Science Quotes


"We tend to hear much more about the splendors returned than the ships that brought them or the shipwrights. It has always been that way. Even those history books enamored of the voyages of Christopher Columbus do not tell much about the builders of the Nina the Pinta and the Santa Maria or about the principle of the caravel. These spacecraft their designers builders navigators and controllers are examples of what science and engineering set free for well-defined peaceful purposes can accomplish. Those scientists and engineers should be role models for an America seeking excellence and international competitiveness. They should be on our stamps."


"I have been scientifically studying the traits and dispositions of the "lower animals" (so-called,) and contrasting them with the traits and dispositions of man. I find the result profoundly humiliating to me. For it obliges me to renounce my allegiance to the Darwinian theory of the Ascent of Man from the Lower Animals; since it now seems plain to me that that theory ought to be vacated in favor of a new and truer one, this new and truer one to be named the Descent of Man from the Higher Animals."


"In an electroencephalogram, one of her seizures was almost identical to an orgasm... Nothing happened during a seizure that couldn't happen outside one, except that Roselyn was not in control of it and it happened all at once. Since then, she had experienced hundreds of orgasms and dozens of seizures and, though she didn't come close to finding the latter nearly as entertaining as the former, it was always in her mind. In the midst of Dryden's often machine gun lovemaking or her own considerably more directed and soft ministrations, it was always in the back of her mind at the moment of climax-this is a tenth of a seizure, this is a fifth of one."


"It is a West zone planet which by an inexplicable and somewhat suspicious freak of topography consists almost entirely of subtropical coastline. By an equally suspicious freak of temporal relastatics, it is nearly always Saturday afternoon just before the beach bars close. No adequate explanation for this has been forthcoming from the dominant life forms on Ursa Minor Beta, who spend most of their time attempting to achieve spiritual enlightenment by running round swimming pools, and inviting Investigation Officials from the Galactic Geo-Temporal Control Board to 'have a nice diurnal anomaly."


"Evolution is a blind giant who rolls a snowball down a hill. The ball is made of flakes-circumstances. They contribute to the mass without knowing it. They adhere without intention, and without foreseeing what is to result. When they see the result they marvel at the monster ball and wonder how the contriving of it came to be originally thought out and planned. Whereas there was no such planning, there was only a law: the ball once started, all the circumstances that happened to lie in its path would help to build it, in spite of themselves."


"Skeptical scientists often point out, as Carl Sagan has, that the wonders of real science far surpass the supposed wonders of fringe science. I think it is possible to invert that idea, and to say that the wonders of real consciousness far surpass what conventional science admits can exist."


"Doing what has never been done before is intellectually seductive, whether or not we deem it practical."


"I am one of those scientists who feels that it is no longer enough just to get on and do science. We have to devote a significant proportion of our time and resources to defending it from deliberate attack from organised ignorance."


"Science is a first-rate piece of furniture for a man's upper chamber, if he has common sense on the ground floor."


"Science is theology for an atheist."



"For every fact there is an infinity of hypotheses. The more you look the more you see."


"Private enterprise can never lead a space frontier. It's not possible because a space frontier is expensive, it has unknown risks and it has unquantified risks."


"There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact."


"When we look at a solid lump of iron or rock, we are 'really' looking at what is almost entirely empty space. It looks and feels solid and opaque because our sensory systems and brains find it convenient to treat it as solid and opaque. It is convenient for the brain to represent a rock as solid because we can't walk through it. 'Solid' is our way of experiencing things that we can't walk through or fall throug, because of the electromagnetic forces between atoms. 'Opaque' is the experience we have when light bounces off the surface of an object, and none of it goes through."


"It stands to the everlasting credit of science that by acting on the human mind it has overcome man's insecurity before himself and before nature."


"Science is knowledge meeting humility meeting curiosity: ever-evolving, always learning. Atheism is often but knowledge meeting arrogance: a masquerade under the wing of the beauty of science. Religion is infamously a weight under the one wing; then under the other is atheism, the championed masquerade."


