https://en.wikipedia.org/wiki/Oskar%20van%20Deventer | Oskar van Deventer (born 1965) is a Dutch puzzle maker. He prototypes puzzles using 3D printing. His work combines mathematics, physics, and design, and he collaborates at academic institutions. Many of his combination puzzles are in mass production by Uwe Mèffert and WitEden. Oskar van Deventer has also designed puzzles for Hanayama.
He was a Guinness World Record holder for his 17×17×17 "Over the Top Cube" Rubik's cube-style puzzle from 2012 to 2016, when it was beaten by a 22×22×22 cube.
In addition to being a puzzle maker, Oskar is a research scientist in the area of media networking and holds a Ph.D. in optics. He has over 100 publications, over 80 patents applications, and hundreds of standardization contributions.
Mass-produced puzzles
Gear cube: Previously named "Caution Cube" because there was a big chance to pinch your fingers with the gears. It was mass-produced by Mèffert's in 2010, but over time it appeared as several copies and shape mods of the same design.
Gear Cube Extreme: A bandaged version of the Gear cube, where 4 gears are replaced with 4 standard edges, making the puzzle harder. It was mass-produced by Mèffert's in 2010, and was also copied by other companies.
Gear Shift: It was mass-produced by Mèffert's in 2011; a knock off version also appeared.
David Gear Cube: Previously called "Polo cube" in reference to Alex Polonsky, who had the idea. It was mass-produced By Mèffert's in 2013.
Geared Mixup: A variant of the gear cube where all faces can perform 90° rotations, allowing centers to be interchanged with edges, hence the term "mixup". It was mass-produced by Mèffert's in 2014.
Geared 5×5×5: An unknown Chinese company mass-produced this puzzle in 2015 using a 3D printed sample, without the permission of Oskar. An agreement was met to please both sides.
Gear Ball: A mass-produced spherical Gear cube made by Mèffert's.
Mosaic cube: Previously called "Fadi cube", it is a corner turning puzzle with two cut depths similar to Okamoto and Greg's "Lattice Cube". It was mass-produced by Mèffert's in 2010.
Planets puzzle: Four balls in a frame. Craters on the balls block and unblock movement on the adjacent balls.
Rob's Pyraminx: It was mass-produced by Mèffert's in 2014.
Rob's Octahedron: It was mass-produced by Mèffert's in 2015.
Mixup Cube: a 3×3×3 Rubik's cube that can perform 45° rotations on the middle layers, allowing centers interchange with edges. It was mass-produced by WitEden.
Treasure chest: A 3×3×3 puzzle that when solved, can be opened, revealing a small chamber inside. It was mass-produced by Mèffert's.
Icosaix: A face turning icosahedron with jumbling movements. It was mass-produced by MF8 in 2015.
Crazy Comet: Was mass-produced by LanLan without Oskar's permission in 2016 but a deal was archived later.
Redi Cube: A corner turning puzzle mass produced by Moyu in 2017.

https://en.wikipedia.org/wiki/Joseph%20Gillis | Joseph E. Gillis (3 August 1911 – 18 November 1993) was a British-Israeli mathematician and one of the founders of the Faculty of Mathematics at the Weizmann Institute of Science, where he served as a Professor of Applied Mathematics. He made notable contributions to fractal sets, fluid dynamics, random walks, and pioneered the combinatorial theory of special functions of mathematical physics.
Career
Gillis was born on 3 August 1911 in Sunderland, in the north east of England. He studied at Trinity College, Cambridge, completing his doctoral thesis on "Some Geometrical Properties of Linearly Measurable Plane Sets of Points" under A.S. Besicovitch in 1935. During World War II he worked in Bletchley Park as a cryptographer. He taught maths at Queen's University Belfast between 1937 and 1947.
In 1948 he immigrated to Israel and joined the Weizmann Institute of Science (then the Ziv Institute), where he, along with others, founded the Department of Applied Mathematics. He also served as the Academic Secretary. During the Academic Year 1954-1955 he visited the Institute for Advanced Study as part of the Electronic Computer Project headed by John von Neumann. He was very active in advancing mathematics education, and chaired the department of Science Teaching at the Weizmann Institute. He also started the Israel Mathematics Olympiad and coached the Israeli team for many years, as well as edited mathematics periodicals for high school students and amateurs.
Personal life
He was married to Olga Kirsch and had two daughters. He died on 18 November 1993.

https://en.wikipedia.org/wiki/Gunther%20Schmidt | Gunther Schmidt (born 1939, Rüdersdorf) is a German mathematician who works also in informatics.
Life
Schmidt began studying Mathematics in 1957 at Göttingen University. His academic teachers were in particular Kurt Reidemeister, Wilhelm Klingenberg and Karl Stein. In 1960 he transferred to Ludwig-Maximilians-Universität München where he studied functions of several complex variables with Karl Stein. Schmidt wrote a thesis on analytic continuation of such functions.
In 1962 Schmidt began work at TU München with students of Robert Sauer, in the beginning in labs and tutorials, later in mentoring and administration. Schmidt's interests turned toward programming when he collaborated with Hans Langmaack on rewriting and the braid group in 1969. Friedrich L. Bauer and Klaus Samelson were establishing software engineering at the university and Schmidt joined their group in 1974. In 1977 he submitted his Habilitation "Programs as partial graphs".
He became a professor in 1980. Shortly after that, he was appointed to hold the chair of the late Klaus Samelson for one and a half years. From 1988 until his retirement in 2004, he held a professorship at the Faculty for Computer Science of the Universität der Bundeswehr München. He was a classroom instructor for beginners courses as well as special courses in mathematical logic, semantics of programming languages, construction of compilers, and algorithmic languages. Working with Thomas Strohlein, he authored a textbook on relations and graphs, published in German in 1989 and English in 1993 and again in 2012.
In 2001 he became involved in a large project (17 nations) with the European Cooperation in Science and Technology: Schmidt was chairman of project COST 274 TARSKI (Theory and Application of Relational Structures as Knowledge Instruments).
In 2014 a festschrift was organized to celebrate his 75th year.
The calculus of relations had a relatively low profile among mathematical topics in the twentieth century, but Schmidt and others have raised that profile. The partial order of binary relations can be organized by grouping through closure. In 2018 Schmidt and Michael Winter published Relational Topology which reviews classical mathematical structures, such as binary operations and topological space, through the lens of calculus of relations.
Work
In 1981 he participated in the International Summer School Marktoberdorf, and edited the lecture notes Theoretical Foundations of Programming Methodology with Manfred Broy.
Gunther Schmidt is mainly known for his work on Relational Mathematics; he was co-founder of the RAMiCS conference series in 1994.
His textbooks on calculus of relations exhibit applications and potential of algebraic logic.

https://en.wikipedia.org/wiki/Stephen%20Skinner%20%28author%29 | Stephen Skinner (born 22 March 1948) is an Australian author, editor, publisher and lecturer. He is known for authoring books on magic, feng shui, sacred geometry and alchemy. He has published more than 46 books in more than 20 languages.
Early life and education
Born in Sydney, Australia in March 1948, he lived there till 1972. He attended Trinity Grammar Preparatory School (Strathfield) and Sydney Grammar Secondary School from 1959 to 1964, matriculating with First Class Honors in English, and honors in Geography. He earned his BA (Arts) at Sydney University from 1965 to 1968, majoring in English Literature and Geography, plus Philosophy (Greek Philosophy and formal Logic).
In 1967 he launched and edited two underground magazines in Sydney, titled Lucifer and Chaos. He worked for one year in the Intelligence section of the Department of Trade & Industry (1969), before an interest in the stock market lead to working full-time as a portfolio manager. From there he moved to teaching as a Geography Master at St. Joseph's College, Hunters Hill, Sydney (1970), followed by Geography Lecturer at Sydney Technical College (now called the University of Technology) in 1971–72.
He received his Ph.D. in classics from the School of Humanities and Social Science, University of Newcastle in 2014 for a thesis on the transmission of magical techniques and equipment from the Graeco-Egyptian magical papyri (1st-5th century C.E.) via the Byzantine Magical Treatise of Solomon (Hygromanteia) to the 16th-18th century grimoires of Western Europe, specifically the Clavicula Salomonis. The thesis was later developed into two books: Techniques of Graeco-Egyptian Magic and Techniques of Solomonic Magic.
Career
He migrated to London in December 1972, where his career alternated between book and magazine publishing and computer programming. In 1973, he founded Askin Publishers Ltd, and became its managing director, in order to print editions of the magical writings of Dr. John Dee, Cornelius Agrippa, Paracelsus, Austin Osman Spare and Aleister Crowley. In 1976 he helped in the production of the Crowley Thoth Tarot card pack by arranging the re-photography of the original paintings in the Warburg Institute, which were later used in the revised edition published by U.S. Games Inc in that year.
In 1998 he launched and published Feng Shui for Modern Living magazine. Skinner organised and ran the London International Feng Shui Conference (co-sponsored by the Daily Express newspaper) at the Islington Exhibition Centre, London on 21–23 May 1999. In 2000, he was nominated for Publisher of the Year at the PPA Awards in London for the magazine Feng Shui for Modern Living.
Before leaving London, Skinner founded Golden Hoard Press Pte. Ltd, a book publishing company specializing in the publication of the classics of magic and feng shui, and began publishing the Source Works of Ceremonial Magic series with co-author David Rankine.
In 2003 he migrated to Johor Bahru in Malaysia, t |

https://en.wikipedia.org/wiki/Localizing%20subcategory | In mathematics, Serre and localizing subcategories form important classes of subcategories of an abelian category. Localizing subcategories are certain Serre subcategories. They are strongly linked to the notion of a quotient category.
Serre subcategories
Let be an abelian category. A non-empty full subcategory is called a Serre subcategory (or also a dense subcategory), if for every short exact sequence in the object is in if and only if the objects
and belong to . In words: is closed under subobjects, quotient objects
and extensions.
Each Serre subcategory of is itself an abelian category, and the inclusion functor is exact. The importance of this notion stems from the fact that kernels of exact functors between abelian categories are Serre subcategories, and that one can build (for locally small ) the quotient category (in the sense of Gabriel, Grothendieck, Serre) , which has the same objects as , is abelian, and comes with an exact functor (called the quotient functor) whose kernel is .
Localizing subcategories
Let be locally small. The Serre subcategory is called localizing if the quotient functor
has a
right adjoint
. Since then , as a left adjoint, preserves colimits, each localizing subcategory is closed under colimits. The functor (or sometimes ) is also called the localization functor, and the section functor. The section functor is left-exact and fully faithful.
If the abelian category is moreover
cocomplete and has injective hulls (e.g. if it is a Grothendieck category), then a Serre
subcategory is localizing if and only if
is closed under arbitrary coproducts (a.k.a.
direct sums). Hence the notion of a localizing subcategory is
equivalent to the notion of a hereditary torsion class.
If is a Grothendieck category and a localizing subcategory, then and the quotient category
are again Grothendieck categories.
The Gabriel-Popescu theorem implies that every Grothendieck category is the quotient category of a module category (with a suitable ring) modulo a localizing subcategory.

https://en.wikipedia.org/wiki/Quantization%20commutes%20with%20reduction | In mathematics, more specifically in the context of geometric quantization, quantization commutes with reduction states that the space of global sections of a line bundle L satisfying the quantization condition on the symplectic quotient of a compact symplectic manifold is the space of invariant sections of L.
This was conjectured in 1980s by Guillemin and Sternberg and was proven in 1990s by Meinrenken (the second paper used symplectic cut) as well as Tian and Zhang. For the formulation due to Teleman, see C. Woodward's notes.

