Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.

    Alvarez had the first glimmer of that amazing insight when he noticed something odd in a rock outcrop in central Italy. Alvarez now returns to that rich terrain, this time to take the reader on an excavation of the Earth's distant past. We encounter the volcanoes that formed the Seven Hills of Rome; the majestic limestone Apennine mountains that started to develop millions of years ago under water; the evidence that the Mediterranean Sea completely evaporated to a sunken desert, perhaps several times; and the proof that continental plates once overran one another to form the Alps. In Alvarez's telling, all major geologic episodes are as dramatic as the great impact that killed the dinosaurs, even when they happen over eons and without huge creatures to witness them.

    After the Ice is the story of this momentous period--one in which a seemingly minor alteration in temperature could presage anything from the spread of lush woodland to the coming of apocalyptic floods--and one in which we find the origins of civilization itself.Drawing on the latest research in archaeology, human genetics, and environmental science, After the Ice takes the reader on a sweeping tour of 15,000 years of human history. Steven Mithen brings this world to life through the eyes of an imaginary modern traveler--John Lubbock, namesake of the great Victorian polymath and author of Prehistoric Times. With Lubbock, readers visit and observe communities and landscapes, experiencing prehistoric life--from aboriginal hunting parties in Tasmania, to the corralling of wild sheep in the central Sahara, to the efforts of the Guila Naquitz people in Oaxaca to combat drought with agricultural innovations.Part history, part science, part time travel, After the Ice offers an evocative and uniquely compelling portrayal of diverse cultures, lives, and landscapes that laid the foundations of the modern world.

    Richard Leakey's personal account of his fossil hunting and landmark discoveries at Lake Turkana, his reassessment of human prehistory based on new evidence and analytic techniques, and his profound pondering of how we became "human" and what being "human" really means.

    Now, in The New Science of the Human Past, Reich describes just how the human genome provides not only all the information that a fertilized human egg needs to develop but also contains within it the history of our species. He delineates how the Genomic Revolution and ancient DNA are transforming our understanding of our own lineage as modern humans; how genomics deconstructs the idea that there are no biologically meaningful differences among human populations (though without adherence to pernicious racist hierarchies); and how DNA studies reveal the deep history of human inequality--among different populations, between the sexes, and among individuals within a population.

    It was the battle that countless armies tried to imitate, most notably in World Wars I & II, the battle that obsessed military minds. Yet no general ever matched Hannibal's unexpected, innovative & brutal military victory--the costliest day of combat for any army in history. Robert L. O'Connell, an admired military historian, now tells the whole story of Cannae, giving a stirring account of this apocalyptic battle of the 2nd Punic War, its causes & consequences. O'Connell shows how a restive Rome amassed a giant army to punish Carthage's commander, who'd dealt them deadly blows at Trebia & Lake Trasimene, & how Hannibal outwitted enemies that outnumbered him. He describes Hannibal's strategy of blinding his opponents with sun & dust, enveloping them in a deadly embrace & sealing their escape, before launching a massive knife fight that would kill 48,000 men in close contact. The Ghosts of Cannae then conveys how this disastrous pivot point in Rome's history ultimately led to the republic's resurgence & the creation of its empire. Piecing together decayed shreds of ancient reportage, the author paints powerful portraits of the leading players: Hannibal, resolutely sane & uncannily strategic; Varro, Rome's co-consul scapegoated for the loss; & Scipio Africanus, the surviving, self-promoting Roman military tribune who would one day pay back Hannibal at Zama in N. Africa. Finally, O'Connell reveals how Cannae's legend has inspired & haunted military leaders ever since, & the lessons it teaches. Superbly researched, written with erudite wit, The Ghosts of Cannae is the definitive account of a battle whose history still resonates.

    The Oracle of Delphi was one of the most influential figures in ancient Greece. Human mistress of the god Apollo, she had the power to enter into ecstatic communion with him and deliver his prophesies to men. Thousands of years later, Pulitzer Prize–winning journalist William J. Broad follows a crew of enterprising researchers as they sift through the evidence of history, geology, and archaeology to reveal—as far as science is able—the source of her visions.

