Carl Sagan's Cosmic Connection: An Extraterrestrial Perspective pdf

Carl Edward Sagan was born on the 9th of November 1934 in Brooklyn, USA. An American astronomer is one of the most prominent contributors to the simplification of astronomy, astrophysics and other natural sciences. He also played an important role in the creation of the US space agency NASA. He played a leading role in promoting the search for intelligent creatures outside the globe. He studied physics at the University of Chicago, and in 1960 received the title of Doctor of Astronomy and Astrophysics. He taught at Harvard University, in 1968 he moved to Cornell University, where he became a university professor in 1971. Sagan edited and presented the television program "The Universe", in which he explained astronomy, and the program was shown in many countries. He has been awarded the NASA Medal (twice), the Arster Medal, and the Pulitzer Prize. He wrote a novel Tawassul in 1985 and was represented in a movie in 1997. The most important thing that distinguishes Sagan is his major contributions to the simplification of space and astronomy sciences to the general public, and this may have led to the success of most of his books, most notably: 1- The Universe 2- Planet Earth A pale blue dot 3- Billions and Billions 4 - A world inhabited by demons 5 - Dragons of Eden Sagan believed that the universe contained one or more life outside the framework of planet Earth. This is based on the enormous size of the universe, and his idea simply says that the possibility of the conditions suitable for life in a place other than planet Earth is possible, as long as we are talking about a universe that includes countless numbers of galaxies, stars and planets. He also believed that prime numbers are cosmic numbers. Sagan passed away on December 20, 1996

Carl Sagan's Cosmic Connection: An Extraterrestrial Perspective pdf by Carl Sagan

In 1973, Carl Sagan published The Cosmic Connection, a daring view of the universe, which rapidly became a classic work of popular science and inspired a generation of scientists and enthusiasts. This seminal work is reproduced here for a whole new generation to enjoy. In Sagan's typically lucid and lyrical style, he discusses many topics from astrophysics and solar system science, to colonization, terraforming and the search for extraterrestrials. Sagan conveys his own excitement and wonder, and relates the revelations of astronomy to the most profound human problems and concerns: issues that are just as valid today as they were thirty years ago. New to this edition are Freeman Dyson's comments on Sagan's vision and the importance of the work, Ann Druyan's assessment of Sagan's cultural significance as a champion of science, and David Morrison's discussion of the advances made since 1973 and what became of Sagan's predictions. Who knows what wonders this third millennium will reveal, but one thing is certain: Carl Sagan played a unique role in preparing us for them.
