    Carl Sagan writes about many topics in this book, but manages to make them all readable and understandable. My favorites are his essays on exponential growth and decay, the universe, and abortion. He really clearly lays out his thoughts and makes hard to understand concepts reachable in science and mathematics. He makes what is probably the most logical argument I have ever read in the abortion debates about our need to decide what makes us human and determine at what point that happens. His short explanation of the history of abortion was enlightening (no, it never used to be a religious issue until recently). His arguments about the need to address global warming and the need to decrease nuclear arms are as timely now as they were 15 years ago. I am sad that our world has lost such a knowledgeable and persuasive man, but I am glad to know he has inspired so many others to follow in his footsteps. The world needs more intellectuals that don't blindly side with party lines, but look at facts and evidence. We need more people to stand up and honestly educate people about what is happening in our world.

    Posljednja knjiga koju je Sagan napisao prije svoje prerane smrti. U ovom djelu veliki humanist iznosi svoje viđenje nekoliko svjetskih problema, kao i svoju viziju poterncijalnih rješenja. Ražalostolo me zapravo, što se u dva desetljeća otkad je djelo napisano toliko malo pomaklo na bolje. strah, paranoja, iracionalnost, fanaticizam i zatvaranje očiju pred dugotrajnim rješenjima radi kratkotrajne koristi vladaju svijetom više nego ikada. Ima li nade za nas?

    I liken Carl Sagan's explanation of physics, mathematics and astronomy in Billions and Billions and all his books to what Steven Pinker did for the field of linguistics in The Language Instinct: he takes extraordinarily complex phenomena and breaks them down so the intelligent reader fascinated by such quandaries, but who just didn't have the passion to study them academically, can understand and muse upon. I used Pinker's work when teaching linguistics in graduate school, and I could see physics and astronomy faculty using Sagan for the same reason: to bring an inspiring and brilliant introduction to life's largest questions to curious minds. Billions and Billions is for the intelligent person fascinated by space -- on this planet, in this solar system, in this galaxy and beyond. Sagan's explanations, comparisons, analogies, and opinions (personal opinion is something that I've noted is left out in his other works) brought me to tears on more than one occasion. Life is incredibly precious, and we're so insignificant in the scheme of things, and it baffles me that many disregard, or at least have no natural curiosity for, this precious, almost improbable gift of life. Sagan forces me to contemplate human problems of politics, overpopulation, starvation, disease, climate change and pollution on not merely a global, but also universal level by using numbers and logic, elements often attributed to objectivity -- impassivity, even -- that actually are keys that unlock emotion and make us able to truly understand the human plight. Billions and Billions is a beautiful, delightful, aching and depressing, but magnificent and inspiring read. It is my hope that many people pick up Carl Sagan's works -- this is his last work, created in 1996 (he died of cancer in 1997), and I, along with many critics, believe this might be why he brings such a meaningful and personal perspective into his finale. I also hope that if you do have a natural curiosity for physics, quantum physics and mechanics, that you also look into Gary Zukav's Dancing Wu Li Masters and Fritjof Capra's The Tao of Physics. Physics is not some stale, nerdy numbers game -- it's a an intricate, meaningful, emotional, colorful dance!

    The core premise of Sagan's final book is, to paraphrase an old Native American saying, "We have not inherited the Earth from our ancestors, but have borrowed it from our children." So stop the F screwing it up.Presented as 3 parts of 19 essays in total, some of the essays, especially in the first part, are similar to the material he covered in Cosmos: cosmology and the vastness of space, our history as a species, general physics, life outside Earth. Some of the other essays are about then emerging discoveries of our effect on nature such as global warming, the ozone depletion, deforestation, and fossil fuels. Sagan does what he does best in these pieces: explain in the common tongue how the entire setup is set up, what are the various set pieces in it and their roles, and how what we're doing is causing whatever it is that's happening. Though these essays were written in the 80's and 90's and so might come across as a bit dated, they do cause some serious introspection and a poignant reminder on how much we have actually NOT progressed in dealing with and controlling them.There is an absolutely brilliant essay on the abortion debate between pro-choice and pro-life, which I think covers almost all points on either side while also clinically arriving at a practical and workable answer. A few of the essays do end up being dated, where he exhorts the need to end the cold war between the Soviet and USA, and urges everyone to stop the madness that was the nuclear race. The final essay, "In the Valley of the Shadow," where he recounts his battles over the disease that eventually killed him, is so simple and beautifully written that it is both positive and haunting.Throughout the book, though, as always with Sagan, what does come across is his child-like love and wonder for science and nature, and his enthusiasm in talking about what he loves.In the last words of Sagan himself, I would love to believe that when I die I will live again, that some thinking, feeling, remembering part of me will continue. But as much as I want to believe that, and despite the ancient and worldwide cultural traditions that assert an afterlife, I know of nothing to suggest that it is more than wishful thinking. I want to grow really old with my wife, Annie, whom I dearly love. I want to see my younger children grow up and to play a role in their character and intellectual development. I want to meet still unconceived grandchildren. There are scientific problems whose outcomes I long to witness—such as the exploration of many of the worlds in our Solar System and the search for life elsewhere. I want to learn how major trends in human history, both hopeful and worrisome, work themselves out: the dangers and promise of our technology, say; the emancipation of women; the growing political, economic, and technological ascendancy of China; interstellar flight. If there were life after death, I might, no matter when I die, satisfy most of these deep curiosities and longings. But if death is nothing more than an endless dreamless sleep, this is a forlorn hope. Maybe this perspective has given me a little extra motivation to stay alive. The world is so exquisite, with so much love and moral depth, that there is no reason to deceive ourselves with pretty stories for which there's little good evidence. Far better, it seems to me, in our vulnerability, is to look Death in the eye and to be grateful every day for the brief but magnificent opportunity that life provides.

    I am a great fan of Carl Sagan and it is with some sadness that I can recommend this, his last book, only partially. It is a collection of nineteen essays, organized into three mostly unrelated parts. Some items are well worth reading—particularly the last—but some not at all.Part 1, "The Power and Beauty of Quantification," is merely a simple echo of his famous book Cosmos: A Personal Voyage (1980). The first chapter on large numbers, from which the "Billions and Billions" of this book's title is taken, is just too basic. Experienced popular science readers should skip this part entirely. Those interested in cosmology, the vastness of space, and the possibility of multiple universes should look instead to Sagan's own classic Cosmos or for the up-to-the minute (and deep) account, see Max Tegmark's Our Mathematical Universe (2014).Part 2, "What Are Conservatives Conserving," is a series of dated essays covering the relatively new (at the time Sagan was engaged with them in the 1980s and early 1990s) environmental concerns of ozone depletion and global warming. Their outdatedness stems not from any later final solutions, but rather because research has progressed substantially in the last few decades. Another problem is that he links these essays politically to the Carter and Reagan eras, which realistically are too distant for most younger readers. Instead, for an insider's view on global warming politics read Al Gore's An Inconvenient Truth: The Planetary Emergency of Global Warming and What We Can Do About It (2006). For the science, which despite its over-the-top title is definitive, refer to James Hansen's work from 2009 Storms of My Grandchildren: The Truth About The Climate Catastrophe And Our Last Chance To Save Humanity. (Hansen is the NASA climate researcher credited for "discovering" global warming.)Happily, in Part 3, "Where Hearts and Minds Collide," Sagan includes more timeless essays covering the politics of abortion, basic morality, a powerful address at the Gettysburg peace memorial rededication, and a useful look back at the accomplishments of the twentieth century. These display Sagan at his best, and are reminiscent of the sustained intellectual wonder that is his best book The Demon-Haunted World: Science as a Candle in the Dark (1995).Sagan closes with one of the most affecting short essays I have ever read, "In the Valley of the Shadow," where he recounts his battles over the disease that killed him after he finished Billions and Billions but before it was published. He displays ferocious optimism in his own future, and also for humanity. If nothing else, read this eight-page essay at your local bookstore or online. It will move you as it has countless readers and reviewers.With great respect, and with an irresistible fantasy, and indeed hope, that he is now in some way out there among the stars, merged with his beloved cosmos, I leave the last word to Carl:I would love to believe that when I die I will live again, that some thinking, feeling, remembering part of me will continue. But as much as I want to believe that, and despite the ancient and worldwide cultural traditions that assert an afterlife, I know of nothing to suggest that it is more than wishful thinking....The world is so exquisite, with so much love and moral depth, that there is no reason to deceive ourselves with pretty stories for which there is little good evidence. Far better, it seems to me, in our vulnerability, is to look Death in the eye and to be grateful every day for the brief but magnificent opportunity that life provides.

