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 WeinsteinCredits to the original uploaders for the scans, this is a cleaned optimised scan.Thanks to A.
