Can I give this one ten stars? If I had a religion, I would be a Carl Saganian. Love him so much.
I wonder what Carl Sagan may have thought of 9/11 and the world in the new millennium, a strife-torn place which is being shaken up and shaken out every moment. I imagine the civil but slightly horrified and slightly bemused tone he may have employed while talking about the Iraq and Afghanistan wars and the antics of the Bush administration which have become such excellent fodder for stand up comedians the world over. And I can almost detect the note of boyish enthusiasm in his voice while he ma ...more

إن تأملنا أنفسنا من منظور كوني
فإن كل واحد منا لا يقدر بثمن
إن خالفك إنساناً في الرأي ، فدعه يعيش
ففي مائة بليون مجرة لن تجد واحداً غيره

هذا باختصار هو كارل ساجان (أو سيجن) أيتها البشرية
واحد من أعظم العلماء الذين أنجبتهم هذه الأرض
ليس فقط لإسهاماته العلمية ، ولكن لإنسانيته التي تدعو حقاً للتأمل

في الحقيقة هذا الرجل يذهلني بقدرته على ربط الخيوط ببعضها وجعل العلم والفلسفة والأساطير والأدب مترابطين في مقالاته الساحرة ببهاء ورونق عجيب وخاص جدّاً

The Star system in GR is absolutely inadequate for rating this book.

Gosh, I should not use the term ‘absolutely’ for something in which everything orbits around relativity.

Anyway, I think something like this would give a better idea of my opinion about this book: my rating is an universe of zillions to the power of zillions of stars, …and expanding.

لو كنت سوف أقرأ كتاب علمياً واحداً في حياتي, بل لو كنت سوف أقراء كتاباً بشرياً واحداً, سوف أختار كتاب الكون لكارل ساغان.

عادة يكون هدف الكتب العلمية التي تكتب لغير المختصين هو تبسيط المعلومة, لكن كتاب الكون يسلك مسلكا أخر, كتاب الكون كتاب يتأمل في الكون.

I'm not sure what I could possibly say about Cosmos that hasn't already been said by countless others in the 28 years since its publication, and likely in a far more intelligent and eloquent way than I ever could. But upon recently reading this book for the first time (which may seem a bit belated, but I am, after all, only 23) it instantly became one of my favorites, a status not easily attained by any book, and so I feel compelled to say something, to expound upon its many virtues and why it h ...more
A five stars to this book.
Stars borrowed from skies that I witnessed when I was eight or maybe ten and would wake up early at pre-dawn, because that was the best time for star gazing after all.

To read Mr.Sagan, the words so simple describing the Universe so complex. To read a small passage and follow it up with a sleep filled with dreams of all those stars dying and being born every passing moment.
To recall, days of childish innocence gazing towards the infinite.Gazing in anticipation of recog

A gorgeous book in every possible way. From the lush illustration and clever diagrams clear through to Sagan's lyrical and at times whimsical narrative, this is the science book for non-scientists. (And if you are a scientist, may this be a lesson in how to tell your story.) Sagan makes the astronomy and the math and the mind-boggling complexity of the universe not only comprehensible but palatable. He wraps up our history as a species into the history of the universe (such that we can even know ...more

Let's put it simply. Cosmos is required reading for everyone who lives on this planet. It will give you a sense of perspective that nothing else can -- no lofty ideology, no omniscient religion, no inspiring quotations can explain things quite as clearly as Carl Sagan's treatise on science, reality, and the nature of things in this universe. Mind-bending and dazzling, and best of all, uncluttered by confusing scientific terminology. A book worthy of all the positive superlatives I can think of b ...more

The best book ever written.

A masterful work encompassing the whole of human existence and the universe, with a focus on science.

Sagan discusses
- evolution,
- Kepler, astrology and acceptance of truth in spite of what outcome is desired,
- Venus and Mars, including the made-up belief of life on Mars a century ago,
- the Voyager spacecrafts' Grand Tour of the Outer Planets (a rare alignment),
- ancient Greek scientists,
- Relativity,
- atoms, elements, and how star make them,
- Creation Myths, incl Hin

This book was my bible when I was an enemy of God. As a stubbornly devout atheist, this was the book I turned to for justification of my proud and arrogant rejection of my Creator. Instead of reading this pile of conjecture, I recommend reading the Holy Bible (then get on your knees and repent before the holy God who gave you life and sent His Son, Jesus Christ, to pay the penalty for your lawlessness and sin). :-)
This is one of those kind of books that comes along every few years that is so fantastic that you purposely drag out reading it in order to savor its awesomeness. It doesn't matter that it was written 25+ years ago, pre-Hubble telescope, before the fall of the USSR, etc. - Sagan's insight and wide-reaching scope are timeless.

The last few chapters are so rich in thought-provoking information they are worth re-reading. Sagan would have never wanted his work to become the foundation of a religion,
I don't get people who find this too dry, or lacking in a sense of wonder about the world. It's full of a sense of wonder, no less potent because Sagan was agnostic (not atheist, as some people say), and he expresses this almost poetically. While some of the science is falling out of date now, it's still worth reading Cosmos -- as a primer, and for Sagan's clear explanations of how the world works, and how our understanding got to this point.

