Vorticity tensor

edit

Currently, there is no article, AFAICFind, on vorticity tensor (as applied to fluid dynamics), although there is one on vorticity; I assume that there will be in the future. I think it better, however, to use the link vorticity tensor (relativity) for the one that refers to the congruence (it should avoid a future problem). ---Mpatel (talk) 13:08, 12 October 2005 (UTC)Reply

That is correct. This is one of the strange gaps in WP coverage. ---CH 00:49, 1 July 2006 (UTC)Reply

Students beware

edit

I created the original version of this article and had been monitoring it for bad edits, but I am leaving the WP and am now abandoning this article to its fate.

Just wanted to provide notice that I am only responsible (in part) for the last version I edited; see User:Hillman/Archive. I emphatically do not vouch for anything you might see in more recent versions, although I hope for the best.

Good luck in your search for information, regardless!---CH 00:49, 1 July 2006 (UTC)Reply

Unclear lede

What the heck does this mean:

This means that the angular isotropic coordinates do not faithfully represent distances within the nested spheres

Faithfully for who? With respect to what? A freely falling observer? Something else? Also this:

Compare Schwarschild coordinates, where the radial coordinate does have its natural interpretation in terms of the nested spheres.

What is a "natural interpretation"??? 67.198.37.16 (talk) 06:54, 21 February 2016 (UTC)Reply
