Available in PDF, EPUB and Kindle. Book excerpt: Bored during Mass at the cathedral in Pisa, the seventeen-year-old Galileo regarded the chandelier swinging overhead--and remarked, to his great surprise, that the lamp took as many beats to complete an arc when hardly moving as when it was swinging widely. Galileo's Pendulum tells the story of what this observation meant, and of its profound consequences for science and technology. The principle of the pendulum's swing--a property called isochronism--marks a simple yet fundamental system in nature, one that ties the rhythm of time to the very existence of matter in the universe. Roger Newton sets the stage for Galileo's discovery with a look at biorhythms in living organisms and at early calendars and clocks--contrivances of nature and culture that, however adequate in their time, did not meet the precise requirements of seventeenth-century science and navigation. Galileo's Pendulum recounts the history of the newly evolving time pieces--from marine chronometers to atomic clocks--based on the pendulum as well as other mechanisms employing the same physical principles, and explains the Newtonian science underlying their function. The book ranges nimbly from the sciences of sound and light to the astonishing intersection of the pendulum's oscillations and quantum theory, resulting in new insight into the make-up of the material universe. Covering topics from the invention of time zones to Isaac Newton's equations of motion, from Pythagoras' theory of musical harmony to Michael Faraday's field theory and the development of quantum electrodynamics, Galileo's Pendulum is an authoritative and engaging tour through time of the most basic all-pervading system in the world.

Download or read book The Number of the Heavens written by Tom Siegfried and published by Harvard University Press. This book was released on 2019-09-17 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: This book is significant for its concept of "openness"--the artist's decision to leave arrangements of some constituents of a work to the public or to chance--and for its anticipation of two themes of literary theory: the element of multiplicity and plurality in art, and the insistence on literary response as an interaction between reader and text.

Book excerpt: For fans of Lovecraft Country and Candyman comes a witchy story full of Black girl magic! One girl′s dark ability to summon the dead offers her a chance at a new life, while revealing to her an even darker future. “Practical Magic meets Black Girl Magic in this powerful addition to the YA canon. I couldn′t put it down.” —#1 New York Times Bestselling Author Victoria Schwab Katrell can talk to the dead. And she wishes it made more money. She’s been able to support her unemployed mother—and Mom’s deadbeat-boyfriend-of-the-week—so far, but it isn’t enough. Money’s still tight, and to complicate things, Katrell has started to draw attention. Not from this world—from beyond. And it comes with a warning: STOP, or there will be consequences. Katrell is willing to call the ghosts on their bluff; she has no choice. What do ghosts know of having sleep for dinner? But when her next summoning accidentally raises someone from the dead, Katrell realizes that a live body is worth a lot more than a dead apparition. And, warning or not, she has no intention of letting this lucrative new business go. Only, magic isn’t free, and dark forces are coming to collect. Now Katrell faces a choice: resign herself to poverty, or confront the darkness before it’s too late.

Download or read book Homo Migrans written by Megan J. Daniels and published by State University of New York Press. This book was released on 2022-04-01 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most significant challenges in archaeology is understanding how (and why) humans migrate. Homo Migrans examines the past, present, and future states of migration and mobility studies in archaeological discourse. Contributors draw on revolutionary twenty-first-century advances in genetics, isotope studies, and data manipulation that have resolved longstanding debates about past human movement and have helped clarify the relationships between archaeological remains and human behavior and identity. These emerging techniques have also pressed archaeologists and historians to develop models that responsibly incorporate method, theory, and data in ways that honor the complexity of human behavior and relationships. This volume articulates the challenges that lie ahead as scholars draw from genomic studies, computational science, social theory, cognitive and evolutionary studies, environmental history, and network analysis to clarify the nature of human migration in world history. With case studies focusing on European and Mediterranean history and prehistory (as well as global history), Homo Migrans presents integrated methodologies and analyses that will interest any scholar researching migration and mobility in the human past.

