Quotes & Sayings About Practical Science

Mystical Alchemy is a personal science, a sublime and effective system of Self-Initiation. Only you, as a single individual, can calculate and follow your way up the Great Mountain of Hermetic Attainment. It is entirely a matter of your own practical application and devotion. All essential guidance is within you, in the inmost center of your heart where your own Holy Guardian Angel, or Inner Self, resides. To depend upon any other thing than your own Holy Guardian Angel to accomplish the Great Work is to insult your Angel who is with you to instruct and guide you. All essential wisdom by which to achieve the Great Work is to be ascertained only within you; nowhere else will you find the Truth. — David Cherubim

Truth is of no practical value to mankind save as it affects terrestrial phenomena, hence the discoveries of science should be concealed or glossed over wherever they conflict with orthodoxy. — H.P. Lovecraft

If I say I am not a politician, it is because I did not go to school to do political science. But at the end of the day, I think we are all born politicians. It's practical. All you gotta do is practice. — George Weah

Secular humanism is avowedly non-religious. It is a eupraxsophy (good practical wisdom), which draws its basic principles and ethical values from science, ethics, and philosophy. — Paul Kurtz

Throughout history, people have studied pure science from a desire to understand the universe rather than practical applications for commercial gain. But their discoveries later turned out to have great practical benefits. — Stephen Hawking

Aside from its importance to many branches of science, a knowledge of the oceans has a practical value for mankind. The intelligent development of our fishing industries, the laying of oceanic cables, the proper construction of harbor-works, oceanic commerce and navigation, as well as long-range weather forecasting, are all dependent on an understanding of the ocean. — Paul J. H. Schoemaker

Gradually, ... the aspect of science as knowledge is being thrust into the background by the aspect of science as the power of manipulating nature. It is because science gives us the power of manipulating nature that it has more social importance than art. Science as the pursuit of truth is the equal, but not the superior, of art. Science as a technique, though it may have little intrinsic value, has a practical importance to which art cannot aspire. — Bertrand Russell

It does not help that some politicians and journalists assume the public is interested only in those aspects of science that promise immediate practical applications to technology or medicine. — Steven Weinberg

Farmers were always generalists. They had to know science and commerce and all sorts of practical things. — Rush D. Holt Jr.

To mix science up with philosophy is only to produce a philosophy that has lost all its ideal value and a science that has lost all its practical value. It is for my private physician to tell me whether this or that food will kill me. It is for my private philosopher to tell me whether I ought to be killed. — Gilbert K. Chesterton

One important idea is that science is a means whereby learning is achieved, not by mere theoretical speculation on the one hand, nor by the undirected accumulation of practical facts on the other, but rather by a motivated iteration between theory and practice. — George E.P. Box

Science is not simply a matter of observing the world, experimenting with its elements and drawing reasonable conclusions. Otherwise, we would have to recognize children, so-called primitives and a good many animals as excellent scientists. But the practical experiments carried out by all of us every day lack a few necessary factors, the first and most important of which is the concept of the universe as a single entity operating under universal, rational, knowable laws. Without this foundation, science cannot operate as such. — Wolfi Landstreicher

We must give as much weight to the arousal of the emotions and to the expression of moral and aesthetic values as we now give to science, to invention, to practical organization. One without the other is impotent. — Lewis Mumford

There cannot be a greater mistake than that of looking superciliously upon practical applications of science. The life and soul of science is its practical application ... — Lord Kelvin

For three decades and longer we have been developing the ideas, science, and technological wherewithal to build a sustainable society. The public knows of these things only in fragments, but not as a coherent and practical agenda indeed the only practical course available. That is our fault and we should start now to put a positive agenda before the public that includes the human and economic advantages of better technology, integrated planning, coherent purposes, and foresight. — David W. Orr

In practical life we are compelled to follow what is most probable ; in speculative thought we are compelled to follow truth. — Baruch Spinoza

For it is necessary in every practical science to proceed in a composite (i.e. deductive) manner. On the contrary in speculative science, it is necessary to proceed in an analytical manner by breaking down the complex into elementary principles. — Thomas Aquinas

