated than the Maxwell equations ... Indeed, in the full Maxwell equations. ρ. e.

18 Oct 2021: But why then didn’t Faraday, Maxwell and other classical physicists find it useful to introduce the concept of matter fields, analogous to the electromagnetic field? ... The field theories of Maxwell and Einstein remedy the situation, with all

16 Oct 2021: μ. and. ν. , nor gauge invariant. That’s not such a surprise as it’s also true for Maxwell theory. ... In Maxwell theory, such a term can be added to make the resulting energy-momentum tensor both symmetric and gauge invariant.

16 Oct 2021: K. obeys something very similar to the Maxwell equations,. d. F. =. ... 0. But these are the vacuum Maxwell equations in the absence of any current, so we would expect any “electric charge” to vanish.

18 Oct 2021: 4 Classical Thermodynamics. 4 Classical Thermodynamics. “Thermodynamics is a funny subject. The first time you go through it, you don’t understand it at all. The second time you go through it, you think you understand it, except for one or two

10 Dec 2021: CLERK-MAXWELL, LL.D., F.R.S. The first part of the growth of a physical science consists in the dis-covery of a system of quantities on which its phenomena ... Rankine and Clerk-Maxwell. Prof. Henrici and Mr.Merrifield, in their remarks on the
