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

The most typical question that is asked when acquiring a new projector for the home, office, or classroom is: would I get an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many different brands and models available, it can be difficult for the buyer to pick between both technologies. The simple fact of the matter is that LCD projectors give superior image quality and colour accuracy. The article below explains why DLP projectors struggle with reproducing an equal grade of image quality.

Visualise a set of blinds in your house covering your bedroom window. By pulling on a rod you can turn the shutters open or closed, according to if you want to let light in or not. And such is exactly how an LCD projector behaves. Each pixel operates like a single shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is formed 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 switches on to when the content reaches your screen is extremely significant in regard to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by dividing it into red, blue and green components, by three mirrors which project the coloured light to 3 different LCD panels. The 3 LCD panels form the elements of the image by processing each pixel on and off. The pixels are then projected in a glass prism to create the projector image. A point to realise about LCD projectors is that all three colours are delivered onto your projected surface at once. The way a DLP projector runs is vastly different and even the produced image appears is not the same. With DLP, white light from the lamp is sent through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of creating an image requires a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to create the image elements. The elements of the image are sent in sequence on the screen, one colour at a time. The viewer’s eyes will then put together each coloured element of the image into a single complete image. From LCD projectors, all colours are available all the time to form the highest brightness and great colour accuracy. In DLP, just one colour is available at a time, causing lower colour brightness and accuracy. Some designers have included a white segment for the colour wheel to improve brightness overall, but this also lessens colour accuracy.

I hear in forums all the time that DLP provides a higher contrast ratio and therefore must be better quality. 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 system is capable of producing. DLP projectors do have high contrast specifications as compared to a majority of LCD projectors. At a glance, this can seem to be a benefit, however, in truth, the true black level is determined by the ambient light in the room where the projector is being used. Do not be fooled by contrast specifications on websites and in brochures.

When the content you are trying to view needs moving images, DLP projection technology can also create image errors, or ‘artifacts’. The most typical artifact that a DLP projector shows with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change position between the time red, blue and green colours are displayed. LCD projectors do not have this characteristic because all the colours are projected at the same time. DLP designers have created 3DLP solutions using 3 chips to resolve the colour break up artifacts, but the cost of these projectors make them impractical for the large part of businesses and consumers.

Another differentiation between LCD and DLP is how they balance for the refractive qualities of light. Jump back to high school science, and recall how the various colours of light refract various amounts when shone through the same lens. The downfall with DLP projectors is that they utilise the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light at different levels. Usually with a DLP projector, some yellow colour will appear above and an extra blue will be projected below an image of something as simple as a lone black line. During manufacturing LCD projectors can be adjusted to take away these effects on the projected image, as each colour is projected on a separate LCD panels.

The sole real plus (excluding price) with choosing a DLP projector is its smaller overall size and weight. However, this is only relevant for portability and must be traded off against the image advantages of LCD projectors. If overall picture quality is important to you, then the answer is no-brainer. Choose an LCD projector! LCD projectors will always create bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch came to preeminence in sea power during the 17th century, the early yacht had been a leisure craft used first by royalty and secondly by the burghers on the canals and the protected and unprotected waters of the Low Countries. Yacht racing was incidental, arising as private games. 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 gave him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, sovereign 1685–88), built additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 punt. Yachting became popular among the wealthy and royalty, but after that time 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 had great naval panoply and gravity. The closest thing to a race was the “chase,” when the “fleet” pursued an imagined enemy. The club endured, largely as a social club, until 1765, and in 1828, after conglomerating with other clubs, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some ordered method 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 came to be named 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 association had been initiated at Cowes on the Isle of Wight in 1815, and royal patronage made the Solent – the strait between the mainland and the Isle of Wight – the perpetual setting of British racing. The society at Cowes became the Royal Yachting Club, again at the ascension of George IV. All members were required to own boats of at least 20 tons (20,321 kg). Sailing tests for large bets were held, and the social life was wonderful. Ultimately Royal Yachting Club boats grew in size to over 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and persisted when the English held control. Sailing was largely 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 sophistication for the later yachts in the area from the late 19th century. The first continuing American yacht society, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens began the New York Yacht Club aboard 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 later half of the 19th century. The craft of large yachts was initially largely affected by the victory of America, which was drawn by George Steers for a club started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its success at Cowes in 1851. Earlier yachts were not designed and built in today’s sense, with only a model used. Not until the latter half of the 19th century did what was labeled naval architecture come into action. Not until the 1920s did the employment of the research of aerodynamics do for the design of sails and rigging what science had already done for hulls.

