All’inizio del XX secolo i fisici furono in grado di accostarsi per la prima volta al regno dell’estremamente piccolo, alla struttura ultima della materia e della radiazione. Quello che trovarono fu rivoluzionario e diede il via allo sviluppo di una nuova teoria fisica: la meccanica quantistica. Ma di che cosa si tratta? Perché serviva una nuova teoria? E che cosa c’è di così strano? Il comportamento della natura a livello fondamentale è caratterizzato dalla casualità, alla quale sono indissolubilmente legate le altre sorprendenti caratteristiche, come la quantizzazione, la sovrapposizione di stati, l’indeterminazione e il fenomeno dell’entanglement, ossia la correlazione quantistica tra due particelle spazialmente separate che produce effetti non locali (il celebre 'paradosso' di Einstein-Podolsky-Rosen). Questo libro mostra come la meccanica quantistica sia un tema affascinante che può essere compreso da chiunque e che fa riflettere su concetti come esistenza e individualità e, in ultima analisi, sul significato stesso della realtà.

La parola caos evoca l’eterna dicotomia tra ordine e disordine, tra luce e tenebre, tra conoscenza e ignoranza, tra nulla ed esistenza. Questo concetto è stato analizzato e interpretato secondo sei diverse prospettive, in un entusiasmante viaggio dall’origine dell’Universo. Dalla cosmologia alla teoria dell’informazione: la teoria di come dal nulla possa sorgere il tutto, a partire dal caos come assenza di forma, e il disordine della torre di Babele. Dalla termodinamica alla simmetria: il ruolo del caos nelle leggi della natura e il significato dell’asimmetria. Dai sistemi dinamici alla fisica quantistica: come l’idea di caos esprima il fatto che non siamo in grado di prevedere il risultato di determinati processi fisici, o che addirittura certi comportamenti fondamentali della natura sfuggano del tutto alla nostra possibilità di conoscenza. Per scoprire alla fine che, sorprendentemente ma non troppo, c’è un ordine anche nel caos.

Nobel Prize winner Werner Heisenberg's classic account explains the central ideas of the quantum revolution, and his celebrated Uncertainty Principle. The theme of Heisenberg's exposition is that words and concepts familiar in daily life can lose their meaning in the world of relativity and quantum physics. This in turn has profound philosophical implications for the nature of reality and for our total world view. 'It carries the reader, with remarkable clarity, from the esoteric world of atomic physics to the world of people, language and the conception of our shared reality' Paul Davies.

In a series of enlightening and wide-ranging discussions, all published here for the first time, Chomsky radically reinterprets the events of the past three decades, covering topics from foreign policy during Vietnam to the decline of welfare under the Clinton administration. And as he elucidates the connection between America's imperialistic foreign policy and the decline of domestic social services, Chomsky also discerns the necessary steps to take toward social change. With an eye to political activism and the media's role in popular struggle, as well as U.S. foreign and domestic policy, Understanding Power offers a sweeping critique of the world around us and is definitive Chomsky. Characterized by Chomsky's accessible and informative style, this is the ideal book for those new to his work as well as for those who have been listening for years.

The author of the international bestseller Silk now delivers a ravishing and wildly inventive novel about friendship, genius and its discontents, and the redemptive power of narrative. Somewhere in America lives a brilliant boy named Gould, an intellectual guided missile aimed at the Nobel Prize. His only companions are an imaginary giant and an imaginary mute. Improbably—and yet with impeccable logic--he falls into the care of Shatzy Shell, a young woman whose life up till that point has been equally devoid of human connection . Theirs is a relationship of stories and of stories within stories: of Gould’s evolving saga of an underdog boxer and the violent Western that Shatzy has been dictating into a tape recorder since the age of six. Out of these stories, Alessandro Baricco creates a masterpiece of metaphysical pulp fiction that recalls both Scheherazade and Italo Calvino. By turns exhilarating and deeply moving, City is irresistible.