It was formed in 1993 by a group of French newspaper syndicates:
Presse quotidienne régionale ("Daily regional press")
Presse quotidienne nationale ("Daily national press")
Presse quotidienne urbaine gratuite ("Daily metropolitan free press")
Presse hebdomadaire régionale ("Weekly regional press")
It conducts its research using computer-assisted telephone interviewing (CATI), for both daily and weekly newspapers. Research is conducted on its behalf by other market research organisations, notably TNS Sofres.

https://en.wikipedia.org/wiki/Flow%20graph%20%28mathematics%29 | A flow graph is a form of digraph associated with a set of linear algebraic or differential equations:
"A signal flow graph is a network of nodes (or points) interconnected by directed branches, representing a set of linear algebraic equations. The nodes in a flow graph are used to represent the variables, or parameters, and the connecting branches represent the coefficients relating these variables to one another. The flow graph is associated with a number of simple rules which enable every possible solution [related to the equations] to be obtained."
Although this definition uses the terms "signal-flow graph" and "flow graph" interchangeably, the term "signal-flow graph" is most often used to designate the Mason signal-flow graph, Mason being the originator of this terminology in his work on electrical networks. Likewise, some authors use the term "flow graph" to refer strictly to the Coates flow graph. According to Henley & Williams:
"The nomenclature is far from standardized, and...no standardization can be expected in the foreseeable future."
A designation "flow graph" that includes both the Mason graph and the Coates graph, and a variety of other forms of such graphs appears useful, and agrees with Abrahams and Coverley's and with Henley and Williams' approach.
A directed network – also known as a flow network – is a particular type of flow graph. A network is a graph with real numbers associated with each of its edges, and if the graph is a digraph, the result is a directed network. A flow graph is more general than a directed network, in that the edges may be associated with gains, branch gains or transmittances, or even functions of the Laplace operator s, in which case they are called transfer functions.
There is a close relationship between graphs and matrices and between digraphs and matrices. "The algebraic theory of matrices can be brought to bear on graph theory to obtain results elegantly", and conversely, graph-theoretic approaches based upon flow graphs are used for the solution of linear algebraic equations.
Deriving a flow graph from equations
An example of a flow graph connected to some starting equations is presented.
The set of equations should be consistent and linearly independent. An example of such a set is:
Consistency and independence of the equations in the set is established because the determinant of coefficients is non-zero, so a solution can be found using Cramer's rule.
Using the examples from the subsection Elements of signal-flow graphs, we construct the graph In the figure, a signal-flow graph in this case. To check that the graph does represent the equations given, go to node x1. Look at the arrows incoming to this node (colored green for emphasis) and the weights attached to them. The equation for x1 is satisfied by equating it to the sum of the nodes attached to the incoming arrows multiplied by the weights attached to these arrows. Likewise, the red arrows and their weights provide the equation |

https://en.wikipedia.org/wiki/M.%20Salah%20Baouendi | Mohammed Salah Baouendi (; October 12, 1937 in Tunis – December 24, 2011 in La Jolla, California) was a Tunisian-American mathematician who worked as a Distinguished Professor of Mathematics at the University of California, San Diego. His research concerned partial differential equations and the theory of several complex variables.
Education and career
Baouendi moved from Tunis to France after finishing his Baccalauréat in the high school Sadiki College , and earned a licence (a French undergraduate degree) in 1961 from the Sorbonne. In this he had the assistance of a scholarship from the Tunisian government, which however demanded that he return to Tunis afterwards to become a schoolteacher. After the intervention of Laurent Schwartz, Baouendi was allowed to return to France for his graduate studies. He completed a doctorate in 1967 from the University of Paris-Sud (then part of the University of Paris), under the supervision of Bernard Malgrange, with a dissertation concerning elliptic operators. Schwartz attempted to secure for him a suitable academic position in Tunis, in which he would be allowed to conduct research and collaborate with mathematicians from other countries, and Baouendi became an associate professor at Tunis University in 1968, but his administrative struggles there were too much, and he left in 1970. After a short stay at the University of Nice, Baouendi moved in 1971 to the USA.
Baouendi's first American faculty position was at Purdue University. During his tenure at Purdue, he was promoted to full professor in 1973, became department chair from 1980 to 1987, and also held visiting positions at Pierre and Marie Curie University, the University of Chicago, and Rutgers University. He became a Distinguished Professor at UCSD in 1988 (giving up his Purdue professorship in 1990). He was a co-founder of two journals, Communications in Partial Differential Equations and Mathematical Research Letters.
Awards and honors
Baouendi was given the Prix d'Aumale of the French Academy of Sciences in 1969. He was an invited speaker at the International Congress of Mathematicians in 1974. He and his wife, mathematician Linda Preiss Rothschild, were jointly awarded the Stefan Bergman Prize of the American Mathematical Society in 2003. In 2005 he became a fellow of the American Academy of Arts and Sciences.

