Algebra Distractivă by I. I. Perelman (Romanian)

Posted on May 30, 2024 by The Mitr

In this post, we will see the book Algebra Distractivă by I. I. Perelman (Algebra for Entertainment in Romanian).


About the book

Prima ediție a  Algebra Distractivă a apărut în anii nouăzeci și a fost destinată un viitor minunat de a aduce sute de mii de tineri în pliul matematicii și minunile sale. Este scris sub formă de schițe pline de viață care discută despre multifarious (și interesant!) aplicații ale algebrei în lumea despre noi. Aici întâlnim ecuații, logaritmi, rădăcini, progresii, analiza diofantină antică și faimoasă și multe altele. Exemplele sunt picturale, vii, adesea pline de spirit și scot în evidență esența problemei la îndemână. Există numeroase excursii în istorie și istoria algebrei. Destul de natural, o serie de lucruri sună puțin demodate-vremurile s—au schimbat!- dar eforturile câștigătorului premiului Lenin, V. G. Boltyansky, care a editat cea mai recentă ediție și a adăugat o mulțime de materiale proaspete din lumea computerelor, au dat o lustruire suplimentară acestei bijuterii a divertismentului. Nimeni care a citit această carte nu va mai privi vreodată matematica într-o lumină plictisitoare. Recenzionarii o consideră unul dintre cele mai bune exemple de scriere științifică populară.The book was translated from Russian and was illustrated by . The book was published in by Publishers.

Geometry for Entertainment – Yakov Perelman

Posted on May 30, 2024 by The Mitr

In this post, we will see the book Geometry for Entertainment by Yakov Perelman. This is a new English translation of the book from the original Russian published in 1950.

About the book

Geometry for Entertainment is written both for friends of mathematics and for those readers from whom many attractive aspects of mathematics have somehow been hidden.

More importantly, this book is intended for those readers who studied (or are currently studying) geometry only at the blackboard and therefore are not used to noticing familiar geometric relationships in the world of things and phenomena around us, have not learnt to use the acquired geometric knowledge in practise, in difficult cases of life, on a hike, in a bivouac or front-line situation.

To arouse the reader’s interest in geometry or, in the words of the author, “to inspire a desire and cultivate a taste for its study is the objective of this book.”

Release Notes

Yakov Perelman’s books always have had a special place in my heart. Several of his classic works are translated, though this one was not. This was a rather ambitious first project of translating an entire book, I was not sure if I could complete it in a reasonable time frame. To my own surprise the project got completed in little over a month: first commit on 25 April and last on 30 May 2024. I took help from several online translators for the translations. I did learn to read a bit of Russian in the process. 🙂

Hopefully there are no major blunders in the translation. Please do let me know if you find any errors either in the translation or the mathematics.

Though I have credited the link on the Internet Archive (IA user Philipp Zanko aka Russian Lutheran), I must thank the original scanner who made this file available (if it was not Russian Lutheran). The processing of these scans was done with GIMP (for selection and editing) and Inkscape (for vector pdf conversion). The final file size is slightly larger (~ 55 M) primarily due to the heavy illustrations. They were converted to vector pdf for the book from the original scans.

I have use LuaLaTeX engine for compilation and Linux Libertine font for the book. The typesetting in LaTeX also provided several challenges which were sorted through expert help at tex.stackexchange. I have used a square profile for the book with wide margin which allows for a nicer reading.

The book is released with an open but a restrictive license, CC By NC SA. We might go for a print version of the book (though others are still pending ikik), this step is towards that goal.

Overall, I am very satisfied with the outcome, and it gives me great pleasure to share it with you. I hope you enjoy reading it too. I am optimistic that this is first of many translations of to come. Do wish me luck!

Damitr Mazanav – “The Mitr”

PS: An electronic version of Astronomy for Entertainment updated with all the recent discoveries in astronomy is in the pipeline, hopefully we should see its release in next couple of months. Also, Irodov’s Fundamental Laws of Mechanics and Basic Laws of Electromagnetism are about ready (figures remain to be redrawn).

Update/Edit: 01 June 2024

Apparently the book has been taken down from Internet Archive with allegations that I have “copied” verbatim from another English translation of the book. Frankly, I was not even aware of the “other ” translation. One of the allegations is that since I don’t know how to read Russian hence I cannot translate. But this is exactly where online translators come in. Without them I wouldn’t have dared to touch this project.

Anyway here are the screenshots of how the book was translated from scratch page-by-page, para-by-para.  I have a complete logs from page one to last page. Not sure what else can I do to convince someone that this translation was done my me and not “copied” from somewhere else.

Also attaching the Russian alphabet chart I created to “read” Russian.

