The Universe Unraveling

During the Eisenhower and Kennedy administrations, Laos was positioned to become a major front in the Cold War. Yet American policymakers ultimately chose to resist communism in neighboring South Vietnam instead. Two generations of historians have explained this decision by citing logistical considerations. Laos's landlocked, mountainous terrain, they hold, made the kingdom an unpropitious place to fight, while South Vietnam—possessing a long coastline, navigable rivers, and all-weather roads—better accommodated America's military forces. The Universe Unraveling is a provocative reinterpretation of U.S.-Laos relations in the years leading up to the Vietnam War. Seth Jacobs argues that Laos boasted several advantages over South Vietnam as a battlefield, notably its thousand-mile border with Thailand, whose leader was willing to allow Washington to use his nation as a base from which to attack the communist Pathet Lao.More significant in determining U.S. policy in Southeast Asia than strategic appraisals of the Laotian landscape were cultural perceptions of the Lao people. Jacobs contends that U.S. policy toward Laos under Eisenhower and Kennedy cannot be understood apart from the traits Americans ascribed to their Lao allies. Drawing on diplomatic correspondence and the work of iconic figures like "celebrity saint" Tom Dooley, Jacobs finds that the characteristics American statesmen and the American media attributed to the Lao—laziness, immaturity, and cowardice—differed from the traits assigned the South Vietnamese, making Lao chances of withstanding communist aggression appear dubious. The Universe Unraveling combines diplomatic, cultural, and military history to provide a new perspective on how prejudice can shape policy decisions and even the course of history.

Beneath all of the complex and formidable mathematical structures that formulate physical laws rest simple but deep nuggets of truth. It is these simple truths, and not the complicated technical details, that scientists strive for when uncovering the laws of nature. Fortunately, these core ideas can often be illustrated with simple mathematical puzzles. These puzzles are so simplified that one can tackle them and appreciate their meaning without using any complicated math. This book aims to take the reader on a journey to unravel the laws of the universe through fun puzzles. This book includes over a hundred puzzles and their solutions, along with discussion about how they relate to deep ideas in physics and math. Examples are drawn from classical physics, such as Newton's laws and Einstein's theory of relativity, as well as from modern physics, including black holes and string theory. This book is designed for the general public, and it does not require extensive background in mathematics or physics--just a sense of curiosity! About the Author: Cumrun Vafa is the Hollis Professor of Mathematicks and Natural Philosophy in the Physics Department at Harvard University, where he has been teaching and researching theoretical physics since 1985. Professor Vafa is world-renowned for his groundbreaking work in string theory. He is one of the founders of the duality revolution in string theory, which has reshaped our understanding of the fundamental laws of the universe. Professor Vafa has received numerous prizes and recognitions for his work on theoretical physics, including the 2017 Breakthrough Prize in Fundamental Physics and the 2008 Dirac Medal from the ICTP.

The universe has many secrets. It may hide additional dimensions of space other than the familier three we recognize. There might even be another universe adjacent to ours, invisible and unattainable . . . for now. Warped Passages is a brilliantly readable and altogether exhilarating journey that tracks the arc of discovery from early twentieth-century physics to the razor's edge of modern scientific theory. One of the world's leading theoretical physicists, Lisa Randall provides astonishing scientific possibilities that, until recently, were restricted to the realm of science fiction. Unraveling the twisted threads of the most current debates on relativity, quantum mechanics, and gravity, she explores some of the most fundamental questions posed by Nature—taking us into the warped, hidden dimensions underpinning the universe we live in, demystifying the science of the myriad worlds that may exist just beyond our own.

Humanity's ongoing quest to unlock the secrets of dark matter and dark energy Heart of Darkness describes the incredible saga of humankind's quest to unravel the deepest secrets of the universe. Over the past forty years, scientists have learned that two little-understood components—dark matter and dark energy—comprise most of the known cosmos, explain the growth of all cosmic structure, and hold the key to the universe's fate. The story of how evidence for the so-called "Lambda-Cold Dark Matter" model of cosmology has been gathered by generations of scientists throughout the world is told here by one of the pioneers of the field, Jeremiah Ostriker, and his coauthor Simon Mitton. From humankind's early attempts to comprehend Earth's place in the solar system, to astronomers' exploration of the Milky Way galaxy and the realm of the nebulae beyond, to the detection of the primordial fluctuations of energy from which all subsequent structure developed, this book explains the physics and the history of how the current model of our universe arose and has passed every test hurled at it by the skeptics. Throughout this rich story, an essential theme is emphasized: how three aspects of rational inquiry—the application of direct measurement and observation, the introduction of mathematical modeling, and the requirement that hypotheses should be testable and verifiable—guide scientific progress and underpin our modern cosmological paradigm. This monumental puzzle is far from complete, however, as scientists confront the mysteries of the ultimate causes of cosmic structure formation and the real nature and origin of dark matter and dark energy.

As the crowd stood and applauded for the neurophysiologist Du Bois-Reymond’s lecture on August 14, 1872, they did not know that his lecture on the seven riddles of the universe would be long remembered. Scientists at the time believed that science could unlock all of the mysteries of the universe. However, the scientific revolution of the early 20th century fueled by relativity and quantum mechanics would upend the scientific world confirming Du Bois-Reymond’s insights. This book explores the brilliance of Du Bois-Reymond’s life and work and a vastly expanded scientific understanding of these riddles through the modern disciplines of physics, chemistry, and biology. Despite the progress, underlying metaphysical notions still haunt the riddles. Utilizing notions from Whitehead’s Process Philosophy, the author delves into the underlying structure of our universe and outlines the nature of the deity that emerges. Part two of this book examines the riddles consequent demands on theology and religion through the lens of the extraordinary teacher, philosopher, and theologian William DeWitt Hyde. The author clarifies notions about miracles, immortality, and wisdom. This book takes the reader on a vivid, imaginative journey towards unraveling the mysteries of our existence, roles in society, and personal loyalties.

Cooking Cosmos is an exciting book that traces the history of men's endeavor to understand the Universe, and answers the eternal questions: "Who made this World?" "Where did it come from?" "How and why did it begin?" Thousands of years of continual interaction with nature has brought mankind to the present stage when we have some inkling about the working of nature. We now know that the Earth, our habitat, is only one of the planets orbiting the Sun. The Sun itself is a star among billions of stars in the Universe. We know that our solar system came into existence some 4.5 billion years ago and it is but only a tiny component of our galaxy, the Milky Way. Our Universe contains some 100 billion of galaxies. We know that the Universe itself came into existence with the Big Bang some 13.7 billion years ago and even now galaxies are receding from each other with ever increasing speed. This book takes you through the intellectual journey of mankind, unraveling the mysteries of the Cosmos. Starting from Aristotle's Earth-centered Universe, it will take you step by step to the Copernican Sun-centered Universe, to Hubble's expanding Universe, to the Big Bang, to the currently accepted accelerating Universe. In the process, the book explores the origin of space-time, black hole, black hole radiation, dark matter, dark energy, quantum gravity, string theory, all in terms comprehensible to general audiences.
