Rimless Eyeglasses
Rimless eyeglasses are a type of eyeglasses in which the lenses are mounted directly to the bridge and/or temples. The style is divided into two subtypes: three-piece glasses are composed of lenses mounted to a bridge and two separate temple arms, while rimways (also called ''cortlands'') feature a supporting arch that connects the temples to the bridge and provides extra stability for the lenses. Rimless glasses were a popular style of eyeglasses from the 1880s until into the 1960s, and re-emerged in popularity in the latter part of the 20th century and early 21st century. Apple founder and former CEO Steve Jobs wore round rimless eyeglasses for 18 years, from 1993 until his death in 2011. Despite these shifts, they are unique among eyeglass styles in that they have never gone completely out of fashion, remaining an acceptable alternative through the years to more stylish designs. Mounting methods Rimless glasses lenses are held in place (or "mounted") by way of a series of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bullet Proof Glass
Bulletproof glass, ballistic glass, transparent armor, or bullet-resistant glass is a strong and optically transparent material that is particularly resistant to penetration by projectiles. Like any other material, it is not completely impenetrable. It is usually made from a combination of two or more types of glass, one hard and one soft. The softer layer makes the glass more elastic, so that it can flex instead of shatter. The index of refraction for all of the glasses used in the bulletproof layers must be almost the same to keep the glass transparent and allow a clear, undistorted view through the glass. Bulletproof glass varies in thickness from . Bulletproof glass is used in windows of buildings that require such security, such as jewelry stores and embassies, and of military and private vehicles. Construction Bullet-resistant glass is constructed using layers of laminated glass. The more layers there are, the more protection the glass offers. When a weight reduction i ...

Wear And Tear
Wear and tear is damage that naturally and inevitably occurs as a result of normal wear or aging. It is used in a legal context for such areas as warranty contracts from manufacturers, which usually stipulate that damage from ''wear and tear'' will not be covered. Wear and tear is a form of depreciation which is assumed to occur even when an item is used competently and with care and proper maintenance. For example, repeated impacts may cause stress to a hammer's head. This stress is impossible to prevent in the normal use of the tool for its designed task, and any attempt to avert it impedes its functionality. At the same time, it is expected that the normal use of a hammer will not break it beyond repair during a reasonable life cycle. The phenomenon of wear and tear reflects the second law of thermodynamics, in which objects stray from their original form and function over time unless energy from an external force is used to maintain them. If restoration is impossible, an ob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CR-39
Poly(allyl diglycol carbonate) (PADC) is a plastic commonly used in the manufacture of eyeglass lenses alongside the material PMMA (polymethyl methacrylate). The monomer is allyl diglycol carbonate (ADC). The term CR-39 technically refers to the ADC monomer, but is more commonly used to refer to the finished plastic. The abbreviation stands for "Columbia Resin #39", which was the 39th formula of a thermosetting plastic developed by the Columbia Resins project in 1940. The first commercial use of CR-39 monomer (ADC) was to help create glass-reinforced plastic fuel tanks for the B-17 bomber aircraft in World War II, reducing the weight and increasing the range of the bomber. After the war, the Armorlite Lens Company in California is credited with manufacturing the first CR-39 eyeglass lenses in 1947. CR-39 plastic has an index of refraction of 1.498 and an Abbe number of 58. CR-39 is now a trade-marked product of PPG Industries. An alternative use includes a purified version ...

Asia
Asia (, ) is one of the world's most notable geographical regions, which is either considered a continent in its own right or a subcontinent of Eurasia, which shares the continental landmass of Afro-Eurasia with Africa. Asia covers an area of , about 30% of Earth's total land area and 8.7% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Its 4.7 billion people constitute roughly 60% of the world's population. In general terms, Asia is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a historical and cultural construct, as there is no clear physical and geographical separation between them. It is somewhat arbitrary and has moved since its first conception in classical antiquity. The division of Eurasia into two continents reflects East–West cultural, linguistic, ...

