New Releases by Carl Sagan

Como reagiríamos ao travar contato com uma civilização extraterrestre? Sobre essa incógnita, Sagan tece uma história que indaga acerca do encontro entre os homens e do indivíduo consigo mesmo. Contato com extraterrestres não é sinônimo de homenzinhos verdes desembarcando de um disco voador. É muito mais: sinais captados num radiotelescópio podem conter mensagens capazes de nos fazer repensar toda a nossa concepção da vida e do universo. Esse é o ponto de partida de Carl Sagan, que, aliando as tensões da melhor literatura ao conhecimento científico mais avançado, compõe um romance que pode provocar em nós todas as reações - menos a indiferença. Em Contato, o que está em jogo é o mundo tal como o conhecemos. Como quem faz uma aposta, Sagan nos convida a uma viagem assustadoramente fascinante pelo buraco negro que é a inteligência humana.

Telah lama manusia membayangkan kehidupan di luar Bumi. Para ilmuwan tak lelah mencari tanda-tandanya di segala penjuru langit. Bertahun-tahun Proyek Argus dengan teleskop-teleskop radionya berusaha menangkap sinyal yang menandakan keberadaaan kehidupan cerdas di alam semesta. Pada suatu sore, sejarah umat manusia berubah, untuk seketika dan selamanya. Suatu Pesan yang telah menunggu lama, yang keberadaannya diragukan, akhirnya tiba. Kontak telah terjadi. Suatu kehidupan, seseorang, sesuatu di dekat bintang Vega, 26 tahun cahaya jauhnya dari Bumi, memanggil-manggil kita, memancarkan pesan yang menyatakan bahwa selama ini kita tidak sendiri. Dr. Eleanor Arroway, direktur Proyek Argus, dialah yang pertama kali menyadari bahwa babak pertama sejarah umat manusia telah berakhir. Dialah yang menerjemahkan Pesan dan meyakinkan para kepala negara agar tidak memperlakukan Pesan itu sebagai ancaman. Pada tiap langkah yang dia ambil, tidak hanya Ellie mengalami kontak dengan yang extraterrestrial, tapi ia pun melakukan perjalanan yang jauh lebih bermakna ke dalam dirinya sendiri. Kontak pertama kali diterbitkan pada 1985, setelah Dr. Carl Sagan menulis Kosmos, buku sainsnya yang populer. Bila dalam Kosmos Dr. Sagan menjelaskan alam semesta; dalam Kontak ia memprediksi masa depan alam semestaÑdan umat manusia.

Numa série de palestras proferidas em 1985, o astrofísico Carl Sagan discute a existência de Deus, expõe suas esperanças de encontrar vida inteligente em outros planetas e manifesta o desejo de que a religião seja usada para melhorar a vida do ser humano. Mais de vinte anos antes do atual movimento ateísta, o astrofísico Carl Sagan questionava a visão tradicional de Deus num tom bem-humorado, de sólidas bases científicas, nas Palestras Gifford, promovidas pela Universidade de Glasgow em 1985 para discutir a "teologia natural". A relevância do tema na atualidade, marcada pelo extremismo religioso de todos os matizes, fez com que sua viúva e colaboradora Ann Druyan recuperasse as transcrições perdidas das conferências e as transformasse no livro Variedades da experiência científica: uma visão pessoal da busca por Deus. Como grande divulgador da ciência, Sagan tinha o dom de falar simples, mesmo se estivesse explicando mecânica quântica. Nas palestras, ressalta a predisposição do ser humano para acreditar nas coisas e relata equívocos históricos como a descrição dos enormes canais de Marte, no início do século XX. Mesmo refutando a visão de Deus como um "homem grande de barbas brancas e compridas sentado num trono no céu e controlando o vôo de cada andorinha", o astrônomo não descarta a existência de alguma forma de inteligência superior, e abre uma detalhada discussão sobre a inteligência extraterrestre. Ao contrário dos líderes do movimento ateísta, Sagan não menospreza toda e qualquer forma de religião. Para ele, as religiões podem desempenhar o útil papel de orientar o comportamento humano. O que critica é o fato de elas fazerem afirmações sobre ciência sem usar o método científico do ceticismo e da autocorreção. Segundo sua viúva, Ann Druyan, organizar a edição das palestras ofereceu-lhe a "maravilhosa impressão de que havíamos de alguma maneira sido transportados de volta para as duas sublimes décadas em que pensávamos e escrevíamos juntos". Variedades da experiência científica estende ao leitor a oportunidade de voltar a aprender com Sagan, um homem que foi, em sua própria descrição, um cidadão do cosmos.

