What's with all the inconsistent theories for everything? It makes physical science incredibly annoying to learn.

>Chemistry
->Organic
->Inorganic
->Physical
->Nuclear

>Physics
->Statistical Physics
->Thermodynamics
->Atomic Physics
->Nuclear Physics
->Quantum Physics
->QED
->QFT
->QCD,

Etc etc etc

Just fucking decide what's actually important instead of creating millions of random branches that waste everyones time and causing tons of confusion.