[ ... ] from what I'd been able to ascertain online, the Swiss were a reassuringly practical people. They had a long, proud history of staying out of wars, preferring to devote themselves to more constructive endeavours like science, secure banking and building extremely accurate clocks. — Gavin Extence

[...] if truth be told, evolution hasn't yielded many practical or commercial benefits. Yes, bacteria evolve drug resistance, and yes, we must take countermeasures, but beyond that there is not much to say. Evolution cannot help us predict what new vaccines to manufacture because microbes evolve unpredictably. But hasn't evolution helped guide animal and plant breeding? Not very much. Most improvement in crop plants and animals occurred long before we knew anything about evolution, and came about by people following the genetic principle of 'like begets like'. Even now, as its practitioners admit, the field of quantitative genetics has been of little value in helping improve varieties. Future advances will almost certainly come from transgenics, which is not based on evolution at all.
[review of The Evolving World: Evolution in Everyday Life, Nature 442, 983-984 (31 August 2006)] — Jerry A. Coyne

Distinctiveness of This Book The book claims to be distinctive in several ways. First, it presents the breadth of case study research and its scholarly heritage, but also at a detailed and practical level. Other works do not offer as comprehensive a combination. Thus, the earlier versions of this book have been used as a complete portal to the world of case study research. Among its most distinctive features, the book provides a workable technical definition of the case study as a research method and its differentiation from other social science research methods (Chapter 1), an extensive discussion of case study designs (Chapter 2), and a continually expanding presentation of case study analysis techniques (Chapter 5 — Robert K. Yin

The more we want it to be true, the more careful we have to be. No witness's say-so is good enough. People make mistakes. People play practical jokes. People stretch the truth for money or attention or fame. People occasionally misunderstand what they're seeing. People sometimes even see things that aren't there. — Carl Sagan

So far I have been speaking of theoretical science, which is an attempt to understand the world. Practical science, which is an attempt to change the world, has been important from the first, and has continually increased in importance, until it has almost ousted theoretical science from men's thoughts. — Bertrand Russell

Reason drives your search to make sense of the world by pushing you to ask why things are as they are. For theoretical reason, the outcome of that search becomes science; for practical reason, the outcome is a more just world. — Susan Neiman

From the Vedas we learn a practical art of surgery, medicine, music, house building under which mechanized art is included. They are encyclopedia of every aspect of life, culture, religion, science, ethics, law, cosmology and meteorology. — William James

The step between practical and theoretic science, is the step between the miner and the geologist, the apocathecary and the chemist. — John Ruskin

The object of the engine is in fact to give the utmost practical efficiency to the resources of numerical interpretations of the higher science of analysis, while it uses the processes and combinations of this latter. — Ada Lovelace

The science of politics is the one science that is deposited by the streams of history, like the grains of gold in the sand of a river; and the knowledge of the past, the record of truths revealed by experience, is eminently practical, as an instrument of action and a power that goes to making the future. — Lord Acton

The influence of electricity in producing decompositions, although of inestimable value as an instrument of discovery in chemical inquiries, can hardly be said to have been applied to the practical purposes of life, until the same powerful genius [Davy] which detected the principle, applied it, by a singular felicity of reasoning, to arrest the corrosion of the copper-sheathing of vessels ... this was regarded as by Laplace as the greatest of Sir Humphry's discoveries. — Charles Babbage

I believe there exists, & I feel within me, an instinct for the truth, or knowledge or discovery, of something of the same nature as the instinct of virtue, & that our having such an instinct is reason enough for scientific researches without any practical results ever ensuing from them. — Charles Darwin

Political Economy as a branch of science is extremely modern; but the subject with which its enquiries are conversant has in all ages necessarily constituted one of the chief practical interests of mankind. — John Stuart Mill

That is how the atom is split. But what does it mean ? To us who think in terms of practical use it means - Nothing ! — Peter Ritchie Calder

Although human ingenuity may devise various inventions which, by the help of various instruments, answer to one and the same purpose, yet will it never discover any inventions more beautiful, more simple or more practical than those of nature, because in her inventions there is nothing lacking and nothing superfluous; and she makes use of no counterpoise when she constructs the limbs of animals in such a way as to correspond to the motion of their bodies, but she puts into them the soul of the body. — Leonardo Da Vinci