 

And you can always check the git repo for how the typesetting of the book was done. But it seems some nefarious intent is there to stop the release of the book to the public.

We have challenged the removal with these proofs Lets see how it goes!

Tables Of Spectral Lines Of Neutral And Ionized Atoms by A. R. Striganov; N. S. Sventitskii

Posted on May 29, 2024 by The Mitr

In this post, we will see the book Tables Of Spectral Lines Of Neutral And Ionized Atoms by A. R. Striganov; N. S. Sventitskii.

About the book

Born in the Kalinin region in 1907 and a graduate of Moscow State University, Prof. Striganov currently heads the Atomic Spectroscopy Laboratory at the I. V. Kurchatov Institute of Atomic Energy and is a member of the Committee on Spectroscopy of the Academy of Sciences of the USSR. His research focuses on methods of atomic emission spectrum analysis, optical spectra studies, hyperfine structure of heavy element spectra, and spectroscopic diagnosis of plasmas.

The original Russian text was published by Atomizdat in Moscow in 1966 and has been updated by the authors for this edition. Last-minute additions and corrections have been incorporated into the tables for convenience, prioritizing content over typographic aesthetics. The tables of Spectral Lines of Neutral and Ionized Atoms were first published in Moscow in 1966, and for this Plenum Press edition, corrections have been made, and additions based on journal articles have been included. Notably, additions have been made for spectra such as Li, C I, NI, N IV, and N V.

Previously neglected spectra, like those of N IV, N V, 0 IV, 0 V, and 0 VI, have now been studied more extensively in the laboratory. The American edition of the book incorporates precise values for these spectra, drawing from recent comprehensive papers refining the system of energy levels and expanding the classified lines in various regions of the spectrum. While retaining certain lines from earlier sources, the authors calculated wavelengths based on the refined energy levels. The book aims to provide useful data on the spectra of 22 elements for physicists and engineers.

About the book

ముందుమాట

నేను చిన్న పిల్లాడిగా వున్నప్పుడు – యెప్పుడో, చాలా చాలా కాలంకితం – నా దగ్గర పినోచ్చియో లేదా చిన్న కొయ్య బొమ్మ” అనే పుస్తకం వుండేది. (ఇటాలియన్ భాషలో కొయ్య బొమ్మకి బురతీనొ అంటారు.)

బురతీనా సాహస కృత్యాల గురించి నేను నా స్నేహితులకి, మగపిల్లలకీ ఆడపిల్లలకీ, చెబుతూ వుండేవాణ్ణి. కాని ఆ పుస్తకం పోయింది. అంచేత ఆ పుస్తకంలో లేని రకరకాల సాహస కృత్యాలు చేర్చి కథని మార్చిమార్చి చెప్పేవాణ్ణి.

బాలలూ, యిప్పుడు యెన్నో యేళ్లు గడిచేయి. నా జ్ఞాపకాలు బురతీనా మీదకి మళ్లుతున్నాయి. అంచేత ఆ చిన్న కొయ్య బొమ్మ అతి సాహస కృత్యాల గురించి మీకు చెప్పాలని తీర్మానించుకున్నాను.

Foundations Of The Theory Of Plasticity by L. M. Kachanov

Posted on May 25, 2024 by The Mitr

In this post, we will see the book Foundations Of The Theory Of Plasticity by L. M. Kachanov.


About the book

This book is based on lectures on the theory of plasticity delivered by the author at the Mechanics-Mathematics Faculty of the University of Leningrad. The author has not attempted to provide an exhaustive treatment of the entire theory of plasticity. The book primarily focuses on the plastic deformation of metals at normal temperatures, particularly in relation to questions of the strength of machines and structures. Its main objective is to offer a straightforward explanation of the fundamental equations of plasticity theory and the most well-developed methods for solving them, as well as to discuss issues characterizing the special nature of the plastic state and the variety of mechanical problems involved.

The second edition has undergone significant revisions to reflect important developments in the theory in recent years. More emphasis has been placed on yield surfaces and the associated yield law, and the chapters on plane stress and the axisymmetric problem have been expanded. The section on extremum principles and energetic methods of solution has been extensively rewritten. Additionally, a new chapter on the theory of shakedown, which is significant in understanding the role of varying loads in the onset of rupture, has been included. Progress in the model of a rigid-plastic body in dynamic problems over the last decade has led to some additions in Chapter XI.

To prevent the course from being overloaded with unnecessary details, some of the more difficult problems have been omitted from the second edition, and the chapters on the stability of equilibrium and composite plastic media have been abbreviated.

