I have been following along the problem on SO(32) st. in Zwiebach's "A first course in String theory" and my question concerns this problem. I have no problem with the mathematics of SO(32), at least not at the simple level Zwiebach discusses it, rather the "why" behind a particular concept of SO(32).
If one bosonic string (D-1=25) and one super string (D=10-1) are combined, only 10 spatatial dimensions match and 16 remain of the bosonic string. So one wrapes the extra 16 dimensions into 32 two dimensional planes*.
Why, if one is trying to get rid of the extra 16, would one create 32 wraped up dimensions?If one were to wrap the dimensions up wouldn't the result be 8 two dimensional planes?
*I doubt this word is suiting, as with some others( e.g. "wraped")
Thankyou for all help
