    About "Carl Sagan"

      • Carl Sagan

        In 1934, scientist Carl Sagan was born in Brooklyn, N.Y After earning bachelor and master s degrees at Cornell, Sagan earned a double doctorate at the University of Chicago in 1960 He became professor of astronomy and space science and director of the Laboratory for Planetary Studies at Cornell University, and co founder of the Planetary Society A great popularizer of science, Sagan produced the PBS series, Cosmos, which was Emmy and Peabody award winning, and was watched by 500 million people in 60 countries A book of the same title came out in 1980, and was on The New York Times bestseller list for 7 weeks Sagan was author, co author or editor of 20 books, including The Dragons of Eden 1977 , which won a Pulitzer, Pale Blue Dot 1995 and The Demon Haunted World Science As a Candle in the Dark 1996 , his hardest hitting on religion With his wife, Ann Druyan, he was co producer of the popular motion picture, Contact, which featured a feminist, atheist protagonist played by Jodie Foster 1997 The film came out after Sagan s death, following a 2 year struggle with a bone marrow disease Sagan played a leading role in NASA s Mariner, Viking, Voyager, and Galileo expeditions to other planets Ann Druyan, in the epilogue to Sagan s last book, Billions and Billions Thoughts on Life and Death at the Brink of the Millennium published posthumously in 1997 , gives a moving account of Carl s last days Contrary to the fantasies of the fundamentalists, there was no deathbed conversion, no last minute refuge taken in a comforting vision of a heaven or an afterlife For Carl, what mattered most was what was true, not merely what would make us feel better Even at this moment when anyone would be forgiven for turning away from the reality of our situation, Carl was unflinching As we looked deeply into each other s eyes, it was with a shared conviction that our wondrous life together was ending forever For his work, Dr Sagan received the NASA medals for Exceptional Scientific Achievement and twice for Distinguished Public Service, as well as the NASA Apollo Achievement Award Asteroid 2709 Sagan is named after him He was also awarded the John F Kennedy Astronautics Award of the American Astronautical Society, the Explorers Club 75th Anniversary Award, the Konstantin Tsiolkovsky Medal of the Soviet Cosmonauts Federation, and the Masursky Award of the American Astronomical Society, for his extraordinary contributions to the development of planetary science As a scientist trained in both astronomy and biology, Dr Sagan has made seminal contributions to the study of planetary atmospheres, planetary surfaces, the history of the Earth, and exobiology Many of the most productive planetary scientists working today are his present and former students and associates.He was also a recipient of the Public Welfare Medal, the highest award of the National Academy of Sciences.Dr Sagan was elected Chairman of the Division of Planetary Sciences of the American Astronomical Society, President of the Planetology Section of the American Geophysical Union, and Chairman of the Astronomy Section of the American Association for the Advancement of Science For twelve years he was the editor in chief of Icarus, the leading professional journal devoted to planetary research He was cofounder and President of the Planetary Society, a 100,000 member organization that is the largest space interest group in the world and Distinguished Visiting Scientist, Jet Propulsion Laboratory, California Institute of Technology.In their posthumous award to Dr Sagan of their highest honor, the National Science Foundation declared that his research transformed planetary science his gifts to mankind were infinite D 1996.More ffrf news day dayitems it

    2. لو غاوى كتب الأرصفه و الأعلى مبيعا سيعجبك ككتاب خفيف و ممتع و اسلوبه شيق لكن لو بتقرأه من أجل الماده العلميه هتلاقيه سطحى و غير دقيق و يستند لأطروحات و استنتاجات نظرية لم يدعمها العلم بصوره قاطعه و لا حتى بصورة شبه مؤكدة.العنوان خادع شويتين و لو انه متوقع ان كتاب بالحجم الصغير [...]

    3. "كتنانين عدن""إننا نتهم الأرواح الشريرة بأنها السبب في الصرع ؛ لأننا لا نفهم له سبباً آخر, ولو أننا اتهمنا الأرواح الشريرة بكل مرض لا نعرف له سبباً لامتلأ الكون بهذه الأرواح" أبوقراطفي عام 1975, قام المؤلف "كارل ساجان" بتقديم أول محاضرة لذكرى "جايكوب برونسكي" في "الفلسفات الطبيعي [...]

    4. The most hauting question that this book poses is this : Chimpanzees can abstract. Like other mammals, they are capable of strong emotions.Why, exactly, all over the civilized world, in virtually every major city, are apes in prison? For a species that has proclaimed itself to be the rulers of Earth, this is not a very difficult question to answer for us. It is a single word : suppression. We humans never much liked competition from other creatures and history tells us that this was how we overc [...]

