We started out with two unphysical quantities and their unphysicalness sort of cancelled each other out. • Blechman Says, Before you label this as ridiculous, realize that QED has used renormalization all the time, and its results have been tested to as many as fourteen decimal places.

Uncertainty Relations for Quantum Mechanical Observables
... 3 Heisenbergs noise-disturbance uncertainty Often the position-momentum uncertainty (2) is interpreted in the following setup: The observable A of the particle in the state ψ is measured with error η ψ (A). By this measurement noise ²ψ (B ) is inflicted on the state ψ. This noise is added to the me ...

... system A. Since the dynamics of system B is completely ignored, it is impossible to prove that energy is conserved. To avoid this problem, it is assumed that whatever energy is lost or gained by A is gained or lost by B but in such a way that these changes in B do not affect the time evolution of A. ...
