13.8 : the quest to find the true age of the universe and the theory of everything by Gribbin, John, 1946- author instant download
1 online resource (xiii, 242 pages, 16 unnumbered pages of plates) :, The twentieth century gave us two great theories of physics. The general theory of relativity describes the behavior of very large things, and quantum theory the behavior of very small things. In this landmark book, John Gribbin--one of the best-known science writers of the past thirty years--presents his own version of the Holy Grail of physics, the search that has been going on for decades to find a unified \"Theory of Everything\" that combines these ideas into one mathematical package, a single equation that could be printed on a T-shirt, containing the answer to life, the Universe, and everything. With his inimitable mixture of science, history, and biography, Gribbin shows how--despite skepticism among many physicists--these two great theories are very compatible, and point to a deep truth about the nature of our existence. The answer lies, intriguingly, with the age of the universe: 13.8 billion years, Includes bibliographical references (pages 233-234) and index, Introduction: The Most Important Fact; Part Zero: Prologue; 2.712 -- Taking the temperature of the Universe; Part One: How Do We Know the Ages of Stars?; 1 2.898 -- Prehistory: Spectra and the nature of stars; Locating lines; Hunting helium; Hunting hydrogen; The heat of the Sun; The heat of the stars; The heat inside; 2 0.008 -- At the heart of the Sun; A French connection; No free lunch; Seats of enormous energies; A hotter place?; A quantum of solace; 3 7.65 -- Making 'metals'; Cycles and chains of fusion, Rocks of ages; From the Bomb to the stars; The last should be first; Stardust; 4 13.2 -- The ages of stars; Hertzsprung, Russell and the diagram; Ashes to ashes; Globular cluster ages; White dwarf ages; Radiometric ages and the oldest known star; Part Two: How Do We Know the Age of the Universe?; 5 31.415 -- Prehistory: Galaxies and the Universe at large; The power of pure reason; One step forward, two steps back; Nebular…
