Book Synopsis The Theory of Cosmic Grains by : N.C. Wickramasinghe
Download or read book The Theory of Cosmic Grains written by N.C. Wickramasinghe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Light scattering and absorption by small homogeneous particles can be worked-out exactly for spheres and infinite cylinders. Homogeneous particles of irregular shapes, when averaged with respect to rotation, have effects that can in general be well-approximated by reference to results for these two idealised cases. Likewise, small inhomogeneous particles have effects similar to homogeneous particles of the same average refractive index. Thus most problems can be solved to a satisfactory approximation by reference to the exact solutions for spheres and cylinders, which are fully stated here in the early part of the book. The sum of scattering and absorption, the extinction, is too large to be explained by inorganic materials, provided element abundances in the interstellar medium are not appreciably greater than solar, H 0 and NH3 being essentially excluded in the 2 general medium, otherwise very strong absorptions near 3p,m would be observed which they are not. A well-marked extinction maximum in the ultraviolet near 2200A has also not been explained satisfactorily by inorganic materials. Accurately formed graphite spheres with radii close to O.02p,m could conceivably provide an explanation of this ultraviolet feature but no convincing laboratory preparation of such spheres has ever been achieved.

Download or read book Vindication of Cosmic Biology written by Nalin Chandra Wickramasinghe and published by World Scientific. This book was released on 2015-05-28 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the year 2015, 100 years after Fred Hoyle was born, the ideas relating to the cosmic origins of life are slowly gaining credence in scientific circles. Once regarded as outrageous heresy, evidence from a variety of disciplines — astronomy, geology, biology — is converging to support these once heretical ideas. This volume opens with recent review articles pointing incontrovertibly towards our cosmic heritage, followed by a collection of published articles tracing the development of the theory throughout the years. The discovery that microorganisms — bacteria and viruses — are incredibly resistant to the harshest conditions of space, along with the detection of an estimated 144 billion habitable planets around other star systems in our galaxy alone, makes it virtually impossible to maintain that life on one planet will not interact with life elsewhere. The emerging position is that life arose exceedingly rarely, possibly only once, in the history of the cosmos, but its subsequent spread was unstoppable. "Panspermiology" can no longer be described as an eccentric doctrine, but rather is the only doctrine supported by an overwhelming body of evidence. Fred Hoyle's work in this area may in the fullness of time come to be regarded as his most important scientific contribution.

