Flexible Glass
Flexible glass is an alleged lost invention from the time of the reign of Tiberius Caesar. It may also refer to a form used today in fiber optic cables, though it is unknown if they are the same material. History and mythology Supposedly, the inventor of flexible glass (''vitrum flexile'') brought a drinking bowl made of the material before Tiberius Caesar. The bowl was put through a test to break it, but it merely dented, rather than shattering. The inventor repaired the bowl very easily with a small hammer, which he pulled from a pocket in his toga, according to Petronius. After the inventor swore that he was the only man alive who knew the manufacturing technique, Tiberius had the man beheaded. He feared that the glass would devalue gold and silver, since the material might be more valuable. The account is most popularly related by two compilers, Pliny the Elder (, Naturalis Historia XXXVI.lxvi.195) and Petronius (, ''Satyricon'' 51). Pliny claims that the story of flexible ...

Foldable Smartphone
A foldable smartphone (also known as a foldable phone or simply foldable) is a smartphone with a folding form factor. Some variants of the concept use multiple touchscreen panels on a hinge, while other designs utilise a flexible display. Concepts of such devices date back as early as Nokia's "Morph" concept in 2008, and a concept presented by Samsung Electronics in 2013 (as part of a larger set of concepts utilizing flexible OLED displays), while the first commercially available folding smartphones with OLED displays began to emerge in November 2018. Some devices may fold out on a vertical axis to into a wider, tablet-like form, but are still usable in a smaller, folded state; the display may either wrap around to the back of the device when folded (as with the Royole FlexPai and Huawei Mate X), or use a booklet-like design where the larger, folded screen is located on the interior, and a screen on its "cover" allows the user to interact with the device without opening it ...

Isidore Of Seville
Isidore of Seville ( la, Isidorus Hispalensis; c. 560 – 4 April 636) was a Spanish scholar, theologian, and archbishop of Seville. He is widely regarded, in the words of 19th-century historian Montalembert, as "the last scholar of the ancient world". At a time of disintegration of classical culture, aristocratic violence and widespread illiteracy, Isidore was involved in the conversion of the Arian Visigothic kings to Catholicism, both assisting his brother Leander of Seville and continuing after his brother's death. He was influential in the inner circle of Sisebut, Visigothic king of Hispania. Like Leander, he played a prominent role in the Councils of Toledo and Seville. His fame after his death was based on his '' Etymologiae'', an etymological encyclopedia that assembled extracts of many books from classical antiquity that would have otherwise been lost. This work also helped standardize the use of the period (full stop), comma, and colon. Since the ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass Types
Glass is a non-crystalline, often transparent, amorphous solid that has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the molten form; some glasses such as volcanic glass are naturally occurring. The most familiar, and historically the oldest, types of manufactured glass are "silicate glasses" based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. Soda–lime glass, containing around 70% silica, accounts for around 90% of manufactured glass. The term ''glass'', in popular usage, is often used to refer only to this type of material, although silica-free glasses often have desirable properties for applications in modern communications technology. Some objects, such as drinking glasses and eyeglasses, are so commonly made of silicate-based glass that they are simply called by the name of the material. Despite bei ...

History Of Glass
The history of glass-making dates back to at least 3,600 years ago in Mesopotamia. However, some writers claim that they may have been producing copies of glass objects from Egypt. Other archaeological evidence suggests that the first true glass was made in coastal north Syria, Mesopotamia or Egypt. The earliest known glass objects, of the mid 2,000 BCE, were beads, perhaps initially created as the accidental by-products of metal-working (slags) or during the production of faience, a pre-glass vitreous material made by a process similar to glazing. Glass products remained a luxury until the disasters that overtook the late Bronze Age civilizations seemingly brought glass-making to a halt. Development of glass technology in India may have begun in 1,730 BCE. In Ancient China, glass-making had a later start compared to ceramics and metal work. From across the former Roman Empire, archaeologists have recovered glass objects that were used in domestic, industrial and funerary c ...

