इस पुस्तक के बारें में

इस पुस्तक में लेखक ने सरस ढंग से नन्हें-मुन्नो का भौतिकी की मुख्य परिघटनाओ व नियमों से परिचय कराया है। स्कूल में पढ़ाई शुरू करने से पूर्व भौतिकी की विभिन्न धारणाओं को अच्छी तरह समझने के लिए ये पुस्तक बच्चों को केवल पढ़कर सुनना ही पर्याप्त नहीं है।इसके लिए इसमें वर्णित परिघटनाओं का बड़ों के साथ बैठकर प्रयोग तथा प्रेक्शन करना सर्वाधिक महत्वपूर्ण है। आशा है की रंगबिरंगी तस्वीरें पुस्तक को भली-भाँति समझने में काफ़ी सहायक सिद्ध होगी।

पुस्तक बच्चों और माता-पिता के एक साथ बैठकर पड़ने के उद्देश्य से लिखी गयी है।

About the book:

In this book author has introduced main phenomenon and laws of physics to children in a simple way. Before starting the learning at school it is not sufficient to just read out this book to children for understanding various concepts in physics. For this, it is important the phenomena described in this book should be experimented and observed. We hope that the colourful pictures in the book will help in the understanding of the book.

This book has been written with the purpose of parents and children reading it together.

The sections cover major concepts in physics like sound, light, heat, speed, time, electricity and magnetism. The book is profusely illustrated with photographs of actual physical setups using dolls and other play materials.

The book was translated to Hindi from Russian by *Ramindra Pal Singh *and was published by Mir in 1987.

About the books:

The purpose of the present book is to offer the reader an attempt at a systematic exposition of rules for rational designing.

With all the diversity of the modern, machine-building the tasks facing the designer are similar in many respects. It is the reduction of the weight and specific metalwork weight of the machine, the improved suitability for industrial production, greater durability and reliability that are of importance for the design of any machine, the difference lying only in the relative significance of these factors. All this enables one to formulate the principles of rational designing as a code of general rules for machine building.

The prime intention of the book is to make the designer learn to work creatively. To design imaginatively means: to abstain from blindly copying the existing prototypes and to design meaningfully, selecting from the entire store of the design solutions offered by the present-day mechanical engineering the ones that are most suitable under given conditions; to be able to combine various solutions and find new, better ones, i. e., display initiative and put vim in the work; to continually improve the machines’ characteristics and to contribute to the progress in the given branch of mechanical engineering; to follow the dynamic development of the industry and devise versatile machines of long life, amenable to further modernization and capable of meeting the ever-growing demands of the national economy without running the risks of obsolescence for a long time to come.

Particular attention in the book is attached to the problems of durability and reliability. The author endeavoured to strongly emphasis the leading role of the designer in tackling these problems. In presenting the material the author followed the principle “qui vidit—bis legit” (the one who sees reads twice). Most of the designers are individuals of visual thinking and visual memory. For them a drawing or even a simple sketch means much more than many pages of explanatory notes. For this reason, each point in the text is accompanied by design examples.

To better the understanding most of the illustrations are arranged in such a way as to enable it to compare wrong and correct, inexpedient and expedient design versions.

The solutions given as correct are not the only possible ones. They should be regarded not as precepts, suitable for use in all cases, but rather as examples. In particular conditions other versions may prove more advisable.

]]>…This book is devoted to one, but sufficiently general operational method, which absorbs many operational methods known to date and allows for the uniform solution of both classical problems, involving differential equations with partial derivatives, and the absolutely new problems of mathematical physics, including those connected with non-linear equations in partial derivatives.

…This book on operational methods should be accessible to senior course students of mathematics and physics faculties at universities and departments of applied mathematics. This means that only a knowledge of classical analysis is required of the reader. The book provides explanations in sufficient volume of such concepts as the theory of Banach algebras of distributions (Chapter I), the theory of linear differential and difference equations (Sees. 1, 2, and 3 of Introduction), the theory of non-linear equations of the first order with partial derivatives (Chapter IV). This material may be also of use to the reader who is already familiar with these questions, because rather often it is not presented in traditional style, and adapted for further reference. The reader who studies the book thoroughly will be equipped to carry on independent research in the modern theory of linear, non-linear differential and differential-difference equations with partial derivatives.