"Again and again. . . I find myself being a Mrs. Bridge evangelist, telling them that it’s a perfect novel, and then pressing copies on them. . . What writing! Economical, piquant, beautiful, true." —Meg Wolitzer, The New York Times In Mrs. Bridge, Evan S. Connell, a consummate storyteller, artfully crafts a portrait using the finest of details in everyday events and confrontations. The novel is comprised of vignettes, images, fragments of conversations, events—all building powerfully toward the completed group portrait of a family, closely knit on the surface but deeply divided by loneliness, boredom, misunderstandings, isolation, sexual longing, and terminal isolation. In this special fiftieth anniversary edition, we are reminded once again why Mrs. Bridge has been hailed by readers and critics alike as one of the greatest novels in American literature.

The aim of this book is to introduce and explain important physical processes at the heart of the optical properties of semiconductor devices, such as light emitting diodes (LEDs) and semiconductor lasers. It is suitable for a half- semester (or a one-semester) course in Photonics or Optoelectronics at the graduate level in engineering physics, electrical engineering or material science. It offers an advanced analysis of the photo-physics of semiconductors, trying to avoid the use of exceedingly complex formalisms. Particular attention was devoted to offer a clear physical interpretation of all the obtained results. Various worked examples are added throughout all the chapters to illustrate the application of the various formulas discussed in the text.The book covers fundamental aspects of solid state physics, relevant for the calculation and analysis of semiconductor band-structure, and of quantum mechanics of electron-photon interaction. The photo-physics of bulk and quantum well semiconductors are discussed in detail. The final five chapters analyse the physics and properties of important photonic devices: light- emitting diodes (LEDs) and lasers, including Distributed Feedback (DFB) lasers, Vertical-Cavity Surface-Emitting Lasers (VCSELs) and Quantum Cascade Lasers. The general philosophy adopted in these chapters is the following: the fundamental physical processes are investigated, rather than the technological characteristics of the devices.

Quantum Mind. The Edge Between Physics and Psychology This is the second edition with new preface from the author. In a single volume, Arnold Mindell brings together psychology, physics, math, myth, and shamanism – not only mapping the way for next-generation science but also applying this wisdom to personal growth, group dynamics, social and political processes, and environmental issues. Beginning with a discussion of cultural impacts on mathematics, he presents esoteric but plausible interpretations of imaginary numbers and the quantum wavefunction. In this context he discusses dreams, psychology, illness, shape-shifting (moving among realities), and the self-reflecting Universe – bringing in not only shamanism but also the Aboriginal, Greek, and Hindu myths and even sacred geometry from the Masonic orders and the Native Americans. The book is enriched by several psychological exercises that enable the reader to subjectively experience mathematics (counting, discounting, squaring, complex conjugating), physics (parallel worlds, time travel), and shamanism (shape-shifting).

The two protagonists who are as different as chalk from cheese. The charismatic dare-devil Guido, though endowed with immense personal charm, and innate abilities as a leader of men (as well as being the darling of all the girls), is subtly flawed, and unable to match his own significant aspirations. Guido’s prophetic idealism, and his frustrated attempts to escape his lower-class origins and change the world, nevertheless seem doomed to failure. He eventually writes a best-selling book, highly acclaimed by the critics, in which he condemns the social mores of the Italian seventies—corruption, terrorism, bombs and anarchy. Although, through his novel, he is initially acclaimed as a prophet of sorts, he predictably falls victim to vitriolic, self-serving critics who enjoy demolishing him. Eventually, despite his enormous talent, Guido will remain an eternal dreamer; whereas his closest friend who has always depended on him—the insecure narrator, Mario, always the more practical and circumspect of the two—will finally learn to actualize his own dreams, helping to change the world through actualizing his own dream of authenticity. Meanwhile, the alienated Guido will succumb to his own inevitable destiny.

The Dickinson Statement brings clarity to fluoridation and fluorides. Ian Edward Stephens, a trained mechanical engineer, was a deeply passionate man concerned with issues of health. Here he illuminates some hidden history and intrigue surrounding fluoride, an important industrial chemical. Originally self-published in 1987, his booklet has been available on the Internet since the mid 1990s and has altered many people's perceptions and lives. The second half reveals the deadly nature of the fluoride compounds that have afflicted many deeply without them ever suspecting the cause of their troubles. While the subject itself is technical in nature, Ian has made the ideas accessible to all with his forthright and engaging writing style. He adds a dash of humour when it's least expected. By airing fluoride's 'dirty laundry', Ian forewarns readers about passively accepting any fluoride chemicals or compounds as "safe and effective". It's only when we discover this crucial information, rarely seen in the mass media, that we can make fully informed choices on the subject. The adage "information is power" has never been more true. This 25th anniversary expanded edition may well improve the quality of your health and life, giving you the facts and allowing you, the reader, and indeed all of us to get on with protecting ourselves and the ones we love from unnecessary harm. To the late Ian E Stephens, we are forever grateful.

