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 Astromineralogy written by Thomas Henning and published by Springer Science & Business Media. This book was released on 2010-09-21 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astromineralogy deals with the science of gathering mineralogical information from the astronomical spectroscopy of asteroids, comets and dust in the circumstellar environments in general. This field has received a tremendous boost with the reliable identification of minerals by the Infrared Space Observatory. The first edition of this book, published in 2003, was the first comprehensive and coherent account of this exciting field. Data obtained in the meantime with the Spitzer Infrared Space Telescope, the stardust mission to the comet 81P / Wild 2, and with the Cassini mission, together with progress in ground-based observations and laboratory astrophysics form the basis for this updated and widely extended second edition.Beyond addressing the specialist in the field, the book is intended as a high-level but readable introduction to astromineralogy for both the nonspecialist researcher and the advanced student.

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.

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 162 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.
