Intrinsic roughly means inherent. In terms of stats, It can never be logically explained. But using wisdom, It can be understood. Such stats are felt - yes, FELT. For a physics model, the closest is a basis.
MY basis is usually realism. All that takes is education, and understanding the value in everything, using symbols.
Common sense is all you need to understand, applying REAL physics.
But.. need I say just how rare common sense is?
