During this lecture a brief advent is given into the idea of the Feynman direction critical in quantum mechanics. the final formula in Riemann areas might be given in response to the Weyl- ordering prescription, respectively product ordering prescription, within the quantum Hamiltonian. additionally, the idea of space-time alterations and separation of variables can be defined. As basic examples I speak about the standard harmonic oscillator, the radial harmonic oscillator, and the Coulomb strength.
