What do you mean with dimension?
Since I have read there is no math involved (which I have difficulties to understand), what is it that is called four or five dimensional?
Why not 31/2d or 31/3d?
Do we speak of topological, metric, verctor spaces?
I didn´t get it, yesterday the post on 5d was closed in the exening to answer.
How can someone invent the term 4d or 5d if it has nothing to do with math? I find that strange misleading to those who have math understanding...
So please, what is 4d and what 5d beyond any math?
