I'm currently (fall 2013) a third year graduate student at the University of Pennsylvania. My thesis, still in its infancy, concerns maps from fundamental groups of complete curves over fields of positive characteristic into linear groups.

comment Ring theory : Completely lost and overwhelmed
@Surya The answer is, you'll need to keep reading. And yes, you should be wondering why people care about ideals and what problems they solve! Keep reading with exactly those questions in mind! And as you read, also have those examples in mind. Pretty soon you'll get to quotients, and see some more familiar and/or interesting things like modular arithmetic.

Examples, examples, examples. If you have a theorem that feels meaningless and abstract, see how it applies to an example you already understand. What if you remove some assumptions to the theorem? Can you find a counterexample?
