Sean at Cosmic Variance wonders why we can’t visualize more than three dimensions. I find it both hard to imagine how you could visualize four dimensions and hard to imagine what biological feature of our brains prevents us from doing so.

I have thought about this problem; To me it seems with effort we should be able to visualize in 4-d but the result is kind of spooky. Since we can depict 3-dobjects on a 2-d piece of paper we should be able to build a 3-d sculpture that depicts 4-d objects. We need to do the math and get the angles correct; the next problem seems to be that since we live in 3-space, objects that will not block or cross others in 4 space will do so in 3-space. Now the whole thing about only being able to see sections of a 4-d object seems to me only to apply if somehow one somehow introduced a 4-d object into 3-space. If one is just visualizing one should be free of this problem. Does this make sense; I have been trying to think of a art project that would build stuff that be 3-space sculptures of 4-space objects. If thios is interesting please reply. We do all sorts of things not designed into us by nature or whatever. Thanks and Have Fun, Sends Steve
