Orthopedic cast

An orthopedic cast, body cast, plaster cast, or surgical cast, is a shell, frequently made from plaster or fiberglass, encasing a limb (or, in some cases, large portions of the body) to stabilize and hold anatomical structures, most often a broken bone (or bones), in place until healing is confirmed. It is similar in function to a splint.

Plaster bandages consist of a cotton bandage that has been combined with plaster of paris, which hardens after it has been made wet. Plaster of Paris is calcined gypsum (roasted gypsum), ground to a fine powder by milling. When water is added, the more soluble form of calcium sulfate returns to the relatively insoluble form, and heat is produced.

The setting of unmodified plaster starts about 10 minutes after mixing and is complete in about 45 minutes; however, the cast is not fully dry for 72 hours.

Nowadays bandages of synthetic materials are often used, often knitted fiberglass bandages impregnated with polyurethane, sometimes bandages of thermoplastic. These are lighter and dry much faster than plaster bandages. However, plaster can be more easily moulded to make a snug and therefore more comfortable fit. In addition, plaster is much smoother and does not snag clothing or abrade the skin.

Cast (gymnastics)

A cast is a basic skill on uneven bars in artistic gymnastics. From the front hang, a gymnast pikes (allowing the knee to touch the bar) and slides upwards to a handstand. Some gymnasts may perform the move with straddled legs. It is an "A" move in the Code of Points.

Fossil

Fossils (from Classical Latin fossilis; literally, "obtained by digging") are the preserved remains or traces of animals, plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record.

The study of fossils across geological time, how they were formed, and the evolutionary relationships between taxa (phylogeny) are some of the most important functions of the science of paleontology. Such a preserved specimen is called a "fossil" if it is older than some minimum age, most often the arbitrary date of 10,000 years. Hence, fossils range in age from the youngest at the start of the Holocene Epoch to the oldest, chemical fossils from the Archaean Eon, up to 3.48 billion years old, or even older, 4.1 billion years old, according to a 2015 study. The observation that certain fossils were associated with certain rock strata led early geologists to recognize a geological timescale in the 19th century. The development of radiometric dating techniques in the early 20th century allowed geologists to determine the numerical or "absolute" age of the various strata and thereby the included fossils.

The Times

The Times is a British daily national newspaper based in London. It began in 1785 under the title The Daily Universal Register and became The Times on 1 January 1788. The Times and its sister paper The Sunday Times (founded in 1821) are published by Times Newspapers, since 1981 a subsidiary of News UK, itself wholly owned by the News Corp group headed by Rupert Murdoch. The Times and The Sunday Times do not share editorial staff, were founded independently and have only had common ownership since 1967.

In 1959, historian of journalism Allan Nevins analysed the importance of The Times in shaping the views of events of London's elite:

The Times is the first newspaper to have borne that name, lending it to numerous other papers around the world, including The Times of India (founded in 1838), The Straits Times (Singapore) (1845), The New York Times (1851), The Irish Times (1859), Le Temps (France) (1861-1942), the Cape Times (South Africa) (1872), the Los Angeles Times (1881), The Seattle Times (1891), The Manila Times (1898), The Daily Times (Malawi) (1900), El Tiempo (Colombia) (1911), The Canberra Times (1926), and The Times (Malta) (1935). In these countries, the newspaper is often referred to as The London Times or The Times of London.

Times New Roman

Times New Roman is a serif typeface commissioned by the British newspaper The Times in 1931 and created by Victor Lardent in collaboration with the British branch of the printing equipment company Monotype. Although no longer used by The Times, Times New Roman is still very common in book and general printing. Through distribution with Microsoft products and as a standard computer font, it has become one of the most widely used typefaces in history.

Times New Roman's creation took place through the influence of Stanley Morison of Monotype. Morison was an artistic director at Monotype, historian of printing and informal adviser to the Times, who recommended that they change typeface from the spindly and somewhat dated nineteenth-century Didone typeface previously used to a more robust, solid design, returning to traditions of printing from the eighteenth century and before. This matched a common trend in printing of the period.

Morison proposed an older Monotype typeface named Plantin as a basis for the design, but revisions were made to increase legibility and economy of space. The new font was drawn by Victor Lardent, an artist from the advertising department of The Times, with Morison consulting, before refinement by the experienced Monotype drawing office team.The new design made its debut in the 3 October 1932 issue of The Times. After one year, the design was released for commercial sale. The Times stayed with Times New Roman for 40 years, but new production techniques and the format change from broadsheet to tabloid in 2004 have caused the newspaper to switch typeface five times since 1972. However, all the new fonts have been variants of the original New Roman typeface.

Multiplication sign

The multiplication sign or times sign is the symbol ×. The symbol is similar to the lowercase letter x but is a more symmetric saltire, and has different uses. It is also known as St. Andrew's Cross and dimension sign.

Uses

In mathematics, the symbol × (read as times or multiplied by) is primarily used to denote the

In biology, the multiplication sign is used in a botanical hybrid name, where it is read as "cross".

The multiplication sign is also used by historians for an event between two dates. When employed between two dates, for example 1225 and 1232, 1225×1232 means "no earlier than 1225 and no later than 1232". It can also be used in a date range: 1225×1232–1278.

History

The × symbol for multiplication was introduced by William Oughtred in 1631. It was chosen for religious reasons to represent the cross.
