Mirror
A mirror or looking glass is an object that Reflection (physics), reflects an image. Light that bounces off a mirror will show an image of whatever is in front of it, when focused through the lens of the eye or a camera. Mirrors reverse the direction of the image in an equal yet opposite angle from which the light shines upon it. This allows the viewer to see themselves or objects behind them, or even objects that are at an angle from them but out of their field of view, such as around a corner. Natural mirrors have existed since prehistoric times, such as the surface of water, but people have been manufacturing mirrors out of a variety of materials for thousands of years, like stone, metals, and glass. In modern mirrors, metals like silver or aluminium are often used due to their high reflectivity, applied as a thin coating on glass because of its naturally smooth and very Hardness (materials science), hard surface. A mirror is a Wave (physics), wave reflector. Light consis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Erynnini
The Erynnini are a tribe in the skipper butterfly subfamily Pyrginae. They are a moderately diverse but quite plesiomorphic and inconspicuous group, and except for the Holarctic species of the type genus ''Erynnis'' occur only in the Neotropics.Brower (2009) Formerly, when only four tribes of Pyrginae were recognized, they were included in the Pyrgini, which at that time contained a massive number of genera. But the Pyrginae have since been reorganized to make them and their tribes monophyletic, leading most modern authors to treat the Erynnini as distinct tribe. However, the old circumscription of the Pyrgini was by and large just as correct from a phylogenetic perspective. The tribe of the Pyrgini ''sensu lato'' most closely related to the Pyrgini ''sensu stricto'' are the strikingly different Achlyodidini. As many consider it desirable to treat this lineage as a distinct tribe, the Erynnini naturally need to be considered distinct too. Genera The genera are listed he ...

Speculum (journal)
''Speculum: A Journal of Medieval Studies'' is a quarterly academic journal published by University of Chicago Press on behalf of the Medieval Academy of America. Established in 1926 by Edward Kennard Rand, it is widely regarded as the most prestigious journal in medieval studies. The journal's primary focus is on the time period from 500 to 1500 in Western Europe, but also on related subjects such as Byzantine, Hebrew, Arabic, Armenian and Slavic studies. , the editor is Katherine L. Jansen. The organization and its journal were first proposed in 1921 at a meeting of the Modern Language Association, and the journal's focus was interdisciplinary from its beginning, with one reviewer noting a specific interest in Medieval Latin Medieval Latin was the form of Literary Latin used in Roman Catholic Western Europe during the Middle Ages. In this region it served as the primary written language, though local languages were also written to varying degrees. Latin functioned .... R ...

Speculum (medical)
A speculum (Latin for 'mirror'; plural specula or speculums) is a medical tool for investigating body orifices, with a form dependent on the orifice for which it is designed. In old texts, the speculum may also be referred to as a diopter or dioptra. Like an endoscope, a speculum allows a view inside the body; endoscopes, however, tend to have optics while a speculum is intended for direct vision. History Vaginal and anal specula were used by the ancient Greeks and Romans, and speculum artifacts have been found in Pompeii. A vaginal speculum, developed by J. Marion Sims, consists of a hollow cylinder with a rounded end that is divided into two hinged parts, somewhat like the beak of a duck. This speculum is inserted into the vagina to dilate it for examination of the vagina and cervix. The modern vaginal speculum was developed by J. Marion Sims, a plantation doctor in Lancaster County, South Carolina. Between 1845 and 1849, Sims performed dozens of surgeries, without anesthes ...

Speculum Feathers
The speculum is a patch, often distinctly coloured, on the secondary wing feathers, or ''remiges'', of some birds. Examples of the colour(s) of the speculum in a number of ducks are: * Common teal and green-winged teal: Iridescent green edged with buff. * Blue-winged teal: Iridescent green. The species' common name comes from the sky-blue wing coverts. * Crested duck and bronze-winged duck: Iridescent purple-bronze, edged white. * Pacific black duck: Iridescent green, edged light buff. * Mallard: Iridescent purple-blue with white edges. * American black duck: Iridescent violet bordered in black and may have a thin white trailing edge. * Northern pintail: Iridescent green in male and brown in female, both are white on trailing edge. * Gadwall: Both sexes have white inner secondaries. * Yellow-billed duck: Iridescent green or blue, bordered white. Bright wing speculums are also known from a number of other birds; among them are several parrots from the genus ''Amazona Amazo ...

Speculum Literature
The medieval genre of speculum literature, popular from the twelfth through the sixteenth centuries, was inspired by the urge to encompass encyclopedic knowledge within a single work. However, some of these works have a restricted scope and function as instructional manuals. In this sense the encyclopedia and the speculum are similar, but they are not the same genre. ''Specula'' as a genre ''Specula'' often offered mirrors of history, doctrine, or morals. Vincent of Beauvais' Speculum Maius which included the ''Mirror of Nature'', ''Mirror of History'', and ''Mirror of Doctrine'' is not often described as a core representative of the genre. One historian has surmised that this is because Vincent's work was intended to be an objective work which is at odds with ''speculum'' literature, since it "is a subjective genre". More usual members are found in this list: * Honorius Augustodunensis' ''Imago mundi'' (cited by Vincent of Beauvais as ''Speculum mundi'') and ''Speculum Ecclesia ...

Speculum Metal
Speculum metal is a mixture of around two-thirds copper and one-third tin, making a white brittle alloy that can be polished to make a highly reflective surface. It was used historically to make different kinds of mirrors from personal grooming aids to optical devices until it was replaced by more modern materials such as metal-coated glass mirrors. Speculum metal mixtures usually contain two parts copper to one part tin along with a small amount of arsenic, although there are other mixtures containing silver, lead, or zinc. This is about twice the proportion of tin to copper typically used in bronze alloys. Archaeologists and others prefer to call it "high-tin bronze", although this broad term is also used for other alloys such as bell metal, which is typically around 20% tin. Large speculum metal mirrors are hard to manufacture, and the alloy is prone to tarnish, requiring frequent re-polishing. However, it was the only practical choice for large mirrors in high-precision opt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ophrys Speculum
''Ophrys speculum'', the mirror orchid, is a species of ''Ophrys'' distributed throughout the Mediterranean that is pollinated exclusively by a single species of scoliid wasp. Description A terrestrial orchid up to 25 cm tall and each inflorescence carries between 2 and 8 large flowers. The plants often grow in groups. In bright sunshine the flowers are highly visible as the light reflects off the speculum in the centre of the lip – it is a bright iridescent purple/blue in colour and very glossy. The lip is three-lobed and bordered by a greenish-yellow border which is surrounded by a band of thick velvety hairs which are reddish brown. The sepals and petals are green and marked with violet spots or stripes. Distribution ''Ophrys speculum'' is spread throughout the Mediterranean region, and is particularly prolific in the Algarve region of Portugal. It becomes more scarce in the east. Other countries in Europe where this orchid is known to occur include Spain, Cyprus and G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
