The Vienna Circle and its Philosophy

The next Naturwissenschaftscafé will take place on Friday 21st April at 6pm at Strudlhofgasse 4. The topic will be the Vienna Circle and its philosophy.

Please read into to material provided below to prepare for the meeting.

Level 1
To get an overview of the Vienna Circle just have a look at the Wikipedia article:

Level 2
For a bit more background there are some sources I can suggest you to look into:

Interview of A.J. Ayer on Logical Positivism and its Legacy :

Prof. Christian Damböck, who also held a talk on the Symposium, wrote a book about the Vienna Circle (Ausgewählte Texte des wiener Kreis). He published a postface which I strongly suggest you to read (unfortunately in German): Nachwort zu Ausgewählte texte des wiener Kreis:

Level 3
For those of you, that really want to spend more time learning about the Vienna Circle, read the following:

Book (which I will bring with me to the NWC): Sie nannten sich der Wiener Kreis, exaktes denken am rande des Untergangs by Karl Sigmund

and the article of Stanford Encyclopedia of Philosophy:

How to choose the right Quantum Interpretation: Macrorealism, Contextuality and Decoherence

The next NWC will be held upcoming Friday 7th April at 6pm at the faculty of physics in Strudlhofgasse 4.

First, I would like you to revisit the materials from last time about Bells Inequality and local realism. Also Flavio already included nice material about Leggett-Garg Inequalities and macrorealism.

Second, here are my resources:

Level 1: I will cover basically the Legget-Garg and Kochen-Specker Theorems and how they could be experimentally tested to rule out certain QM Interpretations similar to Bell’s Inequality and local realism. A good starting point:

Level 2: Kofler and Bruckner have written a nice comparison between Bell and L-G, also thinking about experiments that violate macrorealism:
And (my all-time favorite) Stanford Encyclopedia of Philosophy has a review over Kochen-Specker and it’s implications:

Level Experimental Metaphysics:
Well, in one meeting we probably won’t have time to cover more, but for the sake of completeness on experimental tests of quantum foundations, one has to add the current notion of decoherence as most promising solution to the measurement problem. Also this gives an idea why the many-worlds interpretation gains momentum right now.

Here is a recent overview of how decoherence relates to different interpretations:

And the legendary lecture of Harvard Professor Sidney Coleman “Quantum Mechanics in your Face”:
