I was wondering if anyone can recommend a good abstract algebra book? It’s something I have been wanting to learn a bit of. I am a geophysicist so I have pretty strong linear algebra, calculus and general numerical

Methods background, but have never taken set theory or real/imaginary analysis.

When I took an abstract algebra course in college, the text we used was A Book of Abstract Algebra, 2nd ed by Charles C. Pinter. Decent book as I recall.