    5. One of the most beautiful things I've ever read came from this book:"If the human brain had only one synapse-- corresponding to a monumental stupidity-- we would be capable of only two mental states. If we had two synapses, then 2^2 = 4 states; three synapses, then 2^3 = 8 states, and, in general, for N synapses, 2^N states. But the human brain is characterized by some 10^13 synapses. Thus the number of different states of a human brain is 2 raised to this power-- i.e multiplied by itself ten tr [...]

    6. I'd read this book a few years ago, and loved it. It's a great introduction to brain anatomy, consciousness/subconsciousness, and evolution. An "easy" read, if any book that deals with these types of topics can be considered as such. Sagan is good at presenting complex material in an interesting and palatable way. It made me want to start paying more attention to my dreams. (He also relates one of his personal experiences of smoking marijuana, and his theories of the effects it might have on the [...]

    7. "Chimpanzees can abstract. Like other mammals, they are capable of strong emotions.Why, exactly, all over the civilized world, in virtually every major city, are apes in prison?""Humans have systematically exterminated those other primates who displayed signs of intelligence."Carl Sagan is the best science teacher one can ever get. Even though I am not a biology major, I was able to enjoy this book. A great book where he talks about EVERYTHING that you ever wanted to know about your brain. Proba [...]

    8. Interesting read, as long as one takes into account that it's quite old and outdated by now, so it's not exactly cutting edge. (I read it pretty long ago myself).Still, Sagan has a such a pleasant, conversational style, that even reading it for the speculations alone, makes reading the book a not unpleasant way of whiling away your time.I like the angles he chooses to speculate from, especially the bits about instinct and how myths most probably formed in the human collective subconscious.

    9. Interesting questions on the origin and development of human intelligence. Still worth a read despite lots of progress since he wrote this. Gives a good description of left/right brain competencies. Has piqued my interest in evolutionary development. The guy was taken from us too early but sure made a name for himself in what time he had.

    10. ¡He leído mi primer libro de Sagan! No saben cuánto tiempo llevaba esperando esto. Tantas recomendaciones, tanto cariño de tanta gente por este gran hombre siento que lo quiero por la semilla que ha dejado en tantas personas, tuvo que ser un gran hombre para marcar tanto a toda una generación. Es increíble que yo lo admirara tanto sin conocer su trabajo, solo por ver cómo la gente hablaba de él. Y por fin me atreví, mi primer libro de Sagan. Vamos con él.No, no es un libro sobre astron [...]

    11. Bugün öğlen saatlerinde büyük bir heyecanla elime aldığım kitabı an itibariyle üzülerek bitirmiş bulunuyorum. Cosmos kitabıyla tanıştığım Sagan'ın biraz daha farklı konulara değindiği bu kitabını da Cosmos ile aynı keyif ve heyecanla okudum. Sagan'ın ne kadar büyük bir deha olduğunu bir defa daha gördüm. Zira, alanı dışında bir konuda yazıyor ve bunda da son derece başarılı olduğunu düşünüyorum. Her ne kadar, bilimin doğal akışı gereği kitaptaki b [...]

    12. This was an interesting book to read after all of the recent research and groundbreaking discoveries of the human brain. Clearly, Sagan smokes weed. However, there are times when he must be coming off his high that his insights are both subtle and poignant. Oxymoronic, to be sure, but so was most of Sagan's keen skepticism amidst his psuedoscientific platitudes.I use big words. That being said, some of the best parts of this book are the drawings related to studies conducted on patients with a s [...]

    13. Carl Sagan, like Stephen Jay Gould, is one of those scientists gifted as a teacher to non-specialists. This book is about intelligence, a topic both men dealt with, Gould most notably in his Mismeasure of Man. Sagan, however, deals with all intelligence, ending his book with a discussion of nonhuman intelligences, most particularly certain Cetaceans and primates. Noting that chimpanzees and gorillas appear to be intellectually comparable to human five-year-olds, he ends with a plea to extend som [...]

    14. I read this one quite long back and really loved it at that time. I only remember two things from the book, however.The first one is where Sagan speculates that God's curse on Eve, "you shall bring forth your children in pain", refers to the increased cranial size of intelligent homo sapiens. It is common knowledge that childbirth in humans is much more painful than in animals because of the larger size of the head due to an enlarged brain: thus, could the story of Eden contain a veiled referenc [...]

    15. I feel strongly that this book should be included in mythology courses because better than any textbook I've ever encountered it addresses the connections that exist between mythology and science. Not to say that mythology is scientific, but rather the ways of viewing the world, both contemporary and historical, that human beings seem to return to again and again often are the way they are for very sound biological reasons.

