" "We knew the Moon from our earliest days. It was there when our ancestors descended from the trees into the savannahs, when we learned to walk upright, when we first devised stone tools, when we domesticated fire, when we invented agriculture and built cities and set out to subdue the Earth.
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.

Hablamos de ganar y perder una guerra con la misma naturalidad con que se habla de ganar y perder un partido. En un anuncio televisivo del ejército norteamericano aparece un carro de combate que destruye a otro en unas maniobras, después de lo cual el jefe del vehículo victorioso dice: «Cuando ganamos, no gana una sola persona, sino todo el equipo.» La relación entre deporte y combate resulta por demás clara. Los fans (abreviatura de «fanáticos») llegan a cometer toda clase de desmanes, incluso a matar, cuando se sienten vejados por la derrota de su equipo, se les impide celebrar la victoria o consideran que el arbitro ha cometido una injusticia.
