I've heard people around me say , they have learned more mathematics then they have in grad school just by reading this topic. Is this true , I know mathematics has a huge diverse background and specializing in many topics , well I don't know if it's even possible. So I'm asking the question , is thier a topic of mathematics that is very multi-specialized , where it encompasses most fields of mathematics , that you learn from? Would it be too advanced considering that thier is a sort of ladder analogy in mathematics , would you be able to learn it from a top-down sort of way? Would the person have to combine most or all fields? Is it like a fundamental theorem of mathematics? How specialized would it be?
