A vivid, up-to-date tour of the Earth's last frontier, a remote and mysterious realm that nonetheless lies close to the heart of even the most land-locked reader. The sea covers seven-tenths of the Earth, but we have mapped only a small percentage of it. The sea contains millions of species of animals and plants, but we have identified only a few thousand of them. The sea controls our planet's climate, but we do not really understand how. The sea is still the frontier, and yet it seems so familiar that we sometimes forget how little we know about it. Just as we are poised on the verge of exploiting the sea on an unprecedented scale-mining it, fertilizing it, fishing it out-this book reminds us of how much we have yet to learn. More than that, it chronicles the knowledge explosion that has transformed our view of the sea in just the past few decades, and made it a far more interesting and accessible place. From the Big Bang to that far-off future time, two billion years from now, when our planet will be a waterless rock; from the lush crowds of life at seafloor hot springs to the invisible, jewel-like plants that float at the sea surface; from the restless shifting of the tectonic plates to the majestic sweep of the ocean currents, Kunzig's clear and lyrical prose transports us to the ends of the Earth.
From the inventor of the PalmPilot comes a new and compelling
theory of intelligence, brain function, and the future of
intelligent machines

Global Warming is a serious matter requiring an open and honest discussion. Unfortunately, I have not seen any such discussion. I hear that there is consensus among scientists. When they know what they are talking about, they also are able to explain what they have discovered. In this topic, though, whoever these scientists are, they do not seem willing to come forward to do the explanation, instead politicians are the ones who do the talking. In addition, there are also rumors going around that the information collected regarding the issue of Global Warming appears to be tainted.This book not only contains scientific information which has been approved for a long time, it also makes this information easy for everyone to understand and recognize. Many of the phenomena we see every day have been studied and measured thoroughly, yet because we are not able to stop these phenomena from happening, we avoid trying to understand why they occur, and in some cases, we just legitimize our guessing.The accurate data collected by legitimate sources are used and presented in this book, and when the correct explanation is presented, it is easy to understand that the whole explanation is simple.The statements presented are clear and simple, and it is not the author who has collected the information, yet all are based on a proven science which is being used in many industries and for a long time.Once you recognize that these topics are simple, you can begin to have a serious discussion in your own circle, and feel free to scrutinize this author.
The Practice of Technical and Scientific Communication is a detailed description of the work done by technical and scientific communicators in a variety of professional settings. It is designed mainly as an educational and career planning tool for students preparing for careers in technical communication. However, it may also be used by educators who teach and advise students, by researchers who need a comprehensive picture of technical communication practice, and by employers who need a more thorough understanding of how technical communicators can contribute to their businesses.
Hepatitis C and Dengue viruses belong to the family of Flaviviridae. Viruses in this family are enveloped, have positive-sense RNA and are responsible for a variety of life threatening diseases. Hepatitis C virus is the major etiological agent of post-transfusion hepatitis worldwide. An estimated 3 % of the world's population is infected with HCV according to the World Health Organization. Infection with HCV will most regularly result in chronic hepatitis, which leads to liver cirrhosis, hepatocellular carcinoma and liver failure. Dengue is currently the most important viral disease transmitted by mosquitoes afflicting humans the world context. Clinical symptoms range from mild fevers to a severe haemorrhagic disease. To date neither specific antiviral treatments exist nor are there any vaccines available for both infections. Thus there is an urgent need for new therapies.
This book contains articles based on oral and poster presentations at the 17th International Symposium on Flavins and Flavoproteins, which was held July 24-29, 2011 at the University of California Berkeley in the USA. These triennial conferences highlight the latest advances in the field and the conference proceedings book serves both as documentation of the event and as a reference.
