Product Information

Cloth "Cloth-bound" generally refers to a hardcover book with cloth covering the outside of the book covers. Reading this book really made me feel at one with science and myself -- the strange organic computer in my head which is my brain. The birth of Christ occurs at 11:59:56 PM, the Renaissance in Europe occurs at 11:59:58 PM, the current time period of man occurs at the first second of New Year’s Day. Sagan received the NASA medals for Exceptional Scientific Achievement and (twice) for Distinguished Public Service, as well as the NASA Apollo Achievement Award.

Carl Sagan served as the David Duncan Professor of Astronomy and Space Sciences and Director of the Laboratory for Planetary Studies at Cornell University. Of particular interest to me was the discussion of human brain evolution from Australopithecus Africanus onwards, and how each species' brain was an improvement on the old, to the detriment of our cousins within the genus.

Or does the metaphor of the serpent refer to the use of the aggressive and ritualistic reptilian component of our brain in the further evolution of the neocortex? But Dragons of Eden is not a polemic against creationism: in fact, the book is chock-full of biblical imagery and mythology, but is used for what should be its true purpose, to understand where humans have been, not where they are or are yet to go. It would appear from this that the construction of an artificial intelligence should begin with a simple core followed by the continued construction of advanced overlays. The New York Times "How can I persuade every intelligent person to read this important and elegant book? The reason Sagan dives deep into the Cosmic Calendar is that he is trying to show that humans are incredibly new in the scale of the universe.

He wrote that it was important for society to allow for such broad and powerful thinkers - multi-disciplinarians, but that the evidence shows a steep 'decline' towards specialisation. While some of the technical information of this book is apparently outdated, it was mentally stimulating and provided some very interesting ideas to chew on for a layman such as myself.

A poor condition book can still make a good reading copy but is generally not collectible unless the item is very scarce. Clipped dust jacket has light wear to top edge of jacket, including short closed tear to front panel. Sagan is quite upbeat about chimp intelligence and he spends a sizable part of the book talking about experiments that reveal chimps’ prowess in using sign language.

Este libro es un recorrido por la historia del cerebro humano realizado por uno de los científicos más prestigiosos de la actualidad. It may be hard to grasp just how old everything in the universe is so Sagan creates a Cosmic Calendar to better comprehend the length of time. Sagan looks at clues from a wide variety of sciences including anthropology, biology, mythology, philosophy, and psychology to support his reasoning.If we had two synapses, then 2 Clearly apes can come quite close to using the kind of simple vocabulary that humans do, so why are humans the only ones which actually crossed the language barrier, profiting from breakthrough linguistic inventions like recursive embedding and complex sentence construction? The final chapter ties it all up into a neat package with his belief in extra-terrestrial intelligence.
