- 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.
- 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”.
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.
