Just wanted to point out that any contractible complex is simple homotopy equivalent to a point, and have edited the article to reflect this. — Preceding unsigned comment added by 192.76.7.198 (talk) 17:12, 18 January 2013 (UTC)

Intuitive description?[edit]

Is there any intuitive description or example of the concept of collapse that, at least in my opinion, would make the concept more accessible to non-mathematicians (like me) and thus would maybe enrich the article? --131.152.224.31 (talk) 09:38, 12 October 2011 (UTC)