https://en.wikipedia.org/wiki/Radovan%20Brenkus | Radovan Brenkus (born 30 January 1974, Bardejov) is a Slovak writer, translator and critic.
Biography
The author finished the study at Science faculty of P. J. Šafárik University, in mathematics and physics. He worked as a teacher in Košice, later as a specialist worker at the Institute of Experimental Physics of Slovak Academy of Sciences. He publishes in journals at home and abroad. Slovak Radio broadcast a lot of his works, which have been published in international anthologies. He translates works from Polish and occasionally undertakes literary criticism, writing a critical studies and essays. The author works in publishing house Pectus in Košice, which was founded in 2006.
Creation
Brenkus is a continuator of literary modernism. In the field of poetry, he observes, analyses and decrypts the chaotic tired world, denounces the prevailing moral circumstances, the differences in its perception from without and within. The inspiratory sources are destructive emptiness, nothingness, limiting pseudo-being. By a symbology of pessimism and decadence, he shows the loneliness of the individual, his more worsening condition and uncertain future.
The motive of his prose is a search for the meaning of existence, awareness of transience, death. Among other things, Brenkus writes in neo-romantic style, as well as criticizes existentialism and the civilization progress which forces a human to find his own survival instinct. Surrealistic characters in author's stories are torn between the ideal and the real, and disturb an accepted order. Through expressive and mystical symbolism, dramatic and grotesque scenes, Brenkus displays rebellion against elitism and decline of contemporary society. He provides a space for catharsis in the condensed and equally distinctive characteristics of the situations and characters.

https://en.wikipedia.org/wiki/Jan%20Willem%20Nienhuys | Jan Willem Nienhuys (born 16 April 1942) is a Dutch mathematician, book translator and skeptic. He taught mathematics at the Eindhoven University of Technology. He is also a board member and secretary of Stichting Skepsis and an editor of its magazine Skepter.
Biography
Nienhuys studied mathematics in the Netherlands, and in 1966/67 at Tulane University in New Orleans, where he met his future wife. On 14 September 1970, he earned his doctorate in mathematics at Utrecht University under guidance of his promotor Hans Freudenthal. His dissertation was published the same year in the journal Indagationes Mathematicae (Proceedings). He then taught mathematics for two years at the National Taiwan University in Taipei, Taiwan. Since 1973, Nienhuys taught mathematics at the Eindhoven University of Technology. He also assisted several writers in completing their books, and translated books to Dutch.
Nienhuys married and had two sons with Cheng Shan-Hwei. Born in Sichuan during the Second Sino-Japanese War, she was raised in Taiwan where she also studied mathematics, finishing her studies in the United States. She went on to teach informatics at the Erasmus University Rotterdam and become the director of the Chinese School Eindhoven. The couple published an article together in 1979, Onwaar versus onzinnig in the Dutch journal Euclides, and co-authored a book about China, China: Geschiedenis, Cultuur, Wetenschap, Kunst En Politiek (2007).
Skepticism
Nienhuys is a prolific skeptic. Amongst other things he has written several articles on pseudoscience, mainly about quackery such as homeopathy and the anti-vaccination movement. Since the late 1980s he has served as a board member, and since 2003 secretary of, Stichting Skepsis. Nienhuys also writes articles as an editorial staff member of the magazine Skepter. From July 2008 until 6 November 2010, he was editor-in-chief of the Vereniging tegen de Kwakzalverij website.
In 1983, Nienhuys criticised the confluence model of Robert B. Zajonc and Gregory B. Markus. This mathematical model would serve as proof that a connection existed between the order of birth and intelligence to the advantage of the firstborn, as Lillian Belmont and Francis A. Marolla concluded in 1973 from a registration of the Dutch armed forces. This record consisted of the data of nearly 400,000 19-year-old men born in the period 1944–1947, originally collected to investigate the effects of the Hunger Winter (1944–1945) on mental and physical development. According to Nienhuys, Zajonc and Markus's model contained errors in the logic, calculations and methodology used.
Since 2010, Nienhuys has been a fellow of the Committee for Skeptical Inquiry. He often lectures at skeptical conferences such as Skepsis congresses and SKEPP conventions. On 4 October 2014, Nienhuys received the Gebroeders Bruinsma Erepenning, an award of the Vereniging tegen de Kwakzalverij. The society praised Nienhuys for his "enormous engagement, an amazing ability to |

