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.

i-v-savelyev-fundametals-of-theoretical-physics-vol-1_0000 i-v-savelyev-fundametals-of-theoretical-physics-vol-2_0000

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.

Physics A General Course – Savelyev

In this post we will see the three volume Physics – A General Course by I. V. Savelyev.

I have done everything in my power to acquaint students with the basic ideas and methods of physics and to teach them how to think physically. This is why the book is not encyclopedic in its nature. It is mainly devoted to explaining the meaning of physical laws and showing how to apply them consciously. What I have tried to achieve is a deep knowledge of the fundamental principles of physics rather than a shallower acquaintance with a wide range of questions.

While using the book, try not to memorize the material formalistically and mechanically, but logically, i.e. memorize the material by thoroughly understanding it. I have tried to present physics not as a science for “cramming”, not as a certain volume of information to be memorized, but as a clever, logical, and attractive science.

Notwithstanding my desire to reduce the size, I considered it essential to include a number of mathematical sections in the course: on vectors, linear differential equations, the basic concepts of the theory of probability, etc. This was done to impart a “physical” tinge to the relevant concepts and relations. In addition, the mathematical “inclusions” make it possible to go on with the physics even if, as is often the case, the relevant material has not yet been covered in a mathematics course.
The present course is intended above all for higher technical schools with an extended syllabus in physics. The material has been arranged, however, so that the book can be used as a teaching aid for higher technical schools with an ordinary syllabus simply by omitting some section

Fundamentals of Physics – Yavorksy and Pinsky

In this post we will see the long awaited two volume Fundamentals of Physics by B. M. Yavorsky and A. A. Pinsky.

 

This textbook explains the con­cepts and most important advances of modern physics without resort to higher mathematics. Avoids the traditional division between clas­sical and modern physics and en­deavours to present all material so as to develop quantum mechanical concepts.

The textbook is intended for secon­dary schools and as a teaching aid for physics teachers in general and technical secondary schools. Will be found useful by correspondence students studying ‘A ’ level and first year physics.

Contents.

Vol. I. Motion and Forces, Conservation Laws, Molecular Kinetic Theory of Gases, Molecular Forces and states of aggregation of matter, Electrodynamics

Vol. II . Vibrations and Waves. Quantum Physics of Atoms, Molecules and Solids. Physics of the Nucleus and Elementary Par­ticles.

A Course of Differential Geometry and Topology – Mishchenko, Fomenko

In this post we will see A Course of Differential Geometry and Topology – A. Mishchenko and A. Fomenko. Earlier we had seen the Problem Book on Differential Geometry and Topology by these two authors which is the associated problem book for this course.

mishchenko-fomenko-a-course-in-differential-geometry-and-topology

About the book

The present course deals with the fundamentals of differential geometry and topology whose present state is the culmination of contributions of generations of mathematicians.

The English edition has been thoroughly revised in line with comments and suggestions, made by our readers, the mistakes and misprints that were detected have been corrected. This is essentially a textbook for modern course on differential geometry and topology, which is much wider than the traditional courses on classical differential geometry, and it covers many branches of mathematics a knowledge of which has become essential for a modern mathematical education. We hope that a reader who has mastered this material will be able to do independent research both in geometry and related fields. To gain a deeper understanding of the material of this book, we recommend the reader should solve the questions in A. S. Mishchenko, Yu. P. Solovyev and A. T. Fomenko Problems in Differential Geometry and Topology which was specially compiled to accompany this course.

 

The book was translated from the Russian by Anatoly Talshev and was first published by Mir in 1988.
