Luke, do you agree there is no such thing as a non-mathy understanding of graph theory?

I think Vladimir is saying physics is like that. Because when you take away the math, you are no longer able to explain what is really going on.

Can such an explanation really be called "great"?

Is that the right link? Because the that post, "Guessing the Teacher's Password", gives a purely verbal description of a object getting heated up and turned around. Explicit mathematics doesn't come into it either on the part of the successful student or the reader of the document. Basically it provides yet another example which reduces Vladimir's claims to absurdity.

When I was young, I read popular physics books such as Richard Feynman's QED: The Strange Theory of Light and Matter. I knew that light was waves, sound was waves, matter was waves. I took pride in my scientific literacy, when I was nine years old.

When I was older, and I began to read the Feynman Lectures on Physics, I ran across a gem called "the wave equation". I could follow the equation's derivation, but, looking back, I couldn't see its truth at a glance. So I thought about the wave equation for three days, on and off, until I saw that it was embarrassingly obvious. And when I finally understood, I realized that the whole time I had accepted the honest assurance of physicists that light was waves, sound was waves, matter was waves, I had not had the vaguest idea of what the word "wave" meant to a physicist.
