In this fascinating book, Mario Livio tells the tale of a number at the heart of that mystery: phi, or 1.6180339887...This curious mathematical relationship, widely known as "The Golden Ratio," was discovered by Euclid more than two thousand years ago because of its crucial role in the construction of the pentagram, to which magical properties had been attributed. Since then it has shown a propensity to appear in the most astonishing variety of places, from mollusk shells, sunflower florets, and rose petals to the shape of the galaxy. Psychological studies have investigated whether the Golden Ratio is the most aesthetically pleasing proportion extant, and it has been asserted that the creators of the Pyramids and the Parthenon employed it. It is believed to feature in works of art from Leonardo da Vinci's Mona Lisa to Salvador Dali's The Sacrament of the Last Supper, and poets and composers have used it in their works. It has even been found to be connected to the behavior of the stock market!The Golden Ratio is a captivating journey through art and architecture, botany and biology, physics and mathematics. It tells the human story of numerous phi-fixated individuals, including the followers of Pythagoras who believed that this proportion revealed the hand of God; astronomer Johannes Kepler, who saw phi as the greatest treasure of geometry; such Renaissance thinkers as mathematician Leonardo Fibonacci of Pisa; and such masters of the modern world as Goethe, Cezanne, Bartok, and physicist Roger Penrose. Wherever his quest for the meaning of phi takes him, Mario Livio reveals the world as a place where order, beauty, and eternal mystery will always coexist.From the Hardcover edition.

    It can also mean the humbler tools of everyday cooking and eating: a wooden spoon and a skillet, chopsticks and forks.Since prehistory, humans have braved sharp knives, fire, and grindstones to transform raw ingredients into something delicious - or at least edible. Tools shape what we eat, but they have also transformed how we consume, and how we think about, our food. Technology in the kitchen does not just mean the Pacojets and sous-vide of the modernist kitchen. It can also mean the humbler tools of everyday cooking and eating: a wooden spoon and a skillet, chopsticks and forks. In Consider the Fork, award-winning food writer Bee Wilson provides a wonderful and witty tour of the evolution of cooking around the world, revealing the hidden history of everyday objects we often take for granted. Knives - perhaps our most important gastronomic tool - predate the discovery of fire, whereas the fork endured centuries of ridicule before gaining widespread acceptance; pots and pans have been around for millennia, while plates are a relatively recent invention. Many once-new technologies have become essential elements of any well-stocked kitchen - mortars and pestles, serrated knives, stainless steel pots, refrigerators. Others have proved only passing fancies, or were supplanted by better technologies; one would be hard pressed now to find a water-powered egg whisk, a magnet-operated spit roaster, a cider owl, or a turnspit dog. Although many tools have disappeared from the modern kitchen, they have left us with traditions, tastes, and even physical characteristics that we would never have possessed otherwise. Blending history, science, and anthropology, Wilson reveals how our culinary tools and tricks came to be, and how their influence has shaped modern food culture. The story of how we have tamed fire and ice and wielded whisks, spoons, and graters, all for the sake of putting food in our mouths, Consider the Fork is truly a book to savor.

    Drawing on the black feminist tradition, including Audre Lourde’s invitation to use the erotic as power and Toni Cade Bambara’s exhortation that we make the revolution irresistible, the contributors to this volume take up the challenge to rethink the ground rules of activism. Writers including Cara Page of the Astraea Lesbian Foundation For Justice, Sonya Renee Taylor, founder of This Body Is Not an Apology, and author Alexis Pauline Gumbs cover a wide array of subjects— from sex work to climate change, from race and gender to sex and drugs—creating new narratives about how politics can feel good and how what feels good always has a complex politics of its own.Building on the success of her popular Emergent Strategy, brown launches a new series of the same name with this volume, bringing readers books that explore experimental, expansive, and innovative ways to meet the challenges that face our world today. Books that find the opportunity in every crisis!

    If reason is so useful, why didn't it also evolve in other animals? If reason is that reliable, why do we produce so much thoroughly reasoned nonsense? In their groundbreaking account of the evolution and workings of reason, Hugo Mercier and Dan Sperber set out to solve this double enigma. Reason, they argue with a compelling mix of real-life and experimental evidence, is not geared to solitary use, to arriving at better beliefs and decisions on our own. What reason does, rather, is help us justify our beliefs and actions to others, convince them through argumentation, and evaluate the justifications and arguments that others address to us.In other words, reason helps humans better exploit their uniquely rich social environment. This interactionist interpretation explains why reason may have evolved and how it fits with other cognitive mechanisms. It makes sense of strengths and weaknesses that have long puzzled philosophers and psychologists--why reason is biased in favor of what we already believe, why it may lead to terrible ideas and yet is indispensable to spreading good ones.Ambitious, provocative, and entertaining, The Enigma of Reason will spark debate among psychologists and philosophers, and make many reasonable people rethink their own thinking.

