Working on an art project using Feynman diagrams ... I'm curious if there are any that you consider to be particularly relevant to everyday human experience or particularly beautiful (according to any criteria you wish). Thanks!

Here's an example (and please feel free to point out if I've got this wrong).

When we step out into a beautiful sunny day, we can thank the weak interaction, which makes possible the fusion taking place in our star. A critical part of that process is electron capture, as laid out in this Feynman diagram:

Neat! I wonder how he picked which diagrams to use. Found this: "Of particular note is the diagram on the rear of the van ... this diagram shows two muon neutrinos exchanging a particle that Feynman could only conjecture at the time. Years later, such a particle was proven to exist and called a Z boson."
 
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
