Actually, I only made up the fact that the critical exponents for liquid-gas at T_c and ferromagnets at T_c were known to be the same. This fact, while true, may have been established much later after Landau's theory (something like 1937). However, it would seem Landau had to have proposed this theory, in light of the many other existing theories, for a special reason. And the phenomenon of universality would have been sufficient motivation to give weight to this theory, which exploited basic features of the system such as symmetries and analyticity. I acknowledge that this paragraph requires fact checking. Wilgamesh 22:43, 18 Sep 2004 (UTC)

[edit] Good content, obscure name

I quite like the content of this article but think that the title choice could be improved. I was curious to look at the article because Landau had so many theories that I didn't know which one to expect! The best course of action I can think of would be to move the article to "second-order phase transition" and to plan to add other content later. BTW, I note that Phase_transition doesn't link here although it should. Alison Chaiken 04:38, 15 January 2006 (UTC)

Although he may have had many theories, I think this might be the only one explicitly called "Landau Theory." At least, so it is named in my statistical mechanics text books. If there are other theories actually called "Landau Theory" then we might need disambiguation, but I don't think this page should be moved. --Starwed 00:32, 7 March 2006 (UTC)
