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

The typical question that is asked when looking for a new projector for the home, office, or classroom is: do I purchase an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two most popular projector imaging technologies. With so many different brands and types available, it can be challenging for customers to pick between those technologies. The fact is that LCD projectors give better image quality and colour accuracy. The next part of this article explains why DLP projectors struggle with projecting a similar grade of image quality.

It’s like a set of blinds in your house for your bedroom window. By pulling on a rod you can turn the shutters open or closed, depending on if you want to let light in or not. And such is exactly how an LCD projector works. Each pixel functions like a unique shutter on a set of blinds to either send light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as pros like to call them. Each pixel element operates to either reflect light or block it.

How the light source is processed from the time the projector is turned on to when the content reaches your screen is vitally significant with regard to image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by cutting it into red, blue and green components, by three mirrors which transfer the coloured light to 3 stand alone LCD panels. The 3 LCD panels make the elements of the image by shining each pixel on and off. The pixels are then simultaneously processed in a glass prism to send the projector image. A point to remember about LCD projectors is that all three colours are sent onto your projected surface at the same time. The way a DLP projector works is very different and even the final product of how an image shows up is not the same. With DLP, white light from the lamp is processed through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of projecting an image creates a sequence of red, blue and green light. The millions of micro mirrors as described above reflect the coloured light on the pixels to produce the image elements. The elements of the image are projected in sequence on the screen, one colour at a time. The viewer’s eyes will then combine each coloured element of the image into a full image. Using LCD projectors, all colours are available all the time to deliver the best brightness and great colour accuracy. In DLP, only one colour is available at a time, resulting in lower colour brightness and accuracy. Some manufacturers have placed a white segment into the colour wheel to improve overall brightness, but this then detracts from colour accuracy.

I read in forums all the time that DLP has a higher contrast ratio and as such must be superior. For those who are unaware, 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 machine is capable of producing. DLP projectors do offer high contrast specifications as compared to a majority of LCD projectors. At one glance, this appears to be an advantage, however, in truth, the true black level is determined by the ambient light in the room in which the projector is in use. Do not be fooled by contrast specifications on websites and in brochures.

When the content you want to view needs moving images, DLP projection technology can also create image imperfections, or ‘artifacts’. The most commonplace artifact that a DLP projector shows with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images keep changing between the time red, blue and green colours are displayed. LCD projectors do not have this characteristic because the colours are processed at the same time. DLP designers have created 3DLP solutions using 3 chips to fix the colour break up error, but the price tag of these projectors make them hardly practical for most businesses and consumers.

Another differentiation between LCD and DLP is how they compensate for the refractive qualities of light. Jump back to high school science, and remember when they taught you how various colours of light refract differing amounts when directed through the same lens. The downfall with DLP projectors is that they take the one same panel with the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light at different levels. Generally with a DLP projector, some yellow colour will appear above and some extra blue will appear below an image containing something as simple as a straight black line. During manufacturing LCD projectors can be set to minimize these effects on the projected image, as each colour is processed on its own LCD panels.

The isolated true plus (excluding price) with taking a DLP projector is its overall smaller size and weight. However, this is only relevant for transport and has to be traded off against the image superiority of LCD projectors. If resulting picture quality is vital to you, then the solution is no-brainer. Go with an LCD projector! LCD projectors will definitely show bright, colourful images with fewer image imperfections.

Yachting and Yacht Clubs

As the Dutch rose to preeminence in sea power during the 17th century, the early yacht became a pleasure craft used first by royalty and then by the burghers on the canals as well as the protected and unprotected waters of the Low Countries. Yacht racing was incidental, borne from private games. English yachting originated with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English royalty in 1660, the city of Amsterdam sent him a 20-metre (66-foot) leisure 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), made more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 bet. Yachting rose as popular for the rich and aristocracy, but after that period the habit did not last.

