Science Quotes

“History is, in its essentials, the science of change. It knows and it teaches that it is impossible to find two events that are ever exactly alike, because the conditions from which they spring are never identical.”

“It can also be useful to politics, enabling that science to discover how much of it is no more than verbal construction, myth, literary tops. Politics, like literature, must above all know itself and distrust itself. As a final observation, I should like to add that it is impossible today for anyone to feel innocent, if in whatever we do or say we can discover a hidden motive - that of a white man, or a male, or the possessor of a certain income, or a member of a given economic system, or a sufferer from a certain neurosis - this should not induce in us either a universal sense of guilt or an attitude of universal accusation. When we become aware of our disease or of our hidden motives, we have already begun to get the better of them. What matters is the way in which we accept our motives and live through the ensuing crisis. This is the only chance we have of becoming different from the way we are - that is, the only way of starting to invent a new way of being.”

“Either god exists or it doesn’t exist. If a god does exist, it either interacts with the universe in some detectable way or it doesn’t. If it doesn’t, that god is indistinguishable from a non-existent god. That only leaves a god who interacts with the universe in some detectable way. But if science, which is the greatest realization of the use of our senses to, you know, detect things, hasn’t found this god, that doesn’t say much for individuals.In short, the god you’ve created is, in fact, undetectable by science. The limits of science are not the province of religious knowledge. Where science is ignorant, so is religion. The only difference is that religion lacks the integrity of science.”

“Science has always been my preoccupation and when you think a breakthrough is possible, it is terribly exciting.”

“The social function of economic science consists precisely in developing soundeconomic theories and in exploding the fallacies of vicious reasoning. In the pursuit ofthis task the economist incurs the deadly enmity of all mountebanks and charlatanswhose shortcuts to an earthly paradise he debunks. The less these quacks are able toadvance plausible objections to an economist’s argument, the more furiously do theyinsult them.”

“From this distant vantage point, the Earth might not seem of particular interest. But for us, it's different. Consider again that dot. That's here, that's home, that's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves. The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.”

“Science and mythology were the topics which fascinated me since my early childhood.”

“In science, work (W) is done when force (F) move a body through a distance (D). It is the same with our every day affairs. When you don't progress, no work is done irrespective of the force (power) you have”

“When the organization called soul is free, moving and operative, initial as well as terminal, it is spirit. Qualities are both static, substantial, and transitive. Spirit quickens; it is not only alive, but spirit gives life. Animals are spirited, but man is a living spirit. He lives in his works and his works do follow him. Soul is form, spirit informs. It is the moving function of that of which soul is the substance. Perhaps the words soul and spirit are so heavily laden with traditional mythology and sophisticated doctrine that they must be surrendered; it may be impossible to recover for them in science and philosophy the realities designated in idiomatic speech. But the realities are there, by whatever names they be called.”

“What science fiction does is take what might be possible someday and examine what might happen if it were - the drawbacks and the positive things.”

“It may be asked how I know that there are any Reals. If this hypothesis is the sole support of my method of inquiry, my method of inquiry must not be used to support my hypothesis. The reply is this: 1. If investigation cannot be regarded as proving that there are Real things, it at least does not lead to a contrary conclusion; but the method and the conception on which it is based remain ever in harmony. No doubts of the method, therefore, necessarily arise from its practice, as is the case with all the others. 2. The feeling which gives rise to any method of fixing belief is a dissatisfaction at two repugnant propositions. But here already is a vague concession that there is some one thing which a proposition should represent. Nobody, therefore, can really doubt that there are Reals, for, if he did, doubt would not be a source of dissatisfaction. The hypothesis, therefore, is one which every mind admits. So that the social impulse does not cause men to doubt it. 3. Everybody uses the scientific method about a great many things, and only ceases to use it when he does not know how to apply it. 4. Experience of the method has not led us to doubt it, but, on the contrary, scientific investigation has had the most wonderful triumphs in the way of settling opinion. These afford the explanation of my not doubting the method or the hypothesis which it supposes; and not having any doubt, nor believing that anybody else whom I could influence has, it would be the merest babble for me to say more about it. If there be anybody with a living doubt upon the subject, let him consider it.”

“The theory of undirected evolution is already dead, but the work of science continues.”

“We don't regard any scientific theory as the absolute truth.”

“I had never seen much of Star Trek, or any other science fiction, before I was cast. But Seven's wonderful.”

“Teachers seeking to 'teach the controversy' over Darwinian evolution in today's climate will likely be met with false warnings that it is unconstitutional to say anything negative about Darwinian evolution. Students who attempt to raise questions about Darwinism, or who try to elicit from the teacher an honest answer about the status of intelligent design theory will trigger administrators' concerns about whether they stand in Constitutional jeopardy. A chilling effect on open inquiry is being felt in several states already, including Ohio. South Carolina, and Pennsylvania. [District Court] Judge Jones's message is clear: give Darwin only praise, or else face the wrath of the judiciary.”

“I myself have dreamed up a structure intermediate between Dyson spheres and planets. Build a ring 93 million miles in radius - one Earth orbit - around the sun. If we have the mass of Jupiter to work with, and if we make it a thousand miles wide, we get a thickness of about a thousand feet for the base.And it has advantages. The Ringworld will be much sturdier than a Dyson sphere. We can spin it on its axis for gravity. A rotation speed of 770 m/s will give us a gravity of one Earth normal. We wouldn't even need to roof it over. Place walls one thousand miles high at each edge, facing the sun. Very little air will leak over the edges.Lord knows the thing is roomy enough. With three million times the surface area of the Earth, it will be some time before anyone complains of the crowding.”

“Emergent behaviors rely on computational geometry and scale.”

“From a purely positivist point of view, man is the most mysterious and disconcerting of all the objects met with by science.”

“Maybe we could think of science as being like a nuclear chain reaction in which people and ideas bounce off each other, and if critical mass is reached, a new field is formed.”

“But you can’t be a scientist if you’re uncomfortable with ignorance, because scientists live at the boundary between what is known and unknown in the cosmos. This is very different from the way journalists portray us. So many articles begin, “Scientists now have to go back to the drawing board.” It’s as though we’re sitting in our offices, feet up on our desks—masters of the universe—and suddenly say, “Oops, somebody discovered something!” No. We’re always at the drawing board. If you’re not at the drawing board, you’re not making discoveries. You’re not a scientist; you’re something else. The public, on the other hand, seems to demand conclusive explanations as they leap without hesitation from statements of abject ignorance to statements of absolute certainty.”
