Document Summary
The schr dinger wave equation formulation of quantum mechanics. Notes: most of the material in this chapter is taken from thornton and rex, chapter 6. There are several formalisms available to the quantum physicists. As stated in the previous chapter, the two original and independent formulations were those of. Schr dinger"s version of quantum mechanics is based on the evolution of a wave function characterizing the system, a notion previously introduced in chapter 4, as dictated by the. This is the approach we will take here. It is interesting to note, however, that richard feynman (1918-1988) introduced in the late 1940"s another very successful approach to quantum mechanics based on so-called path integrals or sum over histories. Whatever the case, all of these versions of quantum mechanics are equivalent and make the same predictions for the outcome of measurements. The schr dinger wave equation, which serves this purpose, is not something that can be rigorously derived from first principles.
