MathWorld
''MathWorld'' is an online mathematics reference work, created and largely written by Eric W. Weisstein. It is sponsored by and licensed to Wolfram Research, Inc. and was partially funded by the National Science Foundation's National Science Digital Library grant to the University of Illinois at Urbana–Champaign. History Eric W. Weisstein, the creator of the site, was a physics and astronomy student who got into the habit of writing notes on his mathematical readings. In 1995 he put his notes online and called it "Eric's Treasure Trove of Mathematics." It contained hundreds of pages/articles, covering a wide range of mathematical topics. The site became popular as an extensive single resource on mathematics on the web. In 1998, he made a contract with CRC Press and the contents of the site were published in print and CD-ROM form, titled ''CRC Concise Encyclopedia of Mathematics''. The free online version became only partially accessible to the public. In 1999 Weisstein we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PlanetMath
PlanetMath is a free content, free, collaborative, mathematics online encyclopedia. Intended to be comprehensive, the project is currently hosted by the University of Waterloo. The site is owned by a US-based nonprofit corporation, "PlanetMath.org, Ltd". PlanetMath was started when the popular free online mathematics encyclopedia MathWorld was temporarily taken offline for 12 months by a court injunction as a result of the CRC Press lawsuit against the Wolfram Research company and its employee (and MathWorld's author) Eric Weisstein. Materials The main PlanetMath focus is on encyclopedia, encyclopedic entries. It formerly operated a self-hosted forum, but now encourages discussion via Gitter. An all-inclusive PlanetMath ''Free Encyclopedia'' book of 2,300 pages is available for the encyclopedia contents up to 2006 as a free download PDF file. Content development model PlanetMath implements a specific content creation system called ''authority model''. An author who starts a ne ...

CRC Press
The CRC Press, LLC is an American publishing group that specializes in producing technical books. Many of their books relate to engineering, science and mathematics. Their scope also includes books on business, forensics and information technology. CRC Press is now a division of Taylor & Francis, itself a subsidiary of Informa. History The CRC Press was founded as the Chemical Rubber Company (CRC) in 1903 by brothers Arthur, Leo and Emanuel Friedman in Cleveland, Ohio, based on an earlier enterprise by Arthur, who had begun selling rubber laboratory aprons in 1900. The company gradually expanded to include sales of laboratory equipment to chemist A chemist (from Greek ''chēm(ía)'' alchemy; replacing ''chymist'' from Medieval Latin ''alchemist'') is a graduated scientist trained in the study of chemistry, or an officially enrolled student in the field.

Mathematics is a field of study that discovers and organizes methods, theories and theorems that are developed and proved for the needs of empirical sciences and mathematics itself. There are many areas of mathematics, which include number theory (the study of numbers), algebra (the study of formulas and related structures), geometry (the study of shapes and spaces that contain them), analysis (the study of continuous changes), and set theory (presently used as a foundation for all mathematics). Mathematics involves the description and manipulation of abstract objects that consist of either abstractions from nature orin modern mathematicspurely abstract entities that are stipulated to have certain properties, called axioms. Mathematics uses pure reason to prove properties of objects, a ''proof'' consisting of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstracti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wolfram Mathematica
Wolfram (previously known as Mathematica and Wolfram Mathematica) is a software system with built-in libraries for several areas of technical computing that allows machine learning, statistics, symbolic computation, data manipulation, network analysis, time series analysis, NLP, optimization, plotting functions and various types of data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other programming languages. It was conceived by Stephen Wolfram, and is developed by Wolfram Research of Champaign, Illinois. The Wolfram Language is the programming language used in ''Mathematica''. Mathematica 1.0 was released on June 23, 1988 in Champaign, Illinois and Santa Clara, California. Mathematica's Wolfram Language is fundamentally based on Lisp; for example, the Mathematica command Most is identically equal to the Lisp command butlast. There is a substantial literature on the development of computer algebra systems (CAS). __TOC ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stipulation
In United States law, a stipulation is a formal legal acknowledgment and agreement made between opposing parties before a pending hearing or trial. For example, both parties might stipulate to certain facts and so not have to argue them in court. After the stipulation is entered into, it is presented to the judge. The word is derived from the Latin word ''stipula'' "straw." The Ancient Roman In modern historiography, ancient Rome is the Roman people, Roman civilisation from the founding of Rome, founding of the Italian city of Rome in the 8th century BC to the Fall of the Western Roman Empire, collapse of the Western Roman Em ... custom was that the negotiating parties, upon reaching an agreement, broke a straw as a sign of their agreement and wrote down the agreement's rules (''stipulationes'').Caesar and Christ, Will Durant, Simon and Schuster, New York, 1944 References Legal terminology {{law-term-stub ...

Injunction
An injunction is an equitable remedy in the form of a special court order compelling a party to do or refrain from doing certain acts. It was developed by the English courts of equity but its origins go back to Roman law and the equitable remedy of the "interdict". "When a court employs the extraordinary remedy of injunction, it directs the conduct of a party, and does so with the backing of its full coercive powers."'' Nken v. Holder''556 U.S. 418, 428 (2009) (citation and internal quotation marks omitted). A party that fails to comply with an injunction faces criminal or civil penalties, including possible monetary sanctions and even imprisonment. They can also be charged with contempt of court. Rationale The injunction is an equitable remedy that was created by the English courts of equity. Like other equitable remedies, it has traditionally been given when a wrong cannot be effectively remedied by an award of money damages. (The doctrine that reflects this is the req ...

Privately Held Company
A privately held company (or simply a private company) is a company whose Stock, shares and related rights or obligations are not offered for public subscription or publicly negotiated in their respective listed markets. Instead, the Private equity, company's stock is offered, owned, traded or exchanged privately, also known as "over-the-counter (finance), over-the-counter". Related terms are unlisted organisation, unquoted company and private equity. Private companies are often less well-known than their public company, publicly traded counterparts but still have major importance in the world's economy. For example, in 2008, the 441 list of largest private non-governmental companies by revenue, largest private companies in the United States accounted for $1.8 trillion in revenues and employed 6.2 million people, according to ''Forbes''. In general, all companies that are not owned by the government are classified as private enterprises. This definition encompasses both publ ...
