Major rewrite

This is my version of the symmetry in physics article. I plan a major rewrite. I've started this by including some examples at the start. The third example needs a few more careful words of explanation. I plan to include a section on Symmetry groups, briefly describing some symmetry groups in physics with links shooting off to more technical articles. A discussion of spacetime and internal symmetries is essential here (there is an article on the former, but I don't think there is an article on the latter). A mention of continuous and discrete symmetries is needed too. I plan not to dispose of the earlier work in the article, but just to reorganise it so that the article reads a lot better; the skeleton of the article is there, but just needs a little 'fleshing out'.

Fleshed out the article somewhat. Still need to:

• Mention examples of local and global symmetries.

• Mention the eightfold way, SU(3), SU(2) and U(1) (and electroweak gauge group).

• Give symmetries of Maxwell's equations (or link to an existing article) - especially completion of Maxwell's equations to include magnetic monopoles (+ a discussion of pros and cons of this completion).

• Include symmetry in relativity (principle of relativity).

• Lagrangians.

Of course, other stuff needs to be mentioned too. MP (talk) 14:52, 1 January 2006 (UTC)
