Arabic is a Semitic language spoken primarily across the Arab world. Having emerged in the 1st century, it is named after the Arab people; the term "Arab" was initially used to describe those living in the Arabian Peninsula, as perceived by geographers from ancient Greece.
In mathematics, convolution is a mathematical operation on two functions that produces a third function that expresses how the shape of one is modified by the other. The term convolution refers to both the result function and to the process of computing it. It is defined as the integral of the product of the two functions after one is reflected about the y-axis and shifted. The choice of which function is reflected and shifted before the integral does not change the integral result. The integral is evaluated for all values of shift, producing the convolution function.
G, or g, is the seventh letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is gee, plural gees.
The International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of speech sounds in written form. The IPA is used by lexicographers, foreign language students and teachers, linguists, speech–language pathologists, singers, actors, constructed language creators, and translators.
In physics, the kinetic energy of an object is the form of energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest. Formally, a kinetic energy is any term in a system's Lagrangian which includes a derivative with respect to time and the second term in a Taylor expansion of a particle's relativistic energy.
The lion is a large cat of the genus Panthera native to Africa and India. It has a muscular, broad-chested body; short, rounded head; round ears; and a hairy tuft at the end of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called prides. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on large ungulates. The lion is an apex and keystone predator; although some lions scavenge when opportunities occur and have been known to hunt humans, lions typically do not actively seek out and prey on humans.
Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Big O is a member of a family of notations invented by Paul Bachmann, Edmund Landau, and others, collectively called Bachmann–Landau notation or asymptotic notation. The letter O was chosen by Bachmann to stand for Ordnung, meaning the order of approximation.
In physics and mathematics, the Fourier transform (FT) is a transform that converts a function into a form that describes the frequencies present in the original function. The output of the transform is a complex-valued function of frequency. The term Fourier transform refers to both this complex-valued function and the mathematical operation. When a distinction needs to be made the Fourier transform is sometimes called the frequency domain representation of the original function. The Fourier transform is analogous to decomposing the sound of a musical chord into terms of the intensity of its constituent pitches.
The Group of Eight (G8) was an inter-governmental political forum from 1997 until 2014. It had formed from incorporating Russia into the Group of Seven, or G7, and returned to its previous name after Russia was expelled in 2014.
Christopher George Latore Wallace, better known by his stage names the Notorious B.I.G., Biggie Smalls, or simply Biggie, was an American rapper. Rooted in East Coast hip hop and particularly gangsta rap, he is cited in various media lists as one of the greatest rappers of all time. Wallace became known for his distinctive laid-back lyrical delivery, offsetting the lyrics' often grim content. His music was often semi-autobiographical, telling of hardship and criminality, but also of debauchery and celebration.
In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
The Mikoyan MiG-29 is a twin-engine fighter aircraft designed in the Soviet Union. Developed by the Mikoyan design bureau as an air superiority fighter during the 1970s, the MiG-29, along with the larger Sukhoi Su-27, was developed to counter new U.S. fighters such as the McDonnell Douglas F-15 Eagle and the General Dynamics F-16 Fighting Falcon. The MiG-29 entered service with the Soviet Air Forces in 1983.
In thermodynamics, the Gibbs free energy is a thermodynamic potential that can be used to calculate the maximum amount of work, other than pressure-volume work, that may be performed by a thermodynamically closed system at constant temperature and pressure. It also provides a necessary condition for processes such as chemical reactions that may occur under these conditions. The Gibbs free energy is expressed as where p is pressure, T is the temperature, U is the internal energy, V is volume, H is the enthalpy, and S is the entropy.
The 2003 NBA draft was held on June 26, 2003, at The Theater at Madison Square Garden in New York City, New York. The NBA announced that 41 college and high school players and a record 31 international players had filed as early-entry candidates for the 2003 NBA draft. The Cleveland Cavaliers, who had a 22.50 percent probability of obtaining the first selection, won the NBA draft lottery on May 22, and Cleveland chairman Gordon Gund said afterward his team would select LeBron James. The Detroit Pistons and the Denver Nuggets were second and third, respectively. This draft was the first draft to be aired on ESPN after they picked up the license from TNT.
The Group of Seven (G7) is an intergovernmental political forum consisting of Canada, France, Germany, Italy, Japan, the United Kingdom and the United States; additionally, the European Union (EU) is a "non-enumerated member." It is organized around shared values of pluralism, liberal democracy, and representative government. As of 2020, G7 members are large IMF advanced economies and account for over half of global net wealth, 30 to 43 percent of global gross domestic product, and 10 percent of the world's population. Some members are great powers in global affairs and maintain mutually close political, economic, diplomatic, and military relations.
The G20 or Group of 20 is an intergovernmental forum comprising 19 countries and the European Union (EU). It works to address major issues related to the global economy, such as international financial stability, climate change mitigation, and sustainable development.
Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measured with a thermometer.
In telecommunications, 5G is the fifth-generation technology standard for broadband cellular networks, which cellular phone companies began deploying worldwide in 2019, and is the planned successor to the 4G networks which provide connectivity to most current cellphones.
EE is a British national mobile network operator and internet service provider, which is a brand within the BT Group. EE is the second-largest mobile network operator in the United Kingdom, with 21.7 million subscribers as of March 2023.
Rebbeca Marie Gomez, known professionally as Becky G, is an American singer and actress. She first gained recognition in 2011 when she began posting videos of herself covering popular songs online. One of her videos caught the attention of record producer Dr. Luke, who subsequently offered her a record deal with Kemosabe Records in a joint venture with RCA Records. While working on her debut effort, Gomez collaborated with artists will.i.am, Cody Simpson and Cher Lloyd. In 2013, she released her debut commercial single, "Becky from the Block", to positive reception. Later that year, she released her debut extended play, Play It Again. Her second single and first in 2014, "Can't Get Enough", featured guest vocals from Pitbull and went on to top the Latin Rhythm Airplay chart in the United States.
