Is there any Book/Book Series/Website which illustrate advanced mathematics but in concise and basic form. I just want to be familiar with the literature and I don't want a deep exploration of the topics. What I want is a near complete survey on different topics of math, What is important for me is the basic ideas and the connections between different parts of mathematics. For example if it talks about abstract algebra, then a quick survey of the concepts of group, ring,... and how these are connected to other topics...I just want to get a obscure grasp but pretty comprehensive topics.
BTW, I know there might not any reference but there might be a series of books. Or different book for different topics e.g. one of Geometric Algebra one for stochastic processing and so on. You know, I just want to get a good grasp of literature as a whole.
p.s. currently I'm interested in functional analysis, harmonic analysis, number thoery and operator theory.
