... In the above construction, it is observed that the number of zero points of function η in Eq. (4) is equal to that of function Kummer U[−µ/(2ω), 1/2, ω (x − y)2 /2], which strongly depends on ω and the ratio µ/ω. We assume the number of zero points in η along line y = −x is l.

This choice satisfies Rule 1 of the previous section and, trivially, also Rule 2: if λ = 0 there is no dynamics at all since H = 0 and, as a consequence, [H, n̂1 ] = [H, n̂2 ] = 0. Concerning Rule 3, it is an easy exercise to check that I(t) := n̂1 ...

Bell's theorem
.svg?width=300)
Bell's theorem is a ‘no-go theorem’ that draws an important distinction between quantum mechanics (QM) and the world as described by classical mechanics. This theorem is named after John Stewart Bell.In its simplest form, Bell's theorem states:Cornell solid-state physicist David Mermin has described the appraisals of the importance of Bell's theorem in the physics community as ranging from ""indifference"" to ""wild extravagance"". Lawrence Berkeley particle physicist Henry Stapp declared: ""Bell's theorem is the most profound discovery of science.""Bell's theorem rules out local hidden variables as a viable explanation of quantum mechanics (though it still leaves the door open for non-local hidden variables). Bell concluded:Bell summarized one of the least popular ways to address the theorem, superdeterminism, in a 1985 BBC Radio interview:
