We have entered, almost without noticing, an age of exploration and discovery unparalleled since the Renaissance.
Carl SaganExcept for children (who don't know enough not to ask the important questions), few of us spendtime wondering why nature is the way it is . . .
Carl SaganWe on Earth have just awakened to the great oceans of space and time from which we have emerged. We are the legacy of 15 billion years of cosmic evolution. We have a choice: We can enhance life and come to know the universe that made us, or we can squander our 15 billion-year heritage in meaningless self-destruction. What happens in the first second of the next cosmic year depends on what we do, here and now, with our intelligence and our knowledge of the cosmos.
Carl SaganWe live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.
