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

The most typical question asked when looking for a new projector for the home, office, or classroom is: will I get an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, short for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many company brands and different types available, it can be overwhelming for customers to choose between these technologies. Ultimately LCD projectors offer superior image quality and colour accuracy. The article below explains why DLP projectors struggle with creating a comparable standard of image quality.

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

How the light source is processed from the point at which the projector switches on to when the picture reaches your screen is vitally significant to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by dividing it into red, blue and green components, by three mirrors which direct the coloured light to 3 different LCD panels. The 3 LCD panels create the elements of the image by processing each pixel on and off. The pixels are then projected in a glass prism to form the projector image. An important point to realise about LCD projectors is that all three colours are sent onto your projected surface all at once. The way a DLP projector operates is vastly different and even 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 approach to forming an image forms a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to create the image elements. The elements of the image are projected 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 whole image. From LCD projectors, all colours are available all the time to deliver the highest brightness and fantastic colour accuracy. In DLP, only one colour is available at a time, resulting in lower colour brightness and accuracy. Some DLP developers have added a white segment into the colour wheel to improve all over brightness, but this also lessens colour accuracy.

I read in forums all the time that DLP gives a higher contrast ratio and ergo must be superior quality. For those who do not know, 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 offer high contrast specifications compared to a majority of LCD projectors. At one glance, this appears to be a plus, however, in the real world, the true black level is determined by the ambient light in the room while the projector is in use. Do not be fooled by contrast specifications on websites and in brochures.

When the content you wish to view includes moving images, DLP projection technology also has image errors, or ‘artifacts’. The most common artifact that a DLP projector displays with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change between the time red, blue and green colours are pulled up. LCD projectors do not have this disadvantage because every colour is processed at once. DLP builders have developed 3DLP solutions using 3 chips to solve the colour break up artifacts, but the price of these projectors make them almost impossible for most businesses and consumers.

Another difference between LCD and DLP is how they make up for the refractive qualities of light. Take yourself back to high school science, and remember when they taught you how the various colours of light refract differing amounts when passing through the same lens. The disadvantage with DLP projectors is that they take the one same panel for the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light in a different way. Generally with a DLP projector, some extra yellow colour will come up above and an extra blue will be projected below an image of something as simple as a lone black line. In manufacturing LCD projectors can be adjusted to minimize these effects on the projected image, as each colour is processed on separate LCD panels.

The one real benefit (excluding price) with deciding on a DLP projector is its smaller size and weight. However, this is only relevant to portability and must be traded off against the image superiority of LCD projectors. If resulting picture quality is important to you, then the answer is easy. Go for an LCD projector! LCD projectors will constantly produce bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch found dominance in sea power during the 17th century, the initial yacht became a leisure craft used initially by royalty and secondly by the burghers for the canals and then in the protected and unprotected waters of the Low Countries. Racing yachts was incidental, borne from private matches. English yachting started with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English throne 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, sovereign 1685–88), ordered for other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 bet. Yachting became classy with the affluent and nobility, but after that point the habit did not last.

The first yacht group in the British Isles, the Water Club, was started around about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and held great naval panoply and gravity. The closest thing to a race was the “chase,” in which the “fleet” pursued an imagined enemy. The club persisted, largely as a social club, until 1765, and in 1828, by merging with other societies, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some stipulated manner on the Thames about the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV came to sovereignty in 1820, it was called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been initiated 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 racing. The organisation at Cowes became the Royal Yachting Club, likewise at the ascension of George IV. Every member was required to own boats of at least 20 tons (20,321 kg). Sailing races for large bets were held, and the club life was wonderful. Eventually Royal Yachting Club boats increased 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 persisted when the English took dominance. Sailing was largely for pleasure and found its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and established a benchmark of luxury and elegance for the later yachts in that area from the late 19th century. The first continuing American yacht group, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts took the design of such naval craft as brigantines, schooners, and cutters from the 17th century through to the later half of the 19th century. The style of bigger yachts was originally heavily put upon by the victory of America, which was created by George Steers for a association headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its success at Cowes in 1851. The first yachts were not designed and built in the modern sense, with only a model being used. Not until the second half of the 19th century did what was labeled naval architecture come into action. Not until the 1920s did the application of the science of aerodynamics do for the design of sails and rigging what it had previously done for hulls.

Because nearly all sailboats had been individually manufactured, there was a requirement for handicapping boats previous to the one-design class boats were made. Therefore, a rating rule came into being, which is found in the International Rule, taken on in 1906 and edited 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 manufactured to standard dimensions in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between such boats can be done on an even playing field with no handicapping at all. A perfect example is the generic International America’s Cup Class taken on board for racers in the 1992 America’s Cup race.

