The epistemological primes of mathematics might be logic, set theory, category theory, model theory, graph theory, and a few others. Things that can't be reduced any further; their own whole ways of thinking.
These primes exist in everything. Doing drugs (the way I do them) involves knowledge of chemistry, thermodynamics, and cognitive psychology. Cooking also involves chemistry and thermodynamics, and the knowledge of "flavor profiles" (which cores does that come from?). Doing projects involves some kind of "how to work" prime.
"Physics" is not a prime, but kinematics probably is a prime.
It's hard to figure some of them out. Demographics feels prime, but is probably actually a few things mashed together. Same for metrology, photography, color theory, emergency rescue, asset management, rhetoric, etc.
Any thoughts?
