Solomon’s Knot
Solomon's knot () is a traditional decorative motif used since ancient times, and found in many cultures. Despite the name, it is classified as a link, and is not a true knot according to the definitions of mathematical knot theory. Structure The Solomon's knot consists of two closed loops, which are doubly interlinked in an interlaced manner. If laid flat, the Solomon's knot is seen to have four crossings where the two loops interweave under and over each other. This contrasts with two crossings in the simpler Hopf link. In most artistic representations, the parts of the loops that alternately cross over and under each other become the sides of a central square, while four loopings extend outward in four directions. The four extending loopings may have oval, square, or triangular endings, or may terminate with free-form shapes such as leaves, lobes, blades, wings etc. Occurrences The Solomon's knot often occurs in ancient Roman mosaics, usually represented as two inter ...

Polygonatum
''Polygonatum'' , also known as King Solomon's-seal or Solomon's seal, is a genus of flowering plants. In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). It has also been classified in the former family Convallariaceae and, like many lilioid monocots, was formerly classified in the lily family, Liliaceae. The genus is distributed throughout the temperate Northern Hemisphere. Most of the approximately 63 species occur in Asia, with 20 endemic to China.Wujisguleng, W., et al. (2012)Ethnobotanical review of food uses of ''Polygonatum'' (Convallariaceae) in China.''Acta Societatis Botanicorum Poloniae'' 81(4) 239-44. Etymology ''Polygonatum'' comes from the ancient Greek for "many knees", referring to the multiple jointed rhizome. One explanation for the derivation of the common name "Solomon's seal" is that the roots bear depressions which resemble royal seals. Another is that the cut roots resembl ...

Powell Library
Powell Library is the main college undergraduate library on the campus of the University of California, Los Angeles (UCLA). Powell Library is also known as the College Library. It was constructed from 1926 to 1929 and was one of the original four buildings that comprised the UCLA campus in the early period of the university's life. Its Romanesque Revival architecture design, its historic value and its popularity with students make it one of the defining images of UCLA. Style Like the building facing it across the quad, Royce Hall, the building's exterior is modeled after Milan's Basilica of Sant'Ambrogio. The entrance of the library is adorned with several mosaics, one of which depicts two men holding a book bearing the phrase, from Cicero's ''Pro Archia Poeta'', "''Haec studia adulescentiam alunt, senectutem oblectant''" ("These studies nourish youth and delight old age"), an appropriate dictum for the vast collection for undergraduate students. There are also Renaissance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Solomon's Knot AngewChemIntEd 2007 V46 P218
A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion. In quantum physics, organic chemistry, and biochemistry, the distinction from ions is dropped and ''molecule'' is often used when referring to polyatomic ions. A molecule may be homonuclear, that is, it consists of atoms of one chemical element, e.g. two atoms in the oxygen molecule (O2); or it may be heteronuclear, a chemical compound composed of more than one element, e.g. water (two hydrogen atoms and one oxygen atom; H2O). In the kinetic theory of gases, the term ''molecule'' is often used for any gaseous particle regardless of its composition. This relaxes the requirement that a molecule contains two or more atoms, since the noble gases are individual atoms. Atoms and complexes connected by non-covalent interactions, such as hydrogen bonds or ionic bonds, are typically not consid ...

Ostia (Rome)
Ostia (, ; officially Lido di Ostia) is a large neighbourhood in the X Municipio of the ''comune'' of Rome, Italy, near the ancient port of Rome, which is now a major archaeological site known as Ostia Antica. Ostia is also the only or district of Rome on the Tyrrhenian Sea, and many Romans spend the summer holidays there. History Ostia Antica had been the port city of ancient Rome, and is often referenced in writings from the times of the Roman Republic and the Roman Empire. For Christian posterity, Ostia Antica was especially important as the site of the death of Saint Monica (mother of Saint Augustine) in 387 in a house property of the Diocesi of Rome, on their way back to Africa after Augustine's conversion to Christianity. An important stand in Italian nationalism of the 19th century was a veneration for the glories of the Roman past, manifested in a wish to revive or recreate various places and institutions connected with Ancient Rome. In 1871, the city of Rome became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kuba Kingdom
The Kuba Kingdom, also known as the Kingdom of the Bakuba or Bushongo, is a traditional kingdom in Central Africa. The Kuba Kingdom flourished between the 17th and 19th centuries in the region bordered by the Sankuru, Lulua, and Kasai rivers in the heart of the modern-day Democratic Republic of the Congo. The Kuba Kingdom was a conglomerate of several smaller Bushongo-speaking principalities as well as the Kete, Coofa, Mbeengi, and the Kasai Twa Pygmies. The original Kuba migrated during the 16th century from the north. Nineteen different ethnic groups are included in the kingdom, which still exists and is presided over by the King (''nyim''). History Shyaam a-Mbul The kingdom began as a conglomeration of several chiefdoms of various ethnic groups with no real central authority. In approximately 1625, an individual from outside the area known as Shyaam a-Mbul a Ngoong usurped the position of one of the area rulers and united all the chiefdoms under his leadership. Tradi ...

Macramé
Macramé is a form of textile produced using knotting (rather than weaving or knitting) techniques. The primary knots of macramé are the square (or reef knot) and forms of "hitching": various combinations of half hitches. It was long crafted by sailors, especially in elaborate or ornamental knotting forms, to cover anything from knife handles to bottles to parts of ships. Cavandoli macramé is one variety that is used to form geometric and free-form patterns like weaving. The Cavandoli style is done mainly in a single knot, the double half-hitch knot. Reverse half hitches are sometimes used to maintain balance when working left and right halves of a balanced piece. Leather or fabric belts are another accessory often created via macramé techniques. Most friendship bracelets exchanged among schoolchildren and teens are created using this method. Vendors at theme parks, malls, seasonal fairs and other public places may sell macramé jewelry or decoration as well. History One ...

Crochet
Crochet (; ) is a process of creating textiles by using a crochet hook to interlock loops of yarn, thread (yarn), thread, or strands of other materials. The name is derived from the French term ''crochet'', meaning 'hook'. Hooks can be made from a variety of materials, such as metal, wood, bamboo, or plastic. The key difference between crochet and knitting, beyond the implements used for their production, is that each stitch in crochet is completed before the next one is begun, while knitting keeps many stitches open at a time. Some variant forms of crochet, such as Tunisian crochet and broomstick lace, do keep multiple crochet stitches open at a time. Etymology The word crochet is derived from the Old French ''crochet'', a diminutive of ''croche'', in turn from the Germanic languages, Germanic ''croc'', both meaning "hook". It was used in 17th-century French lace-making, where the term ''crochetage'' designated a stitch used to join separate pieces of lace. The word ''crochet'' ...

Pentagram
A pentagram (sometimes known as a pentalpha, pentangle, or star pentagon) is a regular five-pointed star polygon, formed from the diagonal line segments of a convex (or simple, or non-self-intersecting) regular pentagon. Drawing a circle around the five points creates a similar symbol referred to as the pentacle, which is used widely by Wiccans and in paganism, or as a sign of life and connections. The word "pentagram" refers only to the five-pointed star, not the surrounding circle of a pentacle. Pentagrams were used symbolically in ancient Greece and Babylonia. Christians once commonly used the pentagram to represent the Five Holy Wounds, five wounds of Jesus. Today the symbol is widely used by the Wiccans, witches, and pagans. The pentagram has Magic (supernatural), magical associations. Many people who practice neopaganism wear jewelry incorporating the symbol. The word ''pentagram'' comes from the Greek language, Greek word πεντάγραμμον (''pentagrammon''), fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
