Old Quantum Theory and Early Quantum Mechanics : A Historical Perspective Commented for the Inquiring Reader

This book provides a historical presentation of Old Quantum Theory andearly Quantum Mechanics integrated with comments and examples that helpcontextualize and understand the physics discussed. It consists in a detailed analysis of the usual topics that have mostcontributed to the birth and the development of Quantum Mechanics(black-body spectrum, atomic models, EPR paradox, etc.), but also dealingwith ideas, concepts and results that are not usually treated (vortexatoms, discussion on the meaning of the term “electron”, non-quantummodels of the Compton effect, etc.).

The time span taken intoconsideration goes mainly from the 1880s to the 1940s; but some briefnotes 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 alsoexplained, and inserted in the historical, social and disciplinary contextof the time.

Together with a rigorous historical framework, the bookoffers also an educational discussion of the physical aspects presented. Indeed, there are some specific sections and subsections with pedagogicalobservations. This book is intended for students pursuing STEM degrees, particularlythose seeking an understanding of the genesis and rationale behind quantummechanics.

But it is surely also addressed to professional physicists whoare eager to reconsider the cultural foundations underlying the quantumview of the world.

We are thus thinking of inquiring minds, people whoteach quantum physics, and individuals involved in quantum technologies.
