https://en.wikipedia.org/wiki/Geometry%20and%20the%20Imagination | Geometry and the Imagination is the English translation of the 1932 book by David Hilbert and Stefan Cohn-Vossen.
The book was based on a series of lectures Hilbert made in the winter of 1920–21. The book is an attempt to present some then-current mathematical thought to "contribute to a more just appreciation of mathematics by a wider range of people than just the specialists." It differentiates between two tendencies in mathematics and any other scientific research: on the one hand, toward abstraction and logical relations, correlating the subject matter in a systematic and orderly manner, and on the other hand an intuitive approach, which moves toward a more immediate grasp of and a "live rapport" with the same material. Further he asserts that intuitive understanding actually plays a major role for the researcher as well as anyone who wishes to study and appreciate Geometry.
Contents
Topics covered by the chapters in the book include the Leibniz formula for , configurations of points and lines with equally many points on each line and equally many lines through each point,
curvature and non-Euclidean geometry, mechanical linkages, the classification of manifolds by their Euler characteristic, and the four color theorem.
Response
The Mathematical Association of America said about the book, "this book is a masterpiece — a delightful classic that should never go out of print". Physics Today called it "a readable exposition of modern geometry and its relation to other branches of mathematics". The Scientific Monthly said about it "has been a classic for twenty years . . . Although it deals with elementary topics, it reaches the fringe of our knowledge in many directions".

https://en.wikipedia.org/wiki/Diminished%20rhombic%20dodecahedron | In geometry, a diminished rhombic dodecahedron is a rhombic dodecahedron with one or more vertices removed. This article describes diminishing one 4-valence vertex. This diminishment creates one new square face while 4 rhombic faces are reduced to triangles. It has 13 vertices, 24 edges, and 13 faces. It has C4v symmetry, order 8.
Like the rhombic dodecahedron, the long diagonal of each rhombic face is times the length of the short diagonal, so that the acute angles on each face measure arccos(), or approximately 70.53°.
Self-dual
Like the dihedral symmetry pyramids, and elongated pyramids, it is self-dual, with the dual geometry inverted across the axis of symmetry. It is one of three self-dual tridecahedra with C4v symmetry.
Space-filling
This polyhedron along with the cube is space-filling, like the rhombic dodecahedral honeycomb. Six diminished points come together to form cubic holes.
Cartesian coordinate
It has 13 of 14 Cartesian coordinates of the rhombic dodecahedron are:
8: (±1, ±1, ±1)
1: (2, 0, 0)
2: (0, ±2, 0)
2: (0, 0, ±2)
Augmented cuboctahedron
The same topological polyhedron with different proportions can be constructed as an augmented cuboctahedron, with a square face augmented by a square pyramid. This construction requires merging of neighboring coparallel triangular faces into new 60° rhombic faces. This can also be seen as an asymmetric stellation of a cuboctahedron. It retains 5 square faces, and 4 equilateral triangle faces of the cuboctahedron.
The 13 Cartesian coordinate can be positioned as:
1: ( 2, 0, 0)
4: (±1, ±1, 0)
4: (±1, 0, ±1)
4: ( 0, ±1, ±1)
Augmenting two opposite squares will create a dihedral rhombic dodecahedron, doubling the symmetry to D4h symmetry, order 16. Augmenting pyramids on all six square faces, with merged faces will produce a regular octahedron, restoring full octahedral symmetry, order 48.

