Carl Sagan was a good writer. For a scientist, his prose had a literary style that is enjoyable to read, and he injected a sense of philosophy into his passionate account of the origins and marvels of the cosmos.

I do find that the delivery was quite heavy-handed in trying to instill that sense of awe and wonder into the reader. What made it even more so was the narrator whose intonation carries a quality of breathless resonance. The arrangement of the subject matter also seemed a bit haphazard Carl Sagan was a good writer. The arrangement of the subject matter also seemed a bit haphazard in my view.

I couldn't help comparing this book to a favourite of mine - A Short History of Nearly Everything by Bill Bryson which was organised, concise, informative, and very entertaining.

Regardless, Cosmos is still a good primer to read for those who are interested in learning more about the universe and our world before venturing into more recent writings from the likes of Stephen Hawkings may he rest in peace and Neil deGrasse Tyson.

Black holes, gravity waves, Higgs boson, and dark matter were mathematical theories a generation ago.

Today they are reality. Popular science television shows can teach the public about quantum theory but anything over ten years old is pretty much out of date. How can a publication on general science over thirty-five years out of date be relevant in the world today? It depends on who and how the story is told. Carl Sagan possesse Science is changing the way we see the universe at a rapid pace. Carl Sagan possessed a quality that that was very inclusive. He spoke with a sage-like wisdom and in a way that Buddhist monk would speak, but without the riddles -- Here is what I have and I wish to share it with you.

Sagan foremost was human and looked at things in a very human way. The story of science, our understanding of the cosmos, is, of course, our view as humanity.

Cosmos covers the beginning of the universe, life on earth, the rise of man, and what man has accomplished. The Library at Alexandria was an ancient high point.

Knowledge was willingly destroyed. Mankind rose and fought discovering science. Man excelled in launching Voyager space probes but failed in the nuclear build up of the Cold War which was still in full force while this book was being written. Cosmos remains as interesting relevant after thirty-five years and will likely remain relevant in another thirty-five. Cosmos remains a book about science and a book about mankind and his quest for knowledge as well the suppression of knowledge.

But, there is hope. As Sagan said: 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. Some part of our being knows this is where we came from. We long to return, and we can, because the cosmos is also within us. We're made of star stuff. We are a way for the cosmos to know itself.

Re-visit The Shores of the Cosmic Ocean: After an introduction by Ann Druyan, including the benefits of the end of the Cold War, Carl Sagan opens the program with a description of the cosmos and a "Spaceship of the Imagination" shaped like a dandelion seed.

Eratosthenes' attempt to calculate the circum Re-visit Eratosthenes' attempt to calculate the circumference of Earth leads to a description of the ancient Library of Alexandria. Finally, the "Ages of Science" are described, before pulling back to the full span of the Cosmic Calendar. One Voice in the Cosmic Fugue: Sagan discusses the story of the Heike crab and artificial selection of crabs resembling samurai warriors, as an opening into a larger discussion of evolution through natural selection and the pitfalls of the theory of intelligent design.

Among the topics are the development of life on the Cosmic Calendar and the Cambrian explosion; the function of DNA in growth; genetic replication, repairs, and mutation; the common biochemistry of terrestrial organisms; the creation of the molecules of life in the Miller-Urey experiment; and speculation on alien life such as life in Jupiter's clouds. Sagan discusses comets and asteroids as planetary impactors, giving recent examples of the Tunguska event and a lunar impact described by Canterbury monks in It moves to a description of the environment of Venus, from the previous fantastic theories of people such as Immanuel Velikovsky to the information gained by the Venera landers and its implications for Earth's greenhouse effect.

The Cosmos Update highlights the connection to global warming. Blues for a red planet: The episode, devoted to the planet Mars, begins with scientific and fictional speculation about the Red Planet during the late nineteenth and early twentieth centuries H.

It then moves to Robert Goddard's early experiments in rocket-building, inspired by reading science fiction, and the work by Mars probes, including the Viking, searching for life on Mars. The episode ends with the possibility of the terraforming and colonization of Mars and a Cosmos Update on the relevance of Mars' environment to Earth's and the possibility of a manned mission to Mars.

Traveller's Tales: The journeys of the Voyager probes is put in the context of the Netherlands in the seventeenth century, with a centuries-long tradition of sailing ship explorers, and its contemporary thinks such as Constantijn Huygens and his son Christian. Their discoveries are compared to the Voyager probes' discoveries among the Jovian and Saturn systems. In Cosmos Update, image processing reconstructs Voyager's worlds and Voyager's last portrait of the Solar System as it leaves is shown.

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 greatest of mysteries. A peak into the Cosmos. Sagan is a poet-scientist, he uses beautiful metaphors and aphorisms that are never too far from what an ordinary person can grasp.

