Andz Posted October 17, 2008 Share Posted October 17, 2008 A walk through mathematics! Nine chapters, two hours of maths, that take you gradually up to the fourth dimension. Mathematical vertigo guaranteed! www.dimensions-math.org Download, order a DVD or watch it online. Beautiful documentary entirely done in POV-RAY Quote Link to comment Share on other sites More sharing options...

Andz Posted October 19, 2008 Author Share Posted October 19, 2008 I'm glad you guys liked it. Anyone wants to discuss it? I'm up to chapter five. There is one thing I disagree. In chapter 2, the analogy of the lizards on paper only being able to recognize the sections of 3d shapes as squares and other polygons... Wouldn't they only be able to see these sections as lines, since they are all in one plane? Quote Link to comment Share on other sites More sharing options...

Wouldn't they only be able to see these sections as lines, since they are all in one plane? Nope, a 2D creature would still be able to "see" a full 2-dimensional figure, they'd just have to "walk around it". In the same way that we can't see all sides of a 3d figure all at once -- you need to walk around a building to see all its sides, and you need to turn a cube around in your hand to see all six sides (you'd have to live in 4 dimensions in order to perceive all aspects of the cube or the building all at once).

So I guess that they would have to identify a square just by how a line length changes while walking around it. Quote Link to comment Share on other sites More sharing options...
Tamis Posted October 19, 2008 Share Posted October 19, 2008 Well if we assume that they have 2 eyes you could say they see 2 dimensional depth. Quote Link to comment Share on other sites More sharing options...