https://en.wikipedia.org/wiki/Locally%20nilpotent%20derivation | In mathematics, a derivation of a commutative ring is called a locally nilpotent derivation (LND) if every element of is annihilated by some power of .
One motivation for the study of locally nilpotent derivations comes from the fact that some of the counterexamples to Hilbert's 14th problem are obtained as the kernels of a derivation on a polynomial ring.
Over a field of characteristic zero, to give a locally nilpotent derivation on the integral domain , finitely generated over the field, is equivalent to giving an action of the additive group to the affine variety . Roughly speaking, an affine variety admitting "plenty" of actions of the additive group is considered similar to an affine space.
Definition
Let be a ring. Recall that a derivation of is a map satisfying the Leibniz rule for any . If is an algebra over a field , we additionally require to be -linear, so .
A derivation is called a locally nilpotent derivation (LND) if for every , there exists a positive integer such that .
If is graded, we say that a locally nilpotent derivation is homogeneous (of degree ) if for every .
The set of locally nilpotent derivations of a ring is denoted by . Note that this set has no obvious structure: it is neither closed under addition (e.g. if , then but , so ) nor under multiplication by elements of (e.g. , but ). However, if then implies and if , then .
Relation to -actions
Let be an algebra over a field of characteristic zero (e.g. ). Then there is a one-to-one correspondence between the locally nilpotent -derivations on and the actions of the additive group of on the affine variety , as follows.
A -action on corresponds to an -algebra homomorphism . Any such determines a locally nilpotent derivation of by taking its derivative at zero, namely where denotes the evaluation at .
Conversely, any locally nilpotent derivation determines a homomorphism by
It is easy to see that the conjugate actions correspond to conjugate derivations, i.e. if and then and
The kernel algorithm
The algebra consists of the invariants of the corresponding -action. It is algebraically and factorially closed in . A special case of Hilbert's 14th problem asks whether is finitely generated, or, if , whether the quotient is affine. By Zariski's finiteness theorem, it is true if . On the other hand, this question is highly nontrivial even for , . For the answer, in general, is negative. The case is open.
However, in practice it often happens that is known to be finitely generated: notably, by the Maurer–Weitzenböck theorem, it is the case for linear LND's of the polynomial algebra over a field of characteristic zero (by linear we mean homogeneous of degree zero with respect to the standard grading).
Assume is finitely generated. If is a finitely generated algebra over a field of characteristic zero, then can be computed using van den Essen's algorithm, as follows. Choose a local slice, i.e. an element and put . |
https://en.wikipedia.org/wiki/Maddison%20Project | The Maddison Project, also known as the Maddison Historical Statistics Project, is a project to collate historical economic statistics, such as GDP, GDP per capita, and labor productivity.
It was launched in March 2010 to continue the work of the late economic historian Angus Maddison. The project is under the Groningen Growth and Development Centre at the University of Groningen, which also hosts the Penn World Table, another economic statistics project.
Reception
Development economist Branko Milanović (writing for the World Bank), development economist Morten Jerven, and billionaire philanthropist Bill Gates have identified the Maddison Project, the Penn World Tables, and World Bank/IMF data (the World Development Indicators), as the three main sources of worldwide economic statistics such as GDP data, with the focus of the Maddison Project being on historical data. Economist Paul Krugman has suggested the Maddison Project as a data source for historical debt, growth, and labor output and productivity data.
Our World In Data, a website with data-driven discussion of a number of topics related to long-run economic and human development, uses the Maddison Project as one of its data sources.

https://en.wikipedia.org/wiki/Torus%20fusion | Torus fusion (tofu) is a proprietary computer network topology for supercomputers developed by Fujitsu. It is a variant of the torus interconnect. The system has been used in the K computer and the Fugaku supercomputer (and their derivatives).
Tofu has a six-dimensional mesh/torus topology, a scalability of over 100,000 nodes, and full-duplex links that have a peak bandwidth of 10 GB/s (5 GB/s per direction). Each node is connected to its own InterConnect Controller (ICC) chip, which contains four Tofu interfaces (one for the node and three for connecting to other ICC chips) and a router.
Software support
Tofu's six-dimensional mesh/torus topology is abstracted by software to appear as a three-dimensional torus; it is supported by a Tofu-optimized version of the open-source Open MPI Message Passing Interface library. Users can create application programs adapted to either a one-, two-, or three-dimensional torus network.

https://en.wikipedia.org/wiki/Wells%20effect | The Wells effect describes an empirical disconnect between people's judgment of guilt in a trial setting, and both the mathematical and subjective probability involving guilt. This finding shows that evidence that makes a defendant's guilt more or less probable will not necessarily make a guilty verdict more or less likely, which suggests that the judgments made in courts are not governed by rational decision making.
Origins
This behavioral effect was first established in a series of experiments by psychologist Gary L. Wells. This study examined the difference between how mock jurors judged naked statistics (statistical evidence that is unrelated to the specific case) and other forms of evidence, and found that a simple probability-threshold model (i.e., that jurors decide guilt when the subjective probability of guilt crosses a threshold value) cannot account for juror behavior.
The experiments were based on variants of the hypothetical Blue Bus Case, which first appeared in the legal literature to describe the unsuitability of naked statistics in trial. In Wells's studies, participants were asked to rule on a case in which a woman had watched her dog get struck by a bus and killed, but was unable to identify the bus. One group of participants (in the rate of traffic case) was presented with evidence that the Blue Bus Company was responsible for 80% of the traffic on the road, and the competing Gray Bus Company was responsible for the other 20%; a second group (in the weight attendant case) was presented with the testimony of a weight attendant who made a record indicating that a Blue Bus was on the road at a time corresponding to the accident, and that of a second witness who testified that this record was known to be incorrect 20% of the time. When asked to guess the probability that the Blue Bus Company was responsible for the accident, participants from both groups correctly reported an average 80% chance. However, when asked to make a determination of guilt in the case, those in the first group made a judgment against the Blue Bus Company only 8.2% of the time, while those in the second group found the Blue Bus Company liable in 67.1% of the cases.
Variants and proposed mechanisms
The original study found evidence for a process Wells described as "fact-to-evidence reasoning". A juror engaged in such reasoning would ignore evidence unless the evidence itself can (or cannot) be supported by the judgment of the ultimate fact. I.e., jurors would ignore naked statistics (such as the rate of traffic) because the identity of the responsible bus wouldn't prove or disprove the statistics, but jurors would consider the weight attendant's testimony because his testimony could be supported (or not) by the identity of the responsible bus. In two additional experiments, participants were presented with the tire tracks case or the tire tracks-belief case. Both cases relied on the testimony of a transportation official who examined the prints of tir |
https://en.wikipedia.org/wiki/Softwall | softwall is a flexible room divider designed by Stephanie Forsythe and Todd MacAllen of molo. Made from paper or nonwoven polyethylene, the walls use a structured honeycomb geometry to bend, curve, expand and contract. The honeycomb structure also provides acoustic absorption. Part of a modular system, each softwall can connect to another by magnetic end panels. The walls have been used to create booths for trade fairs, pop-up retail, sculptural art installations, backdrops for performances, as well as to divide space in living and working environments.
In 2003, softwall was welcomed into the Museum of Modern Art’s permanent collection. Two years later, it was presented with the INDEX Award for Design to Improve Life.
Design
Forsythe and MacAllen first conceived softwall as a method for repurposing architectural shells to provide shelter for the homeless. The concept grew into a modular system of space partitions that could quickly and easily transform space to suit diverse uses, whether in small live/work studios or large scale environments.
softwall reflects molo’s interest in sustainable building methods and flexible living. Both the paper and polyethylene textile used for the soft collection are 100% recyclable. These materials are paired with non-toxic fire retardants, adhesives, and inks. By organizing the paper or textile layers with a honeycomb structure, the material takes on strength to create freestanding partitions and the flexibility to adapt to or shape space. The pleated surface and interior cells, which facilitate movement, also absorb sound.

https://en.wikipedia.org/wiki/Hel%20Braun | Helene (Hel) Braun (June 3, 1914 – May 15, 1986) was a German mathematician who specialized in number theory and modular forms. Her autobiography, The Beginning of A Scientific Career, described her experience as a female scientist working in a male-dominated field at the time, in the Third Reich.
She is known for proving the convergence of the Eisenstein series.
Scientific career
Braun studied mathematics at the University of Marburg from 1933 to 1937. In 1937 she worked with Carl Ludwig Siegel in Frankfurt to study the decomposition of quadratic forms into sums of squares. Her dissertation, Über die Zerlegung quadratischer Formen in Quadrate, was also supervised by Georg Aumann. After completing that work, he took her on as a scientific assistant before she became a professor in her own right teaching the theory of Hermitian forms in 1940.
She became a lecturer at the University of Göttingen in 1941, becoming a full professor in 1947. From 1947 through 1948, she was a member of the Institute for Advanced Study.
In 1951, Braun moved and became a professor at the University of Hamburg where she supervised many doctoral students including Eberhard Becker, Manfred Knebusch and Karl Mathiak and while there worked with Emil Artin and other internationally acclaimed mathematicians.
Personal life
Braun never married, but in the 1960s while she was a professor at the University of Hamburg, she shared an apartment with Emil Artin, and their relationship was equivalent to marriage according to everyone who knew them.
After she retired in 1981, she lived out the rest of her life in Hamburg.
Selected publications
A list of the publications by Hel Braun was published by Helmut Strade in the Communications of the Mathematical Society in Hamburg, Volume XI, Issue 4, 1987.
She wrote two books:

https://en.wikipedia.org/wiki/Howson%20property | In the mathematical subject of group theory, the Howson property, also known as the finitely generated intersection property (FGIP), is the property of a group saying that the intersection of any two finitely generated subgroups of this group is again finitely generated. The property is named after Albert G. Howson who in a 1954 paper established that free groups have this property.
Formal definition
A group is said to have the Howson property if for every finitely generated subgroups of their intersection is again a finitely generated subgroup of .
Examples and non-examples
Every finite group has the Howson property.
The group does not have the Howson property. Specifically, if is the generator of the factor of , then for and , one has . Therefore, is not finitely generated.
If is a compact surface then the fundamental group of has the Howson property.
A free-by-(infinite cyclic group) , where , never has the Howson property.
In view of the recent proof of the Virtually Haken conjecture and the Virtually fibered conjecture for 3-manifolds, previously established results imply that if M is a closed hyperbolic 3-manifold then does not have the Howson property.
Among 3-manifold groups, there are many examples that do and do not have the Howson property. 3-manifold groups with the Howson property include fundamental groups of hyperbolic 3-manifolds of infinite volume, 3-manifold groups based on Sol and Nil geometries, as well as 3-manifold groups obtained by some connected sum and JSJ decomposition constructions.
For every the Baumslag–Solitar group has the Howson property.
If G is group where every finitely generated subgroup is Noetherian then G has the Howson property. In particular, all abelian groups and all nilpotent groups have the Howson property.
Every polycyclic-by-finite group has the Howson property.
If are groups with the Howson property then their free product also has the Howson property. More generally, the Howson property is preserved under taking amalgamated free products and HNN-extension of groups with the Howson property over finite subgroups.
In general, the Howson property is rather sensitive to amalgamated products and HNN extensions over infinite subgroups. In particular, for free groups and an infinite cyclic group , the amalgamated free product has the Howson property if and only if is a maximal cyclic subgroup in both and .
A right-angled Artin group has the Howson property if and only if every connected component of is a complete graph.
Limit groups have the Howson property.
It is not known whether has the Howson property.
For the group contains a subgroup isomorphic to and does not have the Howson property.
Many small cancellation groups and Coxeter groups, satisfying the ``perimeter reduction" condition on their presentation, are locally quasiconvex word-hyperbolic groups and therefore have the Howson property.

Examples of softseating are held in the Museum of Modern Art, the Art Institute of Chicago and the Cooper Hewitt, Smithsonian Design Museum.
Design
The paper or textile materials take on flexibility and strength through an ordered, honeycomb geometry. Depending on the number of layers, the honeycomb creates stools and benches of various sizes. When folded, the furniture can be stored like a book. Magnetic panels set into the final layers of each element allow softseating to connect to itself or to link with other elements to form long benches or creative seating arrangements. Stephanie Forsythe and Todd MacAllen developed the design after considering methods of maximizing small urban spaces for living and working, and how to transform such spaces to suit many types of use.

https://en.wikipedia.org/wiki/Bayesian%20epistemology | Bayesian epistemology is a formal approach to various topics in epistemology that has its roots in Thomas Bayes' work in the field of probability theory. One advantage of its formal method in contrast to traditional epistemology is that its concepts and theorems can be defined with a high degree of precision. It is based on the idea that beliefs can be interpreted as subjective probabilities. As such, they are subject to the laws of probability theory, which act as the norms of rationality. These norms can be divided into static constraints, governing the rationality of beliefs at any moment, and dynamic constraints, governing how rational agents should change their beliefs upon receiving new evidence. The most characteristic Bayesian expression of these principles is found in the form of Dutch books, which illustrate irrationality in agents through a series of bets that lead to a loss for the agent no matter which of the probabilistic events occurs. Bayesians have applied these fundamental principles to various epistemological topics but Bayesianism does not cover all topics of traditional epistemology. The problem of confirmation in the philosophy of science, for example, can be approached through the Bayesian principle of conditionalization by holding that a piece of evidence confirms a theory if it raises the likelihood that this theory is true. Various proposals have been made to define the concept of coherence in terms of probability, usually in the sense that two propositions cohere if the probability of their conjunction is higher than if they were neutrally related to each other. The Bayesian approach has also been fruitful in the field of social epistemology, for example, concerning the problem of testimony or the problem of group belief. Bayesianism still faces various theoretical objections that have not been fully solved.
Relation to traditional epistemology
Traditional epistemology and Bayesian epistemology are both forms of epistemology, but they differ in various respects, for example, concerning their methodology, their interpretation of belief, the role justification or confirmation plays in them and some of their research interests. Traditional epistemology focuses on topics such as the analysis of the nature of knowledge, usually in terms of justified true beliefs, the sources of knowledge, like perception or testimony, the structure of a body of knowledge, for example in the form of foundationalism or coherentism, and the problem of philosophical skepticism or the question of whether knowledge is possible at all. These inquiries are usually based on epistemic intuitions and regard beliefs as either present or absent. Bayesian epistemology, on the other hand, works by formalizing concepts and problems, which are often vague in the traditional approach. It thereby focuses more on mathematical intuitions and promises a higher degree of precision. It sees belief as a continuous phenomenon that comes in various degrees, so-calle |

