Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...

Cell (biology)
The cell is the basic structural and functional unit of life forms. Every cell consists of a cytoplasm enclosed within a membrane, and contains many biomolecules such as proteins, DNA and RNA, as well as many small molecules of nutrients and metabolites.Cell Movements and the Shaping of the Vertebrate Body

List Of S&P 500 Companies
The S&P 500 stock market index is maintained by S&P Dow Jones Indices. It comprises 503 common stocks which are issued by 500 large-cap companies traded on American stock exchanges (including the 30 companies that compose the Dow Jones Industrial Average). The index includes about 80 percent of the American equity market by capitalization. It is weighted by free-float market capitalization, so more valuable companies account for relatively more weight in the index. The index constituents and the constituent weights are updated regularly using rules published by S&P Dow Jones Indices. Although called the S&P 500, the index contains 503 stocks because it includes two share classes of stock from 3 of its component companies.

Laboratory Equipment
A laboratory (; ; colloquially lab) is a facility that provides controlled conditions in which scientific or technological research, experiments, and measurement may be performed. Laboratory services are provided in a variety of settings: physicians' offices, clinics, hospitals, and regional and national referral centers. Overview The organisation and contents of laboratories are determined by the differing requirements of the specialists working within. A physics laboratory might contain a particle accelerator or vacuum chamber, while a metallurgy laboratory could have apparatus for casting or refining metals or for testing their strength. A chemist or biologist might use a wet laboratory, while a psychologist's laboratory might be a room with one-way mirrors and hidden cameras in which to observe behavior. In some laboratories, such as those commonly used by computer scientists, computers (sometimes supercomputers) are used for either simulations or the analysis of data. Scien ...

Magazine
A magazine is a periodical publication, generally published on a regular schedule (often weekly or monthly), containing a variety of content. They are generally financed by advertising, purchase price, prepaid subscriptions, or by a combination of the three. Definition In the technical sense a ''journal'' has continuous pagination throughout a volume. Thus '' Business Week'', which starts each issue anew with page one, is a magazine, but the '' Journal of Business Communication'', which continues the same sequence of pagination throughout the coterminous year, is a journal. Some professional or trade publications are also peer-reviewed, for example the '' Journal of Accountancy''. Non-peer-reviewed academic or professional publications are generally ''professional magazines''. That a publication calls itself a ''journal'' does not make it a journal in the technical sense; ''The Wall Street Journal'' is actually a newspaper. Etymology The word "magazine" derives from Arabic , ...

Edward Troughton
Edward Troughton FRS FRSE FAS (October 1753 – 12 June 1835) was a British instrument maker who was notable for making telescopes and other astronomical instruments. Life Troughton was born at Corney, Cumberland, the youngest of six children to Francis Troughton, a husbandman on a farm, and his wife, Mary Stable. Originally raised to tend animals, Edward went to London in 1773. He then served an apprenticeship with his uncle, John Troughton (b.c.1716) alongside his elder brother, also John Troughton, and in 1779 he became his business partner and soon established himself as the top maker of navigational, surveying and astronomical instruments in Britain. They were based at 136 Fleet Street in central London. Their shop was called the "Sign of the Orrery". In 1795 he delivered what is now known as the Troughton Equatorial telescope to the Armagh Observatory, a 2-inch aperture refractor telescope mounted equatorially, and its first major instrument since its founding in 179 ...

Troughton & Simms
Troughton & Simms was a British scientific instrument firm. It was formed when Edward Troughton in his old age took on William Simms as a partner in 1826. It became a limited company in 1915 and in 1922 it merged with T. Cooke & Sons to form Cooke, Troughton & Simms. The firm had its origins in the instrument-making business begun in 1764 by John Troughton (1716-1788). This business was successively passed down first to nephews, John Troughton (1739-1807) and then to Edward Troughton (1756-1835). In 1826 Edward Troughton took on William Simms as partner. Origins In 1756, John Troughton Senior from Corney, Cumberland, set up business in London, having completed his apprenticeship with London instrument maker Thomas Heath. In 1769, his nephew John Troughton Junior, after completing his apprenticeship with his uncle, set up in business for himself. He took over the business of Benjamin Cole in 1782, a maker of orreries at a shop in Fleet Street called "At the Sign of The O ...

Thomas Cooke (machinist)
Thomas Cooke (8 March 1807 – 19 October 1868) was a British scientific instrument maker based in York. He founded T. Cooke & Sons, the scientific instrument company. Life Thomas Cooke was born in Allerthorpe, near Pocklington, East Riding of Yorkshire, the son of James Cook (a shoemaker). His formal education consisted of two years at an elementary school (possibly the school of John Whitaker, also of Allerthorpe), but he continued learning after this and he taught himself navigation and astronomy with the intention of becoming a sailor. His mother dissuaded him from that career and he became a teacher. He made such a success of being an impromptu teacher to the farmers’ sons of the Pocklington district, that only a year later he was able to open a village school at Bielby. He continued to teach others by day and learn himself by night, and soon moved his school from Bielby to Skirpenbeck. At Skirpenbeck he met his future wife, who was one of his pupils, and five years ...

Cooke, Troughton & Simms
Cooke, Troughton & Simms was a British instrument-making firm formed in York in 1922 by the merger of T. Cooke & Sons and Troughton & Simms. Origins Thomas Cooke set up a business in York in 1837 making astronomical telescopes. One early notable instrument was a 4.5 inch equatorial refractor which would have been exceptional at the time. In 1851 Cooke built a 7.25 inch equatorial telescope. Cooke made the optical elements himself for both these instruments. Thomas Cooke built a reputation for high quality optics and, as well as smaller instruments, supplied large instruments to observatories around the world. From the outset in 1826 and earlier Troughton and Simms of London excelled in the high precision work of dividing circles and so provided many observatories with large transit instruments and supplied national surveys such as the Ordnance Survey, with large transit theodolites. Merger In 1922 with business in a depressed state Cooke and Troughton & Simms merged with head o ...
