https://en.wikipedia.org/wiki/Wilf%20Malcolm | Wilfred Gordon Malcolm (29 November 1933 – 6 October 2018) was a New Zealand mathematician and university administrator. He was professor of pure mathematics at Victoria University of Wellington from the mid 1970s, until serving as vice-chancellor of the University of Waikato between 1985 and 1994.
Biography
Born in Feilding on 29 November 1933, Malcolm was educated at Feilding Agricultural High School. He went on to study at Wellington Teachers' College and Victoria University College, graduating Master of Arts with first-class honours in 1957. He won a Shirtcliffe Fellowship, which enabled him to take parts II and III of the Mathematical Tripos, specialising in algebra and topology, at the University of Cambridge. While in England, Malcolm married Edmée Ruth Prebensen.
Malcolm returned to Victoria, where he took up a lecturership in pure mathematics. Between 1964 and 1966, he spent time away from the university, working as the general secretary of the Inter-Varsity Fellowship of Evangelical Unions. However, he returned to lecturing at Victoria in 1967, and was promoted to senior lecturer the following year. In 1972, he completed his PhD thesis, titled Ultraproducts and higher order models, supervised by George Hughes and Max Cresswell from the Department of Philosophy, and C.J. Seelye from the Mathematics Department.
In 1985, Malcolm moved to the University of Waikato to take up the vice-chancellorship, serving in that role until 1994.
Malcolm was awarded the New Zealand 1990 Commemoration Medal in 1990. In the 1994 Queen's Birthday Honours, he was appointed a Commander of the Order of the British Empire, for services to tertiary education. The following year, he was conferred with an honorary doctorate by the University of Waikato. The Wilf Malcolm Institute of Educational Research at Waikato was named in his honour in 2002, in recognition of his contribution to education.
Malcolm died in Auckland on 6 October 2018.

https://en.wikipedia.org/wiki/Louise%20Doris%20Adams | Louise Doris Adams (2 July 1889 – 24 December 1965) was a British mathematics educator and school inspector (HMI) who wrote the 1953 book A Background to Primary School Mathematics (Oxford University Press) and became president of the Mathematical Association for 1959.
Life
Adams earned a degree from Bedford College, London, with second-class honours in mathematics in 1911.
Her work as an inspector was centred on the West Country and particularly Bristol; she retired from the inspectorate in 1950.
She joined the Mathematical Association in approximately 1915, and was a member for 51 years; she became a member of the Teaching Sub-Committee of the Mathematical Association in 1946, of which she became Chairman in 1954 and remained a member until her death. She was also a member of the Applications, Arithmetic and Secondary Modern Sub-Committees.
When she became president of the Mathematical Association in 1959, she became only the second woman to hold that office since the association's founding in 1871, after Mary Cartwright in 1951, and the second HMI, after W. C. Fletcher in 1939.
She died in 1965.
Contributions
Adams had "considerable experience as a teacher and inspector" and wrote her book, A Background to Primary School Mathematics (1953), on the basis of that experience. It was aimed at teachers of primary-school mathematics, and used case studies from approximately 80 students to advocate linking the teaching of mathematics to the individual experiences of the students. Her book "inspired many teachers" and prefigured a greater emphasis on play with mathematical tools over rote learning.
As a member of the Teaching Sub-Committee of the Mathematical Association, Adams helped shift the association's focus "from teaching to learning" and from what should be taught to how it should be taught, and promoted the inclusion of primary as well as secondary education within the project's scope. Both her book and her presidential address to the Mathematical Association were a major impetus to the reform of mathematical education in the UK, as was the Teaching Sub-Committee's 1955 report The Teaching of Mathematics in Primary Schools, which she was instrumental in writing.

https://en.wikipedia.org/wiki/Margaret%20Hayman | Margaret Hayman (1923 – 26 July 1994, born Margaret Riley Crann) was a British mathematics educator who co-founded the British Mathematical Olympiad, wrote mathematics textbooks, and became president of the Mathematical Association.
Life
Margaret Riley Crann was born on 7 August 1923 in New Earswick in North Yorkshire, where her father Thomas Crann was a research chemist and her mother a teacher; she grew up as a Quaker. After studying at the Mill Mount School in York,
she read mathematics and then geography in Newnham College, Cambridge, and earned a master's degree from the University of Cambridge, beginning in 1941 and finishing in 1944. She became a social worker in Birmingham for a year before taking a position as a mathematics teacher at Putney High School, a girls' school in London where she eventually became head of mathematics.
In 1947, she married mathematician Walter Hayman.
He writes that they met at the Jesus Lane Friends Meeting House in Cambridge, in her third and his first year at Cambridge, and that they fell in love after she hit him with a celery stick for making a pun. Beyond her professional interests, she was also an amateur violinist and activist, joining the Aldermaston Marches for CND, fundraising for various causes and, in her later years, joining the board of North Yorkshire MIND.
Margaret and Walter had three daughters: Daphne, Carolyn and Sheila.
She retired from Putney High School in 1985, and returned with her husband to Yorkshire. She died on 26 July 1994.
Contributions
In 1966, Hayman and her husband founded the British Mathematical Olympiad. Hayman took an active part in the meetings of proponents of the competition, helped negotiate the role of the British Olympiad in the International Mathematical Olympiad, and fought for funding for the competition and for the good will of the Mathematical Association towards the competition.
She taught master classes in mathematics teaching for the Royal Institution, and became the author of mathematical textbooks, including:
Multiple Choice Modern Mathematics (Nelson, 1969)
Essential Mathematics (Macmillan 1971)
She became president of the Mathematical Association for the 1974–1975 term, and a member of the council of the Institute of Mathematics and its Applications. Her philosophy as president of the Mathematical Association involved keeping the mathematics curriculum flexible enough to ensure that all pupils received a mathematical education fitting their individual needs.

https://en.wikipedia.org/wiki/Mary%20Bradburn | Mary Bradburn (1918–2000) was a British mathematics educator who became president of the Mathematical Association for the 1994–1995 term.
Education and career
Bradburn was born on 17 March 1918 in Normanby in North Yorkshire, the daughter of a marine engineer and a Scotswoman. She attended a school that didn't approve of girls studying mathematics, but allowed her to progress through the mathematics curriculum at her own rate, several years ahead of the other students.
She earned a state scholarship, but at 17, she was below the required age for Oxford and Cambridge, so she ended up going to Royal Holloway College. She was a student there beginning in 1935 and, despite multiple extracurricular activities, earned first class honours in mathematics in 1938, and completed a master's degree there in 1940.
With another scholarship from the University of London, she went to the University of Edinburgh for graduate study with Max Born, beginning in 1941; her dissertation was The Statistical Thermodynamics of Crystal Lattices.
She taught briefly at Edinburgh and the University of Dundee before
returning to Royal Holloway as an instructor in 1945. She remained at Royal Holloway through its 1965 transition from a women's college to a coeducational one (a change that she supported), until her retirement in 1980.
Recognition and legacy
She became a Fellow of the Royal Astronomical Society in 1955.
The mathematics department of Royal Holloway offers an annual prize to undergraduates, the Mary Bradburn Prize, named in her memory.
The British Federation of Women Graduates also offers a Mary Bradburn Prize,
from a bequest left by Bradburn.

https://en.wikipedia.org/wiki/Bobby%20Seagull | Jay Bobby Seagull (born 13 February 1984) is an English mathematics teacher, broadcaster and writer. He appeared on the television programme University Challenge in 2017, and in 2018 on Monkman & Seagull's Genius Guide to Britain. His second book, The Life-Changing Magic of Numbers, was published in 2018.
Early life and education
Seagull, the second of his parents' four sons all of whom were called Jay, grew up in the London Borough of Newham. His parents emigrated to East Ham from Kerala in India. He said on episode ten of The Answer Trap that "my first name is Jay because in my family there's a South Indian tradition, so Jay Dave, Jay Bobby, Jay John, Jay Thomas, and then my family name is Jose, from Kerala in South India". Asked by an interviewer in 2017 about his "pretty unusual" name, Bobby Seagull explained, "My dad was very taken by the book Jonathan Livingston Seagull". He attended St Michael's Primary School followed by St Bonaventure's in Upton Park. He is a fan of local football club West Ham United.
When he was growing up, his father would take his boys regularly to East Ham Library, where Seagull was encouraged to find books that interested him. His headteacher was Michael Wilshaw. After seeing an advertisement for sixth form scholarships at Eton College, he subsequently applied and studied at Eton. Seagull started studying mathematics at Lady Margaret Hall, University of Oxford, but left his degree and graduated from Royal Holloway, University of London.
Career
After graduating from Royal Holloway, University of London, Seagull joined Lehman Brothers as a trader. He was there during the financial crisis, and has spoken about the days before it filed for bankruptcy. He left banking and worked as an accountant for Pricewaterhouse Coopers. During this time, Seagull was involved with voluntary work and training new graduates.
Seagull did a PGCE at Hughes Hall, Cambridge and completed a master's degree in education at Emmanuel College whilst finishing his newly qualified teacher (NQT) year. He has taught at Chesterton Community College, Cambridge and East London Science School. Seagull is a part-time Maths teacher at a secondary school in London. He has created mathematics raps for his school classes. He is also leading a course on money management at the Open University. Since the start of 2018, Seagull has been pursuing a doctorate at the University of Cambridge concerning "mathematical anxiety and phobia".
He has been a columnist for the Financial Times since January 2018. Seagull has since become a national campaigner to improve maths literacy. He is concerned that in the United Kingdom it is acceptable to celebrate being bad at maths as if it is a badge of honour. He is also an advocate for maths teachers, supporting them in the creation of new materials and campaigning for better pay. He has said he wants to be the "Jamie Oliver of maths..Jamie Oliver helped to introduce healthy food in schools. I would love to be the equival |

