Um livro de divulgação científica incrível, um dos melhores que já li, com uma exploração ao mesmo tempo imaginativa e fundamentada da relação da exploração científica do cosmos com os nosso problemas e necessidades terrenas. A imagem do pálido ponto azul, do início do livro, (da grande responsabilidade que temos perante a Terra dada à vastidão do universo), aparece inicialmente como uma imagem poderosa mas que não convence inteiramente, dado a aparência de salto e conexão rápida demais. Mas durante o livro ela vai se desdobrando em inúmeros argumentos e relações, ganhando corpo e efetividade. Da defesa de naves não tripuladas e exploração robótica; à descoberta dos CFCs, a especulações sobre frequências de rádio e vida inteligente, à discussão sobre recursos materiais extra-terrestres. Sagan consolida-se ao final, como um verdadeiro sábio: alguém que consegue fazer ciência, fazer política científica com o bem em vista e fazer divulgação científica inspiradora. Science books always run the risk of being outdated as new knowledge is gained. Pale Blue Dot was published back in the mid-1990's, which makes it ancient for the genre. As it turns out, not as much of the book was outdated as I feared. But the real reason I wanted to read it was because [a:Carl Sagan|10538|Carl Sagan|https://d.gr-assets.com/authors/1394121255p2/10538.jpg] is the prose poet nonpareil for science. His soaring, thoughtful turns of phrase are rarely matched by other science popularizers. There is a series of videos on You Tube, weaving Sagan's voice and writing (much of it from Pale Blue Dot) with images and wonderful music (https://www.youtube.com/playlist?list=PLF17F07CFC3208E29). While reading this book, I could hear Carl's voice distinctly. If you choose to read or re-read PBD, I encourage you to watch those videos first. Your reading will be the richer for it. 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. geen besprekingen | voeg een bespreking toe

"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 Geen bibliotheekbeschrijvingen gevonden. |

“Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions,
ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every
king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there -- on a
mote of dust suspended in a sunbeam.
The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely
distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.
Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there
is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.” Since global warming has become the clear and present danger of the day, the former has become ominous indeed. ( )