Interspirituality is essentially an agent of a universal mysticism and integral spirituality. We often walk the interspiritual or intermystical path in an intuitive attempt to reach a more complete truth. That final integration, a deep convergence, is an integral spirituality. Bringing together all the great systems of spiritual wisdom, practice, insight, reflection, experience, and science provides a truly integral understanding of spirituality in its practical application in our lives, regardless of our tradition. — Wayne Teasdale

It must be for truth's sake, and not for the sake of its usefulness to humanity, that the scientific man studies Nature. The application of science to the useful arts requires other abilities, other qualities, other tools than his; and therefore I say that the man of science who follows his studies into their practical application is false to his calling. The practical man stands ever ready to take up the work where the scientific man leaves it, and adapt it to the material wants and uses of daily life. — Louis Agassiz

Our scientists all the more occupy advanced positions in the development of world science. By the example of their successes in the field of atomic energy, our scientists and technicians have vividly shown how much the increased might of the Soviet state and the further growth of its international authority depends on their efforts and practical successes. — Vyacheslav Molotov

The relevant features of scientific practice often have mundane explanations which don't point to any deep metaphysical moral. (Thus it would simply be messy and pointless for the chemists to essay physical reductions, or for the biologists to offer number-free explanations. It's a weird kind of science-worship that views these practical considerations as clues to the nature of reality.) — David Papineau

I always tell writers that it's good to have an area of expertise. It's a really practical answer, I know, but know about science or about sports or about medicine, so you can work as a science writer or a sports writer. Don't just know about yourself. — Meghan Daum

Mathematics may, be briefly defined as the science of quantities, and is one of the most important of disciplining studies which engage the practical student. — Rufus Choate

Medicine is the science by which we learn the various states of the human body in health and when not in health, and the means by which health is likely to be lost and, when lost, is likely to be restored back to health. In other words, it is the art whereby health is conserved and the art whereby it is restored after being lost. While some divide medicine into a theoretical and a practical [applied] science, others may assume that it is only theoretical because they see it as a pure science. But, in truth, every science has both a theoretical and a practical side. — Avicenna

It is practical, but that doesn't mean it's right. — Pittacus Lore

For eighteen hundred years, though perchance I have no right to say it, the New Testament has been written; yet where is the legislator who has wisdom and practical talent enough to avail himself of the light which it sheds on the science of legislation? — Henry David Thoreau

We need to tap the resource of current and retiring science and math professionals that have both content mastery and the practical experience to serve as effective teachers. — Cathy McMorris Rodgers

As to the need of improvement there can be no question whilst the reign of Euclid continues. My own idea of a useful course is to begin with arithmetic, and then not Euclid but algebra. Next, not Euclid, but practical geometry, solid as well as plane; not demonstration, but to make acquaintance. Then not Euclid, but elementary vectors, conjoined with algebra, and applied to geometry. Addition first; then the scalar product. Elementary calculus should go on simultaneously, and come into vector algebraic geometry after a bit. Euclid might be an extra course for learned men, like Homer ... — Oliver Heaviside

The triumph of science has been mainly due to its practical utility, and there has been an attempt to divorce this aspect from that of theory, thus making science more and more a technique, and less and less a doctrine as to the nature of the world. The penetration of this point of view to philosophers is very recent. — Bertrand Russell

Individual curiosity, often working without practical ends in mind, has always been a driving force for innovation. — Frederick Seitz

Exact science and its practical movements are no checks on the greatest poet, but always his encouragement and support ... The sailor and traveller, the anatomist, chemist, astronomer, geologist, phrenologist, spiritualist, mathematician, historian and lexicographer are not poets, but they are the lawgivers of poets and their construction underlies the structure of every perfect poem. — Walt Whitman

The Science of Mind is intensely practical because it teaches us how to use the Mind Principle for definite purposes, such as helping those who are sick, impoverished, or unhappy. — Ernest Holmes

