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).

485 (number)
400 (four hundred) is the natural number following 399 and preceding 401. Mathematical properties 400 is the square of 20. 400 is the sum of the powers of 7 from 0 to 3, thus making it a repdigit in base 7 (1111). A circle is divided into 400 grads, which is equal to 360 degrees and 2π radians. (Degrees and radians are the SI accepted units). 400 is a self number in base 10, since there is no integer that added to the sum of its own digits results in 400. On the other hand, 400 is divisible by the sum of its own base 10 digits, making it a Harshad number. Other fields Four hundred is also * The Four Hundred (oligarchy) of ancient Athens. * An HTTP status code for a bad client request. * The Four Hundred (sometimes The Four Hundred Club) a phrase meaning the wealthiest, most famous, or most powerful social group (see, e.g., Ward McAllister), leading to the generation of such lists as the Forbes 400. * The Atari 400 home computer. * A former limited stop bus route whi ...

486 BC
__NOTOC__ Year 486 BC was a year of the pre-Julian Roman calendar. At the time, it was known as the Year of the Consulship of Viscellinus and Rutilus (or, less frequently, year 268 '' Ab urbe condita''). The denomination 486 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Persian Empire * Egypt revolts against Persian rule upon the death of king Darius I. The revolts, probably led by Libyans of the western Delta, are crushed the next year by Xerxes, who reduces Egypt to the status of a conquered province. Roman Republic * Rome enters into a new treaty with the Hernici. * During his third consulate, the Roman consul Spurius Cassius Vecellinus proposes an agrarian law to assist needy plebeians. The proposal is vehemently opposed by the patricians including the other consul Proculus Verginius Tricostus Rutilus, and the plebs turn against the patr ...

486 AD
__NOTOC__ Year 486 ( CDLXXXVI) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Basilius and Longinus (or, less frequently, year 1239 ''Ab urbe condita''). The denomination 486 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Europe * Battle of Soissons: Frankish forces under King Clovis I defeat the Gallo-Roman kingdom of Soissons ( Gaul). Roman rule under Syagrius ends. The land between the Somme and the Loire becomes a part of the Frankish Empire. Syagrius flees to the Visigoths (under King Alaric II), but Clovis threatens war, and he is handed over for execution. * Clovis I establishes his new residence at Soissons. He appoints Ragnachar, Frankish petty king (''regulus''), as his deputy ruler. By topic Religion * Persian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Year 1486 ( MCDLXXXVI) was a common year starting on Sunday (link will display the full Julian calendar for the year). Events January–December * January 18 – King Henry VII of England and Elizabeth of York are married, uniting the House of Lancaster and the House of York, after the Wars of the Roses. * February 16 – Archduke Maximilian I of Habsburg is elected King of the Romans at Frankfurt (crowned April 9 at Aachen). * February 18 – Lord Chaitanya Mahaprabhu is born in the town of Nadia, West Bengal, India, just after sunset. He is regarded as an incarnation, or avatar, of Lord Krsna, and later comes to inaugurate the sankirtana movement, or the chanting of the Holy Names of the Lord.

I486
The Intel 486, officially named i486 and also known as 80486, is a microprocessor. It is a higher-performance follow-up to the Intel 386. The i486 was introduced in 1989. It represents the fourth generation of binary compatible CPUs following the 8086 of 1978, the Intel 80286 of 1982, and 1985's i386. It was the first tightly- pipelined x86 design as well as the first x86 chip to include more than one million transistors. It offered a large on-chip cache and an integrated floating-point unit. A typical 50 MHz i486 executes around 40 million instructions per second (MIPS), reaching 50 MIPS peak performance. It is approximately twice as fast as the i386 or i286 per clock cycle. The i486's improved performance is thanks to its five-stage pipeline with all stages bound to a single cycle. The enhanced FPU unit on the chip was significantly faster than the i387 FPU per cycle. The intel 80387 FPU ("i387") was a separate, optional math coprocessor that was ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4-8-6
Under the Whyte notation for the classification of steam locomotives, a 4-8-6 locomotive would have had four leading wheels, eight coupled driving wheels and six trailing wheels. Other equivalent classifications are: *UIC classification: 2D3 (also known as German classification and Italian classification) *French classification: 243 *Turkish classification: 49 *Swiss classification: 4/9 This wheel arrangement was proposed by Lima Locomotive Works in 1949 as a continuation of their " Super Power" concept, essentially an expansion of the 4-8-4. A larger firebox similar to the ones on the 2-6-6-6 locomotives built by Lima would have been fitted, allowing for greater power at speed. Despite promotion by Lima, there is no firm evidence that an example of this type was ever built and no nickname was ever assigned to the arrangement. In 1949, few railroads were interested in new steam locomotives due to steady improvements in diesel-electric locomotives. It is possible that CB&Q 4-8 ...
