Way back when, I studied physics education. The beginner needs to be told what equations to use. The competent middleman knows how to find the equations that matter. But the expert... knows the physical principles and invents the equations to describe them.

They're beyond the math because they understand how the physics really works.

This has showed up when I, a retired rocket scientist, have tried to help my son with his high school physics homework. I can tell him how the system will behave and then we spend the rest of our time trying to identify the equations from his cheat sheet that will get that result.

So the curve from beginner to expert--pretty common. You have to use the rules until you reach the point where you understand enough to discard the rules.

Here's a dumb one we tell kids...bullies just need someone to be nice to them and they'll change.
