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.

Additional quotes by Carl Sagan

«بينما يُنظر إلى القليل من العلماء على أنهم دخلاء ينتقدون بجسارة أدواء المجتمع، ويقدمون تحذيرات مبكرة من الكوارث التكنولوجية المحتملة؛ فإن الكثيرين ينظر إليهم باعتبارهم انتهازيين خانعين أو باعتبارهم المصدر الطيع للأرباح المكدسة وأسلحة الدمار الشامل من دون أن يُلقوا بالًا للعواقب طويلة المدى. وتُعتبر الأخطار التكنولوجية التي يقدمها لنا العلم، وكذلك تحديه الضمني للحكمة المنقولة إلينا ممن سبقونا وما ندركه من صعوبة في تناول العلم، كلها أسباب تحدو ببعض الناس إلى عدم الثقة في العلم، والتكنولوجيا.»

Si la calidad de la educación que uno tiene a su alcance es inadecuada, si a uno le enseñan a memorizar al pie de la letra y no a pensar, si el contenido de lo que se nos da para leer viene de una cultura casi ajena, la alfabetización puede ser un camino lleno de obstáculos.

Of all the planets, moons, asteroids, and comets in our Solar System, there is fire only on Earth — because there are large amounts of oxygen gas, O2, only on Earth. Fire was, much later, to have profound consequences for life and intelligence. One thing leads to another.