    Sagan is eloquent as always. It helps even more to read it out loud to yourself, (muttering lest someone observe) and make up a Sagan accent as you go. He takes a gentle hand, which I think bespeaks desperation in his last years, his last chance to nudge the ball forward amidst tangible fear that forceful will be deemed strident, erudite will sound preachy, and warning the bitter rantings of an old Cassandra. Carl knows he's on the losing team, he loves humanity, and deeply fears our suicide by institutional stupidity, the tragedy of the commons, and Tainter's unwindable commitment to technological complexity beyond the point of diminishing returns.Stale stuff, understood by all in my echo chamber, thus barely worth repeating, maybe. But still, he is gone now, the gentle Lorax of our times, replaced by a stronger, similarly poetic champion (Neil) who has taken up the lance, but the windmill doesn't look worried. I am. I am in arguments I can't win. I lose faith. Like Carl, I fear I cannot push on the rudder enough to effect any change in course. Do you know the thing about Cassandra? ...about all her whining doom-laden prognoses?She was right. That's the punch line. Sagan used that and the similar story of Croesus (rich as...) who asked the Oracle at Delphi what would happen if he invaded Persia. He got back the answer: "you will destroy a great empire." He did, but it was his own empire that got destroyed. As leaders with an agenda are wont to do, he listened carefully with an ear tuned to hear what he wanted, and he heard it. That's you, Mr. Cruz, unless you subscribe to the yet more devlish code of knowing the truth and nevertheless perverting it to your will. For your sake I hope you're just stupid, not flatly evil.I'm afraid I don't think you're stupid.

    This is I think Carl Sagan's last published book, published in 1996. His chapter/essay, entitled "The Twentieth Century," is one of the most insightful summaries of what the universe is that I ever read. Well, maybe not the most insightful, but surely in the top three:"Perhaps the most wrenching by-product of the scientific revolution has been to render untenable many of our most cherished and most comforting beliefs. The tidy anthropocentric proscenium of our ancestors has been replaced by a cold, immense, indifferent Universe in which humans are relegated to obscurity. But I see the mergence in our consciousness of a Universe of a magnificence, and an intricate, elegant order far beyond anything our ancestors imagined. And if much about the Universe can be understood in terms of a few simple laws of Nature, those wishing to believe in God can certainly ascribe those beautiful laws to a Reason underpinning all of Nature. My own view is that it is far better to understand the Universe as it really is than to pretend to a Universe as we might wish it be."Just think if this were the type of book students actually studied in school and their parents studied in churches? Nuf said. #end

    Six times now have I looked Death in the face. And six times Death has averted his gaze and let me pass. Eventually, of course, Death will claim me - as he does each of us. It's only a question of when. And how.I've learned much from our confrontations - especially about the beauty and sweet poignancy of life, about the preciousness of friends and family, and about the transforming power of love. In fact, almost dying is such a positive, character-building experience that I'd recommend it to everybody - except, of course, for the irreducible and essential element of risk.The world is so exquisite , with so much love and moral depth, that there is no reason to deceive ourselves with pretty stories for which there's little good evidence. Far better, it seems to me, in our vulnerability, is to look Death in the eye and to be grateful every day for the brief but magnificent opportunity that life provides.

    I will never tire of reading Carl Sagan's thoughts on anything and everything.We’ve been here for only about a million years, we, the first species that has devised means for its self-destruction. We are rare and precious because we are alive, because we can think as well as we can. We are privileged to influence and perhaps control our future. I believe we have an obligation to fight for life on Earth—not just for ourselves, but for all those, humans and others, who came before us, and to whom we are beholden, and for all those who, if we are wise enough, will come after. There is no cause more urgent, no dedication more fitting than to protect the future of our species. Nearly all our problems are made by humans and can be solved by humans. No social convention, no political system, no economic hypothesis, no religious dogma is more important.

    Sagan can be a little repetitive but that doesn't mean his words carry no less value. The chapter on abortion is worth your time if you've ever been even mildly divided on the issue, which you should be. Also, I teared up on the bus reading In The Valley of the Shadow, which documents Sagan's fatal battle with myelodysplastic syndrome.

