Gustaf Eneström
Gustaf Hjalmar Eneström (5 September 1852 – 10 June 1923) was a Swedish mathematician, statistician and historian of mathematics known for introducing the Eneström index, which is used to identify Euler's writings. Most historical scholars refer to the works of Euler by their Eneström index. Eneström received a Bachelor of Science (''filosofie kandidat'') degree from Uppsala university in 1871, received a position at Uppsala University Library in 1875, and at the National Library of Sweden in 1879. From 1884 to 1914, he was the publisher of the mathematical-historical journal ''Bibliotheca Mathematica'', which he had founded and partially funded with his own means. Concerning the history of mathematics, he was known as critical to Moritz Cantor. With Soichi Kakeya, he is known for the Eneström-Kakeya theorem which determines an annulus containing the roots of a real polynomial. In 1923 George Sarton wrote, "No one has done more for the sound development of our studies". ...

Nora, Sweden
Nora is a locality and the seat of Nora Municipality, Örebro County, Sweden with 6,526 inhabitants in 2010. History Nora received its charter in 1643. The government had requested the inhabitants of both Nora and the adjacent town Lindesberg to move together into a newly chartered city called Järle. However, the government proved unsuccessful, and instead granted both Nora and Lindesberg independent charters at that year. Many wooden houses built in the 18th and 19th century have been spared from fires and demolition, making the town Nora one of Sweden's best preserved wooden towns. Eksjö and Hjo are two other examples, and they have together with Nora initiated a wooden-town development project. Also part of the old city structure are cobbled streets with small houses and shops by small windling street. Anna Maria Lenngren, a Swedish poet, once proclaimed "Så liten stad, så mycket smak" (Such small town, so much flavor). The first normal gauge railway in Sweden was opene ...

Moritz Cantor
Moritz Benedikt Cantor (23 August 1829 – 10 April 1920) was a German historian of mathematics. Biography Cantor was born at Mannheim. He came from a Sephardi Jewish family that had emigrated to the Netherlands from Portugal Portugal, officially the Portuguese Republic ( pt, República Portuguesa, links=yes ), is a country whose mainland is located on the Iberian Peninsula of Southwestern Europe, and whose territory also includes the Atlantic archipelagos of ..., another branch of which had established itself in Russia. In his early youth, Moritz Cantor was not strong enough to go to school, and his parents decided to educate him at home. Later, however, he was admitted to an advanced class of the Gymnasium in Mannheim. From there he went to the University of Heidelberg in 1848, and soon after to the University of Göttingen, where he studied under Carl Friedrich Gauss, Gauss and Heinrich Martin Weber, Weber, and where Stern awakened in him a strong interest in histor ...

Uppsala University Alumni
Uppsala (, or all ending in , ; archaically spelled ''Upsala'') is the county seat of Uppsala County and the fourth-largest city in Sweden, after Stockholm, Gothenburg, and Malmö. It had 177,074 inhabitants in 2019. Located north of the capital Stockholm it is also the seat of Uppsala Municipality. Since 1164, Uppsala has been the ecclesiastical centre of Sweden, being the seat of the Archbishop of the Church of Sweden. Uppsala is home to Scandinavia's largest cathedral – Uppsala Cathedral, which was the frequent site of the coronation of the Swedish monarch until the late 19th century. Uppsala Castle, built by King Gustav Vasa, served as one of the royal residences of the Swedish monarchs, and was expanded several times over its history, making Uppsala the secondary capital of Sweden during its greatest extent. Today it serves as the residence of the Governor of Uppsala County. Founded in 1477, Uppsala University is the oldest centre of higher education in Scandinavi ...

Historians Of Mathematics
The history of mathematics deals with the origin of discoveries in mathematics and the mathematical methods and notation of the past. Before the modern age and the worldwide spread of knowledge, written examples of new mathematical developments have come to light only in a few locales. From 3000 BC the Mesopotamian states of Sumer, Akkad and Assyria, followed closely by Ancient Egypt and the Levantine state of Ebla began using arithmetic, algebra and geometry for purposes of taxation, commerce, trade and also in the patterns in nature, the field of astronomy and to record time and formulate calendars. The earliest mathematical texts available are from Mesopotamia and Egypt – ''Plimpton 322'' ( Babylonian c. 2000 – 1900 BC), the '' Rhind Mathematical Papyrus'' (Egyptian c. 1800 BC) and the ''Moscow Mathematical Papyrus'' (Egyptian c. 1890 BC). All of these texts mention the so-called Pythagorean triples, so, by inference, the Pythagorean theorem seems to be the most ancient a ...

George Sarton
George Alfred Leon Sarton (; 31 August 1884 – 22 March 1956) was a Belgian-born American chemist and historian. He is considered the founder of the discipline of the history of science as an independent field of study. His most influential works were the ''Introduction to the History of Science'', which consists of three volumes and 4,296 pages and the journal ''Isis''. Sarton ultimately aimed to achieve an integrated philosophy of science that provided a connection between the sciences and the humanities, which he referred to as "the new humanism". Sarton's life and work George Alfred Leon Sarton was born to Léonie Van Halmé and Alfred Sarton on August 31, 1884 in Ghent, East Flanders, Belgium. However, within a year of his birth, Sarton's mother died. He attended school first in his hometown before later attending school for a period of four years in the town of Chimay. Sarton enrolled at the University of Ghent in 1902 to study philosophy, but found that the subject did not ...

Polynomial
In mathematics, a polynomial is an expression consisting of indeterminates (also called variables) and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables. An example of a polynomial of a single indeterminate is . An example with three indeterminates is . Polynomials appear in many areas of mathematics and science. For example, they are used to form polynomial equations, which encode a wide range of problems, from elementary word problems to complicated scientific problems; they are used to define polynomial functions, which appear in settings ranging from basic chemistry and physics to economics and social science; they are used in calculus and numerical analysis to approximate other functions. In advanced mathematics, polynomials are used to construct polynomial rings and algebraic varieties, which are central concepts in algebra and algebraic geometry. Etymology The word ''polynomial'' join ...

Annulus (mathematics)
In mathematics, an annulus (plural annuli or annuluses) is the region between two concentric circles. Informally, it is shaped like a ring or a hardware washer. The word "annulus" is borrowed from the Latin word ''anulus'' or ''annulus'' meaning 'little ring'. The adjectival form is annular (as in annular eclipse). The open annulus is topologically equivalent to both the open cylinder and the punctured plane. Area The area of an annulus is the difference in the areas of the larger circle of radius and the smaller one of radius : :A = \pi R^2 - \pi r^2 = \pi\left(R^2 - r^2\right). The area of an annulus is determined by the length of the longest line segment within the annulus, which is the chord tangent to the inner circle, in the accompanying diagram. That can be shown using the Pythagorean theorem since this line is tangent to the smaller circle and perpendicular to its radius at that point, so and are sides of a right-angled triangle with hypotenuse , and the ar ...
