Blue–green Distinction In Language
In many languages, the colors described in English as "blue" and "green" are colexified, i.e. expressed using a single cover term. To describe this English lexical gap, linguists use the portmanteau word ''grue'', from ''green'' and ''blue'', a term coined by the philosopher Nelson Goodman—with a rather different meaning—in his 1955 ''Fact, Fiction, and Forecast'' to illustrate his "new riddle of induction". The exact definition of "blue" and "green" may be complicated by the speakers not primarily distinguishing the hue, but using terms that describe other color components such as saturation and luminosity, or other properties of the object being described. For example, "blue" and "green" might be distinguished, but a single term might be used for both if the color is dark. Furthermore, green might be associated with yellow, and blue with either black or gray. According to Brent Berlin and Paul Kay's 1969 study '' Basic Color Terms: Their Universality and Evolution'', d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linear Visible Spectrum
Linearity is the property of a mathematical relationship (''function'') that can be graphically represented as a straight line. Linearity is closely related to '' proportionality''. Examples in physics include rectilinear motion, the linear relationship of voltage and current in an electrical conductor ( Ohm's law), and the relationship of mass and weight. By contrast, more complicated relationships are ''nonlinear''. Generalized for functions in more than one dimension, linearity means the property of a function of being compatible with addition and scaling, also known as the superposition principle. The word linear comes from Latin ''linearis'', "pertaining to or resembling a line". In mathematics In mathematics, a linear map or linear function ''f''(''x'') is a function that satisfies the two properties: * Additivity: . * Homogeneity of degree 1: for all α. These properties are known as the superposition principle. In this definition, ''x'' is not necessarily a rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light
Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization. Its speed in a vacuum, 299 792 458 metres a second (m/s), is one of the fundamental constants of nature. Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and par ...

Wadjet
Wadjet (; egy, wꜢḏyt "Green One"), known to the Greek world as Uto (; grc-koi, Οὐτώ) or Buto (; ) among other renderings including Wedjat, Uadjet, and Udjo, was originally the ancient local goddess of the city of Dep. It became part of the city that the Egyptians named Per-Wadjet ("House of Wadjet") and the Greeks called Buto (now Desouk), which was an important site in prehistoric Egypt and the cultural developments of the Paleolithic. There was also a Per-Wadjet in Upper Egypt. Wadjet was said to be the matron and protector of Lower Egypt, and upon unification with Upper Egypt, the joint protector and patron of all of Egypt. The image of Wadjet with the sun disk is called the uraeus, and it was the emblem on the crown of the rulers of Lower Egypt. She was also the protector of kings and of women in childbirth. Wadjet was said to be the nurse of the infant god Horus. With the help of his mother Isis, they protected Horus from his treacherous uncle, Set, when they to ...

Egyptian Language
The Egyptian language or Ancient Egyptian ( ) is a dead language, dead Afroasiatic languages, Afro-Asiatic language that was spoken in ancient Egypt. It is known today from a large Text corpus, corpus of surviving texts which were made accessible to the modern world following the decipherment of ancient Egyptian scripts, decipherment of the ancient Egyptian scripts in the early 19th century. Egyptian is one of the List of languages by first written accounts, earliest written languages, first being recorded in the Egyptian hieroglyphs, hieroglyphic script in the late 4th millennium BC. It is also the longest-attested human language, with a written record spanning over 4000 years. Its classical language, classical form is known as Middle Egyptian, the vernacular of the Middle Kingdom of Egypt which remained the literary language of Egypt until the Egypt (Roman province), Roman period. By the time of classical antiquity the spoken language had evolved into Demotic (Egyptian), Dem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanosis
Cyanosis is the change of body tissue color to a bluish-purple hue as a result of having decreased amounts of oxygen bound to the hemoglobin in the red blood cells of the capillary bed. Body tissues that show cyanosis are usually in locations where the skin is thinner, including the mucous membranes, lips, nail beds, and ear lobes. Some medications containing amiodarone or silver, Mongolian spots, large birth marks, and the consumption of food products with blue or purple dyes can also result in the bluish skin tissue discoloration and may be mistaken for cyanosis. Cyanosis is further classified into central cyanosis vs. peripheral cyanosis. Pathophysiology The mechanism behind cyanosis is different depending on whether it is central or peripheral. Central cyanosis Central cyanosis is caused by a decrease in arterial oxygen saturation (SaO2) and begins to show once the concentration of deoxyhemoglobin in the blood reaches a concentration of ≥ 5.0 g/dL (≥ 3.1 mmol/L ...