…This book has been written in such a way as to serve the widest possible circle of readers. It is suitable for two methods of study. The reader, who seeks to avoid fine assessments and passing to the limit and only wishes to master the practical techniques for obtaining asymptotic solutions, may omit that part of the book which is devoted to functional analysis.

…The most effective way of mastering the subject, however, consists rather in first reading Introduction and then reading all the book in succession. The reader should nevertheless be warned that all these methods are not at all easy, because the book provides a new operational calculus-the calculus of ordered operators.

The book was translated from the Russian by V. Golo, N. Kulman and G. Voropaeva and was published by Mir in 1976.

About the book:

The new edition of Strength of Materials by N. M. Belyaev has been published after 11 years. In 33 years that lapsed between the publication by N. M. Belyaev of the first edition in 1932 and the last fourteenth edition in 1965 a total of 675 000 copies of the book were sold, testifying to its wide popularity. During this period the book was periodically enlarged and revised by N. M. Belyaev and, after his death in 1944, by a group of four of his co-workers. This group, which prepared from the fifth to the fourteenth editions for publication, did not consider it proper to make substantial changes in the original work of N. M. Belyaev. Additions were done at one time or another only when they became absolutely necessary due to changes in standards and technical specifications and in the light of recent research.

In the present edition, prepared by the same group, a number of topics have been dropped either owing to their irrelevance to strength of materials or because they are rarely taught in the main course.

Considering the availability of a large number of problem books (see, for instance, Problems on Strength of Materials edited by V. K. Kachurin) on the market, most of the examples have been dropped from the present edition. Only examples that are essential for the explanation of theoretical part have been retained. For greater compactness the problem of design for safe loads has now been included in Chapter 26 For the first time the chapter includes the principles of design for limiting states, which though beyond the limits of the basic course of strength of materials are important enough to require an exposition of the basic concepts even at this stage of teaching.

The problems of strength, which in the previous editions occupied two chapters, have been grouped into one. The part dealing with actual stresses has been transferred to Chapter 2, where it has been presented in a sufficiently detailed manner. The tables containing data on materials have been dropped from the appendices. A part of the data on materials has been transferred to 8 Preface to the Fifteenth Russian Edition corresponding sections. The obsolete steel proliles grading has been replaced by new ones.

As in the previous editions it was our endeavour to preserve Belyaev’s style and method of presentation of material. Therefore the author’s text has in general been preserved. If Nikolai Mikhailovich Belyaev were alive today he would possibly write many things in a different way. However, since the book won wide popularity as written by N. M. Belyaev, we tried to preserve the original text as far as possible.

(perhaps someone with an engineering background can post a much better review)

The book was translated from the Russian by N. K. Mehta and was published by Mir in 1979. This is the fifteenth edition of the book.

About the books (From the preface of the first volume):

One of the problems facing the modern theory of mechanisms is the study and systematization of the huge inheritance accumulated in mechanical engineering practice and consisting of numerous mechanisms applied in various machines, instruments and devices.

An analysis of this data and its classification into the various kinds of mechanisms have shown that their systematization should be broken down into two stages. The first is the compilation of collections of mechanisms employed in all branches of the engineering industries. The next stage consists of collections compiled for different branches, such as mechanisms for precision instruments, mechanisms of machine tools, mechanisms of aircraft engines.

The need of such systematically compiled data is evidently very great because information on the various kinds of mechanisms that have been devised is scattered, for the most part, among diverse reference sources: textbooks, monographs, journals, patent applications, etc. This data is difficult to use because some of the editions may be more or less unique, and because the data does not, as a rule, contain the necessary descriptions, classification and system that would enable a mechanism to be quickly selected for some definite purpose specified by a designer.

It is of equal importance, in the author’s opinion, to meet the needs of inventors. A vast number of inventions are being made in “the USSR and’abroad, and their quantity is increasing year by year. Inventors require convenient handbooks where they can readily find elementary schemes of mechanisms’ that can accomplish the forms of motion needed for the designs they propose.

