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.

El escepticismo tiene por función ser peligroso. Es un desafío a las instituciones establecidas. Si enseñamos a todo el mundo, incluyendo por ejemplo a los estudiantes de educación secundaria, unos hábitos de pensamiento escéptico, probablemente no limitarán su escepticismo a los ovnis, los anuncios de aspirinas y los profetas canalizados de 35.000 años. Quizá empezarán a hacer preguntas importantes sobre las instituciones económicas, sociales, políticas o religiosas. Quizá desafiarán las opiniones de los que están en el poder. ¿Dónde estaremos entonces?

A handful of sand contains about 10,000 grains, more than the number of stars we can see with the naked eye on a clear night. But the number of stars we can see is only the tiniest fraction of the number of stars that are. What we see at night is the merest smattering of the nearest stars. Meanwhile the Cosmos is rich beyond measure: the total number of stars in the universe is greater than all the grains of sand on all the beaches of the planet Earth.
