That's correct. -
Pplanck999 replied to the thread Graduate Deviations from classical action and D’alembert's principle, why is D’alembert's principle not applicable to QM?.Thanks for your explanation. Then, a non stationary path cant create weird phenomena in gr, like a non inertial geodesic. Anything...

Pplanck999 replied to the thread Graduate Deviations from classical action and D’alembert's principle, why is D’alembert's principle not applicable to QM?.I misunderstood one thing in path integral formulation I guess. Meaning of different phases cancel out at macroscopic level isn’t all...

Pplanck999 replied to the thread Graduate Deviations from classical action and D’alembert's principle, why is D’alembert's principle not applicable to QM?.And, we interpret non stationary phases physically in an intuitive manner. What would be the meaning of non dlamabertian paths? And in a...

Pplanck999 replied to the thread Graduate Deviations from classical action and D’alembert's principle, why is D’alembert's principle not applicable to QM?.Because action principle does apply to r and q. And it gives the same results with action principle. Also, its derivation doesnt...

Pplanck999 posted the thread Graduate Deviations from classical action and D’alembert's principle, why is D’alembert's principle not applicable to QM? in Quantum Physics.We can derive action principle from dAlemberts principle. Does deviations from classical paths violate the d’alemberts principle? Like...

Pplanck999 posted the thread Graduate My questions about QFT and the standard model in Quantum Physics.First of all, I guess classifying particles as excitations of fields stem from the fact that fields can be decomposed into plane waves...
