Blackboard bold originated from the attempt to write bold symbols on typewriters and blackboards that were legible but distinct, perhaps starting in the late 1950s in France, and then taking hold at the Princeton University mathematics department in the early 1960s.
Blackboard bold. The blackboard bold typeface is widely used for denoting the basic number systems. These systems are often also denoted by the corresponding uppercase bold letter. A clear advantage of blackboard bold is that these symbols cannot be confused with anything else.
Sets of numbers are typically bold or blackboard bold. The Greek letter forms used in mathematics are often different from those used in Greek-language text: they are designed to be used in isolation, not connected to other letters, and some use variant forms which are not normally used in current Greek typography.
The blackboard bold letter style originated in the 1960s to distinguish bold letters from ordinary letters on a blackboard or using a typewriter; in professionally typeset documents, bold fonts were used for the same purpose. Since then, blackboard bold has gradually gained currency, and is now commonly used in mathematical printing to denote ...
Mathematical operators and symbols in Unicode. Blackboard at the Laurent Schwartz Center for Mathematics, École Polytechnique. This article contains special characters. Without proper rendering support, you may see question marks, boxes, or other symbols.
This article contains Unicode mathematical symbols. Without proper rendering support, you may see question marks, boxes, or other symbols instead of mathematical symbols. The following table lists many specialized symbols commonly used in modern mathematics, ordered by their introduction date.
The set of real numbers, sometimes called "the reals", is traditionally denoted by a bold R, often using blackboard bold, . The adjective real, used in the 17th century by René Descartes, distinguishes real numbers from imaginary numbers such as the square roots of −1.
Number line. The order of the natural numbers shown on the number line. In elementary mathematics, a number line is a picture of a graduated straight line that serves as visual representation of the real numbers. Every point of a number line is assumed to correspond to a real number, and every real number to a point. [1]
Letters are typically used for naming—in mathematical jargon, one says representing—mathematical objects. The Latin and Greek alphabets are used extensively, but a few letters of other alphabets are also used sporadically, such as the Hebrew ℵ {\displaystyle \aleph } , Cyrillic Ш , and Hiragana よ .
Didone (typography) Didot's type in the Code civil des Français, printed by the company of Firmin Didot in 1804. Didone ( / diˈdoʊni /) is a genre of serif typeface that emerged in the late 18th century and was the standard style of general-purpose printing during the 19th century. It is characterized by: Narrow and unbracketed (hairline ...
