I created this article some time ago (the anon was me) and realise that it needs a huge cleanup. Amongst many other things, perhaps examples of field equations from important theories should be included. MP (talk) 12:33, 3 January 2006 (UTC)

More cleanup ideas[edit]

Some ideas to give the article more substance:

  • Need a discussion of Poisson's equation for gravitation.
  • Mention something about Lagrangians (and conservation laws).
  • Describe the field equations for each theory in a little detail (mathematics used, analogies with other field equations, generalisations to other theories (e.g. n-dimensional Einstein field equations).
  • Field equations for theories of gravitation other than GR (emphasise similarities and differences).

I've gone some way in addressing these issues you've raised; the level of detail this article deserves is something I'm still considering.

Does Poisson derivation belong here?[edit]

Having just spruced up the first 2 subsections, I'm now not entirely sure that the outline derivation of Poisson belongs here. I put it there because I wanted to show how it came about from just considering force fields (as we had done above) with the additional machinery of potentials.
