Crisis of Modern Statistical Physics vs Classical Deterministic Physics

This is a further comment on Leibniz Principle of Identity of Indiscernibles seemingly in conflict with the modern physics main-stream idea of electrons all alike like equal probabilities of outcomes of tossing a fair coin. 




That modern physics is in a state of deep crisis is acknowledged by leading physicists and also largely understood by the general public. Buzz words like dark energy, dark matter, inflation, Big Bang, multiversa, entanglementcollapse of the wave function,  particles and quarks, are floating around as elements of relativity theory on cosmological scales and quantum mechanics on atomic scales, both formed 100 years ago but still today harbouring toxic unresolved foundational problems, and on top of that being incompatible. A veritable mess. 

The root of the seemingly unresolvable problems of quantum mechanics can be traced back to the statistical interpretation of the multi-dimensional Schrödinger wave function as solution to the multi-dimensional Schrödinger equation serving as foundation. 

While classical physics is ontology about what reality is, modern physics is epistemology about what can be said. While classical physics is deterministic physics independent of human observer, modern physics in the form of quantum mechanics is statistical physics depending on human observers acting as mathematical statisticians in an insurance company busy computing insurance premiums. 

The departure from classical into modern physics was initiated by Boltzmann in the late 19th century seeking an ontological realistic explanation of the 2nd Law of Thermodynamics as the main unresolved problem of classical physics giving time a direction, which had to be resolved to save physics from disbelief. When Boltzmann understood that he could not reach this main goal of his scientific life, he made a Faustian deal in the form of an explanation based on statistical mechanics. This served to save the life of physics, but not Boltzmann's own life, and opened the door into the heaven of modern physics as quantum mechanics as statistical mechanics, which is now in a state of crisis. 

The step from deterministic physics to statistical physics, was taken in order to save classical physics from credibility collapse in front of the 2nd Law. The medication worked for the moment but the patient as classical physics died and so was replaced by modern physics, which however showed to be quite sick without any cure in sight still today. 

The first step in coming to grips with the crisis of modern physics, is to ask if it is impossible to explain the 2nd Law within classical deterministic physics? If not, then the step to statistics is not necessary and much trouble can be avoided. More precisely, it appears to be possible to replace statistics by a concept of finite precision physics as presented in Computational Thermodynamics and in popular form in The Clock and the Arrow with follow up into a realistic deterministic form of quantum mechanics as Real Quantum Mechanics

This means a return to deterministic physics with a new element of finite precision computational physics coming with resolutions of problems of classical physics making it possible to avoid paying the very high price of taking the drug of statistical physics. 

Real physics is what it is and is given to us for free. Statistical physics is man-made physics, which needs massive data and human interference. Real physics seeks to describe the World as it is, while modern physicists have the reduced goal of statistical prediction outcomes of man-made experiments. Schrödinger and Einstein could not accept physics as man-made statistics, but were cancelled. Maybe the present crisis can open to restart following their spirit?  

We may view real physics as a form of engineering or professional soccer game with basic questions: What is the basic mechanism/principle? How to improve it? On the other hand, a statistical physicist simply watches the game on TV and finds meaning in betting.
