Qq: Quote Mine



The practice of quoting out of context, sometimes referred to as "contextomy" or "quote mining", is a logical fallacy and type of false attribution in which a passage is removed from its surrounding matter in such a way as to distort its intended meaning.[1] (Wikipedia's Definition)

Ee: Ephemeris


Plural ephemerides (f-mr-dz)
A table giving the coordinates of a celestial body at specific times during a given period. Ephemerides can be used by navigators to determine their longitude while at sea and by astronomers in following objects such as comets. The use of computers has allowed modern ephemerides to determine celestial positions with far greater accuracy than in earlier publications.

Gg: Golden Mean-Golden Ratio


Golden Mean: In philosophy, especially that of Aristotle, the golden mean is the desirable middle between two extremes, one of excess and the other of deficiency. For example courage, a virtue, if taken to excess would manifest as recklessness and if deficient as cowardice.

In Context:
...the planets correlate with each other via simple mathematical relationships, but they also do so with an uncanny and profound association with various forms of The Golden Mean.

The Golden Mean or Golden Ratio is one of the most intriguing number in mathematics. It is commonly denoted by the Greek letter, phi, and is given in either to two forms by the equalities: F º 1.618033989... and f º 0.618033989... (where “...” means a continuation of the numbers -- See Transcendental Numbers). The Golden Mean was known to the ancients (and moderns), who considered these numbers so sacred that monuments from the Giza Pyramids and Greek Parthenon to Notre Dame Cathedral and the United Nations Building in New York City have been based on these fundamentals of Sacred Geometry.

Mm: Monad (Gr. Monas, a unit)



1. In Greek usage, originally the number one. Later, any individual or metaphysical unit.
2. Bruno named his metaphysical units monads to distinguish them from the Democritean atoms. The monads, centers of the world life, are both psychic and spatial individuals.
3. Leibniz (borrowing the term possibly from Augustine, Bruno or Protestant scholastics) identified the monads with the metaphysical individuals or souls, conceived as unextended, active, indivisible, naturally indestructible, teleological substances ideally related in a system of pre-established harmony.
4. By extension of Leibnizian usage, a soul, self, metaphysical unit, when conceived as possessing an autonomous life, and irrespective of the nature of its relations to beings beyond it.

Ff: Fractions


n.
1. Mathematics An expression that indicates the quotient of two quantities, such as 1/3 .
2. A disconnected piece; a fragment.
3. A small part; a bit: moved a fraction of a step.
4. A chemical component separated by fractionation.

[Middle English fraccioun, a breaking, from Anglo-Norman, from Late Latin frcti, frctin-, from Latin frctus, past participle of frangere, to break; see bhreg- in Indo-European roots.]
Word History: Our word fraction did not originally have a mathematical sense. It goes back ultimately to the Latin verb frangere, "to break." From the stem of the past participle frctus is derived Late Latin frcti (stem frctin-), "a breaking" or "a breaking in pieces," as in the breaking of the Eucharistic Host. In Medieval Latin the word frcti developed its mathematical sense, which was taken into Middle English along with the word. The earliest recorded sense of our word is "an aliquot part of a unit, a fraction or subdivision," found in a work by Chaucer written about 1400. One of the next recorded instances of the word recalls its origins, referring to the "brekying or fraccioun" of a bone.

Rr: Reductio ad absurdum



Reductio ad absurdum (Latin: "reduction to the absurd")[1] in formal logic is an argument to refute a proposition (or set of propositions), by showing that it leads to a logically absurd consequence.[2] In other words: the proposition is shown by proper inspection to be simply untenable within the rules of logic, because it necessarily leads to a self-contradictory consequence.

An unstable hypothesis creates an improbable seam. (Paraphrased from Lee Smolin Trouble with Physics)

Ff: Future Shock



Future Shock is a book written by the sociologist and futurologist Alvin Toffler in 1970. It grew out of an article "The Future as a Way of Life" in Horizon magazine, Summer 1965 issue.[1][2][3][4] The book has sold over 6 million copies and has been widely translated.
Toffler's shortest definition of future shock is a personal perception of "too much change in too short a period of time".

Pp: Propinquity Effect


propinquity
Noun
Formal nearness in time, place, or relationship [Latin propinquus near]

Collins Essential English Dictionary 2nd Edition 2006 © HarperCollins Publishers 2004, 2006


The sense of the word "propinquity" as given here is a specialised one. For a more general definition of the word, see in the Wiktionary.

In social psychology, propinquity (from Latin propinquitas, nearness) is one of the main factors leading to interpersonal attraction. It refers to the physical or psychological proximity between people. Two people living on the same floor of a building, for example, have a higher propinquity than those living on different floors. Propinquity can mean physical proximity, a kinship between people, or a similarity in nature between things. Propinquity is also one of the factors, set out by Jeremy Bentham, used to measure the amount of pleasure in a method known as felicific calculus.

Propinquity effect

The propinquity effect is the tendency for people to form friendships or romantic relationships with those whom they encounter often. In other words, relationships tend to be formed between those who have a high propinquity. It was first theorized by psychologists Leon Festinger, Stanley Schachter, Kurt Lewin and Kurt Bach in what came to be called as the Westgate studies conducted at MIT (1950). The typical venn diagram used to represent the propinquity effect is shown below where U = universe, A = set A, B = set B, and S = similarity:



The sets are basically any relevant subject matter about a person, or persons, or non-persons, etc; depending on the context of the use of the word. Propinquity can be more than just physical distance. Residents of an apartment building living near a stairway, as an example, tend to have more friends from other floors than others. The propinquity effect is usually explained by the mere exposure effect, which holds that the more exposure a stimulus gets, the more likeable it becomes.
