The Secrets of Quantum Physics part 1 Einsteins Nightmare

A few days ago I watched a brilliant BBC science documentary posted on youtube called '

The Secrets of Quantum Physics 1of2 Einsteins Nightmare'.  It was about quantum physics and presented by the Scottish physicist Jim Al-khalili.

It gave a very good primer on the historical background of quantum physics, especially the photostatic effect, the ultra-violet catastrophe and the wave particle duality of light.  This programme is the Beeb at its best. For a difficult subject, Al-khalili's presentation was very clear and easy to follow.  It even looked into the debate and doubt that Einstein had about quantum physics called the Einstein-Podolsky-Rosen(EPR) paradox and how it was eventually resolved in the 1960's and 1970's by experiments carried out to test Bell's theorem.
