Beschreibung | Carl Edward Sagan (/ˈseɪɡən/; SAY-gən; November 9, 1934 – December 20, 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. |

Personally, I would be delighted if there were a life after death, especially if it permitted me to continue to learn about this world and others, if it gave me a chance to discover how history turns out.
Science is a way of thinking much more than it is a body of knowledge.
Imagination will often carry us to worlds that never were. But without it we go nowhere.
I am often amazed at how much more capability and enthusiasm for science there is among elementary school youngsters than among college students.
The brain is like a muscle. When it is in use we feel very good. Understanding is joyous.