    But how did these once-taboo toys become so socially acceptable? The journey of the devices to the cultural mainstream is a surprisingly stimulating one.In Buzz, Hallie Lieberman—who holds the world’s first PhD in the history of sex toys—starts at the beginning, tracing the tale from lubricant in Ancient Greece to the very first condom in 1560 to advertisements touting devices as medical equipment in 19th-century magazines. She looks in particular from the period of major change from the 1950s through the present, when sex toys evolved from symbols of female emancipation to tools in the fight against HIV/AIDS to consumerist marital aids to today's mainstays of pop culture. The story is populated with a cast of vivid and fascinating characters including Dell Williams, founder of the first feminist sex toy store, Eve’s Garden; Betty Dodson, who pioneered “Bodysex” workshops in the 1960s to help women discover vibrators and ran Good Vibrations, a sex toy store and vibrator museum; and Gosnell Duncan, a paraplegic engineer who invented the silicone dildo and lobbied Dodson and Williams to sell them in their stores. And these personal dramas are all set against a backdrop of changing American attitudes toward sexuality, feminism, LGBTQ issues, and more.Both educational and titillating, Buzz will make readers think quite differently about those secret items hiding in bedside drawers across the nation.

    Cacioppo’s groundbreaking research topples one of the pillars of modern medicine and psychology: the focus on the individual as the unit of inquiry. By employing brain scans, monitoring blood pressure, and analyzing immune function, he demonstrates the overpowering influence of social context—a factor so strong that it can alter DNA replication. He defines an unrecognized syndrome—chronic loneliness—brings it out of the shadow of its cousin depression, and shows how this subjective sense of social isolation uniquely disrupts our perceptions, behavior, and physiology, becoming a trap that not only reinforces isolation but can also lead to early death. He gives the lie to the Hobbesian view of human nature as a “war of all against all,” and he shows how social cooperation is, in fact, humanity’s defining characteristic. Most important, he shows how we can break the trap of isolation for our benefit both as individuals and as a society.

    There have been other books on Dr Morell's cocktail of treatments for Hitler and Goering's reliance on drugs, but Ohler's book is the first to show how the entire Nazi regime was permeated with drugs - cocaine, heroin, morphine and methamphetamines, the last of these crucial to troops' resilience and partly explaining German victory in 1940. Ohler is explicit that drugs cannot explain Third Reich ideology, but their promiscuous use impaired and confused decision-making, with drastic effects on Hitler and his entourage, who, as the war turned against Germany, took refuge in ever more poorly understood cocktails of stimulants. This chemical euphoria changes how we should think about the Nazi high command and its ability to understand the situation it found itself in by 1944-45. As such Blitzed will force a wider reinterpretation of several key events during the Second World War.

    Religion. Race. Nationality. Class. Culture. Such affiliations give contours to our sense of self, and shape our polarized world. Yet the collective identities they spawn are riddled with contradictions, and cratered with falsehoods.Kwame Anthony Appiah’s "The Lies That Bind" is an incandescent exploration of the nature and history of the identities that define us. It challenges our assumptions about how identities work. We all know there are conflicts between identities, but Appiah shows how identities are created by conflict. Religion, he demonstrates, gains power because it isn’t primarily about belief. Our everyday notions of race are the detritus of discarded nineteenth-century science. Our cherished concept of the sovereign nation―of self-rule―is incoherent and unstable. Class systems can become entrenched by efforts to reform them. Even the very idea of Western culture is a shimmering mirage.From Anton Wilhelm Amo, the eighteenth-century African child who miraculously became an eminent European philosopher before retiring back to Africa, to Italo Svevo, the literary marvel who changed citizenship without leaving home, to Appiah’s own father, Joseph, an anticolonial firebrand who was ready to give his life for a nation that did not yet exist, Appiah interweaves keen-edged argument with vibrant narratives to expose the myths behind our collective identities.These “mistaken identities,” Appiah explains, can fuel some of our worst atrocities―from chattel slavery to genocide. And yet, he argues that social identities aren’t something we can simply do away with. They can usher in moral progress and bring significance to our lives by connecting the small scale of our daily existence with larger movements, causes, and concerns.Elaborating a bold and clarifying new theory of identity, "The Lies That Bind" is a ringing philosophical statement for the anxious, conflict-ridden twenty-first century. This book will transform the way we think about who―and what―“we” are.