https://en.wikipedia.org/wiki/Ray%20class%20field | In mathematics, a ray class field is an abelian extension of a global field associated with a ray class group of ideal classes or idele classes. Every finite abelian extension of a number field is contained in one of its ray class fields.
The term "ray class group" is a translation of the German term "Strahlklassengruppe". Here "Strahl" is German for ray, and often means the positive real line, which appears in the positivity conditions defining ray class groups. uses "Strahl" to mean a certain group of ideals defined using positivity conditions, and uses "Strahlklasse" to mean a coset of this group.
There are two slightly different notions of what a ray class field is, as authors differ in how the infinite primes are treated.
History
Weber introduced ray class groups in 1897. Takagi proved the existence of the corresponding ray class fields in about 1920. Chevalley reformulated the definition of ray class groups in terms of ideles in 1933.
Ray class fields using ideals
If m is an ideal of the ring of integers of a number field K and S is a subset of the real places, then the ray class group of m and S is the quotient group
where Im is the group of fractional ideals co-prime to m, and the "ray" Pm is the group of principal ideals generated by elements a with a ≡ 1 mod m that are positive at the places of S.
When S consists of all real places, so that a is restricted to be totally positive, the group is called the narrow ray class group of m. Some authors use the term "ray class group" to mean "narrow ray class group".
A ray class field of K is the abelian extension of K associated to a ray class group by class field theory, and its Galois group is isomorphic to the corresponding ray class group. The proof of existence of a ray class field of a given ray class group is long and indirect and there is in general no known easy way to construct it (though explicit constructions are known in some special cases such as imaginary quadratic fields).
Ray class fields using ideles
Chevalley redefined the ray class group of an ideal m and a set S of real places as the quotient of the idele class group by image of the group
where Up is given by:
The nonzero complex numbers for a complex place p
The positive real numbers for a real place p in S, and all nonzero real numbers for p not in S
The units of Kp for a finite place p not dividing m
The units of Kp congruent to 1 mod pn if pn is the maximal power of p dividing m.
Some authors use a more general definition, where the group Up is allowed to be all nonzero real numbers for certain real places p.
The ray class groups defined using ideles are naturally isomorphic to those defined using ideals. They are sometimes easier to handle theoretically because they are all quotients of a single group, and thus easier to compare.
The ray class field of a ray class group is the (unique) abelian extension L of K such that the norm of the idele class group CL of L is the image of in the idele clas |
https://en.wikipedia.org/wiki/Krishnaswami%20Alladi | Krishnaswami Alladi (born October 5, 1955) is an Indian-American mathematician who specializes in number theory. He works as a professor of mathematics at the University of Florida, and was chair of the mathematics department there from 1998 to 2008. He is also the editor-in-chief of The Ramanujan Journal (published by Springer), which he founded in 1997.
Alladi was born in Thiruvananthapuram, and did his undergraduate studies at the University of Madras, graduating in 1975. While still an undergraduate, he wrote to Paul Erdős concerning his research on the function that maps each integer to the sum of its prime factors (with repetition); Erdős came to Madras to meet him, and their collaboration on this subject became Alladi's first paper; the two mathematicians coauthored 5 papers in total. He earned his Ph.D. from the University of California, Los Angeles in 1978 under the supervision of Ernst G. Straus. After visiting the University of Michigan, the Institute for Advanced Study, and the University of Hawaiʻi, he became an associate professor in 1981 at the Institute of Mathematical Sciences, Chennai, which had been founded by his father Alladi Ramakrishnan. He moved to the University of Florida in 1986.
In 2012, he became one of the inaugural fellows of the American Mathematical Society.

https://en.wikipedia.org/wiki/Erable | Erable is a computer algebra system (CAS) for a family of Hewlett-Packard graphing scientific calculators of the HP 40, 48 and HP 49/50 series.
History
Originally named ALGB in 1993, it was developed by the French mathematician for the HP 48SX. Over time, the system integrated a lot of functionality from another math pack for the HP 48 series, ALG48 by Mika Heiskanen and Claude-Nicolas Fiechter. At some point, ALGB was renamed into Erable, a French play-on-words on another CAS named Maple. Compatible with the HP 48S, 48SX, 48G, 48G+, 48GX, Erable became one of the "must-have" software packages to be installed by advanced users of these calculators.
When Hewlett-Packard developed the HP 49G in 1999, the Erable and ALG48 packages became an integral part of the calculator's firmware, now just named HP49 CAS.
As HP CAS it also showed up in the HP 40G, 40gs, 49g+, 48gII and 50g and was maintained by Parisse up to 2006.
Based on his experiences with Erable, Parisse started developing a new and more general CAS system named Xcas / Giac in 2000. It is written in C++ rather than System RPL. This system was integrated into the HP Prime in 2013 under a dual-license scheme.
Versions
The last stable stand-alone version of Erable for the HP 48 series is 3.024 (1998-08-06), with source code as of 1998-07-14 available under the GNU GPL. The latest beta versions for these calculators are 3.117 (1998-10-17) and 3.201 (1999-02-07).
Parts of the CAS system for the HP 49/50 series (version 4) were released as open-source under the LGPL (since some parts of the CAS, which are copyrighted by Hewlett-Packard, remain proprietary software) and were maintained by Parisse up to 2006-02-02 (for firmware 2.14), and 2006-09-19 (for firmware 2.15 (2009-04-21) and 2.16 (2012-04-26)).

https://en.wikipedia.org/wiki/Paul%20Friedlander%20%28artist%29 | Paul Friedlander (born 1951) is a light artist who first trained as a physicist. Friedlander obtained a bachelor's degree in Physics and Mathematics at the University of Sussex and was tutored by Sir Anthony Leggett who later was awarded a Nobel Prize for his work on superfluidity. In 1976 he graduated with a B.A. in Fine Art at Exeter College of Art, UK. Friedlander worked as a lighting and stage designer for theatrical productions and avant-garde music before devoting himself to kinetic art at the age of 36. He lives and works in London, United Kingdom (UK).
Early life
Friedlander was born in Manchester, UK, and his family moved to Cambridge when he was three. His father, F. Gerard Friedlander (1917-2001), was the son of Elfriede and . He was a lecturer and reader of mathematics at the University of Cambridge and later made a fellow of the Royal Society. Friedlander's mother, Yolande Friedlander, was an abstract artist. His parents were non-conformist and encouraged Paul to follow his own inclinations. As a child Friedlander was inspired by the space age and dreamed of building his own interstellar spaceships.
Artwork
Paul Friedlander became fascinated by art involving the use of movement and light in the late 1960s, when he visited the Cybernetic Serendipity exhibition at the Institute of Contemporary Arts and the Kinetics show at the Hayward Gallery. He was most inspired by the works of the cybernetic artists Nicolas Schöffer (1912) and Wen-Ying Tsai (1928). Since then he has been strongly driven to make kinetic works. In 1983 he made an important discovery of the chaotic properties of spinning string and invented chromastrobic light 'light that changes color faster than the human eye can see'.
These innovations became a major foundation for many of his later works. His first sculptures to use chromastrobic light were exhibited in the same year at London's ICA gallery.
Initially Friedlander started experimenting with small sculptures which over the years have increased in size as he technically improved the designs and created more complex systems. The chromastrobic lighting system itself was custom built by Friedlander as there were no other light sources that could produce this light. In recent years he developed ways of modifying standard LED lights, however this has only been possible since around 2000s. His biggest work to date at 15 meters tall was commissioned to be displayed for 'Milan Design Week 2006' in the Porta Ticinese gate.
Many of his works make use of persistence of vision, a property of how light is perceived combined with movement to create a three dimensional kinetic body of light in sculptural form. Friedlander applies his scientific knowledge to his art and is heavily influenced by chaos theory, string theory and cosmology.
In 1991, a mass-produced item was launched based on his light sculptures. Named String Ray, 30,000 were sold in the US.

