Bell's Inequalities |
Hi Everyone,
i would like to ask you something regarding the famous paper of Bell
reagrding the inequalities that
a hidden variable scheme must comply to in order to explain quantum
phenomena.
A friend of mine told me that recently someone published a paper claiming to
having found an error to Bells paper.
Is this true?

There are two kinds of books about quantum
mechanics. There are those in which we learn
about abstract concepts such as Hilbert spaces,
state vectors and density matrixes, but where the
author never addresses - or only pays lip-service
to - the question of what quantum mechanics
actually means. This is the approach often taken in
textbooks. The other, quite opposite, approach
focuses on the interpretative question - drawing all
kinds of conclusions and analogies, talking about
telepathy and other mysteries, and perhaps even
claiming that quantum mechanics transcends
Western philosophy.
Neither approach is very helpful when one wants
to understand what quantum mechanics really
means in a deep philosophical sense. Amir Aczel's
new book on entanglement - falling as it does into
neither category - avoids such pitfalls.

Physics at the University of Vienna reviews the
book in the May issue of Physics World; email

Unfortunately I can only direct to current research taking place, in
the understanding of.
Hope this helps.

"Bell and others showed that it was possible to distinguish between
quantum mechanics and these hidden-variable theories in a certain type
of experiment that measure a parameter known as S. Put simply, the
local theories predict that S will always be less than two, whereas
the quantum prediction is S = 2√2. When S is greater than two,
Bell's inequality is said to be violated."
