" "You can't convince a believer of anything; for their belief is not based on evidence, it's based on a deep seated need to believe
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.

Може би някой ще изтълкува това мое твърдение като твърде широко, но аз смятам, че правим наука всеки път когато критикуваме самите себе си и проверяваме идеите си спрямо околния свят. Обратното - когато сме самодоволни и безкритични към себе си, когато не правим разлика между очаквания и факти, тогава рискуваме да се плъзнем към псевдонаука и суеверие.