El hombre se ha planteado siempre profundos interrogantes sobre los orígenes de la conciencia, la vida sobre nuestro planeta, los primeros tiempos de la Tierra, el origen del Sol, la posibilidad de vida inteligente en algún otro lugar del cosmos o el destino último del Universo. Este libro trata de dar soluciones a estos interrogantes. Su autor tiene la rara habilidad de contagiar su entusiasmo por cuanto se ha descubierto sobre el Universo en los últimos años y por cuanto hemos aprendido sobre nuestro propio entorno. Desde una perspectiva científica, el autor compone este libro alrededor de tres grandes figuras: Paul Broca, el insigne neurólogo francés del siglo XIX; Robert Goddard, padre de la moderna exploración espacial, y Albert Einstein, fundador de la física moderna. A través de sus brillantes páginas, el lector se va adentrando, poco a poco, en la compleja maquinaria del Universo, en el apasionante mundo de la ciencia.

Contacto es la única novela escrita por el astrónomo estadounidense Carl Sagan, uno de los mayores divulgadores científicos del siglo XX. Tras cinco años de incesantes búsquedas con los dispositivos más sofisticados del momento, la astrónoma Eleanor Arroway consigue, junto a un equipo de científicos internacionales, conectar con la estrella Vega y demostrar que no estamos solos en el universo. Empieza entonces un trepidante viaje hacia el encuentro más esperado de la historia de la humanidad, y con él Carl Sagan plantea magistralmente cómo afectaría a nuestra sociedad la recepción de mensajes de una civilización inteligente. Contacto, Premio Locus 1986, desarrolla una de las constantes en la trayectoria del autor: la búsqueda de inteligencia extraterrestre y la comunicación con ella a través de sondas espaciales. En 1997, el director de cine Robert Zemeckisllevó esta historia a la gran pantalla, en una película protagonizada por Jodie Foster y Matthew McConaughey.

Cosmos trata de la ciencia en su contexto humano m�s amplio y explica c�mo la ciencia y la civilizaci�n se desarrollan conjuntamente.

¿Estamos al borde de una nueva edad oscura de irracionalismo y superstición? En este libro conmovedor, el incomparable Carl Sagan demuestra con brillantez que el pensamiento científico es necesario para salvaguardar nuestras instituciones democráticas y nuestra civilización técnica. El mundo y sus demonios es el libro más personal de Sagan, y está lleno de historias humanas entrañables y reveladoras. El autor, con las experiencias de su propia infancia y la apasionante historia de los descubrimientos de la ciencia, muestra cómo el método del pensamiento racional puede superar prejuicios y supersticiones para dejar al descubierto la verdad, que, con frecuencia, resulta sorprendente.

