Carl Sagan

 
 

Carl Edward Sagan
(November 9, 1934 December 20, 1996)
 
was an American astronomer, cosmologist, astrophysicist, astrobiologist, author, science popularizer, and science communicator in
astronomy and other natural sciences.

His contributions were central to the discovery of the high surface temperatures of Venus.

However, he is best known for his contributions
to the scientific research of
extraterrestrial life,
including experimental demonstration of the production
of amino acids from basic chemicals by radiation.

    Sagan assembled the first physical messages that were 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 was one of the few critics of Plato. Sagan said of Plato: "Science and mathematics were to be removed from the hands of the merchants and the artisans. This tendency found its most effective advocate in a follower of Pythagoras named Plato." and "He (Plato) believed that ideas were far more real than the natural world. He advised the astronomers not to waste their time observing the stars and planets. It was better, he believed, just to think about them. Plato expressed hostility to observation and experiment. He taught contempt for the real world and disdain for the practical application of scientific knowledge. Plato's followers succeeded in extinguishing the light of science and experiment that had been kindled by Democritus and the other Ionians." -WikiPedia
