G. H. Hardy, A Mathematician's Apology (1940) He [Russell] said once, after some contact with the Chinese language, that he was horrified to find that the language of Principia Mathematica was an Indo-European one. John Edensor Littlewood, Littlewood's Miscellany (1986) The Principia Mathematica (often abbreviated PM) is a three-volume work on the foundations of mathematics written by ...
Mathematical fallacy. In mathematics, certain kinds of mistaken proof are often exhibited, and sometimes collected, as illustrations of a concept called mathematical fallacy. There is a distinction between a simple mistake and a mathematical fallacy in a proof, in that a mistake in a proof leads to an invalid proof while in the best-known ...
Omer (unit) Sheaves of wheat: one sheaf is approximately one omer in dry volume. The omer ( Hebrew: עֹ֫מֶר ‘ōmer) is an ancient Israelite unit of dry measure used in the era of the Temple in Jerusalem and also known as an isaron. [ 1] It is used in the Bible as an ancient unit of volume for grains and dry commodities, and the Torah ...
In set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. [ 1] It is one of the fundamental operations through which sets can be combined and related to each other. A nullary union refers to a union of zero ( ) sets and it is by definition equal to the empty set.
Euler's identity. In mathematics, Euler's identity[ note 1] (also known as Euler's equation) is the equality where. is pi, the ratio of the circumference of a circle to its diameter. Euler's identity is named after the Swiss mathematician Leonhard Euler. It is a special case of Euler's formula when evaluated for .
Equality (mathematics) In mathematics, equality is a relationship between two quantities or, more generally, two mathematical expressions, asserting that the quantities have the same value, or that the expressions represent the same mathematical object. Equality between A and B is written A = B, and pronounced " A equals B ".
A gross refers to a group of 144 items (a dozen dozen or a square dozen, 12 2). [1] [2] A great gross refers to a group of 1,728 items (a dozen gross or a cubic dozen, 12 3). [1] [2] A small gross [3] or a great hundred [4] refers to a group of 120 items (ten dozen, 10×12). The term can be abbreviated gr. or gro., and dates from the early 15th ...
Euclid–Euler theorem. The Euclid–Euler theorem is a theorem in number theory that relates perfect numbers to Mersenne primes. It states that an even number is perfect if and only if it has the form 2p−1(2p − 1), where 2p − 1 is a prime number. The theorem is named after mathematicians Euclid and Leonhard Euler, who respectively proved ...
