https://en.wikipedia.org/wiki/Robert%20F.%20Tichy | Robert Franz Tichy (born 30 September 1957 in Vienna) is an Austrian mathematician and professor at Graz University of Technology.
He studied mathematics at the University of Vienna and finished 1979 with a Ph.D. thesis on uniform distribution under the supervision of Edmund Hlawka. He received his habilitation at TU Wien in 1983. Currently he is a professor at the Institute for Analysis and Number Theory at TU Graz. Previous positions include head of the Department of Mathematics and Dean of the Faculty of Mathematics, Physics and Geodesy at TU Graz, President of the Austrian Mathematical Society, and Member of the Board (Kuratorium) of the FWF, the Austrian Science Foundation.
His research deals with Number theory, Analysis and Actuarial mathematics, and in particular with number theoretic algorithms, digital expansions, diophantine problems, combinatorial and asymptotic analysis, quasi Monte Carlo methods and actuarial risk models.
Among his contributions are results in discrepancy theory, a criterion (joint with Yuri Bilu) for the finiteness of the solution set of a separable diophantine equation, as well as investigations of graph theoretic indices and of combinatorial algorithms with analytic methods.
He also investigated (with Istvan Berkes and Walter Philipp) pseudorandom properties of lacunary sequences.
In the theory of equidistribution he solved (with Harald Niederreiter) an open problem of Donald Knuth's book The Art of Computer Programming, by showing that for any sequence of distinct natural numbers the sequence is completely uniformly distributed for almost all real numbers ; as a corollary, for almost all real numbers the sequence is random in the sense of Knuth's definition R4.
Tichy is interested in the history of Alpinism and is also an avid climber.
In 1985 he received the Prize of the Austrian Mathematical Society. Since 2004 he has been a Corresponding Member of the Austrian Academy of Sciences. In 2017 he received an honorary doctorate from the University of Debrecen. He taught as a visiting professor at the University of Illinois at Urbana–Champaign and the Tata Institute of Fundamental Research. In 2017 he was a guest professor at Paris 7; in the winter semester 2020/21 he held the
Morlet chair at the Centre International de Rencontres Mathématiques in Luminy.

https://en.wikipedia.org/wiki/Teri%20Perl | Teri Perl (born November 19, 1926) is an American mathematics educator, author of mathematics resource books, and a co-founder of The Learning Company.
Education and career
Perl was born in New York City, New York. In 1947, she received a bachelor's degree in economics from Brooklyn College in New York. She did post-baccalaureate work at San Jose State University in California and earned a secondary mathematics teaching credential there in 1969. While doing substitute teaching in the San Francisco Bay Area, Perl discovered that there weren't adequate resources for substitute teachers. She began a long-distance collaboration with Miriam K. Freedman to produce A Sourcebook for Substitutes and Other Teachers. Freedman developed the material for teachers of English, foreign languages, and social science and Perl for teachers of mathematics and science. Perl was a mathematics consultant and resource teacher at Ventura Elementary School in Palo Alto, California from 1971 to 1978.
After her youngest child was in high school, Perl attended Stanford University in Palo Alto, California and obtained a Ph.D. in mathematics education in 1979. The title of her dissertation was "Discriminating Factors and Sex Differences in Electing Mathematics". From 1971 to 1979, while working on her doctorate at Stanford, Perl taught part-time at San Francisco State University.
In 1980, Perl, Ann McCormick, Leslie Grimm, and Warren Robinett founded The Learning Company (TLC), an educational software company that developed grade-based learning software, as well as edutainment games and productivity tools. Perl was the content designer for TLC's Math Rabbit. She was responsible for writing users'/teachers' guides to accompany several software packages produced by TLC. In 1995, TLC was taken over by SoftKey, who changed their name to The Learning Company. After several sales, The Learning Company brand was used by Houghton Mifflin Harcourt through 2018.
In 1974, Perl, together with a group of San Francisco Bay area women, founded the Math/Science Network to encourage and inspire middle and high school girls to pursue careers in STEM. The network was rebranded as the Expanding Your Horizons (EYH) Network in 1982 when EYH obtained nonprofit status. The MSN/EYH developed a one-day workshop for middle and high school girls with hands-on workshops and interactions with women in STEM careers. Perl served as president of the EYH Network from 1999 to 2007. EYH has run over 80 Career Days, with up to 25,000 girls participating each year. In 2010, the EYH Network was honored by the National Science Board with their Public Service Award "for its decades-long commitment to the early development of interest in mathematics and science among young women, making significant strides toward its goal to develop a pool of qualified women to undertake careers in mathematics, science and engineering."

