" "My parents were not scientists. They knew almost nothing about science. But in introducing me simultaneously to skepticism and to wonder, they taught me the two uneasily cohabiting modes of thought that are central to the scientific method. They were only one step out of poverty. But when I announced that I wanted to be an astronomer, I received unqualified support — even if they (as I) had only the most rudimentary idea of what an astronomer does. They never suggested that, all things considered, it might be better to be a doctor or a lawyer.

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
Perhaps when everyone knows that gods come down to Earth, we hallucinate gods; when all of us are familiar with demons, it's incubi and succibi; when fairies are widely accepted, we see fairies; in an age of spiritualism, we encounter spirits; and when the old myths fade and we begin thinking that extraterrestrial beings are plausible, then that's where our hypnogogic imagery tends.
Claro que si uno tuviera un receptor con paso de banda estrecha, y escuchara solo un mínimo margen de frecuencias, estaría obligado a aceptar la constante de tiempo larga. Jamás podríamos detectar una modulación rápida. Eso era una simple consecuencia del Teorema Integral de Fourier, estrechamente vinculado con el Principio de Incertidumbre de Heisenberg.

Vast migrations of people — some voluntary, most not — have shaped the human condition. More of us flee from war, oppression, and famine today than at any other time in human history. As the Earth’s climate changes in the coming decades, there are likely to be far greater numbers of environmental refugees. Better places will always call to us. Tides of people will continue to ebb and flow across the planet. But the lands we run to now have already been settled. Other people, often unsympathetic to our plight, are there before us. *
