I don't understand one bit of this stuff! —Preceding unsigned comment added by Graham P. (talk • contribs) 22:46, 20 February 2005

[edit] Holy crap
No kidding. Articles generally should start out with a simple explanation. This starts out with no explanation and is therefore a terrible article. The only person capable of understanding the article will already know the content. Meaning that someone who simply wants to begin understanding it has nowhere to go except away from Wikipedia. My lowest rating. 1 of 10 stars. —Preceding unsigned comment added by 192.103.41.201 (talk) 23:36, 15 January 2006
[edit] Comment on Context Tag
I added the context tag. I had followed the Lorentzian manifold link (redirected to here) on the General relativity page hoping the get a better understanding of the subject. However, this article is difficult to follow and could use improvement. Judging by the comments above I'm not the only one. Ryan Roos 22:40, 1 December 2006 (UTC)
- Do you have a specific question you wish to ask? If you haven't studied Riemannina geometry, you won't magically grok this article no matter how much "context" is added to it. FWIW, this article is nt well written, but it says nothing that is actually complicated, this is pretty introductory material. linas 23:41, 1 December 2006 (UTC)

- I suspect most of the complaints regarding this page are coming from people who arrive here from a general relativity article looking for a definition of a Lorentzian manifold when they don't even know what a manifold is, much less a Riemannian one. Calabi-Yau manifold gets similar complaints. Perhaps its necessary to fork off Lorentzian manifold to its own page and start the discussion at a much lower level. -- Fropuff 00:27, 2 December 2006 (UTC)
- linas and Fropuff thank you for your thoughtful replies. I found the discussion on the Talk:Calabi-Yau manifold of the technical tag that had been used there helped to resolve some of my problems with the article. The main basis of my concern was result my lack of knowledge of manifolds. (On a side note linas I enjoyed following several of the links on your user page) Ryan Roos 02:04, 3 December 2006 (UTC)

[edit] Lorentzian Manifold
I'd like to separate out an article about Lorentzian manifolds. This could emphasise their use in physics and in general relativity. It would link to pseudo-Riemannian manifold. What do people think? SJ 17.00 5 December 2007. —Preceding comment was added at 17:13, 5 December 2007 (UTC)