Because almost all sailboats had to be individually manufactured, there came a desire for handicapping boats previous to the one-design class boats were built. Hence, a rating rule came into being, which resulted in the International Rule, adopted in 1906 and edited in 1919. Today, one of the fastest flourishing areas in the field of sailing is that of one-design class boats. All boats in a one-design class are created to standard requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing these boats can be had on an even par with no handicapping necessary. A great example is the standard International America’s Cup Class taken on board for racers in the 1992 America’s Cup race.

For the time that yachting was an activity mostly for the aristocracy and the wealthy, cost was no issue, and the size of boats increased, in both length and weight. The rise and preference of smaller yachts came in the later 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 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 boats. Later in the 20th century, notably after World War II, smaller racing and recreational craft became more popular, down to the dinghy, a favourite 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
Following the decade 1840–50, in which steam was set to emulate sail power in commercial vessels, the steam engine, and later the internal-combustion engine, were favoured increasingly in personal craft. Bigger power yachts were progressed to a high degree, and long-distance cruising turned into a favoured activity of the wealthy. The early power yachts were paddle-wheel boats; those then gave rise to boats powered by the fully submerged screw or propeller type of propulsion. As in the case of naval and merchant vessels, auxiliaries possessing both sail and power were the yacht fashion for many years. By the later half of the 20th century, a lot of yachts were still auxiliaries, but the large part were solely power yachts with gasoline or diesel engines.

In the last decade of the 19th century there was a rise in the design of large steam yachts. In particular among 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 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 gave active service during World War II.

As bigger and better quality internal-combustion engines were developed, many bigger boats were using them for power. The creation of the diesel engine, employing heavy oil for fuel, advanced from World War I. During the decade after, big power-yacht building blossomed, hitting a climax in the Orion (1930) at 3,097 tons. During that point the largest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of big power yachts lessened in 1932, and the trend after that was toward smaller, less expensive craft. From World War II, a lot of small naval boats were bought by private owners for conversion to yachts. In the late 20th century, yachting had become a widespread loved activity enjoyed by thousands of yachtsmen who are actually sailing and upkeeping their own small pleasure boats. The number of boats and owners has increased steadily, not only in the traditional places on the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are distinguished by the effect they have on the allocation of income and wealth. A proportional tax is a tax that imposes the same relative burden on every taxpayer—i.e., when tax liability and income move in equal proportion. A progressive tax is characterized by a higher 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 rise in the comparable onus. Therefore, progressive taxes are thought of as fighting a lack of equality in income distribution, while regressive taxes can result in an increase these inequalities.

The taxes that are often thought to be progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, can become less so in the upper-income group—especially if a taxpayer is able to reduce his tax base by declaring deductions or by excluding some income elements from his taxable income. Proportional tax rates if applied to lower-income groups can also be more progressive if such personal exemptions are made.

Income measured over the course of a given year might not absolutely give the most accurate measure of taxpaying requirements. For example, transitory increases in income may be saved, and during temporary declines in income a taxpayer could elect to pay for consumption by decreasing savings. So, if taxation is regarded alongside “permanent income,” it can be less regressive (or more progressive) than when made comparable with annual income.

Sales taxes and excises (with the exception of luxuries) are usually regressive, because the portion of one’s income consumed or spent on specific goods decreases as the amount of personal income is raised. Poll taxes (also known as head taxes), levied 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, due to the uncertainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden depends fundamentally on whether a national or a subnational (that is, provincial or state) tax is being debated.

