50 years of Bell's theorem: watch Zeilinger's talk

Well, I don't really count Bell's theorem among the top discoveries of physics but it was still a result that showed the irreversibility of the quantum revolution more clearly than previous arguments.

Anton Zeilinger is a wise guy (not to mention that he is the president of the Austrian Academy of Sciences) and he is just giving a talk at CERN that you may watch live:

From John Bell at CERN to Quantum Communication and Quantum Computation (video)
The screen under the link above has two parts, one with the speaker and one with the transparencies.

You are invited to watch. The talk starts in 5 minutes, at 16:30 Prague Summer Time.

About 30 readers will open TRF in these five minutes so someone who is interested may still watch the talk from the beginning.

At the beginning, Director Heuer has pointed out that he was not interesting so there was no reason to take photos. He exchanged a few sentences with Zeilinger that were encrypted in German. I have mostly decoded the secret code. Concerning this code, Zeilinger pointed out that the word "entanglement" isn't too good so he proposed to replace it by a more accurate and simpler one, die Quantenverschränkung. To make things truly simple, he means what is called, in plain German, die Spukhaftfernwirkungquantenmechanischverschränkung. It really sounds like music to my ears.

The EPR paper from 1935 only had a few (good) citations for decades. It wouldn't have been enough for the authors to get a permanent position, no doubt about it.

Zeilinger's point is that you shouldn't use such translators for such a nice word because the translation isn't lossless.

Looks like teh czechs and the Slovaks are 'together again' for the first time since 1993:

"The problem is that if sanctions are escalated now, there will be a reaction from Russia and we are not able to estimate at this point what impact the next wave of sanctions by Russia against EU countries will have," Prime Minister Bohuslav Sobotka said on Tuesday. "If we are entangled in an extensive and lengthy war [of sanctions] between the EU and Russia, both Europe and Russia will pay dearly for it,"Sobotka added.

Sobotka sounds a lot like Motl on this.
