Book Description
The thought experiment proposed by Langevin in 1911, known under the popular names, 'Clock Paradox' or 'Twin Paradox', is the most surprising result of the theory of Relativity: A twin who travels to a star at nearly the velocity of light comes back to Earth and finds his twin brother much older. In over a century, several thousands of published articles debated both in favor of and against this result. Unique to the physics of Relativity, this baffling phenomenon is analyzed as a main goal of this book.Among an incredible number of solutions, is there one of simplicity and clarity which may be accepted unanimously by all of the physics community? The answer is yes and this solution, which has its origin in Einstein himself, is developed in the framework of the Special Theory of Relativity. In detailing this solution, it is shown that the essential ingredient to understand the theory is the acceleration of the twins. All the models which do not include acceleration are incompatible with the original idea of Langevin. If one considers this phenomenon, several questions come to mind. Why did physicists debate excessively on the paradox and struggle to reach an agreement? Why was there resistance to integrate acceleration into their studies? Why is the solution developed in this book known only by a minority of scientists?Written for physicists, historians and philosophers of science, this book seeks to answer these questions based on (1) the psychological difficulty to accept the theoretical results, and (2) the fact that scientific knowledge is not uniformly distributed among scientists.

Book Description
THE STORY BEHIND THE FILM TWINSTERS One of the Top Ten Facebook Stories of the decade When twenty-five-year-old South Korean adoptee and actress Samantha Futerman opened a Facebook message from a stranger named Anaïs Bordier, she had no idea that it would change her life forever… Adopted from South Korea as an infant, Sam grew up in New Jersey with her parents and two brothers. She never imagined she had a sister; nor did Anaïs—who grew up in France and was also adopted from South Korea—until she saw an actress with a face identical to her own in a YouTube video and decided to contact her doppelgänger via social media. A few dubious exchanges turned from mistrust and cynicism to utter shock, as the women discovered more in common than just their looks—and their birth date. Samantha and Anaïs’s ensuing adventure is a dive into the fascinating research on identical twins, particularly those who have been separated since birth; a reexamination of nature vs. nurture; a guide through the often befuddling territory of foreign adoption; and an emotional soul-search for two inextricably connected set of parents and children. Their discovery can only be described as the unimaginable journey of a lifetime—one that spans languages, continents, cultures, and ultimately proves that none of these barriers can disrupt the unbreakable bond between sisters.

Book Description
"[Dieterich's] writing is crisp and intelligent . . . She writes about her own reckoning with her sexuality and exploration of queer identity without becoming pat or coy, giving readers intimate access to her fears and conflicting emotions." --NPR For as long as she can remember, Leah has had the mysterious feeling that she’s been searching for a twin--that she should be part of an intimate pair. It begins with dance partners as she studies ballet growing up; continues with her attractions to girlfriends in college; and leads her, finally, to Eric, whom she moves across the country for and marries. But her steadfast, monogamous relationship leaves her with questions about her sexuality and her identity, so she and her husband decide to try an open marriage. How does a young couple make room for their individual desires, their evolving selfhoods, and their artistic ambitions while building a life together? Can they pursue other sexual partners, even live in separate cities, and keep their original passionate bond alive? Vanishing Twins looks for answers in psychology, science, pop culture, art, architecture, Greek mythology, dance, and language to create a lucid, suspenseful portrait of a woman testing the limits and fluidities of love.

Beneath their perfect family façade, twin sisters struggle alone with impossible circumstances and their own demons until they finally learn to fight for each other in this poignant tour de force from #1 New York Times bestselling author Ellen Hopkins. Sixteen-year-old Kaeleigh and Raeanne are identical down to the dimple. As daughters of a district court judge father and a politician mother, they are an all-American family…on the surface. Underneath run very deep and damaging secrets. What really happened in the car accident that Daddy caused? And why is Mom never home, always running far away to pursue some new dream? The girls themselves have become hopelessly divided over the years. Sick of losing Daddy’s game of favorites, Raeanne turns to painkillers, alcohol, and sex to dull her pain her anger. Kaeleigh tries to be her father’s perfect little flower, but being the misplaced focus of his sexual attention has her seeking control anywhere she can—even if it means cutting herself and unhealthy binge and purge eating. Secrets like the ones the twins are harboring are not meant to be kept—from each other or anyone else.

