Natural Number
In mathematics, the natural numbers are those numbers used for counting (as in "there are ''six'' coins on the table") and ordering (as in "this is the ''third'' largest city in the country"). Numbers used for counting are called ''Cardinal number, cardinal numbers'', and numbers used for ordering are called ''Ordinal number, ordinal numbers''. Natural numbers are sometimes used as labels, known as ''nominal numbers'', having none of the properties of numbers in a mathematical sense (e.g. sports Number (sports), jersey numbers). Some definitions, including the standard ISO/IEC 80000, ISO 80000-2, begin the natural numbers with , corresponding to the non-negative integers , whereas others start with , corresponding to the positive integers Texts that exclude zero from the natural numbers sometimes refer to the natural numbers together with zero as the whole numbers, while in other writings, that term is used instead for the integers (including negative integers).

Palindromic Number
A palindromic number (also known as a numeral palindrome or a numeric palindrome) is a number (such as 16461) that remains the same when its digits are reversed. In other words, it has reflectional symmetry across a vertical axis. The term ''palindromic'' is derived from palindrome, which refers to a word (such as ''rotor'' or ''racecar'') whose spelling is unchanged when its letters are reversed. The first 30 palindromic numbers (in decimal) are: : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, 131, 141, 151, 161, 171, 181, 191, 202, … . Palindromic numbers receive most attention in the realm of recreational mathematics. A typical problem asks for numbers that possess a certain property ''and'' are palindromic. For instance: * The palindromic primes are 2, 3, 5, 7, 11, 101, 131, 151, ... . * The palindromic square numbers are 0, 1, 4, 9, 121, 484, 676, 10201, 12321, ... . It is obvious that in any base there are infinitely many palindr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seychelles
Seychelles (, ; ), officially the Republic of Seychelles (french: link=no, République des Seychelles; Creole: ''La Repiblik Sesel''), is an archipelagic state consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is east of mainland Africa. Nearby island countries and territories include the Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and Maldives and the Chagos Archipelago (administered by the United Kingdom as the British Indian Ocean Territory) to the east. It is the least populated sovereign African country, with an estimated 2020 population of 98,462. Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until coming under full British control in the late 18th century. Since proclaiming independence from the United Kingdom in 1976, it has developed from a largely agricultural society to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tata 1510/1512
The Tata 1510/1512 is the largest selling bus model seen regularly in India and neighbouring countries, and also in the Seychelles. Made by the industrial giant, Tata Motors, it combines good features and low ownership cost. It has the following features: * Engine:1512c using Front-mounted Tata-Cummins (Cummins 6BT 5.9L), turbocharged, intercooled. 1510 used TATA's own 697 series engine which is a follower of old TATA - Mercedes Benz Engine. Now it's not in production. And in BS4 era 1613 Bs4 follows the same engine with time required modifications. * Transmission: Manual, 6 forward + 1 reverse gears, with optional Overdrive Synchromesh * Steering: Integral Hydraulic Power Assisted Steering * Brakes: Full air, Dual circuit, S-CAM type Tata builds the chassis/cowl with engine and other framework.

1510 Charlois
1510 Charlois, provisional designation , is a carbonaceous Eunomia asteroid from the middle region of the asteroid belt, approximately 24 kilometers in diameter. It was discovered on 22 February 1939, by French astronomer André Patry at Nice Observatory in southeastern France, and later named after astronomer Auguste Charlois. Orbit and classification ''Charlois'' is a carbonaceous C-type asteroid and a member of the Eunomia family, a large group of otherwise mostly S-type asteroids and the most prominent family in the intermediate main-belt. It orbits the Sun in the central main-belt at a distance of 2.3–3.1 AU once every 4 years and 4 months (1,595 days). Its orbit has an eccentricity of 0.15 and an inclination of 12 ° with respect to the ecliptic. As no precoveries were taken and no prior identifications were made, the body's observation arc begins with its discovery observation in 1939.

WPGR (AM)
WPGR is a radio station serving the Pittsburgh area. The station, which is owned by St. Joseph Ministries, broadcasts at 1510 kHz, with a transmitter power of 5,000 watts daytime, 2,500 watts critical hours, and only 1 watt nighttime. The city of license is Monroeville, Pennsylvania. WPGR is a non-commercial Catholic radio station. 1510 AM is United States clear-channel frequency, on which WLAC in Nashville, Tennessee is the dominant Class A station. History Beginnings as WPSL It all began one day in the 1960s, when a group of friends just back from a fishing trip, approached local businessman Thomas M. “Tipper” Sylves with an idea they had been kicking around for a community radio station for Monroeville. Sylves was a prominent citizen in the community. He had been a coal miner, horse trader, lumberman, railroader, cattle baron and real estate broker, and he was always alert to new business opportunities – he listened. The first step was to see if there was an AM freq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pidgin (software)
Pidgin (formerly named Gaim) is a free and open-source multi-platform instant messaging client, based on a library named libpurple that has support for many instant messaging protocols, allowing the user to simultaneously log in to various services from a single application, with a single interface for both popular and obsolete protocols (from AOL to Discord), thus avoiding the hassle of having to deal with a new software for each device and protocol. , the number of Pidgin users was estimated to be over three million. Pidgin is widely used for its Off-the-Record Messaging (OTR) plugin, which offers end-to-end encryption. For this reason it is included in the privacy- and anonymity-focused operating system Tails. History The program was originally written by Mark Spencer, an Auburn University sophomore, as an emulation of AOL's IM program AOL Instant Messenger on Linux using the GTK+ toolkit.Herper, Matthew (July 16, 2002)"Better Instant Messaging Through Linux"Forbes. ...

Equidigital Number
In number theory, an equidigital number is a natural number in a given number base that has the same number of digits as the number of digits in its prime factorization in the given number base, including exponents but excluding exponents equal to 1. For example, in base 10, 1, 2, 3, 5, 7, and 10 (2 × 5) are equidigital numbers . All prime numbers are equidigital numbers in any base. A number that is either equidigital or frugal is said to be ''economical''. Mathematical definition Let b > 1 be the number base, and let K_b(n) = \lfloor \log_ \rfloor + 1 be the number of digits in a natural number n for base b. A natural number n has the prime factorisation : n = \prod_ p^ where v_p(n) is the ''p''-adic valuation of n, and n is an equidigital number in base b if : K_b(n) = \sum_ K_b(p) + \sum_ K_b(v_p(n)). Properties *Every prime number is equidigital. This also proves that there are infinitely many equidigital numbers. See also *Extravagant number *Frugal number *Smith number ...

1511 (number)
1000 or one thousand is the natural number following 999 and preceding 1001. In most English-speaking countries, it can be written with or without a comma or sometimes a period separating the thousands digit: 1,000. A group of one thousand things is sometimes known, from Ancient Greek, as a chiliad. A period of one thousand years may be known as a chiliad or, more often from Latin, as a millennium. The number 1000 is also sometimes described as a short thousand in medieval contexts where it is necessary to distinguish the Germanic concept of 1200 as a long thousand. Notation * The decimal representation for one thousand is ** 1000—a one followed by three zeros, in the general notation ; ** 1 × 103—in engineering notation, which for this number coincides with : ** 1 × 103 exactly—in scientific normalized exponential notation ; ** 1 E+3 exactly—in scientific E notation. * The SI prefix for a thousand units is "kilo-", abbreviated to "k"—for instance, a kilogra ...