https://en.wikipedia.org/wiki/Pat%20Courtney%20Gold | Pat Courtney Gold (January 22, 1939 – July 11, 2022) was a Wasco Native fiber artist and basket weaver from the Columbia River area of Oregon. She graduated with a BA in mathematics and physics from Whitman College and worked as a mathematician-computer specialist before beginning her career in basket weaving. Gold harvested traditional plant fibers to use in her work—including Dogbane, cattail, sedge grass, red cedar bark and tree roots. Her pieces often reflected the natural world along the Columbia River, mixing traditional motifs such as condors and sturgeon with contemporary figures like airplanes. Gold also became an environmental and cultural educator, helping to spread knowledge of her ancestral heritage and basketry skills.
Gold's art is exhibited in museums around the world, including the High Desert Museum, Royal British Columbia Museum, Peabody Museum of Archaeology and Ethnology at Harvard University and Smithsonian National Museum of the American Indian.
She was featured in a 2007 episode of the PBS series Craft in America.
Personal life
Gold was born and raised on the Warm Springs Reservation in central Oregon. Her mother was an accomplished beadworker, and they would visit local art museums where their ancestors' baskets were on display. She graduated from Madras High School in 1957.
As a child, Gold did not see anyone around her using traditional weaving techniques and had no idea that would one day become her career. She worked as a mathematician for nearly 17 years before she decided to change course and focus on reviving the culture and art of her people.
In 1991, through the Oregon Traditional Arts Apprenticeship Program, Gold began to study the making of "sally bags," flexible cylindrical baskets created by Wasco-Wishram people for gathering roots and medicines, as well as nuts, seeds and mushrooms. Gold diagrammed historical basket designs and learned about the stories they told, encompassing the symbolism of fishing nets, petroglyphs and other ancestral scenes. She learned the full turn twining technique used to weave the bags and has since become one of the foremost experts and teachers keeping this style alive today.
Published works
Awards and honors
Gold received an Oregon Governor's Arts Award in 2001. She earned a Community Spirit Award in 2003 and Cultural Capital Fellowship in 2004 from the First People's Fund. She was a recipient of a 2007 National Heritage Fellowship awarded by the National Endowment for the Arts, which is the United States government's highest honor in the folk and traditional arts.

https://en.wikipedia.org/wiki/Partial%20inverse%20of%20a%20matrix | In linear algebra and statistics, the partial inverse of a matrix is an operation related to Gaussian elimination which has applications in numerical analysis and statistics. It is also known by various authors as the principal pivot transform, or as the sweep, gyration, or exchange operator.
Given an matrix over a vector space partitioned into blocks:
If is invertible, then the partial inverse of around the pivot block is created by inverting , putting the Schur complement in place of , and adjusting the off-diagonal elements accordingly:
Conceptually, partial inversion corresponds to a rotation of the graph of the matrix , such that, for conformally-partitioned column matrices and :
As defined this way, this operator is its own inverse: , and if the pivot block is chosen to be the entire matrix, then the transform simply gives the matrix inverse . Note that some authors define a related operation (under one of the other names) which is not an inverse per se; particularly, one common definition instead has .
The transform is often presented as a pivot around a single non-zero element , in which case one has
Partial inverses obey a number of nice properties:
inversions around different blocks commute, so larger pivots may be built up from sequences of smaller ones
partial inversion preserves the space of symmetric matrices
Use of the partial inverse in numerical analysis is due to the fact that there is some flexibility in the choices of pivots, allowing for non-invertible elements to be avoided, and because the operation of rotation (of the graph of the pivoted matrix) has better numerical stability than the shearing operation which is implicitly performed by Gaussian elimination. Use in statistics is due to the fact that the resulting matrix nicely decomposes into blocks which have useful meanings in the context of linear regression.

https://en.wikipedia.org/wiki/Rectified%20prism | In geometry, a rectified prism (also rectified bipyramid) is one of an infinite set of polyhedra, constructed as a rectification of an n-gonal prism, truncating the vertices down to the midpoint of the original edges. In Conway polyhedron notation, it is represented as aPn, an ambo-prism. The lateral squares or rectangular faces of the prism become squares or rhombic faces, and new isosceles triangle faces are truncations of the original vertices.
Elements
An n-gonal form has 3n vertices, 6n edges, and 2+3n faces: 2 regular n-gons, n rhombi, and 2n triangles.
Forms
The rectified square prism is the same as a semiregular cuboctahedron.
Rectified star prisms also exist, like a 5/2 form:
Dual
The dual of a rectified prism is a joined prism or joined bipyramid, in Conway polyhedron notation. The join operation adds vertices at the center of faces, and replaces edges with rhombic faces between original and the neighboring face centers. The joined square prism is the same topology as the rhombic dodecahedron. The joined triangular prism is the Herschel graph.

https://en.wikipedia.org/wiki/Real%20radical | In algebra, the real radical of an ideal I in a polynomial ring with real coefficients is the largest ideal containing I with the same vanishing locus.
It plays a similar role in real algebraic geometry that the radical of an ideal plays in algebraic geometry over an algebraically closed field.
More specifically, the Nullstellensatz says that when I is an ideal in a polynomial ring with coefficients coming from an algebraically closed field, the radical of I is the set of polynomials vanishing on the vanishing locus of I. In real algebraic geometry, the Nullstellensatz fails as the real numbers are not algebraically closed. However, one can recover a similar theorem, the real Nullstellensatz, by using the real radical in place of the (ordinary) radical.
Definition
The real radical of an ideal I in a polynomial ring over the real numbers, denoted by , is defined as
The Positivstellensatz then implies that is the set of all polynomials that vanish on the real variety defined by the vanishing of .

https://en.wikipedia.org/wiki/Ferdinand%20Karl%20Schweikart | Ferdinand Karl Schweikart (1780–1857) was a German jurist and amateur mathematician who developed an astral geometry before the discovery of non-Euclidean geometry.
Life and work
Schweikart, son of an attorney in Hesse, was educated in the school of his town. He went to the high school in Hanau and Waldeck before entering in 1796 to study law in the university of Marburg, where he attended lectures of the mathematics professor J.K.F. Hauff. He was awarded a doctorate in law at the university of Jena in 1798.
After practicing as a lawyer for a few years in Erbach, he was, from 1803 to 1807, instructor of the youngest prince of Hohenlohe-Ingelfingen. From 1809, he was university professor of jurisprudence successively at the universities of Giessen (1809-1812), Kharkiv (1812-1816), Marburg (1816-1821) and Königsberg (1821 afterwards).
But Schweikart is best remembered for his works on mathematics: in 1807 he published Die Theorie der Parallellinien, nebst dem Vorschlage ihrer Verbannung aus der Geometrie (The theory of parallel lines, along with the suggestions of their banishment from geometry). Then, in 1818 he wrote to Gauss, through his student Christian Ludwig Gerling, about a new geometry, called by him as astral geometry, where the sum of the angles of a triangle was less than 180º (as in hyperbolic geometry). He influenced the work of his nephew, the mathematician Franz Taurinus.