https://en.wikipedia.org/wiki/Manfredo%20do%20Carmo | Manfredo Perdigão do Carmo (15 August 1928, Maceió – 30 April 2018, Rio de Janeiro) was a Brazilian mathematician. He spent most of his career at IMPA and is seen as the doyen of differential geometry in Brazil.
Education and career
Do Carmo studied civil engineering at the University of Recife from 1947 to 1951. After working a few years as engineer, he accepted a teaching position at the newly created Institute of Physics and Mathematics at Recife.
On suggestion of Elon Lima, in 1959 he went to Instituto Nacional de Matemática Pura e Aplicada to improve his background and in 1960 he moved to the US to pursue a Ph.D. in mathematics at the University of California, Berkeley under the supervision of Shiing-Shen Chern. He defended his thesis, entitled "The Cohomology Ring of Certain Kahlerian Manifolds", in 1963.
After working again at University of Recife and at the University of Brasilia, in 1966 he became professor at Instituto Nacional de Matemática Pura e Aplicada (IMPA) in Rio de Janeiro. From 2003 to his death he was emeritus professor at the same institution.
Do Carmo was a Guggenheim Fellow in 1965 and 1968. In 1978 he was invited speaker at the International Congress of Mathematicians held in Helsinki. In 1991 he obtained a Doctorate honoris causa from Federal University of Alagoas and in 2012 from University of Murcia and from Federal University of Amazonas.
He served as president of the Brazilian Mathematical Society in the term 1971–1973. He was elected a member of the Brazilian Academy of Sciences in 1970, a member of The World Academy of Sciences (TWAS) in 1997 and a fellow of the American Mathematical Society In 2013.
Among his awards, he received the Prêmio Almirante Álavaro Alberto from the National Council for Scientific and Technological Development in 1984, the TWAS Prize in Mathematics in 1992, the National Order of Scientific Merit in 1995 and the Comenda Graciliano Ramos from the municipality of Maceió in 2000.
Do Carmo died on 30 April 2018 at the age of 89.
Research
Do Carmo's main research interests were Riemannian geometry and the differential geometry of surfaces.
In particular, he worked on rigidity and convexity of isometric immersions, stability of hypersurfaces and of minimal surfaces, topology of manifolds, isoperimetric problems, minimal submanifolds of a sphere, and manifolds of constant mean curvature and vanishing scalar curvature.
Do Carmo published more than 100 papers in peer-reviewed journals; in 2012 a selection of his works was published by Springer. He is also known for his textbooks: they were translated into many languages and used in courses from universities such as Harvard and Columbia.
He supervised 27 PhD students, including Celso Costa, Marcos Dajczer and Keti Tenenblat.

https://en.wikipedia.org/wiki/Rouben%20V.%20Ambartzumian | Rouben V. Ambartzumian (Armenian: ;) (born 1941) is an Armenian mathematician and Academician of National Academy of Sciences of Armenia. He works in Stochastic Geometry and Integral Geometry where he created a new branch, combinatorial integral geometry. The subject of combinatorial integral geometry received support from mathematicians K. Krickeberg and D. G. Kendall at the 1976 Sevan Symposium (Armenia) which was sponsored by Royal Society of London and The London Mathematical Society. In the framework of the later theory he solved a number of classical problems in particular the solution to the Buffon Sylvester problem as well as the Hilbert's fourth problem in 1976. He is a holder of the Rollo Davidson Prize of Cambridge University of 1982. Rouben's interest in Integral Geometry was inherited from his father. Nobel prize winner Allan McLeod Cormack Laureate for Tomography wrote: "Ambartsumian gave the first numerical inversion of the Radon transform and it gives the lie to the often made statement that computed tomography would have been impossible without computers". Victor Hambardzumyan, in his book "A Life in Astrophysics", wrote about the work of Rouben V. Ambartzumian, "More recently, it came to my knowledge that the invariance principle or invariant embedding was applied in a purely mathematical field of integral geometry where it gave birth to a novel, combinatorial branch." See R. V. Ambartzumian, «Combinatorial Integral Geometry», John Wiley, 1982.

https://en.wikipedia.org/wiki/Archetypal%20analysis | Archetypal analysis in statistics is an unsupervised learning method similar to cluster analysis and introduced by Adele Cutler and Leo Breiman in 1994. Rather than "typical" observations (cluster centers), it seeks extremal points in the multidimensional data, the "archetypes". The archetypes are convex combinations of observations chosen so that observations can be approximated by convex combinations of the archetypes.

https://en.wikipedia.org/wiki/Metal%E2%80%93insulator%E2%80%93metal | Metal–insulator–metal (MIM) diode is a type of nonlinear device very similar to a semiconductor diode and capable of very fast operation. Depending on the geometry and the material used for fabrication, the operation mechanisms are governed either by quantum tunnelling or thermal activation.
In 1948, Torrey et al. stated that "It should be possible to make metal–insulator–metal rectifiers with much smaller spreading resistances than metal–semiconductor rectifiers have, consequently giving greater rectification efficiency at high frequencies." But due to fabrication difficulties, two decades passed before the first device could be successfully created. Some of the very first MIM diodes to be fabricated came from Bell Labs in the late 1960s and early 1970s Brinkman et al. demonstrated the first zero-bias MIM tunneling diode with significant responsivity. When they are using tunneling transport, the MIM diode can be very fast. As soon as 1974, this diode was reportedly used as a mixer at 88 THz in a setup of the National Institute of Standards and Technology. Thanks to recent researches the zero-bias responsivity of the MIM diode (15 A/W) is now very close to the one of Schottky diode (19.4 A/W).
Today MIM diode is the cornerstone of the ongoing nantenna developments. They are also used as thin-film diode by the flat-panel display manufacturers.
In contrast to MIM diodes, metal–insulator–insulator–metal (MIIM) diodes have two insulator layers.

https://en.wikipedia.org/wiki/Tangential%20triangle | In geometry, the tangential triangle of a reference triangle (other than a right triangle) is the triangle whose sides are on the tangent lines to the reference triangle's circumcircle at the reference triangle's vertices. Thus the incircle of the tangential triangle coincides with the circumcircle of the reference triangle.
The circumcenter of the tangential triangle is on the reference triangle's Euler line, as is the center of similitude of the tangential triangle and the orthic triangle (whose vertices are at the feet of the altitudes of the reference triangle).
The tangential triangle is homothetic to the orthic triangle.
A reference triangle and its tangential triangle are in perspective, and the axis of perspectivity is the Lemoine axis of the reference triangle. That is, the lines connecting the vertices of the tangential triangle and the corresponding vertices of the reference triangle are concurrent. The center of perspectivity, where these three lines meet, is the symmedian point of the triangle.
The tangent lines containing the sides of the tangential triangle are called the exsymmedians of the reference triangle. Any two of these are concurrent with the third symmedian of the reference triangle.
The reference triangle's circumcircle, its nine-point circle, its polar circle, and the circumcircle of the tangential triangle are coaxal.
A right triangle has no tangential triangle, because the tangent lines to its circumcircle at its acute vertices are parallel and thus cannot form the sides of a triangle.
The reference triangle is the Gergonne triangle of the tangential triangle.

https://en.wikipedia.org/wiki/Polar%20circle%20%28geometry%29 | In geometry, the polar circle of a triangle is the circle whose center is the triangle's orthocenter and whose squared radius is
where denote both the triangle's vertices and the angle measures at those vertices; is the orthocenter (the intersection of the triangle's altitudes); are the feet of the altitudes from vertices respectively; is the triangle's circumradius (the radius of its circumscribed circle); and are the lengths of the triangle's sides opposite vertices respectively.
The first parts of the radius formula reflect the fact that the orthocenter divides the altitudes into segment pairs of equal products. The trigonometric formula for the radius shows that the polar circle has a real existence only if the triangle is obtuse, so one of its angles is obtuse and hence has a negative cosine.
Properties
Any two polar circles of two triangles in an orthocentric system are orthogonal.
The polar circles of the triangles of a complete quadrilateral form a coaxal system.
A triangle's circumcircle, its nine-point circle, its polar circle, and the circumcircle of its tangential triangle are coaxal.