Genetics is one of the most powerful scientific fields today. It is transforming how we view medicine and public health, and is producing tremendous new discoveries in biotechnology. Advances in genetics also provoke extensive ethical debates over cloning, genetic counseling, stem cell research, and privacy. But to understand these debates, it's essential to understand where these ideas came from - the ideas of the past have had tremendous influence on not just the science of genetics, but on the political and ethical debates surrounding the field. This volume in the Greenwood Guides to Great Ideas in Science series provides an accessible and thorough description of the history of genetics, and includes relevant historical ideas from the Classical era to the present day. The Gene: A Historical Perspective provides an overview of the field of genetics, with contemporary examples of its scientific, social and economic importance, and an emphasis on the historical development of the concept of the gene, such as: Ancient and medieval ideas of the nature of generation and inheritance BLThe Mendelian revolution and the discovery of the laws of inheritance The chromosomal theory of inheritance, and the "fly lab" of Thomas Hunt Morgan BLMolecular biology and the discovery of the structure of DNA by Watson and Crick BLThe Human Genome Project The book includes a glossary of terms, a timeline of events, and a bibliography of accessible resources for students who wish to learn more about the gene.
AND Their Effects byHARLAN TRUE STETSON Research Associate at the Massachusetts Institute of Technology Author of B STARS AND THE STAJLS Yorfc WHITTLESEY HOUSE London MCGRAW-HILL BOOK COMPANY, INC. of and trireless i t tie cii Sciilt field of solar - t erTes trial FOREWARNING THE near approach of another sunspot maximum with the accompanying interest shown by the press and the general public gives the occasion for a book on sunspot s. So much has been said about the possibilities of sunspots affecting the earth and human affairs that a candid discussion of sunspots and their effects is due the general reader who would keep himself informed of trends in science. Sunspots have been blamed for calamities and misfortunes that run the gamut from Florida hurricanes to financial panics. Is there any basis whatever for such assumptions Since we are all more interested in ourselves than we are in things, the book has been written from the human point of view. While statements have been qualified, various possible hypotheses have been dis cussed which bear upon the question of solar dis turbances and affairs on the earth. Perhaps all too long has the reading public been dependent upon the technical material in textbooks on astronomy for a knowledge of sunspots. Such textbooks which must deal only with well-established facts cannot naturally try to discuss speculative questions. This book therefore departs from the usual type of book on science in that it frankly presents questionable material as well as the results of more completely Forewarning established facts from which the reader may draw his own conclusions with respect to inferences not yet fully established as weU as to those which may beregarded as beyond debate. As the book is intended to be distinctly popular, the more speculative material which intrigues the imagination has been presented in the earlier part, leaving the more well-established effects of sunspots upon the earth to the later chapters. The book undoubtedly raises more questions than it answers, and will, it is hoped, suggest attention to some of the less conventional aspects of the question concerning the influence of the sunspots on world events. So many apparently serious articles have been written concerning sunspots and the business cycle that a chapter is devoted to the more plausible hypoth eses that may be worth investigation If the author appears noncommittal in his interpretation of some of the more startling presentations, it is because a scientist cannot by nature be otherwise. On the other hand, I have refrained from condemning interpretations where evidence is still scanty, for thus to condemn appears to me as unscientific as to make positive statements where complete evidence is wanting. If the book falls into the hands of the overcredulous, perhaps a word of warning is necessary to curb hurried conclusions. One can only hope that none of the more speculative statements will be quoted except with qualifications which go therewith. Forewarning In the closing chapter I have endeavored to differ entiate clearly between the several effects well established and scientifically recognised from those which are more speculative and require much further investi gation before definite conclusions can be drawn. Only by such differentiation can the whole subject be clarified with the door still open for future progress. A scientific reader will misstechnical phraseology and numerous references quoting sources which obvi ously are out of place in so popular a presentation. If the reading of the book stimulates a consciousness of mans cosmic surroundings and opens certain ques tions for serious consideration, the answers to which are yet to come, the purpose of the book will in a meas ure be realized.

The Yearbook addresses the overriding question: what are the effects of the 'opening up' of science to the media? Theoretical considerations and a host of empirical studies covering different configurations provide an in-depth analysis of the sciences' media connection and its repercussions on science itself. They help to form a sound judgement on this recent development.
