Gregorios of Parumala

Gregorios of Parumala (15 June 1848 – 2 November 1902), also known as Parumala Thirumeni (Bishop of Parumala) and Geevarghese Mar Gregorios, was a Metropolitan of the Malankara Church. Parumala Thirumeni became the first person of Indian origin to be canonised as saint. In 1947, the Malankara Orthodox Syrian Church declared Mar Gregorios as a saint, making him the first saint from India canonized by that church. In November 1987, the Syriac Orthodox Church canonized him as a saint.

Early life
Gregorios was born in Pallathetta family in the Chathuruthy house at Mulamthuruthy near Cochin, India on 15 June 1848. His parents were Mathai Gheevarghese and Mariam Gheevarghese. He was called by the name ‘Kochaippora’ and was given the baptismal name ‘Geevarghese’. Geevarghese had two brothers and two sisters; Kurian, Eli, Mariam and Varkey. Geevarghese was the youngest. Geevarghese's mother died when he was a small boy and since then he was under the loving care of his elder sister Mariam.

At a very young age, Geevarghese had shown interest in spiritual matters. His devotion, humility and above all, his ability to sing the traditional Syriac hymns beautifully and perfectly, came to the notice of his uncle Malpan Geevarghese. The uncle wanted to raise his nephew to be a priest and his family members, who knew Geevarghese's character too agreed to the Malpan's request.

Priesthood
Parumala Mor Gregorios was born into a well-known family of Malankara Jacobite Syrian Christians, with a lineage that can be traced back to the brotherhood of Mor Anthrayos, a bishop of the Syriac Orthodox Church in Jerusalem. He was taught by his uncle Geevarghese Malpan and was ordained the 9-year-old Geevarghese, a quroyo (sub-deacon) on the Feast of the Cross (Kanni 14, M.E.1033 / 26 September 1857) at the age of ten by Malankara Metropolitan Mathews Mar Athanasius at St. George Syrian Cathedral, Karingachira. He continued his training with Malpan until the latter died from smallpox. Gregorios was also infected with smallpox but survived. He was ordained as a Mshamshono (Deacon) by Yuyakim Mor Koorilos Reesh-Episcopa of Malankara (Patriarchal Delegate of Malankara) then after one month Priest at the age of 18 in 1865 also Cor-Episcopa (Monk-Archpriest) again by Yuyakim Mor Koorilos Reesh-Episcopa of Malankara (Patriarchal Delegate of Malankara) and as a Ramban (monk-priest) at the age of 22 by Malankara Metropolitan Joseph Mar Dionysios in 1872.

On 10 December 1876, the Ignatius Peter IV Patriarch of Antioch, promoted the 28-year old Gregorios to be a Metropolitan at St. Thomas Jacobite Syrian Church, Vadakkan Paravoor, at which point his official name became Geevarghese Mar Gregorios. He was the youngest of who all were elevated as bishops and was called Kochu Thirumeni (Young Bishop). Gregorios was given the charge of Niranam Diocese.

Metropolitan
In his bishopric, in the Niranam Diocese, Gregorios established various churches and was the motivator to establish schools in different parts of Malankara. In the late 1890s, many educational institutions were started by the Malankara Church under the initiative and guidance of him and Joseph Mar Dionysius. Examples of these include St. Thomas School at Mulanthuruthy, St. Ignatius School at Kunnamkulam, and the Syrian English School (now known as MGM High School) at Thiruvalla.

Following the death of fellow metropolitans (bishops), the administration of Thumpamon and Kollam dioceses also passed to him. In 1887, the first block of the Parumala Seminary was consecrated.

By 1895, Gregorios had made Parumala his main spiritual centre. The church that he founded there in that year was consecrated to Saint Peter and Saint Paul. He would wake at 4 am to pray the Shehimo prayers and he fasted on Wednesday and Fridays, as well as during Lent.

Geevarghese visited Jerusalem in 1895. He visited almost all the important places of Christendom and led the Passion Week services at Syrian Orthodox Church in the Holy City with accompanied members Geevarghese Dionysius of Vattasseril, Kochuparambil Paulose Koorilos and Osthatheos Sleeba (Later Patriarchal Delegate of Malankara) led as guide. On his return, he collected a certain amount from all the Parishes in Malankara and sent a Silver Cross as offering to the Holy church in Jerusalem.

Disciples
Among the many disciples of Gregorios, four deserve special notice

1. Vattasseril Geevarghese (later, Malankara Metropolitan Geevarghese Dionysius of Vattasseril) ( served as the Private Secretary of Mar Gregorios of Parumala)

2. Panampady Paulose (later, Koorilos Paulose).

2. Kuttikattu Paulose (later, Paulose Athanasios)

3. Kallasseril Geevarghese (later, Catholicos of Malankara Church and Malankara Metropolitan Baselios Geevarghese II)

Death
Gregorios had a stomach ulcer and it became chronic in 1902. Treatment proved futile and he grew weaker and weaker. On 2 November 1902, Gregorios left for his heavenly abode. The funeral was conducted at Saint Peter's and Saint Paul's Malankara Orthodox Church, Parumala, on 3 November 1902. Thousands of people and hundreds of priests were present at the funeral who gave testimony of the saintly Gregorios. The mausoleum which Gregorios was interred in has become a popular pilgrimage site.

