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
«بدلاً من أن نعترف بأننا جهلاء في كثير من المجالات، نميل إلى قول أشياء من قبيل أن الكون غاص بما يجل عن الوصف. فهناك إله للفجوات مُكلف بالمسئولية عن الأشياء التي لم نفهمها بعد. وحينما تحسنت المعرفة الطبية منذ القرن الرابع ق.م. تزايد ما نفهمه وقل ما اضطررنا إلى أن نعزوه إلى التدخل الإلهي — سواء ما يتعلق بأسباب الأمراض أو بعلاجها — فقلت الوفيات عند الولادة ووفيات الأطفال الرضع، وطالت أعمار الناس، وحَسَّن الطب نوعية الحياة بالنسبة للمليارات منا في كل أنحاء العالم.»

From the point of view of a mayfly, human beings are stolid, boring, almost entirely immovable, offering hardly a hint that they ever do anything. From the point of view of a star, a human being is a tiny flash, one of billions of brief lives flickering tenuously on the surface of a strangely cold, anomalously solid, exotically remote sphere of silicate and iron.
