Sunburst K-12 Schools
A sunburst is a design or figure commonly used in architectural ornaments and design patterns and possibly pattern books. It consists of rays or "beams" radiating out from a central disk in the manner of sunbeams. Sometimes part of a sunburst, a semicircular or semi-elliptical shape, is used. Traditional sunburst motifs usually show the rays narrowing as they get further from the centre; from the later 19th century they often get wider, as in the Japanese Rising Sun Flag, which is more appropriate in optical terms. In architecture, the sunburst is often used in window designs, including fanlights and rose windows, as well as in decorative motifs. The sunburst motif is characteristic of Baroque church metalwork, especially monstrances and votive crowns, and Art Deco and Art Nouveau styles as well as church architecture. A sunburst is frequently used in emblems and military decorations. Sunbursts can appear in photographs when taking a picture of the Sun through th ...

Sun Icon
The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared radiation, and is the most important source of energy for life on Earth. The Sun's radius is about , or 109 times that of Earth. Its mass is about 330,000 times that of Earth, comprising about 99.86% of the total mass of the Solar System. Roughly three-quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron. The Sun is a G-type main-sequence star (G2V). As such, it is informally, and not completely accurately, referred to as a yellow dwarf (its light is actually white). It formed approximately 4.6 billionAll numbers in this article are short scale. One billion is 109, or 1,000,000,000. years ago from the g ...

Military Decoration
Military awards and decorations are distinctions given as a mark of honor for military heroism, meritorious or outstanding service or achievement. DoD Manual 1348.33, 2010, Vol. 3 A decoration is often a medal consisting of a ribbon and a medallion. Civil decorations awarded to military personnel should not be considered military decorations, although some orders of chivalry have civil and military divisions. Decorations received by police and fire brigade personnel may sometimes be considered alongside military decorations, on which they may be modelled, although they are strictly not military awards. History Decorations have been known since ancient times. The Egyptian Old Kingdom had the Order of the Golden Collar while the New Kingdom awarded the Order of the Golden Fly. Celts and Romans wore a torc or received other military decorations such as the ''hasta pura'', a spear without a tip. Dayaks wore and still wear tattoos, etc. Necklaces and bracelets were given during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Japanese Army
The was the official ground-based armed force of the Empire of Japan from 1868 to 1945. It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army, both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the Imperial Japanese Navy. Later an Inspectorate General of Aviation became the third agency with oversight of the army. During wartime or national emergencies, the nominal command functions of the emperor would be centralized in an Imperial General Headquarters (IGHQ), an ad hoc body consisting of the chief and vice chief of the Army General Staff, the Minister of the Army, the chief and vice chief of the Naval General Staff, the Inspector General of Aviation, and the Inspector General of Military Training. History Origins (1868–1871) In the mid-19th century, Japan had no unified national army and the country was made up of feudal domains (''han'') with the Tokugawa shogunate (''bakufu ...

Sunburst Chart
A pie chart (or a circle chart) is a circular Statistical graphics, statistical graphic, which is divided into slices to illustrate numerical proportion. In a pie chart, the arc length of each slice (and consequently its central angle and area) is Proportionality (mathematics), proportional to the quantity it represents. While it is named for its resemblance to a pie which has been sliced, there are variations on the way it can be presented. The earliest known pie chart is generally credited to William Playfair's ''Statistical Breviary'' of 1801.Spence (2005)Tufte, p. 44 Pie charts are very widely used in the business world and the mass media.Cleveland, p. 262 However, they have been criticized,Wilkinson, p. 23. and many experts recommend avoiding them,Tufte, p. 178.van Belle, p. 160–162.Stephen Few"Save the Pies for Dessert" August 2007, Retrieved 2010-02-02Steve Fento"Pie Charts Are Bad"/ref> as research has shown it is difficult to compare different sections of a given pi ...