    Not all the passages have survived, but in those that have the depth and diversity of genius are manifest. From a vicious, vituperative biography of Tiberius to the more straightforward accounts of Gaius (Caligula), Claudius and Nero, which reveal an extraordinary gift for pictorial description, the Annals carry conviction both as a work of art and as a history. Michael Grant's tranlation of The Annals is a fine one. It captures the emotional patriotism of Tacitus's moral tone, offset by a lucid understanding that Rome is doomed, and conveys with vigor the lives of the great emperors who laid the foundations of modern Europe.

    To give a new voice to the new nation shaken by civil war, he spent his entire life revising and adding to the work, but his initial act of bravado in answering Ralph Waldo Emerson's call for a national poet has made Whitman the quintessential American writer. This rich cross-section of his work includes poems from throughout Whitman's lifetime as published on his deathbed edition of 1891 and other works.

    More than forty years after its first publication this masterful survey remains the standard textbook on the central period of Roman history.

    Colin Wells's vivid account is now available in an up-to-date second edition.

    Using 100s of fascinating examples, James Burke shows how old established ideas in science and technology often lead to serendipitous and amazing modern discoveries and innovations.

    Our sense of its age was vague and vastly off the mark, and much of the knowledge of our own species’ history was a set of fantastic myths and fairy tales. In the tradition of The Microbe Hunters and Gods, Graves, and Scholars, Sean Carroll leads a rousing voyage that recounts the most important discoveries in two centuries of natural history: from Darwin’s trip around the world to Charles Walcott’s discovery of pre-Cambrian life in the Grand Canyon; from Louis and Mary Leakey’s investigation of our deepest past in East Africa to the trailblazers in modern laboratories who have located a time clock in our DNA.

    Volume 1 was published in 1776, going thru six printings; 2-3 in 1781; 4-6 in 1788-89. It was a major literary achievement of the 18th century, adopted as a model for the methodologies of historians.The books cover the Roman Empire after Marcus Aurelius, from 180 to 1590. They take as their material the behavior & decisions that led to the eventual fall of the Empire in East & West, offering explanations.Gibbon is called the 1st modern historian of ancient Rome. By virtue of its mostly objective approach & accurate use of reference material, his work was adopted as a model for the methodologies of 19-20th century historians. His pessimism & detached irony was common to the historical genre of his era. Although he published other books, Gibbon devoted much of his life (1772-89) to this one work. His Memoirs of My Life & Writings is devoted largely to his reflections on how the book virtually became his life. He compared the publication of each succeeding volume to a newborn.Gibbon offers an explanation for why the Roman Empire fell, a task difficult because of few comprehensive written sources, tho he wasn't the only historian to tackle the subject. Most of his ideas are taken from what few relevant records were available: those of Roman moralists of the 4-5th centuries. According to Gibbon, the Empire succumbed to barbarian invasions because of lost of civic virtue. They'd become weak, outsourcing defence to barbarian mercenaries, who became so numerous & ingrained that they took over. Romans had become effeminate, incapable of tough military lifestyles. In addition, Christianity created belief that a better life existed after death, fostering indifference to the present, sapping patriotism. Its comparative pacifism tended to hamper martial spirit. Lastly, like other Enlightenment thinkers, he held in contempt the Middle Ages as a priest-ridden, superstitious, dark age. It wasn't until his age of reason that history could progress.

    For centuries, the power of zero savored of the demonic; once harnessed, it became the most important tool in mathematics. Zero follows this number from its birth as an Eastern philosophical concept to its struggle for acceptance in Europe and its apotheosis as the mystery of the black hole. Today, zero lies at the heart of one of the biggest scientific controversies of all time, the quest for the theory of everything. Elegant, witty, and enlightening, Zero is a compelling look at the strangest number in the universe and one of the greatest paradoxes of human thought.
