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
"Frequentemente me perguntam: "Você acredita que existe inteligência exraterrestre?" Respondo com os argumentos padrões - há muitos lugares no espaço, as moléculas da vida estão por toda parte, emprego a palavra bilhões, e assim por diante. Depois digo que ficaria espantado senão houvesse inteligência extraterrestre, mas que ainda não há absolutamente nenhuma evidência convincente de que ela existe.
Muitas vezes me perguntam a seguir:
-O que você realmente acha?
Respondo:
-Acabei de lhe dizer o que realmente acho.
-Sim, mas qual é a sua opinião visceral?
Mas eu tento não pensar com as minhas vísceras. Se levo a sério minha tentativa de compreender o mundo, pensar com algum órgão que não seja o cérebro, por mais tentador que possa ser, provavelmente complicará a minha vida. Na verdade, é correto guardar a opinião para quando houver evidências."

I find many adults are put off when young children pose scientific questions. Why is the Moon round? the children ask. Why is grass green? What is a dream? How deep can you dig a hole? When is the world’s birthday? Why do we have toes? Too many teachers and parents answer with irritation or ridicule, or quickly move on to something else: ‘What did you expect the Moon to be, square?’ Children soon recognize that somehow this kind of question annoys the grown-ups. A few more experiences like it, and another child has been lost to science. Why adults should pretend to omniscience before 6-year-olds, I can’t for the life of me understand. What’s wrong with admitting that we don’t know something? Is our self-esteem so fragile?
