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.

The question we will always be asking but will never know the answer is the question: Is there life in Outer Space? I think that almost every thinking person believes that life exists out there somewhere? But finding life is almost meaningless unless we can find intelligent life that can communicate with us. And for what purpose? We now know that it is almost certain that chemical spores can be created and if enough of them come together life can form. For life to have meaning, it must be able to reproduce itself and to create more of them.

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.

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.

¿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

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

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

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.»

In his charmingly down-to-earth voice, the late astronomer Carl Sagan discusses the relationship between religion and science and describes his own personal search to understand the nature of the sacred in the vastness of the cosmos.

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.

Por que gastar fortunas com programas espaciais quando há tantos problemas aguardando solução a poucos metros de nossas casas? Para Sagan, um dia o conhecimento do espaço poderá significar nossa sobrevivência como espécie. ''Pálido ponto azul'' revela como as descobertas científicas alteraram nossa percepção de quem somos e do lugar que ocupamos no Universo - e nos incita a refletir sobre o uso que daremos a esse conhecimento.

An analysis of the potentially devastating consequences of nuclear war discusses the environmental impact of nuclear winter and proposes changes in international nuclear policies

Stephen Hawking has earned a reputation as the most brilliant theoretical physicist since Einstein. In this landmark volume, Professor Hawking shares his blazing intellect with nonscientists everywhere, guiding us expertly to confront the supreme questions of the nature of time and the universe. Was there a beginning of time? Will there be an end? Is the universe infinite or does it have boundaries? From Galileo and Newton to modern astrophysics, from the breathtakingly cast to the extraordinarily tiny, Professor Hawking leads us on an exhilarating journey to distant galaxies, black holes, alternate dimensions--as close as man has ever ventured to the mind of God. From the vantage point of the wheelchair from which he has spent more than twenty years trapped by Lou Gehrig''s disease, Stephen Hawking has transformed our view of the universe. Cogently explained, passionately revealed, "A Brief History of Time is the story of the ultimate quest for knowledge: the ongoing search for the tantalizing secrets at the heart of time and space.

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
