I know that the sphere doesn't embed in R^2, I wouldn't necessarily know hoe to prove it, though... The invariance of dimension theorem says that R^m=R^n iff m=n, right? I am not sure how to use it to prove what i want..could you give me more details, please?

Does the unit circle S^1, embed into R^1 ?
