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").

A history of the human brain from the big bang, fifteen billion years ago, to the day before yesterday . . . It’s a delight.”— The New York Times After that, we put our complete dragon into a base for shaping and covering with resin. It takes more time to wait for it to get dried. Published in 1977, Dragons was widely hailed by critics from conventional media sources as a “delight” sure to fascinate readers. Some scientifically trained reviewers were decidedly less glowing, however. The Dragons of Eden: Speculations on the Evolution of Human Intelligence is a 1977 book by Carl Sagan, in which the author combines the fields of anthropology, evolutionary biology, psychology, and computer science to give a perspective on how human intelligence may have evolved. Especially, as we have different forms and sizes of the dragon, it takes several days or even weeks to complete all of them without any mistakes. If there is something wrong, we need to spend more time to start again. And of course, it needs not only time but also the patience of our team to make the most perfect one. The love of work is a motivation for our artists to deal with unexpected things.Not accepting the decision of the six Descendants, Aiden challenged Edna to a duel, claiming that whoever won was the worthy owner of Supreme Power. Edna was undeterred and accepted the challenge. The two sides fought fiercely. The ink naturally poured before the resin is completely dry is an important step to create an Eden effect and make our keycap become unique. This step normally takes about 2-4 hours for the ink drops are falling slowly one by one. The reason that makes our Dragons of Eden become one of most favourite keycaps comes from the sophisticated design. In this version 3, we continue to introduce a special design of our awesome creature in the modern fantasy world. A central theme of Sagan's book is the idea that what makes humans special is how we harness the split in our minds. The ability to dream wildly, but also to apply logic and reason to those wild thoughts. The book itself is a vivid example of this capacity. It ends with a firm conviction that the survival of our species depends on education, and shows how the same technologies that threaten our survival can be harnessed to allow children to understand concepts at a young age that were once the purview of accomplished 18th century scientists and mathematicians. And while Machine Learning and Artificial Intelligence are just now experiencing an explosion of interest, Sagan writing in 1977 showed a clear understanding of the ways in which those technologies could someday augment our ability to, among other things, search the galaxies for intelligent life beyond our pale blue dot. (Like most 20th century writers, Sagan didn't fully grasp the effect smartphones would have on our society.) It has not been done for our dragon design. Another challenging work is casting the minor parts such as the dragon’s horns, mane, scales and legs. These small parts play an important role to decide how amazing our dragons are so we need to focus on them. We try to highlight the sharpness and make the contrast to the entire part of the dragon.

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 overcame all our natural predators through weaponry or guile in the eons past. A moment of reflection on our past brings up that question : why did the other humanoids not survive while our ancestors did ? How did they all gt wiped out ? Natural selection could not have been the only answer.This book is one that shook me out of cerebral complacency and like a good author, Sagan opens the cobweb laden windows of my brain and lets the light in. Sagan’s focus is the R complex, part of the “reptilian brain”. It is quite clear that parts of this brain structure are found in reptiles. Reptiles and mammals have an ancient relationship; reptiles originated 500 million years before human beings, so we came into a world that was full of hissing, crawling, terrestrial, arboreal and aquatic reptiles. As Sagan describes, it’s no surprise that many of the world’s foremost civilizations and religions used reptiles as key symbols; from the snake in Eden to the worship of snakes in ancient Egypt to snake symbolism in modern day India, reptiles and human have shared an indelible bond. Reptiles have also often featured as omens in dreams dictating the fates of empires and societies. Some of our reptilian connections raise mundane but fascinating questions; for instance, Sagan wonders whether the shushing sound we make for communicating silence or disapproval is a leftover of the hissing sound of reptiles.In this chapter Sagan famously maps the age of the universe, nearly 14 billion years, into a single year. We see that if the Big Bang starts on January 1st at 12:01 am, then humans don’t arrive to the timeline until December 31st at 10:30 pm, and all of our recorded history can be confined to the final 10 seconds of the year! Powerful stuff. A history of the human brain from the big bang, fifteen billion years ago, to the day before yesterday . . . It's a delight.”—The New York Times However, this gift comes with a price. Humans are the only species that experience pain during childbirth, this is due to the large skull of human babies. While parts are outdated, other parts make for fascinating scientific information that is still just as relevant today as it was in 1977. This book introduces the "Cosmic Calendar", where the entire history of the Universe since the Big Bang is set to scale as if it occurred in one year. The earth did not form until September and all of "recorded" history occurred in the last hour before midnight-exactly the kind of humbling truth that Sagan delivered so well. The parts on primate and early human evolution are fascinating and I imagine would be even more eye-opening to someone who had not been formally educated on those subjects. I love it when Sagan extends the scientific data to social and political issues, and there is plenty of that here, though perhaps less than in some of his other books. Interestingly enough, Sagan points out that dragon myths aren’t just found in the Western world, but are instead a worldwide phenomenon. This may be because of dinosaurs or similar reptiles, which may have resembled dragons.
