Sunburst
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, military decorations and badges. Sunbursts can appear in photographs when taking a picture of the Sun throug ...

Monstrance
A monstrance, also known as an ostensorium (or an ostensory), is a vessel used in Roman Catholic, Old Catholic, High Church Lutheran and Anglican churches for the display on an altar of some object of piety, such as the consecrated Eucharistic Sacramental bread (host) during Eucharistic adoration or during the Benediction of the Blessed Sacrament. A monstrance may also serve as a reliquary for the public display of relics of some saints."" New Advent Catholic Encyclopedia. Retrieved on 2014-11-16.

Sunburst Chart
A pie chart (or a circle chart) is a circular 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 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 more difficult to make simple comparisons such as the size of different sections of a given pie chart, or t ...

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 Battle of Auray, 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 Royal Badges of England, 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. Holders of the office See also * Heraldry * Officer of arms References Cita ...

Art Deco
Art Deco, short for the French (), is a style of visual arts, architecture, and product design that first Art Deco in Paris, appeared in Paris in the 1910s just before World War I and flourished in the United States and Europe during the 1920s to early 1930s, through styling and design of the exterior and interior of anything from large structures to small objects, including clothing, fashion, and jewelry. Art Deco has influenced buildings from skyscrapers to cinemas, bridges, ocean liners, trains, cars, trucks, buses, furniture, and everyday objects, including radios and vacuum cleaners. The name Art Deco came into use after the 1925 (International Exhibition of Modern Decorative and Industrial Arts) held in Paris. It has its origin in the bold geometric forms of the Vienna Secession and Cubism. From the outset, Art Deco was influenced by the bright colors of Fauvism and the Ballets Russes, and the exoticized styles of art from Chinese art, China, Japanese art, Japan, Indian ...

Votive Crown
A votive crown is a votive offering in the form of a crown, normally in precious metals and often adorned with jewels. Especially in the Early Middle Ages, they are of a special form, designed to be suspended by chains at an altar, shrine or image. Later examples are more often typical crowns in the style of the period, either designed to be placed on the head of a statue, or re-used in this way after donation. Pre-Christian examples There were pagan votive crowns in the ancient world, although these are essentially known only from literary references. Vitruvius records that when Hiero II of Syracuse (died 215 BC) suspected his goldsmith of cheating him over the making of a votive crown for a statue in a temple, for which he had supplied the gold to be used, he asked Archimedes to devise a test. This led Archimedes to his famous '' eureka'' moment, after he realized he could test the crown by comparing its displacement of water to that of the same weight of pure gold; in fact th ...

Sun Icon
The Sun is the star at the centre of the Solar System. It is a massive, nearly perfect sphere of hot Plasma (physics), plasma, heated to incandescence by nuclear fusion reactions in its core, radiating the energy from its surface mainly as visible light and infrared radiation with 10% at ultraviolet energies. It is by far the most important source of energy for life on Earth. The Sun has been an The Sun in culture, object of veneration in many cultures. It has been a central subject for astronomical research since Ancient history, antiquity. The Sun orbits the Galactic Center at a distance of 24,000 to 28,000 light-years. Its distance from Earth defines the astronomical unit, which is about or about 8 light-minutes. Solar radius, Its diameter is about (), 109 times that of Earth. solar mass, The Sun's mass is about 330,000 times that of Earth, making up about 99.86% of the total mass of the Solar System.

Diffraction
Diffraction is the deviation of waves from straight-line propagation without any change in their energy due to an obstacle or through an aperture. The diffracting object or aperture effectively becomes a secondary source of the Wave propagation, propagating wave. Diffraction is the same physical effect as Wave interference, interference, but interference is typically applied to superposition of a few waves and the term diffraction is used when many waves are superposed. Italian scientist Francesco Maria Grimaldi coined the word ''diffraction'' and was the first to record accurate observations of the phenomenon in 1660 in science, 1660. In classical physics, the diffraction phenomenon is described by the Huygens–Fresnel principle that treats each point in a propagating wavefront as a collection of individual spherical wavelets. The characteristic pattern is most pronounced when a wave from a Coherence (physics), coherent source (such as a laser) encounters a slit/aperture tha ...

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. While similar in appearance, this is a different effect to "vertical smear" or "blooming" that appears when bright light sources are captured by a charge-coupled device (CCD) image sensor. Causes 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 telescope 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 l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Information Visualization
Data and information visualization (data viz/vis or info viz/vis) is the practice of designing and creating Graphics, graphic or visual Representation (arts), representations of a large amount of complex quantitative and qualitative data and information with the help of static, dynamic or interactive visual items. Typically based on data and information collected from a certain domain of expertise, these visualizations are intended for a broader audience to help them visually explore and discover, quickly understand, interpret and gain important insights into otherwise difficult-to-identify structures, relationships, correlations, local and global patterns, trends, variations, constancy, clusters, outliers and unusual groupings within data (''exploratory visualization''). When intended for the general public (mass communication) to convey a concise version of known, specific information in a clear and engaging manner (''presentational'' or ''explanatory visualization''), it is t ...