As long as yachting belonged mostly for the aristocracy and the wealthy, money was no object, and the size of boats increased, in both length and weight. The ascendancy and popularity of smaller craft happened in the second half of the 19th century from the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A journey around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the seaworthiness of less sizeable yachts. Later in the 20th century, particularly after World War II, smaller racing and pleasure boats became more common, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, when steam was set to replace sail power in public vessels, the steam engine, and later the internal-combustion engine, were used increasingly in personal yachts. Bigger power yachts were progressed to a high element, and long-distance sailing turned into a favourite pastime of the wealthy. The first power yachts were paddle-wheel boats; these then gave rise to those powered by the fully submerged screw or propeller sort of propulsion. As in the case of naval and merchant vessels, auxiliaries possessing both sail and power were the yacht fashion for several years. By the latter half of the 20th century, a lot of yachts were still auxiliaries, but the larger part were exclusively power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a push in the design of bigger steam yachts. In particular within these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was operated by a crew of at least 150. The Mayflower, bought by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and saw active service during 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, with heavy oil for fuel, advanced during World War I. In the decade that followed, bigger power-yacht building grew, reaching a climax in the Orion (1930) at 3,097 tons. From that point the biggest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of bigger power craft declined after 1932, and the fashion thereafter was for smaller, less costly craft. Following World War II, many small naval boats were traded by private owners for conversion to yachts. At the late 20th century, yachting is a widespread popular sport enjoyed by thousands of yachtsmen who are actually sailing and keeping their own small pleasure yachts. The popularity of boats and owners has increased steadily, not only in the traditional areas on the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be categorized by the effect they have on the distribution of income and wealth. A proportional tax is a kind that places the same relative burden on each taxpayer—i.e., in the case where tax liability and income move in relative scale. A progressive tax is characterized by a higher than proportional increase in the tax liability in relation to the growth in income, and a regressive tax is characterized by a less than proportional rise in the relative onus. Thus, progressive taxes are viewed as taking away inequity in income distribution, while regressive taxes may have the effect of increasing these inequalities.

The taxes that are often believed to be progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, can become less so within the upper-income categories—in particular if a taxpayer is able to reduce his tax base by declaring deductions or by taking some certain income aspects from his taxable income. Proportional tax rates if applied to lower-income categories can also be more progressive if such personal exemptions are declared.

Income measured over the period of a year may not definitely provide the most suitable measure of taxpaying ability. For example, transitory growth in income may be saved, and within temporary declines in income a taxpayer may opt to pay for consumption by taking from savings. So, if taxation is held in comparison along with “permanent income,” it can be less regressive (or more progressive) than when it is compared with annual income.

Sales taxes and excises (save luxuries) tend to be regressive, because the portion of individual income consumed or spent on specific goods decreases as the level of personal income grows. Poll taxes (aka head taxes), calculated as a set amount per capita, clearly are regressive.

It is complicated to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of uncertainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of determining who bears the tax burden rests fundamentally on whether a national or a subnational (that is, provincial or state) tax is being debated.

In assessing the economic effects of taxation, it is important to distinguish between various ideas of tax rates. The statutory rates will be nominated in the legislation; usually these are marginal rates, but in some cases they are median rates. Marginal income tax rates note the fraction of incremental income taken by taxation when income is increased by one dollar. Therefore, if tax burden rises by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax legislature generally contain graduated marginal rates—i.e., rates that grow as income increases. Structured analysis of marginal tax rates should consider provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) reduces by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points more than indicated in the statutory rates. Since marginal rates indicate how after-tax income increases or decreases in response to changes in before-tax income, they are the necessary ones for appraising incentive effects of taxation. It is even more difficult to realise the marginal effective tax rate applicable to income from business and capital, since it may be reliant on factors including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates show the fraction of total income that is taken in taxation. The pattern of average rates is the one that is important for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates generally grow with income, both because personal allowances are allowed for the taxpayer and dependents and due to that marginal tax rates are graduated; conversely, preferential treatment of income received for the most part by high-income households might dampen these effects, forcing regressivity, as shown by average tax rates that lessen as income rises.

The Development of Data Projectors

The LCDs utilised in projection systems are usually small reflective or transmissive panels illuminated by a powerful arc lamp source. A series of lenses enlarges the reflected or transmitted image and then casts it on the screen. For front-projection systems the LCD is placed on the side of the screen as the viewer, however in rear-projection systems the screen is set off from behind. Projectors of more expense and capacity may have three distinct LCD panels, forming separate red, green, and blue images that mesh to reflect a coloured image on the screen.

The increase in need for film displays has placed a special emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of objects using smectic liquid crystals, certain types of which have a faster 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. With it the liquid crystal molecules are cast in layers that are perpendicular to the substrate planes, which are distanced by one or two micrometres, and inside the layers the molecules are slanted, as demonstrated in the figure. The host liquid crystal holds optically active molecules, and a slight consequence of the optical activity and the shape of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, similar 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. Hence, there must be a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly paired to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and by doing so reverse the tilt direction of the molecules. The corresponding change in optical properties can make a change from light to dark when one or more polarizers are utilised.

