Engineering Methods for Analysing Strength and Rigidity – Glushkov

In this post, we will see the book Engineering Methods for Analysing Strength and Rigidity by G. Glushkov.


About the book

The book is a theoretical treatise on the subject of higher order moments. The theory of moments developed into a specific branch of mathematics which became a useful tool for solving com­plicated problems in structural mechanics. A number of Soviet scientists developed the so-called moment-operational method, which has proved to be extremely efficient for solving various pro­blems of modern engineering. These problems arise when non-linear elasticity must be taken into account, when precise designing of non-uniform structural elements is required, when the loading of a structure is essentially non-uniform, etc.

The moment-operational method has been widely employed for compiling manuals containing numerous tables and formulas for designing beams, arches and frames. A number of scientific research works and textbooks present the theory of moments of higher order methods examples of problems solved by the moment-operational method.

The knowledge of the theory of higher moments as well as of the moment-operational method will serve to extend the field of their application to new problems.

The book was translated from the Russian by N. Lebedinsky and was published by Mir in 1974.

Questions and Answers in School Physics – Tarasov and Tarasova (LaTeX version)

In this post, we will see the book Questions and Answers in School Physics by Lev Tarasov and Aldina Tarasova. This post is for the LaTeX version of the book, earlier scanned book can be found here.
Tarasov-Tarasova-Questions-And-Answers-In-School-Physics-MirTitles-2020 copy

This book holds a special place for me, as this book helped me understand many subtle points in physics. Also, this was the first book that I have ever scanned and had added to gigapedia when it was extant. Also, this was one of the first books that I took to typeset in LaTeX, almost a decade back, but gave up after many attempts and the project was untouched for several years. At end of 2019 I restarted the work and here we are.

One major challenge remains to convert the 130 odd diagrams to purely LaTeX using TikZ. I have done this for some figures (~6-7), but most of them are from the scans. I will do it as and when time allows. And of course you are free to contribute as well. Any help in this regard would be highly appreciated.

I have done a round of copy-editing, but still minor typos may exist here and there, (hopefully there are no major typos or screw-ups). So do report if you find any. Earlier scan had two pages which were missing (pages 36-37), they have been added in the current version, so this version is complete. We have also re-scanned the full page figures of section heads and coloured them. Many thanks to psmitak for the scans!

About the typesetting
The typesetting was fun, and I am pleased with the results. A lot of help was derived from questions on

The main font used isURW-Garamond with mathdesign, while the sans font is TeX Gyre Adventor. The template used for the typesetting is tufte-book and the paper size is b5. The colour scheme used is Maroon and SteelBlue from svgnames of xcolor package of LaTeX along with DarkGray. I have, at times, highlighted questions using Maroon and answers or pedagogically significant remarks using SteelBlue. This is mostly done, if not completely done. Hope that this typeset version is helpful!

Structural Design – Baikov, Strongin

In this post, we will see the book Structural Design by Baikov and Strongin.

Rydnik-ABCs-of-Quantum-Mechanics-Mir-2020 copy

About the book

The book presents a systematic and step-by-step approach to the physical and mechanical properties of concrete, reinforcing steel, reinforced concrete, masonry, and struc­tural steel.

The theoretical basis and design principles for reinforced concrete, masonry, and steel structures have been brought in line with new standards which were put in force in the Soviet Union since January, 1977. The material is presented with emphasis on Soviet, practice in highly industrialized precast reinforced concrete, type-design structural elements, and high-strength materials.

A good deal of attention is given to special engineering structures for water supply, sewage disposal, and heat supply systems, including tanks, settlers, aeration filters, aeration tanks, water lowers, buried conduits and headers, and heat-pipeline structures.

Carefully worked design examples are shown throughout the book, and an appendix gives a selection of design charts associated with the basic Soviet codes of practice.

Intended as textbook for students of building, civil, and structural engineering, the book will also be of interest to students in other departments and practising engineers.

The book was published by Mir in 1980 and was from the Russian by Alexander Kuznetsov.

Many thanks to Akbar Azimi for providing the original scans. We cleaned the 2-in-1 scan and created the pdf. There might be some warping in few of the pages, but overall it is very readable.

ABC’s of Quantum Mechanics – Rydnik (LaTeX version)

We have already seen this book earlier. But this post is to bring to your notice the electronic version of the book typeset using LuaLaTeX.

Rydnik-ABCs-of-Quantum-Mechanics-Mir-2020 copy

The book has come out nicely. Of course, it could have been better! I have typeset it in A5 paper, with 12 pt font with LuaLaTeX. The font used is EB Garamond. I have tried to maintain the typesetting of the original book with no chapter numbers or section numbers.

