Václav Šimerka
Václav Šimerka (20 December 1819 – 26 December 1887) was a Czech mathematician, priest, physicist and philosopher. He wrote the first Czech text on calculus and is credited for discovering the first seven Carmichael numbers in 1885. Biography Šimerka was born on 20 December 1819 in Vysoké Veselí in Bohemia to a family of coopers of businessman Petr Šimerka and his wife Terezie. After attending school in Jičín, he studied in the University of Prague's Faculty of Philosophy from 1839 to 1841.

People From Jičín District
The term "the people" refers to the public or common mass of people of a polity. As such it is a concept of human rights law, international law as well as constitutional law, particularly used for claims of popular sovereignty. In contrast, a people is any plurality of persons considered as a whole. Used in politics and law, the term "a people" refers to the collective or community of an ethnic group or nation. Concepts Legal Chapter One, Article One of the Charter of the United Nations states that "peoples" have the right to self-determination. Though the mere status as peoples and the right to self-determination, as for example in the case of Indigenous peoples (''peoples'', as in all groups of indigenous people, not merely all indigenous persons as in ''indigenous people''), does not automatically provide for independent sovereignty and therefore secession. Indeed, judge Ivor Jennings identified the inherent problems in the right of "peoples" to self-determination, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Daniel Carmichael
Robert Daniel Carmichael (March 1, 1879 – May 2, 1967) was an American mathematician. Biography Carmichael was born in Goodwater, Alabama. He attended Lineville College, briefly, and he earned his bachelor's degree in 1898, while he was studying towards his Ph.D. degree at Princeton University. Carmichael completed the requirements for his Ph.D. in mathematics in 1911. Carmichael's Ph.D. research in mathematics was done under the guidance of the noted American mathematician G. David Birkhoff, and it is considered to be the first significant American contribution to the knowledge of differential equations in mathematics. Carmichael next taught at Indiana University from 1911 to 1915. Then he moved on to the University of Illinois, where he remained from 1915 until his retirement in 1947. Carmichael is known for his research in what are now called the Carmichael numbers (a subset of Fermat pseudoprimes, numbers satisfying properties of primes described by Fermat's Little ...

Alwin Korselt
Alwin Reinhold Korselt (17 March 1864, in Mittelherwigsdorf – 4 February 1947, in Plauen) was a German mathematician. He discovered Korselt's criterion, which provides a secondary definition for Carmichael numbers and also contributed an early result in algebraic logic. Personal life The Korselts are a huge, widespread family that has been resident in the village of Mittelherwigsdorf near Zittau in Saxony (nowadays close to the Czech and Polish borders) since the early Middle Ages. Alwin Korselt was born there in 1864. After attending '' Gymnasium'' in Zittau between 1876 and 1885, he studied mathematics and physics in Leipzig (with one semester in 1886 in Freiburg im Breisgau) until 1890. After a probationary year as a teacher at Nikolaigymnasium in Leipzig he taught from 1891 to 1898 at various schools in Pirna, Dresden, Keilhau near Rudolstadt, Löbau and Meerane. Frequent changes, often between very different school types, indicate that he found it difficult to gain groun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bruno De Finetti
Bruno de Finetti (13 June 1906 – 20 July 1985) was an Italian probabilist statistician and actuary, noted for the "operational subjective" conception of probability. The classic exposition of his distinctive theory is the 1937 , which discussed probability founded on the coherence of betting odds and the consequences of exchangeability. Life De Finetti was born in Innsbruck, Austria, and studied mathematics at Politecnico di Milano. He graduated in 1927, writing his thesis under the supervision of Giulio Vivanti. After graduation, he worked as an actuary and a statistician at ( National Institute of Statistics) in Rome and, from 1931, the Trieste insurance company Assicurazioni Generali. In 1936 he won a competition for Chair of Financial Mathematics and Statistics, but was not nominated due to a fascist law barring access to unmarried candidates; he was appointed as ordinary professor at the University of Trieste only in 1950. He published extensively (17 papers in 193 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Johann Friedrich Herbart
Johann Friedrich Herbart (; 4 May 1776 – 14 August 1841) was a German philosopher, psychologist and founder of pedagogy as an academic discipline. Herbart is now remembered amongst the post-Kantian philosophers mostly as making the greatest contrast to Hegel—in particular in relation to aesthetics. His educational philosophy is known as Herbartianism. Life Herbart was born on 4 May 1776 in Oldenburg. Growing up as a fragile child because of an unfortunate accident, Herbart was taught by his mother at home until the age of 12. He continued his schooling at the '' Gymnasium'' for six years, and showed interest in philosophy, logic and Kant's work involving the nature of knowledge obtained from experience with reality. His education then continued at Jena, whereupon he studied philosophy and came to disagree with his teacher Fichte precisely because Fichte had taught him to think in a logical manner. He composed a few essays, which he had given to Fichte during his years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algebra
Algebra is a branch of mathematics that deals with abstract systems, known as algebraic structures, and the manipulation of expressions within those systems. It is a generalization of arithmetic that introduces variables and algebraic operations other than the standard arithmetic operations, such as addition and multiplication. Elementary algebra is the main form of algebra taught in schools. It examines mathematical statements using variables for unspecified values and seeks to determine for which values the statements are true. To do so, it uses different methods of transforming equations to isolate variables. Linear algebra is a closely related field that investigates linear equations and combinations of them called '' systems of linear equations''. It provides methods to find the values that solve all equations in the system at the same time, and to study the set of these solutions. Abstract algebra studies algebraic structures, which consist of a set of mathemati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
