I've made the most important discovery of my life. It's only in the mysterious **equation** of love that any logical reasons can be found.

Man is naturally self-centered and he is inclined to regard expediency as the supreme standard for what is right and wrong. However, we must not convert an inclination into an axiom that just as man's perceptions cannot operate outside time and space, so his motivations cannot operate outside expediency; that man can never transcend his own self. The most fatal trap into which thinking may fall is the **equation** of existence and expediency.

— Ch. 5 (Who Is Man? (1965))

A great deal of the thinking [in Organizational Development] has been influenced by cybernetics and information theory, though this has been used as much to extend the scope of closed-system as to improve the sophistication of open system formulations. It was von Bertalanffy (1950) who, in terms of the general transport **equation** which he introduced, first fully disclosed the importance of openness or closedness to the environment as a means of distinguishing living organisms from inanimate objects.

Von Neumann languages do not have useful properties for reasoning about programs. Axiomatic and denotational semantics are precise tools for describing and understanding conventional programs, but they only talk about them and cannot alter their ungainly properties. Unlike von Neumann languages, the language of ordinary algebra is suitable both for stating its laws and for transforming an **equation** into its solution, all within the "language."

...where Nietzsche’s response to the **equation** of socialism and morality was to question the value of morality, at least as it had been customarily understood, economists like Mises and Hayek pursued a different path, one Nietzsche would never have dared to take: they made the market the very expression of morality.

One day he was explaining a relation to me; then he suddenly turned round and said, "Sir, an **equation** has no meaning for me unless it expresses a thought of GOD."

The factors left out of the Ricardian **equation** are falling wages and idle capacity.

Today's scientists have substituted mathematics for experiments, and they wander off through **equation** after **equation**, and eventually build a structure which has no relation to reality.

Instead, we try to apply Aesop 's 2,600-year-old **equation** to opportunities in which we have reasonable confidence as to how many birds are in the bush and when they will emerge (a formulation that my grandsons would probably update to "A girl in a convertible is worth five in the phonebook.").

We are, as I have said, one **equation** short.

The critical element in this **equation** is developing inclusiveness that envelopes all these competing priorities (of the different ethnic groups) in a manner that is fair to all. Without it we risk remaining a divided society all the more tragic for having unfulfilled our potential.

There was a comfort in the thought, a strange sort of personal comfort in being able to believe that some intelligence might have solved the riddle of that mysterious **equation** of the universe. And how, perhaps, that mysterious **equation** might tie in with the spiritual force that was idealistic brother to time and space and all those other elemental factors that held the universe together.

— Ch. 30 (Skirmish (1977))

Science is a differential **equation**. Religion is a boundary condition.

— Epigram to Robin Gandy (1954); reprinted in Andrew Hodges,

Albert Einstein described the left-hand side of the **equation** for his general theory of relativity as built on granite , the right-hand side on sand.

— Quoted in p.33 (Sand: The Never-ending Story)

One of the most frequently mentioned equations was Euler's **equation**, Respondents called it "the most profound mathematical statement ever written"; "uncanny and sublime"; "filled with cosmic beauty "; and "mind-blowing". Another asked: "What could be more mystical than an imaginary number interacting with real numbers to produce nothing ?" The **equation** contains nine basic concepts of mathematics once and only once in a single expression. These are: e (the base of natural logarithms); the exponent operation; ?; plus (or minus, depending on how you write it); multiplication; imaginary numbers; equals; one; and zero.

Like a Shakespearean sonnet that captures the very essence of love, or a painting that brings out the beauty of the human form that is far more than just skin deep, Euler's **equation** reaches down into the very depths of existence.

In the social **equation**, the value of a single life is nil; in the cosmic **equation**, it is infinite... Not only communism, but any political movement which implicitly relies on purely utilitarian ethics, must become a victim to the same fatal error. It is a fallacy as naïve as a mathematical teaser, and yet its consequences lead straight to Goya's Disasters, to the reign of the guillotine, the torture chambers of the Inquisition, or the cellars of the Lubianka.

— Arthur Koestler,

Let us suppose that we have set the problem of finding a solution to the **equation** This is a problem for which the Babylonians around 1700 BC found the excellent approximation ...This is the identical problem which Pythagoras asserted had no fractional solution and in whose honor he was supposed to have sacrificed a hecatomb of oxen the problem which caused the existentialist crisis in ancient Greek mathematics. The exists (as the diagonal of the unit square); yet it does not exist (as a fraction)!

No matter how effective your rebuttal may seem to be to you, a response will "bump" the problem into greater prominence and relevance in the search engine results, which then turns your headache into a migraine. This is doubly dangerous since "bumping" the negative information potentially introduces the "Streisand Effect" into the **equation**, which is something to avoid if at all possible. It is commonly defined as a phenomenon in which an attempt to censor or remove a piece of information on the web backfires, causing greater publicity.

Dale: I work at a college as a janitor even though I feel like I'm smarter than most of the people who go there. Sometimes I see an **equation** written on a blackboard, like half an **equation** and... I just figure it out.

Therapist: Is this Good Will Hunting?

Dale: No.

Therapist: It sounds a lot like the plot of Good Will Hunting.

Dale: Yeah, anyway. My best friend is Ben Affleck...