Book Synopsis Cosmology and Controversy by : Helge Kragh
Download or read book Cosmology and Controversy written by Helge Kragh and published by Princeton University Press. This book was released on 2021-03-09 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: For over three millennia, most people could understand the universe only in terms of myth, religion, and philosophy. Between 1920 and 1970, cosmology transformed into a branch of physics. With this remarkably rapid change came a theory that would finally lend empirical support to many long-held beliefs about the origins and development of the entire universe: the theory of the big bang. In this book, Helge Kragh presents the development of scientific cosmology for the first time as a historical event, one that embroiled many famous scientists in a controversy over the very notion of an evolving universe with a beginning in time. In rich detail he examines how the big-bang theory drew inspiration from and eventually triumphed over rival views, mainly the steady-state theory and its concept of a stationary universe of infinite age. In the 1920s, Alexander Friedmann and Georges Lemaître showed that Einstein's general relativity equations possessed solutions for a universe expanding in time. Kragh follows the story from here, showing how the big-bang theory evolved, from Edwin Hubble's observation that most galaxies are receding from us, to the discovery of the cosmic microwave background radiation. Sir Fred Hoyle proposed instead the steady-state theory, a model of dynamic equilibrium involving the continuous creation of matter throughout the universe. Although today it is generally accepted that the universe started some ten billion years ago in a big bang, many readers may not fully realize that this standard view owed much of its formation to the steady-state theory. By exploring the similarities and tensions between the theories, Kragh provides the reader with indispensable background for understanding much of today's commentary about our universe.
Book Synopsis Diseases From Outer Space - Our Cosmic Destiny (Second Edition) by : Fred Hoyle
Download or read book Diseases From Outer Space - Our Cosmic Destiny (Second Edition) written by Fred Hoyle and published by World Scientific. This book was released on 2020-07-17 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of the monumental book Diseases from Space by Sir Fred Hoyle and N Chandra Wickramasinghe appeared some 40 years ago, encapsulating the key principles of Panspermia, and it has been the guiding principle in the new scientific field of Astrobiology.This latest edition, revised and expanded by Chandra Wickamasinghe, continues to describe the consequences of the theory of cometary panspermia that relate to the origins of epidemic disease. Available data on historic and modern plagues are analysed to show that extraterrestrial bacteria and viruses are the cause of ongoing pandemics of diseases.Adherence to an inappropriate and obsolete theory of pandemics could put in jeopardy the economic well-being of the entire world, perhaps even threatening the continued existence of our civilization.
Book Synopsis A Journey with Fred Hoyle by : Chandra Wickramasinghe
Download or read book A Journey with Fred Hoyle written by Chandra Wickramasinghe and published by World Scientific. This book was released on 2013 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the story of the author''s unique scientific journey with one of the most remarkable men of 20th century science. The journey begins in Sri Lanka, the author''s native country, with his childhood acquaintance with Fred Hoyle''s writings. The action then moves to Cambridge, where the famous HoyleOCoWickramasinghe collaborations begin. A research programme which was started in 1962 on the carbonaceous nature of interstellar dust leads, over the next two decades, to developments that are continued in both Cambridge and Cardiff. These developments prompt Hoyle and the author to postulate the organic theory of cosmic dust (which is now generally accepted), and then to challenge one of the most cherished paradigms of contemporary science OCo the theory that life originated on Earth in a warm primordial soup.This new edition examines the many scientific developments that have transpired since the first edition was published. The discovery of bacteria in the upper reaches of the atmosphere, biological signatures in meteorites, spectroscopy of high-z galaxies and more all mesh with many of the ideas that had their origin in the first edition. Pushing into the future, the updated text examines the many experiments and probes currently operating or planned that will shed more light on the theory of planetary panspermia. A Journey with Fred Hoyle is an intriguing book that delineates the progress of a collaboration spanning 40 years, through a sequence of personal reflections, anecdotes and reminiscences.

Download or read book A Great Man of Science written by Francis A. Andrew and published by Trafford Publishing. This book was released on 2015-09-22 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Francis Andrew has completed a monumental ten year task of writing appraisals on all of the published works of the late Sir Fred Hoyle. It is truly a worthwhile accomplishment as all of Hoyles books are now out of print. Francis Andrews work therefore offers a great service in preserving the thoughts of one the twentieth centurys greatest minds. Gihan, Weerasekara. Dompe, Sri Lanka. A Great Man of Great Science covers all of Sir Fred Hoyles publications from his fi rst in 1950 to his last in 2001. Francis Andrews appraisal of each of these works is the next best thing to reading the original works of Hoyle himself. After reading these appraisals, one could well be tempted to take the next step and read the actual works of Hoyle. Siddhant Bahuguna. Uttar Pradesh, India. Francis A. Andrew has truly done a magnificent job in writing appraisals for each of Sir Fred Hoyles works. As Francis style of writing has done so much to make Hoyle come alive and inject into his works a relevancy for the twenty fi rst century, so it would be that even if readers of this volume were unacquainted with any of Hoyles books, they would surely be tempted to procure for themselves the original works of Hoyle.

