Pale Blue Dot: A Vision of the Human Future in Space (عالم المعرفة #254)
Photos, many in color.
Even though our ingrained geo-centric and ethno-centric biases cause us to become deflated and even depressed at the real...more
Besides his beautiful evocative descriptions of moons and worlds in our own Solar system, Sagan gave us a surplus of inspirational and cautionary passages in this work which--even as an adult--make you want to grow up to be an astronaut.
"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...more
This nonfiction masterpiece begins by pointing out the ramifications of the "pale blue dot" photograph taken by the Voyager in 1990, from a further distance than had ever before been seen. He logically speculates about the futility of wars over religious differences, land, extreme nationalism, and political conflict, when it comes to the bigg...more

In a tour of our solar system, galaxy and beyond, Cornell astronomer Sagan meshes a history of astronomical discovery, a cogent brief for space exploration and an overview of life-from its origins in the oceans to humanity's first emergence to a projected future where humans "terraform" and settle other planets and asteroids, Earth having long been swallowed by the sun. Maintaining that such relocation is inevitable, the author further argues that planetary science is of
The book stays clear of complex science but engages the reader to consider planetary geology, climatology and the possibility of alien biology. But most of all, Sagan's view is that of the impassioned observer who cares deeply about his subject, not just as an intellectual matter, but as something that has significance for our wellbeing, and perhaps s...more
Best one from Carl Sagan(about earth on watching its picture taken from the robotic probe at about 7-8 billion miles away,from the edge of solar system the earth appeared to be a dust particle):
That is one of the culminating points of this book, and Sagan builds up to it by describing the chronology of our increased understanding of the 9 planets that comprise our solar system (...more
The first chapter contemplated the arrogance and self-centred nature of humans, and presented the notion that humans are exceedingly small compared to the vast Universe. For the first time I really comprehended how tiny our species are. It is quite an obvious concept that gets lost in everyday worries, fears and troubles. N...more
Look again at that dot. That's here. That's home. Tha...more
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...more
Reading this took me back to my childhood and the wonder I felt when I thought about the natural world (universe) and how incredible it is. It also reminded me that science can be fun, regardless of how dull most schooling makes it. A wonderful book, and I would highly recommend it to EVERYONE.
The first half of the book is primarily about the insignificance of the human race, and how inconsequential our existence is in relation to the vastness of the universe. This may sound depressi...more
This book will make you want to explore our universe more than you ever have before, and it will make you more than slightly furious at a lot of the political decisions surrounding NASA in the nearly two decades since this book was published.
If he were still alive today, Sagan would undoubtedly be frustra...more
This book is eminently readable, though I did find myself feeling remorse for the fact that Sagan died before m...more
I don't care that he holds his beliefs, I just do not see what spending so much time on them had to do with our future of space...more
There are some interesting ideas here. I liked the way he explored looking at the earth from incredibly far away and how it would look to an entity who gradually got closer and closer and exactly how close that entity would have to get to see any evidence of intelligent life. We like to think everything we do is really impactful, but it kind of isn't -- certainly not in any meaningful w...more
I loved this book for stirring my imagination, engaging fascinations that I...more
-speculating how we might colonize asteroids
-description of the moral dilemma concerning technology that could protect the Earth from wayward space objects
-Sagan's ideas about where and how the space programs should expand in order to save money (also, group project ideas)
-similar to the above, his detailed description of the combined benefits of space ex...more
I would recommend this book to anyone with an interest in space or the future/functioning of the human race because although some of the science is above basic level, layman's terms are used so that anybody can follow. I was already aware of quite a...more
although the book has high rate , but i think it doesn't worth one star for many reasons:
1-the book has many Atheistic ideas supported by theories of the origin of life "Cosmology".
couple chapters discuss the religious ideas of the beginning of life and compare it with the scientific discoveries. it's so offensive to the one's believe. i really really don't advise to read...more
I think Carl Sagan is a must read for any person who wants to be educated. Carl was a true Renascence Man, and his best gift ( of many) was teaching us about perspective. Perspective makes us wis...more

The Earth is a very small stage in a vast cosmic arena. 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. 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.
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.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.”
