Dendera Light
The Dendera light is a motif in the Hathor temple at Dendera in Egypt. It depicts the Egyptian creation myth, and the text surrounding the pieces confirm this. The temple contains several reliefs depicting Harsomtus, in the form of a snake, emerging from a lotus flower which is usually attached to the bow of a barge. The so-called dendera light is a variation of this motif, showing Harsomtus in an oval container called ''hn'', which might represent the womb of Nut. Sometimes a ''djed'' pillar supports the snake or the container. A closely related motif is "god resting on the lotus flower". Depictions and text Each of the three objects consists of two reliefs. One half (a) of each pair is in south crypt 1-C (crypte 4), the other half (b) in room G (chambre V) of the temple. Similar motifs File:Denderah. Grand temple.

Motif (visual Arts)
In art and iconography, a motif () is an element of an image. The term can be used both of figurative and narrative art, and ornament and geometrical art. A motif may be repeated in a pattern or design, often many times, or may just occur once in a work. A motif may be an element in the iconography of a particular subject or type of subject that is seen in other works, or may form the main subject, as the Master of Animals motif in ancient art typically does. The related motif of confronted animals is often seen alone, but may also be repeated, for example in Byzantine silk and other ancient textiles. Where the main subject of an artistic work such as a painting is a specific person, group, or moment in a narrative, that should be referred to as the "subject" of the work, not a motif, though the same thing may be a "motif" when part of another subject, or part of a work of decorative art such as a painting on a vase. Ornamental or decorative art can usually be analysed in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arc Lamp
An arc lamp or arc light is a lamp that produces light by an electric arc (also called a voltaic arc). The carbon arc light, which consists of an arc between carbon electrodes in air, invented by Humphry Davy in the first decade of the 1800s, was the first practical electric light. It was widely used starting in the 1870s for street and large building lighting until it was superseded by the incandescent light in the early 20th century. It continued in use in more specialized applications where a high intensity point light source was needed, such as searchlights and movie projectors until after World War II. The carbon arc lamp is now obsolete for most of these purposes, but it is still used as a source of high intensity ultraviolet light. The term is now used for gas discharge lamps, which produce light by an arc between metal electrodes through a gas in a glass bulb. The common fluorescent lamp is a low-pressure mercury arc lamp. The xenon arc lamp, which produces a high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Egyptology
Egyptology (from ''Egypt'' and Greek , '' -logia''; ar, علم المصريات) is the study of 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. A practitioner of the discipline is an " Egyptologist". In Europe, particularly on the Continent, Egyptology is primarily regarded as being a philological discipline, while in North America it is often regarded as a branch of archaeology. 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 ...

Science And Pseudoscience In Archaeology
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

Egyptian Mythology
Egyptian mythology is the collection of myths from ancient Egypt, which describe the actions of the Egyptian gods as a means of understanding the world around them. The beliefs that these myths express are an important part of ancient Egyptian religion. Myths appear frequently in Egyptian writings and art, particularly in short stories and in religious material such as hymns, ritual texts, funerary texts, and temple decoration. These sources rarely contain a complete account of a myth and often describe only brief fragments. Inspired by the cycles of nature, the Egyptians saw time in the present as a series of recurring patterns, whereas the earliest periods of time were linear. Myths are set in these earliest times, and myth sets the pattern for the cycles of the present. Present events repeat the events of myth, and in doing so renew '' maat'', the fundamental order of the universe. Amongst the most important episodes from the mythic past are the creation myths, in wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Occam's Razor
Occam's razor, Ockham's razor, or Ocham's razor ( la, novacula Occami), also known as the principle of parsimony or the law of parsimony ( la, lex parsimoniae), is the problem-solving principle that "entities should not be multiplied beyond necessity". It is generally understood in the sense that with competing theories or explanations, the simpler one, for example a model with fewer parameters, is to be preferred. The idea is frequently attributed to English Franciscan friar William of Ockham (), a scholastic philosopher and theologian, although he never used these exact words. This philosophical razor advocates that when presented with competing hypotheses about the same prediction, one should select the solution with the fewest assumptions, and that this is not meant to be a way of choosing between hypotheses that make different predictions. Similarly, in science, Occam's razor is used as an abductive heuristic in the development of theoretical models rather than as a rigoro ...

Kenneth Feder
Kenneth L. "Kenny" Feder (born August 1, 1952) is a professor of archaeology at Central Connecticut State University and the author of several books on archaeology and criticism of pseudoarchaeology such as '' Frauds, Myths, and Mysteries: Science and Pseudoscience in Archaeology''. His book ''Encyclopedia of Dubious Archaeology: From Atlantis to the Walam Olum'' was published in 2010. His book ''Ancient America: Fifty Archaeological Sites to See for Yourself'' was published in 2017. He is the founder and director of the Farmington River Archaeological Project. Early life Feder was very interested in cryptozoology and ancient astronauts as a teenager, when a book called '' Morning of the Magicians'' about extraterrestrial aliens turned him on to what he describes as the nonsense in archaeology. "Essentially it was Erich von Däniken before Erich von Däniken", referring to the popular author and popularizer of ancient astronaut theories. "I knew it was crap and it got me reall ...

Debunker
A debunker is a person or organization that exposes or discredits claims believed to be false, exaggerated, or pretentious. "to expose or excoriate (a claim, assertion, sentiment, etc.) as being pretentious, false, or exaggerated: to debunk advertising slogans." The term is often associated with skeptical investigation of controversial topics such as UFOs, claimed paranormal phenomena, cryptids, conspiracy theories, alternative medicine, religion, or exploratory or fringe areas of scientific or pseudoscientific research. According to the Merriam-Webster online dictionary, to "debunk" is defined as: "to expose the sham or falseness of." The ''New Oxford American Dictionary'' defines "debunk" as "expose the falseness or hollowness of (a myth, idea, or belief)". If debunkers are not careful, their communications may backfire – increasing an audience's long-term belief in myths. Backfire effects can occur if a message spends too much time on the negative case, if it is too co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lampblack
Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of coal and coal tar, vegetable matter, or petroleum products, including fuel oil, fluid catalytic cracking tar, and ethylene cracking. Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon. It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly lower (negligible and non-bioavailable) polycyclic aromatic hydrocarbon (PAH) content. However, carbon black can be used as a model compound for diesel soot to better understand how diesel soot behaves under various reaction conditions as carbon black and diesel soot have some similar properties such as particle sizes, densities, and copolymer adsorption abilities that contribute to them having similar behaviours under various reactions such as oxidation experiments ...

Norman Lockyer
Sir Joseph Norman Lockyer (17 May 1836 – 16 August 1920) was an English scientist and astronomer. Along with the French scientist Pierre Janssen, he is credited with discovering the gas helium. Lockyer also is remembered for being the founder and first editor of the influential journal ''Nature''. Biography Lockyer was born in Rugby, Warwickshire. His early introduction to science was through his father, who was a pioneer of the electric telegraph. After a conventional schooling supplemented by travel in Switzerland and France, he worked for some years as a civil servant in the British War Office. He settled in Wimbledon, South London after marrying Winifred James, who helped translate at least four French scientific works into English. He was a keen amateur astronomer with a particular interest in the Sun. In 1885 he became the world's first professor of astronomical physics at the Royal College of Science, South Kensington, now part of Imperial College. At the colle ...

Crookes Tube
A Crookes tube (also Crookes–Hittorf tube) is an early experimental electrical discharge tube, with partial vacuum, invented by English physicist William Crookes and others around 1869-1875, in which cathode rays, streams of electrons, were discovered. Developed from the earlier Geissler tube, the Crookes tube consists of a partially evacuated glass bulb of various shapes, with two metal electrodes, the cathode and the anode, one at either end. When a high voltage is applied between the electrodes, cathode rays ( electrons) are projected in straight lines from the cathode. It was used by Crookes, Johann Hittorf, Julius Plücker, Eugen Goldstein, Heinrich Hertz, Philipp Lenard, Kristian Birkeland and others to discover the properties of cathode rays, culminating in J.J. Thomson's 1897 identification of cathode rays as negatively charged particles, which were later named '' electrons''. Crookes tubes are now used only for demonstrating cathode rays. Wilhelm Rö ...
