Projectors: LCD Verses DLP (The downfall of DLP technology)

The common question that is asked when buying a new projector for the home, office, or classroom is: do I purchase an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two most common projector imaging technologies. With so many different brands and models available, it can be difficult for customers to pick between those technologies. The simple fact of the matter is that LCD projectors give far superior image quality and colour accuracy. The next paragraph will tell you why DLP projectors struggle with bringing up a similar level of image quality.

Visualise a set of blinds in your home covering your bedroom window. By pulling a rod you can make the shutters open or closed, according to if you want to let light in or not. This is exactly how an LCD projector functions. Each pixel operates like an individual shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as the experts like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from when the projector switches on to when the content reaches your screen is ultimately important in regard to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by splitting it into red, blue and green components, by three mirrors which project the coloured light to 3 stand alone LCD panels. The 3 LCD panels cast the elements of the image by switching each pixel on and off. The pixels are then combined in a glass prism to create the projector image. An important point to realise about LCD projectors is that all three colours are projected onto your screen at once. The way a DLP projector runs is very different and even the final product of how an image looks is not the same. With DLP, white light from the lamp is directed through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of projecting an image requires a sequence of red, blue and green light. The millions of micro mirrors described above reflect the coloured light on the pixels to produce the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s vision will then draw each coloured element of the image into the single complete image. From LCD projectors, all colours are available all the time to deliver high brightness and great colour accuracy. In DLP, just one colour is available at any given time, resulting in lower colour brightness and accuracy. Some manufacturers have placed a white segment into the colour wheel to improve all over brightness, but this then damages colour accuracy.

I see in forums all the time that DLP offers a higher contrast ratio and therefore must be better quality. For those who are unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the projector is capable of producing. DLP projectors do provide high contrast specifications in comparison to the majority of LCD projectors. At first glance, this must be a plus, however, in the real world, the true black level is determined by the ambient light in the room when the projector is in use. Do not be fooled by contrast specifications on websites and in brochures.

When the content you want to see needs moving images, DLP projection technology can also create image marks, or ‘artifacts’. The most common artifact that a DLP projector displays with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images change up between the time red, blue and green colours are pulled up. LCD projectors do not have this problem because all colours are delivered simultaneously. DLP designers have come up with 3DLP solutions using 3 chips to resolve the colour break up artifacts, but the expense of these projectors make them almost impossible for the large part of businesses and consumers.

Another point of difference between LCD and DLP is how they compensate for the refractive qualities of light. Take yourself back to high school science, and recall how different colours of light refract various amounts when directed through the same lens. The disadvantage with DLP projectors is that they use the one same panel with the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light in a different way. Often with a DLP projector, some extra yellow colour will come through above and a spill of blue will come up below an image as simple as a lone black line. While being built LCD projectors can be fixed to take away these effects on the projected image, as each colour is projected on separate LCD panels.

The isolated real plus (excluding price) with deciding on a DLP projector is its smaller overall size and weight. However, this is only relevant to portability and cannot be traded off against the image plusses of LCD projectors. If overall picture quality is vital to you, then the decision is easy. Take an LCD projector! LCD projectors will constantly produce bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch came to preeminence in sea power during the 17th century, the early yacht became a leisure craft used first by royalty and then by the burghers for the canals and then in the protected and unprotected waters of the Low Countries. Racing was incidental, borne from private challenges. English yachting started with King Charles II of England during his exile in the Low Countries. On his return to the English royalty in 1660, the city of Amsterdam sent him a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he then named Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), ordered for more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 bet. Yachting became popular among the wealthy and nobility, but after that time the trend did not last.

