Talk:Flatness

From Wikipedia, the free encyclopedia

I think mathematical part of this article is completely useless and should be removed

Maths section seems fine to me, but the last link (http://journals.iranscience.net:800/www.newscientist.com/www.newscientist.com/lastword/article.jsp@id=lw801) gives me connection refused. 192.171.162.101 15:27, 9 Mar 2005 (UTC)

I am against the merger of Flatness#Flatness in mechanical engineering into Thicknesser, the articles have very little to do with each other. JMiall 19:07, 3 May 2006 (UTC)

[edit] Yet another meaning of flatness

I added a section on flatness in dynamical systems theory. Unfortunately, no one has created an article on this interesting property. Anyone out there who can do it? --JanHRichter 20:25, 15 October 2006 (UTC)

[edit] liquid flatness

The "flatness" of a liquid surface is not dependent on the local curvature of the earth's surface, but upon the distance of the surface from the center of gravity with additional small perturbations due to the earth's rotation, position of the moon, etc. Likewise, the curvature of the earth (barring any local deformations) is dependent upon its distance from the center of gravity (with similar perturbative influences). This should be made clear in the article. The local curvature of the earth and the curvature of a liquid surface are similar because of a similar underlying cause - one is NOT caused by the other. —Preceding unsigned comment added by 65.202.227.61 (talk) 18:25, 26 February 2009 (UTC)