The first yacht group in the British Isles, the Water Club, was started at about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, and held much naval panoply and formality. The closest thing to racing was the “chase,” when the “fleet” pursued an imagined enemy. The club went on, for the large part as a social club, until 1765, and in 1828, when joining with other clubs, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some organized manner on the Thames around the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV ascended to monarchy in 1820, it was known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been started at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the continuing location of British yachting. The organisation 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 races for high bets were held, and the social life was splendid. Ultimately Royal Yachting Club boats grew in size to bigger than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and continued when the English gained power. Sailing was mostly for leisure and reached its high point in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and established a minimum of luxury and sophistication for the later yachts in that area from the late 19th century. The first enduring American yacht organisation, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens instigated the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts took the style of such naval craft as brigantines, schooners, and cutters from the 17th century until the later half of the 19th century. The design of bigger 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.) was named after its success at Cowes in 1851. Earlier yachts were not designed and crafted in the modern sense, with just a model used. Not until the latter half of the 19th century did what was labeled naval architecture come into being. Not until the 1920s did the employment of the science of aerodynamics do for the structure of sails and rigging what such study had already done for hulls.

Because almost all sailboats had been individually manufactured, there was a desire for handicapping boats previous to the one-design class boats were made. Thus, a rating rule was created, which resulted in the International Rule, accepted in 1906 and revised in 1919. Today, one of the fastest flourishing areas in the sailing industry is that of one-design class boats. All boats in a one-design class are built to single dimensions in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between those boats can be held on an even keel with no handicapping required. A prime example is the standard International America’s Cup Class adopted for racers in the 1992 America’s Cup race.

For the time that yachting was done mostly for the nobility and the rich, cost was no object, and the size of boats increased, in both length and weight. The ascendancy and preference of smaller boats occurred 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) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of less sizeable yachts. Thereafter in the 20th century, particularly after World War II, smaller racing and recreational boats became more popular, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, in which steam began to take the place of sail power in commercial craft, the steam engine, and later the internal-combustion engine, were favoured increasingly in personal yachts. Bigger power yachts were furthered to a high degree, and long-distance sailing became a favourite activity of the affluent. The early power yachts were paddle-wheel boats; they then gave rise to yachts powered by the wholly submerged screw or propeller sort of propulsion. Like naval and merchant craft, auxiliaries with both sail and power were the yacht standard for a number of years. By the second half of the 20th century, several yachts were still auxiliaries, but the majority were solely power yachts with gasoline or diesel engines.

In the last decade of the 19th century there was a boom in the manufacture of bigger steam yachts. Notably within these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was manned by a crew of more than 150. The Mayflower, commissioned by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and gave active service in World War II.

As larger and more reliable internal-combustion engines were developed, many big craft began using them for power. The development of the diesel engine, employing heavy oil for fuel, was furthered from World War I. In the decade that followed, large power-yacht creation flourished, hitting a climax in the Orion (1930) at 3,097 tons. From that point the biggest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of larger power boats declined after 1932, and the style after that was for smaller, less expensive yachts. From World War II, a lot of small naval craft were traded by private owners for conversion to yachts. In the late 20th century, yachting has become a globally beloved sport enjoyed by thousands of yachtsmen personally sailing and upkeeping their own small pleasure boats. The popularity of yachts and yachtsmen has increased steadily, not only in the traditional locations by the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be distinguished by the effect they have on the placement of income and wealth. A proportional tax is a tax that puts the same relative burden on all taxpayers—i.e., when tax liability and income increase in equal levels. A progressive tax is characterized by a larger than proportional increase in the tax onus in regard to the increase in income, and a regressive tax is recognisable by a less than proportional increase in the comparable onus. So, progressive taxes are seen as taking away inequalities in income distribution, whereas regressive taxes are seen to result in increasing these inequalities.

The taxes that are usually considered progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, can become less so within the upper-income group—especially if a taxpayer is able to lessen his tax base by declaring deductions or by excluding some income aspects from his taxable income. Proportional tax rates which are applied to lower-income groups can also be more progressive if exemptions of a personal nature are made.

Income measured over the course of a given period might not necessarily offer the best measure of taxpaying status. For example, transitory increases in income could be saved, and during temporary declines in income a taxpayer may choose to provide for consumption by reducing savings. Thus, if taxation is made comparable along with “permanent income,” it can be less regressive (or more progressive) than if it is compared with annual income.