https://en.wikipedia.org/wiki/Murasugi%20sum | In algebraic topology, a Murasugi sum is a function that relates a finite sequence of surfaces over a disk, which is common to every parallel pair (adjacent), in such a way that it exists in the boundaries of a closed arc. The only place that they are disjoint is at their endpoints, which are also alternating subarcs between the two surfaces' boundaries.
Etymology
Murasugi sums are named after Kunio Marasugi.
Uses
Murasugi sums are primarily a topic of pure mathematics. Murasugi sums can be applied to rather diverse subjects, like most mathematical topics.

Biography
McElwain gained her BA from Wilson College in 1895. She subsequently taught Greek, English, and maths at the college until 1903.
After teaching at a finishing school ('Miss Wright's School') at Bryn Mawr until 1908 McElwain gained a MA from Cornell University in 1909 with a thesis titled "The Life of the Empress Livia Based on Latin and Greek Sources" and her PhD in 1910 on "The use of the imperative in Plautus". In 1936 she was awarded an honorary Litt. D. from Wilson College.
From 1910 until her retirement in 1942, McElwain taught Latin and Greek at Smith College. She served as class dean three times and was made Professor Emeritus of Classical Languages and Literature.
She returned to Wilson College after retirement and worked as the acting dean until 1946 and as the college historian. She had previously served on the board of trustees of Wilson College from 1929 to 1932 and 1938–56.
McElwain was a member of Phi Beta Kappa, American Academy in Rome, American Philological Association, and the American Association of University Women.
McElwain is buried at Cedar Grove Cemetery in Chambersburg. A hall of residence at Wilson College is named after her.

https://en.wikipedia.org/wiki/Sequence%20covering%20map | In mathematics, specifically topology, a sequence covering map is any of a class of maps between topological spaces whose definitions all somehow relate sequences in the codomain with sequences in the domain. Examples include maps, , , and . These classes of maps are closely related to sequential spaces. If the domain and/or codomain have certain additional topological properties (often, the spaces being Hausdorff and first-countable is more than enough) then these definitions become equivalent to other well-known classes of maps, such as open maps or quotient maps, for example. In these situations, characterizations of such properties in terms of convergent sequences might provide benefits similar to those provided by, say for instance, the characterization of continuity in terms of sequential continuity or the characterization of compactness in terms of sequential compactness (whenever such characterizations hold).
Definitions
Preliminaries
A subset of is said to be if whenever a sequence in converges (in ) to some point that belongs to then that sequence is necessarily in (i.e. at most finitely many points in the sequence do not belong to ). The set of all sequentially open subsets of forms a topology on that is finer than 's given topology
By definition, is called a if
Given a sequence in and a point in if and only if in Moreover, is the topology on for which this characterization of sequence convergence in holds.
A map is called if is continuous, which happens if and only if for every sequence in and every if in then necessarily in
Every continuous map is sequentially continuous although in general, the converse may fail to hold.
In fact, a space is a sequential space if and only if it has the following :
for every topological space and every map the map is continuous if and only if it is sequentially continuous.
The in of a subset is the set consisting of all for which there exists a sequence in that converges to in
A subset is called in if which happens if and only if whenever a sequence in converges in to some point then necessarily
The space is called a if for every subset which happens if and only if every subspace of is a sequential space.
Every first-countable space is a Fréchet–Urysohn space and thus also a sequential space. All pseudometrizable spaces, metrizable spaces, and second-countable spaces are first-countable.
Sequence coverings
A sequence in a set is by definition a function whose value at is denoted by (although the usual notation used with functions, such as parentheses or composition might be used in certain situations to improve readability).
Statements such as "the sequence is injective" or "the image (i.e. range) of a sequence is infinite" as well as other terminology and notation that is defined for functions can thus be applied to sequences.
A sequence is said to be a of another sequence if there exists a strictly increasin |

