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.
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.

Book excerpt: Discoveries In Astronomy And Astrophysics Have Brought Out Several Outstanding Problems And Puzzles. For Resolving These New Inputs From Physics May Be Required. There Exist Several Centers With Excellent Instruments And Many New Instruments Will Be Developed In The Next Few Years. Similarly Several Satellites Are In Orbit And More Are Being Planned For Future Astronomical Studies. Clearly Astronomy And Astrophysics Will Provide Great Opportunities For An Inquisitive Mind To Do First Rate Research Work.There Is A Good Scope For Carrying Out Path Breaking Work In Astronomy, Astrophysics And Space Sciences. To Attract Students And Researchers To This Exciting Frontier, It Is Necessary To Provide Them A Strong Academic Foundation. Astrophysics: A Modern Perspective Is An Attempt In This Direction. This Book Has Evolved Out Of A Series Of Lectures Delivered At Two Winter Schools In Astronomy And Astrophysics Organized By The Tata Institute Of Fundamental Research (Tifr), Bombay. Special Effort Has Been Made To Highlight Some Of The Challenging And Unsolved Problems From The Observational And Theoretical Points Of View.All The Contributors To This Volume Are Well Known Scientists Of Tifr And Have Made Significant And Lasting Contributions In Their Respective Fields. Each Chapter Develops The Subject From Basic Considerations Of Physics And Goes On To The Present Day Understanding. Some Of The Important Problems Facing Astronomers And Astrophysicists Today Are Highlighted Throughout The Book. The Close Interaction Between Astronomers, Astrophysicists And Physicists Has Also Been Brought Out. It Is Hoped That This Approach Will Attract More Students And Research Workers To The Fascinating Area Of Astronomy And Astrophysics.

Book Synopsis A Great Man of Science by : Francis A. Andrew
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.

Book Synopsis Vindication Of Cosmic Biology: Tribute To Sir Fred Hoyle (1915-2001) by : Nalin Chandra Wickramasinghe
Download or read book Vindication Of Cosmic Biology: Tribute To Sir Fred Hoyle (1915-2001) written by Nalin Chandra Wickramasinghe and published by World Scientific. This book was released on 2015-05-28 with total page 713 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.
