I am not sure that this article meets the fundamental requirement of informing the uninformed. Lists of instability names might be useful for teaching a parrot a semblance of erudition, but taken out of their original contexts, add little to explaining the idea of instability. Rather than jumping straight into eigenvalues, which immediately gives the impression of Emperor's New Clothes, we should start with static stability, which could be extended to catastrophe theory. Dynamic instability may be explained with diagrams of divergent oscillations, followed by eigenvalues, followed perhaps by chaos. Gordon Vigurs10:08, 9 May 2006 (UTC)[reply]
I added most of the listed instabilities on the grounds that someone searching for one of them, will at least find a short desciption on what an instability is. Ideally it would be nice to be able to describe each one and differentiate them. At the very least, it confirms that a specific instabaility is indeed an instability. It's by no means ideal, but a start. --Iantresman10:37, 9 May 2006 (UTC)[reply]
Disambiguation
Unstable needs a disambiguity page, since there is an Adema album with that name that has an article in this wiki. The user can't reach that page through Unstable, only through Unstable_(album). Which is pretty bad for someone who is not familiar with how articles are named here. 201.24.121.163 (talk) 19:16, 28 November 2007 (UTC)[reply]
