In probability theory and statistics, the multivariate normal distribution, multivariate Gaussian distribution, or joint normal distribution is a generalization of the one-dimensional normal distribution to higher dimensions. One definition is that a random vector is said to be k-variate distributed if every linear combination of its k components has a univariate normal distribution, its importance derives from the multivariate central limit theorem. The multivariate normal distribution is used to describe, at least any set of correlated real-valued random variables each of which clusters around a mean value; the multivariate normal distribution of a k-dimensional random vector X = T can be written in the following notation: X ∼ N, or to make it explicitly known that X is k-dimensional, X ∼ N k, with k-dimensional mean vector μ = E ⁡ =, k × k covariance matrix Σ i, j:= E ⁡ = Cov ⁡ such that 1 ≤ i, j ≤ k. The inverse of the covariance matrix is called the precision matrix, denoted by Q = Σ − 1.

A real random vector X = T is called a standard normal random vector if all of its components X n are independent and each is a zero-mean unit-variance distributed random variable, i.e. if X n ∼ N for all n. A real random vector X = T is called a centered normal random vector if there exists a deterministic k × ℓ matrix A such that A Z has the same distribution as X where Z is a standard normal random vector with ℓ components. A real random vector X = T is called a normal random vector if there exists a random ℓ -vector Z, a standard normal random vector, a k -vector μ, a k × ℓ matrix A, such that X = A Z + μ. Formally: Here the covariance matrix is Σ = A A T. In the degenerate case where the covariance matrix is singular, the corresponding distribution has no density; this case arises in statistics. The X i are in general not independent.

Bonner went to Auburn University, she was named to the SEC All-Freshman Team. She scored in double figures in 22 games during the 2005–06 season and led the Tigers with a 13.5 points per game average, the first time since 1980–81 that a freshman led the team in scoring.

This led Bonner to join the youth teams of US basketball, winning the 2006 FIBA Americas Under-20 Championship for Women and the FIBA Under-21 World Championship for Women one year later. Bonner went on to put together one of the most impressive careers at Auburn; the 2009 SEC Player of the Year and a National Player of the Year finalist, she broke the Auburn career scoring record during the Ole Miss game at the SEC Tournament. She finished her career with 2,162 points, nearly 100 more than the former school record, she finished her career as one of Auburn's top rebounders, taking second all-time with 1,047 rebounds, placing her among three Tigers to finish their career with more than 2,000 points and 1,000 rebounds. Listed in the top 10 in every major statistical category at Auburn, she ranks sixth in blocks, seventh in steals, first in free throws, fourth in field goals and 10th in 3-pointers. Bonner led the SEC in scoring that season, becoming the first Auburn player to earn the honor, she ranked 10th in the country in scoring while setting the Auburn single-season scoring record with 716 points, 21.1 per game.

She went on to earn WBCA/State Farm, USBWA, AP and ESPN.com All-America honors and was voted the Alabama Sports Writers Association Amateur Athlete of the Year. Source Bonner was selected 5th overall in the 2009 WNBA Draft by the Phoenix Mercury. In her first regular season game with the Mercury, Bonner scored 16 points. October 9, 2009, as a rookie, Bonner scored 13 points to contribute toward the 2009 championship. On September 12, 2014, Bonner won her second WNBA Championship, with 12 points, 9 rebounds and 3 assists. In 2017 Bonner sat out the whole season due to pregnancy, she would be voted into the 2018 WNBA All-Star Game. On in the season, the Mercury made the playoffs as the fifth seed and were one game away from reaching the finals as they lost in five games to the Seattle Storm in the semi-finals. On February 11th, 2020 Bonner was traded to the Connecticut Sun for 3 first round draft picks. During the WNBA offseason, Bonner has played in the Czech Republic for BK Brno, Spain for Baloncesto Rivas and CB Avenida, Russia for Nadezhda Orenburg

Ralph 124C 41+, by Hugo Gernsback, is an early science fiction novel, written as a twelve-part serial in Modern Electrics magazine, which Gernsback edited, beginning in April 1911. It was compiled into novel/book form in 1925. While it pioneered many ideas found in science fiction, it has been critically panned for its "inept writing"; the title itself is a play on words, meaning "One to foresee for one another". In the introduction to the first volume of Science-Fiction Plus, dated March 1953, Gernsback called for patent reform to give science fiction authors the right to create patents for ideas without having patent models because many of their ideas predated the technical progress needed to develop specifications for their ideas; the introduction referenced the numerous prescient technologies described throughout Ralph 124C 41+. The eponymous protagonist saves the life of the heroine by directing energy remotely at an approaching avalanche; as the novel goes on, he describes the technological wonders of the modern world using the phrase "As you know..."

The hero rescues the heroine by travelling into space on his own "space flyer" to rescue her from the villain's clutches. Some successful predictions from this novel include television, remote-control power transmission, the videophone, transcontinental air service, solar energy in practical use, sound movies, synthetic milk and foods, artificial cloth, tape recorders, spaceflight, it contains "...the first accurate description of radar, complete with diagram...", according to Arthur C. Clarke in his "non-genre" novel Glide Path. "A pulsating polarized ether wave, if directed on a metal object can be reflected in the same manner as a light-ray is reflected from a bright surface or from a mirror..." Some of the science predictions made in the story turned out to be wrong. For example, in 1911 it was assumed that, just as a sound wave needed a medium to travel in, so did a light wave. Ether was postulated as the unknown substance. In the story an ether vacuum occurred. Radiation caused more ether to be drawn to an area of energy expenditure and the lack of ether resulting from this overusage caused a temporary blackout because light could not travel where there was no ether.

Heat and cold could not be transferred during such a blackout. It is now known that such ether is not needed for light to travel; such effects are impossible. Though Ralph 124C 41+ has been described as pioneering many of the tropes and ideas found in science fiction works, it has been neglected due to what critics describe as poor artistic quality. Brian Aldiss has called the story a "tawdry illiterate tale" and a "sorry concoction" while Lester del Rey called it "simply dreadful". Martin Gardner referred to the book as "surely the worst SF novel written". Groff Conklin more generously described it as "thoroughly delightful... the genuine charm of a sound, workmanlike antique."Reviewing the 1950 Frederick Fell edition in the New York Times, Rex Lardner wrote that while the "fine" novel "contain a good deal of sound prophecy... it has a narrative style as quaint as the retarder on a Hupmobile." Everett F. Bleiler noted that "The literary treatment is on a low level, but Ralph 124C41+ is renowned for its many imaginative technical projections."While most critics have little positive to say about the story's writing, Ralph 124C 41+, Gary Westfahl, one of the book's few public defenders, considered it "essential text for all studies of science fiction" and The Economist called it "arguably the first major work of American science fiction".

According to Westfahl, "the novel merits attention because of the ways Gernsback uneasily blended several generic models – melodrama, the travel tale, Utopia touches of Gothic and Satire – in an effort to achieve a workable vehicle for a story emphasizing scientific facts and predictions. In this way, the novel foreshadows and makes explicit many of the generic tensions that permeate sf." Accelerated Plant Growing Farms: Huge greenhouse farms used to feed the growing Earth population.