The style is lucid. Building on the works of geniuses who introduced us to this fascinating, mind boggling universe of ours. Kepler gave us the laws of planetary motion.

Laws that not just explained the elliptical orbit of Earth, but inspired a generation of mathematicians and physicists to inquire further into the nature and behaviour of the heavenly bodies.

A world so strange, complex and inaccessible has been made fascinating, understandable and rather accessible by the works of men and women who devoted their lives to Science and Cosmos. A world that is far more rich and awe-inspiring than the meagre and myth-ridden fairytales that we content ourselves with. We settle for too little. He admits that as a child, he spent hours contemplating about the possibility of intelligent life on other planets.

Although our search for intelligent life has been a failure even on Earth , Sagan aspires to make contact with the dwellers of distant worlds. Space travel and Alien Contact are not stuff of science fiction anymore but a possibility in waiting. The concluding chapters touch on two matters of colossal significance, namely Nuclear Weapons and Climate Change. These two man-made disasters are a ticking time bomb that can obliterate our species, and we have done precious little to stop them.

We are destroying this planet, poisoning our oceans and destroying Specie after specie for centuries now. Man is without a doubt the most deadly predator in the history of Earth Life. And now we are on the path to self-annihilation. And this book is a wakeup call. A world ridden with ignorance and greed, will need to forego the idiotic bliss of being certain about everything. A good question is often times more educating than its answer. How can we love this world if we are awaiting an apocalypse, how can we love our environment and its safe keepers, the plants and the animals, without recognising that they are our distant cousins.

Life, wherever it exists on this planet, is our kin. And we are bullying, butchering and asphyxiating it everywhere. What a shame! This is the kind of book that we must read and re-read. A book we must gift our children on their 12th birthdays. Because Carl Sagan does more than just educate you about the wonders of Science and the Universe; he makes you fall in love with it.

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.

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 As a child, I was fascinated and mesmerised by our world. The new source of wonder had become love — falling in love, finding the purpose in another human being, the complete merging of body and soul. Once I entered the world of adults, I realised that I knew nothing. I strived for a higher purpose which, it turned out, was extremely hard to find in between a daily job that gives you no thrill, the same four walls you hide behind every night, and the usual faces that say the same words day in day out.

The mundanity and routine that sustain a human life make it really hard to notice this same life. And then I started to seek answers, cosmic answers. Suddenly, it feels like a meteorite has hit my little planet. I feel like a child again!

I feel in love again! I feel my senses being heightened and my pulse rushing. Carl Sagan made me feel like a scientist. For I have made a wonderful discovery - the nutrient of my little earthly life is curiosity — no step for the Cosmos, one giant leap for the cosmic speck of dust that I am.

I could talk for hours about how beautiful and captivating I found Cosmos to be. It made me crave knowledge of the unknown. It made my underdeveloped imagination burst with colourful visions.

It made my stunted mind race. I savoured every word, embraced every idea. I guess for someone who has read a lot on the subject I look like a newly hatched chicken, struggling to make its first steps.

I have been intimidated by physics and chemistry all my life and now it is time to catch up. My gut tells me that Sagan is not right in completely rejecting astrology, the occult or religion, but I choose to trust him because he has managed to put into simple words concepts that have scared away so many people for so long.

His narrative voice is the perfect combination of a bright mind and humility. It is subtle and guiding, not patronizing. It is human and it is humane — it makes you believe you can understand and dream beyond the boundaries of your own mind. Sagan was a great scientist, but I think his greatest achievement is that he made science accessible and interesting to his fellow human beings. His venture to bring the Cosmos closer to humans might eventually pay off in helping bring humans closer to the Cosmos.

I feel ashamed that my review of this monumental work revolves around my little nichtigkeit, but, after all, even the biggest galaxies are made of the smallest particles. Jan 27, Rob rated it it was amazing Recommends it for: 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 A gorgeous book in every possible way.

He wraps up our history as a species into the history of the universe such that we can even know it. As a kid, I adored this book for the color plates. I would flip the pages in my Dad's copy over and over and over again. Down on the floor, on the couch -- anywhere. Probably every day from ages four through seventeen. I didn't go on to be an astronomer. Hell, I never took a physics class and I nearly failed more than one math class as I recall but this book Reading it cover-to-cover for the first time as an adult, I was struck by many things.

The book is dense but Sagan paces it well, makes you hungry for every anecdote about Kepler or Pythagoras, thirsty for the decimal-laden scientific notation. And then there was the moment that blew my mind; tucked away in a footnote about telescopic "snapshots" of galaxies: The near side of a galaxy is tens of thousands of light-years closer to us than the far side; thus we see the front as it was tens of thousands of years before the back.