https://en.wikipedia.org/wiki/Hypercalculia | Hypercalculia is "a specific developmental condition in which the ability to perform mathematical calculations is significantly superior to general learning ability and to school attainment in maths." A 2002 neuroimaging study of a child with hypercalculia suggested greater brain volume in the right temporal lobe. Serial SPECT scans revealed hyperperfusion over right parietal areas during performance of arithmetic tasks.
Math and reading achievement profiles in autistic individuals
Children at any age may be stronger in language or in mathematics, but very rarely in both. Autistic children are no different. A rare example of a child with multiple savant tendencies is a case study of a thirteen year old girl. Pacheva, Panoy, Gillberg, and Neville discovered this young woman has not only hypercalculia abilities, but also showcases hyperlexia, and hypermnesia capabilities.
A study published in 2014 examined the reading and math achievement profiles and their changes over time within a sample of children between the ages 6–9 diagnosed with an autism spectrum disorder. What they found was that there are four distinct achievement profiles: higher-achieving (39%), hyperlexia (9%), hypercalculia (20%) and lower-achieving (32%). A previous study conducted in 2009 estimated the rate of hypercalculia at 16.2% in ASD adolescents.
According to Wei, Christiano, Yu, Wagner, and Spiker, research of the ASD achievement profile, hypercalculia, is sometimes overlooked in academic settings. Sometimes this oversight is a result of more resources being spent on understanding the capabilities of children who exhibit hyperlexia. Children with an ASD have shown various results during testing for hypercalulia. Some of these varied results indicate: below average performance of mathematical and problem solving tasks, average proficiency, and high-achievers topping the 99th percentile on 'standardized math achievement measures.'
There is an ongoing debate concerning the cause of hypercalculia along with other savant perceptions. Some researchers theorize that obsessive tendencies may trigger greater attention to certain areas of their lives.
Individuals with autism will sometimes focus a lot of their time, energy, and attention on schedules or routines, calendar calculations, numbers or counting, and/or music.
Other researchers speculate that people with savant tendencies may use different brain areas while they are processing subjects of their higher abilities. Among other debate arguments are hypotheses with regards to neural processes and working memory storage capabilities.
Wallace sometimes refers to these individuals as "mathematical savants" or "arithmetic savants." In his experience, individuals with this ability tend to prefer a chunking or segmentation method of sorts. Their proclivities tend to push them towards breaking bigger things down to smaller things like numbers or equations. This data led Wallace to research, "prime number savants." Prime number s |

https://en.wikipedia.org/wiki/Boolean%20differential%20calculus | Boolean differential calculus (BDC) (German: (BDK)) is a subject field of Boolean algebra discussing changes of Boolean variables and Boolean functions.
Boolean differential calculus concepts are analogous to those of classical differential calculus, notably studying the changes in functions and variables with respect to another/others.
The Boolean differential calculus allows various aspects of dynamical systems theory such as
automata theory on finite automata
Petri net theory
supervisory control theory (SCT)
to be discussed in a united and closed form, with their individual advantages combined.
History and applications
Originally inspired by the design and testing of switching circuits and the utilization of error-correcting codes in electrical engineering, the roots for the development of what later would evolve into the Boolean differential calculus were initiated by works of Irving S. Reed, David E. Muller, David A. Huffman, Sheldon B. Akers Jr. and (, ) between 1954 and 1959, and of Frederick F. Sellers Jr., Mu-Yue Hsiao and Leroy W. Bearnson in 1968.
Since then, significant advances were accomplished in both, the theory and in the application of the BDC in switching circuit design and logic synthesis.
Works of , Marc Davio and in the 1970s formed the basics of BDC on which , and further developed BDC into a self-contained mathematical theory later on.
A complementary theory of Boolean integral calculus (German: ) has been developed as well.
BDC has also found uses in discrete event dynamic systems (DEDS) in digital network communication protocols.
Meanwhile, BDC has seen extensions to multi-valued variables and functions as well as to lattices of Boolean functions.
Overview
Boolean differential operators play a significant role in BDC. They allow the application of differentials as known from classical analysis to be extended to logical functions.
The differentials of a Boolean variable models the relation:
There are no constraints in regard to the nature, the causes and consequences of a change.
The differentials are binary. They can be used just like common binary variables.