Book Description
With his stunning debut novel, She's Come Undone, Wally Lamb won the adulation of critics and readers with his mesmerizing tale of one woman's painful yet triumphant journey of self-discovery. Now, this brilliantly talented writer returns with I Know This Much Is True, a heartbreaking and poignant multigenerational saga of the reproductive bonds of destruction and the powerful force of forgiveness. A masterpiece that breathtakingly tells a story of alienation and connection, power and abuse, devastation and renewal--this novel is a contemporary retelling of an ancient Hindu myth. A proud king must confront his demons to achieve salvation. Change yourself, the myth instructs, and you will inhabit a renovated world. When you're the same brother of a schizophrenic identical twin, the tricky thing about saving yourself is the blood it leaves on your bands--the little inconvenience of the look-alike corpse at your feet. And if you're into both survival of the fittest and being your brother's keeper--if you've promised your dying mother--then say so long to sleep and hello to the middle of the night. Grab a book or a beer. Get used to Letterman's gap-toothed smile of the absurd, or the view of the bedroom ceiling, or the influence of random selection. Take it from a godless insomniac. Take it from the uncrazy twin--the guy who beat the biochemical rap. Dominick Birdsey's entire life has been compromised and constricted by anger and fear, by the paranoid schizophrenic twin brother he both deeply loves and resents, and by the past they shared with their adoptive father, Ray, a spit-and-polish ex-Navy man (the five-foot-six-inch sleeping giant who snoozed upstairs weekdays in the spare room and built submarines at night), and their long-suffering mother, Concettina, a timid woman with a harelip that made her shy and self-conscious: She holds a loose fist to her face to cover her defective mouth--her perpetual apology to the world for a birth defect over which she'd had no control. Born in the waning moments of 1949 and the opening minutes of 1950, the twins are physical mirror images who grow into separate yet connected entities: the seemingly strong and protective yet fearful Dominick, his mother's watchful "monkey"; and the seemingly weak and sweet yet noble Thomas, his mother's gentle "bunny." From childhood, Dominick fights for both separation and wholeness--and ultimately self-protection--in a house of fear dominated by Ray, a bully who abuses his power over these stepsons whose biological father is a mystery. I was still afraid of his anger but saw how he punished weakness--pounced on it. Out of self-preservation I hid my fear, Dominick confesses. As for Thomas, he just never knew how to play defense. He just didn't get it. But Dominick's talent for survival comes at an enormous cost, including the breakup of his marriage to the warm, beautiful Dessa, whom he still loves. And it will be put to the ultimate test when Thomas, a Bible-spouting zealot, commits an unthinkable act that threatens the tenuous balance of both his and Dominick's lives. To save himself, Dominick must confront not only the pain of his past but the dark secrets he has locked deep within himself, and the sins of his ancestors--a quest that will lead him beyond the confines of his blue-collar New England town to the volcanic foothills of Sicily 's Mount Etna, where his ambitious and vengefully proud grandfather and a namesake Domenico Tempesta, the sostegno del famiglia, was born. Each of the stories Ma told us about Papa reinforced the message that he was the boss, that he ruled the roost, that what he said went. Searching for answers, Dominick turns to the whispers of the dead, to the pages of his grandfather's handwritten memoir, The History of Domenico Onofrio Tempesta, a Great Man from Humble Beginnings. Rendered with touches of magic realism, Domenico's fablelike tale--in which monkeys enchant and religious statues weep--becomes the old man's confession--an unwitting legacy of contrition that reveals the truth's of Domenico's life, Dominick learns that power, wrongly used, defeats the oppressor as well as the oppressed, and now, picking through the humble shards of his deconstructed life, he will search for the courage and love to forgive, to expiate his and his ancestors' transgressions, and finally to rebuild himself beyond the haunted shadow of his twin. Set against the vivid panoply of twentieth-century America and filled with richly drawn, memorable characters, this deeply moving and thoroughly satisfying novel brings to light humanity's deepest needs and fears, our aloneness, our desire for love and acceptance, our struggle to survive at all costs. Joyous, mystical, and exquisitely written, I Know This Much Is True is an extraordinary reading experience that will leave no reader untouched.
