Quotes & Sayings About Uncertainty In Science

This time once again it has been my chief aim to make no sacrifice to an appearance of being simple, complete or rounded off, not to disguise problems and not to deny the existence of gaps and uncertainties. In no other scientific field would it be necessary to boast of such modest intentions. They are universally regarded as self-evident; the public expects nothing else. No reader of an account of astronomy will feel disappointed and contemptuous of the science if he is shown the frontiers at which our knowledge of the universe melts into haziness. Only in psychology is it otherwise. There mankind's constitutional unfitness for scientific research comes fully into the open. What people seem to demand of psychology is not progress in knowledge, but satisfactions of some other sort; every unsolved problem, every admitted uncertainty is made into a reproach against it.
Whoever cares for the science of mental life must accept these injustices along with it. — Sigmund Freud

We must surrender our skepticism only in the face of rock-solid evidence. Science demands a tolerance for ambiguity. Where we are ignorant, we withhold belief. Whatever annoyance the uncertainty engenders serves a higher purpose: It drives us to accumulate better data. This attitude is the difference between science and so much else. Science offers little in the way of cheap thrills. The standards of evidence are strict. But when followed they allow us to see far, illuminating even a great darkness. — Carl Sagan

Sitting there on the heather, on our planetary grain, I shrank from the abysses that opened up on every side, and in the future. The silent darkness, the featureless unknown, were more dread than all the terrors that imagination had mustered. Peering, the mind could see nothing sure, nothing in all human experience to be grasped as certain, except uncertainty itself; nothing but obscurity gendered by a thick haze of theories. Man's science was a mere mist of numbers; his philosophy but a fog of words. His very perception of this rocky grain and all its wonders was but a shifting and a lying apparition. Even oneself, that seeming-central fact, was a mere phantom, so deceptive, that the most honest of men must question his own honesty, so insubstantial that he must even doubt his very existence. — Olaf Stapledon

When he thought I was ready, my father inducted me into the quantum universe. It seemed to contradict all the science I had learned so far: nothing was really held in place. The essential stuff of the universe was nonmatter, pulses of energy and information, flickering in and out of existence. Everything was up for grabs. A table, a chair was a fluid arrangement of probabilities. Sometimes I expected the uncertainty principle to kick in and find strangers masquerading as my parents, or that our house had been razed by some great atomic upheaval. It was about this time I started sleeping with the light on. MANY — Dominic Smith

Every reflection today, whether nihilist or positivist, gives birth, sometimes without knowing it, to
standards that science itself confirms. The quantum theory, relativity, the uncertainty of interrelationships,
define a world that has no definable reality except on the scale of average
greatness, which is our own. The ideologies which guide our world were born in the time of absolute
scientific discoveries. Our real knowledge, on the other hand, only justifies a system of thought based on
relative discoveries. "Intelligence," says Lazare Bickel, "is our faculty for not developing what we think
to the very end, so that we can still believe in reality." Approximative thought is the only creator of
reality. — Albert Camus

Physicists often quote from T. H. White's epic novel The Once and Future King , where a society of ants declares, 'Everything not forbidden is compulsory.' In other words, if there isn't a basic principle of physics forbidding time travel, then time travel is necessarily a physical possibility. (The reason for this is the uncertainty principle. Unless something is forbidden, quantum effects and fluctuations will eventually make it possible if we wait long enough. Thus, unless there is a law forbidding it, it will eventually occur.) — Michio Kaku

I do believe that there is a conflict between science and religion ... the spirit or attitude toward the facts is different in religion from what it is in science. The uncertainty that is necessary in order to appreciate nature is not easily correlated with the feeling of certainty in faith. — Richard P. Feynman

Western science has made nature intelligible in terms of its symmetries and regularities, analyzing its most wayward forms into components of a regular and measurable shape. As a result we tend to see nature and to deal with it as an "order" from which the element of spontaneity has been "screened out." But this order is maya, and the "true suchness" of things has nothing in common with the purely conceptual aridities of perfect squares, circles, or triangles - except by spontaneous accident. Yet this is why the Western mind is dismayed when ordered conceptions of of the universe break down. and when the basic behavior of the physical world is found to be a "principle of uncertainty. — Alan W. Watts

