When investigating theories at the tiniest conceivable scales in Nature， almost all researchers today revert to the quantum language， accepting the verdict that we shall nickname \"the Copenhagen doctrine\" that the only way to describe what is going on will always involve states in Hilbert space， controlled by operator equations. Returning to classical， that is， non quantum mechanical， descriptions will be forever impossible， unless one accepts some extremely contrived theoretical contraptions that may or may not reproduce the quantum mechanical phenomena observed in experiments.
　　Dissatisfied， this author investigated how one can look at things differently. This book is an overview of older material， but also contains many new observations and calculations. Quantum mechanics is looked upon as a tool， not as a theory. Examples are displayed of models that are classical in essence， but can be analysed by the use of quantum techniques， and we argue that even the Standard Model， together with gravitational interactions， might be viewed as a quantum mechanical approach to analyse a system that could be classical at its core. We explain how such thoughts can conceivably be reconciled with Bell's theorem， and how the usual objections voiced against the notion of 'superdeterminism' can be overcome， at least in principle. Our proposal would eradicate the collapse problem and the measurement problem. Even the existence of an \"arrow of time\" can perhaps be explained in a more elegant way than usual.