The first yacht association in the British Isles, the Water Club, was formed around about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, and had large naval panoply and formality. The closest thing to racing boats was the “chase,” for which the “fleet” pursued a fictional enemy. The club endured, largely as a social club, until 1765, and in 1828, by conglomerating with other clubs, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some ordered fashion on the Thames about the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV rose to sovereignty in 1820, it was named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been formed at Cowes on the Isle of Wight in 1815, and royal funding made the Solent – the strait between the mainland and the Isle of Wight – the continued location of British racing. The club at Cowes became the Royal Yachting Club, also at the ascension of George IV. Each member was required to own boats of at least 20 tons (20,321 kg). Sailing tests for great bets were held, and the club life was lovely. It came to be that the Royal Yachting Club boats increased in size to over 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and continued when the English took power. Sailing was mostly for fun and rose to its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a standard of luxury and elegance for the later yachts in that area from the late 19th century. The first persisting American yacht association, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens began the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts were within the style of such naval craft as brigantines, schooners, and cutters from the 17th century until the second half of the 19th century. The craft of large yachts was initially greatly put upon by the win of America, which was designed by George Steers for a group started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its victory at Cowes in 1851. The first yachts were not designed and built in a contemporary sense, with merely a model for an outline. Not until the latter half of the 19th century did what was called naval architecture come into action. Not until the 1920s did the use of the study of aerodynamics do for the structure of sails and rigging what such science had already done for hulls.

Because most of all sailboats had been individually built, there arose a need for handicapping boats as this was previous to the one-design class boats were built. Thus, a rating rule was created, which resulted in the International Rule, accepted in 1906 and amended in 1919. Today, one of the fastest growing areas in sailing is that of one-design class boats. All boats in a one-design class are created to the same dimensions in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing for these boats can be held on an even par with no handicapping required. A perfect example is the generic International America’s Cup Class taken on for yachts in the 1992 America’s Cup race.

For the time that yachting was done largely for the aristocracy and the wealthy, cost was no object, and the size of boats grew, in both length and weight. The ascendancy and popularity of smaller boats came in the latter half of the 19th century in the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A voyage around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of small boats. Thereafter in the 20th century, particularly after World War II, smaller racing and leisure craft became more popular, down to the dinghy, a preferred training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, at which point steam began to emulate sail power in market craft, the steam engine, and later the internal-combustion engine, were increasingly favoured in leisure boats. Sizeable power yachts were progressed to a high degree, and long-distance travel was a preferred activity of the wealthy. The first power yachts were paddle-wheel boats; they then gave way to those powered by the wholly submerged screw or propeller kind of propulsion. As well as naval and merchant vessels, auxiliaries carrying both sail and power were the yacht fashion for several years. By the latter half of the 20th century, many yachts were still auxiliaries, but the larger part were solely power yachts that had gasoline or diesel engines.

In the last decade of the 19th century there was a boom in the design of large steam yachts. Conspicuous of these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of more than 150. The Mayflower, purchased by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and was used in active service for World War II.

As larger and better quality internal-combustion engines were created, many large boats were using them for power. The development of the diesel engine, with heavy oil for fuel, progressed in World War I. In the decade following that, big power-yacht building blossomed, reaching a climax in the Orion (1930) at 3,097 tons. During that point the best auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of bigger power craft declined from 1932, and the trend thereafter was in preference of smaller, less costly craft. Following World War II, a lot of small naval vessels were traded by private owners for conversion to yachts. At the late 20th century, yachting has become a internationally beloved sport enjoyed by thousands of yachtsmen who are actually owning and maintaining their own small pleasure boats. The popularity of craft and owners increased steadily, not only in the traditional places along the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are distinguished by the effect they have on the distribution of income and wealth. A proportional tax is a tax that applies the same relative onus on all taxpayers—i.e., where tax liability and income grow in relative proportion. A progressive tax is characterized by a larger than proportional increase in the tax onus in relation to the growth in income, and a regressive tax is recognisable by a less than proportional increase in the comparable liability. Therefore, progressive taxes are seen as taking away a lack of equality in income distribution, while regressive taxes can have the effect of increasing these inequalities.

The taxes that are often considered progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, can become less so for the upper-income categories—especially if a taxpayer is able to lessen his tax base by nominating deductions or by excluding certain income elements from his taxable income. Proportional tax rates when applied to lower-income classes would also be more progressive if such personal exemptions are made.

