WebbEigenvalue equation in polar coordinates. The classical definition of the angular momentum vector is. L = r × p (3.1) which depends on the choice of the point of origin where r =r=0 r =r=0. With the definition of the position and the momentum operators we obtain the angular momentum operator as. ˆL = − iℏ(r × ∇) (3.2) WebbIn the first place we discuss the problem of interpretation and analyze the importance of such an objective account in physics. In this context we present the problems which …

The well-known Heisenberg-Robertson uncertainty relation presents the constraints on the spread of measurement outcomes caused by the non-commutability of a pair of observables.

(Schr odinger, ‘The present situation in quantum mechanics’, x5) One point of this example is that we can’t just comfortably isolate quantum behavior in the realm of the very small, since we could, with su cient ingenuity, rig up connections between events in this realm and observable events, like the death of a cat.