Schott AG
Schott AG is a German multinational glass company specializing in the manufacture of glass and glass-ceramics. Headquartered in Mainz, Germany, it is owned by the Carl Zeiss Foundation. The company's founder and namesake, Otto Schott, is credited with the invention of borosilicate glass. History Founding In 1884, Otto Schott, Ernst Abbe, Carl Zeiss and his son Roderich Zeiss founded the ''Glastechnische Laboratorium Schott & Genossen'' (Glass Technical Laboratory Schott & Associates) in Jena, which initially produced optical glasses for microscopes and telescopes. In 1891, the Carl Zeiss Foundation founded two years earlier by Ernst Abbe became a partner in the glass laboratory. Jena glass, an early borosilicate glass, was one of its early manufactured products. The invention of borosilicate glass, resistant to chemicals, heat and temperature change, paved the way for new technical glasses for thermometers, laboratory equipment and gas lamps.

Borosilicate Glass
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10−6 K−1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials without fracturing of about . It is commonly used for the construction of reagent bottles and flasks as well as lighting, electronics, and cookware. Borosilicate glass is sold under various trade names, including Borosil, Duran, Pyrex, Glassco, Supertek, Suprax, Simax, Bellco, Marinex (Brazil), BSA 60, BSC 51 (by NIPRO), Heatex, Endural, Schott, Refmex, Kimax, Gemstone Well, and MG (India). Single ended self-starting lamps are insulated with a mica disc and contained in a borosilicate glass gas discharge tube (arc tube) and a metal cap. They include the sodium-vapor la ...

Willow Glass
Gorilla Glass is a brand of chemically strengthened glass developed and manufactured by Corning, now in its seventh generation. Designed to be thin, light and damage-resistant, the glass gains its surface strength, ability to contain flaws, and crack-resistance by being immersed in a hot, potassium-salt, ion-exchange bath. As a brand, Gorilla Glass is specific to Corning, but close equivalents exist, including AGC Inc.'s Dragontrail and Schott AG's Xensation. The alkali-aluminosilicate sheet glass is used primarily as cover glass for portable electronic devices, including mobile phones, smartwatches, portable media players, portable computer displays, and television screens. It is manufactured in Harrodsburg, Kentucky; in Asan, South Korea; and in Taiwan. In October 2017, some five billion devices globally contained Gorilla Glass.

Fiber Optic Illuminated
Fiber or fibre (from la, fibra, links=no) is a natural or artificial substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene. Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers can give some benefits, such as comfort, over their synthetic counterparts. Natural fibers Natural fibers develop or occur in the fiber shape, and include those produced by plants, animals, and geological processes. They can be classified according to their origin: * Vegetable fibers are generally based on arrangements of cellulose, often with lignin: examples include cotton, hemp, jute, flax, abaca, piña, ramie, sisal, bagasse, and banana. Plant fibers are employed in the manufacture of paper and textile (cloth), and di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Satyricon
The ''Satyricon'', ''Satyricon'' ''liber'' (''The Book of Satyrlike Adventures''), or ''Satyrica'', is a Latin work of fiction believed to have been written by Gaius Petronius, though the manuscript tradition identifies the author as Titus Petronius. The ''Satyricon'' is an example of Menippean satire, which is different from the formal verse satire of Juvenal or Horace. The work contains a mixture of prose and verse (commonly known as ); serious and comic elements; and erotic and decadent passages. As with ''The Golden Ass'' by Apuleius (also called the ''Metamorphoses''), classical scholars often describe it as a Roman novel, without necessarily implying continuity with the modern literary form. The surviving sections of the original (much longer) text detail the bizarre exploits of the narrator, Encolpius, and his (possible) slave and boyfriend Giton, a handsome sixteen-year-old boy. It is the second most fully preserved Roman novel, after the fully extant ''The Golden Ass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