Income measured over a given period does not necessarily provide the most accurate measure of taxpaying ability. For example, transitory rises in income may be saved, and within temporary declines in income a taxpayer could opt to finance consumption by taking from savings. Ergo, if taxation is regarded along with “permanent income,” it can be less regressive (or more progressive) than when it is made comparable with annual income.

Sales taxes and excises (save those on luxuries) are usually regressive, because the portion of own income consumed or spent on a specific good declines as the rate of personal income increases. Poll taxes (also called head taxes), levied as a standard amount per capita, patently are regressive.

It is not easy to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to the uncertainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden lays for the most part on whether a national or a subnational (that is, provincial or state) tax is being debated.

In regarding the economic purpose of taxation, it is essential to differentiate between differing ideas of tax rates. The statutory rates include those dictated in law; usually these are marginal rates, but sometimes they are median rates. Marginal income tax rates signify the fraction of incremental income taken by taxation when income grows by one dollar. So, if tax onus grows by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax statutes usually contain graduated marginal rates—i.e., rates that rise as income increases. Structured analysis of marginal tax rates are required to take into account provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lowers by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points higher than specified within the statutory rates. Since marginal rates signify how after-tax income is changed in response to changes in before-tax income, they are the appropriate ones for regarding incentive effects of taxation. It is even more difficult to realise the marginal effective tax rate to apply to income from business and capital, since it may be dependant on considerations such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem holds that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates determine the percentage of total income that is taken in taxation. The pattern of average rates is the one that is necessary for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates generally grow with income, both because personal allowances are granted for the taxpayer and dependents and also due to that marginal tax rates are graduated; on the other side of things, preferential treatment of income received fundamentally by high-income households could dwarf these effects, producing regressivity, as indicated by average tax rates that decrease as income rises.

The Development of Data Projectors

The LCDs utilised for projection systems are generally small reflective or transmissive panels lit by a strong arc lamp source. A line of lenses expands the reflected or transmitted image then casts it on the screen. For front-projection systems the LCD is located on the side of the screen as the viewer, however in rear-projection systems the screen is lit up from behind. Projectors of more expense and performance may use three distinct LCD panels, casting separate red, green, and blue images that come together to reflect a coloured picture on the screen.

The growth in desire for film displays has granted a growing emphasis on the switching speed of liquid crystals. This has necessitated the creation of objects utilizing smectic liquid crystals, particular types of which possess a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most developed smectic device. Inside it the liquid crystal molecules are set out in layers that are perpendicular to the substrate planes, which are separated by one or two micrometres, and inside the layers the molecules are tilted, as shown in the figure. The host liquid crystal possesses optically active molecules, and a minor outcome of the optical activity and the shape of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, comparable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and within the plane of the layers. So, there is a permanent charge separation through the liquid crystal layer in the SSFLC, and its sign is directly partnered to the tilt direction of the molecules. An applied voltage of the correct sign can reverse the direction of this dipole in tens of microseconds and hence reverse the tilt direction of the molecules. The consequential change in optical properties can effect a change from light to dark in the case that one or more polarizers are employed.

SSFLC devices have been commercialized for bigger passive-matrix presentations, but their high cost and complexity has stopped them from creating any significant impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some possibility for use as aspects in projection systems or as viewfinders in digital cameras. Their fast responding allows them to be used in time-sequential colour systems, in which highly expensive colour filters are replaced with a coloured backlight that flashes red, green, and blue in rapid pace (about 100 cycles per second). For example, the liquid crystal could be switched to a transmissive state between the red and green periods but then to a nontransmissive state in the blue period, creating the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From all the furniture objects, the chair may be of the most importance. While the majority of other items (except the bed) are designed to support objects, the chair supports the human form. The term chair was used here in the most open sense, from stool to throne to derivative pieces for example a bench and sofa, which may be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently distinguished.

The social history of the chair is as curious as its history as art and craft. The chair is not just a physical support and/or aesthetic creation; it is also semiotic of social rank. At the historical royal courts there were important connotations between sitting on a chair with arms, sitting on a chair with a back but without arms, or worse having to use a stool. Since the last century, the director’s and manager’s chair has developed an identifier of superior standing, and even in democratic government meeting the speaker sits on a raised floor.

In its furniture purpose, the chair is employed for a variety of variations. There are chairs created to match man’s age and physical abilities (the high chair, the wheelchair) and to denote his position in society (the executive chair, the throne). From past days there were chairs for births (birth chairs); during the 20th century, there have been chairs used to die in (the electric chair). We make chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. We can have chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Modern day living has developed particular chairs for automobiles and aircraft. Every one of these chair forms have been adapted to fit to different human requirements. Due to its close relationship with man, the chair lives to its full significance only when being utilised. Whereas it doesn’t make a difference to one’s appreciation of a cupboard or a dresser drawers if there are things inside or not, a chair is seen best and evaluated by a person sitting in it, for chair and sitter need each other. Thus the various areas of a chair have been given labels likened to the areas of the human parts: arms, legs, feet, back, and seat.

Because the principal job of the chair is to support our human body, its worth is tested principally from how suitably it fulfills this practical purpose. In the manufacture of a chair, the chair maker is limited within some static regulations and principal measurements. Under these rules, however, the chair maker has extensive freedom.

The history of the chair covers dates of several thousand years. There is evidence of civilizations that made iconic chair shapes, seen of the premier object in the arenas of skill and aesthetics. Among these such peoples, individual mention needs to be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the construct of expert make, are seen from tomb discoveries. The first of these two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have had four legs crafted similar to those of a chosen animal, a curved seat, and leading to a sloping back supported over vertical stretchers. In this design a strong triangular design was made. There was in our view no particular change in the design of Egyptian thrones and chairs for ordinary citizens. The simple change exists in the intricacy of its ornamentation, in the evidence of pricey inlays. The Egyptian folding stool probably was manufactured for an easily stored seat for army soldiers. As a camp stool this kind continued during much later times. But the stool also then took on the character of a ceremonial seat, its original role as a folding stool being forgotten. This can today be found, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are made in the structure of folding stools but can’t be folded because the seats are created with wood. The plain structure of the folding stool, consisting of two frames that cycle on metal bolts and support a seat of leather or fabric secured between them, appeared somewhat later during the Bronze Age folding chairs of Scandinavia and northern Germany. The most well known of those is the folding stool, made from ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is seen not as any ancient object still existing but seen in a wealth of pictorial material. The most well known is the klismos depicted on the Hegeso Stele at the Dipylon burial place by Athens (c. 410 BC). This klismos is a chair with a backward-sloping, curved backboard and four curving legs, but only two of these legs are shown. These unique legs were presumed to be crafted of bent wood and were probably bore a large amount of pressure with the weight of the sitter. The joints attaching the legs to the frame of the seat had to be therefore very solid and were visibly pointed out.

The Romans borrowed from the Greek designs; a number of casts of seated Romans are chairs of a heavier and are a somewhat crudely built klismos. Both designs, the light and the heavy, were revived during the Classicist period. The klismos style can be seen in French Empire styles, in English Regency, and in some particular types of considerable individuality within Denmark and Sweden during 1800.

China
The ancestry of the chair in China is not able to be followed as far back as in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an unscathed serial of images and paintings had been kept, detailing the insides and outer parts of Chinese households and the designs of furniture. Also kept of the 16th century are a collection of chairs constructed of wood or lacquered wood, that possess an interesting familiarity to styles of older chairs.