https://en.wikipedia.org/wiki/2021%20population%20census%20in%20Hong%20Kong | The 2021 population census (21C) in Hong Kong was conducted by the Census and Statistics Department (C&SD) of the HKSAR Government during 23 June to 4 August 2021. The 21C was conducted under the Census and Statistics (2021 Population Census) Order, which was made by the Chief Executive in Council under Section 9 of the Census and Statistics Ordinance (Cap 316). The Order, published in the Gazette on 16 October 2020, provided statutory backing for the conduct of the 21C.
The 21C comprised a simple enumeration on about nine-tenths of households in Hong Kong to provide basic information (e.g. year and month of birth and sex) and a detailed enquiry on the remaining one-tenth on a broad range of demographic and socio-economic characteristics. Therefore, two types of questionnaire, namely the "Short Form" and the "Long Form", were used.
The "Short Form", which was used in the simple enumeration, covered only some basic questions. On the other hand, the "Long Form", which was used in the detailed sample enquiry, included not only those questions covered in the "Short Form", but also additional ones related to the socio-economic characteristics of the population and the characteristics of households and quarters. Taking together the common information collected in both the "Short Form" and "Long Form" would give the complete enumeration results on the basic characteristics of the population. It would also form the basis for estimation of the detailed socio-economic characteristics collected through the "Long Form".
Slogans and mascots
Two slogans were adopted to promote the importance of the 21C and encourage households to use online questionnaires:
2021 Census: Provide Data for Hong Kong's Future
Online Census: Convenient, Secure and Green
Two mascots were also created to help disseminate publicity messages to the public, "Paul", and "Charlotte".
Paul: Charlotte:
Data topics
Notes
Items with * are those included in the "Short-Form" questionnaire. For the "Long-Form" questionnaire, all the above data topics are included (a total of 46 items).
Data collection methods
A multi-modal data collection approach was used in the 21C.
In the first phase, all households might provide the required information through the following means:
online questionnaire;
postal questionnaire with pre-paid return envelope ("Short Form" only); and
telephone interview via the hotline 18 2021.
In the second phase of data collection, C&SD would arrange census officers to visit households that had not yet provided their information, and use mobile tablets to collect the required information.
Besides, for households residing on fishing boats, their number was estimated based on aerial photos of all anchorages in Hong Kong Waters and their characteristics estimated based on information provided by the Agriculture, Fisheries and Conservation Department. As for households residing on pleasure craft, notification letters were sent to the sampled households to in |

Meaning: All the extant things in three worlds can’t exist without their foundation being in mathematics.
The end of the first chapter Sangyaādhikāra describes the following eight qualities of a mathematician:
लघुकरणोहापोहानालस्यग्रहणधारणोपायैः।
व्यक्तिकरांकविशिष्टैर् गणकोऽष्टाभिर् गुणैर् ज्ञेयः॥
Meaning: A mathematician is to be known by eight qualities: conciseness, inference, confutation, vigour in work and progress, comprehension, concentration of mind and by the ability of finding solutions and uncovering quantities by investigation.

https://en.wikipedia.org/wiki/2021%20Nepal%20census | The 2021 Nepal Census was the twelfth nationwide census of Nepal conducted by the Central Bureau of Statistics. The census was originally scheduled from 8 June to 22 June 2021, but was postponed to November 2021 due to surge in COVID-19 cases.
Background
In Nepal, the work of conducting a census started in 1911 A.D. (1968 B.S.) and has been carried out approximately every 10/10 years. The main objective of the first and second census was to prepare a list of property owners, tenants, and buildings. Until the census conducted in 1998 B.S., it was limited to the form of a short census questionnaire. However, the censuses conducted since 2009/11 B.S. (1952/54 A.D.) have been recognized as modern (scientific) censuses, including the collection of demographic characteristics. After the establishment of the Central Bureau of Statistics in 2015 A.D., all censuses have been conducted by this bureau. In this sequence, the national census of 2078 B.S. is the first census conducted under Nepal's federal system according to the provisions of the Constitution of Nepal issued in 2072 B.S.
Planning
The National Census of 2078 was conducted in two phases, with the first phase being carried out by supervisors who went to every home and family and prepared a household registration form, detailing information about the house and household, the number of members in the family, the family's agriculture-related details, whether the family had received government funding for building a residential house, the number of individuals who had bank or financial institution accounts, and details about technical and vocational education or training received by members of the family, as well as information about credit facilities obtained from cooperative or financial institutions.
In the second phase, enumerators went to every family and collected information about demographic, educational, residential, economic, disability, reproductive health, and other details using a main questionnaire. During the second phase, detailed monitoring of the collection of site-specific data was carried out by the supervisor, and each ward office collected ward-level community questionnaire-based information on the basis of sources, resources, capacity, precedent, and disaster risk.