Moroccan Arabic
Moroccan Arabic ( ar, العربية المغربية الدارجة, translit=al-ʻArabīya al-Maghribīya ad-Dārija ), also known as Darija (), is the dialectal, vernacular form or forms of Arabic spoken in Morocco. It is part of the Maghrebi Arabic dialect continuum and as such is mutually intelligible to some extent with Algerian Arabic and to a lesser extent with Tunisian Arabic. It is spoken by 92% of the population of Morocco. While Modern Standard Arabic is used to varying degrees in formal situations such as religious sermons, books, newspapers, government communications, news broadcasts and political talk shows, Moroccan Arabic is the predominant spoken language of the country and has a strong presence in Moroccan television entertainment, cinema and commercial advertising. Moroccan Arabic has many regional dialects and accents as well. Its mainstream dialect is the one used in Casablanca, Rabat and Fez, and therefore it dominates the media, eclipsing the other regional ...

Arabic Language
Arabic (, ' ; , ' or ) is a Semitic language spoken primarily across the Arab world.Semitic languages: an international handbook / edited by Stefan Weninger; in collaboration with Geoffrey Khan, Michael P. Streck, Janet C. E.Watson; Walter de Gruyter GmbH & Co. KG, Berlin/Boston, 2011. 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. Since the 7th century, Arabic has been characterized by diglossia, with an opposition between a standard prestige language—i.e., Literary Arabic: Modern Standard Arabic (MSA) or Classical Arabic—and diverse vernacular varieties, which serve as mother tongues. Colloquial dialects vary significantly from MSA, impeding mutual intelligibility. MSA is only acquired through formal education and is not spoken natively. It is the language of literature, official documents, and formal written m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kabyle Language
Kabyle () or Kabylian (; native name: ''Taqbaylit'' , ) is a Berber language spoken by the Kabyle people in the north and northeast of Algeria. It is spoken primarily in Kabylia, east of the capital Algiers and in Algiers itself, but also by various groups near Blida, such as the Beni Salah and Beni Bou Yaqob.(extinct?) Estimating the number of Berber speakers is very difficult and figures are often contested. Estimates of the number of Kabyle speakers globally range from three million in 2003 according to the '' International Encyclopedia of Linguistics'' and three million in 2015 in Algeria only to six to seven million worldwide in 2020 according to Asya Pereltsvaig and ''Ethnologue''. Kabyle has a significant Arabic, French, Latin, Greek, Phoenician and Punic substratum, and Arabic loanwords represent 35% of the total Kabyle vocabulary. Classification Kabyle is one of the Berber languages, a family within the Afroasiatic languages. It is believed to have broken off very e ...

Shilha Language
, now more usually known as Tashelhit , is a Berber language spoken in southwestern Morocco. The endonym is , and in recent English publications the name of the language is often rendered ''Tashelhit'', ''Tashelhiyt'' or ''Tashlhiyt''. In Moroccan Arabic the language is called , from which the English name ''Shilha'' is derived. When referring to the language, anthropologists and historians prefer the name "Shilha", which is in the Oxford English Dictionary (OED). Linguists writing in English prefer "Tashelhit" (or a variant spelling). In French sources the language is called , or . Shilha is spoken in an area covering c. 100,000 square kilometres, making the language area approximately the size of Iceland, or the US state of Kentucky. The area comprises the western part of the High Atlas mountains and the regions to the south up to the Draa River, including the Anti-Atlas and the alluvial basin of the Souss River.