The table of elementary particles and their properties was one of the more challenging tasks in this otherwise simple book to typeset. It took me almost a day to just typeset this table. The rest was easy.

Screenshot 2020-04-04 at 18.40.17I have also created the front and back covers using TikZ, the first time I have tried this. Though they could have been done better.

The Internet Archive Link

The source files can be found at the gitlab project page:

Note: The original scan (by itanveer) which we had cleaned and posted had two pages (258-259) missing. I had already made a draft post asking for help for these two pages from people who might have the book, as I do not currently have the access to my physical collection. Except for these two pages, the rest of the book was processed and ready. Serendipitously, just a couple of days back Hemant Garach commented on the earlier post saying that he has this book! I requested him to scan these two missing pages and thanks to him we now have the complete book!

TODO: What remains to be done (in order of need):

  1. One more round of copy-editing. Though I tried my best, there will be many small typos here and there. I hope I have not screwed up in any major way. A thousand eyes are better than just two!
  2. Recreating figures (and front cover) using TikZ or other tools, so that it becomes completely electronic. For this release, I have used the scanned raster figures. Some actual photos of cloud chambers and particle tracks can be used instead of the current ones.
  3.  There has been much increase in our knowledge of particle physics (both empirical and theoretical) ever since the book was written in the 1960s. The book itself might be expanded as much of the information might seem dated to a particle physicist. Perhaps a new expanded edition of the book covering the era from the 1970s to present? Anyone interested?!

Collection of Problems on the Dynamics of a Point in a Central Force Field – Polyakhova

In this post, we will see the book by Ye. N. Polyakhova titled Collection of Problems on the Dynamics of a Point in a Central Force Field.

About the book

The collection is a detailed selection of problems on the dynamics of the motion of a material point acted on by a central gravitational force, in particular, the dynamics of space flight. As an exception, the book presents several problems on the motion of a point acted on central non-gravitational forces. The book is written mainly for correspondence students. Topics covered include Kepler’s laws, the integral of areas, Binet’s formulas for central forces, the energy balance and velocity along a space trajectory, time of motion along a space trajectory, conditions for the existence of elliptical trajectories, transfer from orbit to orbit, sphere of action, third escape velocity problems, two-body problem, and the generalized third law of Kepler, along with miscellaneous problems.

This collection is a textbook for the course of theoretical mechanics (“Point Dynamics” section). students in correspondence departments of Leningrad State University and other higher educational institutions used in part by students in the day and evening departments. Moreover, the problem book may prove useful for beginning instructors in providing practical exercises mechanics, particularly, when they prepare modifications of test problems.

Most of the collection is a detailed sampling of problems on the dynamics of a material point acted on by gravitational force, in particular, problems on the elementary dynamics of space flight. Several problems on the motion of a point acted on by central non-gravitational forces are presented. Altogether, the collection includes about 200 problems of varying degrees of difficulties, with solutions.

Translation of Sbornik zadach po dinamike tochki v pole tsentral’nykh sil, Leningrad, Leningrad University Press, 1974, pp. 1-145. The book was published by NASA in May 1975 under its technical translation programme (NASA TT F-16,263).

Linear Algebra And Multi Dimensional Geometry – Efimov, Rozendorn

In this post, we will see the book Linear Algebra And Multi Dimensional Geometry by
N. V. Efimov, E. R. Rozendorn

Efimov, Rozendorn - Linear Algebra and Multi-Dimensional Geometry - Mir fc

About the book

This book was conceived as a text combining the course of linear algebra and analytic geometry. It originated as a course of lectures delivered by N. V. Efimov at Moscow State University (mechanics and mathematics department) in 1964-1966. However, the material of these lectures has been completely reworked and substantially expanded. We have tried to bear in mind the requi­rements of other mathematical disciplines and also of mechanics and physics. We hope that all parts of the text will be useful. The only preparation required for this text can be given an a first- semester course of analytic geometry and algebra at the most ele­mentary level. All that is needed is a firm grasp of the elements of these subjects. For Chapter XII the student should be ac­quainted with projective transformations and the projective pro­perties of figures in the plane. Also, in Chapter X the reader may simplify his task by skipping Subsections 13 to 23 (Section 3) and Subsection 10 of Section 7. What is left of Chapter X can serve as a minimal algebraic basis for the theory of multidimensional in­tegration.
It may be noted in conclusion that the first five chapters already contain material with broad applications in mathematics, mecha­nics, and physics. These chapters, supplemented with some of the material of subsequent chapters, can be utilized in higher tech­nical schools with a more advanced mathematics curriculum.


The book was translated from the Russian by George Yankovsky and published by Mir in 1975.

Many thanks to shankar.leo for providing the scans and the pdf.