https://en.wikipedia.org/wiki/Metalog%20distribution | The metalog distribution is a flexible continuous probability distribution designed for ease of use in practice. Together with its transforms, the metalog family of continuous distributions is unique because it embodies all of following properties: virtually unlimited shape flexibility; a choice among unbounded, semi-bounded, and bounded distributions; ease of fitting to data with linear least squares; simple, closed-form quantile function (inverse CDF) equations that facilitate simulation; a simple, closed-form PDF; and Bayesian updating in closed form in light of new data. Moreover, like a Taylor series, metalog distributions may have any number of terms, depending on the degree of shape flexibility desired and other application needs.
Applications where metalog distributions can be useful typically involve fitting empirical data, simulated data, or expert-elicited quantiles to smooth, continuous probability distributions. Fields of application are wide-ranging, and include economics, science, engineering, and numerous other fields. The metalog distributions, also known as the Keelin distributions, were first published in 2016 by Tom Keelin.
History
The history of probability distributions can be viewed, in part, as a progression of developments towards greater flexibility in shape and bounds when fitting to data. The normal distribution was first published in 1756, and Bayes’ theorem in 1763. The normal distribution laid the foundation for much of the development of classical statistics. In contrast, Bayes' theorem laid the foundation for the state-of-information, belief-based probability representations. Because belief-based probabilities can take on any shape and may have natural bounds, probability distributions flexible enough to accommodate both were needed. Moreover, many empirical and experimental data sets exhibited shapes that could not be well matched by the normal or other continuous distributions. So began the search for continuous probability distributions with flexible shapes and bounds.
Early in the 20th century, the Pearson family of distributions, which includes the normal, beta, uniform, gamma, student-t, chi-square, F, and five others, emerged as a major advance in shape flexibility. These were followed by the Johnson distributions. Both families can represent the first four moments of data (mean, variance, skewness, and kurtosis) with smooth continuous curves. However, they have no ability to match fifth or higher-order moments. Moreover, for a given skewness and kurtosis, there is no choice of bounds. For example, matching the first four moments of a data set may yield a distribution with a negative lower bound, even though it might be known that the quantity in question cannot be negative. Finally, their equations include intractable integrals and complex statistical functions, so that fitting to data typically requires iterative methods.
Early in the 21st century, decision analysts began working to develop contin |

https://en.wikipedia.org/wiki/Ambar%20Sengupta | Ambar Niel Sengupta is an Indian-American mathematician. He is a professor of mathematics at the University of Connecticut.
Education and career
Ambar Sengupta attended Presidency College, Calcutta and stood first class first in the BSc (Mathematics Honours) examination of the University of Calcutta in 1984. He then joined Cornell University, where he obtained an MS and then a PhD under the supervision of Leonard Gross in 1990.
After a post-doctoral appointment in the Physics Department of Princeton University, he joined Louisiana State University. He became a professor of mathematics in 2003, and he was awarded the Hubert Butts Alumni Professorship in 2011. Sengupta joined the Mathematics faculty of the University of Connecticut as Professor and Head of the Department in 2016.
Professional activities
Sengupta's contributions have been in the fields of pure mathematics, mathematical physics, and financial mathematics.
In quantum field theory, Sengupta gave the first rigorous construction of the Yang-Mills measure for compact surfaces, with or without boundary and for bundles of specified topology. He used this to mathematically prove formulas that had been used in the physics literature and discovered new formulas for non-trivial bundles. He gave a rigorous proof of Edward Witten's formula for the volume of the moduli space of flat connections on a compact oriented surface, and proved that the Yang-Mills measure converges to this limiting measure. He is an initiator of the rigorous study of the large-N limit of Yang-Mills theory in two dimensions. He and Michael Anshelevich showed that the limit of the U(N) Yang-Mills measure for the plane is described by free probability theory, confirming ideas initiated by I. M. Singer. He has published extensively in infinite-dimensional geometry and measure theory, as well as higher gauge theory.
He has served as doctoral advisor or co-advisor to 8 PhD students.
Ambar Sengupta is the founding Managing Editor of the Journal of Stochastic Analysis. He is a Council Member of the New England Statistical Society.
Awards and honors
Ambar Sengupta was awarded a Humboldt fellowship in 1995. He was named a Mercator Fellow by the Deutsche Forschungsgemeinschaft (German Research Foundation) in 2011; he was invited to a visiting professorship at the University of Bonn with this award.

