In music theory, a diatonic scale is any heptatonic scale that includes five whole steps and two half steps (semitones) in each octave, in which the two half steps are separated from each other by either two or three whole steps, depending on their position in the scale. This pattern ensures that, in a diatonic scale spanning more than one octave, all the half steps are maximally separated from each other.
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides. The gravitational attraction of the original gaseous matter present in the Universe caused it to begin coalescing and forming stars and caused the stars to group together into galaxies, so gravity is responsible for many of the large-scale structures in the Universe. Gravity has an infinite range, although its effects become increasingly weaker as objects get further away.
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 Standard Model of particle physics is the theory describing three of the four known fundamental forces in the universe, as well as classifying all known elementary particles. It was developed in stages throughout the latter half of the 20th century, through the work of many scientists around the world, with the current formulation being finalized in the mid-1970s upon experimental confirmation of the existence of quarks. Since then, confirmation of the top quark (1995), the tau neutrino (2000), and the Higgs boson (2012) have added further credence to the Standard Model. In addition, the Standard Model has predicted various properties of weak neutral currents and the W and Z bosons with great accuracy.
Ecchi is an often used slang term in the Japanese language for playfully sexual actions. As an adjective, it is used with the meaning of "sexy", "dirty" or "naughty"; as a verb, ecchi suru means “to have sex” or, as a noun, to describe someone of lascivious behavior. It is perhaps softer than the Japanese word ero, and does not imply perversion in the way hentai does.
Christopher George Latore Wallace, better known by his stage names the Notorious B.I.G., Biggie Smalls, or simply Biggie, was an American rapper and songwriter. Rooted in the New York rap scene and gangsta rap traditions, he is considered one of the greatest rappers of all time. The Notorious B.I.G. became known for his distinctive laidback lyrical delivery, offsetting the lyrics' often grim content and his own intimidating appearance. His music was often semi-autobiographical, telling of hardship and criminality, but also of debauchery and celebration.
The peregrine falcon, also known as the peregrine, and historically as the duck hawk in North America, is a widespread bird of prey (raptor) in the family Falconidae. A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed, reaching over 320 km/h (200 mph) during its characteristic hunting stoop, making it the fastest bird in the world, as well as the fastest member of the animal kingdom. According to a National Geographic TV program, the highest measured speed of a peregrine falcon is 389 km/h (242 mph). As is typical for bird-eating raptors, peregrine falcons are sexually dimorphic, with females being considerably larger than males.
A G-string is a type of thong, a narrow piece of fabric, leather, or satin that covers or holds the genitals, passes between the buttocks, and is attached to a waistband around the hips. A G-string can be worn both by men and by women. It may also be worn in swimwear, where it may serve as a bikini bottom, but may be worn alone as a monokini or topless swimsuit. G-strings may also be worn by exotic or go-go dancers. As underwear, a G-string may be worn in preference to panties to avoid creation of a visible panty line, or to briefs in order to enhance sex-appeal.
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon.
Uppaluri Gopala Krishnamurti, better known as U.G., was an Indian speaker who questioned the state of enlightenment. Although many considered him an "enlightened" person, U.G. often referred to his state of being as the "natural state". He claimed that the return to the natural state is a rare, acausal, biological occurrence, which he referred to in his own life as “the calamity”. Because of this, he forbade people from pursuing it as a spiritual goal and urged them to just learn to live under the stranglehold of thought and self-consciousness.
Medical Subject Headings (MeSH) is a comprehensive controlled vocabulary for the purpose of indexing journal articles and books in the life sciences. It serves as a thesaurus that facilitates searching. Created and updated by the United States National Library of Medicine (NLM), it is used by the MEDLINE/PubMed article database and by NLM's catalog of book holdings. MeSH is also used by ClinicalTrials.gov registry to classify which diseases are studied by trials registered in ClinicalTrials.
The following is a defined list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple or compound. The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article.
In mathematics, a differential equation is an equation that relates one or more functions and their derivatives. In applications, the functions generally represent physical quantities, the derivatives represent their rates of change, and the differential equation defines a relationship between the two. Such relations are common; therefore, differential equations play a prominent role in many disciplines including engineering, physics, economics, and biology.
G.I. are initials used to describe the soldiers of the United States Army and airmen of the United States Air Forces and also for general items of their equipment. The term G.I. has been used as an initialism of "Government Issue", "General Issue", or "Ground Infantry", but it originally referred to "galvanized iron", as used by the logistics services of the United States Armed Forces.
In the context of an internal combustion engine, the term stroke has the following related meanings
2C-G is a psychedelic phenethylamine of the 2C family. First synthesized by Alexander Shulgin, it is sometimes used as an entheogen. It has structural and pharmacodynamic properties similar to 2C-D and Ganesha. Like many of the phenethylamines in PiHKAL, 2C-G and its homologs have only been taken by Shulgin and a small test group, making it difficult to ensure completeness when describing effects.
The Heteroceridae, or variegated mud-loving beetles, are a widespread and relatively common family of beetles. They occur on every continent except for Antarctica.
In heraldry and heraldic vexillology, a blazon is a formal description of a coat of arms, flag or similar emblem, from which the reader can reconstruct the appropriate image. The verb to blazon means to create such a description. The visual depiction of a coat of arms or flag has traditionally had considerable latitude in design, but a verbal blazon specifies the essentially distinctive elements. A coat of arms or flag is therefore primarily defined not by a picture but rather by the wording of its blazon. Blazon is also the specialized language in which a blazon is written, and, as a verb, the act of writing such a description. Blazonry is the art, craft or practice of creating a blazon. The language employed in blazonry has its own vocabulary, grammar and syntax, which becomes essential for comprehension when blazoning a complex coat of arms.
Grevillea victoriae, also known as royal grevillea or mountain grevillea, is a shrub which is endemic to south-eastern New South Wales and mountainous parts of Victoria in Australia.
