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.

Consideraba que había aprobado la prueba por pura casualidad, ya que por azar había respondido bien a numerosas preguntas de elección múltiple. Con escasos conocimientos, solo lo necesario para excluir todas las respuestas menos dos, tenía una posibilidad entre mil de obtener todas las respuestas correctas, se dijo. Para lograr veinte, las posibilidades eran de una entre un millón. Sin embargo, ese mismo test lo habían realizado quizás un millón de jóvenes en todo el país. Alguno había de tener suerte.