The Internet Archive Link

Note: I tried to optimise the file for size, but somehow the archive kept on rejecting for some error in the pdf. I could have tried a few more things, but didn’t get time for that, hence the delay in post. For now, hence this large file (~120M) was uploaded. This file is OCRed but without bookmarks and pagination.

I will try to update a smaller file in the future, or if someone can add a link to a smaller file,  it would be great.

About the book

At the Crossroads of Infinities is a story about the struggle of ideas out of which the modern physical picture of the world was born. Can anything move faster than light? Is the uni­verse finite or infinite? Is time revers­ible? What lies at the basis of the realities which we perceive as space, time or matter? These are the questions taken up in this book. And more, for it also tells of the roads of know­ledge, of the way man has probed the mysteries of the infinitely large and infinitely small, yet at root in­tegral world. (From the Front Jacket)

The book is a tour of the development of ideas of modern physics at the beginning of the 20th century. The book covers historical as well as philosophical issues which are at the core of modern physics. The struggle of ideas which the creators and developers of quantum mechanics and special relativity had to deal with is described very well.

The book was translated from the Russian by Vladimir Talmy and was published by Mir in 1971.

Origin and Chemical Evolution of the Earth (Science for Everyone) – Voitkevich

In this post, we will see the book Origin and Chemical Evolution of the Earth by G.V. Voitkevich.  Earlier, we had seen Origin and Development of Life on Earth by the same author, which can be seen as a companion volume to the one in this post.

This is a book in the Science for Everyone Series. With this post, we have almost completed this series. As of now, we have updated all the dead links with Internet Archive ones. Next, we will update the Little Mathematic Library.

Now only ONE book in this series remains (Earth, Sweet Earth by Ekaterina Radkevich (1990)). Many people contributed to this collection becoming almost complete, a big thanks to all those who have contributed to making this possible.


About the book

One of the most important problems in modern science is the origin of the Earth and formation of its shell. Modern views on the chemical composition of meteorites, planets and other bodies of the Solar System are pres­ented in this book. On the basis of recent achievements in cosmochemistry, the author, who is one of the leading scientists in the field of geochemistry, geophysics, describes the most probable processes that determined the chemical composition of the Earth in the remote past. Prof. George Voitkevich is also a winner of the Kar­pinsky Prize, which is given to a scientist for outstand­ing work in geology by the USSR Academy of Sciences. (From the back cover)

In this book the author attempts to describe in popular form some problems of the Earth’s origin and its chemical changes over its long geological history on the basis of cosmochem­ical, geochemical and geophysical data ob­tained in recent years. The chemical evolu­tion of the Earth is part of the chemical evolu­tion of Space. Modern cosmochemical and geo­chemical data reveal that the chemical history of the Earth as well as of other bodies of the Solar System is associated not only with pre­served stable and nonstable isotopes but also with extinct radioactive isotopes, including the isotopes of transuranium elements. (From the Introduction)

The book was translated from the Russian by V. F. Agranat and V. F. Pominov and was first published by Mir in 1988.

Puppets Without Strings (Science for Everyone) – Varshavsky, Pospelov

In this post, we will see the book Puppets Without Strings: Reflections on the Evolution
and Control of Some Man-Made Systems by V. I. Varshavsky, D. A. Pospelov. This is another book in the Science For Everyone series.


About the book

Paradoxes in the evolution of technological systems. Who designed the global telephone and communication network? The whole is the sum of the parts plus their interactions. Is a simple data register really simple? Automata exploring unknown worlds. Optimum or expediency? Random interactions and information exchange. Daydreaming and cynical automata.

“I thought he thought I thought he. .. .” Heterogeneity in a group of automata is a key to success. Are we haunted by the ghost of Erehwon City? Puppets without strings: who is the puppeteer? Boundaries of centralization. How do systems evolve?
A fresh look at design. Evolution goes on. (from the Back Cover)

We seek to present a popular account of the control problems that arise in complex systems which are more generally called large-scale systems in control theory. In systems of this kind, centralized control often gives way to decentralized control, the transition being a penalty for the system’s complexity. This is because the system’s complexity makes centralized con­trol either inefficient or impracticable. How do large-scale systems arise, and is it possible that the category of large-scale system is merely a far-fetched nothing? We have tried to show in this book that large-scale man-made systems which sur­round us are steadily becoming more nu­merous and still more complex. The evolu­tion of man-made systems out of the already existing ones goes on in much the same way as living organisms evolve. Decen­tralized control is but a natural product of this evolution. We hope to convince our readers that it is just so. (from Instead of a Preface)

The book was translated from the Russian by A. Kandaurov and was first published by Mir in 1988.
