Book excerpt: From Nobel prize-winner Roger Penrose, this groundbreaking book is for anyone "who is interested in the world, how it works, and how it got here" (New York Journal of Books). Penrose presents a new perspective on three of cosmology’s essential questions: What came before the Big Bang? What is the source of order in our universe? And what cosmic future awaits us? He shows how the expected fate of our ever-accelerating and expanding universe—heat death or ultimate entropy—can actually be reinterpreted as the conditions that will begin a new “Big Bang.” He details the basic principles beneath our universe, explaining various standard and non-standard cosmological models, the fundamental role of the cosmic microwave background, the paramount significance of black holes, and other basic building blocks of contemporary physics. Intellectually thrilling and widely accessible, Cycles of Time is a welcome new contribution to our understanding of the universe from one of our greatest mathematicians and thinkers.

Book excerpt: **WINNER OF THE 2020 NOBEL PRIZE IN PHYSICS** What came before the Big Bang? How did the universe begin and must it inevitably end? In this remarkable book Roger Penrose brilliantly illuminates some of the deepest mysteries of the universe. Cycles of Time contains a penetrating analysis of the second law of thermodynamics - according to which the 'randomness' of our world is continually increasing - and a thorough examination of the light-cone geometry of space-time. It combines these two central themes to show how the expected ultimate fate of our accelerating, expanding universe can actually be reinterpreted as the 'big bang' of a new one. Presenting various standard and non-standard cosmological models, discussing black holes in depth as well as taking in the role of the cosmic microwave background along the way, Roger Penrose argues that the Big Bang was not actually the beginning of everything - nor will it signal the end. 'Science needs more people like Penrose, willing and able to point out the flaws in fashionable models from a position of authority, and to signpost alternative roads to follow' Independent

Book Synopsis Cycles of Time and Meaning in the Mexican Books of Fate by : Elizabeth Hill Boone

Download or read book Cycles of Time and Meaning in the Mexican Books of Fate written by Elizabeth Hill Boone. This book was released on 2013-05-17. Available in PDF, EPUB and Kindle. Book excerpt: In communities throughout precontact Mesoamerica, calendar priests and diviners relied on pictographic almanacs to predict the fate of newborns, to guide people in choosing marriage partners and auspicious wedding dates, to know when to plant and harvest crops, and to be successful in many of life's activities. As the Spanish colonized Mesoamerica in the sixteenth century, they made a determined effort to destroy these books, in which the Aztec and neighboring peoples recorded their understanding of the invisible world of the sacred calendar and the cosmic forces and supernaturals that adhered to time. Today, only a few of these divinatory codices survive. Visually complex, esoteric, and strikingly beautiful, painted books such as the famous Codex Borgia and Codex Borbonicus still serve as portals into the ancient Mexican calendrical systems and the cycles of time and meaning they encode. In this comprehensive study, Elizabeth Hill Boone analyzes the entire extant corpus of Mexican divinatory codices and offers a masterful explanation of the genre as a whole. She introduces the sacred, divinatory calendar and the calendar priests and diviners who owned and used the books. Boone then explains the graphic vocabulary of the calendar and its prophetic forces and describes the organizing principles that structure the codices. She shows how they form almanacs that either offer general purpose guidance or focus topically on specific aspects of life, such as birth, marriage, agriculture and rain, travel, and the forces of the planet Venus. Boone also tackles two major areas of controversy—the great narrative passage in the Codex Borgia, which she freshly interprets as a cosmic narrative of creation, and the disputed origins of the codices, which, she argues, grew out of a single religious and divinatory system.

Book excerpt: "America's constitutional system evolves through the interplay between three cycles: the rise and fall of dominant political parties, the waxing and waning of political polarization, and alternating episodes of constitutional rot and constitutional renewal. America's politics seems especially fraught today because we are nearing the end of the Republican Party's long political dominance, at the height of a long cycle of political polarization, and suffering from an advanced case of "constitutional rot." Constitutional rot is the historical process through which republics become increasingly less representative and less devoted to the common good. Caused by increasing economic inequality and loss of trust, constitutional rot seriously threatens the constitutional system. But America has been through these cycles before, and will get through them again. America is in a Second Gilded Age slowly moving toward a second Progressive Era, during which polarization will eventually recede. The same cycles shape the work of the federal courts and theories about constitutional interpretation. They explain why political parties have switched sides on judicial review not once but twice in the twentieth century. Polarization and constitutional rot alter the political supports for judicial review, make fights over judicial appointments especially bitter, and encourage constitutional hardball. The Constitution ordinarily relies on the judiciary to protect democracy and to prevent political corruption and self-entrenching behavior. But when constitutional rot is advanced, the Supreme Court is likely to be ineffective and may even make matters worse. Courts cannot save the country from constitutional rot; only political mobilization can"--
