The Introduction provides the reader with a more detailed overview over
the goal and the approach of this book, including the new features against previous
publications. Special attention is paid to the importance of notions and to the
relationship between classical and quantum mechanics. Another key topic is
Schrödinger’s forgotten 1926 requirements to any path from classical to quantum
mechanics. The approach of this book fulfills all four of them, and this will help to
overcome several difficulties of interpretation. Mittelstaedt’s “reconstruction” of
quantum mechanics is discussed in some detail, because there are several similarities
to that approach. The Introduction concludes with the key lines along which this book
is organized.
Keywords: Axiomatic, Classical mechanics, Mittelstaedt, Quantization, Quantum
mechanics, Reconstruction, Relationship between classical mechanics and quantum
mechanics, Schrödinger, State, Stationary state.
