" "I don't want to believe. I want to know.
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.

At the heart of science is an essential balance between two seemingly contradictory attitudes - an openness to new ideas, no matter how bizarre or counterintuitive, and the most ruthlessly skeptical scrutiny of all ideas, old and new. This is how deep truths are winnowed from deep nonsense. The collective enterprise of creative thinking and skeptical thinking, working together, keeps the field on track. Those two seemingly contradictory attitudes are, though, in some tension.

Для многих американцев коммунизм – это бедность, отсталость, ГУЛАГ в наказание за искренность, жестокое подавление человеческого духа и безудержное стремление завоевать весь мир. Для многих советских людей капитализм – это бездушная и ненасытная алчность, расизм, война, экономическая нестабильность и всемирный заговор богатых против бедных. Это, хотя они и возникли не на пустом месте, карикатуры, которым действия Советов и Америки со временем придали определенную достоверность и убедительность.
