    yes, i also looked at that site too.. but I dont understand it all.

    What did you mean by r^2 by the way ?

    and do rings have relevance to physics ??

    I didn't see any [itex] r^{2}[/itex]...:confused:

    Yes,they do.Theoretical physics uses abstract algebra a lot.

    Abstract Algebra

    Take a set, give it a few properties, that's what most of abstract algebra is about.

    A ring is just one of the structures that is studied in abstract/modern algebra.

    Start with groups, then it will get you to identify what a ring is a little better.

    How do you get started studying rings though ?

    I wanted to know what you meant by R^2 when you showed me the double integral..in the other homework question.

    Aaaaa,got it.You've studied cartesian (direct) product.It's the cartesian product of R with itself.

    You should have introductory abstract algebra in high-school.If not,then definitely in college,if u take a math major.