https://en.wikipedia.org/wiki/Damath | Damath is a two-player educational board game combining the board game "Dama" (Filipino checkers) and math. It is used as a teaching tool for both elementary and high school mathematics. Every piece has a corresponding number and each even (white) square on board has a mathematical symbol. The game is commonly played in all elementary and secondary schools in the Philippines.
History
Damath was invented by Jesus Huenda, a teacher in the province of Sorsogon, Philippines, who had encountered problems in teaching math using traditional teaching methods. Inspired in part by an investigatory project called “Dama de Numero” submitted by a student (Emilio Hina Jr.) in 1975, Huenda overhauled the game and introduced it to his class, who enjoyed playing. Damath became popular and in 1980, the first Damath tournament was held in Sorsogon. The next year, Huenda received a gold medallion from the late President Ferdinand Marcos for his contributions in the field of teaching mathematics. The game reached its peak popularity in the 1990s, when it made the rounds of several mathematics education conventions all over the world such as the 10th Conference of the Mathematical Association of Western Australia (MAWA), the UNESCO-ICT4E conference in Thailand, the SEAMEO RECSAM/SEAMEC conference in Malaysia, and the APEC Learning Community Builders (ALCoB) conference in Korea. Damath was first introduced to the United States of America by an international Filipino educator, Reynaldo L. Duran at the National Council of Teachers of Mathematics (NCTM) Conference in New Mexico, USA in 2011.
Board and pieces
The board is similar to a checkerboard but with a twist. All even (white) tiles on the board have a mathematical symbol which dictates the operation that will be used when a player's piece captures the opponent's piece. It has numbers labeled 0-7 on its sides to determine the coordinates of the piece. Each piece of the player has corresponding values depending on what type of damath is being played. Both board and damath pieces are mostly made of thick cardboard or illustration board.
Gameplay
The rules are similar to checkers but there are some differences:
The goal is to have the most points at the end of the game.
Points are scored for each capture made during play and for each piece still on the board at the end of the game.
The games ends if a player has no pieces remaining (or cannot make a legal move), the moves are repetitive, or the twenty-minute time limit is reached.
Points are scored as follows
Each piece is assigned a value (printed on the piece)
When a capture is made, the score of the capture is calculated by using the mathematical operation shown on the space the capturing piece lands on, with the values of the capturing piece and the captured piece as the operands.
When a dama piece (king) captures or is captured, the score is doubled (or quadrupled when a dama piece captures a dama piece).
Each player also scores the value of their piece |
https://en.wikipedia.org/wiki/Anna%20Wienhard | Anna Katharina Wienhard (born 1977) is a German mathematician whose research concerns differential geometry, and especially the use of higher Teichmüller spaces to study the deformation theory of symmetric geometric structures. She is a director at the Max Planck Institute for Mathematics in the Sciences.
Education and career
Wienhard did her undergraduate studies at the University of Bonn, earning a double degree in theology and mathematics. Continuing at Bonn, she earned a doctorate in 2004 under the joint supervision of Hans Werner Ballmann and Marc Burger.
After holding temporary positions at the University of Basel, Institute for Advanced Study, and University of Chicago, she took a faculty position at Princeton University in 2007. She moved to Heidelberg as a full professor in 2012 and to Leipzig as a research director at the Max Planck Institute for Mathematics in the Sciences in 2022.
Recognition
From 2009 to 2013, Wienhard was a member of the Young Academy of the German Academy of Sciences Leopoldina and Berlin-Brandenburg Academy of Sciences and Humanities. In 2012, she became one of the inaugural fellows of the American Mathematical Society. She was elected as a regular member of the Leopoldina in 2023.
She was the Emmy Noether Lecturer of the German Mathematical Society in 2012, and an invited speaker at the 2018 International Congress of Mathematicians. She was named MSRI Clay Senior Scholar for Fall 2019.

https://en.wikipedia.org/wiki/RAMiCS | RAMiCS, the International Conference on Relational and Algebraic Methods in Computer Science, is an academic conference organized every eighteen months by an international steering committee and held in different locations mainly in Europe, but also in other continents. Like most theoretical computer science conferences, its contributions are strongly peer-reviewed. Proceedings of the conferences appear in Lecture Notes in Computer Science, and some of the stronger papers have been published in Journal of Logical and Algebraic Methods in Programming.
Early history
RAMiCS, then still called RelMiCS, was first organized by Chris Brink and Gunther Schmidt on January 17–21, 1994 in Schloß Dagstuhl, Germany as International Seminar on Relational Methods in Computer Science. The second RelMiCS was organized by the late Armando Haeberer and held July 10–14, 1995 in Paraty near Rio de Janeiro, Brazil. The 3rd International Seminar on the Use of Relational Methods in Computer Science (RelMiCS 3) was January 6–10, 1997 in Albatros Hotel in Hammamet, Tunisia. A 4th International Seminar on Relational Methods in Computer Science (RelMiCS 4) took place September 14–20, 1998 in Stefan Banach International Mathematical Centre, Sept. 2004, Warsaw, Poland. The 5th International Seminar on Relational Methods in Computer Science (RelMiCS 5) occurred January 9–14, 2000 at Valcartier near Québec, Canada. From that point on, publication was arranged with Springer in the series Lecture Notes in Computer Science.

https://en.wikipedia.org/wiki/Polynomial%20Wigner%E2%80%93Ville%20distribution | In signal processing, the polynomial Wigner–Ville distribution is a quasiprobability distribution that generalizes the Wigner distribution function. It was proposed by Boualem Boashash and Peter O'Shea in 1994.
Introduction
Many signals in nature and in engineering applications can be modeled as , where is a polynomial phase and .
For example, it is important to detect signals of an arbitrary high-order polynomial phase. However, the conventional Wigner–Ville distribution have the limitation being based on the second-order statistics. Hence, the polynomial Wigner–Ville distribution was proposed as a generalized form of the conventional Wigner–Ville distribution, which is able to deal with signals with nonlinear phase.
Definition
The polynomial Wigner–Ville distribution is defined as
where denotes the Fourier transform with respect to , and is the polynomial kernel given by
where is the input signal and is an even number.
The above expression for the kernel may be rewritten in symmetric form as
The discrete-time version of the polynomial Wigner–Ville distribution is given by the discrete Fourier transform of
where and is the sampling frequency.
The conventional Wigner–Ville distribution is a special case of the polynomial Wigner–Ville distribution with
Example
One of the simplest generalizations of the usual Wigner–Ville distribution kernel can be achieved by taking . The set of coefficients and must be found to completely specify the new kernel. For example, we set
The resulting discrete-time kernel is then given by
Design of a Practical Polynomial Kernel
Given a signal , where is a polynomial function, its instantaneous frequency (IF) is .
For a practical polynomial kernel , the set of coefficients and should be chosen properly such that

Applications
Nonlinear FM signals are common both in nature and in engineering applications. For example, the sonar system of some bats use hyperbolic FM and quadratic FM signals for echo location. In radar, certain pulse-compression schemes employ linear FM and quadratic signals. The Wigner–Ville distribution has optimal concentration in the time-frequency plane for linear frequency modulated signals. However, for nonlinear frequency modulated signals, optimal concentration is not obtained, and smeared spectral representations result. The polynomial Wigner–Ville distribution can be designed to cope with such problem.