Sales taxes and excises (excepting luxuries) are generally regressive, because the portion of one’s income consumed or spent for a specific good declines as the level of personal income grows. Poll taxes (aka head taxes), levied as a fixed amount per capita, patently are regressive.

It is not simple to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of the uncertainty around the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden is dependant fundamentally on whether a national or a subnational (that is, provincial or state) tax is being decided.

In regarding the economic purpose of taxation, it is essential to distinguish between differing concepts of tax rates. The statutory rates are nominated in the law; often these are marginal rates, but occasionally they are average rates. Marginal income tax rates signify the fraction of incremental income demanded by taxation when income rises by one dollar. So, if tax onus increases by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax laws usually contain graduated marginal rates—i.e., rates that grow as income rises. Structured analysis of marginal tax rates need to consider provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) decreases by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points greater than specified within the statutory rates. Since marginal rates indicate how after-tax income moves in response to changes in before-tax income, they are the appropriate ones for appraising incentive effects of taxation. It is even more difficult to nominate the marginal effective tax rate applied to income from business and capital, as it may be dependant on such factors 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 nothing under a consumption-based tax.

Average income tax rates signify the portion of total income that is required in taxation. The pattern of average rates is the one that is relevant for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates usually grow with income, both because personal allowances are granted for the taxpayer and dependents and due to that marginal tax rates are graduated; conversely, preferential treatment of income received predominantly by high-income households might dampen these effects, allowing regressivity, as displayed by average tax rates that fall as income rises.

The Development of Data Projectors

The LCDs built in projection systems are typically small reflective or transmissive panels illuminated by a forceful arc lamp source. A series of lenses expands the reflected or transmitted image and then sends it on a screen. In front-projection systems the LCD is placed on the same area of the screen as the viewer, while in rear-projection systems the screen is set off from behind. Projectors of greater expense and performance may be found with three separate LCD panels, casting separate red, green, and blue images that mesh to create a coloured image on the screen.

The growing requirement for visual presentations has had a growth in emphasis on the switching speed of liquid crystals. This has led to the creation of items employing smectic liquid crystals, certain kinds of which emit a speedier electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most progressive smectic device. In it the liquid crystal molecules are managed in perpendicular layers to the substrate planes, which are differentiated by one or two micrometres, and in the layers the molecules are tilted, as displayed in the figure. The host liquid crystal possesses optically active molecules, and a minor outcome of the optical activity and the tilt of the molecules is the presence 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 throughout the plane of the layers. Therefore, there is a permanent charge separation across the liquid crystal layer in the SSFLC, and its sign is directly attracted 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 so reverse the tilt direction of the molecules. The corresponding change in optical properties can effect a change from light to dark in the case that one or more polarizers are used.

SSFLC devices have been commercialized for big passive-matrix displays, but their cost and complexity has impeded them from creating any remarkable effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some probability for use as parts in projection systems or as viewfinders in digital cameras. Their immediate reaction allows them to be used in time-sequential colour systems, in which highly expensive colour filters are replaced by a coloured backlight that flashes red, green, and blue in rapid succession (about 100 cycles every second). For example, the liquid crystal may be switched to a transmissive state for the red and green periods but then to a nontransmissive state in the blue period, with the end result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Of all furniture needs, the chair might be primary. While many other objects (save for the bed) are intended to support objects, the chair supports the human form. The term chair must be regarded here in the largest sense, from stool to throne to further makes such as the bench and sofa, which can be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously defined.

The social history of the chair is as intriguing as its history as a creative craft. The chair is not just a physical support or an aesthetic piece; it can also be semiotic of social place. In the old royal courts there were plain signifiers between sitting on a chair with arms, or a chair with a back but no arms, or having to sit on a stool. In the 20th century, a director’s and/or manager’s chair has been iconic of superior status, and even in democratic government meeting the speaker sits on a raised platform.

In its furniture form, the chair can be used for a number of variations. There are chairs designed to attend to man’s age and physical condition (the high chair, the wheelchair) and to indicate his position in society (the executive chair, the throne). In past days there were chairs used for birthing (birth chairs); from the 20th century, there have been chairs for ending life (the electric chair). There are chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We can have chairs that can be folded, chairs on wheels, and chairs on runners.