    What a great book. It was well written and really touched on a variety of different topics. Though it is dated now, I still feel that I gained a lot by reading it. And the last two chapters where he talked about his disease and views on death really struck deep with me.

    Written at the end of his life and published with an post script illuminating his unsuccessful battle with myelodysplasia, as well as a touching epilogue by his widow Ann Druyan. The book starts out with a kind of fleshing-out of humanity by its numbers, things like human population and resource usage and the age of the species are all implicitly synthesized into a description of people by very large numbers. It then touches on social and environmental issues, how people react to them, and what kind of things we do right and wrong when faced with science versus our comfortable beliefs about the planet. There's an essay in which Sagan and Druyan lay out a compromise position on abortion which is based in science and objective facts that neither polar side of the debate should reject. Talk is made about the possibility of a catastrophe from space, and what it'd mean for life on Earth. He writes about the richness of human experience through art, religion, and especially science. The costs and causes of war are explored. There's the almost obligatory devotion to one of Sagan's favorite subjects, the possibility of extraterrestrial life. The impression one gets throughout the whole book, no matter the subject of the text or the personal opinion of the reader, is the totally infectious nature of Sagan's awe and curiosity about the world in which we live, and even more about the Universe in which the world turns. His talent for phrasing can take something you thought was mundane and spin it into a profound insight, stirring the mind to make old ideas brand new, or crystallize into everyday life something mentioned in passing during highschool physics. With Carl Sagan's pen guiding the reader, fascination is nearly guaranteed.

    بلايين و بلايين كتاب غير عادي، ربما لان كاتبه غير عادي. يأخذك الكتاب في البداية برحلة خفيفة يطلعك خلالها على بعض العلوم و النظريات التي توصل إليها الذكاء البشري عبر الزمن و أيضاً يمر مرور سريع على التقنيات و التطبيقات لهذه العلوم و النظريات. و بما أن الكاتب هو "كارل سيغان" فمن الطبيعي أن تجد كثير من المعلومات عن الفضاء و الفيزياء و عن جمال الكون و عظمته لكن كل هذا موجود في القسم الأول فقط. و لان "كارل سيغان" يمثل العالم (بكسر اللام) المثالي لكثير من العلماء و الهواة الذين يؤمنون بالعلم، فهو لا بد أن يتحدث عن الاستخدام السيء و الجيد للعلوم و التقنيات التي ابتكرها الانسان و خصوصا في القرن العشرين، حيث يبدء في القسم الثاني بالتحدث عن الإستخدم السيء لهذه العلوم و المشاكل التي تواجه البشرية بسببها كإرتفاع درجة حرارة الكوكب و ظهور الثقب في طبقة الاوزون و إستخدم الأسلحة النووية و غيرها من المخاطر التي قد تكون مدمرة لكوكبنا. و كل ذلك كتب بلغة "كارل سيغان" البسيطة. القسم الثالث يتكلم فيه عن العدو المشترك لكل البشرية و عن المجالات التي يجب أن تتعاون بها الجميع لمواجهة الأخطار و عن أن العداوة بين دولتين أو أكثر ليست سوى وهم مؤقت حيث يجب الانتباه إلى العدو المشترك الحقيقي الذي قد يؤدي إلى تدمير الحضارة البشرية نهائيا و قد يؤدي إلى إفناء الجنس البشري بشكل كامل.ضمن الأقسام جميعها تجد "كارل سيغان" يتكلم عن الجوع و الظلم و الأمراض و الأخطار المهددة للبشرية، و تجد أيضا بين السطور ارائه عن الموت و الحياة و ما تعني له، بالاضافة للجزء الأخير من القسم الأخير من الكتاب الذي يتكلم فيه عن تجربته مع المرض و الأمل حتى وفاته حيث تختتم زوجته "أن درويان" الكتاب بكتابة الخاتمة. إنه كتاب رائع...

    Thought provoking. And honestly? More than a little disheartening. A big chunk of this book deals with the CFC disaster of the 80's-90's and the parallels to be drawn between that and current climate change...going from the analysis of the threat, to the denial by big business, to the penalties coming to fruition, before FINALLY, some change being made. It was....honestly a little depressing. And I'm not sure that's a situation that'll get better anytime soon. Recommended for food for thought.

