Helge Von Koch
Niels Fabian Helge von Koch (25 January 1870 – 11 March 1924) was a Swedish mathematician who gave his name to the famous fractal known as the Koch snowflake, one of the earliest fractal curves to be described. He was born to Swedish nobility. His grandfather, Nils Samuel von Koch (1801–1881), was the Chancellor of Justice. His father, Richert Vogt von Koch (1838–1913) was a Lieutenant-Colonel in the Life Guards of Horse of the Swedish Army. He was enrolled at the newly created Stockholm University College in 1887 (studying under Gösta Mittag-Leffler), and at Uppsala University in 1888, where he also received his bachelor's degree (''filosofie kandidat'') since the non-governmental college in Stockholm had not yet received the rights to issue degrees. He received his PhD in Uppsala in 1892. He was appointed professor of mathematics at the Royal Institute of Technology in Stockholm in 1905, succeeding Ivar Bendixson, and became professor of pure mathematics at St ...

Swedish Army
The Swedish Army () is the army, land force of the Swedish Armed Forces of the Kingdom of Sweden. Beginning with its service in 1521, the Swedish Army has been active for more than 500 years. History Svea Life Guards dates back to the year 1521, when the men of Dalarna chose 16 young able men as Royal guard, body guards for the insurgent nobleman Gustav Vasa in the Swedish War of Liberation, war against the Union of Kalmar, thus making the present-day Life Guards (Sweden), Life Guards List of oldest military units and formations in continuous operation, one of the world's oldest regiments still on active duty. In 1901, Sweden introduced conscription. The conscription system was abolished in 2010 but reinstated in 2017. Organisation The peace-time organisation of the Swedish Army is divided into a number of regiments for the different branches. The number of active regiments has been reduced since the end of the Cold War in the late 1980s. However the Swedish Army has begun ...

The Plantagenet Roll Of The Blood Royal
Melville Amadeus Henry Douglas Heddle de la Caillemotte de Massue de Ruvigny (26 April 1868 – 6 October 1921) was a British genealogist and author who was twice president of the Legitimist Jacobite League of Great Britain and Ireland. He styled himself the Marquis of Ruvigny and Raineval. Biography Massue was descended from a sister of Henri de Massue, Earl of Galway, Henri de Massue de Ruvigny, a Huguenot aristocrat who emigrated to England in 1688 and became a prominent supporter of William III of England, William of Orange. He was born in London to Colonel Charles Henry Theodore Bruce de Ruvignes and Margaret Melville Moodie, the daughter of a Scottish laird. He succeeded his father as 9th Marquis of Ruvigny and 15th Marquis of Raineval in 1883, though his right to these titles was disputed by the authors of ''The Complete Peerage''. In 1893, he married Rose Amalia Gaminara, with whom he had three children. Massue was an early member of the Jacobite Order of the White Rose ...

Prime Number Theorem
In mathematics, the prime number theorem (PNT) describes the asymptotic analysis, asymptotic distribution of the prime numbers among the positive integers. It formalizes the intuitive idea that primes become less common as they become larger by precisely quantifying the rate at which this occurs. The theorem was proved independently by Jacques Hadamard and Charles Jean de la Vallée Poussin in 1896 using ideas introduced by Bernhard Riemann (in particular, the Riemann zeta function). The first such distribution found is , where is the prime-counting function (the number of primes less than or equal to ''N'') and is the natural logarithm of . This means that for large enough , the probability that a random integer not greater than is prime is very close to . Consequently, a random integer with at most digits (for large enough ) is about half as likely to be prime as a random integer with at most digits. For example, among the positive integers of at most 1000 digits, about on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riemann Hypothesis
In mathematics, the Riemann hypothesis is the conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part . Many consider it to be the most important unsolved problem in pure mathematics. It is of great interest in number theory because it implies results about the distribution of prime numbers. It was proposed by , after whom it is named. The Riemann hypothesis and some of its generalizations, along with Goldbach's conjecture and the twin prime conjecture, make up Hilbert's eighth problem in David Hilbert's list of twenty-three unsolved problems; it is also one of the Millennium Prize Problems of the Clay Mathematics Institute, which offers US$1 million for a solution to any of them. The name is also used for some closely related analogues, such as the Riemann hypothesis for curves over finite fields. The Riemann zeta function ''ζ''(''s'') is a function whose argument ''s'' may be any complex numbe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