Contemporary lifestyle has designated unique chairs for use in automobiles and aircraft. Each of these chair shapes have been perfected to fit to different human requirements. Because of its significant connection with man, the chair exists to its full advantage only when in employ. Although it does not make any difference to one’s appreciation of a cupboard or a set of drawers whether there might be anything inside or not, a chair is understood and regarded best with a person using it, for chair and sitter need one another. Thus the individual limbs of a chair are labeled likened to the names of the human body: arms, legs, feet, back, and seat.

Because the principal purpose of your chair is to support your body, its value is tested principally for how fully it does measure up to this practical role. In the structure of a chair, the maker is bound by particular static law and principal measurements. Inside these restrictions, however, the chair designer has awesome freedom.

The history of the chair was a period of several thousand years. There existed peoples that held unique chair types, as seen of the highest work in the spheres of handling and creativity. From these peoples, particular 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 lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the structures of careful design, are now found from findings made in tombs. The first one of these two is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair would have four legs crafted not unlike those of a chosen animal, a curved seat, and leading to a sloping back supported with vertical stretchers. From this design a strong triangular structure was obtained. There was apparently no notable differentiation from the construction of Egyptian thrones and chairs for typical people. The general variation was in the brand of ornamentation, in the particulars of more valuable inlays. The Egyptian folding stool most probably was manufactured to be an easily stored seat for army officers. As a camp stool the chair persevered til much later days. But the stool then was designed as the character of a ceremonial seat, its mechanical function as a folding stool being forgotten. This can from today’s evidence be noted, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were constructed in the shape of folding stools but cannot be folded because the seats were formed with wood. The plain structure of the folding stool, made of two frames that spin on metal bolts and support a seat of leather or fabric secured between them, was then seen some time later in the Bronze Age folding chairs of Scandinavia and northern Germany. The better recognised of those is the folding stool, made from ashwood, seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is found not as any ancient item still around but from a trove of pictorial objects. The better recognised is the klismos posited on the Hegeso Stele at the Dipylon burial place by Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, only two of them could be seen. These curving legs were probably executed out of bent wood and were thus bore extreme pressure under the weight of the sitter. The joints fastening the legs to the frame of the seat had to be therefore extremely solid and were visibly indicated.

The Romans embued the Greek chair; some models of seated Romans offer examples of a denser and in appearance rather less intricately built klismos. Both features, the light and the heavy, were popularised as part of the Classicist epoch. The klismos influence can be seen in French Empire styles, in English Regency, and in special forms of notable uniqueness around Denmark and Sweden from 1800.

China
The past of the chair in China cannot be tracked as far as in Egypt and Greece. Since the Tang dynasty (AD 618–907) a full folio of images and paintings has been kept safe, showing the inside and exteriors of Chinese homes and the furniture. Another preservation of the 16th century are some chairs crafted of wood or lacquered wood, that bear an interesting likeness to pictures of previous chairs.

Just like in Egypt, there existed two particular chair designs in China: a chair of four legs and a folding stool. This four-legged chair was found both with and without arms but never missing its square seat and straight stiles (vertical side supports) to give support to the back. In one design, it must be said, the stiles could be delicately curved above the arms to conform correctly to the form of the S-shaped back splat (the central upright of its chairback). Each of the three parts are mortised on the yoke-like top rail. Though the idea of a back splat exercised a foundation for English chairs in the Queen Anne period, wooden items that only just to a limited limit stabilise corner joints (as well as being loose in the result) represent a signature signatory to Chinese chairs. The four legs pass through the seat frame, which finishes upon the rounded staves. All the members are round in section or have rounded edges—references perhaps to the bamboo tradition. The seat is not comfortable and may have a plaited bottom. These chairs demanded of the sitter to stay stiff and upright; if too much weight is placed on the back, the chair has a tendency to topple. In patriarchal Chinese households of this epoch armchairs likely were allowed only for elderly individuals, for they were given great esteem.