    I must say, I have never completed a book faster:just three sittings and last half in a two hour flight to Mumbai.I am inclined to be a little proud of this achievement.My heroics were partly possible because the book is predictable in its first half, where Carl Sagan begins by enumerating the environmental problems,the world is facing,beamed especially with Ozone depletion and Global warming. The research and subsequent efforts by different companies, countries and communities have been captured well.The end is heart wrenching when it reads that Carl was writing the last chapter from his hospital bed in Hutch, Seattle. The book is definitely not even close to Cosmos or The Dragons of Eden in a strict literary sense.It contains broken linkages to chapters and sometime overstated facts but on the brighter side,we get to see Carls's inner family life and his brave battle with Myelodysplasia. His literary powers may seem to be on a decline, but his passion and conviction to spread awareness for a cause in undiminished and far from satiation.I would still recommend this book for it contains final thoughts, efforts and emotions of Carl Sagan, a great thinker, explorer and astronomer. He definitely lives on!

    Billions and Billions, which was the last book of the one and only, Carl Sagan includes 19 different essays on subjects like history of the cosmos, science and mankind, danger of nuclear weapons, ozone layer disappearing, relationship between science and religions, abortion, and especially his personal fight with the disease that took his life away from yhis world. I love the way he reasoned his arguments with simple explanation and eye-opening examples. His enthusiasm makes readers interest and follow what he tried to show with logics and facts. Carl Sagan is lost forever, but his legacies survive within many scientists and other professionals who were inspired by him. Thank you, Carl Sagan.

    Carl Sagan en sevdiğim bilim insanıdır. Onun gökbilim için yaptıkları, insanın geleceği için kaygıları, evrenin gizemini çözmek için yanıp tutuşan kalbi beni her zaman derinden etkilemiştir. Daha önce Karanlık Bir Dünyada Bilimin Mum Işığı kitabını okuduğum için bu kitabı onunla kıyaslıyorum haliyle. Karanlık Bir Dünyada... bu kitaba göre daha derli toplu ve daha tematikti. Bu kitap ise daha dağınık ve takip etmesi dolayısıyla daha zor bir derleme. En fazla kürtajla ilgili olan makaleyi sevdiğimi söyleyebilirim. Ancak Sagan, yine bir bilim insanının olması gerektiği gibi tarafsızlığı elden bırakmadan, elindeki durumu verilere dayanarak ve çok yönlü düşünerek yansıtıyor tüm makalelerde.

    Some of the essays were wonderful, some I really didn't enjoy. The book was also not what I was expecting. The last few chapters and epilogue, describing his illness and his death left me ugly crying in front of strangers on a train. Regardless of my like or dislike for this particular book, Sagan was a wonderful human, and the world is absolutely better off for having had him in it.

    No meio de todas as coisas que eu leio, confesso que não são muitos os livros que me impressionam e me fazem refletir para muito além do momento da leitura. E não são muitos os livros que me ensinam enquanto me fazem rir. E, devo dizer, é menor ainda a quantidade de livros que fazem com que eu queira ser uma pessoa melhor (para mim mesma, para os outros, para os outros seres vivos, para o planeta, para o mundo). Todos os livros que eu li do Sagan (este, Contato e O mundo assombrado pelos demônios) me deixaram com essa mesma sensação de maravilhamento. Este talvez seja, dos 3, o livro de que menos gostei dele (até porque muitas das informações científicas acabam por ficar desatualizadas), mas ainda assim é uma delícia de livro.

    Sagan's "compete with one another in good works" graf: "Let us vie in art and science, in music and literature, in technological innovation. Let us have an honesty race. Let us compete in relieving suffering and ignorance and disease; in respecting national independence worldwide; in formulating and implementing an ethic for responsible stewardship of the planet."

    the final two chapters - “In The Valley of the Shadow” and Ann Druyan’s epilogue - are potentially the most heartbreaking, thoughtful, fiercely loving things i have ever read. a worthy legacy for a most great, kind, and brilliant mind.