https://en.wikipedia.org/wiki/Giuseppina%20Masotti%20Biggiogero | Giuseppina Masotti Biggiogero (8 August 1894 – 24 October 1977) was an Italian mathematician and historian. Known for her work in algebraic geometry, she also wrote noted histories of mathematicians, like Maria Gaetana Agnesi and Luca Pacioli. She was a member of the and won both the Bordoni Prize and Torelli Prize for her work.
Early life
Giuseppina Biggiogero was born on 8 August 1894 in Melegnano, Italy to Marta (née Massironi) and Biagio Biggiogero. She completed her primary and secondary studies in Lodi, earning a degree as a teacher in 1912. While continuing her studies at the Carlo Cattaneo Technical Institute, she began teaching elementary school, first in Carpiano and later in Melegnano.
At the time that she was studying, the only paths available to enter university were to obtain a high school diploma, which was not typically available to women, or to obtain a degree from a technical institute. In 1916, Biggiogero earned her certificate with a specialty in physics and mathematics.
Receiving a scholarship to attend the Politecnico di Milano in 1917, she quit her teaching post. She initially began her studies in engineering, but in 1918 moved to the mathematics courses. Because the Politecnico did not offer a specific curriculum for math, she transferred in 1919 to the University of Pavia, where she studied under the instruction of . She graduated in 1921, obtaining her diploma for teaching in pure mathematics. Working as an assistant to the professors Luigi Berzolari and Francesco Gerbaldi, Biggiogero published two works on real algebraic curves, which were recognized with the Bordoni and Torelli prizes. Her 1922 book, was titled Sulle curve piane, algebriche, reali che presentano massimi d'inclusione and she published Gruppi di massimi d'inclusione per curve piane, algebriche, reali, d'ordine n in 1923.
Career
In 1924, eager to work with Oscar Chisini, Biggiogero returned to Milan and was appointed as his assistant and the professor for the descriptive and projective geometry courses at the Politecnico di Milano. From 1927, she also gave lectures at the Mathematical and Physical Seminary of Milan, which was founded in that year, and taught higher and projective geometry courses at the University of Milan. She was assigned as the editor of the mathematical entries in the Enciclopedia Italiana (Italian Encyclopedia, 1933) and reviewed the first sixteen volumes of the work, focusing on the compilations of Federigo Enriques. In 1939, Biggiogero married Arnaldo Masotti, a fellow academic, who at the time was the professor of Rational Mechanics in the Faculty of Architecture. She was made chair of Geometry at the Politecnico in 1948 and retained that post until her retirement in 1969. In addition to lecturing on descriptive geometry in the mathematics department, she taught projective geometry to the students in the architectural and engineering departments.
Biggiogero's research produced a large body of work on algebraic geometry, incl |
https://en.wikipedia.org/wiki/Jenny%20Bryan | Jennifer "Jenny" Bryan is a data scientist and an associate professor of statistics at the University of British Columbia where she developed the Master in Data Science Program. She is a statistician and software engineer at RStudio from Vancouver, Canada and is known for creating open source tools which connect R to Google Sheets and Google Drive.
Education
Bryan earned her Bachelor of Arts in Economics and German literature from Yale University in 1992 and her PhD in Biostatistics from University of California, Berkeley in 2001.
Career
As an associate professor of statistics at the University of British Columbia, Bryan worked on biostatistics with a focus on gene expression and microarray data. Notable projects to which she has contributed include the quantification of photomotor responses in larval zebrafish, the development of an assay system in the multicellular animal Caenorhabditis elegans to test genetic interactions causing synthetic lethality in somatic cells, and a novel yeast-based model to search for modifier genes involved in cystic fibrosis. Beyond biostatistics, Bryan has also contributed to medoids-based clustering methods. Her general science contributions include a manifesto published in PLOS One on good practices for scientific computing and an introduction to the Git version control system for research data analysis.
Bryan's teaching activities at UBC included development of the Master of Data Science Program and new materials for the STAT 545 course. Under Bryan's direction, the STAT 545 course became notable as an early example of a data science course taught in a statistics program. It is also notable for its focus on teaching using modern R packages, Git and GitHub, its extensive sharing of teaching materials openly online, and its strong emphasis on practical data cleaning, exploration, and visualization skills, rather than algorithms and theory. As of late 2016 Bryan is on leave from her UBC position and is working at RStudio with a team led by Hadley Wickham.
Bryan has had experience with S and R since 1996. She is known for her open source contributions in R. Influential contributions include the use of Lego and the concept of data rectangling for explaining programming concepts, reproducible research, and advice on project and workflow organisation.
Bryan is well known for her work on efficient methods of working in spreadsheets, and the connection between R and spreadsheet software such as Excel and Google Sheets. She is the primary developer of the R package googlesheets, that connects R to the Google Sheets service, and googledrive, an R package for interfacing between R and Google Drive.
Bryan is known for her work in teaching, her contributions to R packages, and her involvement with the leadership committee at rOpenSci. She is also part of the R Foundation Forwards task force and a member of the editorial board of BMC Bioinformatics. Previously, she worked as an Associate at the Boston Consulting Grou |

https://en.wikipedia.org/wiki/Bendixson%27s%20inequality | In mathematics, Bendixson's inequality is a quantitative result in the field of matrices derived by Ivar Bendixson in 1902. The inequality puts limits on the imaginary and real parts of characteristic roots (eigenvalues) of real matrices. A special case of this inequality leads to the result that characteristic roots of a real symmetric matrix are always real.
The inequality relating to the imaginary parts of characteristic roots of real matrices (Theorem I in ) is stated as:
Let be a real matrix and . If is any characteristic root of , then
If is symmetric then and consequently the inequality implies that must be real.
The inequality relating to the real parts of characteristic roots of real matrices (Theorem II in ) is stated as:

https://en.wikipedia.org/wiki/Wigner%20surmise | In mathematical physics, the Wigner surmise is a statement about the probability distribution of the spaces between points in the spectra of nuclei of heavy atoms, which have many degrees of freedom, or quantum systems with few degrees of freedom but chaotic classical dynamics. It was proposed by Eugene Wigner in probability theory. The surmise was a result of Wigner's introduction of random matrices in the field of nuclear physics. The surmise consists of two postulates:
In a simple sequence (spin and parity are same), the probability density function for a spacing is given by,
Here, where S is a particular spacing and D is the mean distance between neighboring intervals.
In a mixed sequence (spin and parity are different), the probability density function can be obtained by randomly superimposing simple sequences.
The above result is exact for real symmetric matrices , with elements that are independent standard gaussian random variables, with joint distribution proportional to
In practice, it is a good approximation for the actual distribution for real symmetric matrices of any dimension. The corresponding result for complex hermitian matrices (which is also exact in the case and a good approximation in general) with distribution proportional to , is given by
History
During the conference on Neutron Physics by Time-of-Flight, held at Gatlinburg, Tennessee, November 1 and 2, 1956, Wigner delivered a presentation on the theoretical arrangement of neighboring neutron resonances (with matching spin and parity) in heavy nuclei. In the presentation he gave the following guess:

Mathematicians of the African Diaspora
In 1997 Scott W. Williams of the University at Buffalo, SUNY created the website Mathematicians of the African Diaspora (MAD) dedicated to promoting and highlighting the contributions of members of the African diaspora to mathematics, especially contributions to current mathematical research. Williams retired in 2008 and it was left to others to continue the website he had spent 11 years building. After an initial town hall meeting about the future of the MAD Pages which took place at a Conference for African American Researchers in the Mathematical Sciences (CAARMS), an informal group of mathematicians decided to work together to preserve Williams’ work. In 2015, the National Association of Mathematicians (NAM) formed an ad hoc committee to update the MAD Pages, consisting of Edray Goins as NAM President, Committee Co-Chairs Don King (Northeastern University) and Asamoah Nkwanta (Morgan State University), and web developer John Weaver (Varsity Software).

Early life and education
Churchhouse was born on 30 December 1927 in Higher Blackley, Manchester. The son of Robert Francis, a laboratory assistant, and Agnes Churchhouse (née Howard), a cotton mill worker. Churchhouse grew up into a Roman Catholic family. He attended St Clare's RC Primary School, and then St Bede's College, Manchester from 1939 to 1946. He pursued an undergraduate education in mathematics at Manchester University, where he was taught by both Max Newman and Alan Turing, both now famous for their code breaking work at Bletchley Park in WW2. Churchhouse graduated with a first class honours degree and subsequently received an award to undertake a PhD in Number Theory at Trinity Hall, Cambridge under the supervision of Professor Louis J. Mordell. His time at Cambridge brought him into contact with other ex-Bletchley mathematicians.
Career
In 1952, for his national service, Churchhouse joined the Royal Navy Scientific Service, and then the Government Communications Headquarters (GCHQ) where he worked for 11 years in London, Cheltenham, and at the UK's embassy in Washington. The GCHQ was interested in his work in number theory, and he was initially interviewed in May 1952. During his time at the GCHQ, he worked with Hugh Alexander and Jack Good both of whom had also worked at Bletchley Park on the breaking of the Enigma code.
In 1962, he was appointed head of programming at the Atlas Computer Laboratory at Harwell where he worked on the Atlas I supercomputer until 1971.
Churchhouse left Atlas in 1971 and joined Cardiff University as an Inaugural Professor and head of the newly created Department of Computing Mathematics. He was also the Director of the Cardiff University Computer Centre for the early part of his tenure.
In 1965, Bob was asked to serve on the Flowers Committee responsible for the provision of computers to Universities and Research Councils and was subsequently asked to serve on the follow-up Computer Board. He chaired the Computer Board from 1979 to 1982 and was subsequently awarded a CBE for his services.
As a lifelong Catholic, he helped reorganise the Catholic Secondary Schools in Cardiff as well as serving on the Board of Governors of Saint David's Sixth Form College for 15 years. He was recognized for his service with an Papal Knighthood (KSG) in 1988.