The Chinese folding stool is thought to have travelled to China from the West. It does not vary so very much from the Egyptian or Scandinavian folding stools, but it has a variation in that the top rail is delicately fixed to the two legs of the stool with a curved member, which is often provided with metal mounts. From a Western understanding the resulting effect of both these furniture designs is stylized. The constructive and decoration issues are combined in a manner that is all at once both naïve and refined. The piecemeal appearance is an upshot of the fact that the individual parts do not look to have been fixed by use of either glue or screws, but had been mortised with one another and locked into position in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also left its signature on the chair. Works of art display a style of chair with a relatively unrefined wooden frame; a back and seat, nailed on, consisting of two layers of leather, with horsehair stuffing in between the layers, stitched to show up a pattern of small pads. The front board and a similar board at the back could be folded after unscrewing some small iron hooks. In this way the chair was a readily portable piece of furniture for traveling which, in the same era, gave the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is evidenced in engravings of the inside of wealthy Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this design of chair may also be found in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not believed that the style actually started in The Netherlands. Typically, the legs of the chair were smooth, round in section, and of thin measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was produced in impressive quantities, as evidenced from one of Abraham Bosse’s engravings, in which there is a row of those chairs lined up against a wall. The form asserts itself by virtue of its shapely proportions and fine upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of styles—that was, as brought out in Paris around 1750—spread through most of Europe and has been imitated or copied in the mid-20th century. The chair owes the popularity to a combination of comfort and charm. The seat suits to the human body and grants a relaxed seated position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are little upholstered pads covering the armrests. Smooth transitions achieved between seat frame, legs, and back cover all the joints, which are stable, constructed on craftsmanlike practices despite the absence of stretchers between the legs.

French Rococo chairs and imitations thereof have wood of fairly thick dimensions; but every member is deeply molded, all extraneous wood has been cut away, and more upmarket chairs may be further embellished with highly delicate and decorative carvings. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry is used for any upholstery on the seat, back, and armrests; crosshatched cane is in some cases used instead of upholstery.

English chairs from the 18th century were more differentiated in design than the French. The French touch for stylistic uniformity, which lead from the highest circles in Paris and Versailles within most of France and was popular 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 well-known 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 versions 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, purport that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recording of the money values of the operation of a business. Bookkeeping provides the numbers from which accounts are prepared but is a distinct process, prerequisite to accounting.

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

Management officials, investors, and credit grantors all require this information: management so as to understand the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to understand the results of business operations and make decisions for buying, holding, and selling securities; and credit grantors in order to regard the financial statements of a business in assessing whether to give a loan.

Traces of financial and numerical records can be found for nearly every country with a commercial backbone. Records of trade contracts were discovered in the archaelogy of Babylon, and accounts for both farms and estates had been kept in ancient Greece and Rome. The double-entry method of bookkeeping started with the furthering of the commercial republics of Italy, and tutorials for bookkeeping were created within the 15th century in many Italian cities.

During the late 18th and early 19th centuries, the Industrial Revolution gave an important stimulus to accounting and bookkeeping.

The development of manufacturing, trading, shipping, and subsidiary services made accurate financial books a requirement. The past of bookkeeping, in fact, resembles closely the past of commerce, industry, and government and, in part, helped forming it. The worldwide movement of industrial and commercial activity required higher professional decision-making methodology, which in turn demanded more sophistication in the selection, classification, and presentation of information, more so with the progression of computers. Taxation and government regulation became more detailed and resulted in greater need for information; business entities had to provide information to support their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew in size, and the demand for bookkeeping for their own inner operations increased.

Though bookkeeping processes can be very multifaceted, all of it is based on two types of books utilised in the bookkeeping procedure—journals and ledgers. A journal must have the daily transactions (sales, purchases, and so on), and the ledger should have the records of individual accounts. The daily records from the journals are entered in the ledgers.

Every month, as a general rule, an income statement and a balance sheet are constructed from the trial balance posted from the ledger. The duty of the income statement or profit-and-loss statement is to present an analysis of the changes that took place in the ownership equity because of the events of the period. The balance sheet gives the financial condition of the enterprise at any particular point regarding 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 produced 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.