    “The hard-liners on each side encourage one another. They owe their credibility and their power to one another. They need one another. They are locked in a deadly embrace.”Dr. Carl Sagan wrote this in a piece dual-published by prominent magazines in the United States and the then Soviet Union. But it could just as easily describe the current toxicity of American politics, any given regional feud, or even big-box stores competing for sales on a day purportedly dedicated to thanksgiving. The above quote is just one of dozens I underlined, starred, or wrote notes next to in my now beloved copy of Billions and Billions.As with similar books I’ve read by Dr. Sagan, or other scientists like Neil deGrasse Tyson, this is more a collection than a single work. It is at once marvelous and troubling to see how relevant this book remains, published in 1997 in the wake of Carl’s death, and including material written during the final stages of the Cold War. Trends come and go. Wisdom proves itself with a longer shelf life. For devotees of Sagan, this book is a must read. It includes highly personal reflections about the illness that was beginning to take his life. Especially in Part III, “Where Hearts and Minds Collide”, it contains some of his most impassioned and courageous statements. I admire the way he takes everyone to task, including scientists. Within the scientific discourse, transcending the facts and figures, can be found Sagan’s deep love for our species, and his abiding hope that we can grow up, can survive, and can improve. A great deal of the material is highly inspirational, but mingled with some healthy scolding of our favored institutions and ourselves. I maintain that the best place to begin an exploration of Carl Sagan’s work is through his TV series Cosmos. However, Billions and Billions is not to be missed. It contains many treasures for the thoughtful reader.

    عن سفونية ساجان العلمية و كرأي شخصي إنَّ كان لديه مقدرة رائعة علي سرد مواضيع شتاه و بطريقة محنكة و منشابكة بطريقة مربكة -الباب الاول من تذوقه لجمال الترقيم الأسي و الي البادئة و إشباع غريزة الصيد بالأنشطة الرياضية و رقعة الشطرنج الفارسية و علاقتها بالتزايد الهندسي و منه الي الذبذبات و الموجات و الضوء و هل هو " جسيم ام موجة؟" و الفصل الخامس الذي شخصيا أفضله لختصاصه بالفيزياء الفلكية و الأسئلة الأربعة الكونية *رايكم حول احد الأسئلة الكونية * - الباب الثاني و بداً من كرة البلورإلي القشريات و تأثيرها علينا في سلسة الغذايئة الحيوية.و من ابولو و الأساطير الإغريقية الي أنكر الخطر الذي يواجه كوكبنا. و ما يتبعه الي تعديد لمسببات الضرر البيئي من فلوركلوروكربون و ثقبه للأُوزون الوقود الاخفوري و ما أدرك ما الوقود الاحفوري الكاربون دو اوكسايد "co2" و الاحترار العالميو ما يليه من تجاهل سياسي صناعي لهذه الأخطار. و نتابتني شيٌء من الدهشة عندما تطرق ساجان إلي دور الأديان علي رغم من كونه "ملحد" و القدرة الديانات علي ان تكون وسيط لكبح جماح العلم و العلماء الذي ينتمي اليها- الباب الثالث و وقفه في المقال علي خط الحياد و توجيه الإنتقتادات الاذعة في حق بلده الأم و ثاني أكبر الدول من حيث القوة العسكرية و أكثرها تعسفا لحق النقد الصحفي و يالا روعة هذا الشيء ! .و من بعدُ الي الإجهاض بين الأنانية و الإيثار و المنطقية و الواقعية و ما إلي ذلك من أرآء للحكومات و بالأخص الأمريكية في هذا الشأن طوال القرن المنصرم. ثم محطة قواعد اللعبة و السياسات الخارجة و تضاربها مع السياسات السرية الداخلية لدول و الي منظور اقل اي في حياة الفرد. جتسبرج و وصولاً للأسلحة النووية الحرارية و جدال في كونه حق وطني قومي في الدفاع عن سيادة الدول لذاتها الي داوافع الخفية لسيطرة علي العالم. الي تطور العلمي المهول مقارناً الحال الذي كان عليه العالم بداية القرن 20 إلي نهايته .و أخيرا أعتقد ان الكتاب يحمل رسالة إنسانية ضمن طياته سواء كان ذلك من الناحية العلمية و الشخصية كما حدث ذلك في نهاية الكتاب حيث أراد ساجان ان يتجرد من كونه عالم الفلك ليتحدث عن معاناته الشخصية الانسانية مع المرض الذي أصابه
