Natural Number
In mathematics, the natural numbers are the numbers 0, 1, 2, 3, and so on, possibly excluding 0. Some start counting with 0, defining the natural numbers as the non-negative integers , while others start with 1, defining them as the positive integers Some authors acknowledge both definitions whenever convenient. Sometimes, the whole numbers are the natural numbers as well as zero. In other cases, the ''whole numbers'' refer to all of the integers, including negative integers. The counting numbers are another term for the natural numbers, particularly in primary education, and are ambiguous as well although typically start at 1. The natural numbers are used for counting things, like "there are ''six'' coins on the table", in which case they are called ''cardinal numbers''. They are also used to put things in order, like "this is the ''third'' largest city in the country", which are called ''ordinal numbers''. Natural numbers are also used as labels, like Number (sports), jersey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thabit Number
In number theory, a Thabit number, Thâbit ibn Qurra number, or 321 number is an integer of the form 3 \cdot 2^n - 1 for a non-negative integer ''n''. The first few Thabit numbers are: : 2, 5, 11, 23, 47, 95, 191, 383, 767, 1535, 3071, 6143, 12287, 24575, 49151, 98303, 196607, 393215, 786431, 1572863, ... The 9th century mathematician, physician, astronomer and translator Thābit ibn Qurra is credited as the first to study these numbers and their relation to amicable numbers. Properties The binary representation of the Thabit number 3·2''n''−1 is ''n''+2 digits long, consisting of "10" followed by ''n'' 1s. The first few Thabit numbers that are prime (Thabit primes or 321 primes): :2, 5, 11, 23, 47, 191, 383, 6143, 786431, 51539607551, 824633720831, ... , there are 68 known prime Thabit numbers. Their ''n'' values are: :0, 1, 2, 3, 4, 6, 7, 11, 18, 34, 38, 43, 55, 64, 76, 94, 103, 143, 206, 216, 306, 324, 391, 458, 470, 827, 1274, 3276, 4204, 5134, 7559, 12676 ...

Phillips Code
The Phillips Code is a brevity code (shorthand) compiled and expanded in 1879 by Walter P. Phillips (then of the Associated Press) for the rapid transmission of telegraph messages, including press reports. Overview It was compiled in 1879 by Walter P. Phillips, who explained that he was in large part putting down the collective experience of generations of telegraph operators. In the introduction to the 1907 edition of his book, "The Phillips Code: A Thoroughly Tested Method of Shorthand Arranged for Telegraphic Purposes. And Contemplating the Rapid Transmission of Press Reports; Also Intended to be Used as an Easily Acquired Method for General Newspaper and Court Reporting," Phillips wrote, "Research suggests that at one time, commercial telegraphs and railroads had numerical codes that contained at least 100 groupings. Few survived beyond the turn of the century. The compilation in this book represents the consensus of many whose duties brought them into close contact with ...

Alláh-u-Abhá
Alláh-u-Abhá (, ''Allāhu Abhā'': "God is Most Glorious") is an invocation in the Bahá'í Faith, and an expression of the "Greatest Name". It is used as a greeting that Baháʼís may use when they meet each other. It can be compared to the ''Takbir, takbīr'' and ''Tasbih, tasbīḥ'' of Islam, i.e. the Arabic phrases ''Allāhu ʾAkbar'' ("God is Great") and ''Subḥān Allāh'' ("How Pure is God"). One of the obligations Baháʼu'lláh set for his followers is to engage in a Prayer in the Baháʼí Faith, daily meditation that involves repeating the phrase ''Alláh-u-Abhá'' 95 times. Nader Saiedi explains that the significance of the number 95 originates from the ''Persian Bayán'', where the Báb states that ninety-five Hurufism, stands for the numerical value of "for God" (''lillāh''), symbolizing the recognition of the Manifestation of God (Baháʼí Faith), Manifestation of God and obedience to his laws, which are inseparable from each other, as confirmed by Baháʼu'l ...

Baháʼí Faith
The Baháʼí Faith is a religion founded in the 19th century that teaches the Baháʼí Faith and the unity of religion, essential worth of all religions and Baháʼí Faith and the unity of humanity, the unity of all people. Established by Baháʼu'lláh, it initially developed in Iran and parts of the Middle East, where it has faced Persecution of Baháʼís, ongoing persecution since its inception. The religion has 5-8 million adherents (known as Baháʼís) spread throughout most of the world's countries and territories. The Baháʼí Faith has three central figures: the Báb (1819–1850), executed for heresy, who taught that a prophet similar to Jesus and Muhammad would soon appear; Baháʼu'lláh (1817–1892), who claimed to be said prophet in 1863 and who had to endure both exile and imprisonment; and his son, ʻAbdu'l-Bahá (1844–1921), who made teaching trips to Europe and the United States after his release from confinement in 1908.

Statistics
Statistics (from German language, German: ', "description of a State (polity), state, a country") is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data. In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied. Populations can be diverse groups of people or objects such as "all people living in a country" or "every atom composing a crystal". Statistics deals with every aspect of data, including the planning of data collection in terms of the design of statistical survey, surveys and experimental design, experiments. When census data (comprising every member of the target population) cannot be collected, statisticians collect data by developing specific experiment designs and survey sample (statistics), samples. Representative sampling assures that inferences and conclusions can reasonably extend from the sample ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mertens Function
In number theory, the Mertens function is defined for all positive integers ''n'' as : M(n) = \sum_^n \mu(k), where \mu(k) is the Möbius function. The function is named in honour of Franz Mertens. This definition can be extended to positive real numbers as follows: : M(x) = M(\lfloor x \rfloor). Less formally, M(x) is the count of square-free integers up to ''x'' that have an even number of prime factors, minus the count of those that have an odd number. The first 143 ''M''(''n'') values are The Mertens function slowly grows in positive and negative directions both on average and in peak value, oscillating in an apparently chaotic manner passing through zero when ''n'' has the values :2, 39, 40, 58, 65, 93, 101, 145, 149, 150, 159, 160, 163, 164, 166, 214, 231, 232, 235, 236, 238, 254, 329, 331, 332, 333, 353, 355, 356, 358, 362, 363, 364, 366, 393, 401, 403, 404, 405, 407, 408, 413, 414, 419, 420, 422, 423, 424, 425, 427, 428, ... .

Polygonal Number
In mathematics, a polygonal number is a Integer, number that counts dots arranged in the shape of a regular polygon. These are one type of 2-dimensional figurate numbers. Polygonal numbers were first studied during the 6th century BC by the Ancient Greeks, who investigated and discussed properties of Pronic number, oblong, Triangular Number, triangular, and Square number, square numbers. Definition and examples The number 10 for example, can be arranged as a triangle (see triangular number): : But 10 cannot be arranged as a square (geometry), square. The number 9, on the other hand, can be (see square number): : Some numbers, like 36, can be arranged both as a square and as a triangle (see square triangular number): : By convention, 1 is the first polygonal number for any number of sides. The rule for enlarging the polygon to the next size is to extend two adjacent arms by one point and to then add the required extra sides between those points. In the following diagrams, ...