SSFLC devices have been produced for big passive-matrix presentations, but their expense and complex nature has hindered them from making any significant impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some possibility for use as aspects in projection systems or as viewfinders in digital cameras. Their quick response allows them to be made use of in time-sequential colour systems, in which expensive colour filters are replaced with a coloured backlight that flashes red, green, and blue in quick pace (around 100 cycles per second). For example, the liquid crystal can be switched to a transmissive state during the red and green periods and then to a nontransmissive state in the blue period, creating 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 forms, the chair may be the most imperative. While many other objects (save for the bed) are created to support objects, the chair supports a human form. The term chair is intended to be regarded here in the widest sense, from stool to throne to derivative items including the bench and sofa, which should be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not overtly definitive.

The social history of the chair is as interesting as its history as an art and craft. The chair is not merely a physical support and/or an aesthetic artwork; it historically is a symbol of social place. In the past royal courts there were significant connotations between possessing a chair with arms, sitting on a chair with a back but without arms, and having to use a stool. From the 20th century, a director’s or manager’s chair has been regarded as a signifier of superior standing, and even in democratic governments the speaker sits on a high-set platform.

In a furniture purpose, the chair holds a range of various makes. There are chairs created to fit man’s age and physical form (the high chair, the wheelchair) and to indicate his standing in society (the executive chair, the throne). Since past days there were chairs for birthing (birth chairs); during the 20th century, there have been chairs used to die in (the electric chair). There are chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We make chairs that can be folded, chairs on wheels, and chairs on runners.

Our modern lifestyle has derived particular chairs for use in automobiles and aircraft. All of these chair kinds has been evolved to suit to changing human needs. Because of its particular importance with man, the chair comes to its full advantage only when in employ. Though it doesn’t make a difference to one’s appreciation of a cupboard or a bureau if there is anything inside or not, a chair is understood and tested by a person utilising it, for chair and sitter complement each other. Thus the several areas of a chair were given labels likened to the limbs of a human shape: arms, legs, feet, back, and seat.

Because the primary purpose of your chair is to support our human body, its worth is valued principally on how fully it does measure up to this practical purpose. Within the construction of the chair, the chair maker is restricted for the static legislation and principal measurements. Under these rules, however, the chair designer has extensive freedom.

The history of the chair covers an epoch of several thousand years. There are societies that held distinctive chair types, expressions of the principal work in the industries of craft and aesthetics. Out of these such civilisations, special mention should 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 items of careful craft, were found from findings made in tombs. One of these is a four-legged chair with a back, the other a folding stool. The original Egyptian chair had four legs designed like those of a chosen animal, a curved seat, with a sloping back supported above vertical stretchers. From this a solid triangular form was crafted. There was in our understanding no notable differentiation in the structure of Egyptian thrones and chairs for ordinary populace. The general difference was in the level of ornamentation, in the choice of pricey inlays. The Egyptian folding stool in all probability was developed as an easily stored seat for army soldiers. As a camp stool that kind stayed around for much later points in time. But the stool then also was designed as the use of a ceremonial seat, its technical history as a folding stool neglected or forgotten. This can from today be seen, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were constructed in the structure of folding stools but aren’t able to be folded because the seats were created of wood. The plain manufacture of the folding stool, consisting of two frames that cycle on metal bolts and hold a seat of leather or fabric set between them, then appeared but somewhat later during the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognised of this kind is the folding stool, made of ashwood, which can now be found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is found not from any ancient specimen still in form but from a large amount of pictorial items. The archetype is the klismos depicted on the Hegeso Stele at the Dipylon burial ground in outer Athens (c. 410 BC). It is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of them were shown. These unusual legs were probably manufactured of bent wood and were thus needed to bear huge pressure under the weight of the sitter. The joints attaching the legs to the frame of the seat had to be therefore very durable and were visibly pointed out.

The Romans borrowed from the Greek chair; a number of models of seated Romans are evidence of a denser and apparently rather less intricately designed klismos. Both features, the light or heavy, were popularised as part of the Classicist period. The klismos influence is found in French Empire design, in English Regency, and in some special forms of notable originality within Denmark and Sweden around 1800.

China
The progression of the chair in China isn’t able to be traced as long as the ancestry of the chair in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an undamaged folio of sketches and paintings was kept safe, showing the insides and outer parts of Chinese homes and the designs of furniture. Also preserved from the 16th century are a number of chairs of wood or lacquered wood, that possess an astonishing similarity to styles of ancient chairs.

