Babylonian mathematics were written using a sexagesimal (base-60) numeral system. From this derives the modern-day usage of 60 seconds in a minute, 60 minutes in an hour, and 360 (60 × 6) degrees in a circle, as well as the use of minutes and seconds of arc to denote fractions of a degree. Babylonian advances in mathematics were facilitated by ...
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 ...
When defining a term, do not use the phrase "if and only if". For example, instead of A function f is even if and only if f(−x) = f(x) for all x; write A function f is even if f(−x) = f(x) for all x. If it is reasonable to do so, rephrase the sentence to avoid the use of the word "if" entirely. For example,
Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.
Stephen King uses many epigraphs in his writing, usually to mark the beginning of another section in a novel. An unusual example is The Stand wherein he uses lyrics from certain songs to express the metaphor used in a particular part.
Babel-17 is a 1966 science fiction novel by American writer Samuel R. Delany in which the Sapir–Whorf hypothesis (that language influences thought and perception) plays an important part. [2] It was joint winner of the Nebula Award for Best Novel in 1967 (with Flowers for Algernon) [3] and was also nominated for the Hugo Award for Best Novel ...
A monk who was writing in Old English at the same time as Ælfric and Wulfstan was Byrhtferth of Ramsey, whose book Handboc was a study of mathematics and rhetoric. He also produced a work entitled Computus, which outlined the practical application of arithmetic to the calculation of calendar days and movable feasts, as well as tide tables. [68]
The use of a series of three elements is also a well-known feature of public oratory. Max Atkinson, in his book on oratory entitled Our Masters' Voices, [19] gives examples of how public speakers use three-part phrases to generate what he calls 'claptraps', evoking audience applause.