In Malankara Orthodox Church
On the occasion of 45th death anniversary of Geevarghese Mar Gregorios, based on the decision of the episcopal synod held in 1947, Baselios Geevarghese II, Catholicos of the East and Malankara Metropolitan declared Mar Gregorios as a saint for the Malankara Syrian Church on 2 November 1947.

In Jacobite Syrian Christian Church (Syrian Orthodox)
According to the recommendation of the local synod of Church in India, held on 22 August 1987 Ignatius Zakka I, Patriarch of Antioch, head of Syriac Orthodox Church declared Mar Gregorios as canonized saint for Jacobite Syrian Christian Church on 20 October 1987.

Barry Maranta

Barry Maranta (born 18 December 1934), is an Australian businessman and co-founder of the Brisbane Broncos rugby league team. As well as being a founder of the Broncos he is currently a Sky Shades president. His grandson Lachlan Maranta, became a Brisbane Broncos player.

An Old Boy of Marist College Rosalie in Brisbane and a former first grade cricketer and rugby league footballer, Maranta became a sports consultant and entered into a partnership with Wayne Reid, forming the organisation, International Sports Management. After seeing an interstate Australian Rules Football match that utilised "state of origin" selection rules in 1978, he started trying to convince Queensland Rugby League president Ron McAuliffe to instigate a similar concept in rugby league. This would ultimately have long-ranging effects as the State of Origin series phenomenon took off, becoming one of Australia's biggest sporting events.

By 1984, Maranta had been active in property development in Queensland for over fifteen years and was closely associated in business with former test cricketer and prominent Brisbane businessman, Greg Chappell.

In 1985, Barry Maranta expressed interest in fielding a Brisbane-based team in the New South Wales Rugby League's Winfield Cup premiership, the top-level rugby league football competition at the time. He was one of the principal owners of International Sports Management who had contributed to the advent of rugby league's State of Origin concept. In 1986, Maranta joined Paul Morgan, Gary Balkin and Steve Williams to form the Brisbane club. All men had played for Brisbane domestic teams. Four organisations made bids for the team which would be established in 1987. Ron McAuliffe, had the support of the NSWRL over the Maranta-Morgan group, other groups included 'International Syndicate' led by John Sattler and Bob Hagan, and one by Darryl van der Velde (who would later be CEO of the South Queensland Crushers).

When the NSWRL decided not to have a Brisbane club in 1987, the groups went down, but in a final bid for the 1988 season, both McAuliffe and Maranta-Morgan bid for the club. The NSWRL finally decided to have a Brisbane-based team and thus the Brisbane Broncos were born. The rights originally were going to go to the McAuliffe based group, but when it was realised that they didn't have the funds to support the club, it was given to Maranta-Morgan.

However, the Maranta-Morgan group did not please everybody, especially Australian Rugby League chairman Ken Arthurson, who decided to add other (now defunct) Queensland-based teams, Gold Coast for the 1988 season and the South Queensland Crushers in 1995 season.

Maranta was instrumental in the takeover of the ailing London Crusaders club in the English capital. London, who were founded as an offshoot of Fulham Football Club inside nine weeks and played their first competitive fixture in late August 1980, had a patchy existence until the company that owned the club went into receivership in the early spring of 1994.

The club, the only British professional rugby league club outside of the code's northern heartlands at the time, was run by the Rugby Football League while a new owner could be found. Maranta and his Brisbane colleagues saw London as a way into another top flight competition although London were playing in the second tier of British rugby league at the time.

Brisbane completed their takeover of London Crusaders in April 1994 and the renamed London Broncos began life in the August of that year. The interest of Maranta's fellow board members was proven to be short-lived however, and after London had been placed in the embryonic Super League (which was launched fully in the summer of 1996), his colleagues withdrew their interest. Maranta and fellow director Gary Balkin remained but Virgin Group founder Richard Branson took an initial stake in the club and later increased his holding to outright ownership after Maranta sold his interest in 1998.

Maranta returned to Australia. The London Broncos made their only Challenge Cup Final appearance so far at the old Wembley Stadium in May 1999, Branson relinquished his interest in 2001 and the London Broncos brand was 'retired' in September 2005, becoming Harlequins Rugby League under the ownership of Ian Lenagan.

Araneta Coliseum

The Araneta Coliseum, also currently known by naming rights sponsorship as Smart Araneta Coliseum, is an indoor multi-purpose sports arena that is part of the Araneta City in the Cubao area of Quezon City, Philippines. Nicknamed as "the Big Dome", it is one of the largest indoor arenas in Asia, and one of the largest clear span domes in the world. The dome measures approximately 108.0 m making it the largest dome in Asia from its opening in 1960 until 2001 when it was surpassed by the Ōita Stadium in Japan with a dome measuring 274.0 m.