[To] mechanical progress there is apparently no end: for as in the past so in the future, each step in any direction will remove limits and bring in past barriers which have till then blocked the way in other directions; and so what for the time may appear to be a visible or practical limit will turn out to be but a bend in the road.
(Opening address to the Mechanical Science Section, Meeting of the British Association, Manchester.) — Osborne Reynolds

Finance is concerned with the relations between the values of securities and their risk, and with the behavior of those values. It aspires to be a practical, like physics or chemistry or electrical engineering. As John Maynard Keynes once remarked about economics, "If economists could manage to get themselves thought of as humble, competent people on a level with dentists, that would be splendid." Dentists rely on science, engineering, empirical knowledge, and heuristics, and there are no theorems in dentistry. Similarly, one would hope that nance would be concerned with laws rather than theorems, with behavior rather than assumptions. One doesn't seriously describe the behavior of a market with theorems. — Emanuel Derman

All science has one aim, namely, to find a theory of nature. We have theories of races and of functions, but scarcely yet a remote approach to an idea of creation. We are now so far from the road to truth, that religious teachers dispute and hate each other, and speculative men are esteemed unsound and frivolous. But to a sound judgment, the most abstract truth is the most practical. Whenever a true theory appears, it will be its own evidence. Its test is, that it will explain all phenomena. Now many are thought not only unexplained but inexplicable; as language, sleep, madness, dreams, beasts, sex. — Ralph Waldo Emerson

As in 1925, creationists are not battling for religion. They have been disowned by leading church men of all persuasions, for they debase religion even more than they misconstrue science. They are a motley collection to be sure, but their core of practical support lies with the evangelical right, and creationism is a mere stalking horse or subsidiary issue in a political program ... The enemy is not fundamentalism; it is intolerance. In this case, the intolerance is perverse since it masquerades under the 'liberal' rhetoric of 'equal time'. — Stephen Jay Gould

No delusion is greater than the notion that method and industry can make up for lack of mother-wit, either in science or in practical life. — Thomas Huxley

The object of science is knowledge; the objects of art are works. In art, truth is the means to an end; in science, it is the only end. Hence the practical arts are not to be classed among the sciences — William Whewell

A society whose experts would be priests, two thousand bankers and technicians ruling
over a Europe of one hundred and twenty million inhabitants where private life would be absolutely identified with
public life, where absolute obedience "of action, of thought, and of feeling" would be given to the high priest who
would reign over everything, such was Comte's Utopia, which announces what might be called the horizontal
religions of our times. It is true that it is Utopian because, convinced of the enlightening powers of science, Comte
forgot to provide a police force. Others will be more practical; the religion of humanity will be effectively founded
on the blood and suffering of humanity. — Albert Camus

In the collision between the remoteness and purity of the rainforest realms and the crassness of consumer culture, the difference is so extreme that for the most part there has been no authentic or practical method for this medicine system as traditionally practiced to integrate and adapt to the changing times. — Jonathon Miller Weisberger

Both for practical reasons and for mathematically verifiable moral reasons, authority and responsibility must be equal - else a balancing takes place as surely as current flows between points of unequal potential. To permit irresponsible authority is to sow disaster; to hold a man responsible for anything he does not control is to behave with blind idiocy. The unlimited democracies were unstable because their citizens were not responsible for the fashion in which they exerted their sovereign authority ... other than through the tragic logic of history ... No attempt was made to determine whether a voter was socially responsible to the extent of his literally unlimited authority. If he voted the impossible, the disastrous possible happened instead - and responsibility was then forced on him willy-nilly and destroyed both him and his foundationless temple. — Robert A. Heinlein

The life and soul of science is its practical application, and just as the great advances in mathematics have been made through the desire of discovering the solution of problems which were of a highly practical kind in mathematical science, so in physical science many of the greatest advances that have been made from the beginning of the world to the present time have been made in the earnest desire to turn the knowledge of the properties of matter to some purpose useful to mankind. — Lord Kelvin

The science of constructing a commonwealth, or renovating it, or reforming it, is, like every other experimental science, not to be taught a priori. Nor is it a short experience that can instruct us in that practical science, because the real effects of moral causes are not always immediate. — Edmund Burke

