... The Schrödinger equation (time-independent version) • Is a fundamental law of nature: It can not be proved, but we know it works. Newton's second law of motion (F=m a) is another example of a law of nature. • Applies at the microscopic scale: electrons, atoms, molecules, etc. • What information can ...

... colloids are increasingly chosen as model condensed matter systems because of their relative accessibility and versatility. In this talk, I will describe our recent work on optical micromanipulation and colloidal electrostatics. In particular, I will show how Einstein’s formulation of the fluctuatio ...

... If one calls a commutant of a set A the special set of bounded operators on L(H) which commute with all elements in A, then this second condition implies that the commutant of the commutant of A is again the set A. On the other hand, a von Neumann algebra A inherits a unital subalgebra from L(H), an ...

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:
