Перечитал классическую статью Джона Белла (1980): Bertlmann's socks and the nature of reality (https://hal.science/file/index/docid/220688/filename/ajp-jphyscol198142C202.pdf) -- превосходный текст про парадокс Эйнштейна-Подольского-Розена, неравенства Белла, и их экспериментальную проверку. Статья написана как научно-популярная, но все объясняется по-настоящему и изложено предельно четко.
The philosopher in the street, who has not suffered a course in quantum mechanics, is quite unimpressed by Einstein-Podolsky-Rosen correlations. He can point to many examples of similar correlations in everyday life. The case of Bertlmann's socks is often cited. Dr. Bertlmann likes to wear two socks of different colours. Which colour he will have on a given foot on a given day is quite unpredictable. But when you see (Fig. 1) that the first sock is pink you can be already sure that the second sock will not be pink. Observation of the first, and experience of Bertlmann, gives immediate information about the second. There is no accounting for tastes, but apart from that here is no mystery here. And is not the EPR business just the same?
Чего я не знал, так это что Dr. Bertlmann -- это не вымышленный персонаж, а вполне настоящий, друг и коллега Белла, профессор Венского университета https://en.wikipedia.org/wiki/Reinhold_Bertlmann. У него есть подробные воспоминания о Белле: https://arxiv.org/abs/1605.08081.
At the end of summer 1980, I returned for some time to my home institute in Vienna to continue our collaboration on the gluon condensate potential from there. At that time, there was no internet, and it was a common practice to send preprints (typed manuscripts) of the work, prior to publication, to all main physics institutions in the world. Also we in Vienna had such a preprint shelf where each week the new incoming preprints were exhibited. One day, on the 15th of September, I was sitting in the Institute’s computer room, handling my computer cards, when my colleague Gerhard Ecker, who was in charge of receiving the preprints, rushed in waving a preprint in his hands (see Fig. 11). He shouted, “Reinhold look - now you’re famous !” I hardly could believe my eyes as I read and reread the title of a paper by John S. Bell [121]: “Bertlmann’s socks and the nature of reality”.
I was totally excited. Reading the first page my heart stood still: [...]
Seeing the cartoon John has sketched by himself (see Fig. 12), showing me with my odd socks, nearly knocked me down. All this came so unexpectedly - I had not the slightest idea that John had noticed my habits of wearing socks of different colours, a habit I cultivated since my early student days, my special ‘generation-68’ protest.
