The Origin of Life on the Earth covers the proceedings of the First International Symposium of The Origin of Life on the Earth, held at Moscow on August 19-24, 1957. This symposium brings together numerous scientific studies on the evolutionary principles and the different stages in the evolutionary development of matter. This book is organized into seven parts encompassing 60 chapters. The first parts discuss evidence that on the formation of hydrocarbons and their derivatives on the surface of the Earth even before the emergence of life. The subsequent parts are devoted to the many asymmetrical syntheses under the influence of circularly-polarized ultraviolet light, by catalytic reactions occurring on the surface of quartz crystals, and spontaneously by slow crystallization from solutions. These topics are followed by reviews on the possible means of abiogenic formation of amino acids, porphyrins, protein-like polymers, polynucleotides and other high-molecular organic compounds. Considerable chapters explore the complete possibility of the primary formation of these compounds on the surface of the Earth even before life was present on it. Other general topics covered include nucleic acids, nucleoproteins and viruses. The last part considers general biochemical problems connected with the further development of metabolism. This book will be of value to astronomers, physicists, geologists, chemists, and biologists.

Modern Trends in Physiological Sciences, Volume 6: Aspects of the Origin of Life presents the possible ways of the chemical evolution of the Earth's surface before the origination of life. This book examines the evolutionary aspects of the biochemistry of cells and organisms. Organized into 20 chapters, this volume begins with an overview of the conditions that characterized the physical state of the Earth during the earliest periods following its formation and development. This text then examines the content of elementary oxygen as the most remarkable aspect of the Earth's atmosphere. Other chapters consider the fundamental propositions concerning the biosphere, which is regarded as important to the geochemical processes of the Earth. This book discusses as well the history of the whole substance of Earth, which determines how far abiogenic synthesis could proceed and what was the state of the Earth when life came into being. Biochemists and scientists will find this book useful.

This book is concerned with the strivings, satisfactions, hopes, and heartaches that pervade the teacher's life and work. It is based in part on a study of more than 1000 teachers and students of education.“Professor Jersild writes with disarming lucidity about many abstruse conceptions. He has the courage to discuss forthrightly important topics that are generally skirted in discussions about education. I believe that When Teachers Face Themselves will help any but the most recalcitrant reader to face himself more realistically.”—From the Foreword by Stephen M. Corey, Director, Horace Mann-Lincoln Institute of School Experimentation
