Hello all.
I am currently reading 'The Elegant Universe' and I'm puzzled by one key thing that is really starting to 'niggle' me!
How can a one-dimensional string have multiple windings along a two-dimensional circular spatial dimension ("Garden Hose"). For this to be possible the string has to cross itself at one point (for two windings) or more, and surely you would need a third dimension to allow the string to pass over or under itself. With only two dimensions the string would have to pass through itself wouldn't it?
Sorry to ask such a 'lay' question but I'd really appreciate any clarification on this matter.
Many thanks,
CF