The Smart Araneta Coliseum is mostly used for indoor sports such as basketball and volleyball. It is a main venue of the Philippine Basketball Association and for the basketball games of the National Collegiate Athletic Association and the University Athletic Association of the Philippines throughout various game seasons. The Big Dome is also used for other sports and events such as boxing, cockfighting, local and international concerts, circuses, religious gatherings, and beauty pageants.

History
In 1952, J. Amado Araneta, a member of the Araneta family, purchased from Radio Corporation of America (RCA) 35 hectare of land in Cubao which includes the Araneta family home and is bounded by Epifanio Delos Santos Avenue or EDSA, Aurora Boulevard, P. Tuazon and 15th Avenue. During this time, Araneta envisioned a multi-events venue inspired by the Madison Square Garden in New York City and the Roman Colosseum in Rome, Italy, which drew criticisms from his business advisers and even Amado's personal friends. This vision led to the development of business and lifestyle buildings surrounding the coliseum, which ultimately gave rise to the Araneta Center, now renamed as the Araneta City.

The Araneta Coliseum was constructed from 1957 to late 1959 and designed and built by Architect Dominador Lacson Lugtu and Engineer Leonardo Onjunco Lugtu. From 1960 to 1963, the Coliseum was recognized as the largest covered coliseum in the world. Today, it remains one of the largest clear span domes in the world with a dome diameter of 108 meters.

The coliseum opened on March 16, 1960, with Gabriel "Flash" Elorde boxing for the World Junior Lightweight crown against Harold Gomes. General admission then was 80 centavos, and the reserve section was five pesos. The total demand for people who wished to enter the coliseum to watch the boxing match live breached its capacity, wherein the total capacity of the coliseum was only 36,000 people, while the total number of people who came to the coliseum totaled to around 50,000 people. The coliseum also featured a swimming pool and a gazebo during its opening, located to the current site of the Araneta City Parking Garage South and the Novotel Manila Araneta City. However, the featured facilities closed down a few years later.

Among the notable events to take place at the arena were the 11th and 34th FAMAS Awards, the 1975 "Thrilla in Manila" boxing match between Muhammad Ali and Joe Frazier, in which the arena was renamed into the "Philippine Coliseum", and the annual Binibining Pilipinas beauty pageant. During the Thrilla in Manila, all of the 36,000 seats to watch the event live were sold out. Aside from boxing marches, the Philippine Basketball Association (PBA) has played most of their games at the Araneta Coliseum since its creation in 1975. Other basketball events hosted by the arena were the 1978 FIBA World Championship, a game between the 1978 NBA champions Washington Bullets and a PBA selection in 1979, and the 1982 Asian Youth Basketball Championship where the Philippines defeated China in the final.

In the third quarter of 1998, the Aranetas and Pilipinas Shell (local arm of Royal Dutch Shell) started negotiations for a naming rights deal that would have lasted until 2008. The Aranetas, who wanted to retain their name at the arena rejected the proposed name "Shell Coliseum at the Araneta Center". Instead, the parties agreed on a contract where Shell's name and logo will be painted at the arena's basketball court, a move that was almost shelved due to objections from other PBA teams because Shell owned the then-PBA team, the Shell Turbo Chargers.

In 1999, the Araneta Group initially planned to demolish the coliseum due to high amusement taxes and rising costs, which gave the company little revenue despite being subsidized by the company. The planned demolition was one of the proposals to the company in order to save funds for other business ventures. The plan was eventually scrapped in favor of the coliseum's renovation project. The coliseum underwent its first major renovation at the cost of ₱200 million. The major changes include the renovation of the lower box area, replacement of seats for the patron and lower box sections, and installation of a four-sided center-hung scoreboard. The section names were also given numerical designations: 100 for Patron section, 200 for Lower Box, 300 for Upper Box A, and 400 for Upper Box B. In 2006, an LED display was added to the scoreboard.

From 2001 to 2008, the highest-grossing event at the arena is the Pacquiao vs. Larios boxing fight between Manny Pacquiao and Óscar Larios, earning ₱96.2 million. A concert by Westlife was attended by 17,887 people and earned ₱18.5 million, while a Cliff Richard concert earned ₱17.2 million despite being watched by 5,647 spectators.

Prior to the Ultimate All-Star Weekend in July 2011, it was announced that the Aranetas entered into a naming rights deal with mobile network operator Smart Communications, Inc. (a subsidiary of Philippine Long Distance Telephone Company), renaming the arena into "Smart Araneta Coliseum". The 5-year naming rights deal includes improvements and renovations to the arena such as the installation of curved escalators to improve access in the upper box and general admission areas (the plan was subsequently cancelled due to undisclosed reasons), and the construction of a parking lot that can accommodate up to 2,000 cars. The overall renovation project of the coliseum costed ₱1 billion.

