... as a wave function as described by Schrodinger’s equations. The evolution of the wave function is deterministic and everything we measure (velocity, position, energy etc) depends on its wave function. However, at the point of measurement, the wave function collapses and the outcome is probabilistic. ...

Yangian Symmetry in Yang
... Understanding Yang-Mills theories is the great challenge for theoretical physics. The Yang-Mills theory with the best chance of being integrable is the maximally supersymmetric one, with a set of four fermions and six scalars for each gauge boson. We don’t yet know what it means for such a theory to ...

Bell's theorem

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:
