Eulogy – a speech or writing in praise of a person, especially one who recently died or retired.
projection. A projection is, roughly, a map from some space or object to another that omits some information on the object or space. For example, R 2 → R , ( x , y ) ↦ x {\displaystyle \mathbb {R} ^ {2}\to \mathbb {R} , (x,y)\mapsto x} is a projection and its restriction to a graph of a function, say, is also a projection.
This is a timeline of pure and applied mathematics history.It is divided here into three stages, corresponding to stages in the development of mathematical notation: a "rhetorical" stage in which calculations are described purely by words, a "syncopated" stage in which quantities and common algebraic operations are beginning to be represented by symbolic abbreviations, and finally a "symbolic ...
Mathematical notation is widely used in mathematics, science, and engineering for representing complex concepts and properties in a concise, unambiguous, and accurate way. For example, the physicist Albert Einstein 's formula E = m c 2 {\displaystyle E=mc^{2}} is the quantitative representation in mathematical notation of mass–energy ...
Abstract algebra. The permutations of the Rubik's Cube form a group, a fundamental concept within abstract algebra. In mathematics, more specifically algebra, abstract algebra or modern algebra is the study of algebraic structures, which are sets with specific operations acting on their elements. [1] Algebraic structures include groups, rings ...
Zeugma and syllepsis. In rhetoric, zeugma (/ ˈzjuːɡmə / ⓘ; from the Ancient Greek ζεῦγμα, zeûgma, lit. "a yoking together" [1]) and syllepsis (/ sɪˈlɛpsɪs /; from the Ancient Greek σύλληψις, sullēpsis, lit. "a taking together" [2]) are figures of speech in which a single phrase or word joins different parts of a ...
In mathematics and logic, ambiguity can be considered to be an instance of the logical concept of underdetermination—for example, = leaves open what the value of is—while overdetermination, except when like =, =, =, is a self-contradiction, also called inconsistency, paradoxicalness, or oxymoron, or in mathematics an inconsistent system ...
Parallelism is a rhetorical device that compounds words or phrases that have equivalent meanings so as to create a definite pattern. This structure is particularly effective when "specifying or enumerating pairs or series of like things". [1] A scheme of balance, parallelism represents "one of the basic principles of grammar and rhetoric". [2]