"Perhaps if one less dragonfly had drowned in the Carboniferous swamps, the intelligent organisms on our planet today would have feathers and teach their young in rookeries. The pattern of evolutionary causality is a web of astonishing complexity; the incompleteness of our understanding humbles us."


"You cannot eat apples planted from seeds. They must be grafted, cloned."


"I bet you could sometimes find all the mysteries of the universe in someone's hand."


"Science has taught us, against all intuition, that apparently solid things like crystals and rocks are really almost entirely composed of empty space. And the familiar illustration is the nucleus of an atom is a fly in the middle of a sports stadium, and the next atom is in the next sports stadium."


"Billions of years from now our sun, then a distended red giant star, will have reduced Earth to a charred cinder. But the Voyager record will still be largely intact, in some other remote region of the Milky Way galaxy, preserving a murmur of an ancient civilization that once flourished - perhaps before moving on to greater deeds and other worlds - on the distant planet Earth."



"If you believe in science, like I do, you believe that there are certain laws that are always obeyed."


"Numbers and more numbers...the future of mankind has come down to decimals. I guess you will figure that out, eventually."


"In other studies you go as far as other have gone before you, and there is nothing more to know; but in a scientific pursuit there is continual food for discovery and wonder."


"How is it that hardly any major religion has looked at science and concluded, "This is better than we thought! The Universe is much bigger than our prophets said, grander, more subtle, more elegant? Instead they say, "No, no, no! My god is a little god, and I want him to stay that way. A religion, old or new, that stressed the magnificence of the Universe as revealed by modern science might be able to draw forth reserves of reverence and awe hardly tapped by the conventional faiths."


"Science is based on experiment, on a willingness to challenge old dogma, on an openness to see the universe as it really is. Accordingly, science sometimes requires courage - at the very least the courage to question the conventional wisdom."


"I'm frequently asked, "Do you believe there's extraterrestrial intelligence?" I give the standard arguments- there are a lot of places out there, the molecules of life are everywhere, I use the word billions, and so on. Then I say it would be astonishing to me if there weren't extraterrestrial intelligence, but of course there is as yet no compelling evidence for it.Often, I'm asked next, "What do you really think?"I say, "I just told you what I really think.""Yes, but what's your gut feeling?"But I try not to think with my gut. If I'm serious about understanding the world, thinking with anything besides my brain, as tempting as that might be, is likely to get me into trouble. Really, it's okay to reserve judgment until the evidence is in."


"I think that at that time none of us quite believed in the Time Machine. The fact is, the Time Traveler was one of those men who are too clever to be believed: you never felt that you saw all round him; you always suspected some subtle reserve, some ingenuity in ambush, behind his lucid frankness. Had Filby shown the model and explained the matter in the Time Traveller's words, we should have shown him far less skepticism. For we should have perceived his motives; a pork butcher could understand Filby."


"There is something stunningly narrow about how the Anthropic Principle is phrased. Yes, only certain laws and constants of nature are consistent with our kind of life. But essentially the same laws and constants are required to make a rock. So why not talk about a Universe designed so rocks could one day come to be, and strong and weak Lithic Principles? If stones could philosophize, I imagine Lithic Principles would be at the intellectual frontiers."



"It looks as if the offspring have eyes so that they can see well (bad, teleological, backward causation), but that's an illusion. The offspring have eyes because their parents' eyes did see well (good, ordinary, forward causation)."


"The form that an animal's subjective experience takes will be a property of the internal computer model. That model will be designed, in evolution, for its suitability for useful internal representation, irrespective of the physical stimuli that come to it from outside. Bats and we need the same kind of internal model for representing the position of objects in three-dimensional space. The fact that bats construct their internal model with the aid of echoes, while we construct ours with the aid of light, is irrelevant."



"We must develop as quickly as possible technologies that make possible a direct connection between brain and computer, so that artificial brains contribute to human intelligence rather than opposing it."