Este libro, est� basado en un programa de trece cap�tulos que el profesor Carl Sagan realiz� para la televisi�n. Narrado con la proverbial habilidad que ten�a Sagan para conseguir que las ideas cient�ficas fuesen comprensibles y apasionantes

Renowned astronomer Carl Sagan’s classic bestseller that “dives into the past, present, and future of science, dealing with the mind-staggering enormity of the cosmos in which we exist” (Associated Press)—with an Introduction by Ann Druyan and a Foreword by Neil deGrasse Tyson “Sagan dazzles the mind with the miracle of our survival, framed by the stately galaxies of space.”—Cosmopolitan THE INSPIRATION FOR THE FOX MINISERIES COSMOS: POSSIBLE WORLDS, HOSTED BY NEIL DEGRASSE TYSON AND STARRING SETH MACFARLANE AND SIR PATRICK STEWART In clear-eyed prose, Carl Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space. Featuring full-color illustrations, Cosmos retraces the fourteen billion years of cosmic evolution that have transformed matter into consciousness, exploring such topics as the origin of life, the human brain, Egyptian hieroglyphics, spacecraft missions, the death of the Sun, the evolution of galaxies, and the forces and individuals who helped shape modern science.

NEW YORK TIMES BESTSELLER • In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century? Here, too, is a rare, private glimpse of Sagan’s thoughts about love, death, and God as he struggled with fatal disease. Ever forward-looking and vibrant with the sparkle of his unquenchable curiosity, Billions & Billions is a testament to one of the great scientific minds of our day. Praise for Billions & Billions “[Sagan’s] writing brims with optimism, clarity and compassion.”—Ft. Lauderdale Sun-Sentinel “Sagan used the spotlight of his fame to illuminate the abyss into which stupidity, greed, and the lust for power may yet dump us. All of those interests and causes are handsomely represented in Billions & Billions.”—The Washington Post Book World “Astronomer Carl Sagan didn’t live to see the millennium, but he probably has done more than any other popular scientist to prepare us for its arrival.”—Atlanta Journal & Constitution “Billions & Billions can be interpreted as the Silent Spring for the current generation. . . . Human history includes a number of leaders with great minds who gave us theories about our universe and origins that ran contrary to religious dogma. Galileo determined that the Earth revolved around the Sun, not the other way around. Darwin challenged Creationism with his Evolution of Species. And now, Sagan has given the world its latest challenge: Billions & Billions.”—San Antonio Express-News “[Sagan’s] inspiration and boundless curiosity live on in the gift of his work.”—Seattle Times & Post-Intelligencer “Couldn’t stay awake in your high school science classes? This book can help fill in the holes. Acclaimed scientist Carl Sagan combines his logic and knowledge with wit and humor to make a potentially dry subject enjoyable to read.”—The Dallas Morning News

“Fascinating . . . memorable . . . revealing . . . perhaps the best of Carl Sagan’s books.”—The Washington Post Book World (front page review) In Cosmos, the late astronomer Carl Sagan cast his gaze over the magnificent mystery of the Universe and made it accessible to millions of people around the world. Now in this stunning sequel, Carl Sagan completes his revolutionary journey through space and time. Future generations will look back on our epoch as the time when the human race finally broke into a radically new frontier—space. In Pale Blue Dot, Sagan traces the spellbinding history of our launch into the cosmos and assesses the future that looms before us as we move out into our own solar system and on to distant galaxies beyond. The exploration and eventual settlement of other worlds is neither a fantasy nor luxury, insists Sagan, but rather a necessary condition for the survival of the human race. “Takes readers far beyond Cosmos . . . Sagan sees humanity’s future in the stars.”—Chicago Tribune

What are these graceful visitors to our skies? We now know that they bring both life and death and teach us about our origins. Comet begins with a breathtaking journey through space astride a comet. Pulitzer Prize-winning astronomer Carl Sagan, author of Cosmos and Contact, and writer Ann Druyan explore the origin, nature, and future of comets, and the exotic myths and portents attached to them. The authors show how comets have spurred some of the great discoveries in the history of science and raise intriguing questions about these brilliant visitors from the interstellar dark. Were the fates of the dinosaurs and the origins of humans tied to the wanderings of a comet? Are comets the building blocks from which worlds are formed? Lavishly illustrated with photographs and specially commissioned full-color paintings, Comet is an enthralling adventure, indispensable for anyone who has ever gazed up at the heavens and wondered why. Praise for Comet "Simply the best." —The Times of London "Fascinating, evocative, inspiring." —The Washington Post "Comet humanizes science. A beautiful, interesting book." —United Press International "Masterful . . . science, poetry, and imagination." —The Atlanta Journal & Constitution

