Entropy is a scientific concept as well as a measurable physical property that is most commonly associated with a state of disorder, randomness, or uncertainty. The term and the concept are used in diverse fields, from classical thermodynamics, where it was first recognized, to the microscopic description of nature in statistical physics, and to the principles of information theory. It has found far-ranging applications in chemistry and physics, in biological systems and their relation to life, in cosmology, economics, sociology, weather science, climate change, and information systems including the transmission of information in telecommunication.
Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency to emphasize the contrast to spatial frequency, and ordinary frequency to emphasize the contrast to angular frequency. Frequency is measured in hertz (Hz) which is equal to one (event) per second. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency. For example, if a heart beats at a frequency of 120 times a minute, its period, T—the time interval between beats—is half a second. Frequency is an important parameter used in science and engineering to specify the rate of oscillatory and vibratory phenomena, such as mechanical vibrations, audio signals (sound), radio waves, and light.
Tracy Lauren Marrow, better known by his stage name Ice-T, is an American rapper, songwriter, actor and producer. He began his career as an underground rapper in the 1980s and was signed to Sire Records in 1987, when he released his debut album Rhyme Pays—reportedly the first hip-hop album to carry an explicit content sticker. The following year, he founded the record label Rhyme $yndicate Records and released another album, Power, which would go platinum. He also released several other albums that went gold.
Mr. T, is an American actor, television personality, and retired bouncer, bodyguard and professional wrestler. He is known for his roles as B. A. Baracus in the 1980s television series The A-Team and as boxer Clubber Lang in the 1982 film Rocky III. He is also known for his distinctive hairstyle inspired by Mandinka warriors in West Africa, his copious gold jewelry, his tough-guy persona and his catchphrase "I pity the fool!", first uttered as Clubber Lang in Rocky III, then turned into a trademark used in slogans or titles, like the reality show I Pity the Fool in 2006.
In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.
Thomas Stearns Eliot was a poet, essayist, publisher, playwright, literary critic and editor. Considered one of the 20th century's major poets, he is a central figure in English-language Modernist poetry.
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment, moment of force, rotational force or turning effect, depending on the field of study. It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers. Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the force and the perpendicular distance of the line of action of a force from the axis of rotation. The symbol for torque is typically , the lowercase Greek letter tau. When being referred to as moment of force, it is commonly denoted by M.
Tyrannosaurus is a genus of large theropod dinosaur. The species Tyrannosaurus rex, often called T. rex or colloquially T-Rex, is one of the best represented theropods. Tyrannosaurus lived throughout what is now western North America, on what was then an island continent known as Laramidia. Tyrannosaurus had a much wider range than other tyrannosaurids. Fossils are found in a variety of rock formations dating to the Maastrichtian age of the Upper Cretaceous period, 68 to 66 million years ago. It was the last known member of the tyrannosaurids and among the last non-avian dinosaurs to exist before the Cretaceous–Paleogene extinction event.
Booker Taliaferro Washington was an American educator, author, orator, and adviser to several presidents of the United States. Between 1890 and 1915, Washington was the dominant leader in the African American community and of the contemporary black elite. Washington was from the last generation of black American leaders born into slavery and became the leading voice of the former slaves and their descendants. They were newly oppressed in the South by disenfranchisement and the Jim Crow discriminatory laws enacted in the post-Reconstruction Southern states in the late 19th and early 20th centuries.
In mathematics, a Fourier transform (FT) is a mathematical transform that decomposes functions depending on space or time into functions depending on spatial or temporal frequency, such as the expression of a musical chord in terms of the volumes and frequencies of its constituent notes. The term Fourier transform refers to both the frequency domain representation and the mathematical operation that associates the frequency domain representation to a function of space or time.

WarnerMedia, LLC is an American multinational mass media and entertainment conglomerate corporation owned by AT&T and headquartered at the 30 Hudson Yards complex in New York City, United States.
Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetic and strong forces.
Clifford Joseph Harris Jr., better known by the stage names T.I. and Tip, is an American rapper, record executive, and actor. Harris, one of the highest selling hip-hop artists of all time, is also known as one of the pioneers of the hip hop subgenre trap music, along with fellow Atlanta-based rappers Jeezy and Gucci Mane. Harris signed his first major-label record deal in 1999 with Arista Records subsidiary LaFace. In 2001, he released his debut album and only project with the label, I'm Serious, as well as forming the southern hip hop group P$C. Upon being dropped from Arista, Harris signed to Atlantic and soon co-founded his own label imprint, Grand Hustle Records, which he launched in 2002.
In linear algebra, an eigenvector or characteristic vector of a linear transformation is a nonzero vector that changes at most by a scalar factor when that linear transformation is applied to it. The corresponding eigenvalue, often denoted by , is the factor by which the eigenvector is scaled.