https://en.wikipedia.org/wiki/Distance%20set | In geometry, the distance set of a collection of points is the set of distances between distinct pairs of points. Thus, it can be seen as the generalization of a difference set, the set of distances (and their negations) in collections of numbers.
Several problems and results in geometry concern distance sets, usually based on the principle that a large collection of points must have a large distance set (for varying definitions of "large"):
Falconer's conjecture is the statement that, for a collection of points in -dimensional space that has Hausdorff dimension larger than , the corresponding distance set has nonzero Lebesgue measure. Although partial results are known, the conjecture remains unproven.
The Erdős–Ulam problem asks whether it is possible to have a dense set in the Euclidean plane whose distance set consists only of rational numbers. Again, it remains unsolved.
Fermat's theorem on sums of two squares characterizes the numbers in the distance set of the two-dimensional integer lattice: they are the square roots of integers whose prime factorization does not contain an odd number of copies of any prime congruent to 3 mod 4. Analogously, Legendre's three-square theorem characterizes the distance set of the three-dimensional integer lattice, and Lagrange's four-square theorem characterizes the distance set of integer lattices in four and higher dimensions as being the square roots of integers without any additional constraints. In lattices of five or more dimensions, every subset of the lattice with nonzero upper density has a distance set containing the squares of an infinite arithmetic progression.
According to the Erdős–Anning theorem, every infinite set of points in the Euclidean plane that does not lie on one line has a non-integer in its distance set.
Square grids of points have distance sets of sublinear size, in contrast to points in general position whose distance set is quadratic in size. However, according to the 2015 solution of the Erdős distinct distances problem by Larry Guth and Nets Katz, the distance set of any finite collection of points in the Euclidean plane is only slightly sublinear, nearly as large as the given collection. In particular, only a finite collection of points can have a finite distance set.
A Golomb ruler is a finite set of points on a line such that no two pairs of points have the same distance. Sophie Piccard claimed that no two Golomb rulers have the same distance sets. The claim is incorrect, but there is only one counterexample, a pair of six-point Golomb rulers with a shared distance set.
The equilateral dimension of a metric space is the largest size of a collection of points whose distance set has only a single element. Kusner's conjecture states that the equilateral dimension of a -dimensional space with the Manhattan distance is exactly , but this remains unproven.
A 2-distance set is a set of points for which the set of distinct mutual distances has cardinality exactly 2. An example of |
https://en.wikipedia.org/wiki/Clara%20Latimer%20Bacon | Dr Clara Latimer Bacon (13 August 1866 – 14 April 1948) was a mathematician and Professor of Mathematics at Goucher College. She was the first woman to earn a PhD in mathematics from Johns Hopkins University.
Biography
Bacon was the daughter of Larkin Crouch Bacon and Louisa Latimer. She was born in Knox, Illinois, the eldest of her parents four children. She also had four other half siblings.
Bacon attended North Abingdon High School and begun her college life at Hedding Collegiate Seminary.
She graduated from Hedding College in Abingdon, USA, in 1886 with a bachelor's degree (the degree of PhB). She achieved a second bachelor's degree from Wellesley College in 1890. Later, Bacon taught in a private school in Litchfield, Kentucky and in three different schools over seven years. Bacon studied for her master's degree at the University of Chicago, completing her thesis in 1903 and graduating in September 1904, after six summers of study while continuing to work full time at the Woman's College of Baltimore.
In 1907, Johns Hopkins University had been admitted the women officially. Bacon applied to Hopkins at the same time. She achieved her PhD from Johns Hopkins University in 1911, one of only four women to receive a PhD from the university that year, the first year that women were granted PhDs without special approval from the trustees. At Johns Hopkins, Bacon was a student of the geometer Frank Morley, who was her dissertation adviser. Her thesis was published in American Journal of Mathematics in 1913. Her research in her Masters and PhD theses was on planar geometry.
She was Emeritus Professor of Mathematics at Goucher College, formerly known as Women's College Baltimore, in Maryland, USA, after working on the faculty from 1897 to 1934. She began teaching there in 1897, at the invitation of Dr John Franklin Goucher, and in 1905 became an associate professor, and in 1914 a full professor.
Bacon was a member of the American Mathematical Society and the Mathematical Association of America. She was president of the Baltimore chapter of the American Association of University Professors and supported the League of Women Voters.
A student hall of residence at Goucher College, Bacon House, is named in her honour.
She died on 14 April 1948, aged 81.

}The "Concrete Ship" is a former concrete ship built in Germany in 1943 originally named Sip. It transported goods and was used as a hospital ship transporting wounded troops to land-based treatment facilities. Post-war it was moved to Belgrade and used for housing employees of the Belgrade Excavator Company and their families. Beginning in the 1990s, the ship fell into disrepair. It was finally purchased by Skitrack International, restored and opened to the public as a tourist attraction and a public space in Belgrade, Serbia, in 2016.
Names
The ship was originally named after the Sip Canal, one of the key strategic positions of the German army on the Danube at Djerdap/Iron Gates gorge during the Second World War.
Large and heavy ships have long struggled to move upstream against the fast, strong current of the Danube river. To overcome this, a railroad track was built beside the canal. Trains ran along the track using thick cables to drag ships upstream against the current. As this ship was one of the heaviest in the fleet, it was named Sip.
After the Sip Canal was flooded in 1969 with the construction of the Iron Gate I Hydroelectric Power Station, the ship was renamed Concrete Ship in accordance with ferryman superstition.
History
World War II
During the Second World War, the global scarcity of raw steel inspired German engineers to design and create concrete ships. They used up to 70% less steel in their construction than traditional steel vessels. The idea of building concrete ships dates back to 1848 in France. Around 100 such ships were constructed in the United States during World War I for similar reasons.
Concrete ships are immune to magnetically triggered naval mines. Adolf Hitler ordered the production of 50 concrete ships to deliver necessary raw materials (such as oil, weaponry, food etc.) through the mine-filled rivers of Nazi Germany.
The Sip was built in 1943 in the second round of production. It was constructed in Ostvind (Swinemunde), by Schalenbau KG, Dyckerhoff & Widmann KG. It was part of a fleet that ensured the continuous flow of oil from Romania to Germany, as well as other necessary raw materials along the entire Danube river.
Additionally, the ship played an important role in the care and transportation of seriously wounded troops to land-based hospitals in Austria and Germany for further treatment. The Sip had multiple specialized areas for hospital functions: ambulance and operating room, wards for the wounded, hospital mess, storerooms for food, water, and medicines, as well as a staff room.
The Sip did not have engines. They were removed to make room for the steam boiler and the central heating system, by which the entire ship was heated during the |

https://en.wikipedia.org/wiki/Yomtov%20Garti | Yomtov Bonjour Garti (2 September 1915 – 21 February 2011) was a Turkish mathematician and a teacher of mathematics, physics and cosmography in Istanbul, Turkey.
Life
Yomtov Garti was born in Kadıköy, at the Asian part of Istanbul (Ottoman Empire, later to become Turkey). His father Maer Garti was a veterinarian doctor, who died in the typhus epidemics during the World War I, while serving in the Ottoman Army. Yomtov Garti was educated at the French high school Lycée Saint-Joseph, Istanbul . After graduating from the Department of Mathematics and Physics of Istanbul University, he was approached by the famous mathematician Richard Edler von Mises, who was then located in Istanbul and proposed him a PhD position. Garti's PhD was on statistics and probability theory tutored by Richard Edler von Mises and William Prager.
Yomtov Garti received his PhD in 1939, as the first PhD student of von Mises and third PhD of Turkey. He later published his findings in an article (Garti, 1940), which is a generalization of initial distributions to n dimensions published in(cited in). Garti served as an assistant for a summer to Harry Dember, a professor in the Institute of Applied Physics in Istanbul. After receiving his doctoral degree in 1939, he started to teach at famous high schools in Istanbul. In 1954, he presented an article to Richard von Mises in a book published in his honor.
Yomtov Garti continued teaching until age 92. He died, at the age of 96 in 2011. All main newspapers of Turkey announced the loss of “The teacher of teachers”. At his funeral, the several generations of students overfilled the Hemdat Israel Synagogue at Kadıköy, Istanbul.
Career
Yomtov Garti became a renowned mathematics teacher in Istanbul. He thought mathematics and physics to thousands of students over six decades, in several famous schools, namely Galatasary High School (Galatasaray Lisesi), Haydarpaşa High School, Lycee Saint-Joseph Istanbul, and Notre Dame de Sion Lisesi. He also thought in Musevi Lisesi and Boğaziçi Üniversity.
Yomtov Garti was rewarded the title of “Chevalier” of “Ordre des Palmes Academiques” by the French Government in recognition of his educational work in French schools in Turkey.

