We are star stuff harvesting sunlight. - Carl Sagan

"The idea that God is an oversized white male with a flowing beard, who sits in the sky and tallies the fall of every sparrow is ludicrous. But if by 'God,' one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying... it does not make much sense to pray to the law of gravity."

"We've arranged a civilization in which most crucial elements profoundly depend on science and technology. We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster."

"Somewhere, something incredible is waiting to be known."

"One glance at a book and you hear the voice of another person, perhaps someone dead for 1,000 years. To read is to voyage through time."

"The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself."
