You Know the Words, Not the Music & mostly not even the words.

If I ask you “What is Stokes’ Theorem?” you’ll  give me the definition like a robot — curl of a vector field, line integral equals surface integral, blah blah. But the second I ask you “What the hell does Stokes’ Theorem actually mean in the real world? How is it there, physically?” — Then there will be no answers. That's gonna cost later.
