In mathematics, defined and undefined are used to explain whether or not expressions have meaningful, sensible output. These are also known as "well-behaved" and respectively "ill-behaved". The following algebraic expressions are undefined: (see division by zero) 00 (however, it is often convenient to define the value of this expression to be 1, e.g. in combinatorics, in the context of power series, and in set theory) (however, in probability and measure theory ...

The notion of definability treated in this article has been chosen primarily for definiteness, not on the grounds that it's more useful or interesting than other notions. Here we treat a few others: Definable number - Definability in other languages or structures. The language of arithmetic has symbols for 0, 1, the successor operation, addition, and multiplication, intended to be interpreted in the usual way over the natural numbers. Since no variables of this language range over the reals, we can ...

The anxiety disorder pure obsessional OCD, commonly called Pure O, is a form of obsessive-compulsive disorder. It is distinct from traditional OCD in that it features no outward manifestations; instead, both the anxiety-inducing obsessions and relief-seeking compulsions of OCD take place in the mind. With standard OCD, the compulsions manifest as physical rituals: excessive hand-washing, checking, cleaning. With Pure O, the compulsions manifest as unseen mental rituals, but they are compulsions nonetheless, which is why th ...

Bart is crushed to discover that Milhouse had held a birthday party the previous Saturday, but he had not been invited. Milhouse seems unwilling to talk to Bart and avoids him for the rest of the day. Meanwhile, at the power plant, as Homer eats jelly donuts, one of them splatters onto a dial nearing the red zone. The plant is on the verge of a nuclear meltdown, and Homer seems to be the only person who can stop it. He has no s ...

The definable numbers form a field containing all the familiar real numbers such as 0, 1, π, e, et cetera. In particular, it contains all the numbers named in the mathematical constants article, and all algebraic numbers (and therefore all rational numbers). However, most real numbers are not definable: the set of all definable numbers is countably infinite (because the set of all logical formulas is) while the set of real numbers is uncountably infinite (see Cantor's diagonal argument). As a result, most real numbers have no description (in the same sense o ...

The purpose of these data structures is to translate the physical representation of codes into a logical representation. The physical representation is "compressed" due to hardware limitations. The number of memory spaces, for instance, is limited, so a memory space (register, word in main memory, etc.) might take on multiple values over the course of its life. The physical location of the data is not interesting at to the compiler at this stage. However, the compiler needs to track the values, not the locations. Consequently, making ...

In his monumental dictionary, Samuel Johnson states that the original meaning of wit is "the powers of the mind; the mental faculties; the intellects"; he also defines wit as "quickness of fancy", among the nine definitions. In Webster's Dictionary, wit is subtly defined as "the association of ideas in a manner natural, but unusual and striking, so as to produce surprise joined with pleasure". The American television series The Simpsons defined wit, in a February 4, 1996 episode as "nothing more than an incisive observation, humorously phrased and ...

It is difficult to define understanding. If we use the term concept as above, the question then arises as to what is a concept? Is it an abstract thing? Is it a brain pattern or a rule? Whatever definition is proposed, we can still ask how it is that we understand the thing that is featured in the definition: we can never satisfactorily define a concept, still less use it to explain understanding. It is more convenient to use an operational or behavioural definition, we can say that somebody who reacts appropriately t ...

Like Java, Ajile provides a Package directive for defining namespaces. Using the Package directive is trivial as demonstrated by the following example: Package ("com.iskitz.ajile.examples"); com.iskitz.ajile.examples.PackageExample = function() { alert("This is the PackageExample!"); }; In the above example a com.iskitz.ajile.examples namespace is created and a PackageExample module is added to it. A reversed domain name is used as ...

Breakcore is a loosely defined electronic music style that brings together elements of jungle, hardcore techno and IDM into a breakbeat-oriented sound that encourages speed, complexity, impact and maximum sonic density. Similar to Punk or Jazz music; Breakcore does not adhere to a predefined set of stylistic 'rules', instead following a looser set of musical ideals. The very nature of breakcore is anti-establishment, often using production techniques or sounds to intentionally alienate the non-breakcore listener. Musically, breakcore is centered around the deconstruction and creative reassembly of common breakb ...

While knowledge is a central part of daily life, the actual definition of knowledge is of great interest to philosophers, social scientists, and historians. Knowledge, according to most thinkers, must follow three defining criteria. It must be justified, true, and believed. Meeting these qualifications may be difficult or impossible. It is also common to weigh knowledge in how it can be applied or used. In this sense, knowledge consists of information augmented by intentionality (or direction). This model aligns with the DI ...

In the first edition (June 1979) of The Plantsman (a specialist journal published by the Royal Horticultural Society), Sandra Raphael (then a senior editor in the Dictionary Department of the Oxford University Press) contributed a short article on the history and meaning of the word. Her first example came from an issue of the Gardeners' Chronicle of 1881, when it seemed to mean "A nurseryman, a florist" (in the early sense of "florist" as a grower and breeder of flowers, rather than the more recent meaning of someone wh ...

COBOL as defined in the original specification, possessed excellent self-documenting capabilities, good file handling methods, and exceptionally good data typing for the time, owing to its use of the PICTURE clause for detailed field specification. However, until the 1985 Standard, it had serious flaws by modern standards for programming language definition, notably of support for local variables, recursion, dynamic memory allocation, and structured programming. Its perceived lack of explicit support for object-oriented programming is unders ...
