“The American and Russian capabilities in space science and technology mesh; they interdigitate. Each is strong where the other is weak. This is a marriage made in heaven - but one that has been surprisingly difficult to consummate.”

“We have designed our civilization based on science and technology and at the same time arranged things so that almost no one understands anything at all about science and technology. This is a clear prescription for disaster”

“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.”

“We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.”

“We've arranged a global 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. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.”

“We inhabit a universe where atoms are made in the centers of stars; where each second a thousand suns are born; where life is sparked by sunlight and lightning in the airs and waters of youthful planets; where the raw material for biological evolution is sometimes made by the explosion of a star halfway across the Milky Way; where a thing as beautiful as a galaxy is formed a hundred billion times - a Cosmos of quasars and quarks, snowflakes and fireflies, where there may be black holes and other universe and extraterrestrial civilizations whose radio messages are at this moment reaching the Earth. How pallid by comparison are the pretensions of superstition and pseudoscience; how important it is for us to pursue and understand science, that characteristically human endeavor. ”

“Dreams are associated with a state called REM sleep, the abbreviation standing for rapid eye movement. The REM state is strongly correlated with sexual arousal. Experiments have been performed in which sleeping subjects are awakened whenever REM state emerges, while members of a control group are awakened just as often each night but not when they're dreaming. After some days, the control group is a little groggy, but the experimental group - the ones who are prevented from dreaming - is hallucinating in daytime. It's not that a few people with a particular abnormality can be made to hallucinate in this way; anyone is capable of hallucinations.”
