Top 1200 Scientific Theory Quotes & Sayings - Page 8

Very much, string theory is simply a work in progress. What we are inching toward every day are predictions that within the realm of current technology we hope to test. It's not like we're working on a theory that is permanently beyond experiment. That would be philosophy.

Classic economic theory, based as it is on an inadequate theory of human motivation, could be revolutionized by accepting the reality of higher human needs, including the impulse to self actualization and the love for the highest values.

Evolution is a theory, and it's a theory that you can test. We've tested evolution in many ways. You can't present good evidence that says evolution is not a fact.

For example, there are numbers of chemists who occupy themselves exclusively with the study of dyestuffs. They discover facts that are useful to scientific chemistry; but they do not rank as genuine scientific men. The genuine scientific chemist cares just as much to learn about erbium-the extreme rarity of which renders it commercially unimportant-as he does about iron. He is more eager to learn about erbium if the knowledge of it would do more to complete his conception of the Periodic Law, which expresses the mutual relations of the elements.

Relativity was a highly technical new theory that gave new meanings to familiar concepts and even to the nature of the theory itself. The general public looked upon relativity as indicative of the seemingly incomprehensible modern era, educated scientists despaired of ever understanding what Einstein had done, and political ideologues used the new theory to exploit public fears and anxieties-all of which opened a rift between science and the broader culture that continues to expand today.

A US Department of Education; implementation of a scientific materialist philosophy; studies, being cleansed of religious, patriotic and other features of the bourgeois ideology; students taught on the basis of Marxian dialectical materialism, internationalism and general ethics of a new socialist society; present obsolete methods of teaching will be superseded by a scientific pedagogy. The whole basis and organization of capitalist science will be revolutionized. Science will become materialistic, hence truly scientific. God will be banished from the laboratories as well as from the schools.

The oldest theory of art belongs to the Greeks, who regarded art as an imitation (mimesis) of reality. The strength of that theory is that it explains the way in which art takes its materials from real life.

[Donald] Trump and all the Republicans believe in the theory of trickle down economics which is a theory discredited even by the author himself David Stockton. The theory suggests that if we take care of the people at the top, if we cut taxes for the wealthy, if we make sure they are doing really well, then the investments that they make in the economy and the jobs that will create, will make everything grow and it will have a trickle down effect on the rest of us.

Debating, doubting, or rejecting the basic scientific facts about climate change in the face of the overwhelming evidence and overwhelming scientific opinion will not change those facts.

Schizophrenia --its nature, etiology, and the kind of therapy to use for it--remains one of the most puzzling of the mental illnesses. The theory of schizophrenia presented here is based on communications analysis, and specifically on the Theory of Logical Types. From this theory and from observations of schizophrenic patients is derived a description, and the necessary conditions for, a situation called the "double bind"--a situation in which no matter what a person does, he "can't win." It is hypothesized that a person caught in the double bind may develop schizophrenic symptoms

We shall see that the mathematical treatment of the subject [of electricity] has been greatly developed by writers who express themselves in terms of the 'Two Fluids' theory. Their results, however, have been deduced entirely from data which can be proved by experiment, and which must therefore be true, whether we adopt the theory of two fluids or not. The experimental verification of the mathematical results therefore is no evidence for or against the peculiar doctrines of this theory.

We may take it to be the accepted idea that the Mosaic books were not handed down to us for our instruction in scientific knowledge, and that it is our duty to ground our scientific beliefs upon observation and inference, unmixed with considerations of a different order.

I did the first proofreading of 'A Brief History of Time,' and when it came to writing my memoir, I consulted many scientific friends so that, contrary to what many critics supposed and were churlish enough to voice, I did actually write the scientific sections myself.

Thought and theory must precede all action, that moves to salutary purposes. Yet action is nobler in itself than either thought or theory.

Thus the theory of description matters most. It is the theory of the word for those For whom the word is the making of the world, The buzzing world and lisping firmament.

How is it that, in the face of overwhelming scientific evidence, there are still some who would deny the dangers of climate change? Not surprisingly, the loudest voices are not scientific, and it is remarkable how many economists, lawyers, journalists and politicians set themselves up as experts on the science.

Pytheos made a mistake by not observing that the arts are each composed of two things, the actual work and the theory of it. One of these, the doing of the work, is proper to men trained in the individual subject, while the other the theory is common to all scholars.

It must be conceded that a theory has an important advantage if its basic concepts and fundamental hypotheses are 'close to experience,' and greater confidence in such a theory is certainly justified. There is less danger of going completely astray, particularly since it takes so much less time and effort to disprove such theories by experience. Yet more and more, as the depth of our knowledge increases, we must give up this advantage in our quest for logical simplicity in the foundations of physical theory.

[About John Evershed] There is much in our medallist's career which is a reminder of the scientific life of Sir William Huggins. They come from the same English neighbourhood and began as amateurs of the best kind. They both possess the same kind of scientific aptitude.

I do not believe that a moral philosophy can ever be founded on a scientific basis. … The valuation of life and all its nobler expressions can only come out of the soul’s yearning toward its own destiny. Every attempt to reduce ethics to scientific formulas must fail. Of that I am perfectly convinced.

The belief that politics can be scientific must inevitably produce tyrannies. Politics cannot be a science, because in politics theory and practice cannot be separated, and the sciences depend upon their separation. Empirical politics must be kept in bounds by democratic institutions, which leave it up to the subjects of the experiment to say whether it shall be tried, and to stop it if they dislike it, because, in politics, there is a distinction, unknown to science, between Truth and Justice.

When the theory of evolution destroyed the picture of God as the supreme Creator, confidence in God as the all-powerful Father of man fell with it, although many were able to combine a belief in God with the acceptance of the Darwinian theory.

Well, gauge theory is very fundamental to our understanding of physical forces these days. But they are also dependent on a mathematical idea, which has been around for longer than gauge theory has.

In order to achieve a true understanding of string theory, some new idea will be required, and most likely, some break with the concepts on which we've traditionally based physical theory.

Every great master will find it useful to have his own theory on the openings, which only he himself knows, a theory which is closely linked with plans for the middle game.

Natural Selection is not Evolution. Yet, ever since the two words have been in common use, the theory of Natural Selection has been employed as a convenient abbreviation for the theory of Evolution by means of Natural Selection, put forward by Darwin and Wallace. This has had the unfortunate consequence that the theory of Natural Selection itself has scarcely ever, if ever, received separate consideration.

The care of a house, the conduct of a home, the management of children, the instruction and government of servants, are as deserving of scientific treatment and scientific professors and lectureships as are the care of farms, the management of manure and crops, and the raising and care of stock.

We simulated the predator with livestock and the perennial grassland returned. Just put the whole back, and there it was. You'll find the scientific method never discovers anything. Observant, creative people make discoveries. But the scientific method protects us from cranks like me.

From Roger Bacon, the 13th century Franciscan who pioneered the scientific method, to George Lemaitre, the 20th century Belgian priest who first developed a mathematical foundation for the 'Big Bang,' people of faith have played a key role in advancing scientific understanding.

Genetically modified organism (GMO) foods are feared and hated by environmentalists and the public alike. Yet the scientific assessment of GMOs is remarkably different. Every major scientific evaluation of GMO technology has concluded that GMOs are safe for human consumption and are a benefit to the environment.

Our rockets can find Halley's comet, and fly to Venus with amazing accuracy, but side by side with these scientific and technical triumphs is an obvious lack of efficiency in using scientific achievements for economic needs. Many Soviet household appliances are of poor quality.

I cannot seriously believe in it [quantum theory] because the theory cannot be reconciled with the idea that physics should represent a reality in time and space, free from spooky actions at a distance [spukhafte Fernwirkungen].

One of the strangest features of string theory is that it requires more than the three spatial dimensions that we see directly in the world around us. That sounds like science fiction, but it is an indisputable outcome of the mathematics of string theory.

A theory can be proved by experiment; but no path leads from experiment to the birth of a theory.

I don't think that design needs theory, but I think designers need theory.

According to the 2000 'Report of the U.N. Scientific Committee on the Effects of Atomic Radiation,' the long-lasting effects of nuclear testing can be qualified in simple scientific terms: 'Radiation exposure can damage living cells, causing death in some of them and modifying others.'

But though the professed aim of all scientific work is to unravel the secrets of nature, it has another effect, not less valuable, on the mind of the worker. It leaves him in possession of methods which nothing but scientific work could have led him to invent.

His [Henry Cavendish's] Theory of the Universe seems to have been, that it consisted solely of a multitude of objects which could be weighed, numbered, and measured; and the vocation to which he considered himself called was, to weigh, number and measure as many of those objects as his allotted three-score years and ten would permit. This conviction biased all his doings, alike his great scientific enterprises, and the petty details of his daily life.

Nearly everyone I know seems to have a well-developed theory as to why this country is past redemption, or almost, and every theory seems almost right.