Book excerpt: From the bestselling author of The Frozen River comes an enthralling historical mystery that unravels the extraordinary twists and turns in Anna Anderson’s fifty-year battle to be recognised as Anastasia Romanov. Is she the Russian grand duchess or the thief of another woman’s legacy? Countless others have rendered their verdict. Now it is your turn. Russia, 1918: Under direct orders from Vladimir Lenin, Bolshevik secret police herd Anastasia Romanov, along with the entire imperial family, into a damp basement in Siberia, where they face a merciless firing squad. None survive. At least that is what the executioners have always claimed. Germany, 1920: A young woman bearing an uncanny resemblance to Anastasia Romanov is pulled shivering and senseless from a canal. Refusing to explain her presence in the freezing water or even acknowledge her rescuers, Anna Anderson is taken to the hospital where an examination reveals that her body is riddled with countless horrific scars. When she finally does speak, this frightened, mysterious young woman claims to be the Russian grand duchess. As rumours begin to circulate that the youngest Romanov daughter survived the massacre, old enemies and new threats awaken. I Was Anastasia unravels the thrilling mystery around Anna Anderson in a tale that is every bit as moving and momentous as it is harrowing and twisted.

Available in PDF, EPUB and Kindle. Book excerpt: "Edgar Allan Poe is one of American culture's most iconic figures, inspiring countless derivations beyond the literary realm, from commercial illustration and kitch to art installations and video games. Why has Poe been so hugely influential in media other than his own? What do filmmakers, composers, and other artists find in Poe that suits their purposes so often and so variously? Poe's works are violent and brooding, memorable both for certain grisly images and for certain prevailing moods-dread, creepiness, mournfulness. They are, in other words, distinctly graphic and richly atmospheric. Jonathan Elmer locates the source of Poe's fascination for artists in these two vernacular aesthetic categories-the graphic and the atmospheric-and how well they describe our experience of the multi-media world. Elmer uses Poe to explore these two terms and track some deep patterns in their use, not through theoretical labor but through close encounters with a wide sampling of aesthetic objects that avail themselves of Poe's work. Poe, we learn, has come to exemplify a modern method of aesthetic production. It is as if he left his box of tools lying around for others to pick up and play with. The bundle of Poe traits-his thematic emphasis on extreme sensation, his flexible sense of form, his experimental and modular method, his iconic personal profile-amount to what could be called a Poe "brand," one as likely to be found in music videos or comics as in novels and stories. Ranging from René Magritte and Claude Debussy to Lou Reed, Roger Corman, and Spongebob Squarepants, Elmer shows how the Poe brand opens trunk lines to aesthetic experiences fundamental to a multi-media world"--

Download or read book Sitting Pretty written by Rebekah Taussig and published by HarperCollins. This book was released on 2020-08-25 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: A memoir-in-essays from disability advocate and creator of the Instagram account @sitting_pretty Rebekah Taussig, processing a lifetime of memories to paint a beautiful, nuanced portrait of a body that looks and moves differently than most. Growing up as a paralyzed girl during the 90s and early 2000s, Rebekah Taussig only saw disability depicted as something monstrous (The Hunchback of Notre Dame), inspirational (Helen Keller), or angelic (Forrest Gump). None of this felt right; and as she got older, she longed for more stories that allowed disability to be complex and ordinary, uncomfortable and fine, painful and fulfilling. Writing about the rhythms and textures of what it means to live in a body that doesn’t fit, Rebekah reflects on everything from the complications of kindness and charity, living both independently and dependently, experiencing intimacy, and how the pervasiveness of ableism in our everyday media directly translates to everyday life. Disability affects all of us, directly or indirectly, at one point or another. By exploring this truth in poignant and lyrical essays, Taussig illustrates the need for more stories and more voices to understand the diversity of humanity. Sitting Pretty challenges us as a society to be patient and vigilant, practical and imaginative, kind and relentless, as we set to work to write an entirely different story.
