Here we will overview the technique be starting on classical dynamics, in par-ticular, the random walk problem before we discuss the quantum case by looking at a particle in a potential, and

1 Lecture 3: Operators in Quantum Mechanics
phys.spbu.ru1 Lecture 3: Operators in Quantum Mechanics 1.1 Basic notions of operator algebra. In the previous lectures we have met operators: ... H^ = p^2 2m +V^(x^) where p^2=2mis the K.E. operator and V^ is the P.E. operator. This example shows that we can add operators to get a new operator. So one may ask what other algebraic operations one can
