Willem Van Der Woude
Willem van der Woude (15 January 1876 – 23 September 1974) was a Dutch mathematician and ''rector magnificus'' (chancellor) of the University of Leiden. Education and career Van der Woude studied at the University of Groningen, and subsequently, from 1901 to 1916, worked as a secondary school teacher in Deventer. In 1908 he received his Ph.D. from the University of Groningen under Pieter Hendrik Schoute with a thesis titled ''Over elkaar snijdende normalen aan een ellipsoide en een hyperellipsoide'' (On intersecting normals to an ellipsoid An ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation. An ellipsoid is a quadric surface; that is, a surface that may be defined as the ... and a hyperellipsoid).

Pieter Hendrik Schoute
Pieter Hendrik Schoute (21 January 1846, Wormerveer – 18 April 1913, Groningen) was a Dutch mathematician known for his work on regular polytopes and Euclidean geometry. He started his career as a civil engineer, but became a professor of mathematics at Groningen and published some thirty papers on polytopes between 1878 and his death in 1913. He collaborated with Alicia Boole Stott on describing the sections of the regular 4-polytopes. In 1886, he became member of the Royal Netherlands Academy of Arts and Sciences The Royal Netherlands Academy of Arts and Sciences ( nl, Koninklijke Nederlandse Akademie van Wetenschappen, abbreviated: KNAW) is an organization dedicated to the advancement of science and literature in the Netherlands.

People From Dongeradeel
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form " people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural ...

Academic Staff Of Leiden University
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of secondary or tertiary higher learning (and generally also research or honorary membership). The name traces back to Plato's school of philosophy, founded approximately 385 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and skill, north of Athens, Greece. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive grove, hence the expression "the groves of Academe". In these gardens, the philosopher Plato conversed with followers. Plato developed his sessions into a method of teaching philosophy and in 387 BC, established what is known today as the Old Academy. By extension, ''academia'' has come to mean the accumulation, dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Berend George Escher
Berend George Escher (4 April 1885 – 11 October 1967) was a Dutch geologist. Escher had a broad interest, but his research was mainly on crystallography, mineralogy and volcanology. He was a pioneer in experimental geology. He was a half-brother of the artist Maurits Cornelis Escher, M.C. Escher, and had some influence on his work due to his knowledge of crystallography. M.C. Escher created a woodcut ''ex libris'' for his brother 'Beer' with a stylized image of a volcano around 1922 (Bool number 91). Escher was the son of the civil engineer George Arnold Escher, G. A. Escher, a director of the Dutch watermanagement (''Rijkswaterstaat'') and his first wife, Charlotte Marie Hartitzsch. Escher spent his youth in Switzerland. He studied geology at the ETH Zurich, Eidgenössische Technische Hochschule (Technical University) of Zürich, where he was a pupil of Albert Heim. He finished his studies in 1911 and returned to the Netherlands where he first became the assistant of Eugèn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Dutch Mathematical Society
The Royal Dutch Mathematical Society (Koninklijk Wiskundig Genootschap in Dutch, abbreviated as KWG) was founded in 1778. Its goal is to promote the development of mathematics, both from a theoretical and applied point of view. The society publishes the quarterly journal ''Nieuw Archief voor Wiskunde'', the magazine ''Pythagoras, wiskundetijdschrift voor jongeren'' for high school children, and the scientific journal ''Indagationes Mathematicae''. Each year the society organizes a winter symposium for high school teachers. Biannually Koninklijk Wiskundig Genootschap organizes the Dutch Mathematical Congress. Once every three years, the society awards the prestigious Brouwer Medal to a distinguished mathematician. This medal is named after L. E. J. Brouwer. Honorary members Institutional members The society has the following institutional members: * Centrum Wiskunde & Informatica * Delft University of Technology * Eindhoven University of Technology * Leiden University * ...

List Of International Congresses Of Mathematicians Plenary And Invited Speakers
This is a list of International Congresses of Mathematicians Plenary and Invited Speakers. Being invited to talk at an International Congress of Mathematicians has been called "the equivalent, in this community, of an induction to a hall of fame." The current list of Plenary and Invited Speakers presented here is based on the ICM's post-WW II terminology, in which the one-hour speakers in the morning sessions are called "Plenary Speakers" and the other speakers (in the afternoon sessions) whose talks are included in the ICM published proceedings are called "Invited Speakers". In the pre-WW II congresses the Plenary Speakers were called "Invited Speakers". By congress year 1897, Zürich * Jules Andrade * Léon Autonne *Émile Borel * N. V.

Ellipsoid
An ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation. An ellipsoid is a quadric surface; that is, a surface that may be defined as the zero set of a polynomial of degree two in three variables. Among quadric surfaces, an ellipsoid is characterized by either of the two following properties. Every planar cross section is either an ellipse, or is empty, or is reduced to a single point (this explains the name, meaning "ellipse-like"). It is bounded, which means that it may be enclosed in a sufficiently large sphere. An ellipsoid has three pairwise perpendicular axes of symmetry which intersect at a center of symmetry, called the center of the ellipsoid. The line segments that are delimited on the axes of symmetry by the ellipsoid are called the ''principal axes'', or simply axes of the ellipsoid. If the three axes have different lengths, the figure is a triaxial ellipsoid (r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deventer
Deventer (; Sallands: ) is a city and municipality in the Salland historical region of the province of Overijssel, Netherlands. In 2020, Deventer had a population of 100,913. The city is largely situated on the east bank of the river IJssel, but it also has a small part of its territory on the west bank. In 2005 the municipality of Bathmen (with a population of about 5,000 people) was merged with Deventer as part of a national effort to reduce bureaucracy in the country. Deventer is one of the oldest cities in the Netherlands. The place is already mentioned in 9th-century sources of the Diocese of Utrecht. In a charter from 877 AD mentions seven hooves in ''Daventre portu'' (the Deventer harbor). In 952 AD, Deventer is mentioned as a city in a gift certificate from King Otto I. After the place had acquired more and more rights and privileges over time, it received the municipal lands from Emperor Henry V in 1123. This is considered by historians to be the moment of Deventer o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
