Talk:Ball (mathematics)/Comments

From Wikipedia, the free encyclopedia

This is an important topic, but the current treatment is back-to-front and unencyclopedic. The article should start with the ball in Euclidean 3-space, then move on to more general situations. Subtle issues such as whether the closure of an open ball is a closed ball should not dominate the article. Geometry guy 13:41, 13 May 2007 (UTC)
