Can I give this one ten stars? If I had a religion, I would be a Carl Saganian. Love him so much.

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

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

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

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

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

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),

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). :-)
In the beginning there was a bang, and it was big. Stupendous. The universe as we know it, began. Time itself started to tick and tock. Space was appearing seemingly out of nothingness, as it continues to do so still. Intense heat and energy were produced. And from them matter coalesced. And so stars formed. And from stars everything else sprang into existence: more stars, galaxies, the glorious milky way, our spectacular sun, our caring earth, our gorgeous moon shortly thereafter, and finally, ...more

As a child, I was fascinated and mesmerised by our world. It looked so huge, so full of wonders. Еverything was a source of marvel and inspiration. The world, the Earth, waited to be discovered and I had a long life ahead of me to do that.

Then, in teenage years, I already knew all there was to know about life, people, the Earth and the Universe. Nobody could tell me any better. The new source of wonder had become love – falling in love, finding the purpose in another human being, the complete m

The surface of the Earth is the shore of the cosmic ocean. On this shore, we've learned most of what we know. Recently, we've waded a little way out, maybe ankle-deep, and the water seems inviting.

It has always made me very curious how science touches many other seemingly different subjects of history, philosophy, and religion. This book is really very impressive. A story of 15 billion years of the cosmos compressed in this relatively smaller book! Easy to read and understand, Carl Sagan's Cosmos draws the reader into a world so vivid and realistic that it's hard not to be mesmerized throughout while reading this book.

كتاب رائع
هو مش بيتكلم عن نظريات ف الكون او قوانين فيزيائية او رياضية والحاجات دي يعني زي م انا كنت متوقعة ..
هو بيتكلم عن كل حاجه ف الكون ، بيتكلم عن نظرية داروين التطور ، عن الكواكب الثانية وطبيعتها، عن اسكندرية زمان لما كانت مركز نشر العلم ف العالم ، عن الوقت الي اكتشفوا فيه الامريكتين والتجارب الي فشلت ف اكتشافها قبل كده ، عن السفر عبر الزمان ودلل ع ده بأن الحاجة الي زمان كانت بتخلص ف شهور بقت بتخلص ف دقايق دلوقتي ..
بيتكلم عن علماء كتير وتجاربهم وحبهم للعلم من عصور قبل الميلاد لحد دلوقتي ..

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 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

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.

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.

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.

This book and series sparked my interest in science and the universe in 1980 when I was thirteen. It is not cutting edge today but the poetry and wonder of Carl Sagan's vision still is current. Reading this book 36 years after the series reminds me of how science and a vision of universe can inspire people long after the science of the book has been surpassed. Beautiful book.

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.
