Carl Sagan Quotes

Sagan, Carl. Cosmos. Random House, 1980, p. 281.
There was the beginning of a major debate in the advanced countries over the notion of copyright to protect authors and knowledge being a public property. The solution for America and most nations was to allow copyright protection for the specific expression of the knowledge but not the knowledge itself. You cannot copyright an idea or the laws of science—just the way they are expressed. Therefore all are free to discuss the knowledge and also write about it.
Carl Edward Sagan 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 intended to be understood by any extraterrestrial intelligence that might find them.