https://en.wikipedia.org/wiki/Layer%20%28deep%20learning%29 | A layer in a deep learning model is a structure or network topology in the model's architecture, which takes information from the previous layers and then passes it to the next layer.
Layer Types
The first type of layer is the Dense layer, also called the fully-connected layer, and is used for abstract representations of input data. In this layer, neurons connect to every neuron in the preceding layer. In multilayer perceptron networks, these layers are stacked together.
The Convolutional layer is typically used for image analysis tasks. In this layer, the network detects edges, textures, and patterns. The outputs from this layer are then feed into a fully-connected layer for further processing. See also: CNN model.
The Pooling layer is used to reduce the size of data input.
The Recurrent Layer is used for text processing with a memory function. Similar to the Convolutional layer, the output of recurrent layers are usually fed into a fully-connected layer for further processing. See also: RNN model.
The Normalization layer adjusts the output data from previous layers to achieve a regular distribution. This results in improved scalability and model training.
Differences with layers of the neocortex
There is an intrinsic difference between deep learning layering and neocortical layering: deep learning layering depends on network topology, while neocortical layering depends on intra-layers homogeneity.

https://en.wikipedia.org/wiki/Trade%20data | Trade data, or import and export statistics, consist of statistical data about international trade, typically organized by time period, country, and commodity (using HS codes).
Uses
Governments, corporations, manufacturers, law firms, trade associations, and international organizations all use trade data to monitor the commodity markets relevant to their interests.
Trade data can be used to assess supply and demand for particular commodities in particular countries, which is useful not only to analysts but to companies seeking suppliers and customers.
Trade data can also reveal how international trade responds to, and has an impact on, world events such as the China–United States trade war and the COVID-19 pandemic
Trade data can reveal general trends in world trade and impact on particular regions and industries.
Trade data can inform government assessments of national trade partners and government regulatory decisions about international trade.
Data coverage and detail
Different sources of trade data may provide more or less complete data coverage, and more or less detail:
reported vs. mirrored: One key distinction in trade data is between the reporting country (the country that provides data) and the partner country (the country listed as an export partner or import partner in the data provided by a reporting country). Usually, the official sources of a reporting country provide the best data about the country's own imports and exports. If this information is not available, trade data analysts often rely on "mirrored" data: data about the country as a partner country listed by other reporting countries. In other words, analysts attempt to reconstruct information about a country's imports and exports based on what other countries have reported exporting to and importing from it. The disadvantages are that truly complete "mirrored" data would require data from every other country (not all countries provide trade data), and also that because of methodological differences, "country X’s reported exports to country Y rarely match country Y’s reported imports from country X."
countries, etc.: Different sources include different numbers of countries, because not all countries report trade data at all, and for many other countries trade data is not publicly available. Some sources provide trade data for groups of countries (such as the European Union), and some provide trade data for parts of countries (such as states in the United States and provinces in China).
commodity detail: HS codes for commodities are of different lengths, with shorter codes indicating broader categories of commodities and longer codes indicating more specific subcategories. The first two digits indicate the broadest categories of commodities (e.g., 01 indicates live animals), the first four digits indicate subcategories (e.g., 0101 indicates horses, donkeys, and their hybrids, mules and hinnies), and the first six digits indicate sub-subcategories (e.g., 010121 indicates pur |

https://en.wikipedia.org/wiki/Oka%E2%80%93Weil%20theorem | In mathematics, especially the theory of several complex variables, the Oka–Weil theorem is a result about the uniform convergence of holomorphic functions on Stein spaces due to Kiyoshi Oka and André Weil.
Statement
The Oka–Weil theorem states that if X is a Stein space and K is a compact -convex subset of X, then every holomorphic function in an open neighborhood of K can be approximated uniformly on K by holomorphic functions on (i.e. by polynomials).
Applications
Since Runge's theorem may not hold for several complex variables, the Oka–Weil theorem is often used as an approximation theorem for several complex variables. The Behnke–Stein theorem was originally proved using the Oka–Weil theorem.