Additional improvements for the renovation of the coliseum were made in 2012, including the renovation of the Red Gate entrance and the Green Gate side facade, landscaped surroundings, and the replacement of Upper Box level seats, thus increasing its seating capacity. The Lower Box and Patron sections were combined to make a new Patron section (100 and 200 level seats). A pathway between the former Patron and Lower Box sections was also made. The former Upper Box A section (300 level seats) was renamed as Box section and the former Upper Box B section (400 level seats) is now referred to as the "Upper Box" section. The renovation project of the coliseum was completed in June 2014.

On January 7, 2015, the Hydra-Rib basketball backboards first used in 1995 were replaced with Spalding ones. The backboards were first used in Game 1 of the 2014–15 PBA Philippine Cup Finals. On June 9, 2017, the OES SHOTS-14G7 shot clocks were replaced. The newer clocks were first used in Game 3 of the 2017 PBA Commissioner's Cup Quarterfinals match between the TNT Katropa and Meralco Bolts.

Ahead of the 2023 FIBA Basketball World Cup, the Araneta Coliseum underwent renovation. Renovation works included the replacement of the previous "Big Cube" LED video board with a slightly larger one, as well as the refurbishment of seating areas and renovation of team dugouts. New upper box, lower box and general admission entrances connecting to Gateway Mall 2 were also built, as well as a new "Coliseum Plaza" a food hall located along the Red Gate entrance.

Architecture and design
The Araneta Coliseum is an indoor arena designed by Dominador Lacson Lugtu. The sports venue has a large span dome with a diameter of 108 m as its roof. The dome is 37 m high at its highest point. The structure is supported by 48 concrete columns and 48 metal ribs. It has a floor area of 2,300 sqm.

Richard de Leon of Atlantic, Gulf and Pacific did the steel framework of the venue – 4,965 aluminum sheets of gauge measuring 7.3 x was devised. Steam-treated wood from a variety of Philippine hardwood such as apitong, tanguile and narra fitted using tongue and groove was also used as support.

It was also one of the venues for the 2023 FIBA Basketball World Cup, which was co-hosted by the Philippines from August 25 to September 10, 2023. The tournament's final draw was held at the Coliseum on April 29, 2023. The arena hosted the first and 17th–32nd classification rounds.

Qualifiers

Boxing
The arena, which was temporarily renamed to "Philippine Coliseum" for the event, was the venue of the infamous Thrilla in Manila, the 1975 World Heavyweight Championship boxing match between Muhammad Ali and Joe Frazier. It was the third and final match of the three-bout rivalry between the two boxers and was held on October 1, 1975.

Ali won by corner retirement (RTD) after Frazier's chief second asked the referee to stop the fight after the 14th round. The bout is universally regarded as one of the best and most brutal fights in boxing history. It was reportedly watched by a total of 1 billion viewers, and by 50,000 people inside the arena, breaching the venue's total design capacity of 36,000 people.

Volleyball
Araneta Coliseum regularly hosts the UAAP Volleyball championships. It is one of the four primary venue for the Premier Volleyball League along with Filoil EcoOil Centre, PhilSports Arena, and Mall of Asia Arena.

He was recruited to the Balmain Tigers in 1953, playing 43 games for the team over four years until 1956.

Administration career
In 1956, Humphreys became secretary of the Balmain Tigers, holding the position until 1973, when he was appointed President of New South Wales Rugby League (NSWRL), Chairman of Australian Rugby League (ARL), and in 1976 NSWRL Executive Chairman. In 1973 he negotiated rugby league's first television deal with the Australian Broadcasting Corporation.

Scandal
In 1983, the Australian ABC-TV current affairs programme Four Corners, aired an episode entitled "The Big League". Reporter Chris Masters described allegations of corruption within the NSWRL, including suggestions that officials were siphoning funds from particular clubs and international matches, while players and spectators endured sub-standard facilities. Following the broadcast of the Four Corners program Humphreys resigned as Chairman of the NSWRL and ARL. He was replaced by Tom Bellew in the former position and by Ken Arthurson in the latter.

As a result of the program, a Royal Commission (the Street Royal Commission) was formed whose findings resulted in New South Wales chief magistrate Murray Farquhar being sent to prison, Humphreys' career ending abruptly and ABC being sued for libel by the then NSW State Premier, Neville Wran (who eventually settled out of court). Humphreys also received a $4000 fine and was placed on a "two year good behaviour bond". Humphreys later made a public apology.

Family
Humphreys is survived by his wife Joan and two sons David and Stephen. Stephen was CEO of the Wests Tigers between 2009 and 2012.

Death
Humphreys suffered from strokes for many months and had both legs amputated because of complications. He had suffered strokes which resulted in some paralysis prior to his death on 29 April 2010 at the age of 80 in a hospital in Sydney.

Jason Smith (baseball)

Jason William Smith (born July 24, 1977) is an American former Major League Baseball infielder.

Career
In 1995, Smith was drafted by the Los Angeles Dodgers in the 42nd round of the 1995 Major League Baseball Draft, but did not sign. A year later, he was drafted by the Chicago Cubs in the 23rd round of the 1996 Major League Baseball Draft. He made his major league debut with the Cubs on June 17, 2001.

After stints in Tampa Bay, Detroit and Colorado, Smith was claimed in the Rule 5 Draft by Toronto in December 2006.

Smith was claimed off waivers by Arizona on May 15, 2007. He played 2 games for the Diamondbacks going 1-4 before being placed on the disabled list. On July 11, 2007, while on the disabled list, he was claimed off waivers by the Kansas City Royals, for whom he batted .188 in 2007 and .214 in 2008.

He became a free agent after the 2008 season and signed a minor league contract with the Houston Astros on January 5, 2009.

On May 10, 2009, Smith was recalled to Houston for added depth as Lance Berkman suffered a wrist injury.

Personal life
Smith's cousin, Austin Davis, plays in the NFL. He currently resides in Mobile, Alabama.

Hamarhus

Hamarhus at Hamar in Hedmark, Norway was originally the fortified palace of the Bishop of the Ancient Diocese of Hamar. It is now the site of Storhamarlåven, an exhibit of Anno Museum.

History
The palace was east for Hamar Cathedral, and was linked to the cathedral. The palace was constructed in stages, the oldest parts of stonework was erected around 1250 or a little later, and consists of three vault cellars white wooden roofing, and a large castle tower with ground floor approx, 10 x 18 m, with basement. After the reformation, the former bishop's residence was used by the local Lensherren. Both Hamarhus and Hamar Cathedral were destroyed in 1567 by the Swedish armies during the Northern Seven Years' War. The ruins of Hamarhus were later converted into the barn and outbuilding on Storhamar farm. The barn was built in the 18th and 19th century, using the ruins of the medieval bishop's palace as parts of the walls.

Storhamarlåven
The Storhamar barn (Storhamarlåven) and former farm buildings were converted into a museum between 1967 and 1979. Storhamarlåven was designed by architect Sverre Fehn (1924–2009) in concrete, wood and glass to contrast with the stone of the medieval ruins. Sverre Fehn included modern installations while preserving historical remain as well as providing the further archeological excavations. Construction work began in 1969, the barn was completed in 1971 and the south wing with the auditorium in 1973. The exhibitions were completed in 1979.

Talk:Quadric

Hyperbolic Parabaloid and Affine Transformations
"Geometrically, every non-degenerate quadric surface is obtained from a conic section in the plane as a surface of revolution, followed by an affine transformation."

I am skeptical. What are the conic section and affine transformation that produces a hyperbolic parabaloid?

192.249.47.195 (talk) 18:46, 28 September 2009 (UTC)

Conic section embedded in R^3
I couldn't find this in the article: Given a quadric equation in three dimensions, what are the necessary and sufficient conditions on the parameters or parameter matrix for it to describe a conic in a two-dimensional flat of R^3? And what further conditions on the matrix characterize the different types of conics? Loraof (talk) 17:59, 15 October 2014 (UTC)

 * I'm not clear on what exactly you are asking. Do you want the conditions for a homogeneous quadratic in three-dimensions?  The coefficient matrix is then 3×3, and the condition is that it be a non-singular (strictly) semi-definite matrix (that is, with eigenvalues of both positive and negative sign).  Then any plane that avoids the origin cuts that cone in a conic section.  If the question is rather about a non-homogeneous quadratic polynomial in three variables, then such a thing comes from a homogeneous polynomial of four variables.  Then there are two cases of the eigenvalues to consider, (++--) and (+++-).  In the first case, the quadric is ruled by two families of lines (think the lines on a hyperbolic paraboloid or a hyperboloid of one sheet).  As long as the plane you choose does not contain any line in either the family, it will cut out a conic.  In the other case, reality becomes important (think of a plane that does not cut an elliptic paraboloid).  In that case, you can restrict the quadric to the plane (say, writing everything in terms of x and y).  That gives you a quadric in the plane, and the condition for that quadric to be a conic is that the coefficient matrix should be non-singular (and strictly semi-definite).   Sławomir Biały  (talk) 22:05, 15 October 2014 (UTC)

 * Thanks. Given

 * $$Ax^2+By^2+Cz^2+Dxy+Exz+Fyz+Gx+Hy+Iz+J=0$$

 * in scalars, or if you prefer

 * $$x^TQx+x^TR+S=0$$

 * for 3×1 vector x, 3×3 matrix Q, 3×1 column vector R, and scalar S, under what conditions do all the points fall in a single plane?

 * Thanks, Loraof (talk) 01:07, 16 October 2014 (UTC).

 * For this to describe a plane, the matrix $$\begin{bmatrix}Q&R/2\\ R^2/2& S\end{bmatrix}$$ must have rank one.  Sławomir Biały  (talk) 11:17, 16 October 2014 (UTC)

Definition of a quadric (recent change)
A pair of planes in (3-space) is a quadric ! (s. recent change). --Ag2gaeh (talk) 14:05, 2 March 2017 (UTC)

 * Can you reliably source your assertion? A far as I know, for most authors, a quadric is an algebraic variety, and thus defined by an irreducible quadratic polynomial. A pair of planes is an algebraic set that is not an algebraic variety. Moreover, during centuries, before 20th century, quadric were considered in a purely geometric way (that is by considering equations only when they are not avoidable) and in this context, it is a non-sense to consider a pair of planes as a quartic. Also, the study of the quartics was aimed to study (and classify) the simplest non-plane surfaces; it seems absurd to qualify a pair of planes as a non-plane surface. D.Lazard (talk) 16:51, 2 March 2017 (UTC)

 * My calculus textbook indicates that such a set is degenerate: "In three-space . . . any second-degree equation which does not reduce to a cylinder, plane, line, or point corresponds to a surface which we call quadric.  Quadric surfaces are classified into six types, and it can be shown that every second-degree equation which does not degenerate into a cylinder, a plane, etc., corresponds to one of these six types." — Anita5192 (talk) 17:55, 2 March 2017 (UTC)

 * This is a case where terminology is not uniformly fixed. IMO, there are two methods to find the dominant one. The first is is boring, and consists in consult many textbooks for extracting the dominant terminology. The second one is to look what is meant in the articles that use the terms without defining them. As authors of good paper use a term without defining it only if it is not ambiguous, this is a good indication of the standards. I know that, when I read "quadric" in a paper, this should mean one of the five non-degenerated quadrics (six, if imaginary ellipsoid is relevant in the context). When cones and cylinders must be taken into account, authors generally use "quadratic surface". In this case, only the context allows knowing if non-irreducible quadratic algebraic sets should be included. I have tried to take this into account in my edit, but some clarification is certainly still needed. In particular the distinction between "quadric" and "quadratic surface" deserve to be mentioned. D.Lazard (talk) 19:13, 2 March 2017 (UTC)

 * For example: Oswald Giering Vorlesungen über höhere Geometrie, Springer-Verlag,p. 61.
 * Is a conic section a quadric ? In German text-books there are pairs of lines (planes in space) quadrics. Is there a cultural gap ?--Ag2gaeh (talk) 19:15, 2 March 2017 (UTC)

 * The English definition of a quadric NOW does not comply with all (?) other WIKIs. And there is a contradiction: The definition excludes pairs of planes, the list of quadrics below contains such objects. There are two major subclasses of quadrics: nondegenerate and degenerate. Both are quadrics. --Ag2gaeh (talk) 09:32, 3 March 2017 (UTC)

The numbers don't add up
The section Quadric starts out by giving some equations and permissible epsilon values, for a total of 17 possibilities. Then it mentions "these 17 normal forms", and mentions 7 of them that are imaginary only, single-real-point, or otherwise trivial. That leaves 10 remaining. Then the next paragraph begins "Thus, there are nine true quadrics", and specifies these as 4 degenerate quadrics and 5 non-degenerate ones, "which are detailed in the following table". Then a paragraph says "there are 17 such normal forms. Of these 16 forms, ...". Then a table is given, consisting of a non-degenerate section containing 10 and a degenerate section containing 6.

I hope that someone familiar with these can clarify how these different passages relate to each other numerically, and which ones in one passage coincide with which ones in each other passage. Loraof (talk) 23:25, 17 October 2017 (UTC)

 * I have added the lacking case ($$\varepsilon_3=0$$). I have also replaced the last paragraph before the table by a summary of the classification. In fact, this paragraph classified implicitly the imaginary ellipsoid among the degenerate quadrics, which contradicts the definition of "degenerate" given in Degeneracy (mathematics). Also, it is unclear whether the decomposed quadrics should be, or not, included in the degenerated one. It is therefore better to have a formulation that avoids having to decide.
 * About the table: If one omits the "special cases", the table gives 5 non-degenerate and 3 degenerate quadrics. It could be less confusing to move the special cases in one or two specific sections of the table. D.Lazard (talk) 10:04, 18 October 2017 (UTC)

 * Great job – thanks! Loraof (talk) 14:59, 18 October 2017 (UTC)

Color Mismatch
The colors in the image in the Euclidean Plane section are mismatched from the description of the image. 209.6.73.123 (talk) 22:49, 4 September 2018 (UTC)

 * It is fixed now. Thank you for pointing this out.—Anita5192 (talk) 23:28, 4 September 2018 (UTC)

 * Perhaps the color "goldenrod" is better: $$\color{goldenrod}{abc}$$. Please try or look at Help:Displaying a formula. --Ag2gaeh (talk) 07:24, 5 September 2018 (UTC)

 * Goldenrod is less difficult to see, but still difficult. Actually I don’t think the image needs a color-coordinated caption.  If the colors are completely removed from the caption, the specific eccentricities clarify the correspondence.  I suggest we make the caption text entirely black.—Anita5192 (talk) 16:05, 5 September 2018 (UTC)

Revision of section "Projective quadrics over fields"
I tried to improve section Projective quadrics over fields. If there is no objection, I shall remove the tag on "multiple issues".--Ag2gaeh (talk) 09:56, 2 March 2019 (UTC)

Grammar and/or Spelling
In the current version of the article I read the sentence: "This define affine quadrics." Either grammatically or spelling-wise there seems to be an error in this sentence, which obscures its meaning to me. What did the author intend to write?