https://en.wikipedia.org/wiki/The%20Saga%20Continues%20%28Wu-Tang%20Clan%20album%29 | The Saga Continues is a compilation album by American rap ensemble Wu-Tang Clan, produced by long-time producer Mathematics released on October 13, 2017 on eOne. The group name was shortened to "Wu-Tang" to mark the fact that the album features all Wu-Tang Clan members except U-God due to his legal issues with the group over royalties. It also features guest appearances from Streetlife, Redman, Sean Price and others. Producer Mathematics has explained, "It's a Wu-Tang record of course, [but] it can't be a complete Wu-Tang Clan album without [U-God]."
The Saga Continues was promoted with two singles, "People Say" and "Lesson Learn'd", both featuring Redman. The album debuted on at number 15 on Billboard 200 chart and at number one on Independent Albums having sold 19,461 copies in the first week, and including streams it was 24,613 copies.
Background
After releasing A Better Tomorrow, the group continued to work on their solo albums: Ghostface Killah released his sequel to Twelve Reasons to Die and collaboration album Sour Soul with BadBadNotGood, Method Man released The Meth Lab, Inspectah Deck put out two albums with his side group Czarface. Masta Killa kept on working his fourth album entitled Loyalty Is Royalty which eventually was released on September 29, 2017.
Meanwhile, Wu-Tang Clan's most controversial album, Once Upon a Time in Shaolin, was sold to Martin Shkreli for $2,000,000.
On August 25, 2017, without any announcement, a track called "People Say" was released stating that it was a new single off Wu-Tang Clan's upcoming album. A few days later, RZA announced that the new project would be entitled The Saga Continues and would be entirely "crafted by" Wu-Tang Clan DJ, Mathematics. In the later interview he commented:
On September 22, 2017, the second single, "Lesson Learn'd", was released, and on October 4, a video for "People Say" was published on Wu-Tang Clan Vevo YouTube account.
Critical reception
Upon its release, The Saga Continues received mixed to positive reviews from most music critics. At Metacritic, which assigns a normalized rating out of 100 to reviews from mainstream critics, the album received an average score of 64, based on 16 reviews, which indicates "generally favorable reviews". AllMusic's reviewer, who gave the album 3 out of 5 stars, stated that "Mathematics fills The Saga Continues with dark, moody beats, atmospheric keyboard patches, snatches of classic soul sides, and samples from vintage kung-fu movies. If this isn't quite a brother to Enter the Wu-Tang (36 Chambers)". Alex McLevy of The A.V. Club rated the album a "B−" calling it more "cobbled-together" than A Better Tomorrow, but also stated that "it turns out to be the best Wu-related effort since 2010’s thin yet enjoyable Wu-Massacre". He also praised Mathematics' production saying that he "has been intricately involved with the Wu since its inception […] and he turns out to do a better RZA than the RZA these days, stitching together more than a |

https://en.wikipedia.org/wiki/Blohm%20%26%20Voss%20P.202 | The Blohm & Voss P.202 was an unusual design study for a variable-geometry jet fighter during World War II. It was the first design to incorporate a slewed wing (also known as an oblique or scissor wing) in which one side swept forward and the other back. The P.202 was never built or flown.
Design
The high speeds attainable by jet aeroplanes led German workers to develop the swept wing, in order to minimise the problems met as the speed of sound was approached. But sweeping the wings causes problems of its own, especially at the low speeds used for takeoff and landing. A variable-sweep mechanism was one possible solution but it would be complex, heavy and expensive. It also has problems with movement of the centre of lift. Both backwards and forwards sweep were investigated and they proved to have opposite disadvantages. Sweeping one wing forwards and the other back would balance out the aerodynamic problems and a one-piece slewed wing approach would not need such a complex sweep mechanism.
The P.202 jet fighter project emerged as Blohm & Voss designer Richard Vogt's ingenious solution. Conventional in other respects, the high-mounted wing could be slewed by up to 35° for high-speed flight. The wing span was when unswept and when fully swept.
The long main undercarriage retracted into the wing, while a nose wheel completed the tricycle undercarriage.
The P.202 was powered by a pair of BMW 003 turbojets, slung underneath the fuselage centre section and exhausting behind the wing.
Provision for three forward-firing cannon was made in the nose.