Capitalism has been fully restored in Yugoslavia, as is well-known, but this capitalism knows how to disguise. Yugoslavia portrays itself as a socialist state, but of a special kind, as the world has never seen it before! The Titoites even boast that their state has nothing in common with the first socialist state which emerged from the socialist October Revolution and which was founded by Lenin and Stalin on the basis of the scientific theory of Marx and Engels.

Those who cavalierly reject the Theory of Evolution, as not adequately supported by facts, seem quite to forget that their own theory it supported by no facts at all.

On the question of the world as a whole, science founders. For scientific knowledge the world lies in fragments, the more so the more precise our scientific knowledge becomes.

In the case of some people, not even if we had the most accurate scientific knowledge, would it be easy to persuade them were we to address them through the medium of that knowledge; for a scientific discourse, it is the privilege of education to appreciate, and it is impossible that this should extend to the multitude.

The traditional boundaries between various fields of science are rapidly disappearing and what is more important science does not know any national borders. The scientists of the world are forming an invisible network with a very free flow of scientific information - a freedom accepted by the countries of the world irrespective of political systems or religions. ... Great care must be taken that the scientific network is utilized only for scientific purposes - if it gets involved in political questions it loses its special status and utility as a nonpolitical force for development.

The general point that a political theory is, among other things, a partisan intervention, is well taken. So question about the actual political implication of a theory cannot be excluded as, in principle, irrelevant.

I don't think theory adds to criticism. (Methodology does, for better or worse.) Theory's function is to make criticism self-conscious, maybe even a little sheepish, about its ex cathedra pronouncements.

If facts conflict with a theory, either the theory must be changed or the facts.

Government is founded not on force, as was the theory of Hobbes; nor on compact, as was the theory of Locke and of the revolution of 1688; nor on property, as was the assertion of Harrington. It springs from the necessities of our nature, and has an everlasting foundation in the unchangeable will of God.

In Einstein's theory of relativity the observer is a man who sets out in quest of truth armed with a measuring-rod. In quantum theory he sets out with a sieve.

The best theory comes from string theory, which states that dark matter is nothing but a higher vibration of the string. We are, in some sense, the lowest octave of a vibrating string.

It presents a really compelling case against the whole theory of anthropogenic global warming. From my point of view, it is a theory that has completely corrupted public policy making in most of the developed world. It confronts all the dubious claims that the warmists have put out there.

By the 'mud-sill' theory it is assumed that labor and education are incompatible; and any practical combination of them impossible. According to that theory, a blind horse upon a tread-mill, is a perfect illustration of what a laborer should be -- all the better for being blind, that he could not tread out of place, or kick understandingly. According to that theory, the education of laborers, is not only useless, but pernicious, and dangerous. In fact, it is, in some sort, deemed a misfortune that laborers should have heads at all.

Both for my wife and myself, the personal friendships that have grown out of scientific contacts with colleagues from many different countries have been an important part of our lives, and the travels we have made together in connection with the world-wide scientific co-operation have given us rich treasures of experiences.

If the evidence says you're wrong, you don't have the right theory. You change the theory, not the evidence.

For [Richard] Feynman, the essence of the scientific imagination was a powerful and almost painful rule. What scientists create must match reality. It must match what is already known. Scientific creativity is imagination in a straitjacket.

There is no such thing as absolute truth and absolute falsehood. The scientific mind should never recognise the perfect truth or the perfect falsehood of any supposed theory or observation. It should carefully weigh the chances of truth and error and grade each in its proper position along the line joining absolute truth and absolute error.

I have always thought it a great privilege to have as my colleague in the Palit Chair of Chemistry such a distinguished pioneer in scientific research and education in Bengal as Sir Prafulla Ray. It has been invariably my experience that I could count on his cooperation and sympathy in every matter concerning my scientific work.

Scientific theories never dictate human values, but they can often cast new light on ethical issues. From a sexual selection viewpoint, moral philosophy and political theory have mostly been attempts to shift male human sexual competitiveness from physical violence to the peaceful accumulation of wealth and status. The rights to life, liberty, and property are cultural inventions that function, in part, to keep males from killing and stealing from one another while they compete to attract sexual partners.

In sum: banking theory and practice, as immobilizing and fixating forces, fail to acknowledge men and women as historical beings; problem-posing theory and practice take the people's historicity as their starting point.

So when you ask me how string theory might be tested, I can tell you what's likely to happen at accelerators or some parts of the theory that are likely to be tested.
