Corrected. Does it now make sense?

comment High dimensional vector space references
@Taladris, it is obvious that the proposition about $S^n$ is only true for $n \gg 4$ and is false for low dimensions such as $n = 1, 2, 3, 4$. A regular linear algebra or vector space introduction will not develop this.

@Micah, the proposition about $S^n$ spheres is actually true only if the embedding vector space has an Euclidean norm.
