In the past few years, a handful of scientists have been in a race to explain a disturbing aspect of our universe: only 4 percent of it consists of the matter that makes up you, me, our books, and every planet, star, and galaxy. The rest—96 percent of the universe—is completely unknown.   Richard Panek tells the dramatic story of how scientists reached this conclusion, and what they’re doing to find this "dark" matter and an even more bizarre substance called dark energy. Based on in-depth, on-site reporting and hundreds of interviews—with everyone from Berkeley’s feisty Saul Perlmutter and Johns Hopkins’s meticulous Adam Riess to the quietly revolutionary Vera Rubin—the book offers an intimate portrait of the bitter rivalries and fruitful collaborations, the eureka moments and blind alleys, that have fueled their search, redefined science, and reinvented the universe.

    And since medieval Europe was the cradle of modern Western society, this work is vital for understanding our world and how it came into being.

    Although written over four hundred years after Alexander’s death, Arrian’s Campaigns of Alexander is the most reliable account of the man and his achievements we have. Arrian’s own experience as a military commander gave him unique insights into the life of the world’s greatest conqueror. He tells of Alexander’s violent suppression of the Theban rebellion, his total defeat of Persia, and his campaigns through Egypt, India and Babylon – establishing new cities and destroying others in his path. While Alexander emerges from this record as an unparalleled and charismatic leader, Arrian succeeds brilliantly in creating an objective and fully rounded portrait of a man of boundless ambition, who was exposed to the temptations of power and worshipped as a god in his own lifetime.Aubrey de Sélincourt’s vivid translation is accompanied by J. R. Hamilton’s introduction, which discusses Arrian’s life and times, his synthesis of other classical sources and the composition of Alexander’s army. The edition also includes maps, a list for further reading and a detailed index.For more than seventy years, Penguin has been the leading publisher of classic literature in the English-speaking world.

    Why do living things and physical phenomena take the forms they do? Analyzing the mathematical and physical aspects of biological processes, this historic work, first published in 1917, has become renowned as well for the poetry of is descriptions.

    Embodying a ritual to be performed for the dead, with detailed instructions for the behavior of the disembodied spirit in the Land of the Gods, it served as the most important repository of religious authority for some three thousand years. Chapters were carved on the pyramids of the ancient 5th Dynasty, texts were written in papyrus, and selections were painted on mummy cases well into the Christian Era. In a certain sense it stood behind all Egyptian civilization.In the year 1888 Dr. E. Wallis Budge, then purchasing agent for the British Museum, followed rumors he heard of a spectacular archaeological find in Upper Egypt, and found in an 18th Dynasty tomb near Luxor "the largest roll of papyrus I had ever seen, tied with a thick band of papyrus, and in a perfect state of preservation." It was a copy of the Egyptian Book of the Dead, written around 1500 B.C. for Ani, Royal Scribe of Thebes, Overseer of the Granaries of the Lords of Abydos, and Scribe of the Offerings of the Lords of Thebes.The Papyrus of Ani, a full version of the Theban recension, is presented here by Dr. Budge, who later became perhaps the world's most renowned Egyptologist. Reproduced in full are a clear copy of the Egyptian hieroglyphs, and interlinear transliteration of their sounds (as reconstructed), a word-for-word translation, and separately a complete smooth translation. All this is preceded by an introduction of more than 150 pages. As a result of this multiple apparatus the reader has a unique opportunity to savor all aspects of the Book of the Dead, or as it is otherwise known, the Book of the Great Awakening.

    Under the editorship of Herbert Golder and the late William Arrowsmith, each volume includes a critical introduction, commentary on the text, full stage directions, and a glossary of the mythical and geographical references in the plays. Produced more frequently on the ancient stage than any other tragedy, Orestes retells with striking innovations the story of the young man who kills his mother to avenge her murder of his father. Though eventually exonerated, Orestes becomes a fugitive from the Furies (avenging spirits) of his mother's blood. On the brink of destruction, he is saved in the end by Apollo, who had commanded the matricide. Powerful and gripping, Orestes sweeps us along with a momentum that starting slowly, builds inevitably to one of the most spectacular climaxes in all Greek tragedy.