If they had kept quiet, and lain low for a time, things might have fizzled out as another unreal Wortstreist, blown up by a few ambitious authors of the party press. As it was, they decided to counter-attack the noisy, irrepressible outsiders--foreigners, to boot--and so forced a reluctant leadership to turn its full, slow, wrath against them; and against Bernstein too. For the most practical manifestation of revisionism was indiscipline and disobedience, a door opened to centrifugal forces of bourgeois influence. — John Peter Nettl

My father looked carelessly at the title page of my book, and said, "Ah! Cornelius Agrippa! My dear Victor, do not waste your time upon this; it is sad trash."
If, instead of this remark, my father had taken the pains to explain to me, that the principles of Agrippa had been entirely exploded, and that a modern system of science had been introduced, which possessed much greater powers than the ancient, because the powers of the latter were chimerical, while those of the former were real and practical; under such circumstances, I should certainly have thrown Agrippa aside, and, with my imagination warmed as it was, should probably have applied myself to the more rational theory of chemistry which has resulted from modern discoveries — Mary Shelley

What struck me most in England was the perception that only those works which have a practical tendency awake attention and command respect, while the purely scientific, which possess far greater merit are almost unknown. And yet the latter are the proper source from which the others flow. Practice alone can never lead to the discovery of a truth or a principle. In Germany it is quite the contrary. Here in the eyes of scientific men no value, or at least but a trifling one, is placed upon the practical results. The enrichment of science is alone considered worthy attention. — Justus Von Liebig

At my urgent request the Curie laboratory, in which radium was discovered a short time ago, was shown to me. The Curies themselves were away travelling. It was a cross between a stable and a potato-cellar, and, if I had not seen the worktable with the chemical apparatus, I would have thought it a practical joke.
(Wilhelm Ostwald on seeing the Curie's laboratory facilities.) — Wilhelm, Ostwald

As I see it the world is undoubtedly in need of a new religion, and that religion must be founded on humanist principles. When I say religion, I do not mean merely a theology involving belief in a supernatural god or gods; nor do I mean merely a system of ethics, however exalted; nor only scientific knowledge, however extensive; nor just a practical social morality, however admirable or efficient. I mean an organized system of ideas and emotions which relate man to his destiny, beyond and above the practical affairs of every day, transcending the present and the existing systems of law and social structure. The prerequisite today is that any such religion shall appeal potentially to all mankind; and that its intellectual and rational sides shall not be incompatible with scientific knowledge but on the contrary based on it. — Julian Huxley

Science has attained so much power that its practical limits begin to be apparent. Largely through science, billions of us live in one small world, densely packed and intercommunicating. But science cannot help us decide what to do with that world, or how to live. Science can make a nuclear reactor, but it cannot tell us not to build it. Science can make pesticide, but cannot tell us not to use it. — Michael Crichton

Every physical fact, every expression of nature, every feature of the earth, the work of any and all of those agents which make the face of the world what it is, and as we see it, is interesting and instructive. Until we get hold of a group of physical facts, we do not know what practical bearings they may have, though right-minded men know that they contain many precious jewels, which science, or the expert hand of philosophy will not fail top bring out, polished, and bright, and beautifully adapted to man's purposes. — Matthew Fontaine Maury

Long intervals frequently elapse between the discovery of new principles in science and their practical application ... Those intellectual qualifications, which give birth to new principles or to new methods, are of quite a different order from those which are necessary for their practical application. — Charles Babbage

But now science is the belief system that is hundreds of years old. And, like the medieval system before it, science is starting not to fit the world any more. Science has attained so much power that its practical limits begin to be apparent. Largely through science, billions of us live in one small world, densely packed and intercommunicating. But science cannot help us decide what to do with that world, or how to live. Science can make a nuclear reactor, but it cannot tell us not to build it. Science can make pesticide, but cannot tell us not to use it. And our world starts to seem polluted in fundamental ways
air, and water, and land
because of ungovernable science. — Michael Crichton

