Simone Malacrida

Simone Malacrida (1977) Ha lavorato nel settore della ricerca (ottica e nanotecnologie) e, in seguito, in quello industriale-impiantistico, in particolare nel Power, nell'Oil&Gas e nelle infrastrutture. E' interessato a problematiche finanziarie ed energetiche. Ha pubblicato un primo ciclo di 21 libri principali (10 divulgativi e didattici e 11 romanzi) + 91 manuali didattici derivati. Un secondo ciclo, sempre di 21 libri, è in corso di elaborazione e sviluppo.

INTRODUCTION

This manual presents the theoretical framework of quantum physics.

Starting from the crisis of classical physics and going to study the solutions proposed at the beginning of the twentieth century, we will arrive at the exposure of quantum mechanics based on Schrodinger's equation.

The salient points of this revolution and the main differences with classical physics will be highlighted.

Indeterminism and the probabilistic vision will be the conceptual leap necessary for the rigorous definition of quantum mechanics.

Furthermore, quantum field theory as the final result of scientific investigation in quantum terms and its successful application given by quantum electrodynamics will be exhibited.

Finally, the questions still open in physics will be enunciated, such as the reconciliation with nuclear physics and with general relativity.

A separate chapter is devoted to notable applications of quantum mechanics, such as solid-state physics and semiconductor physics.

What is set out in this manual is only partially addressed at the university level, unless you choose a course of study in Physics.

To fully understand the above, especially from the third chapter onwards, knowledge of advanced mathematical analysis is required (differential equations and nabla algebra).

REQUIREMENTS FOR QUANTUM PHYSICS

The frame of reference at the beginning of the twentieth century

––––––––

In the second half of the 19th century, it became evident that classical physics itself had very large problems in explaining physical reality.

After two centuries of speculations and theories that had ranged from one end of scientific knowledge to the other, a point of no return had been reached in which these problems gradually became more and more in consequences.

There
