In contrast to curve fitting, the Heisenberg uncertainty relations tell us that the QM variances of position and momentum are not controllable and reducible without limit. Never ...

CALCULUS OF FUNCTIONALS
... In classical mechanics one has interest in functions x(t) of a single variable, while in field theory one’s interest shifts to functions ϕ(t, x) of several variables, but the ordinary calculus of functions of several variables would appear to be as adequate to the mathematical needs of the latter sub ...

... This formula also is correct only within the second power of h; in order to derive it one has to perform again some partial integrations with respect to the x. Eqs. (28), (29), (30) have a strict quantum mechanical meaning and it should be possible to derive them also from (4). One sees that the kin ...
