A Model of Time

Light signals are used to gauge clocks and the framework of relativity is thus derived. In the EPR (Einstein-Po ...

Inequalities for means of chords, with application to isoperimetric

Another inspiration is the isoperimetric problem for the Dirichlet Laplacian on a closed loop-shaped tube, where it can be proved that the ground state is uniquely maximized by a circular annulus [6]. By a natural analogy one expects a si ...

Introduction to the general boundary formulation of quantum theory
... In a fundamental quantum theory a state is a priori a state of the universe. But, we cannot hope to be able to describe the universe in all its details. We need to be able to describe physics locally. In quantum field theory this is achieved dynamically, using the background metric. Causality and cl ...

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:
