A mythical number is a number used and accepted as deriving from scientific investigation and/or careful selection, but whose origin is unknown and whose basis is unsubstantiated. An example is the number 48 billion, which has often been accepted as the number of dollars per year of identity theft. This number "has appeared in hundreds of news stories, including a New York Times piece" [1] despite the fact that it has been shown repeatedly to be highly inaccurate. The term was coined in 1971 by Max Singer, one of the founders of the Hudson Institute.
The origins of such numbers are akin to those of urban legends and may include (among others):
A building society is a financial institution owned by its members as a mutual organization, which offers banking and related financial services, especially savings and mortgage lending. They exist in the United Kingdom, Australia and New Zealand, and formerly in Ireland and several Commonwealth countries, including South Africa as mutual banks. They are similar to credit unions, but rather than promoting thrift and offering unsecured and business loans, the purpose of a building society is to provide home mortgages to members. Borrowers and depositors are society members, setting policy and appointing directors on a one-member, one-vote basis. Building societies often provide other retail banking services, such as current accounts, credit cards and personal loans. The term "building society" first arose in the 19th century in Great Britain from cooperative savings groups.
Georg Ferdinand Ludwig Philipp Cantor was a mathematician. He played a pivotal role in the creation of set theory, which has become a fundamental theory in mathematics. Cantor established the importance of one-to-one correspondence between the members of two sets, defined infinite and well-ordered sets, and proved that the real numbers are more numerous than the natural numbers. Cantor's method of proof of this theorem implies the existence of an infinity of infinities. He defined the cardinal and ordinal numbers and their arithmetic. Cantor's work is of great philosophical interest, a fact he was well aware of.
Interlingua is an international auxiliary language (IAL) developed between 1937 and 1951 by the American International Auxiliary Language Association (IALA). It is a constructed language of the "naturalistic" variety, whose vocabulary, grammar, and other characteristics are derived from natural languages. Interlingua literature maintains that (written) Interlingua is comprehensible to the hundreds of millions of people who speak Romance languages, though it is actively spoken by only a few hundred.
In linguistics, a numeral in the broadest sense is a word or phrase that describes a numerical quantity. Some theories of grammar use the word "numeral" to refer to cardinal numbers that act as a determiner that specify the quantity of a noun, for example the "two" in "two hats". Some theories of grammar do not include determiners as a part of speech and consider "two" in this example to be an adjective. Some theories consider "numeral" to be a synonym for "number" and assign all numbers to a part of speech called "numerals". Numerals in the broad sense can also be analyzed as a noun, as a pronoun, or for a small number of words as an adverb.
A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words. More universally, individual numbers can be represented by symbols, called numerals; for example, "5" is a numeral that represents the number five. As only a relatively small number of symbols can be memorized, basic numerals are commonly organized in a numeral system, which is an organized way to represent any number. The most common numeral system is the Hindu–Arabic numeral system, which allows for the representation of any number using a combination of ten fundamental numeric symbols, called digits. In addition to their use in counting and measuring, numerals are often used for labels, for ordering, and for codes. In common usage, a numeral is not clearly distinguished from the number that it represents.
Postal codes used in the United Kingdom, British Overseas Territories and Crown dependencies are known as postcodes. They are alphanumeric and were adopted nationally between 11 October 1959 and 1974, having been devised by the General Post Office. A full postcode is known as a "postcode unit" and designates an area with several addresses or a single major delivery point.
A ship class is a group of ships of a similar design. This is distinct from a ship type, which might reflect a similarity of tonnage or intended use. For example, USS Carl Vinson is a nuclear aircraft carrier of the Nimitz class.
A numerical digit is a single symbol used alone or in combinations, to represent numbers in a positional numeral system. The name "digit" comes from the fact that the ten digits of the hands correspond to the ten symbols of the common base 10 numeral system, i.e. the decimal digits.
An exit number is a number assigned to a road junction, usually an exit from a freeway. It is usually marked on the same sign as the destinations of the exit. In some countries, such as the United States, it is also marked on a sign in the gore.
In ancient times, only the Sun and Moon, a few stars, and the most easily visible planets had names. Over the last few hundred years, the number of identified astronomical objects has risen from hundreds to over a billion, and more are discovered every year. Astronomers need to be able to assign systematic designations to unambiguously identify all of these objects, and at the same time give names to the most interesting objects, and where relevant, features of those objects.
In economics, the lump of labor fallacy is the misconception that there is a finite amount of work—a lump of labor—to be done within an economy which can be distributed to create more or fewer jobs. It was considered a fallacy in 1891 by economist David Frederick Schloss, who held that the amount of work is not fixed.
A tax file number (TFN) is a unique identifier issued by the Australian Taxation Office (ATO) to each taxpaying entity — an individual, company, superannuation fund, partnership, or trust. Not all individuals have a TFN, and a business has both a TFN and an Australian Business Number (ABN). If a business earns income as part of carrying on its business, it may quote its ABN instead of its TFN.
A national identification number, national identity number, or national insurance number or JMBG/EMBG is used by the governments of many countries as a means of tracking their citizens, permanent residents, and temporary residents for the purposes of work, taxation, government benefits, health care, and other governmentally-related functions.
The Common Vulnerabilities and Exposures (CVE) system provides a reference method for publicly known information-security vulnerabilities and exposures. The United States' National Cybersecurity FFRDC, operated by The MITRE Corporation, maintains the system, with funding from the US National Cyber Security Division of the US Department of Homeland Security. The system was officially launched for the public in September 1999.
The Roud Folk Song Index is a database of around 250,000 references to nearly 25,000 songs collected from oral tradition in the English language from all over the world. It is compiled by Steve Roud. Roud's Index is a combination of the Broadside Index and a "field-recording index" compiled by Roud. It subsumes all the previous printed sources known to Francis James Child and includes recordings from 1900 to 1975. Until early 2006, the index was available by a CD subscription; now it can be found online on the Vaughan Williams Memorial Library website, maintained by the English Folk Dance and Song Society (EFDSS). A partial list is also available at List of folk songs by Roud number.
Regular numbers are numbers that evenly divide powers of 60 (or, equivalently, powers of 30). Equivalently, they are the numbers whose only prime divisors are 2, 3, and 5. As an example, 602 = 3600 = 48 × 75, so as divisors of a power of 60 both 48 and 75 are regular.
The "eternal return" is an idea for interpreting religious behavior proposed by the historian Mircea Eliade; it is a belief expressed through behavior that one is able to become contemporary with or return to the "mythical age"—the time when the events described in one's myths occurred. It should be distinguished from the philosophical concept of eternal return.
A credit card is a payment card, usually issued by a bank, allowing its users to purchase goods or services or withdraw cash on credit. Using the card thus accrues debt that has to be repaid later. Credit cards are one of the most widely used forms of payment across the world.
A NATO Stock Number, or National Stock Number (NSN) as it is known in the US, is a 13-digit numeric code used by the NATO military alliance, identifying all the 'standardized material items of supply' as they have been recognized by all member states of NATO. Pursuant to the NATO Standardization Agreements, the NSN has come to be used in all treaty countries. However, many countries that use the NSN program are not members of NATO. A two-digit Material Management Aggregation Code (MMAC) suffix may also be appended, to denote asset end use but it is not considered part of the NSN.
Seven Magic: The Gathering core sets have been released since 2009: Magic 2010, Magic 2011, Magic 2012, Magic 2013, Magic 2014, Magic 2015, and Magic Origins. Unlike 10th Edition and previous core sets, roughly half of each core set was entirely new cards. Beginning with Magic 2010, Wizards decided to introduce new cards into the Core Set so that they could be relevant for both new players as well as veterans. Starting with Magic 2011, core sets have included "returning mechanics", or non-evergreen keywords with cards printed in just one core set. All of these core sets were released in the summer of the year prior to the year in the title - for example, Magic 2010 was released in 2009.