Just as in Egypt, there were two standard chair forms in China: a chair that had four legs and a folding stool. That chair is designed both with or without arms although never missing its square seat and straight stiles (vertical side supports) to hold up the back. In one style, it has been seen, the stiles were marginally curved by the arms to sit right with the angle of the S-shaped back splat (the centre upright of a chairback). All three limbs had been mortised onto the yoke-like top rail. Despite that the design of the back splat later had an introduction for English chairs from the Queen Anne period, wooden members that only to a particular extent reinforce corner joints (and then are loose into the bargain) indicate an element signatory to Chinese chairs. The four legs sit through the seat frame, which stops about the rounded staves. Members are round in section or is given rounded edges—an acknowledgement perchance to the bamboo tradition. The seat is uncomfortable and occasionally had a plaited seat. These chairs required of the sitter to remain stiff and upright; for if too much weight is pushed on the back, the chair has a habit of falling over. In patriarchal Chinese homes of this era armchairs probably were kept for elderly family members, for they were given great respect.

The Chinese folding stool is believed to have travelled to China from the West. It does not vary that much from the Egyptian or Scandinavian folding stools, but it has a change in that the top rail is prettily affixed to the two legs of the stool by means of a curved member, which is often possessing metal mounts. From a Western viewpoint the resulting effect of both furniture forms is stylized. The manufacture and decoration issues are combined in a manner that is all at once both naïve and refined. The patchwork appearance is a result of the way that the individual parts do not look to have been joined together by either glue or screws, but are mortised onto one another and locked into position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also had its name on the chair. Paintings show a kind of chair with a relatively unrefined wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing in between, stitched to bring up a pattern of little pads. The front board and a similar board at the back could be folded after loosening some small iron hooks. In this way the chair was a readily portable piece of furniture in traveling which, at the same era, had the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair can be evidenced in engravings of the inside of rich Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this design of chair might also be seen in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not decided that the form actually originated in The Netherlands. Usually, the legs of the chair were smooth, round in section, and of slender measurements; they are sometimes baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was made in large numbers, as indicated from one of Abraham Bosse’s engravings, in which there is a whole row of this kind of chairs lined up along a wall. The style asserts itself with its shapely proportions and fine upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that is to say, as developed in Paris around 1750—disseminated over most of Europe and has been imitated or copied in the mid-20th century. The style owes such popularity to a combination of comfort and delicacy. The seat conforms to the human body and grants a relaxed sitting position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are small upholstered pads on the armrests. Smooth transitions achieved between seat frame, legs, and back disguise all the joints, which are stable, constructed on craftsmanlike methodology despite the absence of stretchers between the legs.

French Rococo chairs and imitations of those have wood of rather thick density; but every member is deeply molded, all superfluous wood has been removed, and finer examples can be further embellished with very delicate and decorative woodwork. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for any upholstery on the seat, back, and armrests; cane is sometimes used in place of upholstery.

English chairs in the 18th century were more differentiated in style than the French. The French taste for stylistic uniformity, which lead from the premier circles in Paris and Versailles within most of France and won favour in several parts of the Continent, had no parallel in England. Prior to 1740, the most commonly used wood was walnut; thereafter, and for the rest of the century, it was mahogany. Walnut, though beautiful in hue, was soft and therefore less suited to wood carving than to rounded, curving forms. Outer surfaces, such as the back and seat frame, were usually veneered. During the walnut period, highly overstuffed armchairs, covered with leather or embroidered material, were also developed. The best upholstery of this period is precisely and firmly modelled and accentuated by braiding or tacks. When imports of mahogany became common, no specifically new chair designs appeared, but the character of the woodwork changed. Mahogany, having a firmer, closer grain, could be cut thinner, which meant that individual parts of the chair could be more slender in shape. Mahogany also lent itself better to carving than walnut. Carving was concentrated more on the arms and back than on the legs, which as a rule were straight and smooth with chamfered (bevelled) edges and molding. There was a wealth of variety in chairback designs, featuring elegant, pierced, vase-shaped splats or two upright posts connected by horizontal slats (ladderback).

Alongside the French Rococo chair and the best English chairs in walnut and mahogany, the stick-back chair was relatively unaffected by the stylistic changes of the day. Originally a medieval form, known, for example, from paintings by Pieter Bruegel the Elder and still found in mid-20th century in the churches and inns of southern Europe, the stick-back chair (in all of its variations) consists basically of a solid, saddle-shaped seat into which the legs, back staves, and possibly the armrests are directly mortised. This typically peasant form underwent a renewal and a process of refinement in England and America during the 18th century. Under the name Windsor chair (a term that seems to have been used for the first time in 1731) or Philadelphia chair, it became popular and was widely distributed throughout the world.

Late 18th to 20th century
During the Neoclassical period, no basic changes took place in chair forms, but legs became straight and dimensions lighter. Backs in the shape of classical vases replaced the fanciful outlines of the Rococo period. Around 1800, freely executed imitations of Greek and Roman chairs of the klismos type, with curved legs and backrest, appeared. French chairs of the Empire period, executed in dark mahogany and embellished with ornate bronze mounts, created a ponderous effect.

In cheaper brands of inferior workmanship, bourgeois chairs of the 19th century carried on the traditions of the 17th and 18th centuries. The only real innovations were the bentwood (wood that has been bent and shaped) chairs in beech that became popular all over the world and were still made in the 20th century. Around 1900 the continental Art Nouveau and Jugendstil styles (French and German styles characterized by organic foliate forms, sinuous lines, and non-geometric forms), and the Arts and Crafts movement in England (established by the English poet and decorator William Morris to reintroduce idealized standards of medieval craftsmanship), gave rise to original chair designs by Eugène Gaillard in France, Henry van de Velde in Belgium, Josef Hoffman in Austria, Antonio Gaudí in Spain, and Charles Rennie Mackintosh in Scotland. These new furniture styles did not exercise wide, let alone decisive, influence. The Art Nouveau chairs designed by the French architect Hector Guimard, for example, are collector’s pieces, but his name is known to a broader public only because of his fanciful entrances to the Paris Métro.

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, hint that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recordkeeping of the money values of the function of a business. Bookkeeping gives the details from which accounts are written but is a different process, prior to accounting.

Essentially, bookkeeping provides two parts of information: (1) the current value, or equity, of the business and (2) the changes in value—profit or loss—taking position in the business from a given period of time.

Management officials, investors, and credit grantors all need such information: management to understand the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to analyse the outcome of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors so as to regard the financial statements of an entity in assessing whether to allow a loan.

Evidence of financial and numerical recordkeeping have been seen for almost every state with a commercial background. Records of commercial contracts have been found in the archaelogical digs of Babylon, and accounts for both farms and estates had been archived in ancient Greece and Rome. The two-entry manner of bookkeeping came up with the development of the business republics of Italy, and tutorials for bookkeeping were created in the 15th century in several Italian cities.

In the late 18th and early 19th centuries, the Industrial Revolution provided a notable stimulus to accounting and bookkeeping.

The development of manufacturing, trading, shipping, and subsidiary services made perfect financial books a requirement. The ancestry of bookkeeping, in fact, closely reflects the ancestry of commerce, industry, and government and, in part, assisted in forming it. The global spread of industrial and commercial activity needed more cosmopolitan decision-making processes, which itself called for more sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government legislature became more important and resulted in even greater demand for information; entities had to have available information to go with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the requirement for bookkeeping for their own departmental operations became higher.

Although bookkeeping methods can be very complex, all are based on two types of books utilised in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, etcetera), and the ledger has the details of individual accounts. The daily records from the journals are put in the ledgers.

At the end of each month, by general practice, an income statement and a balance sheet are prepared from the trial balance posted out of the ledger. The point of the income statement or profit-and-loss statement is to provide an analysis of those changes that took place in the enterprise equity due to the transactions of the period. The balance sheet provides the financial position of the corporation at a particular point in time in terms of assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

The invention of jet propulsion was ideal for fighter aircraft. Although at first it reduced range and endurance and often increased the take-off run. The German Messerschmitt Me 262 and the British Gloster Meteor twin jets saw action in 1944, together with the tailless Me 163 rocket interceptor which sacrificed range and endurance for astounding climb and speed in defending local areas against heavy bombers.

