Communication with Extraterrestrial Intelligence

Availability: Ready to download

The first international conference on the problem of extraterrestrial civilizations, and contact with them, was held in September 1971 in Soviet Armenia. The conference was a gathering of specialists working in a wide variety of fields--astronomy, physics, radiophysics, computer science and technology, chemistry, biology, linguistics, archaeology, anthropology, sociology, The first international conference on the problem of extraterrestrial civilizations, and contact with them, was held in September 1971 in Soviet Armenia. The conference was a gathering of specialists working in a wide variety of fields--astronomy, physics, radiophysics, computer science and technology, chemistry, biology, linguistics, archaeology, anthropology, sociology, and history--and included many scientists whose reputations are worldwide. For example, Freeman Dyson, Philip Morrison, and Charles Townes were among the American participants; their Russian counterparts were of comparable distinction. The conference was jointly organized by the U.S. National Academy of Sciences (with assistance from the U.S. National Science Foundation) and the U.S.S.R. Academy of Sciences. Scientists from several other countries also participated.Many aspects of the problem of extraterrestrial civilizations were discussed in detail, and these discussions are fully presented in this book. Particular attention is devoted to the following questions: the plurality of planetary systems in the universe, the origin of life on Earth, the possibility of life arising on cosmic bodies, the origin and evolution of intelligence, the origin and development of technological civilizations, problems in searching for intelligent signals or for evidence of astroengineering activities, and the problems and possible consequences of establishing contact with extraterrestrial civilizations.

    This book has got some very interesting ideas (e.g. sending a signal containing a computer logic diagram instead of a picture, because the former can contain interactive teaching tools and will maintain its topology in the face of signal distortions). But a lot of it was hard to grind through, having not studied physics since college. The names, though! Carl Sagan, Nikolai Kardashev, Frank Drake, Francis Crick (yes, that Crick), Freeman Dyson! These people are v good at thinking about stuff.

    This book essentially consists of the proceedings (e.g., meeting notes and transcriptions) of an international multi-disciplinary conference of scientists from various fields (including astronomy, anthropology, physics, mathematics, computer science, physiology, electrical engineering, molecular biology, etc.) held in Armenia (USSR) in 1971 on the topic of Communication with Extraterrestrial Intelligence (CETI).

Edited by Carl Sagan, each chapter includes presentations and discussions of the different factors of the Drake Equation, along with additional related material on astro-engineering activity, techniques of contact, and the possible message contents of ETI communications, along with concluding chapters on the consequences of contact and conference resolutions. Dyson's essay "The World, The Flesh, and The Devil" in one of the Appendices, including his discussion of "planting" giant biologically engineered trees on comets to make them habitable abodes for human settlement/colonization, and by implication the possibility that aliens might use (interstellar) comets in the same way, is fascinating :-)

    Clásico absoluto en la materia de la búsqueda de civilizaciones extraterrestres. Aunque el paso del tiempo ha dejado muy atrás el conocimiento de los fenómenos astrofísicos de la época sorprende lo actuales que resultan algunos de los debates presentes en el libro. Algunas especulaciones se han convertido en evidencias, otras han pasado de moda y han sido superadas, pero por eso es un clásico repleto de buenas ideas.

    No puedo creer que esta conferencia se haya dado en 1971.
