International Day Of Mathematics
The International Day of Mathematics is 14 March. It is also known as the Pi Day, because the mathematical constant (pi) can be rounded down to 3.14. UNESCO's 40th General Conference decided Pi Day as the International Day of Mathematics in November 2019.- See also * (pi) * Pi Day References External links {{CommonscatOfficial website of the International Day of MathematicsUNESCO page on the International Day of Mathematics数学漫谈(A Tour of Mathematics), a public lecture (in Chinese) delivered by ProfessoYa-xiang Yuan(President of International Council for Industrial and Applied Mathematics The International Council for Industrial and Applied Mathematics (ICIAM) is an organisation for professional applied mathematics societies and related organisations.

Significant Figure
Significant figures (also known as the significant digits, ''precision'' or ''resolution'') of a number in positional notation are digits in the number that are reliable and necessary to indicate the quantity of something. If a number expressing the result of a measurement (e.g., length, pressure, volume, or mass) has more digits than the number of digits allowed by the measurement resolution, then only as many digits as allowed by the measurement resolution are reliable, and so only these can be significant figures. For example, if a length measurement gives 114.8 mm while the smallest interval between marks on the ruler used in the measurement is 1 mm, then the first three digits (1, 1, and 4, showing 114 mm) are certain and so they are significant figures. Digits which are uncertain but ''reliable'' are also considered significant figures. In this example, the last digit (8, which adds 0.8 mm) is also considered a significant figure even though there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pi Day
Pi Day is an annual celebration of the mathematical constant (pi). Pi Day is observed on March 14 (3/14 in the ''month/day'' format) since 3, 1, and 4 are the first three significant figures of . It was founded in 1988 by Larry Shaw, an employee of the San Francisco, California science museum, the Exploratorium. Celebrations often involve eating pie or holding pi recitation competitions. In 2009, the United States House of Representatives supported the designation of Pi Day.United States. Cong. House.

UNESCO
The United Nations Educational, Scientific and Cultural Organization is a specialized agency of the United Nations (UN) aimed at promoting world peace and security through international cooperation in education, arts, sciences and culture. It has 193 member states and 12 associate members, as well as partners in the non-governmental, intergovernmental and private sector. Headquartered at the World Heritage Centre in Paris, France, UNESCO has 53 regional field offices and 199 national commissions that facilitate its global mandate. UNESCO was founded in 1945 as the successor to the League of Nations's International Committee on Intellectual Cooperation.English summary). Its constitution establishes the agency's goals, governing structure, and operating framework. UNESCO's founding mission, which was shaped by the Second World War, is to advance peace, sustainable development and human rights by facilitating collaboration and dialogue among nations. It pursues this objective t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Council For Industrial And Applied Mathematics
The International Council for Industrial and Applied Mathematics (ICIAM) is an organisation for professional applied mathematics societies and related organisations. The current (2020) President is Ya-xiang Yuan. History Until 1999 the Council was known as the Committee for International Conferences on Industrial and Applied Mathematics (CICIAM). Formed in 1987 with the start of the ICIAM conference series, this committee represented the leaders of four applied mathematics societies: the Gesellschaft für Angewandte Mathematik und Mechanik (GAMM), in Germany, the Institute of Mathematics and its Applications (IMA), in England, the Society for Industrial and Applied Mathematics (SIAM), in the USA, and the Société de Mathématiques Appliquées et Industrielles (SMAI), in France. The first two presidents of the council, Roger Temam and Reinhard Mennicken, oversaw the addition of several other societies as members and associate members of the council; as of 2015 it had 21 full mem ...

Mathematics And Culture
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...
