" "La Unión Soviética se anexionó por la fuerza Letonia, Lituania, Estonia y partes de Finlandia, Polonia y Rumania; ocupó y sometió a un régimen comunista a Polonia, Rumania, Hungría, Mongolia, Bulgaria, Checoslovaquia, Alemania oriental y Afganistán, y sofocó el alzamiento de los obreros de Alemania oriental en 1953, la revolución húngara de 1956 y la tentativa checa de introducir en 1968 el glasnost y la perestroika. Dejando aparte las guerras mundiales y las expediciones para combatir la piratería o el tráfico de esclavos, Estados Unidos ha perpetrado invasiones e intervenciones armadas en otros países en más de 130 ocasiones*, incluyendo China (18 veces), México (13), Nicaragua y Panamá (9 cada uno), Honduras (7), Colombia y Turquía (6 en cada país), República Dominicana, Corea y Japón (5 cada uno), Argentina, Cuba, Haití, el reino de Hawai y Samoa (4 cada uno), Uruguay y Fiji (3 cada uno), Granada, Puerto Rico, Brasil, Chile, Marruecos, Egipto, Costa de Marfil, Siria, Irak, Perú, Formosa, Filipinas, Camboya, Laos y Vietnam. La mayoría de estas incursiones han sido escaramuzas para mantener gobiernos sumisos o proteger propiedades e intereses de empresas estadounidenses, pero algunas han sido mucho más importantes, prolongadas y cruentas.
* Esta lista, que suscitó una cierta sorpresa cuando fue publicada en Estados Unidos, se basa en recopilaciones de la Comisión de fuerzas armadas de la cámara de representantes.

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.

Kepler found something different for elliptical orbits: As the planet moves along its orbit, it sweeps out a little wedge-shaped area within the ellipse. When it is close to the Sun, in a given period of time it traces out a large arc in its orbit, but the area represented by that arc is not very large because the planet is then near the Sun. When the planet is far from the Sun, it covers a much smaller arc in the same period of time, but that arc corresponds to a bigger area because the Sun is now more distant. Kepler found that these two areas were precisely the same no matter how elliptical the orbit: the long skinny area, corresponding to the planet far from the Sun, and the shorter, squatter area, when the planet is close to the Sun, are exactly equal. This was Kepler’s second law of planetary motion: Planets sweep out equal areas in equal times.