Horn-rimmed Glasses
Horn-rimmed glasses are a type of eyeglasses. Originally made out of either horn or tortoise shell, for most of their history they have actually been constructed out of thick plastics designed to imitate those materials. They are characterized by their bold appearance on the wearer's face, in contrast to metal frames, which appear less pronounced. Horn-rimmed glasses were one of the first styles of eyeglasses to become a popular fashion item, after comedian Harold Lloyd began wearing a round pair in his films. The glasses have enjoyed various periods of popularity throughout the 20th century, being considered especially fashionable in the 1920s–1930s and in the 1950s–1960s in particular, while ceding to rimless and wire framed glasses during the 1970s and 1990s–2000s. Michael Caine's first appearance as Harry Palmer in ''The Ipcress File'' in 1965 featured his signature look of thick horn-rimmed glasses which made him a style icon of the 1960s. The style has brought a resur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2008 United States Presidential Election
The 2008 United States presidential election was the 56th quadrennial presidential election, held on Tuesday, November 4, 2008. The Democratic ticket of Barack Obama, the junior senator from Illinois, and Joe Biden, the senior senator from Delaware, defeated the Republican ticket of John McCain, the senior senator from Arizona, and Sarah Palin, the governor of Alaska. Obama became the first African American to be elected to the presidency, as well as being only the third sitting United States senator elected president, joining Warren G. Harding and John F. Kennedy. Meanwhile, Biden became the first senator running mate of a senator elected president since Lyndon B. Johnson (who was Kennedy's running mate) in the 1960 election. Incumbent Republican President George W. Bush was ineligible to pursue a third term due to the term limits established by the 22nd Amendment. McCain secured the Republican nomination by March 2008, defeating former governors Mitt Romney, Mike Hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarah Palin
Sarah Louise Palin (; Heath; born February 11, 1964) is an American politician, commentator, author, and reality television personality who served as the ninth governor of Alaska from 2006 until her resignation in 2009. She was the 2008 Republican vice presidential nominee alongside U.S. Senator John McCain. Palin was elected to the Wasilla city council in 1992 and became mayor of Wasilla in 1996. In 2003, after an unsuccessful run for lieutenant governor, she was appointed chair of the Alaska Oil and Gas Conservation Commission, responsible for overseeing the state's oil and gas fields for safety and efficiency. In 2006, at age 42, she became the youngest person and the first woman to be elected governor of Alaska. Immense legal fees incurred by both Palin and the state of Alaska from her fights against ethics investigations led to her resignation in 2009. Palin was nominated as John McCain's vice presidential running mate at the 2008 Republican National Convention. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polycarbonate
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications. Polycarbonates do not have a unique resin identification code (RIC) and are identified as "Other", 7 on the RIC list. Products made from polycarbonate can contain the precursor monomer bisphenol A (BPA). Structure Carbonate esters have planar OC(OC)2 cores, which confers rigidity. The unique O=C bond is short (1.173 Å in the depicted example), while the C-O bonds are more ether-like (the bond distances of 1.326 Å for the example depicted). Polycarbonates received their name because they are polymers containing carbonate groups (−O−(C=O)−O−). A balance of useful features, including temperature resistance, impact resistance and o ...

Titanium
Titanium is a chemical element with the symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll and Hunter processes. The most common compound, titanium dioxide, is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and catalysts; and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinrich Himmler
Heinrich Luitpold Himmler (; 7 October 1900 – 23 May 1945) was of the (Protection Squadron; SS), and a leading member of the Nazi Party of Germany. Himmler was one of the most powerful men in Nazi Germany and a main architect of the Holocaust. As a member of a reserve battalion during World War I, Himmler did not see active service, and did not fight. He studied agriculture in university, and joined the Nazi Party in 1923 and the SS in 1925. In 1929, he was appointed by Adolf Hitler. Over the next 16 years, he developed the SS from a 290-man battalion into a million-strong paramilitary group, and set up and controlled the Nazi concentration camps. He was known for good organisational skills and for selecting highly competent subordinates, such as Reinhard Heydrich in 1931. From 1943 onwards, he was both Chief of German Police and Minister of the Interior, overseeing all internal and external police and security forces, including the Gestapo (Secret State Police). H ...
