   What is significant about the Yang-Mills gradient flow and
   renormalization, Ross?

settings.

Excuse me, I'm not a usual instructor in a post-graduate 
astronomical or cosmological setting.

I'm a usual instructor in unfettered modern mathematics.

Ah, for a mathematical physics:  those are the same thing.

That's part of a theoretical mathematical physics there 
with the conscientiously scientific setting and general 
survey and review of experimental data as in the high-energy 
physics.

What prompts this disjoint blabber?  It serves no purpose other than
to state: "Look at me.  Look at what I can do."

Big effing deal.  It's the signature of an effing loser.

Are you a physicist or a would-be psychologist?

Actually, the concept of gradient is fundamentally important
to physics.  For one thing, it defines the relation between
force and potential, and it is the idea of potential that
unifies nearly all physical laws.

But the gradient should already so familiar to physicists that
it would hardly need mentioning.

I suppose that Wormley has just discovered it.

What about the divergence and the curl?
