Book Description
Ten essays on nature, ritual, and philosophy “that are so point-blank vital you nearly need to put the book down to settle yourself” (San Francisco Chronicle). Gretel Ehrlich’s world is one of solitude and wonder, pain and beauty, and these elements give life to her stunning prose. Ever since her acclaimed debut, The Solace of Open Spaces, she has illuminated the particular qualities of nature and the self with graceful precision. In Islands, the Universe, Home, Ehrlich expands her explorations, traveling to the remote reaches of the earth and deep into her soul. She tells of a voyage of discovery in northern Japan, where she finds her “bridge to heaven.” She captures a “light moving down a mountain slope.” She sees a ruined city in the face of a fire-scarred mountain. Above all, she recalls what a painter once told her about art when she was twelve years old, as she sat for her portrait: “You have to mix death into everything. Then you have to mix life into that.” In this unforgettable collection, Ehrlich mixes life and death, real and sacred, to offer a stunning vision of our world that is both achingly familiar and miraculously strange. According to National Book Award–winning author Andrea Barrett, these essays are “as spare and beautiful as the landscape from which they’ve grown. . . . Each one is a pilgrimage into the secrets of the heart.”

Book Description
This volume provides a detailed description of some of the most active areas in astrophysics from the largest scales probed by the Planck satellite to massive black holes that lie at the heart of galaxies and up to the much awaited but stunning discovery of thousands of exoplanets. It contains the following chapters: • Jean-Philippe UZAN, The Big-Bang Theory: Construction, Evolution and Status • Jean-Loup PUGET, The Planck Mission and the Cosmic Microwave Background • Reinhard GENZEL, Massive Black Holes: Evidence, Demographics and Cosmic Evolution • Arnaud CASSAN, New Worlds Ahead: The Discovery of Exoplanets Reinhard Genzel and Andrea Ghez shared the 2020 Nobel Prize in Physics “for the discovery of a supermassive compact object at the centre of our galaxy’”, alongside Roger Penrose “for the discovery that black hole formation is a robust prediction of the general theory of relativity”. The book corresponds to the twentieth Poincaré Seminar, held on November 21, 2015, at Institut Henri Poincaré in Paris. Originally written as lectures to a broad scientific audience, these four chapters are of high value and will be of general interest to astrophysicists, physicists, mathematicians and historians.

Book Description
The award-winning former editor of Science News shows that one of the most fascinating and controversial ideas in contemporary cosmology—the existence of multiple parallel universes—has a long and divisive history that continues to this day. We often consider the universe to encompass everything that exists, but some scientists have come to believe that the vast, expanding universe we inhabit may be just one of many. The totality of those parallel universes, still for some the stuff of science fiction, has come to be known as the multiverse. The concept of the multiverse, exotic as it may be, isn’t actually new. In The Number of the Heavens, veteran science journalist Tom Siegfried traces the history of this controversial idea from antiquity to the present. Ancient Greek philosophers first raised the possibility of multiple universes, but Aristotle insisted on one and only one cosmos. Then in 1277 the bishop of Paris declared it heresy to teach that God could not create as many universes as he pleased, unleashing fervent philosophical debate about whether there might exist a “plurality of worlds.” As the Middle Ages gave way to the Renaissance, the philosophical debates became more scientific. René Descartes declared “the number of the heavens” to be indefinitely large, and as notions of the known universe expanded from our solar system to our galaxy, the debate about its multiplicity was repeatedly recast. In the 1980s, new theories about the big bang reignited interest in the multiverse. Today the controversy continues, as cosmologists and physicists explore the possibility of many big bangs, extra dimensions of space, and a set of branching, parallel universes. This engrossing story offers deep lessons about the nature of science and the quest to understand the universe.

Book Description
No modern astronomer made a more profound contribution to our understanding of the cosmos than did Edwin Hubble, who first conclusively demonstrated that the universe is expanding. Basing his theory on the observation of the change in distanct galaxies, called red shift, Hubble showed that this is a Doppler effect, or alteration in the wavelength of light, resulting from the rapid motion of celestial objects away from Earth. In 1935, Hubble described his principal observations and conclusions in the Silliman lectures at Yale University. These lectures were published the following year as "The Realm of the Nebulae," which quickly became a classic work.

Book Description
Popular culture constantly bombards us with the idea that modern scientific knowledge has rendered Christianity obsolete. The common conception is that those who believe in God do so through blind faitha faith that is devoid of proof and in contrast with scientific knowledge. However despite this perception, there are multiple independent scholarly arguments that point toward the existence of a Christian God, including: the weakness of naturalism as an explanation for our world; the congruency of God and modern science, including evolution; the cosmological argument and the beginning of the universe; the intelligent design of our universe; the existence of an objective moral law; the secular sources that confirm the life and events of Jesus Christ; the credibility of the New Testament; and the historical evidence for the death and resurrection of Jesus Christ. While belief in God is not an academic conclusion, God did not leave us without any indications of his existence. These independent arguments build a cumulative case that leads to the logical conclusion that God really does exist, and therefore, Faith Isnt Blind.

Book Description
Today, we recognize that we live on a planet circling the sun, that our sun is just one of billions of stars in the galaxy we call the Milky Way, and that our galaxy is but one of billions born out of the Big Bang. Yet as recently as the early twentieth century, the general public and even astronomers had vague and confused notions about what lay beyond the visible stars. Can we see to the edge of the universe? Do we live in a system that would look, from a distance, like a spiral nebula? This fully updated second edition of Minding the Heavens: The Story of Our Discovery of the Milky Way explores how we learned that we live in a galaxy, in a universe of composed of galaxies and unseen, mysterious dark matter. The story unfolds through short biographies of seven astronomers: Thomas Wright, William Herschel, and Wilhelm Struve of the 18th and 19th centuries; the transitional figure of William Huggins; and Jacobus Kapteyn, Harlow Shapley, and Edwin Hubble of the modern, big-telescope era. Each contributed key insights to our present understanding of where we live in the cosmos, and each was directly inspired by the work of his predecessors to decipher "the construction of the heavens." Along the way the narrative weaves in the contributions of those in supportive roles, including Caroline Herschel—William’s sister, and the first woman paid to do astronomy—and Martha Shapley, a mathematician in her own right who carried out calculations for her spouse. Through this historical perspective readers will gain a new appreciation of our magnificent Milky Way galaxy and of the beauties of the night sky, from ghostly nebulae to sparkling star clusters. Features: Fully updated throughout to reflect the latest in our understanding of the Milky Way, from our central supermassive black hole to the prospect of future mergers with other galaxies in our Local Group. Explains the significance of current research, including from the Gaia mission mapping our galaxy in unprecedented detail Unique and broadly appealing approach. A biographical framework and ample illustrations lead the reader by easy, enjoyable steps to a well-rounded understanding of the history of astronomy. Praise for the first edition— "A terrific blend of the science and the history." - Marth Haynes, Goldwin Smith Professor of Astronomy, Cornell University "The book is a treat... Highly recommended for public and academic libraries." -Peter Hepburn (now Head Librarian, College of the Canyons, Santa Clarita, California)
