#1 I always thought the fourth dimension was time.

curious!

#3 My degrees were in physics, so I am probably not qualified to appreciate this. But my initial impression is that it is a bad joke. In mathematics you can work in n dimensions. However, in the real world in which we live, the observer centered world of physics, the human observer can perceive 3 spatial dimensions and the flow of the fourth, time. The other dimensions "commonly" accepted by physicists are not capable of being perceived through direct observation, but can be demonstrated through elaborate experiments.

I guess I can understand the idea of the 3 dimensional shadow, but the thing as a mental portal to the fourth dimension, a teaching tool, and a research object bringing together many branches of mathematics and physics connected to the structure of symmetry is the purest, most refined form of grantsmanship I've seen in awhile. Somebody got hosed.

#5 The other dimensions "commonly" accepted by physicists are not capable of being perceived through direct observation, but can be demonstrated through elaborate experiments.

The only thing that we can see would be the intersection of the 4-dimensional object with our 3 dimensions. The analogy would be an intersection of a hollow sphere (a 3-d object) with a piece of paper (a 2-d object). To a person stuck in the 2-d world, all he sees is the intersection, which in this case would be the outline of a circle.

#6 Oops...that's assuming the piece of paper cuts thru the sphere somewhere in the middle. If the piece of paper is tangential to the sphere, then the only thing the 2-d person sees, is a point.