https://en.wikipedia.org/wiki/List%20of%20Major%20League%20Baseball%20career%20fielding%20errors%20as%20a%20center%20fielder%20leaders | In baseball statistics, an error is an act, in the judgment of the official scorer, of a fielder misplaying a ball in a manner that allows a batter or baserunner to advance one or more bases or allows an at bat to continue after the batter should have been put out. The center fielder (CF) is one of the three outfielders, the defensive positions in baseball farthest from the batter. Center field is the area of the outfield directly in front of a person standing at home plate and facing beyond the pitcher's mound. The outfielders' duty is to try to catch long fly balls before they hit the ground or to quickly catch or retrieve and return to the infield any other balls entering the outfield. Generally having the most territory to cover, the center fielder is usually the fastest of the three outfielders, although this can also depend on the relative strength of their throwing arms and the configuration of their home field, due to the deepest part of center field being the farthest point from the infield and home plate. The center fielder normally plays behind the shortstop and second baseman, who play in or near the infield; unlike catchers and most infielders (excepting first basemen), who are virtually exclusively right-handed, center fielders can be either right- or left-handed. In the scoring system used to record defensive plays, the center fielder is assigned the number 8.
The list of career leaders is dominated by players from the early 20th century; only three of the top 25 players were active after 1953. Only nine of the top 71 single-season totals were recorded after 1927, only one after 1939; only five of the top 183 totals were recorded after 1964. To a large extent, the leaders reflect longevity rather than lower skill. Tris Speaker, who holds the modern (post-1900) record of 227 errors committed as a center fielder, is often regarded as the greatest outfielder in history, setting records for putouts and assists; Willie Mays, whose 139 errors are the most by a center fielder since 1930, won twelve Gold Glove Awards for defensive excellence.
Because game accounts and box scores often did not distinguish between the outfield positions, there has been some difficulty in determining precise defensive statistics prior to 1901; because of this, and because of the similarity in their roles, defensive statistics for the three positions are frequently combined. Although efforts to distinguish between the three positions regarding games played during this period and reconstruct the separate totals have been largely successful, separate error totals are unavailable; players whose totals are missing the figures for pre-1901 games are notated in the table below. Tris Speaker is the post-1900 leader in career errors committed as a center fielder with 227; Ty Cobb (208) is second, and is the only other center fielder to commit over 200 career errors. Lorenzo Cain, who had 39 errors through the 2022 season to place him tied for 130th all-time, is the |
https://en.wikipedia.org/wiki/Test%20of%20Mathematics%20for%20University%20Admission | The Test of Mathematics for University Admission is a paper-based test sometimes used in the United Kingdom and other countries in Africa and the United States all assess the mathematical thinking and reasoning skills needed for undergraduate mathematics courses or courses featuring mathematics. A number of universities across the world accept the test as an optional part of their application process for mathematics-based courses.
History
The test was developed by Cambridge Assessment Admissions Testing and launched in 2016. It was designed to assess the key skills that students need to succeed on demanding university-level mathematics courses, and assist university mathematics tutors in making admissions decisions.
Durham University and Lancaster University began using the test in 2016, with the University of Warwick, the University of Sheffield and the University of Southampton recognising the test in 2017, and the London School of Economics and Political Science (LSE) and Cardiff University in 2018
Research indicates that the test has good predictive validity, with good correlation between candidates' scores in the test and their performance in their exams at the end of first year university study. There is also correlation between A-level Further Maths performance and performance in the test.
Test format and specification
The Test of Mathematics for University Admission is a paper-based 2 hour and 30 minute long test. It has two papers which are taken consecutively.
Paper 1: Mathematical Thinking
Paper 1 has 20 multiple-choice questions, with 75 minutes allowed to complete the paper. This paper assesses a candidate’s ability to apply their knowledge of mathematics in new situations. It comprises a core set of ideas from Pure Mathematics. These ideas reflect those that would be met early on in a typical A Level Mathematics course: algebra, basic functions, sequences and series, coordinate geometry, trigonometry, exponentials and logarithms, differentiation, integration, graphs of functions. In addition, knowledge of the GCSE curriculum is assumed.
Paper 2: Mathematical Reasoning
Paper 2 has 20 multiple-choice questions, with 75 minutes allowed to complete the paper. The second paper assesses a candidate’s ability to justify and interpret mathematical arguments and conjectures, and deal with elementary concepts from logic. It assumes knowledge of the Paper 1 specification and, in addition, requires students to have some knowledge of the structure of proof and basic logical concepts.
Calculators or dictionaries are not allowed to be used in the test.
Scoring
There is no pass/fail for the test. Candidates’ scores are determined by the number of correct answers given in both papers. Each question has the same weighting, and no penalties are given for incorrect answers. Raw scores are converted to a scale of 1.0 to 9.0 (with 9.0 being the highest). A score is also reported for each of the two papers (also reported on the 1.0 to 9.0 s |

https://en.wikipedia.org/wiki/List%20of%20Egyptian%20Premier%20League%20clubs | The following is a list of clubs who have played in the Egyptian Premier League since its formation in 1948 to the current season. All statistics here refer to time in the Egyptian Premier League only, with the exception of 'Most Recent Finish' (which refers to all levels of play) and 'Last Promotion' (which refers to the club's last promotion from the second tier of Egyptian football). Egyptian Premier League teams playing in the 2018–19 season are indicated in bold, while founding members of the Egyptian Premier League are shown in italics. If the longest spell is the current spell, this is shown in bold, and if the highest finish is that of the most recent season, then this is also shown in bold.
As of the 2018–19 season, sixty-nine teams have played in the Egyptian Premier League. Five of the eleven founder members of the Egyptian Premier League are competing in the 2018–19 season. Two (Al Ahly and Zamalek) have contested every season of the Egyptian Premier League. Three (Ismaily, Al Ittihad, and Al Masry) were also founder members, though each team has been relegated at least once in the past.
As of the 2018–19 season, eight clubs, El Dakhleya, ENPPI, Misr Lel Makkasa, Nogoom, Petrojet, Smouha, Tala'ea El Gaish and Wadi Degla, are not founding members of the Egyptian Premier League, but have never been relegated since their debut in the Egyptian Premier League.
Table
El Mansoura have had the most separate spells in the Egyptian Premier League, with eight; two of their spells lasted a single season. The club were relegated for the first time during the 1957–58 season after losing the relegation play-offs, but managed to reach the top tier again after four seasons. This was one of the few seasons that the league had a relegation play-off competition instead of direct relegation. Their second spell in the Egyptian Premier League lasted only two years, finishing last in both seasons. They finished last in Group B of the 1962–63 season but won the relegation play-offs after they won against El Minya, who were last in Group A. In the 1963–64 season, they were automatically relegated and no relegation play-off competition was held. The club promoted again in 1974 and managed to stay at the top tier until the 1981–82 season; they finished second from bottom and relegated with four points away from the safe spot. Three years later, managed to promote to the Egyptian Premier League again but they were relegated during the 1986–87 season after finishing last again, but with only two points away from the safe spot. They gained promotion again in 1990 and stayed at the top tier for two years, until they got relegated after finishing last again in the 1991–92 season. They were promoted in the next season, but then suffered from an immediate relegation in the 1993–94 season, but managed to return to the Egyptian Premier League again after only season; which was the start of their best spell.

https://en.wikipedia.org/wiki/Dichotomous%20thinking | In statistics, dichotomous thinking or binary thinking is the process of seeing a discontinuity in the possible values that a p-value can take during null hypothesis significance testing: it is either above the significance threshold (usually 0.05) or below. When applying dichotomous thinking, a first p-value of 0.0499 will be interpreted the same as a p-value of 0.0001 (the null hypothesis is rejected) while a second p-value of 0.0501 will be interpreted the same as a p-value of 0.7 (the null hypothesis is accepted). The fact that first and second p-values are mathematically very close is thus completely disregarded and values of p are not considered as continuous but are interpreted dichotomously with respect to the significance threshold. A common measure of dichotomous thinking is the cliff effect. A reason to avoid dichotomous thinking is that p-values and other statistics naturally change from study to study due to random variation alone; decisions about refutation or support of a scientific hypothesis based on a result from a single study are therefore not reliable.
Dichotomous thinking is very often associated with p-value reading but it can also happen with other statistical tools such as interval estimates.

