This is one of the best five minute explanations (http://www.youtube.com/watch?v=aCQx9U6awFw&feature=player_) of 10 dimensions I've seen. It starts off with the familiar point -> Line explanation.

Might be fun to do a 10 dimensional mapping challenge, lol!

10!!!........You might want to look at my star chart threads and see the trouble I'm having with just three!

"Mapping" in 10 dimensions isn't cartography, it's math.

In math, what we do here are called charts. A map is a more generalized function.

Actually, a lot of cartography is done in more than three dimensions. Say, for example: latitude, longitude, altitude(:)), population density, mean temperature, annual precipitation, landuse, vegetation, slope, median income. I don't know exactly what that map would be for, but I have used all of those values in a map at some point. That's ten dimensions, right there.

My favorite method for 3-d starmapping was the one I first saw in Space Opera, x and y coordinates are shown by the position on the flat map surface with z denoted by a number superscripted to the point representing the star. This works well for discrete positions like stars, not as well for places on a continuous surface like the ground. Conversely, while I like the contour starmap idea as a novelty, I don't think it applies well. The space between stars is empty and doesn't logically have an elevation.

Please see the attached map for a 10th dimensional image:

Neon that's an amazing map! I saw it last year, in another lifetime!

Neon, I don't see a map, or is that the point? (Sorry have finally gotten to writing Christmas Cards and my mind isn't here (Not that it ever is))

If you do a map that catalogues say the changes of Empire in Europe from 0AD-2000AD have you made a 4D map, since you are computing the time factor. By this I would mean that you do it as say one of those Youtube videos where someone has just done loads of maps and just placed them order.

I believe that mathematically there are 11 dimensions.


10 doesn't quite work, but 11 does.

Mathematically, there are as many dimensions as you need (i.e., there are infinite dimensions available). Physically, the number of dimensions is a matter of considerable debate.