For how shall we fill people with blind faith in the correctness of a doctrine, if we ourselves spread uncertainty and doubt by constant changes in its outward structure? ... Here, too, we can learn by the example of the Catholic Church. Though its doctrinal edifice, and in part quite superfluously, comes into collision with exact science and research, it is none the less unwilling to sacrifice so much as one little syllable of its dogmas ... it is only such dogmas which lend to the whole body the character of a faith. — Adolf Hitler

The Uncertainty Principle states that you can know where a particle is, or you can know where it's going, but you can't know both at the same time. The same, it turns out, is true of people. And when you try, when you look too closely, you get the Observer Effect. By trying to work out what's going on, you're interfering with destiny. A particle can be in two places at once. A particle can interfere with its own past. It can have multiple futures, and multiple pasts. The universe is complicated. — Harriet Reuter Hapgood

In effect, we have redefined the task of science to be the discovery of laws that will enable us to predict events up to the limits set by the uncertainty principle. — Stephen Hawking

One may say that predictions are dangerous particularly for the future. If the danger involved in a prediction is not incurred, no consequence follows and the uncertainty principle is not violated. — Edward Teller

There is a saying about surgeons, meant as a reproof: "Sometimes wrong; never in doubt." But this seemed to me their strength. Each day surgeons are faced with uncertainties. Information is inadequate; the science is ambiguous; one's knowledge and abilities are never perfect. Even with the simplest operation, it cannot be taken for granted that a patient will come through better off - or even alive. Standing at the table my first time, I wondered how the surgeon knew that he would do this patient good, that all the steps would go as planned, that the bleeding would be controlled and infection would not take hold and organs would not be injured. He didn't, of course. But still he cut. — Atul Gawande

In engineering or medical science, a deep understanding of uncertainty can be a matter of life and death. In politics, over-confidence is often the norm; uncertainty is seen as weakness when really it is a vital part of decision making. In this respect, science delivers an important lesson in humility. In — Brian Cox

Science deals in evidence and uncertainty. Religion deals in certainty without evidence. — David Milne

Decision-making is difficult because, by its nature, it involves uncertainty. If there was no uncertainty, decisions would be easy! The uncertainty exists because we don't know the future, we don't know if the decision we make will lead to the best possible outcome. Cognitive science has taught us that relying on our gut or intuition often leads to bad decisions, particularly in cases where statistical information is available. Our guts and our brains didn't evolve to deal with probabilistic thinking. — Daniel Levitin

Yet, the principle of uncertainty is a bad name. In science or outside of it, we are not uncertain. Our knowledge is merely confined within a certain tolerance. We should call it the principle of tolerance. First in the engineering sense. Science has progressed, step by step, the most successful enterprise in the ascent of man, because it has understood that the exchange of information between man and nature, and man and man, can only take place with a certain tolerance. But I also use the word, passionately, about the real world. All knowledge, all information, between human beings, can only be exchanged within a play of tolerance, and that's whether it's in science, or in literature, or in religion, or in politics, or in any form of though that aspires to dogma. — Jacob Bronowski

In his 1923 review of James Joyce Ulysses, T. S. Eliot focused on one of his generation's recurrent anxieties
the idea that art might be impossible in the twentieth century. The reasons that art seemed impossible are many and complex, but they were all related to the collapse of ways of knowing that had served the Western mind at least since the Renaissance and that had received canonical formulation in the seventeenth century in the science of Newton and the philosophy of Descartes. In both science and philosophy, the crisis was essentially epistemological; that is, it was related to radical uncertainty about how we know what we know about the real world. This crisis, disorienting even to specialists, was at once a cause of despair and an incentive for innovation in the arts. — Jewel Spears Brooker

The chemists who uphold dualism are far from being agreed among themselves; nevertheless, all of them in maintaining their opinion, rely upon the phenomena of chemical reactions. For a long time the uncertainty of this method has been pointed out: it has been shown repeatedly, that the atoms put into movement during a reaction take at that time a new arrangement, and that it is impossible to deduce the old arrangement from the new one. It is as if, in the middle of a game of chess, after the disarrangement of all the pieces, one of the players should wish, from the inspection of the new place occupied by each piece, to determine that which it originally occupied. — Auguste Laurent

