A duck walks into a bar. Animal control is promptly called and the duck is released into a near by park.

comment Why quantum mechanics?
Can you, for a concrete simple example in quantum mechanics, follow this procedure (take classical geometry, choose circle group bundle with connection, write down the expression which amounts to the integration "in the $i$-direction") and express the observables $\langle H\rangle, \langle P\rangle, \dots$ in therms of this. Is there the harmonic oscillator, starting from the classical Hamiltonian, worked out with emphasis on exactly those bundles?

@jinawee: Yeah, I know, I can't quite remember what it was - probably just a screencap of that second section on Wikipedia I speak about.

comment How can we say that a wave function follows schrodinger equation using operators?
If by energy operator you mean that it's a function value of $H$, i.e. $Â=F(H)$, for example $Â:=4H+H^4$, then $Â$ and $H$ have the same eigenfunctions. (I'm pretty sure about this, certainly in the common cases, but not in general. Look up the spectral theorem. Maybe there are pathological functional analysis scenarios I can't think of right now, it happens sometimes. You know, such that if $F$ is ill-behaved, the domain of $H$ and $F(H)$ is different etc.)
