    It s very hard to give a review and rating for the entirety of this book From chapter to chapter it feels disjointed and varies quite a bit in both content and quality I seem forced to review the different parts and chapters individually The first part of the book, titled Science and Human Concern and encompassing the first four chapters, showcases Sagan s eloquent and brilliant writing especially well In these chapters I learned new things and gained a new appreciation for Einstein s in It s very hard to give a review and rating for the entirety of this book From chapter to chapter it feels disjointed and varies quite a bit in both content and quality I seem forced to review the different parts and chapters individually The first part of the book, titled Science and Human Concern and encompassing the first four chapters, showcases Sagan s eloquent and brilliant writing especially well In these chapters I learned new things and gained a new appreciation for Einstein s incredible mind One would be hard pressed to argue the book doesn t start off strong The next part, called The Paradoxers , starts of well enough, explaining and refuting various pseudoscientific and paranormal beliefs But in chapter 7 Sagan spends over 50 pages refuting the claims made in a specific book called Worlds in Collision written by a specific author named Velikovsky This would be fine if I were reading Broca s brain 30 years ago when it was published, but as it is I have never heard anyone repeating the ridiculous claims spouted by Velikovsky so I wasn t very interested in their refutations I ended up skimming through most of the chapter This is just one of the ways the book suffers from how dated it is After this, part two continues with a couple good chapters, the first on theological arguments and second on science fiction The next two parts of Broca s Brain are both mostly concerned with astronomy, space exploration, and humanity s future They continue to vary in quality from a great chapter on Robert H Goddard s tireless work towards space exploration to a terribly boring chapter on choosing namesakes for features of other planets The final part skeptically examines religion and does a pretty good job until it ends with a chapter concerning hypothesis that explains religious stories and experiences in terms of subconscious memories of birth that s almost Freudian in its level of wild speculation Broca s Brain is magnificent at times, but at times it s dense enough to make up for it, and overall it just felt too muddled for me to give it a very good rating

    i m amazed that i was able to understand three quarters of this book with little or no help at all from any outside source there were times when i had to use the dictionary or find someone on the internet who can explain physics to a near idiot in the domain even so, i can give myself a pat on the back for this one of course, sagan writes for the masses, and this here is not real science, butlike an introduction to it, a taste. even if it s a really small one for an expert, for someone i m amazed that i was able to understand three quarters of this book with little or no help at all from any outside source there were times when i had to use the dictionary or find someone on the internet who can explain physics to a near idiot in the domain even so, i can give myself a pat on the back for this one of course, sagan writes for the masses, and this here is not real science, butlike an introduction to it, a taste. even if it s a really small one for an expert, for someone like me, who struggles to understand the terms and imagine the actions, it s a step forward but i am so passionate about this subject i love learning about the outer space and if physics is a part of it, then so be it there are few things out there that i consider to beworthy of attention than the mechanics of our universe and i m sure that, throughout the years, i ll be able to understand even

    Miscellaneous writings by Carl Sagan I read it immediately after Cosmos was aired on Doordarshan the national TV channel of India Sagan is a great explainer reading him will automatically engender a love for science

    A re read after 13 years certainly was worth the effort for at least a few chapters Although a lot of information must be now updated considering this being a 1979 updated edition, this book must have been intense at that time An entire section is dedicated to debunking Paradoxers which occupiesthan a quarter of the book, especially on Immanuel Velikovsky s theories.Certain introductory chapters dealing with Why Science , Albert Einstein and about the lack of public education in A re read after 13 years certainly was worth the effort for at least a few chapters Although a lot of information must be now updated considering this being a 1979 updated edition, this book must have been intense at that time An entire section is dedicated to debunking Paradoxers which occupiesthan a quarter of the book, especially on Immanuel Velikovsky s theories.Certain introductory chapters dealing with Why Science , Albert Einstein and about the lack of public education in science were very nice to read.Other chapters that were interesting to read were related to The Solar System and the usage of Nomenclature within it on life in our Solar System based on their atmospheres a chapter based on the Surface and Atmosphere of Titan, the moon of Saturn Climates of Earth and Mars Asteroids and Meteorites Planetary Exploration Communication and Transportation Speeds In defense of Robots and AI the quest for Extraterrestrial Life Views on God and Religion, our Galaxy and the Universe and finally a chapter on the usage of psychedelic drugs and its usage to induce Perinatal Memories while relating it to understand the Origins and Nature of Religion and to Cosmology.If only Mr Sagan have had lived today, I would have loved to read a revised edition of this book now after nearly four decades of its first publication in 1974