    Over the next two decades, Copernicus expanded his theory through hundreds of observations, while compiling in secret a book-length manuscript that tantalized mathematicians and scientists throughout Europe. For fear of ridicule, he refused to publish.In 1539, a young German mathematician, Georg Joachim Rheticus, drawn by rumors of a revolution to rival the religious upheaval of Martin Luther's Reformation, traveled to Poland to seek out Copernicus. Two years later, the Protestant youth took leave of his aging Catholic mentor and arranged to have Copernicus's manuscript published, in 1543, as De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres)-the book that forever changed humankind's place in the universe.In her elegant, compelling style, Dava Sobel chronicles, as nobody has, the conflicting personalities and extraordinary discoveries that shaped the Copernican Revolution. At the heart of the book is her play And the Sun Stood Still, imagining Rheticus's struggle to convince Copernicus to let his manuscript see the light of day. As she achieved with her bestsellers Longitude and Galileo's Daughter, Sobel expands the bounds of narration, giving us an unforgettable portrait of scientific achievement, and of the ever-present tensions between science and faith.

    A eulogy to Italy as the temperate land of perpetual spring, and a celebration of the values of rustic piety, The Georgics is probably the supreme achievement of Latin poetry.

    Astrophysicist Adam Frank traces the question of alien life and intelligence from the ancient Greeks to the leading thinkers of our own time, and shows how we as a civilization can only hope to survive climate change if we recognize what science has recently discovered: that we are just one of ten billion trillion planets in the Universe, and it’s highly likely that many of those planets hosted technologically advanced alien civilizations. What’s more, each of those civilizations must have faced the same challenge of civilization-driven climate change.Written with great clarity and conviction, Light of the Stars builds on the inspiring work of pioneering scientists such as Frank Drake and Carl Sagan, whose work at the dawn of the space age began building the new science of astrobiology; Jack James, the Texas-born engineer who drove NASA’s first planetary missions to success; Vladimir Vernadsky, the Russian geochemist who first envisioned the Earth’s biosphere; and James Lovelock and Lynn Margulis, who invented Gaia theory. Frank recounts the perilous journey NASA undertook across millions of miles of deep space to get its probes to Venus and Mars, yielding our first view of the cosmic laws of planets and climate that changed our understanding of our place in the universe.Thrilling science at the grandest of scales, Light of the Stars explores what may be the largest question of all: What can the likely presence of life on other worlds tell us about our own fate?

    As a philosophy, however, it also denoted the striving after an independent state of mind and body, imperturbability, and reliance on sensory data as the true basis of knowledge.Epicurus (ca. 341-271 B.C.) founded one of the most famous and influential philosophical schools of antiquity. In these remains of his vast output of scientific and ethical writings, we can trace Epicurus' views on atomism, physical sensation, duty, morality, the soul, and the nature of the gods.

    St. Thomas Aquinas has much to teach us--most especially how to confront the classic questions that are still with us after centuries of thought.

    Odysseus' reliance on his wit and wiliness for survival in his encounters with divine and natural forces, during his ten-year voyage home to Ithaca after the Trojan War, is at once a timeless human story and an individual test of moral endurance. In the myths and legends that are retold here, Fagles has captured the energy and poetry of Homer's original in a bold, contemporary idiom, and given us an Odyssey to read aloud, to savor, and to treasure for its sheer lyrical mastery.Renowned classicist Bernard Knox's superb Introduction and textual commentary provide new insights and background information for the general reader and scholar alike, intensifying the strength of Fagles' translation.This is an Odyssey to delight both the classicist and the public at large, and to captivate a new generation of Homer's students.--Robert Fagles, winner of the PEN/Ralph Manheim Medal for Translation and a 1996 Academy Award in Literature from the American Academy of Arts and Letters, presents us with Homer's best-loved and most accessible poem in a stunning new modern-verse translation.

    From Edward Lorenz’s discovery of the Butterfly Effect, to Mitchell Feigenbaum’s calculation of a universal constant, to Benoit Mandelbrot’s concept of fractals, which created a new geometry of nature, Gleick’s engaging narrative focuses on the key figures whose genius converged to chart an innovative direction for science. In Chaos, Gleick makes the story of chaos theory not only fascinating but also accessible to beginners, and opens our eyes to a surprising new view of the universe.

    For the events between 133 and 70 BC he is the only surviving continuous narrative source. The subsequent books vividly describe Catiline's conspiracy, the rise and fall of the First Triumvirate, and Caesar's crossing of the Rubicon, defeat of Pompey and untimely death. The climax comes with the birth of the Second Triumvirate out of anarchy, the terrible purges of Proscriptions which followed, and the titanic struggle for world mastery which was only to end with Augustus's defeat of Antony and Cleopatra. If Appian's Roman History as a whole reveals how an empire was born of the struggle against a series of external enemies, these five books concentrate on an even greater ordeal. Despite the rhetorical flourishes, John Carter suggests in his Introduction, the impressive 'overall conception of the decline of the Roman state into violence, with its sombre highlights and the leitmotif of fate, is neither trivial nor inaccurate'.
