Entropy is a scientific concept 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, most often measured in hertz, is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency for clarity and to distinguish it from spatial frequency. Ordinary frequency is related to angular frequency by a factor of 2π. The period is the interval of time between events, so the period is the reciprocal of the frequency: T = 1/f.
Tracy Lauren Marrow, better known by his stage name Ice-T, is an American rapper and actor. He is active in both hip hop and heavy metal. Ice-T 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. The following year, he founded the record label Rhyme $yndicate Records and released another album, Power (1988), which would go platinum. He also released several other albums that went gold, including The Iceberg/Freedom of Speech... Just Watch What You Say! (1989), O.G. Original Gangster (1991) and Home Invasion (1993).
Mr. T is an American actor. 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, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time. In Albert Einstein's 1905 paper, On the Electrodynamics of Moving Bodies, the theory is presented as being based on just two postulates:
- The laws of physics are invariant (identical) in all inertial frames of reference. This is known as the principle of relativity.
- The speed of light in vacuum is the same for all observers, regardless of the motion of light source or observer. This is known as the principle of light constancy, or the principle of light speed invariance.
Thomas Stearns Eliot was a poet, essayist and playwright. He was a leading figure in English-language Modernist poetry where he reinvigorated the art through the use of language, writing style, and verse structure. He is also noted for his critical essays, which often re-evaluated long-held cultural beliefs.
Tyrannosaurus is a genus of large theropod dinosaur. The type species Tyrannosaurus rex, often shortened to T. rex or colloquially T-Rex, is one of the best represented theropods. It 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 latest Campanian-Maastrichtian ages of the late Cretaceous period, 72.7 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.
A magnetic field is a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. A permanent magnet's magnetic field pulls on ferromagnetic materials such as iron, and attracts or repels other magnets. In addition, a nonuniform magnetic field exerts minuscule forces on "nonmagnetic" materials by three other magnetic effects: paramagnetism, diamagnetism, and antiferromagnetism, although these forces are usually so small they can only be detected by laboratory equipment. Magnetic fields surround magnetized materials, electric currents, and electric fields varying in time. Since both strength and direction of a magnetic field may vary with location, it is described mathematically by a function assigning a vector to each point of space, called a vector field.
Thomas Edward Lawrence was a British Army officer, archaeologist, diplomat and writer known for his role during the Arab Revolt and Sinai and Palestine campaign against the Ottoman Empire in the First World War. The breadth and variety of his activities and associations, and Lawrence's ability to describe them vividly in writing, earned him international fame as Lawrence of Arabia, a title used for the 1962 film based on his wartime activities.
Newton's laws of motion are three physical laws that describe the relationship between the motion of an object and the forces acting on it. These laws, which provide the basis for Newtonian mechanics, can be paraphrased as follows:
- A body remains at rest, or in motion at a constant speed in a straight line, except insofar as it is acted upon by a force.
- At any instant of time, the net force on a body is equal to the rate at which the body's momentum is changing with time.
- If two bodies exert forces on each other, these forces have the same magnitude but opposite directions.
The Schrödinger equation is a partial differential equation that governs the wave function of a non-relativistic quantum-mechanical system. Its discovery was a significant landmark in the development of quantum mechanics. It is named after Erwin Schrödinger, an Austrian physicist, who postulated the equation in 1925 and published it in 1926, forming the basis for the work that resulted in his Nobel Prize in Physics in 1933.
Warner Media, LLC was an American multinational mass media and entertainment conglomerate owned by AT&T. It was headquartered at the 30 Hudson Yards complex in New York City.
The Black–Scholes or Black–Scholes–Merton model is a mathematical model for the dynamics of a financial market containing derivative investment instruments. From the parabolic partial differential equation in the model, known as the Black–Scholes equation, one can deduce the Black–Scholes formula, which gives a theoretical estimate of the price of European-style options and shows that the option has a unique price given the risk of the security and its expected return. The equation and model are named after economists Fischer Black and Myron Scholes. Robert C. Merton, who first wrote an academic paper on the subject, is sometimes also credited.
The Ford Model T is an automobile that was produced by the Ford Motor Company from October 1, 1908, to May 26, 1927. It is generally regarded as the first mass-affordable automobile, which made car travel available to middle-class Americans. The relatively low price was partly the result of Ford's efficient fabrication, including assembly line production instead of individual handcrafting. The savings from mass production allowed the price to decline from $780 in 1910 to $290 in 1924. It was mainly designed by three engineers, Joseph A. Galamb, Eugene Farkas, and Childe Harold Wills. The Model T was colloquially known as the "Tin Lizzie".
Phineas Taylor Barnum was an American showman, businessman, and politician remembered for promoting celebrated hoaxes and founding with James Anthony Bailey the Ringling Bros. and Barnum & Bailey Circus. He was also an author, publisher, and philanthropist, although he said of himself: "I am a showman by profession ... and all the gilding shall make nothing else of me." According to Barnum's critics, his personal aim was "to put money in his own coffers". The adage "there's a sucker born every minute" has frequently been attributed to him, although no evidence exists that he had coined the phrase.
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, beta, and gamma decay. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetic and nuclear forces.
Internet of things (IoT) describes devices with sensors, processing ability, software and other technologies that connect and exchange data with other devices and systems over the Internet or other communication networks. The Internet of things encompasses electronics, communication, and computer science engineering. "Internet of things" has been considered a misnomer because devices do not need to be connected to the public internet; they only need to be connected to a network and be individually addressable.
AT&T Inc., an abbreviation for its predecessor's former name, the American Telephone and Telegraph Company, is an American multinational telecommunications holding company headquartered at Whitacre Tower in Downtown Dallas, Texas. It is the world's third largest telecommunications company by revenue and the third largest wireless carrier in the United States behind Verizon and T-Mobile. As of 2023, AT&T was ranked 13th on the Fortune 500 rankings of the largest United States corporations, with revenues of $122.4 billion.
The kelvin is the base unit for temperature in the International System of Units (SI). The Kelvin scale is an absolute temperature scale that starts at the lowest possible temperature, taken to be 0 K. By definition, the Celsius scale and the Kelvin scale have the exact same magnitude; that is, a rise of 1 K is equal to a rise of 1 °C and vice versa, and any temperature in degrees Celsius can be converted to kelvin by adding 273.15.
Terminator 2: Judgment Day is a 1991 American science fiction action film directed by James Cameron, who co-wrote the script with William Wisher. Starring Arnold Schwarzenegger, Linda Hamilton, and Robert Patrick, it is the sequel to The Terminator (1984) and is the second installment in the Terminator franchise. In the film, the malevolent artificial intelligence Skynet sends a Terminator—a highly advanced killing machine—back in time to 1995 to kill the future leader of the human resistance John Connor when he is a child. The resistance sends back a less advanced, reprogrammed Terminator to protect Connor and ensure the future of humanity.
