We require the scalar product to be linear such that |ψi = a1 |ψ1 i + a2 |ψ2 i implies hφ|ψi = a1 hφ|ψ1 i + a2 hφ|ψ2 i. We see that hψ|φi = a∗1 hψ1 |φi + a∗2 hψ2 |φi and so hψ| = a∗1 hψ1 | + a∗2 hψ2 |. We introduce l ...

Lecture 11 Identical particles
... In classical mechanics, particles are always distinguishable – at least formally, “trajectories” through phase space can be traced. In quantum mechanics, particles can be identical and indistinguishable, e.g. electrons in an atom or a metal. The intrinsic uncertainty in position and momentum therefo ...

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:
