Quotes About Theoretical

The basic theory in twistor theory is not to add extra dimensions.

As you say, the way string theory requires all these extra dimensions and this comes from certain consistency requirements about how string should behave and so on.

The funny thing is, I sometimes get the impression that some people outside of the field think that there's some element of security that we have in working on a theory that hasn't made any predictions that can be proven false. In a sense, we're working on something unfalsifiable.

All the evidence, experimental and even a little theoretical, seems to indicate that it is the energy content which is involved in gravitation, and therefore, since matter and antimatter both represent positive energies, gravitation makes no distinction.

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

There is no theoretical study of motherhood. You know, before I became a mother, I did play a mother, but I was like - I was more thinking of my own mother. I was doing my mother.

The methods of theoretical physics should be applicable to all those branches of thought in which the essential features are expressible with numbers.

Physics is often stranger than science fiction, and I think science fiction takes its cues from physics: higher dimensions, wormholes, the warping of space and time, stuff like that.

Paul of Tarsus, for instance. Putting aside the little problem with all the people he had killed, he was annoying, sexist, stuffy, and theoretical. He was not a great storyteller like the Gospel writers. He often got preachy, and his message was frequently about trying to be more stoic, with dogmatic Shape up and Shame on you talks.

He described the securities—called Abacus—to a girlfriend: I had some input into the creation of this product (which by the way is a product of pure intellectual masturbation, the type of thing which you invent telling yourself 'Well, what if we created a "thing," which has no purpose, which is absolutely conceptual and highly theoretical and which nobody knows how to price?').15

a keelboat's theoretical hull speed—the top speed it can attain without surfing or planing—is dictated by a simple formula: the square root of the waterline length multiplied by 1.34.

Theoretical inquiry involves a search for regularities. It involves abstraction from the complexity of a field setting, followed by the positing of theoretical variables that underlie observed complexities.

Godwin and Shepard (1979) pointed out a decade ago that policy scientists were doing the equivalent of "Forcing Squares, Triangles and Ellipses into a Circular Paradigm" by using the commons-dilemma model without serious attention to whether or not the variables in the empirical world conformed to the theoretical model.

F]or a social theorist ignorance is more excusable than vagueness. Other investigators can easily show I am wrong if I am sufficiently precise. They will have much more difficulty showing by investigation what, precisely, I mean if I am vague. I hope not to be forced to weasel out with 'But I didn't really mean that.' Social theorists should prefer to be wrong rather than misunderstood. Being misunderstood shows sloppy theoretical work.

the progress of science depends much less upon either theoretical considerations or systematic investigation than is commonly believed, but rather on the transmittal of reliable information, gained by chance or insight, from one set of men to their successors.

To a theoretical physicist, there is no greater joy than to see that this curious activity we call calculation - the depositing of ink on paper, followed by throwing away the paper and depositing new ink on more paper - can actually tell us something about reality.

Thus, in general, in the first instance, the direction of interest in empirical fact will be canalised by the logical structure of the theoretical system.

Leaving England was a painful decision, and we still have some regrets about it. However, at that time, the research environment for theoretical chemistry was clearly better in the U.S.

Mediocre theoretical physicists make no progress. They spend all their time understanding other people's progress.

Whether you can go back in time is held in the grip of the law of quantum gravity. We are several decades away from a definitive understanding, 20 or 30 years, but it could be sooner than that.

an expressive phrase coined by a Princeton mathematician of the last century: "Wormholes in space.

You may place considerable confidence in Mr. Holmes, sir," said the police agent loftily. "He has his own little methods, which are, if he won't mind my saying so, just a little too theoretical and fantastic, but he has the makings of a detective in him.

It is a fact that we have always behaved as if we knew all this; but, for the most part, our theoretical concepts have neglected to attach the same importance to the economic line of approach as they have to the dynamic and topographical ones.

Turing knew of Babbage's work, and the universal Turing machine can be seen as a reincarnation of Difference Engine No. 2. In fact, Turing had gone much further, and provided computing with a solid theoretical basis