As was the case in Egypt, two particular chair forms existed in China: a chair that had four legs and a folding stool. The four-legged chair can be constructed both with and without arms however never without its square seat and straight stiles (standing side supports) to firm the back. In one design, though, the stiles had been marginally curved above the arms so as to conform correctly to the form of the S-shaped back splat (the centre upright of a back). All three limbs were mortised in the yoke-like top rail. Though the innovation of the back splat then had an influence on English chairs within the Queen Anne period, wooden pieces that only just to a limited ability stabilise corner joints (and were loose in the result) indicate a feature signatory to Chinese chairs. The four legs sit through the seat frame, which closes over the rounded staves. Members are round in section or has rounded edges—an acknowledgement as may be to the bamboo tradition. The seat is not comfortable and may have had a plaited texture. These chairs required of the sitter to hold themselves stiff and upright; when too much weight is forced on the back, the chair has a tendency to fall. In patriarchal Chinese houses of this epoch armchairs probably were reserved only for senior family members, for they were given great esteem.

The Chinese folding stool is thought to have travelled to China from the West. It does not differ very much from the Egyptian or Scandinavian folding stools, but it possesses 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 usually provided with metal mounts. From a Western viewpoint the ultimate effect of both furniture forms is stylized. The constructive and decorative aspects are combined in a style that is at the same time naïve and refined. The patchwork appearance is an upshot of the fact that the individual members do not look to have been constructed with either glue or screws, but have 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 put its signature on the chair. Artworks project a style of chair with a relatively brusque wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in the layers, stitched to bring out a pattern of small pads. The front board and a related board from the back could be folded after unscrewing some tiny iron hooks. In this way the chair was an easily portable piece of furniture while traveling which, in the same era, had the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair can be displayed in engravings of interiors of affluent Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this type of chair can also be found in countries where Dutch styles of interior decoration and Dutch furniture won favour, it is not certain that the form actually was born in The Netherlands. Usually, the legs of the chair were smooth, round in section, and of slim measurements; they are occasionally baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was produced in large quantities, as surmisable from one of Abraham Bosse’s engravings, in which there is an entire row of those chairs lined up against a wall. The style 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 forms—that is to say, as developed in Paris around 1750—conquered most of Europe and has been imitated or copied during the mid-20th century. The model owes the popularity to a combination of relaxation and charm. The seat suits to the human body and allows a relaxed sitting position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are tiny upholstered pads covering the armrests. Smooth transitions achieved between seat frame, legs, and back conceal all the joints, which are stable, constructed on craftsmanlike methods despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them are constructed from wood of quite thick dimensions; but all members are deeply molded, all extraneous wood has been taken away, and finer designs might be further embellished with special delicate and decorative carvings. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for all of the upholstery on the seat, back, and armrests; crosshatched cane is occasionally used as an alternative to upholstery.

English chairs from the 18th century were more variable in form than the French. The French touch for stylistic uniformity, which lead from the royal circles in Paris and Versailles within most of France and became the preference in many 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 popularised and was widely distributed throughout the world.

Late 18th to 20th century
In 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, suggest 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 grants the numbers from which accounts are written but is a previous process, required prior to accounting.

Basically, bookkeeping records two kinds of information: (1) the current value, or equity, of the business and (2) the change in value—profit or loss—taking placement in the enterprise within a given time period.

Management officials, investors, and credit grantors all demand such information: management in order to interpret the upshots of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to understand the outcome of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors in order to judge the financial statements of an enterprise in judging whether to grant a loan.

Bits and pieces of financial and numerical record charts can be seen for just about every group of people with a commercial backbone. Records of business contracts have been uncovered in the archaelogy of Babylon, and accounts for both farms and estates were archived in ancient Greece and Rome. The two-entry way of bookkeeping came up with the development of the business republics of Italy, and tutorial manuals for bookkeeping were created during the 15th century in many Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made correct financial books a necessity. The ancestry of bookkeeping, in fact, resembles the history of commerce, industry, and government and, partially, assisted to form it. The international spread of industrial and commercial activity demanded greater sophisticate decision-making processes, which in turn required more sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government legislation became more important and resulted in even greater need for information; enterprising firms had to show 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 need for bookkeeping for their inner operations became higher.

Although bookkeeping methodology can be rather multifaceted, all of it is based on two types of books used in the bookkeeping procedure—journals and ledgers. A journal contains the daily transactions (sales, purchases, and so forth), and the ledger has the details of individual accounts. The daily records from the journals are written in the ledgers.

Every month, generally, an income statement and a balance sheet are prepared from the trial balance posted in the ledger. The purpose of the income statement or profit-and-loss statement is to show an analysis of the changes that took place in the entity equity due to the transactions of the period. The balance sheet displays the financial condition of the corporation at a particular date derived from 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.