https://en.wikipedia.org/wiki/Quota%20rule | In mathematics and political science, the quota rule describes a desired property of a proportional apportionment or election method. It states that the number of seats that should be allocated to a given party should be between the upper or lower roundings (called upper and lower quotas) of its fractional proportional share (called natural quota). As an example, if a party deserves 10.56 seats out of 15, the quota rule states that when the seats are allotted, the party may get 10 or 11 seats, but not lower or higher. Many common election methods, such as all highest averages methods, violate the quota rule.
Mathematics
If is the population of the party, is the total population, and is the number of available seats, then the natural quota for that party (the number of seats the party would ideally get) is
The lower quota is then the natural quota rounded down to the nearest integer while the upper quota is the natural quota rounded up. The quota rule states that the only two allocations that a party can receive should be either the lower or upper quota. If at any time an allocation gives a party a greater or lesser number of seats than the upper or lower quota, that allocation (and by extension, the method used to allocate it) is said to be in violation of the quota rule. Another way to state this is to say that a given method only satisfies the quota rule if each party's allocation differs from its natural quota by less than one, where each party's allocation is an integer value.
Example
If there are 5 available seats in the council of a club with 300 members, and party A has 106 members, then the natural quota for party A is . The lower quota for party A is 1, because 1.8 rounded down equal 1. The upper quota, 1.8 rounded up, is 2. Therefore, the quota rule states that the only two allocations allowed for party A are 1 or 2 seats on the council. If there is a second party, B, that has 137 members, then the quota rule states that party B gets , rounded up and down equals either 2 or 3 seats. Finally, a party C with the remaining 57 members of the club has a natural quota of , which means its allocated seats should be either 0 or 1. In all cases, the method for actually allocating the seats determines whether an allocation violates the quota rule, which in this case would mean giving party A any seats other than 1 or 2, giving party B any other than 2 or 3, or giving party C any other than 0 or 1 seat.
Relation to apportionment paradoxes
The Balinski–Young theorem proved in 1980 that if an apportionment method satisfies the quota rule, it must fail to satisfy some apportionment paradox. For instance, although Largest remainder method satisfies the quota rule, it violates the Alabama paradox and the population paradox. The theorem itself is broken up into several different proofs that cover a wide number of circumstances.
Specifically, there are two main statements that apply to the quota rule:
Any method that follows the quota rule must f |
https://en.wikipedia.org/wiki/Hinduism%20in%20Guadeloupe | Hinduism is a minority religion in Guadeloupe, followed by some Indo-Guadeloupeans. According to a statistics data, Hinduism is practised by 0.5% of the people in Guadeloupe.
Temples
There are a sizeable number of Hindu Tamil temples that are located in Basse-Terre, and other regions. There is a Hindu temple in dravidian style in Changy in Basse Terre and another one in Gaschet in Grande-Terre
Demographics
Although the Indo-Guadeloupeans constitute about 14% of the Guadeloupe, only some of them are still Hindus. Most of the Indo-Guadelopeans are Catholics, but they also worship Hindu gods. Ernest Moutoussamy, first Indo-Guadelopean member of the French Parliament said in an interview that "Though we are Catholics, we still have images of Hindu gods at home. We celebrate all the Christian festivals but we don’t celebrate Deepavali."
Revival
Revival of Hinduism happened in the last few decades. Many associations for the promotion of Hinduism and Indian culture have appeared during the 90's. The Institut du Monde Indien (Institute for the study of the Indian world) was begun by Jacques Sidambarom, Jean-Claude Petapermal and Roland Gopy to resuscitate Hindu rituals and connect Hindus in Trinidad and Tobago, Reunion, Pondicherry and Paris. Temples were also constructed as a part of it. Hindu religious rituals were also reactivated. Hindu festivals like Diwali and Pongal were also started celebrating.

https://en.wikipedia.org/wiki/Helen%20Popova%20Alderson | Helen Popova Alderson (1924–1972) was a Soviet and British mathematician and mathematics translator known for her research on quasigroups and on higher reciprocity laws.
Life
Alderson was born on 14 May 1924 in Baku, then part of the Soviet Union, to a family of two academics from Moscow. Her father, a neurophysiologist, had been a student of Ivan Pavlov. She began studying mathematics at Moscow University in 1937, when she was only 13. She had to break off her studies because of World War II, moving to Paris as a refugee with her family.
After the war, she returned to study at the University of Edinburgh. She completed a Ph.D. there in 1951; her dissertation was Logarithmetics of Non-Associative Algebras.
After leaving mathematical research to raise two children in Cambridge, she was funded by the Calouste Gulbenkian Foundation with a Fellowship at Lucy Cavendish College, Cambridge, beginning in the late 1960s. At Cambridge, she worked with J. W. S. Cassels.
She died on 5 November 1972, from complications of kidney disease.
Research
In the theory of higher reciprocity laws, Alderson published necessary and sufficient conditions for 2 and 3 to be seventh powers, in modular arithmetic modulo a given prime number .
According to , "plain quasigroups were first studied by Helen Popova-Alderson, in a series of papers dating back to the early fifties".
Smith cites in particular a posthumous paper and its references. In this context, a quasigroup is a mathematical structure consisting of a set of elements and a binary operation that does not necessarily obey the associative law, but where (like a group) this operation can be inverted. Being plain involves having only a finite number of elements and no non-trivial subalgebras.
Translation
As well as Russian, English, and French, Alderson spoke Polish, Czech, and some German. She became the English translator of Elementary Number Theory, a textbook originally published in Russian in 1937 by B. A. Venkov. Her translation was published by Wolters-Noordhoff of Groningen in 1970. As well as the original text, it includes footnotes by Alderson updating the material with new developments in number theory.

https://en.wikipedia.org/wiki/Consani%E2%80%93Scholten%20quintic | In the mathematical fields of algebraic geometry and arithmetic geometry, the Consani–Scholten quintic is an algebraic hypersurface (the set of solutions to a single polynomial equation in multiple variables) studied in 2001 by Caterina Consani and Jasper Scholten. It has been used as a test case for the Langlands program.
Definition
Consani and Scholten define their hypersurface from the (projectivized) set of solutions to the equation
in four complex variables, where
In this form the resulting hypersurface is singular: it has 120 double points. Its Hodge diamond is
The Consani–Scholton quintic itself is the non-singular hypersurface obtained by blowing up these singularities. As a non-singular quintic threefold, it is a Calabi–Yau manifold.
Modularity
According to the Langlands program, for any Calabi–Yau threefold over , the Galois representations giving the action of the absolute Galois group on the -adic étale cohomology (for prime numbers of good reduction, which for this curve means any prime other than 2, 3, or 5) should have the same L-series as an automorphic form. This was known for "rigid" Calabi–Yau threefolds, for which the family of Galois representations has dimension two, by the proof of Serre's modularity conjecture. The Consani–Scholton quintic provides a non-rigid example, where the dimension is four. Consani and Scholten constructed a Hilbert modular form and conjectured that its L-series agreed with the Galois representations for their curve; this was proven by .

She was president of the Simon Fraser University Faculty Association for two terms from 1994 to 1996, and again from 2004 to 2005.
Outreach
Dubiel is known for her studies of Canadian primary and secondary school mathematics textbooks, and for pointing out problems in these texts caused in part because they were written by education professionals without consulting any mathematicians. Although she values creativity imagination in mathematics, and uses it in her own lessons, she has also stated that it "must not come at the expense of basic math skills, clear instructions and practice".
She has also served as president of the Canadian Math Education Study Group and co-chair in 2009 of the Canadian Mathematics Education Forum. She is the founder of an annual mathematics workshop for female graduate students in mathematics, Connecting Women in Mathematics Across Canada. She organizes the annual Changing the Culture conference for mathematics teachers at the Pacific Institute for the Mathematical Sciences, and is the creator of a series of exhibits and activities about mathematics in British Columbia shopping centers. She also leads multiple programs for high school mathematics.
Recognition
Dubiel became a 3M Canadian National Fellow for Teaching and Learning in Higher Education in 2008. The award citation noted her exceptional ability to instill mathematical confidence in entering students, her creative use of cartoons and fairy-tale stories to foster students' mathematical imagination, and her work publicizing mathematics and numeracy to the public.
She was the 2011 recipient of the Adrien Pouliot Award of the Canadian Mathematical Society for her contributions to mathematics education in Canada.
She also won a 2011 YWCA Women of Distinction award.
In 2018 the Canadian Mathematical Society listed her in their inaugural class of fellows.

