Re: Math Books

Does anybody know of a good book for learning about algebraic varieties at a last year undergraduate/graduate level?
I'm trying to learn some of the work of Grothendieck but I don't really know where to start.

free rings and ring coproducts

Hi forum people,
So does anybody know how to construct the free ring on a set or whether there is a canonical coproduct in the category of rings?
I've seen both mentioned in a couple places but I haven't been able to find the actual construction.
I don't really know enough to figure it out.

Re: "Therefore" versus "implies"

I like to use different ones as like parenthesis
so to say a implies (b implies c)
i would say a, therefore b implies c
or something to that effect

Re: Wrong on the Internet II: Norman J. Wildberger

He seemed all right until around 21:00 where he starts talking about how analysis is really a conspiracy(his word not mine).
"Real numbers as usually presented are, in fact, a fraud. They don't actually make sense."