https://en.wikipedia.org/wiki/Emily%20Coddington%20Williams | Emily Coddington Williams (born Emily Matilda Coddington, October 21, 1873 – August 8, 1952) was an American historian of mathematics, translator, novelist, playwright, and biographer.
Early life and education
Coddington was born on October 21, 1873, in New York City; her parents were of well-off colonial stock. Her father, a lawyer, died in 1876, and she came to live in Midtown Manhattan with her mother and grandmother. She passed the entrance examination for Harvard University in 1891, allowing her to study at the Harvard Annex, a precursor to Radcliffe College. Instead, she went to the University of London from 1894 to 1896, and earned a bachelor's degree there. In 1898, Columbia University awarded her a master's degree in mathematics, minoring in mechanics and Greek, based on a thesis she wrote at the end of her studies in London concerning the history of determinants.
She completed a Ph.D. at Columbia in 1905. Her dissertation, A Brief Account of the Historical Development of Pseudospherical Surfaces from 1827 to 1887, concerned the history of non-Euclidean geometry and the pseudosphere, also including material on a paper of Albert Victor Bäcklund on hyperbolic geometry, which she translated from Swedish into English.
Beginning in 1909 Coddington studied law at New York University, gaining admission to the bar in 1912 and earning a law degree in 1913. Although Coddington did not become a professional mathematician or lawyer, she remained a lifelong member of the American Mathematical Society, and attended the 1908 and 1912 International Congresses of Mathematicians in England and Italy, respectively.
Later life
Coddington married businessman William Henry Williams in 1917, and her subsequent publications were under the name Emily Coddington Williams. She participated in several clubs concerning gardening and women's suffrage, and traveled frequently to Europe. With her husband, she continued to live in New York, summering in Newport, Rhode Island. They were childless, although her husband had adopted Irma Williams, his niece, after Irma's mother died in childbirth in 1901.
Williams was the author of two one-act plays, Then (1914) and Pals (1925), two novels, Homing Pigeon (1927) and Quest for Love (1929) and a 1941 biography of William Coddington (1601–1678), governor of Rhode Island.
Her husband died in 1943. In 1952, Williams set sail for Europe on the RMS Queen Mary, but she broke her hip while on board, and died in a hospital in Paris on August 8, 1952, leaving a large legacy to her godchildren and the societies she belonged to. Her Newport estate, Villa Rosa, was sold to a real estate developer who demolished it and replaced it with a condominium complex.

Applications
In graph theory, the extended natural numbers are used to define distances in graphs, with being the distance between two unconnected vertices. They can be used to show the extension of some results, such as the max-flow min-cut theorem, to infinite graphs.
In topology, the topos of right actions on the extended natural numbers is a category PRO of projection algebras.
In constructive mathematics, the extended natural numbers are a one-point compactification of the natural numbers, yielding the set of non-increasing binary sequences i.e. such that .

https://en.wikipedia.org/wiki/Uniform%20boundedness%20conjecture%20for%20rational%20points | In arithmetic geometry, the uniform boundedness conjecture for rational points asserts that for a given number field and a positive integer that there exists a number depending only on and such that for any algebraic curve defined over having genus equal to has at most -rational points. This is a refinement of Faltings's theorem, which asserts that the set of -rational points is necessarily finite.
Progress
The first significant progress towards the conjecture was due to Caporaso, Harris, and Mazur. They proved that the conjecture holds if one assumes the Bombieri–Lang conjecture.
Mazur's Conjecture B
A variant of the conjecture, due to Mazur, asserts that there should be a number such that for any algebraic curve defined over having genus and whose Jacobian variety has Mordell–Weil rank over equal to , the number of -rational points of is at most . This variant of the conjecture is known as Mazur's Conjecture B.
Michael Stoll proved that Mazur's Conjecture B holds for hyperelliptic curves with the additional hypothesis that . Stoll's result was further refined by Katz, Rabinoff, and Zureick-Brown in 2015. Both of these works rely on Chabauty's method.
Mazur's Conjecture B was resolved by Dimitrov, Gao, and Habegger in a preprint in 2020 which has since appeared in the Annals of Mathematics using the earlier work of Gao and Habegger on the geometric Bogomolov conjecture instead of Chabauty's method.

