Inspired by the Copenhagen interpretation of quantum mechanics, the author introduces two axioms, one for measurement and the other for causality, to establish a new paradigm or world-description called "linguistic interpretation" or "quantum language". The paradigm casts a new light on the wellknown problems in quantum mechanics including Heisenberg's uncertainty principle, EPR-paradox, Bell's inequality, Schrödinger's cat (Wigner's friend), Wheeler's delayed choice experiment, and double-slit experiment. He shows that the paradigm works not only in quantum systems but also in classical systems, referring to regression analysis and Kalman filter in statistics and so on. He emphasizes the paradigm is a natural consequence in the history of philosophy, and shows how the famous problems in philosophy are solved such as Leibniz=Clarke correspondence "What is space-time ?", Zeno's paradox, and the principle of equal probability. He thus leads us to a conclusion that quantum language is a core concept of science.
Dr. Shiro Ishikawa, former associate professor at Keio University, graduated from Keio University in 1971. His research covers functional analysis, foundation of quantum mechanics, and philosophy of science.
There have been proposed many interpretations of quantum mechanics other than the so-called Copenhagen interpretation, for example, the many-worlds interpretation, Bohm's interpretation and statistical interpretation, etc.
Frankly speaking, the Copenhagen interpretation is the hardest one to understand. In other words, lack of clearness in the Copenhagen interpretation allows many other interpretations.
The author says that an appropriate paradigm has not been given yet that physicists can readily accept the Copenhagen interpretation.
The new paradigm he proposes is "quantum language " (= linguistic (Copenhagen
In this paradigm, the unclearness of the Copenhagen interpretation is complete ly resolved. I have understood the Copenhagen interpretation once and for all.
The author has succeeded because he studied classical systems and quantum systems from a unified viewpoint; the essence lying in the Copenhagen interpretation i s captured, and then formulated in two simple axioms.
It's uncertain whether the quantum language will be recognized as a standard theory in interpretation of quantum mechanics, but I can guarantee that this book serves as one of the best guides for the Copenhagen interpretation.
