## Fundamentals of Theoretical Physics – Savelyev

In this post we will see the two volume set titled Fundamentals of Theoretical Physics by I. V. Savelyev. Previously we have seen Physics A General Course by the same author.

The book being offered to the reader is a logical continuation of the author’s three-volume general course of physics. Everything possible has been done to avoid repenting what has been set out in the three-volume course. Particularly. the experiments underlying the advancing of physical ideas are not treated, and some of the results obtained are not discussed.

The book has been conceived as a training aid for students of non- theoretical specialities of higher educational institutions. I had in mind readers who would like to grasp the main ideas and methods of theoretical physics without delving into the details that are of interest only for a specialist. This book will be helpful for physics instructors at higher schools, and also for everyone interested in the subject but having no time to become acquainted with it (or re- store it in his memory) according to fundamental manuals.

The books were translated from the Russian by G. Leib and was first published in 1982.

We have added new covers to existing pdfs. All other credits to original uploaders. Thanks to commentators for points the libgen links.

You can check old book shops if you are in India. Otherwise there are still some sites which sell them though at a much higher price

Can you please make “Physics a refresher course – Yavorksy” and “Algebra and analysis of elementary functions – Popatov” priority posts? I can’t find the former anywhere and the latter is overpriced.

Hey guys!
Thank you so much for all your effort and great job.
About “Fundamentals of Theoretical Physics – Savelyev”, I would just like to let you know that pages 176 and 177 of volume 2 are missing. Please add them!
Thanks again.