To meet this demand, in 1947-52 the author compiled a four-

volume work called Mechanisms which was published (in Russian) by the USSR Academy of Sciences. This work contains drawings and descriptions of 4000 mechanisms and includes those made up of hydraulic, pneumatic and electrical devices, as well as purely mechanical systems. This four-volume work has long been out of print and, judging from letters received by the author from a great many engineers, designers, technicians and inventors, a new edition is more than timely. To meet this demand the author has prepared the present completely revised and considerably supplemented edition. This

work is to comprise five volumes. The first two volumes contain drawings and descriptions of lever mechanisms, i.e. mechanisms based on kinematic chains made up of lower pairs. The third volume is devoted to gear mechanisms. The fourth volume contains cam, friction and flexible-link mechanisms. The final volume is to deal with hydraulic, pneumatic and electrical mechanisms.The author’s aim was to produce a handbook for engineers and technicians of all ranks, as well as inventors, and not only for experts in the field of mechanisms theory. Hence, he has conscientiously avoided special terminology and notation intelligible only to experts in this line. The author has tried to use the simplest possible drawings furnished with the simplest possible descriptions that should be understandable even to persons without any special engineering training.

The books were translated from the Russian by Nicholas Weinstein and were first published by Mir in 1976 and reprinted in 1979.

About the book:

How can events 150 million kilometres away affect us here on earth? But if you have ever complained of poor radio reception, if the compass needle has ever gone wrong, if you have ever wondered what has happened to the weather, the trouble most likely has to be sought at this great distance. Blame it all on the sun. This book is an account of that great world-wide undertaking— the International Quiet Sun Year— in which scientists of over 60 countries participated. Following the International Geophysical Year, it disclosed many secrets about our luminary. Everyone who wants to learn more about our sun and how it affects the planet we live on should read this book.

The book was translated from the Russian by George Yankovsky and was published by Mir in 1968.

About the book (from the back cover):

This book is about our planet, the Earth we know so well. But is it then a planet of riddles? Read this book, and you will see that it is.

Whence the strange names of the sections: “Embracing the Boundless”, “Seeing the Invisible”? Has the author forgotten Kozma Prutkov’s aphorism: “You can’t embrace the boundless”? Not at all! But he does not agree.

The book gives a brief history of the study of our planet. But history contains the roots of scientific novelty, of wonderful discoveries. Kozma Prutkov also said, and not without reason: “Heed the roots!”

The book explores a variety of topics related to the Earth. It forays into areas of astronomy, geology, physics to ask questions and explain the physical origin of the objects and events we see on the Earth. For example, it also explains how the mud is formed. Peppered with historical anecdotes and updated with the latest scientific research (until the date of publication) this is an amazing read.

The book was translated from the Russian by *David Sobolev, *and was first published by Mir in 1972, with a reprint in 1974.

About the book:

This study aid is intended for students of physical and mathematical faculties of pedagogical institutes.

The book contains about 2000 examples, problems, and exercises of which 1700 problems are for solving independently. Along with rather simple problems, there are also problems whose solution requires serious and sometimes inventive work. In the course of preparing the manuscript for print we tried to distribute the space among the basic types of “school” problems in algebra and trigonometry. Solving these problems will help the student to acquire professional skill necessary for a teacher who must know how to solve mathematical problems of the high-school level.

This book is not only a collection of problems, it is rather a study aid for practical work, as can be seen in the structure of the text book. Each section contains necessary theoretical material and an ample number of worked examples (the total number of which amounts to about 300), which are very useful for the student pri marily from the methodological point of view.

The book was translated from the Russian by Leonid Levant and was first published by Mir in 1987.

]]>About the book (from the front jacket)

Have you ever stopped to think how many colours there are in a rainbow? Seven or, perhaps, nine as the title of the book suggests? It appears, there are many more and still the title is correct. Why so?The book will tell you what is visible and invisible light, how it helps man to acquaint himself with his environment, investigate it, penetrate into the mysteries of matter and space. You will also find out how man learned to see in the dark, transmit images over long distances and record processes occurring within millionth fractions of a second. The book contains a wealth of other information on the latest achievements in science and technology.The author, Alexander Steinhaus, is a Soviet specialist in electronics and TV. Many years of industrial experience served as a fertile ground for his literary career on which he embarked with ardour. He has written many sci-fic articles, some stories and a few books, among which are “The Nine Colours of the Rainbow”, “A Factory Without Men”, and others. At present A. Steinhaus is working at a large sci-fic book on television.

The book was translated from the Russian by David Sobolfy and was published by Mir in 1966.
