I have been reading Carl Sagan for months, and I have watched his famous show "Cosmos" all 13 episodes. His way of talking about science is like magical. He really was one of the most succesful scientists in XX. century. His belief to the humanity, his support for the real way of science and his sceptical stance is what the Earth needs most today, and will be tomorrow. I hope there will be more Carl Sagan's in the future...
I'd like to share some of the links about Carl Sagan:
