Ancient Egyptian Pottery
Ancient Egyptian pottery includes all objects of fired clay from ancient Egypt. First and foremost, ceramics served as household wares for the storage, preparation, transport, and consumption of food, drink, and raw materials. Such items include beer and wine mugs and water jugs, but also bread moulds, fire pits, lamps, and stands for holding round vessels, which were all commonly used in the Egyptian household. Other types of pottery served ritual purposes. Ceramics are often found as grave goods. Specialists in ancient Egyptian pottery draw a fundamental distinction between ceramics made of Nile clay and those made of marl clay, based on chemical and mineralogical composition and ceramic properties. Nile clay is the result of eroded material in the Ethiopian mountains, which was transported into Egypt by the Nile. This clay has deposited on the banks of the Nile in Egypt since the Late Pleistocene by the flooding of the Nile. Marl clay is a yellow-white stone which occurs in li ...

Eighteenth Dynasty Of Egypt
The Eighteenth Dynasty of Egypt (notated Dynasty XVIII, alternatively 18th Dynasty or Dynasty 18) is classified as the first dynasty of the New Kingdom of Egypt, the era in which ancient Egypt achieved the peak of its power. The Eighteenth Dynasty spanned the period from 1550/1549 to 1292 BC. This dynasty is also known as the Thutmoside Dynasty for the four pharaohs named Thutmose. Several of Egypt's most famous pharaohs were from the Eighteenth Dynasty, including Tutankhamun. Other famous pharaohs of the dynasty include Hatshepsut (c. 1479 BC–1458 BC), the longest-reigning woman pharaoh of an indigenous dynasty, and Akhenaten (c. 1353–1336 BC), the "heretic pharaoh", with his Great Royal Wife, Nefertiti. The Eighteenth Dynasty is unique among Egyptian dynasties in that it had two Queen regnant, queens regnant, women who ruled as sole pharaoh: Hatshepsut and Neferneferuaten, usually identified as Nefertiti. History Early Dynasty XVIII Dynasty XVIII was founded by Ahmo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classification
Classification is the activity of assigning objects to some pre-existing classes or categories. This is distinct from the task of establishing the classes themselves (for example through cluster analysis). Examples include diagnostic tests, identifying spam emails and deciding whether to give someone a driving license. As well as 'category', synonyms or near-synonyms for 'class' include 'type', 'species', 'order', 'concept', 'taxon', 'group', 'identification' and 'division'. The meaning of the word 'classification' (and its synonyms) may take on one of several related meanings. It may encompass both classification and the creation of classes, as for example in 'the task of categorizing pages in Wikipedia'; this overall activity is listed under taxonomy. It may refer exclusively to the underlying scheme of classes (which otherwise may be called a taxonomy). Or it may refer to the label given to an object by the classifier. Classification is a part of many different kinds of activ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silicon
Silicon is a chemical element; it has symbol Si and atomic number 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid (sometimes considered a non-metal) and semiconductor. It is a member of group 14 in the periodic table: carbon is above it; and germanium, tin, lead, and flerovium are below it. It is relatively unreactive. Silicon is a significant element that is essential for several physiological and metabolic processes in plants. Silicon is widely regarded as the predominant semiconductor material due to its versatile applications in various electrical devices such as transistors, solar cells, integrated circuits, and others. These may be due to its significant band gap, expansive optical transmission range, extensive absorption spectrum, surface roughening, and effective anti-reflection coating. Because of its high chemical affinity for oxygen, it was not until 1823 that Jöns Jakob Berzelius was first able to p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nile Flood
The flooding of the Nile (commonly referred to as ''the Inundation'') and its silt deposition was a natural cycle first attested in Ancient Egypt. It was of singular importance in the history and culture of Egypt. Governments and administrators of Egypt began constructing infrastructure to control the flooding in the 19th century, and these projects continued into the 20th. The annual flooding cycle in Egypt came to an end in 1970 with the completion of the Aswan High Dam. The river's predictability and annual deposits in the Nile Valley and Delta made for extraordinarily rich soil—classified today as alluvium on a bed of entisol— enabling the Egyptians to build an empire on the basis of its enormous agricultural wealth and surpluses of cereals which could be stored or traded. Egyptians were one of the first groups of people to practice agriculture on a large scale. This in turn was only possible with their innovation of surface irrigation, also called "basin irrigation", w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RPM Ägypten 127
Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or r⋅min−1) is a unit of rotational speed (or rotational frequency) for rotating machines. One revolution per minute is equivalent to hertz. Standards ISO 80000-3:2019 defines a physical quantity called ''rotation'' (or ''number of revolutions''), dimensionless, whose instantaneous rate of change is called ''rotational frequency'' (or ''rate of rotation''), with units of reciprocal seconds (s−1). A related but distinct quantity for describing rotation is ''angular frequency'' (or ''angular speed'', the magnitude of angular velocity), for which the SI unit is the radian per second (rad/s). Although they have the same dimensions (reciprocal time) and base unit (s−1), the hertz (Hz) and radians per second (rad/s) are special names used to express two different but proportional ISQ quantities: frequency and angular frequency, respectively. The conversions between a frequency and an angular frequency are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egyptian Archaeology
Egyptology (from ''Egypt'' and Greek , ''-logia''; ) is the scientific study of ancient Egypt. The topics studied include ancient Egyptian history, language, literature, religion, architecture and art from the 5th millennium BC until the end of its native religious practices in the 4th century AD. History First explorers The earliest explorers of ancient Egypt were the ancient Egyptians themselves. Inspired by a dream he had, Thutmose IV led an excavation of the Great Sphinx of Giza and inscribed a description of the dream on the Dream Stele. Less than two centuries later, Prince Khaemweset, fourth son of Ramesses II, would gain fame for identifying and restoring historic buildings, tombs and temples, including pyramids; and has subsequently been described as the first Egyptologist. Classical Antiquity Some of the first historical accounts of Egypt were given by Herodotus, Strabo, Diodorus Siculus and the largely lost work of Manetho, an Egyptian priest, during the reign of ...

Flinders Petrie
Sir William Matthew Flinders Petrie ( – ), commonly known as simply Sir Flinders Petrie, was an English people, English Egyptology, Egyptologist and a pioneer of systematic methodology in archaeology and the preservation of artefacts. He held the first chair of Egyptology in the United Kingdom, and excavated many of the most important archaeological sites in Egypt in conjunction with his Irish-born wife, Hilda Petrie, Hilda Urlin. Some consider his most famous discovery to be that of the Merneptah Stele, an opinion with which Petrie himself concurred. Undoubtedly at least as important is his 1905 discovery and correct identification of the character of the Proto-Sinaitic script, the ancestor of almost all alphabetic scripts. Petrie developed the system of dating layers based on pottery and Ceramic engineering, ceramic findings. Petrie has been denounced for his pro-eugenics views; he was a dedicated believer in the superiority of the Germanic-speaking world, Northern p ...

Egyptian Chronology
The Conventional Egyptian chronology reflects the broad scholarly consensus about the outline and many details of the chronology of Ancient Egypt. It places the beginning of the Old Kingdom in the 27th century BC, the beginning of the Middle Kingdom of Egypt, Middle Kingdom in the 21st century BC and the beginning of the New Kingdom of Egypt, New Kingdom in the mid-16th century BC. Disagreements remain within this consensus, and various chronologies diverge by about 300 years for the Early Dynastic Period of Egypt, Early Dynastic Period, up to 30 years in the New Kingdom of Egypt, New Kingdom, and a few years in the Late Period of ancient Egypt, Late Period. In addition, there are a number of "alternative chronologies" outside scholarly consensus, such as the "New Chronology (Rohl), New Chronology" proposed in the 1990s, which lowers New Kingdom dates by as much as 350 years, or the "Glasgow Chronology" (proposed 1978–1982), which lowers New Kingdom dates by as much as 500 yea ...

Seriation (archaeology)
In archaeology, seriation is a Relative dating#Archaeology, relative dating method in which assemblage (archaeology), assemblages or artifact (archaeology), artifacts from numerous sites in the same culture are placed in chronological order. Where absolute dating methods, such as radio carbon, cannot be applied, archaeologists have to use relative dating methods to date archaeological finds and features. Seriation is a standard method of dating in archaeology. It can be used to date stone tools, pottery fragments, and other artifacts. In Europe, it has been used frequently to reconstruct the chronological sequence of graves in a cemetery (e.g. Jørgensen 1992; Müssemeier, Nieveler et al. 2003). Contextual and frequency seriation Two different variants of seriation have been applied: contextual seriation and frequency seriation (Renfrew and Bahn 1996, pp. 116–117). Whereas contextual seriation is based on the presence or absence of a Style (visual arts)#Style in arch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
