Riemann几何是具有二次型度量的微分流形, an another perfect world assumption, but as a "gauge model" it is ok?
in that sense:
QFT: everybody is a smart man, no money to make;
conventional thermodynamic systems: everybody is a stupid man, no money to make;
in between, kind of where we are now:
"non sr macro qm": a lot of money to be made and lost between stupid neuron/离子 "heat" driven brain mass and "s-cat" based groups like wh, ws, sv, and tg?