Science seems to have uncovered a set of laws that, within the limits set by the uncertainty principle, tell us how the universe will develop with time, if we know its state at any one time. These laws may have originally been decreed by God, but it appears that he has since left the universe to evolve according to them and does not now intervene in it. — Stephen Hawking

There is a new science of complexity which says that the link between cause and effect is increasingly difficult to trace; that change (planned or otherwise) unfolds in non-linear ways; that paradoxes and contradictions abound; and that creative solutions arise out of diversity, uncertainty and chaos. — Andy Hargreaves

But just as we can all agree on what is red, even if we will never know if we each see it in the same way, so we can all agree - can't we? - that no matter how confident we may appear to others, inside we are all sobbing, scared and uncertain for much of the time. Or perhaps it's just me.
Oh God, perhaps it really is just me.
Actually it doesn't really matter, when you come to think of it. If it is just me, then you are reading the story of some weird freak. You are free to treat this book like science fiction, fantasy or exotic travel literature. Are there really men like Stephen Fry on this planet? Goodness, how alien some people are. And if I am not alone, then neither are you, and hand in hand we can marvel together at the strangeness of the human condition. — Stephen Fry

So is this being in love? I stay with the moment, waiting to find out, the space between us fluctuating with uncertainty. The only thing I am sure of is that each time his lips leave mine they are right back again. — Kea Alwang

In science fiction, basic doubts featured prominently in the worlds of Philip K. Dick. I knew Phil for 25 years, and he was always getting onto me, a scientist. He was a great fan of quantum uncertainty, epistemology in science, the lot. — Gregory Benford

In reality, both religion and science are expressions of man's uncertainty. Perhaps the paradox is that certainty, whether it be in science or religion, is dangerous. — Robert Winston

The law is a sort of hocus-pocus science, that smiles in yer face while it picks yer pocket; and the glorious uncertainty of it is of mair use to the professors than the justice of it. — Charles Macklin

Science has a culture that is inherently cautious and that is normally not a bad thing. You could even say conservative, because of the peer review process and because the scientific method prizes uncertainty and penalises anyone who goes out on any sort of a limb that is not held in place by abundant and well-documented evidence. — Al Gore

If it is true that an influx of doubt and uncertainty actually marks periods of healthy growth in a science, then evolutionary biology is flourishing today as it seldom has flourished in the past. For biologists collectively are less agreed upon the details of evolutionary mechanics than they were a scant decade ago. Superficially, it seems as if we know less about evolution than we did in 1959, the centennial year of Darwin's on the Origin of Species. — Niles Eldredge

Proof then, has retreated in the face of belief. Science, once heralded as the arbiter of truth, has had its facade of objectivity punctured. Intellectuals may point to the uncertainty of Heisenberg, but generally this has more to do with the growing distrust of statistics and the knowledge that scientists in the pay of governments and multi-nationals are no more objective than their masters. Science, once the avowed enemy of religion, now sees books BT Christian physicists and Taoist mathematicians. Science sells washing powders and status symbols and comes in the form of icons of technological nostalgia. — Phil Hine

We have minds that are equipped for certainty, linearity and short-term decisions, that must instead make long-term decisions in a non-linear, probabilistic world. — Paul Gibbons

Myths, whether in written or visual form, serve a vital role of asking unanswerable questions and providing unquestionable answers. Most of us, most of the time, have a low tolerance for ambiguity and uncertainty. We want to reduce the cognitive dissonance of not knowing by filling the gaps with answers. Traditionally, religious myths have served that role, but today - the age of science - science fiction is our mythology. — Michael Shermer

No one ever said that you would live to see the repercussions of everything you do, or that you have guarantees, or that you are not obliged to wander in the dark, or that everything will be proved to you and neatly verified like something in science. Nothing is: at least nothing that is worthwhile. I didn't bring you up only to move across sure ground. I didn't teach you to think that everything must be within our control or understanding. Did I? For, if I did, I was wrong. I fyou won't take a chance, then the powers you refuse because you cannot explain them, will, as they say, make a monkey out of you. — Mark Helprin