The Cosmos extends, for all practical purposes, forever. After a brief sedentary hiatus, we are resuming our ancient nomadic way of life. Our remote descendants, safely arrayed on many worlds throughout the Solar System and beyond, will be unified by their common heritage, by their regard for their home planet, and by the knowledge that, whatever other life may be, the only humans in all the Universe come from Earth. They will gaze up and strain to find the blue dot in their skies. They will love it no less for its obscurity and fragility. They will marvel at how vulnerable the repository of all our potential once was, how perilous our infancy, how humble our beginnings, how many rivers we had to cross before we found our way. — Carl Sagan

Intelligence is important in psychology for two reasons. First, it is one of the most scientifically developed corners of the subject, giving the student as complete a view as is possible anywhere of the way scientific method can be applied to psychological problems. Secondly, it is of immense practical importance, educationally, socially, and in regard to physiology and genetics. — Raymond Cattell

Science, at its core, is simply a method of practical logic that tests hypotheses against experience. Scientism, by contrast, is the worldview and value system that insists that the questions the scientific method can answer are the most important questions human beings can ask, and that the picture of the world yielded by science is a better approximation to reality than any other. — John Michael Greer

Pure science is a myth: Both mathematical theoreticians like Albert Einstein and practical crackpots like Henry Ford dealt with different aspects of the same world. — Edward Abbey

Engineering is not a science. Science studies particular events to find general laws. Engineering design makes use of the laws to solve particular practical problems. In this it is more closely related to art or craft. — Ove Arup

Engineering is the art or science of making practical. — Samuel Florman

The calculative exactness of practical life which the money economy has brought about corresponds to the ideal of natural science: to transform the world by mathematical formulas. Only money economy has filled the days of so many people with weighing, calculating, with numerical determinations, with a reduction of qualitative values to quantitative ones. — Georg Simmel

Around the lab I heard that publicity was measured in an absolute unit, the "kan". That unit was too large for ordinary application and a practical unit one one-thousandth of the size served in its place, the "millikan". — Luis W. Alvarez

The curious mind embraces science; the gifted and sensitive, the arts; the practical, business; the leftover becomes an economist — Nassim Nicholas Taleb

The scientist is a practical man and his are practical (i.e., practically attainable) aims. He does not seek the ultimate but the proximate. He does not speak of the last analysis but rather of the next approximation. His are not those beautiful structures so delicately designed that a single flaw may cause the collapse of the whole. The scientist builds slowly and with a gross but solid kind of masonry. If dissatisfied with any of his work, even if it be near the very foundations, he can replace that part without damage to the remainder. — Gilbert N. Lewis

Dilbert: It took weeks but I've calculated a new theory about the origin of the universe. According to my calculations it didn't start with a "Big Bang" at all-it was more of "Phhbwt" sound. You may be wondering about the practical applications of the "Little Phhbwt" theory. Dogbert: I was wondering when you'll go away. — Scott Adams

Insofar as we may at all claim that slavery has been abolished today, we owe its abolition to the practical consequences of science — Albert Einstein

Whoever, in the pursuit of science, seeks after immediate practical utility, may generally rest assured that he will seek in vain. — Hermann Von Helmholtz

I did an O-level in domestic science when I was at school, but on the day of the practical exam, it was a cookery nightmare. — Lesley Nicol

Surely to root politics out of art is a highly necessary undertaking: for the freedom of art, like that of science, depends entirely upon its objectivity and non-practical, non-partisan passion. — Wyndham Lewis

In some strata of Greek and Roman society the engineer was actually denigrated, higher esteem being accorded to poets, playwrights and sculptors. According to Plutarch, Archimedes was praised for refusing to contaminate his theoretical and mathematical science with practical applications, although under extreme pressure at the siege of Syracuse in Sicily he did design practical machinery. — Stephanie Dalley

I'm interested in using science to solve practical problems of our daily life. — Anonymous

The gray-haired growser, who proved to be a lawyer, had made it clear how much he loathed the people who were, in his view, attempting to undermine the American Constitution by imposing a state religion - or possibly it was "religion state by state," for his argument grew more confused with each Martini he sank. At any rate he was noisily predicting that the result would be world domination by the Communist bloc because they would wind up with a monopoly of practical science while his own people would be reduced to praying, sticking pins in chance-opened Bibles, and casting lots to decide whose eldest son should be sacrificed to stave off disaster. — John Brunner

