In this post, we will see the LaTeX version of the book *Basic Concepts of Quantum Mechanics* by Lev Tarasov. We had earlier seen a scanned version of the book.

# About the book

This book gives a detailed and systematic exposition of the fundamentals of non-relativistic quantum mechanics for those who are not acquainted with the subject. The character of the physics of microparticles and the problems of the physics of microphenomena (interference of amplitudes, the principle of superposition, the specific nature of measuring processes, causality in quantum mechanics) are considered on the basis of concepts about probability amplitudes. Besides, the quantum-mechanical systems – microparticles – with two basic states are analyzed in detail. The apparatus of quantum mechanics is considered as a synthesis of concepts about physics and the theory of linear operators. A number of specially worked out problems and examples have been included in order to demonstrate the working of the apparatus.

This book is meant for use by students of engineering and teachers-training institutes. It may also be used by engineers of different profiles.

The book was translated from Russian by Ram Wadhwa and was originally published in 1980.

It took some time to complete this project (~4 years, on and off working on it), but I feel it was worth it. I have used the tufte-book class for the typesetting. The fonts used are Linux Libertine for serif and sans from the same family Linux Biolinum, the typewriter font is from Computer Modern family. The results are very satisfying and aesthetically pleasing. They are close to the original formatting in many ways, though not the same. I have tried my best to avoid any typos, though there might be still some remaining. If you find any typos or mistakes please do leave a comment. There is still a lot of scope fine tuning the document, adjusting spaces, placements etc., covers being made natively with TikZ , but that can wait for another release. Next in Tarasov’s books we will see *The World is Built on Probability* in the electronic format.

Table of contents

Subject index (this took too long to make that I had anticipated)

Placing figures in the margins makes it easier.

Interludes have the take home points, and also present us with different worldviews while leading the discussions to next sections.

There are two typos in the cover alone (“micropehnomena” and “the he laws…”). 😦

Thanks, but it still says “ micropehnomena”.

Nicely done. I wonder it is possible to translate it to other languages. Do we need to pay for the copyright to Mir?