Virgin Mary
Mary; arc, ܡܪܝܡ, translit=Mariam; ar, مريم, translit=Maryam; grc, Μαρία, translit=María; la, Maria; cop, Ⲙⲁⲣⲓⲁ, translit=Maria was a first-century Jewish woman of Nazareth, the wife of Joseph and the mother of Jesus. She is a central figure of Christianity, venerated under various titles such as virgin or queen, many of them mentioned in the Litany of Loreto. The Eastern and Oriental Orthodox, Church of the East, Catholic, Anglican, and Lutheran churches believe that Mary, as mother of Jesus, is the Mother of God. Other Protestant views on Mary vary, with some holding her to have considerably lesser status. The New Testament of the Bible provides the earliest documented references to Mary by name, mainly in the canonical Gospels. She is described as a young virgin who was chosen by God to conceive Jesus through the Holy Spirit. After giving birth to Jesus in Bethlehem, she raised him in the city of Nazareth in Galilee, and was in Jerusal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windsor Herald
Windsor Herald of Arms in Ordinary is an officer of arms at the College of Arms in London. It has been suggested that the office was instituted specifically for the Order of the Garter in 1348, or that it predates the Order and was in use as early as 1338. However, it is more likely that it dates from 1364, when a pursuivant of Edward III, on bringing the king news of the victory at Auray, was rewarded by promotion to the rank of herald with the title Windsor. Thereafter there is little mention of the office before 1419, when Windsor Herald was sent to the Duke of Brittany. Since that time, the office has been maintained. The badge of office is the sunburst badge of Edward III (Edward of Windsor) royally crowned. The best-known Windsor Herald was the 17th-century antiquarian, Elias Ashmole. The current Windsor Herald of Arms in Ordinary is John Allen-Petrie, Esq. Holders of the office See also * Heraldry * Officer of Arms References ;Citations ;Bibliography * ''The College ...

Heraldic Badge
A heraldic badge, emblem, impresa, device, or personal device worn as a badge indicates allegiance to, or the property of, an individual, family or corporate body. Medieval forms are usually called a livery badge, and also a cognizance. They are para-heraldic, not necessarily using elements from the coat of arms of the person or family they represent, though many do, often taking the crest or supporters. Their use is more flexible than that of arms proper. Badges worn on clothing were common in the late Middle Ages, particularly in England. They could be made of base metal, cloth or other materials and worn on the clothing of the followers of the person in question; grander forms would be worn by important persons, with the Dunstable Swan Jewel in enamelled gold a rare survivor. Livery collars were also given to important persons, often with the badge as a pendant. The badge would also be embroidered or appliqued on standards, horse trappings, livery uniforms, and other belongin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward III Of England
Edward III (13 November 1312 – 21 June 1377), also known as Edward of Windsor before his accession, was King of England and Lord of Ireland from January 1327 until his death in 1377. He is noted for his military success and for restoring royal authority after the disastrous and unorthodox reign of his father, Edward II. EdwardIII transformed the Kingdom of England into one of the most formidable military powers in Europe. His fifty-year reign was one of the longest in English history, and saw vital developments in legislation and government, in particular the evolution of the English Parliament, as well as the ravages of the Black Death. He outlived his eldest son, Edward the Black Prince, and the throne passed to his grandson, Richard II. Edward was crowned at age fourteen after his father was deposed by his mother, Isabella of France, and her lover Roger Mortimer. At age seventeen he led a successful coup d'état against Mortimer, the ''de facto'' ruler of the coun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Information Visualization
Information is an abstract concept that refers to that which has the power to inform. At the most fundamental level information pertains to the interpretation of that which may be sensed. Any natural process that is not completely random, and any observable pattern in any medium can be said to convey some amount of information. Whereas digital signals and other data use discrete signs to convey information, other phenomena and artifacts such as analog signals, poems, pictures, music or other sounds, and currents convey information in a more continuous form. Information is not knowledge itself, but the meaning that may be derived from a representation through interpretation. Information is often processed iteratively: Data available at one step are processed into information to be interpreted and processed at the next step. For example, in written text each symbol or letter conveys information relevant to the word it is part of, each word conveys information relevant ...

Sunstar (photography)
Diffraction spikes are lines radiating from bright light sources, causing what is known as the starburst effect or sunstars in photographs and in vision. They are artifacts caused by light diffracting around the support vanes of the secondary mirror in reflecting telescopes, or edges of non-circular camera apertures, and around eyelashes and eyelids in the eye. Diffraction spikes due to support vanes In the vast majority of reflecting telescope designs, the secondary mirror has to be positioned at the central axis of the telescope and so has to be held by struts within the telescopes tube. No matter how fine these support rods are they diffract the incoming light from a subject star and this appears as diffraction spikes which are the Fourier transform of the support struts. The spikes represent a loss of light that could have been used to image the star. Although diffraction spikes can obscure parts of a photograph and are undesired in professional contexts, some amateur a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