    16. Knjiga je jednostavno nevjerojatna. uz minimalno, ali stvarno minimalno poznavanje anatomije i fiziologije mozga-na razini osnovnoškolske biologije- čitatelj može pratiti razvoj građe i funkcije ljudskog mozga, uz savršeno smisleno i logično objašnjenje naših strahova, ponašanja, snova, uspjeha i neuspjeha. preporučeno svima.

    17. استمتعت كعادتى مع كتب الرائع الجميل كارل ساجان خاصة فى الفصل الذى ناقش به تعلم الشمبانزى للغة الاشارة واطلقت العنان لخيالى لو ان كل الشمبانزى والقردة تعلم لغة الاشارةواصبح بيننا وبينهم نوع من التواصل كيف سيكون شكل الحياة الاجتماعية بل الحياة ع الكوكب بعدما يصبح الشمبانزى ك [...]

    18. Pure bliss. In the inimitable manner of Carl Sagan, engrossing, enlightening and amusing in equal measure.

    19. Да яздиш дракони в Райската градина: knigolandiafo/book-review/dСлед мечтата за Вселената, събрана в “Бледа синя точица”, дочакахме със скромните четирийсетина години закъснение и още една от книгите на великия Карл Сейгън – “Дракони в Райската градина”. От погледа към Космоса той н [...]

    20. This is simply the best book I was lucky enough to receive as a gift. Written thirty years ago, Sagan's principles in science, philosophy, and humanity seem to grow more valid as the years go on. I used to be an existentialist nutcase in high school, but this book straightened me right out. I can't wait to re-read this beauty

    23. "To write a book in a subject so far from one's primary training is at best incautious. Bute temptation was irresistible."That quote, found in the acknowledgements, sums up both the problems with this work, and also it's ironic charm. You must read this early work of Sagan not as definitive science, but as a prime example of his inimitable ability to connect science to other intellectual concerns such as myth, religion and history, thus stimulating thought in the process.At least Sagan is comple [...]

    24. "There is a popular game, sometimes called Pong, which simulates on a television screen a perfectly elastic ball bouncing between two surfaces. Each player is given a dial that permits him to intercept the ball with a movable "racket". Points are scored if the motion of the ball is not intercepted by the racket. The game is very interesting. There is a clear learning experience involved which depends exclusively on Newton's second law for linear motion. As a result of Pong, the player can gain a [...]

    25. Carl takes you on a journey from the mountains to the oceans, from dinosaurs to extra terrestrial beings to explain evolutionary changes and the workings of our mind. While explaining these concepts in a simple, easily understandable language, he lays out the arguments and lets you figure out for yourself intriguing ideas such as how much sleep is enough; why some people can do with less sleep?; why we think the way we do; why do we have our appendages evolved in the way they are; are we continu [...]

    26. Any book on the brain written in the 70s is going to be outdated. For example, Sagan wasn't sure if different parts of the brain affected different things. But an enjoyable read. He does make one important point clear early on: the "mind" is just a function of the brain. Dualists who think they are two different things are flat out wrong. I have had people look me straight in the eye without even blinking and say that if a person's brain were destroyed, their mind would still function normally. [...]

    27. A look into the evolution of the human mind. Sagan closes the first chapter giving the reader a perspective on their position in history: If the history of the universe was represented by our 12-month year, the history of mankind would exist in the last second of the last minute of December 31. Exploring the pains of childbirth, warring subhuman species, and simplified understandings of how the human brain works, "The Dragons of Eden" is written in a way that anyone can enjoy (it was a NY Times [...]

    28. Carl Sagan was a planetary scientist with primary interest in exobiology and extraterrestrial intelligence. He was perfectly aware that speculation, study and understanding of extra-terrestrial intelligence would require a thoroughly comprehensible understanding of terrestrial human and non-human intelligence such as primates and aquatic mammals. If emergence of intelligence is convergent end point of many different evolutionary histories, as evident in our expectations of intelligent aliens, th [...]

    29. كتاب اخر جميل من ابدع ما كتب العالم الجليل كارل ساجان هو واحد من العلماء الموسوعيينهو مسئول برنامج البحث و الاتصال بالكائنات الاخرى خارج نظامنا الشمسى فى ناساتخصصه فى الاتصال بالموجات الرادوية العابرة للمجرات و مع ذلك نجده يكتب فى الطبيعة و الاحياء و البيولوجية و التطور وا [...]

    30. Un ensayo muy interesante sobre la evolución fisiológica del cerebro desde sus primeros desarrollos hasta el Homo Sapiens, con el que he aprendido cosas que seguramente ya sabía pero que quedaron enterradas en un absurdo marasmo de educación multidisciplinar que me ha llevado a saber de todo y nada a la vez, lo que me hace una persona muy interesante a la hora de conversar (siempre que te guste mucho la forma y poco el fondo). Lo más interesante me ha parecido la existencia del Complejo R, [...]