https://en.wikipedia.org/wiki/Math%20Gran%20Prix | Math Gran Prix (released as Maths Grand Prix in Europe) is an educational video game written for the Atari 2600 by Suki Lee and published by Atari, Inc. in 1982.
Gameplay
The player must advance a car through a Grand Prix race by answering mathematics questions, with 9 variations of play. Random bonuses may pop up during play. Both two- and single-player gaming against the computer is possible, with the computer's calculation speed slowed artificially compared to its normal speed of calculation in single-player mode. Questions included addition, subtraction, multiplication, and division. The game is aimed at 7- to 10-year-old children.
Development
The game was programmed by Suki Lee. Lee went on to work on Obelix, also for the Atari 2600. The cover art for the game was drawn by Warren Chang.
Reception
In a January 1983, review the British computer games magazine TV Gamer described the game as "certainly a lot more entertaining than its predecessor, Basic Maths". A review in the January 1983 edition of Tilt magazine, a French video games magazine, gave the game 2/6 for graphics and 4/6 for interest, saying that the game might even be of interest to adults.
Reviewing the game in 2017 in the book The A-Z of Atari 2600 Games: Volume 2, Kieren Hawken described the game as "nothing more than a curio. An ugly and very unexciting curio at that!" and gave the game 3/10 overall.
Menno Deen, in a PhD thesis for the Eindhoven University of Technology, cited Math Gran Prix as "an example of the restrictive nature of early edutainment titles of the 80s", stating that the game's lack of player autonomy does not impart motivation to learn. He furthermore stated that Math Gran Prix and other mathematics edutainment games: "adopt the instructional model of the explainer and instructor, focusing on skill mastery and correct performances" rather than facilitating experimentation or exploration, the latter two of which he argued are more conducive to learning.

https://en.wikipedia.org/wiki/Measurement%20dysfunction | Measurement dysfunction describes a situation or behavior where actual data metrics, statistics and especially their meaning (or communicated meaning), can become problematic due to misuse. Specifically, in areas such as Human Resources (Performance measurements), Technology (Safety), Finance or Health, measurement dysfunctionality are critical, as it can lead to negative outcomes, wrong predictions or forecasts.
Practices to avoid:
Reward of wrong behavior (also persons who manipulate)
Measuring the wrong things
Measuring either not enough or too much
Cheating or data manipulation (intentional or unintentional due to wrong calculation models, systematic errors, human errors, etc.)
On eliminating dysfunctional measurement:
Establish, and monitor the move to and adherence to ‘policies’ for good, functional measurement
Support technical correctness
Periodically evaluate the information need and value delivered by measurements
Trivia
"What gets measured gets manipulated."

Itsenäisyydenkatu (literally "Independence Street") is an east–west street in the center of Tampere, Finland. It is a significant street connection in the city center of Tampere in terms of transport connections, as it leads from Tampere's railway station to the Liisankallio district in the Tammela district. On the west side of the station, the street continues as the Hämeenkatu street, at its eastern end it meets Kalevan puistokatu, branching into Teiskontie and Sammonkatu. Today, the only crossroads on Itsenäisyydenkatu with cross-street vehicle traffic is Tammelan puistokatu–Yliopistonkatu.
Itsenäisyydenkatu was known from the end of the 19th century until the 1950s as the Puolimatkankatu according to the croft named Puolimatka (literally "half way") located in the area. The impetus for renaming the street was the call made by the state to the cities in 1957 to name a significant street Itsenäisyydenkatu in honor of the 40th anniversary of Finland's independence. The name change took effect in 1958.
In 2017, the renovation of the street and the station tunnel began, where the cross-section of the street will be renewed for a tramway to be built in Tampere. The former bus lanes were reserved for the local light rail network so that it runs west of the intersection of Tammelan puistokatu at the south side of the street and east of the intersection in the middle of the street; due to the arrangement, the southern surface of the station tunnel had to be lowered. A bike path was built on the northern edge of the street, and all the aged piping under the street was renewed. The renovation was completed in 2019, and tram traffic will begin in 2021.

https://en.wikipedia.org/wiki/Pestov%E2%80%93Ionin%20theorem | The Pestov–Ionin theorem in the differential geometry of plane curves states that every simple closed curve of curvature at most one encloses a unit disk.
History and generalizations
Although a version of this was published for convex curves by Wilhelm Blaschke in 1916, it is named for and , who published a version of this theorem in 1959 for non-convex doubly differentiable () curves, the curves for which the curvature is well-defined at every point. The theorem has been generalized further, to curves of bounded average curvature (singly differentiable, and satisfying a Lipschitz condition on the derivative), and to curves of bounded convex curvature (each point of the curve touches a unit disk that, within some small neighborhood of the point, remains interior to the curve).
Applications
The theorem has been applied in algorithms for motion planning. In particular it has been used for finding Dubins paths, shortest routes for vehicles that can move only in a forwards direction and that can turn left or right with a bounded turning radius. It has also been used for planning the motion of the cutter in a milling machine for pocket machining, and in reconstructing curves from scattered data points.