    Considering this book was written forty years ago, it s a masterpiece In it, Carl Sagan covers a range of different topics In one whole chapter, which I think is the bulk of this book, Sagan makes a critical analysis of Velikovsky s book, Worlds in Collision Sometimes the borderline between science and pseudoscience is so thin, you have to be a scientist to point it out That being said, in most cases we can apply methods and tools of skepticism and critical thinking to come to a sound decisi Considering this book was written forty years ago, it s a masterpiece In it, Carl Sagan covers a range of different topics In one whole chapter, which I think is the bulk of this book, Sagan makes a critical analysis of Velikovsky s book, Worlds in Collision Sometimes the borderline between science and pseudoscience is so thin, you have to be a scientist to point it out That being said, in most cases we can apply methods and tools of skepticism and critical thinking to come to a sound decision Sagan wisely asserts that skepticism is not denialism or cynicism It s just that you need to ask for sufficient evidence in case of extraordinary claims

    Museums have an inner world that the public never sees In one of these hideaways, Carl Sagan was permitted to view the brain of Paul Broca, a surgeon who died in 1880 As Dr Sagan looked at the cerebral remains of one of his heroes, he had this thought It was difficult to hold Broca s brain without wondering whether in some sense Broca was still in there Sagan wondered at a possible future where technology would allow us to download Broca s memories And then he wrote something that struck Museums have an inner world that the public never sees In one of these hideaways, Carl Sagan was permitted to view the brain of Paul Broca, a surgeon who died in 1880 As Dr Sagan looked at the cerebral remains of one of his heroes, he had this thought It was difficult to hold Broca s brain without wondering whether in some sense Broca was still in there Sagan wondered at a possible future where technology would allow us to download Broca s memories And then he wrote something that struck me In considering the opportunity to literally read a mind, Sagan posited, It would be the ultimate breach of privacy I was a bit awed at Sagan s willingness to troubleshoot the ethics of his own pipedream After all, what if we could tap the intelligence of brilliant men and women, now deceased It s a fascinating thought, but also a troubling one I admired Sagan for volunteering the questionable nature of his own desire for access.The above is just one of many intriguing reflections offered by Carl Sagan in Broca s Brain Reflections on the Romance of Science. This book is a collection of essays, many previously published in magazines With a firm command of both science and humanity, Sagan explores a range of issues related to our existence Especially engrossing, even haunting, are his ruminations on the process of dying Sagan writes with candor about the issues facing our species He does not patronize readers with comfort for comfort s sake, but neither does he gravitate toward sensationalism Sagan s dialogue style is thoughtful and dignified, but with splashes of humor He also throws some pointed jabs at absurd notions that regrettably retain traction in modern society As our world becomes almost wholly dependent on scientific technology, works like this will be an essential frame of reference for laypersons TheI read Sagan and others, theI am convinced that being conversant in science is a matter of civic responsibility.With some technical exceptions, the content of this book is very accessible For those who have already read other works by Carl Sagan, I highly recommend it If you have not yet tried Sagan, I suggest starting with the novel Contact, or getting a hold of his groundbreaking work Cosmos The latter is available on DVD and in book form

    It took me a lottime than I expected, mainly because I kept checking for update information about most of the interesting topics I still love Carl Sagan s writing though.

    I ve been on a Sagan kick, but this was a tough read to get through The book is a little technical, but eventedious in sections, discussing in depth discoveries of the 1950s and 1960s The best parts of the book require a grasping understand of the nature of present day astronomy to compare and contrast with what Sagan thinks will occur Ever the optimist, it is a little disappointing to realize that we have not come close to the explorations that Sagan envisioned in the late 1970s Some I ve been on a Sagan kick, but this was a tough read to get through The book is a little technical, but eventedious in sections, discussing in depth discoveries of the 1950s and 1960s The best parts of the book require a grasping understand of the nature of present day astronomy to compare and contrast with what Sagan thinks will occur Ever the optimist, it is a little disappointing to realize that we have not come close to the explorations that Sagan envisioned in the late 1970s Some of his hopes have been achieved, and he would have been awed by the discoveries made by the Cassini and Huygens probes, making this book bittersweet knowing that he will never have the opportunity to comment on today s discovery A suggestion for future readers would be just to skip the vivisection of Dr Velikovsky, unless you want an example of what would happen to the likes of homeopathy or astrology if scientists truly decided to turn their attention to those false disciplines