Statistics is the most important science in the whole world: for upon it depends the practical application of every other science and of every art: the one science essential to all political and social administration, all education, all organization based on experience, for it only gives results of our experience. — Florence Nightingale

Those whose acquaintance with scientific research is derived chiefly from its practical results easily develop a completely false notion of the mentality of the men who, surrounded by a skeptical world, have shown the way to kindred spirits scattered wide through the world and through the centuries. Only one who has devoted his life to similar ends can have a vivid realization of what has inspired these men and given them the strength to remain true to their purpose in spite of countless failures. It is cosmic religious feeling that gives a man such strength. A contemporary has said, not unjustly, that in this materialistic age of ours the serious scientific workers are the only profoundly religious people. — Albert Einstein

ISTPs have a vested interest in practical and applied science, especially in the field of mechanics. — Isabel Briggs Myers

All scientific theories are provisional and may be changed, but ... on the whole, they are accepted from Washington to Moscow because of their practical success. Where religion has opposed the findings of science, it has almost always had to retreat. — Nevill Francis Mott

Reed College at that time offered perhaps the best calligraphy instruction in the country ... I decided to take a calligraphy class to learn how to do this ... It was beautiful, historical, artistically subtle in a way that science can't capture, and I found it fascinating. None of this had even a hope of any practical application in my life. But ten years later, when we were designing the first Macintosh computer, it all came back to me. — Steve Jobs

[Theology] may be defined, the doctrine or science of the truth which is according to godliness, and which God has revealed to man that he may know God and divine things, may believe on Him and may through faith perform to Him the acts of love, fear, honour, worship and obedience, and obtain blessedness from Him through union with Him, to the divine glory ... On this account, theology is not a theoretical science or doctrine, but a practical one, requiring the action of the whole man, according to all and each of it's parts
an action of the most transcendent description, answerable to the excellence of the object as far as the human capacity will permit. — James Arminius

What is the central core of the subject [computer science]? What is it that distinguishes it from the separate subjects with which it is related? What is the linking thread which gathers these disparate branches into a single discipline. My answer to these questions is simple -it is the art of programming a computer. It is the art of designing efficient and elegant methods of getting a computer to solve problems, theoretical or practical, small or large, simple or complex. It is the art of translating this design into an effective and accurate computer program. — Tony Hoare

The hypothesis of value realism is superfluous - a wheel that spins without being attached to anything. From a Darwinian perspective our impressions of value, if construed realistically, are completely groundless. And if that is true for our most basic responses, it is also true for the entire elaborate structure of value and morality that is built up from them by practical reflection and cultural development - just as scientific realism would be undermined if we abandoned a realistic interpretation of the perceptual experiences on which science is based. Even a system based on the maintenance of coherence or consistency among one's responses does not need the idea of mind-independent truth about value (as opposed to logic), — Thomas Nagel

Scientists have practical reasons for wishing that religion and science be kept separate. They can see nothing but trouble ... if they venture into the deeply divisive issue of religion - especially when their results tend to support a highly unpopular, atheistic conclusion. — Victor J. Stenger

Physics is like sex: sure, it may give some practical results, but that's not why we do it. — Richard Feynman

We must take the abiding spiritual values which inhere in the deep experiences of religion in all ages and give them new expression in terms of the framework which our new knowledge gives us. Science forces religion to deal with new ideas in the theoretical realm and new forces in the practical realm. — Harry Emerson Fosdick

Get back to work, he would tell himself sternly. There's a garuda to get airborne. — China Mieville

In the domain of true religion, mere book-learning has no right to enter. — Abhijit Naskar

Science is concerned with what is possible while engineering is concerned with choosing, from among the many possible ways, one that meets a number of often poorly stated economic and practical objectives. — Richard Hamming

The Black Book of Economic Development - The Clandestine Art and Practical Science of Building Local Economies" is a must-read for everyone in the industry who is seeking to make a positive impact on both his or her communities and the profession. — Don A. Holbrook