    Its telling plunges the reader down the dark alleys of 18th-century London's underworld, a realm populated by tavern owners, pimps, punters, card sharps, and of course, a colorful range of prostitutes and brothel-keepers.

    She attends industry conferences, interviews producers and performers, and speaks to hundreds of men and women each year about their experience with porn. Students and educators describe her work as "life changing."In Pornland—the culmination of her life's work—Dines takes an unflinching look at porn and its affect on our lives. Astonishingly, the average age of first viewing porn is now 11.5 years for boys, and with the advent of the Internet, it's no surprise that young people are consuming more porn than ever. But, as Dines shows, today's porn is strikingly different from yesterday's Playboy. As porn culture has become absorbed into pop culture, a new wave of entrepreneurs are creating porn that is even more hard-core, violent, sexist, and racist. To differentiate their products in a glutted market, producers have created profitable niche products—like teen sex, torture porn, and gonzo—in order to entice a generation of desensitized users.Going from the backstreets to Wall Street, Dines traces the extensive money trail behind this multibillion-dollar industry—one that reaps more profits than the film and music industries combined. Like Big Tobacco—with its powerful lobbying groups and sophisticated business practices—porn companies don't simply sell products. Rather they influence legislators, partner with mainstream media, and develop new technologies like streaming video for cell phones. Proving that this assembly line of content is actually limiting our sexual freedom, Dines argues that porn's omnipresence has become a public health concern we can no longer ignore.Going from the backstreets to Wall Street, Dines reveals how porn is affecting our lives and why its omnipresence is detrimental to our sexual freedom.

    Now Greene has once again mined history and literature to distill the essence of seduction, the most highly refined mode of influence, the ultimate power trip. The Art of Seduction is a masterful synthesis of the work of thinkers such as Freud, Ovid, Kierkegaard, and Einstein, as well as the achievements of the greatest seducers throughout history. From Cleopatra to John F. Kennedy, from Andy Warhol to Josephine Bonaparte, The Art of Seduction gets to the heart of the character of the seducer and his or her tactics, triumphs and failures. The seducer's many faces include: the Siren, the Rake, the Ideal Lover, the Dandy, the Natural, the Coquette, the Charmer, and the Charismatic. Twenty-four maneuvers will guide readers through the seduction process, providing cunning, amoral instructions for and analysis of this fascinating, all-pervasive form of power. Just as beautifully packaged and every bit as essential as The 48 Laws of Power, The Art of Seduction is an indispensable primer of persuasion and offers the best lessons on how to take what you want from whomever you want or how to prevent yourself from being taken.

    In Wicked Plants, Stewart takes on over two hundred of Mother Nature’s most appalling creations. It’s an A to Z of plants that kill, maim, intoxicate, and otherwise offend. You’ll learn which plants to avoid (like exploding shrubs), which plants make themselves exceedingly unwelcome (like the vine that ate the South), and which ones have been killing for centuries (like the weed that killed Abraham Lincoln's mother). Menacing botanical illustrations and splendidly ghastly drawings create a fascinating portrait of the evildoers that may be lurking in your own backyard. Drawing on history, medicine, science, and legend, this compendium of bloodcurdling botany will entertain, alarm, and enlighten even the most intrepid gardeners and nature lovers.

    Flow spans its fascinating, occasionally wacky and sometimes downright scary story: from mikvahs (ritual cleansing baths) to menopause, hysteria to hysterectomies—not to mention the Pill, cramps, the history of underwear, and the movie about puberty they showed you in 5th grade. Flow answers such questions as: What’s the point of getting a period? What did women do before pads and tampons? What about new drugs that promise to end periods—a hot idea or not? Sex during your period: gross or a turn-on? And what’s normal, anyway?  With color reproductions of (campy) historical ads and early (excruciating) femcare devices, it also provides a fascinating (and mind-boggling) gallery of this complex, personal and uniquely female process. As irreverent as it is informative, Flow gives an everyday occurrence its true props – and eradicates the stigma placed on it for centuries.