Was it "This defines affine quadrics."?

Or was it "These define affine quadrics."?

Or anything else?Redav (talk) 09:14, 26 April 2020 (UTC)
 * The first interpretation is the correct one. However, as "This" is ambiguous, I have moved the definition at the beginning of the section, and added explanations for clarifying the end of the section. D.Lazard (talk) 09:48, 26 April 2020 (UTC)

Rational Parametrization
I'm not 100% sure that the recent efforts qualify as an improvement yet, but thank you for the work ... let's keep at it! Some questions: — Q uantling (talk | contribs) 00:47, 28 November 2022 (UTC)
 * 1) I have no problem assuming that $$t_0 = 1$$ for points not at infinity, but why is it okay to assume $$t_n = 1$$?  That is, won't that miss some not-at-infinity points of the quadric if we disallow $$T_n = 0$$?  (Alternatively, if we somehow know that $$T_n = 0$$ always gives something that is tangent to the quadric at $$A$$, let's explain that.)
 * 2) "This pametrization establishes a bijection between a projective conic section and the projective line" -- Each point of the quadric (not in the tangent hyperplane of $$A$$) is one-to-one with a line through the origin, e.g., a point in projective space, right?
 * 3) Is "projective conic section" the same as "quadric"?  If so, let's consistently use the latter.
 * 4) In, cases b and c are not both called "tangent" but they are in this newly rewritten section.  Let's say something about this difference of usage, or otherwise make things more consistent.
 * 5) Do you have literature that refers to this as "rational parametrization"?  Given that it is a mapping from (most of) the quadric to a projective space, the natural name for it (to me) is a "projection".

 * There is no $$t_0$$ and no $$T_0$$ Howeverm I have added some clarification. Normally, this clarification should belong to another article, such as Parametric equation (not explained there) or Rational variety (explained there, in a much too technical way). This is explained in a special case in Möbius transformation.
 * This is a bijection between the points of the projective conic section and the points of the projective line. The fact that the points of projective spaces are often defined as vector lines has nothing to to here.
 * A quadric may have any dimension. A conic section is a quadric of dimension one.
 * The last sentence of contradicts the beginning of the section. So, this is this section that must be edited. Neverttheless I have added a clarification.
 * "Rational parametrization" is a standard terminology that is used in several Wikipedia articles. So, I have created the redirect which redirects to the first occurence of the phrase in Rational variety. Also "rational parametric equation" occurs in Parametric equation. So, the target of the new redirect could be changed to Parametric equation after having edited this article. I have linked the section to this redirect.
 * D.Lazard (talk) 10:55, 28 November 2022 (UTC)

 * thank you for your replies and article edits. Regarding Question 1, elsewhere in the article we number the non-projective dimensions as $1$ to $n$ and then use the index of $0$ for the additional dimension used in projective geometry, whose value is typically $1$ for points not at infinity and is $0$ for points at infinity.  I admit to confusion for the present case ... is the use of index $n$ in the present section different from this use of $0$ elsewhere ... or should it be changed to $0$ for consistency with the rest of the article?  I apologize for not quite following this well enough that I can answer my own question.

 * Regarding Question 2, with "This pametrization establishes a bijection between a projective conic section and the projective line", might we instead say more generally that "This pametrization establishes a bijection between a quadric and a projective space"? Also, what should we do about the caveat that the points in the tangent hyperplane are excluded? — Q uantling (talk | contribs) 17:29, 28 November 2022 (UTC)
 * Point 1: the $$t_i$$ are the coordinates of a direction vector in the space that contains the quadric. So the $$t_i$$ must be indexed in the same way as the space coordinates $$x_i.$$ As the directions form a projective space of dimension $$n-1,$$ one must equal one of the $$t_i$$ to 1 for having affine parameters. It is $$t_n$$ that has been equated to 1, since otherwise one would not have an indexing by the first positive integers.
 * Point 2:Your second question is the answer to the first one: in general, the parametrization does not cover the whole quadric; that is, the points of the intersection of the quadric and its tangent hyperplane at $A$ are not parametrized. However, I have fixed an error: not every point of the projective space ot the parameters gives a point of the quadric: the directions contained in the tangent hyperplane at $A$ do not give any point of the quadric. D.Lazard (talk) 10:39, 29 November 2022 (UTC)
 * I have added examples as a new subsection. This should be a clarification for many readers. D.Lazard (talk) 16:52, 29 November 2022 (UTC)
 * Thank you, this is coming along nicely. Another question (to demonstrate my ignorance): if $A$ is a non-singular point of the quadric, is it impossible that the line $a + λt$ is completely contained within the quadric?  — Q uantling (talk | contribs) 23:33, 29 November 2022 (UTC)
 * Consider the hyperbolic paraboloid $$z=xy$$ and $$A=(0,0,0).$$ the two lines $$(\lambda,0,0)$$ and $$(0,\lambda,0)$$ are contained in the quadric. More generally, for every point of a hyperbolic paraboloid or a one-sheet hyperboloid, there are there are two line passing through the point and contained in the quadric. The same is true for every non-degenerate quadric surface, if one considers nonreal complex points. D.Lazard (talk) 09:33, 30 November 2022 (UTC)