NAMED ONE OF THE BEST BOOKS OF THE YEAR BY KIRKUS REVIEWS In a memoir of family bonding and cutting-edge physics for readers of Brian Greene’s The Hidden Reality and Jim Holt’s Why Does the World Exist?, Amanda Gefter tells the story of how she conned her way into a career as a science journalist—and wound up hanging out, talking shop, and butting heads with the world’s most brilliant minds. At a Chinese restaurant outside of Philadelphia, a father asks his fifteen-year-old daughter a deceptively simple question: “How would you define nothing?” With that, the girl who once tried to fail geometry as a conscientious objector starts reading up on general relativity and quantum mechanics, as she and her dad embark on a life-altering quest for the answers to the universe’s greatest mysteries. Before Amanda Gefter became an accomplished science writer, she was a twenty-one-year-old magazine assistant willing to sneak her and her father, Warren, into a conference devoted to their physics hero, John Wheeler. Posing as journalists, Amanda and Warren met Wheeler, who offered them cryptic clues to the nature of reality: The universe is a self-excited circuit, he said. And, The boundary of a boundary is zero. Baffled, Amanda and Warren vowed to decode the phrases—and with them, the enigmas of existence. When we solve all that, they agreed, we’ll write a book. Trespassing on Einstein’s Lawn is that book, a memoir of the impassioned hunt that takes Amanda and her father from New York to London to Los Alamos. Along the way, they bump up against quirky science and even quirkier personalities, including Leonard Susskind, the former Bronx plumber who invented string theory; Ed Witten, the soft-spoken genius who coined the enigmatic M-theory; even Stephen Hawking. What they discover is extraordinary: the beginnings of a monumental paradigm shift in cosmology, from a single universe we all share to a splintered reality in which each observer has her own. Reality, the Gefters learn, is radically observer-dependent, far beyond anything of which Einstein or the founders of quantum mechanics ever dreamed—with shattering consequences for our understanding of the universe’s origin. And somehow it all ties back to that conversation, to that Chinese restaurant, and to the true meaning of nothing. Throughout their journey, Amanda struggles to make sense of her own life—as her journalism career transforms from illusion to reality, as she searches for her voice as a writer, as she steps from a universe shared with her father to at last carve out one of her own. It’s a paradigm shift you might call growing up. By turns hilarious, moving, irreverent, and profound, Trespassing on Einstein’s Lawn weaves together story and science in remarkable ways. By the end, you will never look at the universe the same way again. Praise for Trespassing on Einstein’s Lawn “Nothing quite prepared me for this book. Wow. Reading it, I alternated between depression—how could the rest of us science writers ever match this?—and exhilaration.”—Scientific American “To Do: Read Trespassing on Einstein’s Lawn. Reality doesn’t have to bite.”—New York “A zany superposition of genres . . . It’s at once a coming-of-age chronicle and a father-daughter road trip to the far reaches of this universe and 10,500 others.”—The Philadelphia Inquirer From the Hardcover edition.

John McEnroe stunned the tennis elite when he came out of nowhere to make the Wimbledon semifinals at the age of eighteen—and just a few years later, he was ranked number one in the world. You Cannot Be Serious is McEnroe at his most personal, a no-holds-barred examination of Johnny Mac, the kid from Queens, and his “wild ride” through the world of professional tennis at a boom time when players were treated like rock stars. Here he candidly explores the roots of his famous on-court explosions; his ambivalence toward the sport that made him famous; his adventures (and misadventures) on the road; his views of colleagues from Connors to Borg to Lendl; his opinions of contemporary tennis—and his current roles as husband, father, senior tour player, and often-controversial commentator—in a “bracing new serve-and-volley autobiography” (The Boston Globe).
