Old Quantum Theory and Early Quantum Mechanics

This book provides a historical presentation of Old Quantum Theory and

early Quantum Mechanics integrated with comments and examples that help

contextualize and understand the physics discussed.

It consists in a detailed analysis of the usual topics that have most

contributed to the birth and the development of Quantum Mechanics

(black-body spectrum, atomic models, EPR paradox, etc.), but also dealing

with ideas, concepts and results that are not usually treated (vortex

atoms, discussion on the meaning of the term “electron”, non-quantum

models of the Compton effect, etc.). The time span taken into

consideration goes mainly from the 1880s to the 1940s; but some brief

notes on more recent results are also presented in the appendixes.

The work is based on nearly 800 original documents – books, papers, letters,

newspapers – whose content is not only partially reported, but also

explained, and inserted in the historical, social and disciplinary context

of the time. Together with a rigorous historical framework, the book

offers also an educational discussion of the physical aspects presented.

Indeed, there are some specific sections and subsections with pedagogical

observations.

This book is intended for students pursuing STEM degrees, particularly

those seeking an understanding of the genesis and rationale behind quantum

mechanics. But it is surely also addressed to professional physicists who

are eager to reconsider the cultural foundations underlying the quantum

view of the world. We are thus thinking of inquiring minds, people who

teach quantum physics, and individuals involved in quantum technologies.
