Description
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, show more 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. show lessTags

El hombre ha avanzado mucho en el camino del conocimiento de sí mismo y de su situación en el universo. Y por primera vez se da cuenta de que está o puede estar en condiciones para entrar en contacto con seres de otros mundos. Esta búsqueda de seres dotados de inteligencia igual o superior a la nuestra en otros lugares del universo constituye una cuestión fundamental, no sólo desde el punto de vista científico sino filosófico y humano. Supone una posibilidad de situar a la humanidad en un contexto cósmico y así dar un paso más en la resolución del eterno problema de quiénes somos, de dónde venimos y qué nos reserva el futuro: un futuro en un universo más amplio de lo que nuestros antepasados podían soñar, tanto en show more extensión como en duración. Este libro contiene las ponencias y conclusiones de un congreso que se celebró en 1971, en la Armenia soviética, y en el que destacados científicos de todo el mundo expusieron sus conocimientos y opiniones sobre la comunicación con inteligencias extraterrestres. La obra, a cargo de Carl Sagan —que ha reunido y elaborado los materiales de dicho congreso—, constituye una exposición completa del estado actual de las investigaciones sobre el posible contacto con seres inteligentes de otros mundos y un punto de partida para cualquier estudio futuro sobre la materia. show less

Author Information

A respected planetary scientist best known outside the field for his popularizations of astronomy, Carl Sagan was born in New York City on November 9, 1934. He attended the University of Chicago, where he received a B.A. in 1954, a B.S. in 1955, and a M.S. in 1956 in physics as well as a Ph.D. in 1960 in astronomy and astrophysics. He has several show more early scholarly achievements including the experimental demonstration of the synthesis of the energy-carrying molecule ATP (adenosine triphosphate) in primitive-earth experiments. Another was the proposal that the greenhouse effect explained the high temperature of the surface of Venus. He was also one of the driving forces behind the mission of the U.S. satellite Viking to the surface of Mars. He was part of a team that investigated the effects of nuclear war on the earth's climate - the "nuclear winter" scenario. Sagan's role in developing the "Cosmos" series, one of the most successful series of any kind to be broadcast on the Public Broadcasting System, and his book The Dragons of Eden (1977) won the Pulitzer Prize in 1978. He also wrote the novel Contact, which was made into a movie starring Jodie Foster. He died from pneumonia on December 20, 1996. (Bowker Author Biography) show less
