The most foundational science is pretty obvious after all.

We all know that apples fall from trees and that banging 2 rocks together makes sparks.

I think maybe “foundation” was the wrong word.

Maybe origins?

My point was that the basic ideas that have been studied and refined over centuries were simple.