Germany was far in front of other countries in another factor too: armament. A range of 30 mm (1 inch) cannon, radically new high-speed cannon with multiple-revolver chambers, very large recoilless guns, spin-stabilised air-to-air rockets fired in salvoes, and wire-guided air-to-air missiles were all under test before the Luftwaffe s defeat. They gradually inspired similar developments in other countries: one German gun, the Mauser MG 213, led to the American Pontiac M-39, the French DEFA, the Russian NR-30, the Swiss Oerlikon KCA, and the British Aden, all of which are still in use.

Many early jet fighters were fitted into more or less conventional airframes. The fighter often considered the ultimate achievement of the piston era, the long-range North American P-51 Mustang appeared both in a twinned double-fuselage form and, with few changes, as a US Navy jet.

But the US Air Force decided to wait a year until its makers could sweep back the wings and tail at 35 degrees, which German research had shown could lead to higher speed. The result was the F-86 Sabre, which in 1948 set a speed record at 1,080 km/h (671 mph) and outflew all other fighters. Later versions carried radar and rockets and reached 1,150 km/h (715 mph).

During the Korean War (1950-3) the F-86 met a previously unknown machine built in the Soviet Union, the somewhat lighter and simpler MiG-15, and although the MiG could climb higher and had heavy cannon, the Sabre’s skilled pilots and better equipment gave it the edge in combat.

North American’s next fighter was the F-100 Super Sabre, which exceeded the speed of sound in level flight. The MiG bureau built the twin jet MiG-19, which was even faster, and is still in wide use. The US Air Force ordered various all-weather interceptors with largely automatic radar and flight control systems so that, with guided missiles, they could intercept and destroy enemy aircraft without the pilot ever seeing them.

The British ordered a jet-fighter flying-boat, but discovered that this way of doing business without airfields yielded an inferior fighter. The Americans suffered similar problems with a ‘hydroski’ fighter, which could dive faster than sound, but took off and landed on retractable water skis.

Two even stranger fighters were designed around powerful turboprop engines and, standing on their tails, screwed themselves vertically into the air (they were intended to operate from the confined decks of warships or merchant vessels). Britain built high-altitude supersonic fighters with ‘mixed power’ from a turbojet and a rocket. In 1957 the British Minister of Defence suggested there would soon be no more manned fighters at all, only missiles. The Americans stuck to fighters, but made them very large and armed them with missiles, but no gun.

Today the wheel has turned full circle. In the past 10 to 20 years there has been a powerful trend to get back to the ‘eyeball-to-eyeball’ type of confrontation of the man in the Sopwith Camel. The pre-eminent Western fighter, the McDonnell Douglas F-4 Phantom, was rebuilt with an internal gun, a rapid-fire 20 mm (0.79 in) cannon with six barrels firing up to 6,000 rds/ min, and a slatted wing to pull tighter turns in combat.

New small fighters appeared, such as the General Dynamics F-16, which, although bigger and heavier than any single-engined fighters of World War II, are nevertheless small and light by comparison with such impressive machines as the Grumman F-14 Tomcat, McDonnell Douglas F-15 Eagle, and MiG-25 Foxbat, The RAF’s next interceptor, the ADV (Air-Defence Version) of the Panavia Tornado, is a careful midway compromise, smaller than the three monsters just listed, but with two engines, long range, powerful radar, and extremely effective Skyflash missiles.

Modern interceptors defend vast blocks of airspace up to 160 km (100 miles) in radius, with powerful radar able to look down at the surrounding land and water and spot low-flying intruders trying to slip through the defences unnoticed. Their task is eased by the presence of special surveillance, early-warning, and AWACS (Airborne Warning and Control System) aircraft, with enormous radars and sophisticated command and control systems to manage all a nation’s defences in the most efficient way.

There is no better feeling than being in the cockpit during your jet fighter flight. Jet fighter flights and jet fighter joy flights are the ultimate gift giving and receiving experience that will be remembered forever.
