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

The American system of jurisprudence recognizes a wide range of factors, predispositions, prejudices, and experiences that might cloud our judgment, or affect our objectivity — sometimes even without our knowing it. It goes to great, perhaps even extravagant, lengths to safeguard the process of judgment in a criminal trial from the human weaknesses of those who must decide on innocence or guilt. Even then, of course, the process sometimes fails. Why would we settle for anything less when interrogating the natural world, or when attempting to decide on vital matters of politics, economics, religion, and ethics?

Science is more than a body of knowledge; it is a way of thinking. I have a foreboding of an America in my children’s or grandchildren’s time — when the United States is a service and information economy; when nearly all the key manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what’s true, we slide, almost without noticing, back into superstition and darkness. The dumbing down of America is most evident in the slow decay of substantive content in the enormously influential media, the 30-second sound bites (now down to 10 seconds or less), lowest common denominator programming, credulous presentations on pseudoscience and superstition, but especially a kind of celebration of ignorance. As I write, the number-one videocassette rental in America is the movie Dumb and Dumber. “Beavis and Butthead” remain popular (and influential) with young TV viewers. The plain lesson is that study and learning — not just of science, but of anything — are avoidable, even undesirable.

Öyle garip kavramlarla yetiştirilmişiz ki, bizden birazcık değişik bir kişi ya da toplumla karşılaşınca, onların bize yabancılığı nedeniyle güvensizlik duyuyoruz ya da nefret ediyoruz. Oysa her bir uygarlığın anıtları ve kültürü, insan olmanın değişik biçimde anlatımından başka bir şey değildir. Yerküre-dışı bir ziyaretçi çeşitli insanlar ve insan toplumları arasındaki farklara göz attığında, aramızdaki benzerlikleri farklardan daha çok bulacaktır. Kozmos'u akıllı yaratıklar dolduruyor olabilir. Fakat Darwin'in öğretisi açıktır: Başka bir yerde insana rastlayamazsınız. Yalnızca gezegenimizde vardır insan. Bu küçücük gezegenimizde. Nadir ama tehlikeli bir türüz. Kozmik perspektifte, her birimiz çok değerliyiz. Eğer bir insanın sizinle aynı fikri paylaşmadığını fark ederseniz, aldırmayın, bırakınız bu gezegende yaşamaya devam etsin. Unutmayın, yüz milyar galaksiyi gezip tek bir insan bile bulamayabilirsiniz.
