Making Sense of Quantum Mechanics??

Jean Bricmont starts his new book Making Sense of Quantum Mechanics with:
  • This book is both apparently ambitious and modest in its aims. Ambitious, as it attempts to achieve something that has been declared impossible by some of the greatest physicists since the 1920s: making sense of what quantum mechanics really means. 
  • But modest, because that goal was actually already attained many years ago in the work of Louis de Broglie, David Bohm, and John Bell. I will simply try to explain what they achieved.
  • It would seem that, given all the claims to the effect that such a theory is impossible, its mere existence should be a subject of considerable interest, but this is not the case. Although interest in the de Broglie–Bohm theory is probably increasing, it is still widely ignored or misrepresented, even by experts on foundations of quantum mechanics.
  • This book is written especially for all those students who feel that they have not understood the subject of quantum mechanics, not because they fail to master the mathematics or because they cannot do the exercises, but because they do not see what the theory means.
The message is that still 100 years after its conception quantum mechanics is not understood, neither by the greatest physicists nor by students. Any theory about physics with these qualities should have been dismissed long ago, but this is not the case and Bricmont gives us the reason:  
  • Since its beginnings in 1900, the quantum theory has led to the most spectacularly well confirmed predictions ever made in science (some experimental results agree with the theoretical predictions up to one part in a billion), and it underpins all modern electronics and telecommunications. 
  • It explains the stability of atoms and of stars, and lies at the foundation of the whole of particle physics, but also solid state physics, chemistry, and thus, in principle, biology. 
  • It is truly our most fundamental theory of the world. Yet, to quote the famous American physicist Richard Feynman that “nobody understands quantum mechanics”.
We read that no human being understands quantum theory, but nevertheless it is the most successful theory ever giving predictions which fit incredibly well with experiments.

We understand that this can only mean that quantum theory somehow has been given to humanity as  ready-made, not to understand but to use to make predictions for human needs, like a clock of a construction which cannot be understood given to us from Heaven, but yet always giving the exact time for our needs. The difference between religion and science is supposed to be that science can be understood by all educated or at least by some expert scientists, whereas religion is hidden to understanding for all people. The conclusion can only be that the quantum theory which Bricmont speaks about, is not science.

To get out of this hopeless mess from scientific point of view, because science means to understand, it is necessary to go to the root of the trouble, which is to insist that quantum mechanics as atom physics must be based on a (i) linear (ii) multi-dimensional wave equation named Schrödinger's equation. This is an equation which by (i) allows unphysical superposition of states and which by (ii) cannot be solved for many electrons/atoms and thus can make real predictions only in very simple cases. 
But there may be a way out of the hopeless mess, and that is to start from a different form of Schrödinger's equation without (i) and (ii). This is explored in Many-Minds Quantum Mechanics.
Why not take a look, if you like Feynman and everybody else, do not understand quantum mechanics.

The key step is to replace an uncomputable linear multi-dimensional unphysical form of Schrödinger's equation with a computable system in 3d physical space, and in this way eliminate the unfortunate unphysical aspects which has driven modern physics into meaningless scholastics of mystery and fantasy.