https://en.wikipedia.org/wiki/Video%20games%20in%20Turkey | Video games in Turkey is a massive industry with many branches of it and also covers pastime in Turkey that includes the production, sale, import/export, and playing of video games.
Market statistics
In 2021, the market statistics in total reached 1.2B$, around 600M$ coming from mobile games. Turkey’s market statistics were $464 million in 2015, while in 2016 it was $755 million and most of the revenue in 2016 was $332.5 million in mobile games, the rest was obtained from the computer and console genre. Turkey grew 7.2% compared with the previous year, in online game revenue during 2016, Turkey ranked 16th in the world in both the mobile PC and console area. Today in general & with all genres, Turkey stands at 18th globally. The global rank within all genres has not seen a change.
Many big Turkish developer companies exist, such as Peak in the mobile games genre, Tale Worlds in the PC genre for many years. (e.g Mount & Blade.)
Professional gaming
Turkey has a presence in the professional e-sports market, especially in League of Legends and other games created by Riot Games.
E-Sport team found that the market for more than ten professionals from more than four thousand in Turkey are also licensed e-athletes. Beşiktaş and traditional sports clubs also stepped in, and other sports clubs, especially Galatasaray and Fenerbahçe, joined the e-Sports market.
The Türkiye Digital Games Federation was established in 2011 and later superseded by the e-Sports Federation of Turkey on April 24, 2018.
Rating System
In Turkey, the most widely used video game content rating system PEGI (Pan European Gaming Information), does not have a legal basis that supports it officially but it was semi-officially introduced to the country in 2014-2015 and is used in both foreign and Turkish published video games all around the country, and in almost all cases, though Turkey is not officially represented in the PEGI council. Other labels can be seen as well such as the German USK specially on second-hand items.
In 2006, the Intellectual Property Registration and Registration Department made arrangements about a regulation "Computer Games", a new regulation for using & regarding marking content ratings system that was and has been implemented for film, television and video games in the Turkish market that are sold. -Although the criteria used for marking are still officially and legally somewhat uncertain, but for video games is dominated by PEGI, this method is mostly applied to products sold physically, there is no control mechanism for video games acquired through digital distribution etc.
With the Regulation on Internet Bulk Use Providers, which came into force in 2009, made the play of video games (or the screening of films) that include drug or stimulant habit, suicidal orientation, sexual abuse, obscenity, prostitution, violence, gambling etc. like-elements prohibited at public workplaces, though not applying to certain private workplaces.

https://en.wikipedia.org/wiki/VFL/AFL%20premiership%20and%20grand%20final%20statistics | This page is a collection of VFL/AFL premiership and grand final statistics. The Australian Football League (AFL), known as the Victorian Football League (VFL) until 1990, is the elite national competition in men's Australian rules football. Each year, the premiership is awarded to the club that wins the AFL Grand Final. The grand final has been played in all VFL/AFL seasons except for 1897 and 1924 (where the premiership was awarded without a grand final being played), and has been an annual tradition in its current format since 1931.
Since the introduction by the League of equalisation policies of a salary cap and draft in 1987, every team currently competing in the Australian Football League (except for , which has not yet qualified for a finals series as of 2023) has qualified for a grand final. This has had a significant impact on the spread of premierships: since 1990, fourteen clubs have won a premiership, compared with only five clubs between 1967 and 1989. Of the teams currently competing in the Australian Football League, only , Gold Coast and are yet to win a premiership.
As of 2023, Collingwood, Essendon and Carlton are all tied for winning 16 premierships, with Collingwood winning the most consecutive premierships, at four between 1927 and 1930.

