CBS's Major Garrett writes in 'National Journal' about a new version of the 'stray voltage' theory of communication in which the president purposefully overstates his case knowing that it will create controversy.

I suspect that pleasure is mainly used to turn off parts of the brain so you can keep fresh the memories of things you're trying to learn. It protects the short-term memory buffers. That's one theory of pleasure.

Every theory presented as a scientific concept is just that; it's a theory that tries to explain more about the world than previous theories have done. It is open to being challenged and to being proven incorrect.

Entropy theory is indeed a first attempt to deal with global form; but it has not been dealing with structure. All it says is that a large sum of elements may have properties not found in a smaller sample of them.

Because the theory of quantum mechanics could explain all of chemistry and the various properties of substances, it was a tremendous success. But still there was the problem of the interaction of light and matter.

The struggle for existence holds as much in the intellectual as in the physical world. A theory is a species of thinking, and its right to exist is coextensive with its power of resisting extinction by its rivals.

Why has not anyone seen that fossils alone gave birth to a theory about the formation of the earth, that without them, no one would have ever dreamed that there were successive epochs in the formation of the globe.

A potentially useful property of forecasts based on cointegration is that when extended some way ahead, the forecasts of the two series will form a constant ratio, as is expected by some asymptotic economic theory.

It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some say that the only thing that quantum theory has going for it is that it is unquestionably correct.

We could solve all our problems if only we were the efficient, rational human beings of standard economic theory and had politicians willing to think in the long-term interest of their people rather than their own.

Ideas matter in New York. I am certain that more conversations in New York are about ideas than anywhere else. Not just vague theories, but ideas that New Yorkers have the will, and the clout, to do something about.

Some people would claim that things like love, joy and beauty belong to a different category from science and can't be described in scientific terms, but I think they can now be explained by the theory of evolution.

The first rule is that you can't really know anything if you just remember isolated facts and try and bang 'em back. If the facts don't hang together on a latticework of theory, you don't have them in a usable form.

If I take the theory as we have it now, literally, I would conclude that extra dimensions really exist. They're part of nature. We don't really know how big they are yet, but we hope to explore that in various ways.

In some ways, risk-taking is the ultimate act of self-indulgence, an obscene insult to the preciousness of life. And yet, how can one dismiss something that persists despite every reasonable theory that it shouldn't?

Since the Reagan era, Republicans have prescribed cuts for rich people and corporations as a cure-all. But every time they put their theory into practice, the rich just get richer, and everyone else gets left behind.

The final outcome cannot be known, either to the originator of a new theory, or to his colleagues and critics, who are bent on falsifying it. Thus, the scientific innovator may feel all the more lonely and uncertain.

There's a statistical theory that if you gave a million monkeys typewriters and set them to work, they'd eventually come up with the complete works of Shakespeare. Thanks to the Internet, we now know this isn't true.

We humans have a tendency to see ourselves as completely different from other animals, and the way in which large segments of the public continue to reject the theory of evolution is just one symptom of that malaise.

From this bestial view that the human mind consists of only sense certainty, pleasure and pain, Locke developed an equally bestial theory of the nation. Man originally existed in a State of Nature of complete liberty.

America's popular heroes have seldom been its great thinkers, and even less its scientists. The success of TV's 'Big Bang Theory,' which seems to give the lie to this claim, is more the exception that proves the rule.

I believe in education, but I think the balance has to be right between theory and practical experience. I think from secondary school onwards it should be more about preparing you for life and work in the real world.

To put it bluntly, there isn't one economic theory that can single-handedly explain Singapore's success; its economy combines extreme features of capitalism and socialism. All theories are partial; reality is complex.

General relativity is the cornerstone of cosmology and astrophysics. It has also provided the conceptual basis for string theory and other attempts to unify all the forces of nature in terms of geometrical structures.

I think literary theory has not been terribly good for English studies in a while. It's not that theory isn't interesting, but it isn't about books, or the idiosyncrasies and complexities of putting language together.

Land: A part of the earth's surface, considered as property. The theory that land is property subject to private ownership and control is the foundation of modern society, and is eminently worthy of the superstructure.

If you sing beautifully about nothing, no one will listen. If you sing badly about great stuff, no one will listen. Ideas are everywhere, but my theory is that a writer doesn't just think of an idea: they perform them.

I had some hesitations about philosophy because, if you worked out a philosophical theory, it was hard to know whether you were going to be able to prove it or whether other theories had just as good a claim on belief.

It's easy to get next to music theory, especially between your peers and music classes and so forth. You just pay attention. I had a good ear, so I realized that printed music was just about reminding you what to play.

So long as we use a certain language, all questions that we can ask will have to be formulated in it and will thereby confirm the theory of the universe which is implied in the vocabulary and structure of the language.

We know from chaos theory that even if you had a perfect model of the world, you'd need infinite precision in order to predict future events. With sociopolitical or economic phenomena, we don't have anything like that.

But we did conclude that Ray had actually killed Dr. King pursuant to his theory that he was going to be able to get hold of that money. He had learned of this offer through his ties in the Missouri State Penitentiary.

I have a theory that the best ads come from personal experience. Some of the good ones I have done have really come out of the real experience of my life, and somehow this has come over as true and valid and persuasive.

I became interested in this question of whether you can build wormholes for interstellar travel. I realized that if you had a wormhole, the theory of general relativity by itself would permit you to go backward in time.

In its first 30 years of existence, up to the mid 1970s, the practical applications of game theory were very limited, probably as a result of excessive preoccupation by game theorists with cooperative solution concepts.

Now I'm no biologist, but it seems to make a lot of sense that slow lives, as well as being enjoyable, are long lives. One only has to think of the example of the tortoise for proof of this theory from the animal world.

Positivism eliminates any kind of natural law principle - for example, that there are economic laws which can be transgressed only at your peril. With positivism, there is a tendency to leap into ad hoc economic theory.

My roommate at Yale University introduced me to the auteur theory of filmmaking. I soon became a big fan of the works of John Ford, Kenji Mizoguchi, Ernst Lubitsch, and Stan Brakhage. I then decided to make my own films!

My theory about why Hemingway killed himself is that he heard his own voice; that he reached the point where he couldn't write without feeling he was repeating himself. That's the worst thing that can happen to a writer.

The fundamental proposition of the apriorist theory is that knowledge is made up of two sorts of elements, which cannot be reduced into one another, and which are like two distinct layers superimposed one upon the other.

The intersection of political analysis and Internet theory is a busy crossroad of cliche, where familiar rhetorical vehicles - decentralized authority, emergent leadership, empowered grass roots - create a ceaseless buzz.

I developed a theory that, in many ways, the early 'Andy Griffith' episodes especially were an awful lot like a Capra movie. They were a lot like 'Mr. Deeds' or a lot like 'It's a Wonderful Life' in tone and presentation.

There's something about 'Strictly Come Dancing.' Everywhere I go, people wish me good luck; cabbies toot their horns. It's lovely. I have a theory: in straitened times, there's nothing like a bit of unapologetic escapism.

I wanted Season 2 of Luke Cage to be Ice Cube's 'Death Certificate,' or Fugees' 'The Score,' or Public Enemy's 'It Takes a Nation of Millions to Hold Us Back,' or my favorite, 'The Low End Theory' by A Tribe Called Quest.

I was diagnosed with ADHD twice. I didn't believe the first doctor who told me, and I had a whole theory that ADHD was just something they invented to make you pay for medicine, but then the second doctor told me I had it.

The three parts of the theory are analytical ability, the ability to analyze things to judge, to criticize. Creative, the ability to create, to invent and discover and practical, the ability to apply and use what you know.

The General Theory was not truly revolutionary at all but merely old and oft-refuted mercantilist and inflationist fallacies dressed up in shiny new garb, replete with newly constructed and largely incomprehensible jargon.

My theory of change is that there are already millions of people working day in and day out on the ground to deliver on promises on global change. We need to strengthen those institutions and help those people in the field.

Wyndham Lewis is basically a pessimist, thinking of human beings as doomed animals or determinist machines. His theory of satire is based on this view, and he finds plenty of evidence to support it in contemporary practice.

I'm not into politics but I am committed to a cause: ensuring design technology and engineering stays on the U.K. curriculum, alongside science and maths - grounding abstract theory, merging the practical with the academic.
