Sharp

Sharp Corporation is a Japanese multinational corporation specializing in the manufacture and sale of telecommunications equipment, electric and electronic application equipment, and electronic components.^[1] Founded on September 15, 1912, by Tokuji Hayakawa in Matsui-cho, Honjo, Tokyo, the company initially operated as a small metalworking business producing innovative hardware items.^[1] The corporate name originates from Hayakawa's 1915 invention of the mechanical pencil, marketed as the "Ever-Ready Sharp Pencil," which gained popularity for its precise lead advancement mechanism and laid the foundation for Sharp's emphasis on precision engineering.^[1] Over the ensuing century, Sharp expanded into electronics, achieving milestones such as developing Japan's first microwave oven in 1961 and becoming the first to mass-produce it the following year, alongside the world's first all-transistor desktop calculator in 1964 and early advancements in liquid crystal display (LCD) technology.^[2] These innovations positioned Sharp as a leader in consumer and office electronics, including televisions, copiers, and solar cells, with headquarters now in Sakai-ku, Sakai City, Osaka Prefecture.^[1]^[3] Despite its technological contributions, Sharp encountered severe financial distress in the 2010s due to competitive pressures in the display panel market and unprofitable investments, culminating in its majority acquisition by Taiwan's Hon Hai Precision Industry Co., Ltd. (Foxconn) in 2016 for approximately $3.5 billion, which provided capital infusion but shifted control away from independent Japanese management.^[4]^[5] Under Foxconn's ownership, Sharp has focused on restructuring, emphasizing LCD production synergies and emerging technologies like IGZO displays, though it continues to navigate global market volatility as of 2025.^[1]

Etymology and primary definition

Origin and core meaning

The word "sharp" derives from Old English scearp, attested from before 1150, denoting something "having a cutting edge; pointed; intellectually acute, active, shrewd; keen (of senses); severe; biting, bitter (of tastes)."^[6]^[7] This Old English form traces to Proto-Germanic *skarpaz, which in turn stems from the Proto-Indo-European root *sker- meaning "to cut," reflecting an ancient conceptual link between sharpness and the physical act of incision or separation.^[6] Cognates appear in other Germanic languages, such as Old Norse skarpr and Old High German scarf, underscoring a shared Indo-European heritage focused on edged or pointed qualities.^[6] The core meaning of "sharp" as an adjective centers on adaptation for cutting or piercing, specifically "having a thin keen edge or fine point," which forms the basis for its primary literal usage in describing tools, weapons, or natural features capable of penetration or division.^[8] This foundational sense, evident in early texts for objects like knives or needles, extends metaphorically to sensory or cognitive acuity—such as keen eyesight, quick wits, or pungent flavors—due to the perceptual analogy of precision and intensity akin to a blade's action.^[8]^[9] Unlike bluntness, which implies diffusion or dullness, sharpness inherently connotes efficiency in boundary-making or delineation, a trait preserved across its semantic evolutions without dilution in the root concept.^[6]

Uses in arts and sciences

Music theory

In music theory, a sharp (♯) is an accidental symbol that raises the pitch of a note by one semitone, or half step, from its natural position on the diatonic scale.^[10]^[11] This alteration applies to the specific note it precedes, affecting all subsequent instances in the same measure unless canceled by a natural (♮) or another accidental.^[12] For example, a C sharp (C♯) sounds one semitone higher than C, equivalent to the pitch of D♭ in equal temperament tuning systems.^[13] Sharps appear both as individual accidentals within a composition and in key signatures to denote the tonal center of a piece.^[10] In major scales, the number of sharps determines the key: G major has one sharp (F♯), D major has two (F♯ and C♯), progressing through the circle of fifths up to seven sharps in C♯ major.^[13] This system facilitates modulation and harmonic structure, with the last sharp in a signature typically indicating the seventh scale degree, which resolves to the tonic.^[12] Enharmonically, sharps enable equivalent notations, such as F♯ and G♭, which sound identical on modern instruments but differ in theoretical context, particularly in non-tempered tunings or atonal music.^[11] The sharp symbol evolved from medieval notations, originally derived from the Latin durum (meaning "hard" or raised pitch), contrasting with the flat's molle (soft).^[14] By the 17th century, it standardized as the vertical hashtag-like ♯, replacing earlier diagonal forms, amid the development of barlines and mensural notation.^[15] Double sharps (♯♯) further raise a note by two semitones, used sparingly in keys like C major to notate raised scale degrees without altering letter names.^[10] These conventions underpin Western tonal music, influencing composition, performance, and analysis across genres from classical to jazz.^[13]

