Top 495 Theoretical Quotes & Sayings

Climate change is not a theoretical question for the people of the Caribbean.

It has long been my personal view that the separation of practical and theoretical work is artificial and injurious. Much of the practical work done in computing, both in software and in hardware design, is unsound and clumsy because the people who do it have not any clear understanding of the fundamental design principles of their work. Most of the abstract mathematical and theoretical work is sterile because it has no point of contact with real computing.

One advantage of exhibiting a hierarchy of systems in this way is that it gives us some idea of the present gaps in both theoretical and empirical knowledge. Adequate theoretical models extend up to about the fourth level, and not much beyond. Empirical knowledge is deficient at practically all levels.

The problem in D.C. is that everything is on paper, and it's theoretical.

I recognize that many physicists are smarter than I am-most of them theoretical physicists. A lot of smart people have gone into theoretical physics, therefore the field is extremely competitive. I console myself with the thought that although they may be smarter and may be deeper thinkers than I am, I have broader interests than they have.

I'm constantly meeting people that I hurt, you know? This is not - when I go and talk about these things, this is not a theoretical - it's not a theoretical apology. It's something that I live every day.

On the theoretical side, I was concerned with stochastic resonance.

First and foremost, note that Plato always wrote dialogues, and never attempted to produce a theoretical or scientific treatise. This is a big clue for me. From beginning to end, Plato was aware of the limits of theoretical and technical reasoning, and his dialogues are a massive exploration.

We have a theoretical concept of the Revolution which is a dictatorship of the exploited against the exploiters.

The most important tool of the theoretical physicist is his wastebasket.

Political parties are complicated coalitions and aren't excessively theoretical.

The fear of speculation, the ostensible rush from the theoretical to the practical, brings about the same shallowness in action that it does in knowledge. It is by studying a strictly theoretical philosophy that we become most acquainted with Ideas, and only Ideas provide action with vigour and ethical meaning.

I am now convinced that theoretical physics is actually philosophy.

Actually, I was more or less determined to be a theoretical physicist at the age of thirteen.

To become a theoretical physicist ... you need to have a passionate love affair with the universe.

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.

I want to study theoretical physics because it is one of the hardest things there is.

The job of a theoretical physicist is to make mistakes as fast as possible .

A theoretical grounding in agronomy must, therefore, include knowledge of biological laws.

The theoretical idea ... does not arise apart from and independent of experience; nor can it be derived from experience by a purely logical procedure. It is produced by a creative act. Once a theoretical idea has been acquired, one does well to hold fast to it until it leads to an untenable conclusion.

Atheism is a theoretical formulation of the discouraged life.

Most people don't have time to master the very mathematical details of theoretical physics.

Not infrequently ... the theoretical is a synonym of the stereotyped. For the 'theoretical' in chess is nothing more than that which can be found in the textbooks and to which players try to conform because they cannot think up anything better or equal, anything original.

Because of recent improvements in the accuracy of theoretical predictions based on large scale ab initio quantum mechanical calculations, meaningful comparisons between theoretical and experimental findings have become possible.

The umpire had comical news. The congregation had been theoretically spotted from the air by a theoretical enemy. They were all theoretically dead now. The theoretical corpses laughed and ate a hearty noontime meal.

There's always a tension in my world between the pragmatic and the practical and the theoretical. I have a very theoretical turn of mind, but I also like to test things in place.

There are no excuses for theoretical physicists not to perform and deliver.

The whole point of building theoretical systems is to explain what humans know by pre-theoretical experience. That is the starting point for any philosophy. That is the data it seeks to explain. If it fails to explain the data of experience, then it has failed the test. It has been falsified.

The Cabal is of two kinds, theoretical and practical, with the practical Cabala, which is engaged in the construction of talismans and amulets, we have nothing to do. The theoretical is divided into the lineal and dogmatic. The dogmatic is nothing more than the summary of the metaphysical doctrine taught by the Cabalist doctors. It is, in other words, the system of the Jewish philosophy.

Names and theoretical things don't occur to me. If they do, I'm not doing my real playing mode.

What if life after death is all based within memory: you die, and you don't ascend on a bed of clouds to Jesus, but your brain has a terrain that it can use to propel itself further. It's more of a theoretical afterlife. If that's true, all of these theoretical afterlives of people could potentially interact or network. That space seems way more powerful and exciting than reality. This potential boundlessness is more of what god is to me.

Even if we ignore the 'non-theoretical' knowledge which we acquire through experience (such as the knowledge of what something tastes like) and concentrate on theoretical knowledge, there is no good reason to think that physics can literally give the theory of everything. Here I want to be really pedantic. Although everything may be subject to physical law, not everything can be explained or described in physical terms. Physics has literally nothing to say about society, morality and the mind, for example - but of course these are parts of 'everything'.

Theoretical Computer Science is just as useless as everything we mathematicians do.

You can't be theoretical when you're building a musical.

Physics has entered a remarkable era. Ideas that were once the realm of science fiction are now entering our theoretical ? and maybe even experimental ? grasp. Brand-new theoretical discoveries about extra dimensions have irreversibly changed how particle physicists, astrophysicists, and cosmologists now think about the world. The sheer number and pace of discoveries tells us that we've most likely only scratched the surface of the wondrous possibilities that lie in store. Ideas have taken on a life of their own.

Theoretical approaches have their place and are, I suppose, essential but a theory must be tempered with reality.

Theoretical knowledge can not touch heart without Humility

Fiction and essays can create empathy for the theoretical stranger.

Nothing excites jaded Grandmasters more than a theoretical novelty

The consequences of a plethora of half-digested theoretical knowledge are deplorable.

A number of current theoretical explorations will turn out to be passing fancies...

Theoretical principals must sometimes give way for the sake of practical advantages.

In Fischer's hands, a slight theoretical advantage is as good a being a Queen ahead

Working in theoretical systems can take away the juice. It can also be very beautiful, but when you're trying to satisfy a theoretical principle rather than a sonic reality, then it can become dry.

Therefore psychologically we must keep all the theories in our heads, and every theoretical physicist who is any good knows six or seven different theoretical representations for exactly the same physics.

It is probably safe to say that all the changes of factual knowledge which have led to the relativity theory, resulting in a very great theoretical development, are completely trivial from any point of view except their relevance to the structure of a theoretical system.

My linguistics is pretty theoretical.

My background is in theoretical physics, and it's something very close to my heart.

Myths often do a lot of theoretical good, while they are still new.

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.

My older brother is a distinguished theoretical physicist, a fellow of the Royal Society.

There are theoretical reformers at all times, and all the world over, living on anticipation.

Life is not a theoretical problem to be solved in class.

I think our science is a marvelous tool. Of course it has its politics, its failings, its mistakes, like all other human endeavors, but I think the methodology of our science - using it to postulate and to use the proper approach of creating falsifiable hypotheses and then testing them to see if they ring true, and then progressing by finding the anomalies to our theoretical structure, and then improving our theoretical structure to take care and test the anomalies - is the way to go, because that helps us discover what the universe.is all about and our relationship to it.

The test is can you do something, rather than have a theoretical argument - can you make a difference?

All theoretical chemistry is really physics; and all theoretical chemists know it.

Musically, swing pretty much dominated in the '30s. And into the late '30s, swing is beginning to change over to bebop in the early '40s, which is exactly when this new science of theoretical physics, particularly theoretical atomic physics, was really coming to the fore.

I feel that I've had enough theoretical speculation to last me a lifetime.

A second possible approach to general systems theory is through the arrangement of theoretical systems and constructs in a hierarchy of complexity, roughly corresponding to the complexity of the "individuals" of the various empirical fields... leading towards a "system of systems." [...] I suggest below a possible arrangement of "levels" of theoretical discourse...(vi) [...] the "animal" level, characterized by increased mobility, teleological behavior and self-awareness...

I am a phenomenologist - I work on developing theoretical models that are constrained by observations.