NATIONAL BESTSELLER • “Exciting and provocative . . . A tour de force of a book that begs to be seen as well as to be read.”—The Washington Post Book World World renowned scientist Carl Sagan and acclaimed author Ann Druyan have written a Roots for the human species, a lucid and riveting account of how humans got to be the way we are. Shadows of Forgotten Ancestors is a thrilling saga that starts with the origin of the Earth. It shows with humor and drama that many of our key traits—self-awareness, technology, family ties, submission to authority, hatred for those a little different from ourselves, reason, and ethics—are rooted in the deep past, and illuminated by our kinship with other animals. Sagan and Druyan conduct a breathtaking journey through space and time, zeroing in on critical turning points in evolutionary history, and tracing the origins of sex, altruism, violence, rape, and dominance. Their book culminates in a stunningly original examination of the connection between primate and human traits. Astonishing in its scope, brilliant in its insights, and an absolutely compelling read, Shadows of Forgotten Ancestors is a triumph of popular science.

A fascinating book on the joys of discovering how the world works, by the Pulitzer Prize–winning author of Cosmos and Shadows of Forgotten Ancestors. “Magnificent . . . Delightful . . . A masterpiece. A message of tremendous hope for humanity . . . While ever conscious that human folly can terminate man’s march into the future, Sagan nonetheless paints for us a mind-boggling future: intelligent robots, the discovery of extraterrestrial life and its consequences, and above all the challenge and pursuit of the mystery of the universe.”—Chicago Tribune “Go out and buy this book, because Carl Sagan is not only one of the world’s most respected scientists, he’s a great writer. . . . I can give a book no greater accolade than to say I’m planning on reading it again. And again. And again.”—The Miami Herald “The brilliant astronomer . . . is persuasive, provocative and readable.”—United Press International “Closely reasoned, impeccably researched, gently humorous, utterly devastating.”—The Washington Post

En esta obra póstuma Carl Sagan combina magistralmente astronomía, física, biología, filosofía y teología para explicar nuestra experiencia del universo y de ese sentimiento casi místico que todos experimentamos al admirarlo. Con un estilo simple y directo, sin academicismos ni tecnicismos, el autor aborda los temas clave de su obra: la relación entre ciencia y religión, el origen del universo, las posibilidades de vida extraterrestre, el destino de la humanidad, entre otros. Sus inteligentes observaciones -en muchas ocasiones, asombrosamente proféticas- sobre los grandes misterios del cosmos tienen el efecto vigorizador de estimular el intelecto, la imaginación y despertarnos a la grandeza de la vida en el cosmos. La diversidad de la ciencia. Una visión personal de la búsqueda de Dios se publica ahora por primera vez en conmemoración del décimo aniversario de la muerte de Sagan, y ha sido editado y actualizado por su viuda y colaboradora Ann Druyan.

“Ann Druyan has unearthed a treasure. It is a treasure of reason, compassion, and scientific awe. It should be the next book you read.” —Sam Harris, author of The End of Faith “A stunningly valuable legacy left to all of us by a great human being. I miss him so.” —Kurt Vonnegut Carl Sagan''s prophetic vision of the tragic resurgence of fundamentalism and the hope-filled potential of the next great development in human spirituality The late great astronomer and astrophysicist describes his personal search to understand the nature of the sacred in the vastness of the cosmos. Exhibiting a breadth of intellect nothing short of astounding, Sagan presents his views on a wide range of topics, including the likelihood of intelligent life on other planets, creationism and so-called intelligent design, and a new concept of science as "informed worship." Originally presented at the centennial celebration of the famous Gifford Lectures in Scotland in 1985 but never published, this book offers a unique encounter with one of the most remarkable minds of the twentieth century.

