The diligent reader of this mini series on fields which comes to a close today will know what is coming: a Lagrange density will be defined, the Euler-Lagrange equation will be applied to create the field equations, and something will be said about gauges. This is the simplest of those seen so far, having only twelve terms in the Lagrange density instead of eighteen or twenty two. There is nothing grand about the process. No extra dimensions peak in from peek-a-boo branes. The simple math swings out the strange, making the GEM field equations glitter.There is one word in the title, unified, that will cause controversy. There already is an equation for gravity and EM known as the Hilbert-Maxwell Lagrange density: read more