Optics and photography

In optics, sharpness refers to the precision with which an imaging system renders fine spatial details, characterized by high edge contrast and minimal blur from aberrations or diffraction. It combines resolution—the ability to separate closely adjacent features, often quantified in line pairs per millimeter (lp/mm)—with acutance, the perceptual enhancement from abrupt tonal transitions at boundaries.^[16]^[17] Quantitative evaluation of lens sharpness employs the Modulation Transfer Function (MTF), which plots contrast retention (modulation) against spatial frequency; values approaching 1.0 at low frequencies indicate excellent performance, while sustained high values at elevated frequencies (e.g., 30 lp/mm) denote superior detail reproduction. MTF charts distinguish sagittal and meridional measurements to reveal astigmatism, with industry benchmarks considering MTF above 0.6 (60%) as good and above 0.8 (80%) as excellent for critical applications.^[18]^[19]^[20] In photography, image sharpness depends on multiple interdependent factors, including lens design quality (mitigating spherical aberration and coma), aperture selection (optimal typically at f/5.6–f/11 to minimize diffraction while maximizing depth of field), and precise autofocus or manual focusing to align the plane of critical sharpness. Motion-induced blur from camera shake or subject movement is averted by shutter speeds exceeding the reciprocal of the focal length (e.g., 1/50 second for a 50 mm lens on full-frame sensors), while sensor pixel density and anti-aliasing filters further modulate effective resolution. Post-capture sharpening algorithms enhance perceived acutance but cannot recover lost resolution from optical limitations.^[21]^[22]^[23]

Mathematics and other sciences

In mathematics, the adjective "sharp" describes inequalities, bounds, or estimates that achieve the optimal constant, meaning equality holds for at least one non-trivial case, rendering further improvement impossible without altering the inequality's form.^[24]^[25] For example, the sharp quantitative isoperimetric inequality quantifies the deviation from equality in the classical isoperimetric problem, relating a set's perimeter and enclosed volume in Euclidean space with precise error terms.^[26] Similarly, sharp constants appear in interpolation inequalities for discrete operators, such as those bounding norms in finite-dimensional spaces.^[27] In optimization, weak sharp minima extend the concept of strongly unique minima to non-unique solution sets, where the objective function exhibits linear growth away from the minimizer set, characterized by a positive modulus of continuity.^[28] Sharp thresholds also arise in probabilistic combinatorics and random graph theory, marking abrupt transitions in properties like connectivity as parameters vary.^[29] In quantum mechanics, sharp measurements refer to ideal observables yielding precise, definite outcomes upon projection onto eigenspaces, assuming no inherent apparatus uncertainty, in contrast to unsharp measurements that average over distributions of sharp events.^[30] In statistical physics, sharp thresholds describe phase transitions where macroscopic properties change discontinuously, often modeled via Boolean functions or percolation, with applications to models like the Ising ferromagnet.^[31] Sharp interfaces in computational physics preserve discontinuities in simulations of multiphase flows or front propagation, enabling accurate tracking of boundaries without diffusive smoothing.^[32]

