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 umbrella term. To render this ambiguous notion in English, linguists use the blend word ''grue'', from ''green'' and ''blue'', a term coined by the philosopher Nelson Goodmanwith an unrelated meaningin 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'', disti ...

Linear Visible Spectrum
In mathematics, the term ''linear'' is used in two distinct senses for two different properties: * linearity of a '' function'' (or '' mapping''); * linearity of a ''polynomial''. An example of a linear function is the function defined by f(x)=(ax,bx) that maps the real line to a line in the Euclidean plane R2 that passes through the origin. An example of a linear polynomial in the variables X, Y and Z is aX+bY+cZ+d. Linearity of a mapping is closely related to '' proportionality''. Examples in physics include 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, such as between velocity and kinetic energy, 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. Linearity of a polynomial means that its degree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Light
Light, visible light, or visible radiation is electromagnetic radiation that can be visual perception, perceived by the human eye. Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequency, frequencies of 750–420 terahertz (unit), terahertz. The visible band sits adjacent to the infrared (with longer wavelengths and lower frequencies) and the ultraviolet (with shorter wavelengths and higher frequencies), called collectively ''optical radiation''. 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 (physics), intensity, propagation direction, frequency or wavelength spectrum, and polarization (waves), polarization. Its speed of light, speed in vacuum, , is one of the fundamental physi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Wadjet
Wadjet (; "Green One"), known to the Greek world as Uto (; ) or Buto (; ) among other renderings including Wedjat, Uadjet, and Udjo, was originally the ancient Egyptian Tutelary deity, local goddess of the city of Dep or Buto in Lower Egypt, which was an important site in prehistoric Egypt. Wadjet's worship originally started in the Predynastic period, but evolved over time from a local goddess to a patron goddess. Wadjet was closely associated in ancient Egyptian religion with the Eye of Ra and the Eye of Horus symbols, each powerful protective deities.Wilksinson, Richard H. (2003) ''The Complete Gods and Goddesses of Ancient Egypt''. Thames & Hudson. p. 227 The hieroglyph for her eye is shown below; sometimes two are shown in the sky of religious images. There is little consensus on which eye is truly tied to Wadjet as both have some importance to her. The main differences between her eyes are which side of the face they are on, left or right. The color of these eyes in amul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Egyptian Language
The Egyptian language, or Ancient Egyptian (; ), is an extinct branch of the Afro-Asiatic languages that was spoken in ancient Egypt. It is known today from a large corpus of surviving texts, which were made accessible to the modern world following the decipherment of the ancient Egyptian scripts in the early 19th century. Egyptian is one of the earliest known written languages, first recorded in the hieroglyphic script in the late 4th millennium BC. It is also the longest-attested human language, with a written record spanning over 4,000 years. Its classical form, known as " Middle Egyptian," served as the vernacular of the Middle Kingdom of Egypt and remained the literary language of Egypt until the Roman period. By the time of classical antiquity, the spoken language had evolved into Demotic, and by the Roman era, diversified into various Coptic dialects. These were eventually supplanted by Arabic after the Muslim conquest of Egypt, although Bohairic Coptic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Cyanosis
Cyanosis is the change of Tissue (biology), tissue color to a bluish-purple hue, as a result of decrease in the amount of oxygen bound to the hemoglobin in the red blood cells of the capillary bed. Cyanosis is apparent usually in the Tissue (biology), body tissues covered with thin skin, including the mucous membranes, lips, nail beds, and ear lobes. Some medications may cause discoloration such as medications containing amiodarone or silver. Furthermore, mongolian spots, large birthmarks, 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. Appropriate physical examination and history taking is a crucial part to diagnose cyanosis. Management of cyanosis involves treating the main cause, as cyanosis is not a disease, but rather a symptom. Cyanosis is further classified into central cyanosis and peripheral cyanosis. Pathophysiology The mechanism behind cyanosis is different dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Moroccan Arabic
Moroccan Arabic ( ), also known as Darija ( or ), 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 90.9% 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, with its mainstream dialect being the one used in Casablanca, Rabat, Meknes and Fez, and therefore it dominates the media and eclipses most of the other regional accents.

Arabic Language
Arabic (, , or , ) is a Central Semitic languages, Central Semitic language of the Afroasiatic languages, Afroasiatic language family spoken primarily in the Arab world. The International Organization for Standardization (ISO) assigns language codes to 32 varieties of Arabic, including its standard form of Literary Arabic, known as Modern Standard Arabic, which is derived from Classical Arabic. This distinction exists primarily among Western linguists; Arabic speakers themselves generally do not distinguish between Modern Standard Arabic and Classical Arabic, but rather refer to both as ( "the eloquent Arabic") or simply ' (). Arabic is the List of languages by the number of countries in which they are recognized as an official language, third most widespread official language after English and French, one of six official languages of the United Nations, and the Sacred language, liturgical language of Islam.

Kabyle Language
Kabyle () or Kabylian (; native name: ''Taqbaylit'' ) is a Berber languages, Berber language spoken by the Kabyle people in the north and northeast of Algeria. It is spoken primarily in Kabylia Estimating the number of Berber speakers is very difficult and figures are often contested. A 2004 estimate was that 9.4% of the Algerian population spoke Kabyle. The number of diaspora speakers has been estimated at one million. Classification Kabyle is one of the Northern Berber languages, a branch of the Berber languages, Berber language family within Afroasiatic languages, Afroasiatic. It is believed to have broken off very early from proto-Berber language, Proto-Berber, although after the Zenaga language did so. According to Maarten Kossmann, Kossmann (2020), Kabyle appears to be quite distinct. In several respects, it shares certain linguistic innovations with the Atlas languages, western Moroccan dialect group. However, it is unclear whether these similarities result from an earl ...

Shilha Language
( ; from its name in Moroccan Arabic, ), now more commonly known as Tashelhiyt or Tachelhit ( ; from the endonym , ), is a Berber language spoken in southwestern Morocco. 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 around 100,000 square kilometres. 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 Sous River. The largest urban centres in the area are the coastal city of Agadir (population over 400,000) and the towns of Guelmim, Taroudant, Oulad Teima, Tiznit and Ouarzazate.Adnor, Abdellah (2004).

Amazigh
Berbers, or the Berber peoples, also known as Amazigh or Imazighen, are a diverse grouping of distinct ethnic groups indigenous to North Africa who predate the arrival of Arabs in the Maghreb. Their main connections are identified by their usage of Berber languages, most of them mutually unintelligible, which are part of the Afroasiatic language family. They are indigenous to the Maghreb region of North Africa, where they live in scattered communities across parts of Morocco, Algeria, Libya, and to a lesser extent Tunisia, Mauritania, northern Mali and northern Niger. Smaller Berber communities are also found in Burkina Faso and Egypt's Siwa Oasis. Descended from Stone Age tribes of North Africa, accounts of the Imazighen were first mentioned in Ancient Egyptian writings. From about 2000 BC, Berber languages spread westward from the Nile Valley across the northern Sahara into the Maghreb. A series of Berber peoples such as the Mauri, Masaesyli, Massyli, Musulamii, ...

Amazigh Language
The Berber languages, also known as the Amazigh languages or Tamazight, are a branch of the Afroasiatic language family. They comprise a group of closely related but mostly mutually unintelligible languages spoken by Berber communities, who are indigenous to North Africa.Hayward, Richard J., chapter ''Afroasiatic'' in Heine, Bernd & Nurse, Derek, editors, ''African Languages: An Introduction'' Cambridge 2000. . The languages are primarily spoken and not typically written. Historically, they have been written with the ancient Libyco-Berber script, which now exists in the form of Tifinagh. Today, they may also be written in the Berber Latin alphabet or the Arabic script, with Latin being the most pervasive. The Berber languages have a similar level of variety to the Romance languages, although they are sometimes referred to as a single collective language, often as "Berber", "Tamazight", or "Amazigh". The languages, with a few exceptions, form a dialect continuum. There is a de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