As children, we are captivated by stories of huge, fantastical creatures, such as the wooly mammoth and the pterodactyl. The prevailing wisdom is these species are long extinct, but new evidence uncovered by author Gerald McIsaac casts doubt on these widely held assumptions. McIsaac gathered stories from the elders of the First Nation-those who were formerly referred to as Indians, Native Americans, or Aboriginals. First Nation elders provided McIsaac with detailed descriptions of six species long thought to be extinct. These species include the "Devil Bird," the "Hairy Elephant," the "Wilderness Wolf," the "Rubber-Faced Bear," the "Lake Monster," and "Sasquatch." In Bird from Hell, McIsaac separates fact from fiction by comparing eyewitness accounts of these species with scientific opinion concerning their identity. His conclusion is that these huge species are not extinct, but he needs assistance in gathering evidence to substantiate this claim. By following the simple directions provided in Bird from Hell, you can help prove these various species still exist.
There is hardly a technical library in the world in which the volumes of the Chemical Formulary (Volumes 1-34) do not occupy a prominent place. Chemists both experienced and beginner, continually refer to them. It does not duplicate any of the formulas included in previous volumes, but lists a wide array of modern and salable products from all branches of the chemical industries. An excellent reference for formulation problems. -CONTENTS - I. Introduction - II. Adhesives - III. Coatings - IV. Cosmetics - V. Detergents and Disinfectants - VI. Drug Products - VII. Elastomers, Plastics and Resins - VIII. Foods and Beverages - IX. Polishes - X. Textile Specialties - XI. Miscellaneous - Appendix - Index - PREFACE - Chemistry, as taught in our schools and colleges, concerns chiefly synthesis, analysis, and engineering-and properly so. It is part of the right foundation for the education of the chemist. Many a chemist entering an Industry soon finds that most of the products manufactured by his concern are not synthetic or definite complex compounds, but are mixtures, blends, or highly complex compounds of which he knows little or nothing. The literature in this field, if any, may be meager, scattered, or obsolete. Even chemists with years of experience In one or more Industries spend considerable time and effort in acquainting themselves with any new field which they may enter. Consulting chemists similarly have to solve problems brought to them from industries foreign to them. There was a definite need for an up-to-date compilation of formulae for chemical compounding and treatment. Since the fields to be covered are many and varied, an editorial board of chemists and engineers engaged in many industries was formed. Many publications, laboratories, manufacturing firms, and Individuals have been consulted to obtain the latest and best information. It is felt that the formulas given in this volume will save chemists and allied workers much time and effort. Manufacturers and sellers of chemicals will find, In these formulae, new uses for their products. Non-chemical executives, professional men, and Interested laymen will make through this volume a "speaking acquaintance" with products which they may be using, trying or selling. It often happens that two Individuals using the same Ingredients in the same formula get different results. This may be due to slight deviations in the raw materials or unfamiliarity with the intricacies of a new technique. Accordingly, repeated experiments may be necessary to get the best results. Although many of the formulas given are being used commercially, many have been taken from the literature and may be subject to various errors and omissions. This should be taken into consideration. Wherever possible, it is advisable to consult with other chemists or technical workers regarding commercial production.
Cancer Medicine: Drug Discovery and Development, is an essential text in the science which bridges the gap between laboratory and bedside medicine. The typical cancer medicine text book discusses pathology and treatment of neoplasms. This book takes an entirely different approach, and while it briefly describes certain neoplasms, it focuses on the discovery and development of anticancer agents. It details the procurement of plant materials from various remote parts of the earth, such as Africa, their extraction processes, application into animal cancer models and further development in human clinical trials. Novel research methods are discussed, and while this book does not assert itself as a terminal text, it challenges the young and older scientists to a path of medicinal creativity, especailly in its area of focus (cancer), where further research and discoveries are desperately needed. Furthermore, it serves as a guide of further inquiry into the discovery and development of pharmaceutical agents for challenging parasitic infections, such as malaria, and viral ailments such as HIV-AIDS.
This book confronts humanity with God's ID (Intelligent Design) of the universe and the design of man, himself. The confirmation is the creation. The universe is the proof of the truth. The Bible is the revelatory declaration. Jesus Christ is the manifestation. Man cannot truthfully and successfully deny the overwhelming reality of God without plunging himself into a fantasy world of perplexing confusion and insanity. The graphics of law, art, religion and science are used to help man in the late date of the 21st Century to get beyond his irrational and infantile denial of God in the face of invincible evidence and infallible proof. Man's denial of God and rebellion against God is a vain self pride and irrational denial of the foundation of his own existence. In view of humanity's escalating lethal cultural crises, can the world afford the anti-God, anti-Christ, anti-Bible and anti-truth spirits in a GPS laden globalized nuclear and other weapons of mass destruction world?