But typical events in galactic dynamics occupy tens of millions of years, so the error in thinking of an image of a galaxy as frozen in one moment of time is small. View all 5 comments.

One of the greatest books on understanding the universe and our place in it. Moving and mesmerizing. No book has been more effective in making me appreciate existence. This is the closest I have ever been to love. This book is not only a huge source of knowledge for those looking forward to getting enthralled into the science of cosmos, but also one that I know has a special meaning for some people out there.

Both of the before mentioned apply to me, but why do I say it has a special meaning? Well, as simple as it may sound, this book was what took me to where I am right now.

But 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'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. That kind of skeptical, questioning, "don't accept what authority tells you" attitude of science — is also nearly identical to the attitude of mind necessary for a functioning democracy. Science and democracy have very consonant values and approaches, and I don't think you can have one without the other.

Talk of the Nation 3 May Who is more humble? The scientist who looks at the universe with an open mind and accepts whatever it has to teach us, or somebody who says everything in this book must be considered the literal truth and never mind the fallibility of all the human beings involved? Those who raise questions about the God hypothesis and the soul hypothesis are by no means all atheists.

An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence. Because God can be relegated to remote times and places and to ultimate causes, we would have to know a great deal more about the universe than we do to be sure that no such God exists.

To be certain of the existence of God and to be certain of the nonexistence of God seem to me to be the confident extremes in a subject so riddled with doubt and uncertainty as to inspire very little confidence indeed.

Carl Sagan July , Cosmos ebook edition , Random House ; I think people in power have a vested interest to oppose critical thinking. Essay as "Mr. X" [ edit ] Essay as Mr. X and here , written in for Marihuana Reconsidered by Lester Grinspoon There is a myth about such highs: the user has an illusion of great insight, but it does not survive scrutiny in the morning.

I am convinced that this is an error, and that the devastating insights achieved when high are real insights; the main problem is putting these insights in a form acceptable to the quite different self that we are when we're down the next day.

I had become friendly with a group of people who occasionally smoked cannabis , irregularly, but with evident pleasure.

Initially I was unwilling to partake, but the apparent euphoria that cannabis produced and the fact that there was no physiological addiction to the plant eventually persuaded me to try. My initial experiences were entirely disappointing; there was no effect at all, and I began to entertain a variety of hypotheses about cannabis being a placebo which worked by expectation and hyperventilation rather than by chemistry.

After about five or six unsuccessful attempts, however, it happened. There's a part of me making, creating the perceptions which in everyday life would be bizarre; there's another part of me which is a kind of observer.

About half of the pleasure comes from the observer-part appreciating the work of the creator-part. I smile , or sometimes even laugh out loud at the pictures on the insides of my eyelids.

In this sense, I suppose cannabis is psychotomimetic, but I find none of the panic or terror that accompanies some psychoses. Possibly this is because I know it's my own trip, and that I can come down rapidly any time I want to. The cannabis experience has greatly improved my appreciation for art , a subject which I had never much appreciated before.

The understanding of the intent of the artist which I can achieve when high sometimes carries over to when I'm down.

This is one of many human frontiers which cannabis has helped me traverse. There also have been some art-related insights — I don't know whether they are true or false, but they were fun to formulate. Cannabis also enhances the enjoyment of sex — on the one hand it gives an exquisite sensitivity, but on the other hand it postpones orgasm: in part by distracting me with the profusion of image passing before my eyes.

The actual duration of orgasm seems to lengthen greatly, but this may be the usual experience of time expansion which comes with cannabis smoking. I do not consider myself a religious person in the usual sense, but there is a religious aspect to some highs. The heightened sensitivity in all areas gives me a feeling of communion with my surroundings, both animate and inanimate.

Sometimes a kind of existential perception of the absurd comes over me and I see with awful certainty the hypocrisies and posturing of myself and my fellow men. And at other times, there is a different sense of the absurd, a playful and whimsical awareness.

Both of these senses of the absurd can be communicated, and some of the most rewarding highs I've had have been in sharing talk and perceptions and humor. Cannabis brings us an awareness that we spend a lifetime being trained to overlook and forget and put out of our minds. A sense of what the world is really like can be maddening; cannabis has brought me some feelings for what it is like to be crazy, and how we use that word "crazy" to avoid thinking about things that are too painful for us.

In the Soviet Union political dissidents are routinely placed in insane asylums. The same kind of thing, a little more subtle perhaps, occurs here: "did you hear what Lenny Bruce said yesterday? He must be crazy. I can reconstruct the actual occurrences in childhood events only half understood at the time. Many but not all my cannabis trips have somewhere in them a symbolism significant to me which I won't attempt to describe here, a kind of mandala embossed on the high.