https://en.wikipedia.org/wiki/Pamela%20Gorkin | Pamela Gorkin is an American mathematician specializing in complex analysis and operator theory. She is a professor of mathematics at Bucknell University.
Education and career
Gorkin earned bachelor's and master's degrees in statistics from Michigan State University in 1976. She then shifted to pure mathematics for her doctoral studies, completing her Ph.D. at Michigan State in 1982, the same year she joined the Bucknell Faculty. Her dissertation, Decompositions of the Maximal Ideal Space of L, was supervised by Sheldon Axler.
At Bucknell, she was Presidential Professor from 2001 to 2004.
Books
With Ulrich Daepp, Gorkin is the author of the undergraduate textbook Reading, Writing, and Proving: A Closer Look at Mathematics (Springer, 2003; 2nd ed., 2011).
With Daepp, Andrew Shaffer, and Karl Voss, she is the author of Finding Ellipses: What Blaschke Products, Poncelet’s Theorem, and the Numerical Range Know about Each Other (Carus Mathematical Monographs, MAA Press, 2018). The book studies a connection between Blaschke products, Poncelet's closure theorem, and the numerical range of matrices. A Blaschke product is a certain kind of mapping of the unit disk in the complex plane to itself, and the ones considered in the first part of the book have order three (they map the unit circle three-to-one to itself, so that each point on the unit circle has three preimages). These triples of preimages form triangles that are all inscribed in the unit circle, and (it turns out) they all circumscribe an ellipse. Thus, they form an infinite system of polygons inscribed in and circumscribing two conics, as Poncelet's theorem describes. The ellipse is the boundary of the numerical range of a certain matrix derived from the Blaschke product, a region within which the eigenvalues of the matrix can be found, and in this case the eigenvalues are at the foci of the ellipse. The book tells "a story of discovery" outlining these connections, extends similar results to Blaschke products of higher order, and outlines a plan for further research in this area.
Recognition
Gorkin was the 2018 AWM/MAA Falconer Lecturer. Her lecture was on "Finding Ellipses", the topic of one of her books. She is also the recipient of Bucknell's Lindback Award for Distinguished Teaching, and the Crawford Distinguished Teaching Award of the Mathematical Association of America.

https://en.wikipedia.org/wiki/An%20Introduction%20to%20the%20Philosophy%20of%20Mathematics | An Introduction to the Philosophy of Mathematics is a 2012 textbook on the philosophy of mathematics by Mark Colyvan. It has a focus on issues in contemporary philosophy, such as the mathematical realism–anti-realism debate and the philosophical significance of mathematical practice, and largely skips over historical debates. It covers a range of topics in contemporary philosophy of mathematics including various forms of mathematical realism, the Quine–Putnam indispensability argument, mathematical fictionalism, mathematical explanation, the "unreasonable effectiveness of mathematics", paraconsistent mathematics, and the role of mathematical notation in the progress of mathematics. The book was praised as accessible and well-written and the reaction to its contemporary focus was largely positive, although some academic reviewers felt that it should have covered the historical debates over logicism, formalism and intuitionism in more detail. Other aspects of the book that received praise were its coverage of mathematical explanation, its appeal to mathematicians and other non-philosophers, and its discussion questions and further readings, whilst its epilogue and short length received a more mixed reception.
Overview
An Introduction to the Philosophy of Mathematics is a textbook on the philosophy of mathematics focusing on the issue of mathematical realism, i.e. the question of whether or not there are mathematical objects, and mathematical explanation. Colyvan described his intention for the book as being a textbook that "[gets] beyond the first half of the twentieth century and [explores] the issues capturing the attention of contemporary philosophers of mathematics". As a result, the book focuses less on historical debates in the philosophy of mathematics than other similar textbooks and more on contemporary issues, including the philosophy of mathematical practice.
Summary
The book has eight chapters and an epilogue with each chapter ending with a list of discussion questions and further readings. Chapter 1 briefly covers what Colyvan calls the "big isms" which dominated early 20th century philosophy of mathematics: logicism, formalism and intuitionism. It then turns to the philosophical issues raised by Paul Benacerraf in his papers "What is Mathematical Truth?" (1965) and "What Numbers Could Not Be" (1971).
Chapter 2 concerns the limits of mathematics and relevant constraining mathematical theorems. It discusses the Löwenheim–Skolem theorem and its connection with Cantor's theorem, including a proof of Cantor's theorem and an explanation of why the two theorems are not contradictory. It also discusses Gödel's incompleteness theorems and Gödel and Cohen's work on the independence of the continuum hypothesis. These results are used to motivate the debate between mathematical realism and anti-realism.
Following Hilary Putnam, Colyvan distinguishes between realism about mathematical truths and realism about mathematical objects in chapter |
https://en.wikipedia.org/wiki/Gan%E2%80%93Gross%E2%80%93Prasad%20conjecture | In mathematics, the Gan–Gross–Prasad conjecture is a restriction problem in the representation theory of real or p-adic Lie groups posed by Gan Wee Teck, Benedict Gross, and Dipendra Prasad. The problem originated from a conjecture of Gross and Prasad for special orthogonal groups but was later generalized to include all four classical groups. In the cases considered, it is known that the multiplicity of the restrictions is at most one
and the conjecture describes when the multiplicity is precisely one.
Motivation
A motivating example is the following classical branching problem in the theory of compact Lie groups. Let be an irreducible finite dimensional representation of the compact unitary group , and consider its restriction to the naturally embedded subgroup . It is known that this restriction is multiplicity-free, but one may ask precisely which irreducible representations of occur in the restriction.
By the Cartan–Weyl theory of highest weights, there is a classification of the irreducible representations of via their highest weights which are in natural bijection with sequences of integers .
Now suppose that has highest weight . Then an irreducible representation of with highest weight occurs in the restriction of to (viewed as a subgroup of ) if and only if and are interlacing, i.e. .
The Gan–Gross–Prasad conjecture then considers the analogous restriction problem for other classical groups.
Statement
The conjecture has slightly different forms for the different classical groups. The formulation for unitary groups is as follows.
Setup
Let be a finite-dimensional vector space over a field not of characteristic equipped with a non-degenerate sesquilinear form that is -Hermitian (i.e. if the form is Hermitian and if the form is skew-Hermitian). Let be a non-degenerate subspace of such that and is of dimension . Then let , where is the unitary group preserving the form on , and let be the diagonal subgroup of .
Let be an irreducible smooth representation of and let be either the trivial representation (the "Bessel case") or the Weil representation (the "Fourier–Jacobi case").
Let be a generic L-parameter for , and let be the associated Vogan L-packet.
Local Gan–Gross–Prasad conjecture
If is a local L-parameter for , then
Letting be the "distinguished character" defined in terms of the Langlands–Deligne local constant, then furthermore
Global Gan–Gross–Prasad conjecture
For a quadratic field extension , let where is the global L-function obtained as the product of local L-factors given by the local Langlands conjectures.
The conjecture states that the following are equivalent:
The period interval is nonzero when restricted to .
For all places , the local Hom space and .

https://en.wikipedia.org/wiki/The%20Indispensability%20of%20Mathematics | The Indispensability of Mathematics is a 2001 book by Mark Colyvan in which he examines the Quine–Putnam indispensability argument in the philosophy of mathematics. This thesis is based on the premise that mathematical entities are placed on the same ontological foundation as other theoretical entities indispensable to our best scientific theories.

https://en.wikipedia.org/wiki/Quine%E2%80%93Putnam%20indispensability%20argument | The Quine–Putnam indispensability argument is an argument in the philosophy of mathematics for the existence of abstract mathematical objects such as numbers and sets, a position known as mathematical platonism. It was named after the philosophers Willard Quine and Hilary Putnam, and is one of the most important arguments in the philosophy of mathematics.
Although elements of the indispensability argument may have originated with thinkers such as Gottlob Frege and Kurt Gödel, Quine's development of the argument was unique for introducing to it a number of his philosophical positions such as naturalism, confirmational holism, and the criterion of ontological commitment. Putnam gave Quine's argument its first detailed formulation in his 1971 book Philosophy of Logic. He later came to disagree with various aspects of Quine's thinking, however, and formulated his own indispensability argument based on the no miracles argument in the philosophy of science. A standard form of the argument in contemporary philosophy is credited to Mark Colyvan; whilst being influenced by both Quine and Putnam, it differs in important ways from their formulations. It is presented in the Stanford Encyclopedia of Philosophy:
We ought to have ontological commitment to all and only the entities that are indispensable to our best scientific theories.
Mathematical entities are indispensable to our best scientific theories.
Therefore, we ought to have ontological commitment to mathematical entities.
Nominalists, philosophers who reject the existence of abstract objects, have argued against both premises of this argument. An influential argument by Hartry Field claims that mathematical entities are dispensable to science. This argument has been supported by attempts to demonstrate that scientific and mathematical theories can be reformulated to remove all references to mathematical entities. Other philosophers, including Penelope Maddy, Elliott Sober, and Joseph Melia, have argued that we do not need to believe in all of the entities that are indispensable to science. The arguments of these writers inspired a new explanatory version of the argument, which Alan Baker and Mark Colyvan support, that argues mathematics is indispensable to specific scientific explanations as well as whole theories.
Background
In his 1973 paper "Mathematical Truth", raised a problem for the philosophy of mathematics. According to Benacerraf, mathematical sentences such as "two is a prime number" seem to imply the existence of mathematical objects. He supported this claim with the idea that mathematics should not have its own special semantics, or in other words, the meaning of mathematical sentences should follow the same rules as non-mathematical sentences. For example, according to this reasoning, if the sentence "Mars is a planet" implies the existence of the planet Mars, then the sentence "two is a prime number" should also imply the existence of the number two. But according to Benacerr |
https://en.wikipedia.org/wiki/Mary%20Shore%20Walker | Mary Shore Walker (1882–1952) was the first woman faculty member at the University of Missouri, and taught in the department of Mathematics.
She was born in 1882. She earned her B.A. and M.A. at the University of Missouri in 1903 and 1904, respectively. The thesis she wrote for her M.A. was titled, "On finite groups with special reference to Klein’s ikosaeder.” While at the University of Missouri, she studied with Earle Hedrick, Oliver Dimon Kellogg, and W.

