[edit] 2d=3d

its said that a 3d object is said just to be several 2d ojects stacked ontop off oneanother to create thickness butt how can several 2d planes wth a thickness of 0 add up to be somthing that had thickness and thuss create a 3d object?

Because you're stacking together an uncountably infinite number of 2D objects. Infinity times 0 is not necessarily 0 (technically, it's undefined). Crispy (talk) 00:43, 26 March 2009 (UTC)

[edit] 3d networks as spaces

This article may be improved by adding a mention of Graphs (ie networks of nodes or connectivity information) that have dimension of 3 through Dimensional_analysis. This type of structure is an alternative to the axis-based way of thinking about the dimensionality of space in the universe. See also Fractal dimension on networks.

The article would benefit from a link to Dimensional analysis, and but I don't think this application of dimensional analysis belongs in the article. --Una Smith (talk) 01:39, 2 July 2009 (UTC)