It is assumed that the reader is acquainted with the basic concepts of strength of materials and the theory of elasticity. To facilitate study, passages that may be omitted on first reading have been indicated in small type or marked with asterisks.

The list of references is not exhaustive. Special lists are provided to assist in navigating the extensive literature on the theory of plasticity, which includes books and review articles containing supplementary references.

The author acknowledges readers who pointed out defects in the first edition and expresses gratitude to A.A. Vakulenko, A.I. Kuznetsov, V.I. Rozenblyum, and G.S. Shapiro for their valuable comments on the manuscript. A.I. Kuznetsov also reviewed the proofs, and the author extends sincere thanks to him for a number of important corrections.

Translation from the second revised edition into English was provided by Multilingua Scientific Translations.

Brazing And Soldering Of Metals by N. F. Lashko; S. V. Lashko-Avakyan

Posted on May 24, 2024 by The Mitr

In this post, we will see the book Brazing And Soldering Of Metals by N. F. Lashko; S. V. Lashko-Avakyan.

About the book

Soldering of metals and alloys, together with furnace welding, represents one of the oldest methods of securing a permanent joint between different parts. In order to distinguish fusion welding from other welding methods devised at the end of the last century, this method has been termed “soldering” by N.N. Benardos. Some basic principles of soldering laid down in ancient times and still applied today have proved to be insufficient for securing many kinds of permanent joints required for modern machinery building.

The intention of the authors of the present study has been to present known data on soldering processes in the light of their own experience as well as in the light of the general knowledge of the physical and chemical processes of soldering. The authors do not pretend to have given an exhaustive treatment of all the problems involved and admit that many of them still remain questionable.

The first section of the book deals with the distinguishing features of the design of soldered joints. Some problems concerning the interaction of liquid solders with the parts to be soldered, their crystallization, and internal structure of the soldered seam and its influence on the quality of the resulting connections are treated in the second section. Characteristic features of crystallization occurring in the soldered seam, as well as of the internal structure of the latter, have been published earlier in the authors’ study, “Physical Metallurgy of Welding”. In the third section, problems are examined connected with the selection of solders and fluxes required.

The fourth section deals with the basic methods of soldering, which are determined by the methods of heating the parts to be soldered and of removal of scale and oxide films, as well as by the methods of preparing solders. In the fifth and last section, essential features of soldering various alloys to different kinds of base metal are described.

Equazioni Della Fisica Matematica by A. N. Tichonov; A. A. Samarskij

Posted on May 23, 2024 by The Mitr

In questo post vedremo il libro .


A proposito del libro

Le questioni della fisica matematica sono strettamente legate allo studio dei processi fisici più disparati nel cui novero rientrano fenomeni studiati in idrodinamica, teoria della elasticità, elettrodinamica ecc. I problemi matematici che sorgono in questo caso contengono numerosi elementi comuni e costituiscono l’oggetto della fisica matematica. Il metodo di indagine, che caratterizza questa branca scientifica, è sostanzialmente matematico. Tuttavia l’impostazione dei problemi della fisica matematica, strettamente connessa allo studio di problemi fisici, ha dei tratti specifici.

La cerchia di questioni inerenti alla fisica matematica è estremamente ampia. Nel presente volume sono trattati problemi di fisica matematica che conducono ad equazioni alle derivate parziali. Abbiamo cercato di subordinare la scelta e l’esposizione del materiale alle proprietà caratteristiche dei processi fisici tipici, per cui la disposizione del materiale corrisponde ai tipi fondamentali di equazioni.

Lo studio di ciascun tipo di equazioni inizia dai problemi fisici elementari che conducono alle equazioni del tipo considerato. Un’attenzione particolare viene prestata all’impostazione matematica dei problemi, all’esposizione rigorosa dei metodi di soluzione dei problemi elementari e all’interpretazione fisica dei risultati ottenuti. Ogni capitolo contiene problemi il cui scopo principale è quello di acquisire esperienza pratica. Alcuni problemi presentano di per sé interesse fisico rilevante. Alla fine di ciascun capitolo sono date appendici contenenti applicazioni dei metodi descritti nel testo alla soluzione dei problemi più disparati della fisica e della tecnica e una serie di esempi che escono dai limiti dei problemi trattati nel testo. La scelta di questi esempi potrebbe, ovviamente, essere diversa.

Il libro contiene soltanto parte del materiale trattato nel corso di metodi della fisica matematica, senza considerare la teoria delle equazioni integrali e i metodi variazionali. I metodi approssimati sono esposti in modo non sufficientemente completo. Il libro è basato su lezioni tenute per un decennio da A. N. Tichonov alla facoltà di fisica dell’Università di Mosca.