I actually have the DVDs of the series as well, and wh
I went into this book hoping to learn more about the Universe, and learn more I did. The chapters that dealt with star and galaxy formations were excellent, and many times I put down the book to look up something online. I had heard about a number of these topics in passing, and it was nice to read about them with more depth. For some reason, I was entranced by the concept of the 'heliopause' (look it up: it's freaking amazing), while I was outright blown away by the fact that both Voyager satel ...more

رائع بمعنى الكلمة وتعلمت منه الكثير
I love Carl Sagan. He really does make you feel like a kid again. His excitement and enthusiasm come through clearly right from the start of this book and I'd think it would be hard for anyone not to get swept up by it. The facts and mysteries of the cosmos are fascinating especially when Carl Sagan is talking about them. There are inevitably some dry and drawn out parts,being the reason for 4 stars, but all in all fantastic.

When do we truly die ? The most logical answer would be to say that we die when the last breath escapes us and when our body and mind cease to function. But I tend to differ , death would be the loss of fascination and wonderment at the world around us. To wake up and see the sun rise everyday, to listen to birdsong in the mornings and see the blue sky above you, to feel the rain lashing at you and at times caressing you with its softness, the gentle breeze of the evenings, the feel of the sea w ...more
The span of subjects in Carl Sagan's Cosmos is wide, from the history of science to (almost) modern cosmology, from the theory of evolution to interstellar flights, from creating gods to knowing our own home - Solar System. One thing you should keep in mind: I would not recommend this book to anyone with only very basic knowledge in physics. Cosmos was first published in 1980, and science has developed enormously since. There are new theories about space that correct or completely reject some of ...more

Stunning, beautiful prose, excellent description and metaphor, incredibly accessible. Its also one of those books where you get to see the author's own genius slip into the pages accidentally, every so often. This book is the book A Brief History of Time wants to be. Problem is, ABHOT is much more boring and high concept. Sagan is and ever will be the great teacher of the masses in my opinion. This book starts out simpler than ABHOT - here on earth. It begins with what you know and slowly expand ...more

While the PBS series is dated now in its special effects, the ability of Sagan to inspire the wonderment of science and our connection with the universe is unparalleled to this day. I recommend the hardback edition, which has excellent photographs and other images.

I read somewhere that Cosmos has sold more books in foreign languages than any book other than the Bible. I hope this is true. It is a book that everyone should read, and if you can watch the series, do so! (just accept the goofy effe

I think I could categorize this book as "life-changing" for me. I think the reason I am interested in subjects such as classics and anthropology can be traced to this book! It's a very broad look at the history of the universe and the history of science, so even though it is a good 20+ years old, most of it still stands. Sagan writes in an engaging and accessible manner. This is definitely a great book for people who are interested in science, but a little afraid to approach a book about it. Sag ...more

Full disclosure here, Carl Sagan is a personal inspiration for me. A person who has affected my philosophy and thinking ever since I first heard of him, watch his television documentaries, and then took the time to read his writing. The day he died, I felt a huge sense of loss, not for myself, but the world. This man was not only brilliant, a genius of the order that you see only once a generation, but he had the soul and sensitivity that defines the best of humanity. Overstating? I don't think ...more

My earliest recollections of this book are a mix of the blurred stars of the book jacket, the original airing of the PBS series, and its connection to my father. Considering I was only 3 years old at the time, this strikes me as an indication of its import. What I remember distinctly are sitting beside the couch and watching with my father as a long DNA strand stretched out across the television screen and images of the hardbound book in my father's personal library.

“Cosmos is a Greek word for the order of the universe. It is, in a way, the opposite of Chaos. It implies the deep interconnectedness of all things. It conveys awe for the intricate and subtle way in which the universe is put together.”

“The Cosmos is all that is or was or ever will be. Our feeblest contemplations of the Cosmos stir us -- there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the gre

"Космос" е написана през далечната 1980 г., десет години преди космическият телескоп "Хъбъл" да бъде изведен в околоземна орбита, когато СССР все още фигурира на световните карти, а човечеството все по-смело отправя поглед към звездите.

За да е актуална една научна книга в толкова бързоразвиваща се област, тя трябва да съдържа много повече от стандартното количество информация и преразказ на знаковите събития. Тя трябва да хвърли светлина върху онези страни на науката, които я правят привлекателн
This review comes from a non scientific mind even though I'm studying engineering which is more keen on contemplating & extrapolating the philosophical aspects of our curious instincts.

As I read this book I kept brooding about why in the creation of our world was their a need to put those flickering bright spots in the sky. Trees exist to provide us O2, we exist to provide them CO2. Everything in nature has a purpose. Everything is balanced. What's their purpose? To keep us busy, to keep us
Carl Sagan's boyish enthusiasm fills this book ranging widely on scientific topics while emphasizing his life-long passion for communication with other intelligence in the universe.

Like Issac Asimov, Sagan is captivated by the wonder of our physical world and eager to explain it to the general public, though Sagan ventures more into speculation while Asimov is more detail oriented - not only wanting you to know about the atom, but about the parts and the forces involved, never departing from the

I cannot begin to describe how amazing this book is. Of all the books I have read in my life till now, I will always remember Carl Sagan's Cosmos as the book that brought back meaning into my life.

With wonderful humility, Dr. Sagan makes the unfathomably huge Cosmos come to life. His words, clearly written from the heart are complemented by beautiful photographs and illustrations. I cannot imagine any reader being unmoved by what Dr. Sagan is telling us.
