This book was released on 2012-12-06 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: At about the time I was a student in the 1930's, it had become increasingly evident that all the elements existing on the Earth today had already been discovered. Scientists then began "discovering" new elements by means of their artificial synthesis and some of the man-made elements found important military as well as industrial applications. I have often wondered, however, if the importance of these artificial elements may not have been overly emphasized by contemporary scientists for their practical applications. It seemed to me that these man-made elements were destined to play an important role du ring the second half of the 20th century in the study of the origin of the elements in the Universe. This subject of study, which dates back to the days of ancient Greek philoso phers, may be regarded as the most fundamental in the entire compass of our modetn science. Since I joined the faculty of the University of Arkansas in the early 1950's, I have had the good fortune of being able to maintain a long-range research project, the ultimate goal of which was to elucidate the origin of the elements. I have presented the results from these and related investigations on numerous occasions. While serving as a tour speaker of the American Chemical Society for many years, I have had the privilege of visiting many ofthe local sections to present a lecture on the origin ofthe elements.

Available in PDF, EPUB and Kindle. Book excerpt: What do we mean by a chemical element? A chemical element is matter, all of whose atoms are alike in having the same positive charge on the nucleus and the same number of extra-nuclear electrons. As we shall see in the following elemental review, the origin of the chemical elements show a wide diversity with some of these elements having an origin in antiquity, other elements having been discovered within the past few hundred years and still others have been synthesized within the past fifty years via nuclear reactions on heavy elements since these other elements are unstable and radioactive and do not exist in nature.

Book excerpt: Based on an American Chemical Society Symposium organized by Professors Glenn Seaborg and Oliver Manuel, this volume provides a comprehensive record of different views on this important subject at the end of the 20th century. They have assembled a blend of highly respected experimentalists and theorists from astronomy, geology, meteoritics, planetology and nuclear chemistry and physics to discuss the origin of elements in the solar system. The intent was to include all points of view and let history judge their validity.
Download or read book No Free Lunch written by William A. Dembski and published by Rowman & Littlefield. This book was released on 2006-11 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: Darwin's greatest accomplishment was to show how life might be explained as the result of natural selection. But does Darwin's theory mean that life was unintended? William A. Dembski argues that it does not. As the leading proponent of intelligent design, Dembski reveals a designer capable of originating the complexity and specificity found throughout the cosmos. Scientists and theologians alike will find this book of interest as it brings the question of creation firmly into the realm of scientific debate. The paperback is updated with a new Preface by the author.

Available in PDF, EPUB and Kindle. Book excerpt: If extinctions are part of nature’s course, then why does it matter that so many species are becoming extinct now? Over the long course of man’s occupance on Earth has been seemingly characterised by its dependence on nature and the ecology which has overtime greatly influenced homeostatic regulation – i.e. balance of nature, where clearly, nature's capacity to support man’s existence has plummeted with the release of obnoxious chemicals into the environment. It is pertinent to note that all species, while evolving and adapting to the demands of their habitats or modernization exigencies, changes dramatically, subjecting the ecologies, which happen to be the fabric of life to the dynamic swirl of physical forces and of rapid decline of species diversity. If we continue to lose large and vital portions of the natural world to extinction of species and other criticalities, we humans would be able to cope, but plants and animals may not be able to adapt to most of these changes, and as a result may die and become extinct, resulting in a break in food chain. A considerable attempt has been made through this book to explicitly cover these emerging concerns or topics, in a consolidated form which will provide effective understanding of environmental problems currently being faced in different world regions and perhaps not just to give the reader a fair knowledge about the huge role the ecology has in the survival of species and existence of man, but to provide the extent to which the state of dynamic equilibrium from nature will deprive the generations yet unborn the right to clean and healthy environment and harmony with nature.

Download or read book The Chemistry of the Actinide and Transactinide Elements Set Vol 1 6 written by L.R. Morss and published by Springer Science & Business Media. This book was released on 2010-10-21 with total page 4511 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fourth edition of "The Chemistry of the Actinide and Transactinide Elements" comprises all chapters in volumes 1 through 5 of the third edition (published in 2006) plus a new volume 6. To remain consistent with the plan of the first edition, “ ... to provide a comprehensive and uniform treatment of the chemistry of the actinide [and transactinide] elements for both the nuclear technologist and the inorganic and physical chemist,” and to be consistent with the maturity of the field, the fourth edition is organized in three parts. The first group of chapters follows the format of the first and second editions with chapters on individual elements or groups of elements that describe and interpret their chemical properties. A chapter on the chemical properties of the transactinide elements follows. The second group, chapters 15-26, summarizes and correlates physical and chemical properties that are in general unique to the actinide elements, because most of these elements contain partially-filled shells of 5f electrons whether present as isolated atoms or ions, as metals, as compounds, or as ions in solution. The third group, chapters 27-39, focuses on specialized topics that encompass contemporary fields related to actinides in the environment, in the human body, and in storage or wastes. Two appendices at the end of volume 5 tabulate important nuclear properties of all actinide and transactinide isotopes. Volume 6 (Chapters 32 through 39) consists of new chapters that focus on actinide species in the environment, actinide waste forms, nuclear fuels, analytical chemistry of plutonium, actinide chalcogenide and hydrothermal synthesis of actinide compounds. The subject and author indices and list of contributors encompass all six volumes.

Download or read book Molecular Theory of Evolution written by Bernd-Olaf Küppers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of this book is the physico-chemical theory of the origin of life. Although this theory is still in statu nascendi, it has been developed in recent years to the point where a coherent presentation is possible. The book is intended as an introductory text for students of physics, chemistry or biology. This interdisciplinary aim has necessitated a choice of material based on the lowest common denominator of physicists and biologists. In particular, the predominantly mathematical and biological sections have been presented at the most elementary l.evel possible. The less mathematically inclined reader can omit Sections (5.3)-(5.5), (5.7)-(5.10), (6.2), (6.3), (9.1)-(9.3), (12.1) and (13.3) without losing the overall view. For critical reading of the manuscript, for discussions and for many useful suggestions I wish to thank M. Eigen (Gottingen), w.e. Gardiner (Austin), D. Porschke (Gottingen), P. Schuster (Vienna), P.R. Wills (Auckland) and P. Woolley (Berlin). The translation of the original, German manuscript into English was kindly undertaken by Paul Woolley. During this and subsequent stages of revision he introduced a great many improvements in the text and the presentation of material. My particular thanks are due to him for his decisive contribution to this book. Last of all I wish to thank Ingeborg Lechten for typing the text in its various stages of evolution. The completion of this book is largely to be attributed to her patience and efficiency.

Available in PDF, EPUB and Kindle. Book excerpt: John Emsley's Nature's Building Blocks was published in paperback in 2003. In this readable, informative, and fascinating guide to the elements are entries on each of the 100-odd chemical elements, arranged alphabetically from actinium to zirconium. Each entry comprises an explanation of where the element's name comes from, followed by Body element (the role it plays in living things), Element of history (how and when it was discovered), Economic element (what it is used for), Environmental element (where it occurs, how much), Chemical element (facts, figures, and narrative), and Element of surprise (an amazing, little-known fact). Since publication of the first edition there have been a number of developments. Three new chemical elements have been named and validated: darmstadtium, roetgenium, and copernicium and the section on 'transfermium elements' has now been incorporated into the main part of the book. Economic uses of elements have grown, and some quite rare elements such as Scandium are now economically important, along with updates to elements such as gold due to new roles in industry. Fully revised and updated for 2010, this browsable compendium holds a wealth of useful information.
