About
Carl Sagan
Carl Edward Sagan (9 November 1934 – 20 December 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect. He testified to the US Congress in 1985 that the greenhouse effect will change the earth's climate system.

More recently, books, especially paperbacks, have been printed in massive and inexpensive editions. For the price of a modest meal you can ponder the decline and fall of the Roman Empire, the origin of species, the interpretation of dreams, the nature of things. Books are like seeds. They can lie dormant for centuries and then flower in the most unpromising soil.
Por regla general, las sociedades humanas no son innovadoras, sino más bien jerárquicas y ritualistas. Cualquier sugerencia de cambio se acoge con recelo, ya que implica la incómoda transformación futura del ritual y la jerarquía imperantes, es decir, la sustitución de una serie de rituales por otra o, tal vez, por una sociedad menos estructurada y regida por un número inferior de rituales. Sin embargo, llega un momento en que es preciso que las sociedades cambien. «Los dogmas de un pasado tranquilo son insuficientes para un presente tumultuoso», aseveró Abraham Lincoln.
