answer:I think, given that it’s a math class, you should be talking about how difficult it is to see three dimensional objects in a two dimensional perspective. It’s valuable to see that because it helps people understand that things in higher dimensions than three may be real even though we have trouble conceptional them. You know, one of the theories kicking around about the nature of the universe is that it is actually 17 dimensions, and that we live in a three dimensional part of it, but can occasionally see the outlines of higher dimensional objects.