Text extracted from opening pages of book: SCIENTIFIC MEMOIRS EDITED BY J. S. AMES, PH. D. PROFESSOR OP PHYSICS IN JOHNS HOPKINS UNIVERSITY VIII. THE EFFECTS OF A MAGNETIC FIELD ON RADIATION THE EFFECTS OF A MAGNETIC FIELD ON RADIATION MEMOIRS BY FARADAY, KERR AND ZEEMAN EDITED BY E. P. LEWIS, PH. D. NEW YORK .: CINCINNATI: CHICAGO AMERICAN BOOK COMPANY COPYRIGHT, 1900, BY AMERICAN BOOK COMPANY. W. P. I PBEFACE Historical IN the early part of this century possible relationships between the various forces of nature began to attract the attention of physicists. In 1800 William Herschel discovered that a heat spectrum is superimposed on and extends be yond the visible solar spectrum, indicating some relationship between heat and light. This seems to have suggested to Domenico Morichini, of Kome, the search for a relationship between light and magnetism. In 1812 he claimed that he had been able to magnetize steel needles by exposing them to the violet radiation in the solar spectrum. Others, including Mrs. Somemlle, in England, believed that they had verified his results, but many wore unable to reproduce them, and it was finally demonstrated that all these effects had been due to other causes. The dispute over this question extended over many years, and is an instructive illustration of the difficulty which even skilled experimenters may have in solving a com paratively simple experimental problem. About 1825 Sir John Herschel sent a polarized beam of light along the axis of a helix carrying an electric current. Exami nation with an analyzer showed no effect. He also intended to test the effect of a polarized beam passing tangentially by a con ductor carrying a current, but never executedthe experiment. No other attempt to show a relationship between light and magnetism seems to have been made until Faraday undertook the investigation described in the following pages. Theoretical In the Proceedings of the Royal Society for June, 1856, Sir William Thomson wrote: The magnetic influence on light PREFACE discovered by Faraday depends on the direction of motion of moving particles. For instance, in a medium possessing it, particles in a straight line parallel to the lines of magnetic force, displaced to a helix round this line as axis, and then projected tangentially with such velocities as to describe circles, will have different velocities according as their mo tions are round in one direction ( the same as the nominal direction of the galvanic current in the magnetizing coil) or in the contrary direction. But the elastic reaction of the medium, must be the same for the same displacements, what ever be the velocities ami directions of the particles; that is to say, the forces which are balanced by centrifugal force of the circular motions are equal, while the luminiferous motions are unequal. The absolute circular motions being, therefore, either equal, or such as to transmit equal centrifugal forces to the particles initially considered, it follows that the luminife rous motions are only components of the whole motion; ami that a less luminiferous component in one direction, com pounded with a motion existing in the medium when trans mitting no light, gives an equal resultant to that of a greater luminiferous motion in the contrary direction, compounded with the same non-luminous motion. Maxwell, in his Electricity and Magnetism, , vol. ii., chap, xxi, offers thefollowing partial physical explanation as an exten sion of the above remarks: * It is a well-known theorem in kinematics that two uniform circular vibrations, of the same amplitude, having the same periodic time, and in the same plane, but revolving in opposite directions, are equivalent, when compounded together, to a rectilinear vibration. The periodic time of this vibration is equal to that of the circular vibrations, its amplitude is double, and its direction is in the line joining the points at which two particles, describing the circular vibrations in opposite dire
This book explains the influence of damping on the ride and handling of race and sports cars. The author deals with the myths about damping, explaining the correllation between laws of physics and damping design, showing that there is nothing myterious about the way dampers work or damping forces can be manipulated. If the tire is the most important part transmitting engine power to the pavement, an integrated damping/suspension system is the second most important component between engine power and road surface. Over the last decades, suspension design and tuning has become one of the most important reasons for success on the race track. One of the most significant achievements of the author has been the realisation that the unsprung mass is a greater disturbing factor for good handling than the sprung mass of a car. The author describes the observations leading to this breakthrough in modern suspension tuning and the excellent results in racing. |