Heronian triangles
has recently added the following paragraph in section : "A Heronian triangle is a triangle whose side lengths and area are integers. The interior angles of a Heronian triangle have half-angle tangents, $x_1,$ $x_2,$ and $x_3,$ that are rational and satisfy the quadratic relationship $x_1 x_2 + x_2 x_3 + x_1 x_3 = 1.$ Thus rational parametrization can be used to generate all such triples of rational tangents.  These in turn give rational side lengths $\frac{2x_1}{1+x_1^2}\,,$ $\frac{2x_2}{1+x_2^2}\,,$ and  $\frac{2x_3}{1+x_3^2}$ and a rational area $\frac{4x_1 x_2 x_3}{(1+x_1^2)(1+x_2^2)(1+x_3^2)}$ for a triangle with those half-angle tangents.  This triangle can be scaled to a similar triangle whose side lengths and area are integers."

I'll remove this paragraph because of the following issues, which, all together, make that this paragraph does not belong to this section. D.Lazard (talk) 15:49, 2 December 2022 (UTC)
 * The section is about rational points of quadrics, and the primitive Heronian triangles are in one to one correspondence with the rational points of the quartic obtained by squaring Heron's formula. As a quartic is not a quadric, the relationship between Heronian triangles and rational points (the subject of this section) does not belong to this article.
 * The assertions contained in the paragraph are true, but not evident (I had to think about a while for finding a proof). So they must be sourced, proved, linked, or easy to find in Heron triangle. This is not the case, and the paragraph does follows the policy of WP:Verifiability.
 * It is not said that the relation $$x_1 x_2 + x_2 x_3 + x_1 x_3 = 1$$ is satisfied by half-angle tangents of every triangle.
 * Parametrizing this quadric does not requires the method described in this article, as the parametrization $x_1=t, x_2=u, x_3=\frac{uv}{u+v}$ is evident.
 * Several rational parametrizations of the "Heronian quartic" are given in Heronian triangle, but it is unclear whether any of them results from a paramatrization of the quadric $$x_1 x_2 + x_2 x_3 + x_1 x_3 = 1.$$ So this way of parametrizing heronian triangles seems WP:OR.

 * I agree that if it isn't WP:CALC then an editor can request that there be a citation. Go ahead and remove it if you wish.  It's been a while since I've had my algebraic varieties class, so odds are long that I will find a Wikipedia-quality citation, but I'll keep my eyes open.  (Yes, we could clarify that $$x_1 x_2 + x_2 x_3 + x_1 x_3 = 1$$ is satisfied by every triangle; it leads to a Heronian triangles if and only if each of the variables is positive and rational.  Yes, there is a way to frame Heronian triangles as using a quartic equation, but that doesn't make the quadratic approach any less valuable.  Yes, there are other ways to solve this quadratic, but there are other ways to solve the circle too; e.g., $$x_1 = u,$$ $$x_2 = \pm\sqrt{1-u^2}$$) — Q uantling (talk | contribs) 16:21, 2 December 2022 (UTC)

I hope someone adds information about the standard quadric
The standard quadric in complex (n+1)-space C^(n+1) is defined as the set of points (z_0, ..., z_n) in C^(n+1) such that z_0^2 + ... + z_n^2 =  0.

Likewise since z_0^2 + ... + z_n^2 is a homogeneous polynomial, the standard quadric may alternatively be seen as a complex projective hypersurface in complex projective (n+1)-space CP^(n+1).

This is an important construction in mathematics and should not be omitted from the article. 2601:200:C082:2EA0:50AA:AEB:9A5D:EB80 (talk) 03:41, 18 February 2023 (UTC)

 * For adding such information, one requires
 * A reliable source attesting that "standard quadric" is a common name forthis concept (Looking on Scholar Google, I did not find any source using "standard quadric" in this sense)
 * Notable properties of these hypersurfaces that deserve to be added in this article
 * As far as I know, the main property of what you call "standard quadric" is already in the article, stated as . This means that, up to complex projective transformations, the standard quadrics are exactly the nondegenerate quadrics D.Lazard (talk) 10:39, 18 February 2023 (UTC)