https://en.wikipedia.org/wiki/Johanna%20Piesch | Johanna (Hansi) Camilla Piesch (1898–1992) was an Austrian librarian, physicist and mathematician who is remembered for the pioneering contributions she made to switching algebra, one of the fundamentals of digital computing and programming languages.
Biography
Born on 6 June 1898 in Innsbruck, Johanna Camilla Piesch was the daughter of Oswald Piesch, a cavalry officer. She was brought up in Vienna where after primary school, she attended secondary school at the Reform Realgymnasium Dr. Wesely, matriculating in 1916. She went on to study physics at the University of Vienna, earning a doctorate in 1921. In addition, she received a teaching qualification in mathematics and physics in 1928.
She joined the Post and Telegraph Service (Post- und Telegraphenverwaltung) in 1928, but had to take up early retirement in 1938 under the National Socialist regime. In July 1945, she was able to return to work, heading the PTT's laboratory. In February 1956, she moved to the library of the Technical University's documentation centre for technology and science. She retired in October 1962.
It appears that after leaving her post in 1938, Piesch was sent to Berlin, where she began to work on switching algebra. This is supported by her publications on Boolean algebra in 1939, making her the first person to address its applications. In so doing, she paved the way for the Austrian mathematicians Adalbert Duschek and Otto Plechl who later undertook work on switching algebra. The simplification method put forward in her second publication is of particular note.
The last 30 years of Piesch's life were devoted to social work. She died on 28 September 1992 in Vienna.
Her work is widely considered of significance to the development of computer science.

https://en.wikipedia.org/wiki/Sofia%20Danova | Sofia Danova (née Simeonova; born 1879 in Veliko Tarnovo; and died in 1946) was a Bulgarian philanthropist, educator and publisher. She was the first Bulgarian woman to graduate in mathematics.
Life
Danova's father had been a Russian feldsher in the Russo-Turkish War (1877–1878) who settled in Bulgaria when he met his future wife. Sofia had a sister Olya. She graduated from the Metropolitan Clement Girls' High School in Veliko Tarnovo. She then went to Russia to attend the Saint Petersburg State Institute of Technology from where she obtained a degree in mathematics. Between 1904 and 1907, she taught mathematics at the Plovdiv Girls' Gymnasium. She married Gruyo Danov, a son of Hristo G. Danov, a publisher, in 1907. She also was active in the family publishing house after her father-in-law's death in 1911, along with her husband and brother-in-law. They published around 2,400 books by 1947 when the publishing house was dissolved.
She died in 1946.
Charity
In 1936, Sofia headed a women's charitable foundation to support the education of poor students. The foundation, established in 1895, aimed at the economic independence of girls by training them in a vocation. A range of subjects were taught, including embroidery, tailoring, art and draughtsmanship. In 1910, the school library was set up with books donated by Hristo Danov. A fund in Sofia's name was established as well, which by 1946 had a capital of 31,690 lev. This was responsible for the welfare of poor students as well as the construction of housing.

https://en.wikipedia.org/wiki/Rozetta%20Zhilina | Rozetta Andreyevna Zhilina (; 8 June 1933, Leningrad – 11 December 2003, Snezhinsk) was a Soviet and Russian mathematician and computer scientist.
Education
She graduated from the Mathematics and Mechanics department of the Leningrad State University in 1956, where one of her classmates was Anatoly Vershik.
Career
She worked at the All-Russian Scientific Research Institute Of Technical Physics in the mathematical section.
After World War II, the Soviet Union began an ambitious program to develop their own computing technology, creating systems to rival those in the United States. Computer science research was often kept secret during the ongoing Cold War, but was seen as an important field nonetheless. From the 1960s to the 1980s, women represented half of the students in this area in Soviet universities and they later went on to work in the field, either as programmers or system designers.
Zhilina developed algorithms and computer programs for solving problems in physics, mechanics and the non-stationary thermal conductivity of complex nuclear weapons. Under her leadership, computer programs were developed to solve problems in the field of optimal trajectories of nuclear weapons, including their ballistics.
Awards and honours
She was a laureate of the USSR State Prize (1988), the Medal "For Labour Valour" (1962) and the Order of the Red Banner of Labour (1975).
Death
Zhilina died in Snezhinsk in 2003, and is interred in the town cemetery.

https://en.wikipedia.org/wiki/Lianne%20Sheppard | Elizabeth Anne (Lianne) Sheppard is an American statistician. She specializes in biostatistics and environmental statistics, and in particular in the effects of air quality on health. She is a Professor of Environmental and Occupational Health Sciences and a Professor of Biostatistics in the University of Washington School of Public Health. In 2021, Dr. Sheppard was named to the Rohm & Haas Endowed Professorship of Public Health Sciences.
Education
Dr. Sheppard graduated from Johns Hopkins University with a bachelor's degree in psychology in 1979, and returned to Johns Hopkins for a master's degree in biostatistics in 1985. She completed her Ph.D. in biostatistics in 1992 at the University of Washington. Her dissertation, Aggregate Data Methods for Relative Risk Parameter Estimation in Diet and Disease Prevention Research, was supervised by Ross L. Prentice.
Research contributions
Dr. Sheppard's methodological research interests are observational study methods, exposure modeling, study design, and epidemiology. Her applied research focuses on the health effects of occupational and environmental exposures. She is principal investigator of the NIH-funded training grant Biostatistics, Epidemiologic & Bioinformatics Training in Environmental Health, and she oversees the SURE-EH training program, a project to promote diversity in the environmental health sciences. She is also co-principal investigator of the NIH-funded Adult Changes in Thought Air Pollution study and of a Health Effects Institute study to better understand the role of exposure assessment design and modeling in inference about air pollution health effects.
She has published over 190 peer-reviewed publications. Among her principal methodological/statistical contributions to the environmental health field are 1) developing statistical methods for aggregate data studies; 2) developing measurement error correction methods for inference about health effects for applications to air pollution cohort studies; 3) advancements in spatial and spatio-temporal modeling methods for air pollution exposures; and 4) referent selection and analysis approaches for case-crossover study design for air pollution epidemiology. She has also helped advance scientific understanding of the adverse effects of a variety of environmental exposures, including air pollution, noise, manganese, and pesticides.
Policy Contributions
In 2016, Dr. Sheppard was chosen to chair a panel of the United States Environmental Protection Agency to examine in what quantities nitrogen oxides are harmful. However, in 2018 the Trump administration replaced Dr. Sheppard and other academic experts on the panel with public health officials, at the same time disbanding a related panel on particulate pollution. Dr. Sheppard was quoted as saying that these changes would "result in poorer-quality scientific oversight". Dr. Sheppard is also a participant in a lawsuit against new agency rules preventing scientists funded by the agency from |
https://en.wikipedia.org/wiki/Jean%20Pedersen | Jean J. Pedersen (Sep 17, 1934–Jan 1, 2016) was an American mathematician and author particularly known for her works on the mathematics of paper folding.
Education and career
Pedersen was born in Salt Lake City, Utah, the daughter of an ophthalmologist and a teacher. She studied home economics changing to a double major in mathematics and physics as an undergraduate at Brigham Young University, before becoming a graduate student in mathematics at the University of Utah under the supervision of E. Allen Davis.
After completing her master's degree, she moved to San Jose, California, following her husband who worked for IBM. She joined the faculty at the Santa Clara University on a part-time basis in 1966, but shifted to full-time and was promoted to full professor in 1996. She was the first woman to teach mathematics at the university, and the first to be tenured as a mathematics professor.
Her discovery that the platonic solids could be braided from strips of paper led to Martin Gardner writing about it in the September, 1971 Mathematical Games column in Scientific American.

Pedersen's books include:
Geometric Playthings (With Kent Pedersen, Dale Seymour Publications Secondary, 1973, )
Fear No More: An Adult Approach to Mathematics (with Peter Hilton, Dale Seymour Publications, 1982 )