Los dragones del Edén es un libro mítico, publicado por vez primera en 1977 y galardonado con el premio Pulitzer. Casi treinta años después, conserva toda su frescura e interés. En una impresionante ojeada panorámica que abarca desde la prehistoria hasta la época actual, Carl Sagan explica la evolución intelectual y mental del ser humano, habla de nuestros antepasados y sus antagonistas, describe la mecánica de nuestro cerebro y del de otros animales y dilucida el papel que han desempeñado los ordenadores en el conocimiento de los mecanismos de nuestro cerebro y en el almacenamiento de la información en nuestra memoria. Hallamos también en estas páginas fascinantes incursiones en los terrenos del mito y la leyenda, así como atrevidas especulaciones sobre los cauces futuros por los que parece va a discurrir la evolución del hombre. Isaac Asimos dijo de este libro: «Carl Sagan posee el toque del rey Midas Nunca había leído hasta ahora un relato tan interesante y cautivador sobre el tema de la inteligencia humana.»

Assombrado com as explicações pseudocientíficas e místicas que ocupam cada vez mais os espaços dos meios de comunicação, Carl Sagan reafirma o poder positivo e benéfico da ciência e da tecnologia para iluminar os dias de hoje e recuperar os valores da racionalidade. Como todos os livros do autor, O mundo assombrado pelos demônios está cheio de informações surpreendentes, transmitidas com humor e graça. Seus ataques muitas vezes divertidos à falsa ciência, às concepções excêntricas e aos irracionalismos do momento são acompanhados por lembranças da infância, quando seus pais o colocaram em contato pela primeira vez com os dois modelos de pensamento fundamentais para o método científico: o ceticismo e a admiração.

La obra mas completa de divulgacion cientifica de todos los tiempos. En Un punto azul palido, Carl Sagan prosigue el espectacular viaje cientifico que inicio Cosmos, el libro que hizo descender a la Tierra la magnificencia del universo, haciendola accesible a millones de personas. Cosmos ha sido el libro cientifico mas vendido de la historia. En esta continuacion de Cosmos, Carl Sagan, ganador del Premio Pulitzer nos brinda una emocionante vision del universo, ilustrada profusamente. "Un punto azul palido" revela como la ciencia ha revolucionado nuestra comprension de donde estamos y de quienes somos, y nos desafia a que valoremos de que manera vamos a utilizar esos conocimientos.

A classic book by the world''s most famous scientist and science visionary, back in print with a new perspective.

NEW YORK TIMES BESTSELLER • From the renowned astronomer and author of Cosmos comes a “powerful [and] stirring defense of informed rationality” (The Washington Post Book World) in a world where fake news stories and Internet conspiracy theories play to a disaffected American populace. LOS ANGELES TIMES BOOK PRIZE WINNER • “Glorious . . . A spirited defense of science . . . From the first page to the last, this book is a manifesto for clear thought.”—Los Angeles Times How can we make intelligent decisions about our increasingly technology-driven lives if we don’t understand the difference between the myths of pseudoscience, New Age thinking, and fundamentalist zealotry and the testable hypotheses of science? Casting a wide net through history and culture, Pulitzer Prize–winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions. He examines and authoritatively debunks such celebrated fallacies as witchcraft, faith healings, demons, and UFOs. And yet, disturbingly, in today’s so-called information age, pseudoscience is burgeoning, with stories of alien abduction, “channeling” past lives, and communal hallucinations commanding growing attention and respect. As Sagan demonstrates with lucid eloquence, the siren song of unreason is not just a cultural wrong turn but a dangerous plunge into darkness that threatens our most basic freedoms.

In Billions and Billions, Carl Sagan demonstrates his incredible ability to cut through the jargon and misinformation to help us make sense of the world around us as it prepares for the challenges of the coming millennium.