Free-associating to this mandala, both visually and as plays on words, has produced a very rich array of insights. There is a myth about such highs: the user has an illusion of great insight, but it does not survive scrutiny in the morning. Incidentally, I find that reasonably good insights can be remembered the next day, but only if some effort has been made to set them down another way.

If I write the insight down or tell it to someone, then I can remember it with no assistance the following morning; but if I merely say to myself that I must make an effort to remember, I never do. I find that most of the insights I achieve when high are into social issues, an area of creative scholarship very different from the one I am generally known for.

I can remember the night that I suddenly realized what it was like to be crazy, or nights when my feelings and perceptions were of a religious nature. I had a very accurate sense that these feelings and perceptions, written down casually, would not stand the usual critical scrutiny that is my stock in trade as a scientist.

If I find in the morning a message from myself the night before informing me that there is a world around us which we barely sense, or that we can become one with the universe, or even that certain politicians are desperately frightened men, I may tend to disbelieve; but when I'm high I know about this disbelief. And so I have a tape in which I exhort myself to take such remarks seriously. I say "Listen closely, you sonofabitch of the morning! This stuff is real! I am convinced that there are genuine and valid levels of perception available with cannabis and probably with other drugs which are, through the defects of our society and our educational system, unavailable to us without such drugs.

Such a remark applies not only to self-awareness and to intellectual pursuits, but also to perceptions of real people, a vastly enhanced sensitivity to facial expression, intonations, and choice of words which sometimes yields a rapport so close it's as if two people are reading each other's minds. My high is always reflective, peaceable, intellectually exciting, and sociable, unlike most alcohol highs, and there is never a hangover.

Through the years I find that slightly smaller amounts of cannabis suffice to produce the same degree of high, and in one movie theater recently I found I could get high just by inhaling the cannabis smoke which permeated the theater.

There is a very nice self-titering aspect to cannabis. Each puff is a very small dose; the time lag between inhaling a puff and sensing its effect is small; and there is no desire for more after the high is there. I think the ratio, R, of the time to sense the dose taken to the time required to take an excessive dose is an important quantity. R is very large for LSD which I've never taken and reasonably short for cannabis. Small values of R should be one measure of the safety of psychedelic drugs.

When cannabis is legalized, I hope to see this ratio as one of the parameters printed on the pack. I hope that time isn't too distant; the illegality of cannabis is outrageous, an impediment to full utilization of a drug which helps produce the serenity and insight, sensitivity and fellowship so desperately needed in this increasingly mad and dangerous world.

Introduction p. Fingers are not involved, at least directly, in the propagation of the species. The process is random and statistical.

Oh no, there's been an error

From an evolutionary point of view this would be quite extraordinary: why should it have evolved if it had no function? But actually the statement is made on very little evidence. Foretelling disaster is probably not much fun; Pollyanna was much happier than Cassandra. But the Cassandric components of our nature are necessary for survival. Indeed, the standard evolutionary practice of increasing the amount of genetic information as organisms increase in complexity is accomplished by doubling part of the genetic material and then allowing the slow specialization of function of the redundant set.

Skeptical and critical thinking is not a hallmark of the right hemisphere. And unalloyed right-hemisphere doctrines, particularly when they are invented during new and trying circumstances, may be erroneous or paranoid. On the other hand, mere critical thinking, without creative and intuitive insights, without the search for new patterns, is sterile and doomed. To solve complex problems in changing circumstances requires the activity of both cerebral hemispheres: the path to the future lies through the corpus callosum.

The effective pursuit of knowledge requires both functions. There are many hypotheses in physics of almost comparable brilliance and elegance that have been rejected because they did not survive such a confrontation with experiment.

In my view, the human condition would be greatly improved if such confrontations and willingness to reject hypotheses were a regular part of our social, political, economic, religious and cultural lives.

They are hierarchical and ritualistic. Suggestions for change are greeted with suspicion: they imply an unpleasant future variation in ritual and hierarchy: an exchange of one set of rituals for another, or perhaps for a less structured society with fewer rituals.

And yet there are times when societies must change. Much of the difficulty in attempting to restructure American and other societies arises from this resistance by groups with vested interests in the status quo. Significant change might require those who are now high in the hierarchy to move downward many steps. This seems to them undesirable and is resisted. It is difficult to imagine any experiment that would convince leading practitioners of many political or religious philosophies of the superiority of a competing doctrine.

Those who possessed poorly programmed brains eventually did not live long enough to reproduce. There is nothing mysterious about this: smart organisms by and large survive better and leave more offspring than stupid ones.