Syrian Civil War
Ma'adan was captured by rebel forces in the Raqqa campaign (2012–13) during the Syrian Civil War. ISIL, which had participated in the fighting against Syrian government forces in the Raqqa governate, wrested control of the region, including Ma'adan, from other rebel forces in January 2014. Three and a half years later, though the town was still under ISIL control, ISIL's position in the Syrian Civil War had deteriorated significantly such that it was in danger of losing the entire governate of Raqqa. Ma'adan became an important stronghold used by the organisation during the Central Syria campaign (2017). Syrian government forces encountered significant resistance at Ma'adan when they attempted to advance on the town in mid-August, and consequently bypassed the town in their approach to Deir ez Zor. However, on 24 August ISIL forces launched a large-scale operation west of Ma'adan alongside the western bank of the Euphrates, capturing seven villages from the Syrian Army and allied tribal fighters. Overall, government forces were pushed back 30 kilometers from the western outskirts of Ma'adan. Nearly a month later, on 23 September 2017, Ma'adan was liberated by the Syrian government's Tiger Forces during their offensive from the south east. This removed the last of ISIL's territory on the west bank of the Euphrates, north of Deir ez-Zor

https://en.wikipedia.org/wiki/Minnesota%20Office%20of%20Higher%20Education | The Minnesota Office of Higher Education is an executive branch agency that is responsible for the coordination of higher education information, financial aid programs, statistics, and policy in the U.S. state of Minnesota. The agency does not run or administer the two public systems of higher education in Minnesota, the Minnesota State Colleges and Universities system or the University of Minnesota system.
Functions
In contrast to many other states, the Minnesota Office of Higher Education primarily functions as a policy and coordination role between the state's public, private non-profit and for-profit colleges and universities. It is the designated state higher education executive office or SHEEO organization. The agency also participates with the National Council for State Authorization Reciprocity or NC-SARA.
It also administers financial aid on behalf of the state with respect to state and federal student loans and aid. It also provides general counseling on student loans and finances to the public. Annually it administers up to $150 million of state grants and the state loan program called SELF to students attending schools in Minnesota.
The agency also provides research on higher education spending for the state legislature and advises the Minnesota Department of Veterans Affairs on the administration of the state and federal G.I. Bill. In addition to these functions it also licenses higher education programs in Minnesota.
Initiatives
The agency has set a statewide policy goal of increasing the percent of Minnesota citizens to that have attained a collegiate certificate or degree to 70 percent by 2025. It is also working to research ways of reducing structural barriers and achievement gaps for students of color, persons of low income, persons with disabilities and other groups. In 2013, the state legislature passed the Minnesota Dream Act which allowed for undocumented students to be eligible for in-state tuition. The agency administers the funding and determines eligibility for the dream act and for Deferred Action for Childhood Arrival students.

https://en.wikipedia.org/wiki/Enrico%20D%27Ovidio | Enrico D'Ovidio (1842-1933) was an Italian mathematician who is known by his works on geometry.
Life and work
D'Ovidio, son of a liberal parents involved in the Italian independence movement, studied at the university of Naples under his uncle, Achille Sannia, who prepared him to enter in the School of Bridges and Roads. In 1869, he published with Sannia a very successful textbook to teach geometry in the schools.
Encouraged by Eugenio Beltrami, he obtained the chair on Algebra and Analytic Geometry at the university of Turin in 1872, and he remained there for the remaining 46 years of his life. He was also rector of the university from 1880 to 1885.
The research of D'Ovidio was mainly in geometry and the most important works were produced when he was in Turin. Specially interesting is his work Le funzioni metriche fondamentali negli spazi di quante si vogliono dimensioni e di curvatura costante (The fundamental metrical functions in the n-dimensional spaces of constant curvature), published in 1876 and where he stated for first time the law of sines in n-dimensional curved spaces.

Powered exoskeleton
Humanoid robot "The beginning of the development of humanoid robotics coincided with the beginning of the development of the world's first active exoskeletons at the Mihailo Pupin Institute in 1969, under the guidance of Prof. Vukobratović. Legged locomotion systems were developed first. Also, the first theory of these systems was developed in the same institute, in the frame of active exoskeletons. Hence, it can be said that active exoskeletons were the predecessors of the modern high-performance humanoid robots. The present-day active exoskeletons are developed as the systems for enhancing capabilities of the natural human skeletal system. The most successful version of an active exoskeleton for rehabilitation of paraplegics and similar disabled persons, pneumatically powered and electronically programmed was realized and tested at Belgrade Orthopedic Clinic in 1972."
Robot locomotion
Zero moment point "The zero moment point is a very important concept in the motion planning for biped robots. Since they have only two points of contact with the floor and they are supposed to walk, "run" or "jump" (in the motion context), their motion has to be planned concerning the dynamical stability of their whole body.