Individuals

People with the surname Sharp

Granville Sharp (10 November 1735 – 6 July 1813) was an English abolitionist and scholar who became one of the earliest campaigners against the British slave trade after encountering an enslaved African in 1765, leading him to advocate for legal recognition of slaves' freedom on English soil.^[47] His 1772 Somerset case victory established a precedent that slaves could not be forcibly removed from England, influencing abolitionist efforts and the founding of the Sierra Leone Company in 1787 to resettle freed slaves.^[48] Sharp also contributed to biblical scholarship and music, publishing works on Greek grammar and founding a committee for African instruction in 1787.^[49] Cecil Sharp (22 November 1859 – 23 June 1924) was an English folklorist and music educator who collected and preserved over 3,000 English folk songs and dances between 1903 and 1924, establishing them as core elements of national cultural heritage. His fieldwork in rural England and Appalachia documented traditions threatened by industrialization, and he co-founded the English Folk Dance Society in 1911, which evolved into the English Folk Dance and Song Society. Sharp's advocacy emphasized folk music's role in education, influencing school curricula and the revival of Morris dancing.^[50] Phillip Allen Sharp (born 6 June 1944) is an American molecular biologist awarded the 1993 Nobel Prize in Physiology or Medicine, shared with Richard J. Roberts, for discovering split genes and RNA splicing in eukaryotes, revealing that genes consist of exons and introns rather than continuous sequences. This breakthrough, made at Cold Spring Harbor Laboratory in 1977 using adenovirus RNA, transformed understanding of gene expression and eukaryotic genome structure, enabling advances in molecular biology and biotechnology. Sharp later directed MIT's Center for Cancer Research from 1985 to 1991 and co-founded Biogen.^[51]^[52] Gene Sharp (21 January 1928 – 28 January 2018) was an American political scientist and nonviolence theorist whose 1973 book The Politics of Nonviolent Action outlined 198 methods of nonviolent resistance, influencing global movements including the Velvet Revolution, Arab Spring, and color revolutions. His works, emphasizing strategic civilian-based defense over armed conflict, were translated into over 40 languages and used by dissidents against authoritarian regimes, though critics noted potential for manipulation by external actors. Sharp founded the Albert Einstein Institution in 1983 to promote nonviolent struggle research.^[50] Other individuals include Keesha Sharp (born 1973), an American actress known for roles in The Larry Sanders Show and Girlfriends, and Alex Sharp (born 1988), a British actor nominated for a Tony Award for The Curious Incident of the Dog in the Night-Time in 2015.^[53]

Geographical locations

Antarctica

Sharp Glacier is a glacier located in Graham Land on the Antarctic Peninsula, flowing northward to the head of Lallemand Fjord and situated immediately east of the Boyle Mountains.^[59] The glacier's coordinates are approximately 67°21′54″S 66°26′21″W.^[60] It forms part of the glaciated terrain characteristic of the region, where outlet glaciers descend from the interior ice plateau toward the western coast amid fjords and mountain ranges.^[59] The feature was mapped by the Falkland Islands Dependencies Survey (FIDS), which conducted ground surveys and aerial photography between 1948 and 1959 to delineate coastal and glacial boundaries in Graham Land.^[59] This mapping effort contributed to the British Antarctic Territory gazetteer, documenting Sharp Glacier as a distinct outlet alongside neighboring features such as Haefeli Glacier and Finsterwalder Glacier, whose termini converge near the fjord entrance.^[61] Graham Land's glaciers, including Sharp, are influenced by the region's maritime climate, with flow dynamics affected by calving into Lallemand Fjord and broader ice sheet interactions.^[62]

United States

Sharp County is a county in northern Arkansas encompassing approximately 604 square miles of rolling hills, forests, and rivers. Established on August 12, 1868, from parts of Izard, Jackson, and Lawrence counties, it was named after early settler Ephraim Sharp, who operated a popular ferry on the Spring River.^[63] The county seat is Ash Flat, with other incorporated municipalities including Hardy, Cherokee Village, Cave City, and Highland. As of the 2020 United States census, the population totaled 17,271 residents, reflecting a rural economy historically centered on timber harvesting, agriculture, and hunting, supplemented by tourism to sites like the Spring River for fishing and canoeing, and Crystal River Cave for spelunking.^[64] ^[63] Beyond the county, smaller settlements bear the name. In Milam County, Texas, Sharp is a rural unincorporated community on Farm Road 487, situated twelve miles northwest of Rockdale; it developed around a Presbyterian church founded in the 1870s amid fertile black soil attractive to post-Civil War settlers for farming and ranching.^[65] These locations, along with minor features like Sharp Lake in Jackson County, Michigan—a small reservoir supporting local recreation—illustrate the dispersed application of the name across U.S. topography, often tied to historical settlement patterns rather than unified geographic traits.^[66]

Outer space

Mount Sharp, also known as Aeolis Mons, is the central mound within Gale crater on Mars, a impact feature measuring 154 kilometers in diameter. The mountain rises about 5.5 kilometers above the crater floor and exhibits stratified layers of sedimentary rock that preserve evidence of ancient fluvial and lacustrine environments, including minerals formed in the presence of liquid water. NASA's Curiosity rover landed in Gale crater on August 5, 2012, and has since traversed the mountain's base, analyzing sulfate-rich layers and organic molecules that suggest periods of habitability extending from the Noachian to Hesperian epochs. As of 2025, the rover continues ascending Mount Sharp, providing data on Mars' climatic evolution through orbital and in-situ spectroscopy.^[67]^[68] On the Moon, Sharp is an impact crater situated west of Sinus Iridum in the Mare Imbrium basin, characterized by a rugged rim and interior consistent with typical lunar highland craters formed by meteoroid impacts. During Apollo 12's second extravehicular activity on November 19, 1969, astronauts Charles Conrad and Alan L. Bean traversed approximately 1.3 kilometers to the crater's rim, conducting visual inspections, photography, and contingency sample collections to assess its geological context amid surrounding mare basalts. The visit, lasting from about 1+23 to 1+51 into the EVA, contributed to early understandings of lunar regolith distribution and impact gardening processes.^[69] Rima Sharp is a sinuous rille in Oceanus Procellarum, extending roughly 320 kilometers and ranking among the longest volcanic channels on the lunar surface, formed by effusive lava flows during the Imbrian period. Located less than 20 kilometers from the Chang'e-5 landing site, it served as a probable source for the mission's returned basaltic samples, which crater counting and isotopic analysis date to approximately 1.2 billion years ago, indicating prolonged mare volcanism. The rille's morphology, including meanders and levees, reflects low-viscosity lava dynamics under reduced gravity, with cross-cutting relations to nearby craters constraining its emplacement timeline.^[70]

Other uses

Titles

The surname Sharp features in two distinct baronetcies within the British honours system, both hereditary titles ranking below barons but above knights. The Sharp Baronetcy of Scotscraig, in the County of Fife, traces to William Sharp (died 1704), a merchant of St Andrews, who was the first holder.^[98] His successors included Sir Alexander Sharp (died 1769), the fifth baronet, whose lineage merged with the Bethune family through marriage, leading to its designation as the Bethune, formerly Sharp, baronetcy.^[99] Genealogical records confirm intermediate holders such as James Sharp (1710–1766), the third baronet.^[100] The Sharp Baronetcy of Warden Court, Maidstone, in Kent, was held by Edward Sharp (1854–1931), a preserves manufacturer and founder of Edward Sharp & Sons Limited.^[101] His son, Herbert Edward Sharp, succeeded as the second baronet upon his father's death in 1931 and served as a director of the family firm.^[101] The title became extinct following the death of the second baronet, with no further heirs recorded in peerage compilations.^[101] No higher peerages, such as earldoms or viscountcies, have been associated with the surname Sharp in British nobility records.

Miscellaneous concepts

In music theory, the sharp symbol (♯) denotes an accidental that raises the pitch of a note by one semitone (half step), altering its position relative to the natural notes on the chromatic scale.^[13] This modification applies to individual notes or, when placed in a key signature, to all occurrences of that note within a composition, facilitating modulation and scale construction; for instance, F♯ is the note one semitone above F.^[102] Sharps originated in medieval notation systems to expand the diatonic scale, with their use standardized by the 16th century in equal temperament tuning, where the semitone interval equals 100 cents logarithmically.^[103] In mathematics, particularly in analysis and inequalities, a "sharp" bound or constant describes the optimal value in an inequality where equality holds for some non-trivial case, distinguishing it from looser approximations.^[25] For example, in the inequality | \sin x | \leq |x| for real x, the constant 1 is sharp because equality occurs at x=0.^[104] This concept ensures theorems achieve maximal precision, as weakening the bound would violate the equality case, and it appears in fields like optimization and functional analysis, where weak sharp minima extend uniqueness to non-singleton solution sets with linear growth rates away from optima.^[28] In philosophy of language and logic, sharpness refers to the requirement, emphasized by Gottlob Frege, that concepts and terms possess determinate, objectively truth-evaluable extensions without vagueness or gaps.^[105] A sharp concept divides objects into those falling under it and those not, enabling bivalent truth values; Frege argued this sharpness underpins logical rigor, critiquing natural language for often lacking it, which leads to sorites paradoxes or indeterminate boundaries.^[106] This ideal influences formal semantics, where predicates must yield precise denotations, though critics note it may overidealize ordinary discourse by demanding total definability.^[106]
