For everything I do I want to see the big picture. How the pieces of puzzle come together. For math I have trouble picturing it. From my view Physics are well structured. If I were to picture Physics as a tree, I would imagine it having 6 big branches. 1. Classical Mechnics(kinematics,work,energy,rotation,etc) 2. Relativity(movement when approaching c, time dialation, the twins paradox,etc) 3. Thermodynamics(heat engines, the kinetical theory of gases, etc) 4. Electromagnetism(electrostatics, electrical current, induction, etc) 5. Optics(reflection, refraction of light, optical instruments, etc.) 6. Quantum Mechnics(the emission spectre, hydrogen model, etc.) the branches all have sub-branches and are ful of leaves also there are connections etc.This I can imagine. It helps me see how it all comes together when I study physics. But as Math goes my "tree" is not a tree is just a collection of different pieces of puzzle. There is Calculus, Geometry, Linear Algebra, Number Theroy, Algebra without being Linear, Statistics, Probability, Logic, Discrete Structures, all this stuff. I am wondering if you were to imagine math as a tree or a map of a country or whatever how would it look like?