Book Synopsis Dust In The Universe: Similarities And Differences by : K S Krishna Swamy
Download or read book Dust In The Universe: Similarities And Differences written by K S Krishna Swamy and published by World Scientific. This book was released on 2005-06-08 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of dust in the universe is an exciting area in current astronomy. Dust formed during an earlier epoch could be different from that formed at a later time, but the nature and composition of dust is not presently understood in its entirety. The comprehensive study presented in this book provides a much needed critical analysis of different types of dust in the universe. The information derived from presolar grains from comets, meteorites and interplanetary dust particles as well as the relevant laboratory studies are discussed. This should help in our goal of understanding the evolution of dust with cosmic time.

Wickramasinghe and Hoyle's picture of a galaxy teeming with life is a stunning one … The scientific community has come a long way towards Hoyle and Wickramasinghe's position, wholeheartedly embracing the idea of planetary panspermia." New Scientist "… An enlightening account of a 40-year scientific collaboration between two remarkable men." Lord Rees OM, Astronomer Royal "The Hoyle-Wickramasinghe collaboration was notable for the daring leaps over knowledge gaps they were prepared to make. This book is a valuable guide to their corpus, and can serve as a source of ideas and speculations." International Journal of Astrobiology "A Journey with Fred Hoyle is an intriguing, pacey insight into the working of a fertile scientific mind, and especially one focussed on a topic that is not in the mainstream of astronomical and biological endeavour … I enjoyed A Journey with Fred Hoyle greatly." The Observatory Magazine "This is a fine blend of personal anecdotes, travel impressions, and scientific reporting — interesting, informative, and worth reading."

Book Synopsis Ultraviolet Astronomy and the Quest for the Origin of Life by : Ana I. Gomez de Castro
Download or read book Ultraviolet Astronomy and the Quest for the Origin of Life written by Ana I. Gomez de Castro and published by Elsevier. This book was released on 2021-03-27 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultraviolet Astronomy and the Quest for the Origin of Life addresses the use of astronomical observations in the ultraviolet range to better understand the generation of complex, life-precursor molecules. The origin of RNA is still under debate but seems to be related to the generation of pools of complex organic molecules submitted to heavy cycles of solution in water and drying. This book investigates whether these cycles require a planetary surface or may occur in space by examining both the theoretical and observational aspects of the role of UV radiation in the origin of life. This book offers the latest advances in these studies for astronomers, astrobiologists and planetary scientists. Addresses both the theoretical and observational aspects of the role of Ultraviolet (UV) radiation in the origin of life Builds on the requirements to produce prebiotic molecules in space and the implications for the origin of RNA Investigates the use of ultraviolet observations related to planetary system formation, the evolution of young planetary disks, and the interaction of stars with planetary atmospheres
Book Synopsis Eight Preposterous Propositions by : Robert Ehrlich
Download or read book Eight Preposterous Propositions written by Robert Ehrlich and published by Princeton University Press. This book was released on 2021-04-13 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Placebo cures. Global warming. Extraterrestrial life. Psychokinesis. In a time when scientific claims can sound as strange as science fiction--and can have a profound effect on individual life or public policy--assessing the merits of a far-out, supposedly scientific idea can be as difficult as it is urgent. Into the breach between helpless gullibility and unyielding skepticism steps physicist Robert Ehrlich, with an indispensable guide to making sense of "scientific" claims. A series of case studies of some of the most controversial (and for the judging public, deeply vexing) topics in the natural and social sciences, Ehrlich's book serves as a primer for evaluating the evidence for the sort of strange-sounding ideas that can shape our lives. A much-anticipated follow-up to his popular Nine Crazy Ideas in Science, this book takes up issues close to readers' everyday reality--issues such as global warming, the dangers of cholesterol, and the effectiveness of placebos--as well as questions that resonate through (and beyond) civic life: Is intelligent design a scientific alternative to evolution? Is homosexuality primarily innate? Are people getting smarter or dumber? In each case, Ehrlich shows readers how to use the tools of science to judge the accuracy of strange ideas and the trustworthiness of ubiquitous "experts." As entertaining as it is instructive, his book will make the work of living wisely a bit easier and more reliable for scientists and nonscientists alike.
