Alexander Kitaigorodsky, D. Sc. (Phys. and Math.), graduated from the Lomonosov State University in Moscow. He is the author of numerous scientific works, textbooks and books on science for the layman. They include: The Structure of Matter, The Atomic Nucleus, Physics for Everyone (with Lev Landau as co-author), I am a Physicist, Renyxa, The Improbable Is No Fact, etc. His articles on the creation of new substances and materials of the future were published in the collection Things to Come. The present book deals with the solid, liquid and gaseous states of matter. One of its winning features, however, is that problems of structure are considered from a definite point of view, as a manifestation of the peculiar struggle between Order and Disorder in the atomic world. In his forces, the author was able to discuss, in addition to the fundamentals of the atomic structure of matter, a multitude of technological processes,.highly significant in our day, such as the conversions that occur in plastics and rubbers, or the annealing and plastic working of metals.
Neither did Professor Kitaigorodsky ignore problems concerning living tissues. Here again he finds that this unique mixture of order and disorder in the arrangement of biological molecules is of primary importance in understanding the laws of molecular biology.
The new, fifth, Russian edition, from which this translation has been made, was revised and supplemented with much important up-to-date material. Owing to its simple language and exposition, this book will be of interest to readers acquainted with only the fundamentals of physics.
Translated from the Russian by Nicholas Weinstein

It must be emphasized that this book is not an ordinary textbook
but one in which certain carefully selected topics of theory and an
abundant amount of problem solving will enable the student to expand
and deepen his knowledge of the school course of elementary mathematics
and enable him better to begin the study of higher mathematics
in higher educational institutions. The topics chosen here for detailed
discussion are those that usually cause the most trouble or do not,
fora variety of reasons, receive the attention they deserve. The most complicated
and important parts of elementary mathematics are analyzed
and illustrated in detailed problem solving and subsequent discussion.
Particular attention is paid to analyzing typical mistakes of the student.
Another point to bear in mind is that the authors consider only the
more traditional topics of elementary mathematics. They do not use
methods of analytic geometry or differential and integral calculus; in
geometry, axiomatics is not dwelt on, nor is the terminology of set
theory made much use of.
This textbook is supplied with a large number of problems in the
form of exercises appended to each section. The answers are given at
the end of the book.
This book is aimed at a broad range of readers, from students of
secondary school to students of teachers’ colleges and universities,
and mathematics instructors in secondary and higher educational institutions.
It can also be used in self-instruction as a supplement to
any standard textbook.

A picture story book for children
చీమల మీద పిల్లల కోసం ఒక చిత్ర కథ పుస్తకం
L’ouvrage que nous présentons au lecteur est rédigé sur la base
des conférences professées par l’auteur pendant les deux dernières
décennies aux étudiants de l’Université de Leningrad.
Ces dernières années l’astrophysique théorique a connu des
modifications notables. D’abord, l’ensemble des données d’observation
que doit interpréter l ’astrophysique théorique s’est extrêmement
élargi. Ceci est lié dans une grande mesure à l’apparition
et au développement rapide de la radioastronomie et de l’astrophysique
extra-atmosphérique. D’autre part, l ’astrophysique théorique
elle-même a donné naissance à plusieurs idées nouvelles importantes
sur le très grand rôle des réactions nucléaires dans l’énergétique et l’évolution des étoiles, sur l’influence considérable des forces
électromagnétiques sur l’état des atmosphères stellaires et du milieu
interstellaire, etc. En même temps, de nouvelles et puissantes
méthodes ont été élaborées dans cette discipline (en particulier, dans
la théorie de transfert du rayonnement), et les méthodes connues ont
été perfectionnées dans le but d’utiliser les moyens offerts par les
ordinateurs.
L’ouvrage présenté compte huit chapitres. Les deux premiers
traitent des problèmes de la formation du spectre continu et du
spectre de raies des étoiles. Nous y analysons en détail les processus
d’absorption et d’émission de l’énergie rayonnante qui se
déroulent dans un volume élémentaire, ainsi que les processus de
transfert de l’énergie rayonnante à travers les couches superficielles
d’une étoile. Nous montrons également comment déterminer d’après
l’observation des spectres stellaires les conditions physiques dans
les couches superficielles des étoiles et leur composition chimique.