https://en.wikipedia.org/wiki/Statistics%20National%20Institute%20%28Venezuela%29 | The Instituto Nacional de Estadística (INE, Statistics National Institute) is the main public statistical body of the Venezuelan Government, being the central entity of the National Statistical System and is in charge of the systematization and publication of statistical data in the Venezuelan territory.
History
The General Directorate of Statistics was created in 1871 as part of the Ministry of Development. The aim was to collect important agricultural and economic information for the country. In 1873, the First National Population Census was carried out, which produced a total population of 1,783,993 inhabitants; in 1881 the second was carried out and in 1991 the third. Thus, one of the Directorate's most significant accomplishments was the conduct of general population censuses with some regularity in the country. Venezuela has carried out 14 censuses from the first one carried out in the year 1873 to 2011.
After 1936, and especially with the enactment of the National Statistics and Census Law of 1944, the National Government showed renewed interest in statistics. The 1944 Law reinforced the obligation of all residents of the country (nationals and foreigners), of all public and private organizations, and of all public officials, to submit the data required of them (according to the technical specifications that are required of them), indicated to collaborate with the National Executive, when requested, in the development of operations.
For 1978, the Central Office of Statistics and Informatics was created, also attached to the Ministry of Development. A few months before the approval of the Statistical Public Function Law (November 2001), officially the institution acquired the name of the Statistics National Institute. By July 2001, it was attached to the Ministry of People's Power of the Office of the Presidency and Monitoring of Government Management and is currently attached to the Ministry of People's Power for Planning.

https://en.wikipedia.org/wiki/Gamma%20ray%20cross%20section | Gamma ray cross section - a measure of the probability that gamma ray interacts with matter. The total cross section of gamma ray interactions is composed of several independent processes: photoelectric effect, Compton scattering, electron-positron pair production in the nucleus field and electron-positron pair production in the electron field (triplet production). The cross section for single process listed above is a part of the total gamma ray cross section.
Other effects, like the photonuclear absorption, Thomson or Rayleigh (coherent) scattering can be omitted because of their nonsignificant contribution in the gamma ray range of energies.
The detailed equations for cross sections (barn/atom) of all mentioned effects connected with gamma ray interaction with matter are listed below.
Photoelectric effect cross section
This phenomenon describes the situation in which a gamma photon interacts with an electron located in the atomic structure. This results the ejection of that electron from the atom. The photoelectric effect is the dominant energy transfer mechanism for X-ray and gamma ray photons with energies below 50 keV, but it is much less important at higher energies, but still need to be taken into consideration.
Usually, the cross section of the photoeffect can be approximated by the simplified equation of
where k = Eγ / Ee, and where Eγ = hν is the photon energy given in eV and Ee = me c2 ≈ 5,11∙105 eV is the electron rest mass energy, Z is an atomic number of the absorber’s element, α = e2/(ħc) ≈ 1/137 is the fine structure constant, and re2 = e4/Ee2 ≈ 0.07941 b is the square of the classical electron radius.
For higher precision, however, the Sauter equation is more appropriate:
where
and EB is a binding energy of electron, and ϕ0 is a Thomson cross section (ϕ0 = 8πe4/(3Ee2) ≈ 0.66526 barn).
For higher energies (>0.5 MeV) the cross section of the photoelectric effect is very small because other effects (especially Compton scattering) dominates. However, for precise calculations of the photoeffect cross section in high energy range, the Sauter equation shall be substituted by the Pratt-Scofield equation
where all input parameters are presented in the Table below.
Compton scattering cross section
Compton scattering (or Compton effect) is an interaction in which an incident gamma photon interact with an atomic electron to cause its ejection and scatter of the original photon with lower energy. The probability of Compton scattering decreases with increasing photon energy. Compton scattering is thought to be the principal absorption mechanism for gamma rays in the intermediate energy range 100 keV to 10 MeV.
The cross section of the Compton effect is described by the Klein-Nishina equation:
for energies higher than 100 keV (k>0.2). For lower energies, however, this equation shall be substituted by:
which is proportional to the absorber’s atomic number, Z.