In assessing the economic purpose of taxation, it is important to distinguish between various points of tax rates. The statutory rates are nominated in law; usually these are marginal rates, but occasionally they are mean rates. Marginal income tax rates signify the fraction of incremental income demanded by taxation when income grows by one dollar. Thus, if tax burden increases by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax legislation often contain graduated marginal rates—i.e., rates that increase as income rises. Structured analysis of marginal tax rates are required to review provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lessens by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than nominated by the statutory rates. Since marginal rates signify how after-tax income changes 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 applied to income from business and capital, as it may be reliant 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 indicate the portion of total income that is paid in taxation. The pattern of average rates is the one that is important for considering the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates usually increase with income, both because personal allowances are provided for the taxpayer and dependents and also because marginal tax rates are graduated; on the other side of things, preferential treatment of income received fundamentally by high-income households may dampen these effects, producing regressivity, as shown by average tax rates that lessen as income increases.

The Development of Data Projectors

The LCDs built for projection systems are most often small reflective or transmissive panels set off by a powerful arc lamp source. A series of lenses magnifies the reflected or transmitted image then casts it onto a screen. In front-projection systems the LCD is placed on the same area of the screen as the viewer, although in rear-projection systems the screen is set off from behind. Projectors of higher cost and capacity may use three separate LCD panels, casting separate red, green, and blue images that combine to form a coloured image on the screen.

The increasing need for video presentations has had a growth in emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of items employing smectic liquid crystals, some types of which emit a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most complex smectic device. Within it the liquid crystal molecules are arranged in layers perpendicular to the substrate planes, which are distanced by one or two micrometres, and throughout the layers the molecules are tilted, as displayed in the figure. The host liquid crystal holds optically active molecules, and a minor result of the optical activity and the slant of the molecules is the appearance 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 throughout the plane of the layers. Therefore, there is a permanent charge separation over 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 right sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The respective change in optical properties can make a change from light to dark if one or more polarizers are employed.

SSFLC devices have been marketed for big passive-matrix presentations, but their expense and complexity has stopped them from having any great effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some promise for use as parts in projection systems or as viewfinders in digital cameras. Their speedy responding allows them to be employed in time-sequential colour systems, in which dear colour filters are removed for a coloured backlight that flashes red, green, and blue in quick succession (approximately 100 cycles every second). For example, the liquid crystal might be switched to a transmissive state in the red and green periods but then to a nontransmissive state in the blue period, creating the upshot 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 may be paramount. While many other pieces (save for the bed) are devised to support objects, the chair supports a human form. The term chair was viewed here in the widest sense, from stool to throne to developed items for example the bench and sofa, which may be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously definitive.

The social history of the chair is as intriguing as its history as art and craft. The chair is not just a physical support or aesthetic artwork; it can also be symbolic of social placement. At the past royal courts there were significant distinctions between being seated on a chair with arms, on a chair with a back but without arms, and having to make do with a stool. Since the 20th century, the director’s and manager’s chair has been regarded as iconic of superior status, and even in democratic parliaments the speaker sits on a raised floor.

In its furniture construction, the chair can be employed for a variety of various forms. There are chairs designed to suit man’s age and physical form (the high chair, the wheelchair) and to indicate his standing in society (the executive chair, the throne). During the olden days there were chairs used for birth (birth chairs); since the 20th century, there have been chairs used to die in (the electric chair). We have chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Contemporary lifestyle has designated special chairs in automobiles and aircraft. All these chair kinds has changed to conform to evolving human desires. Because of its significant link with man, the chair exists to its full importance only when used. Although it doesn’t make a difference to one’s appreciation of a cupboard or a chest of drawers whether there is anything inside or not, a chair is really seen and fairly judged with a person using it, for chair and sitter require the other. Thus the various parts of the chair have been given names likened to the parts of the human body: arms, legs, feet, back, and seat.

Because the original work of a chair is to support your body, its credit is valued principally for how well it does fulfill this practical function. In the build of the chair, the chair maker is bound within some static regulation and principal measurements. Under these restrictions, however, the chair maker has marvellous freedom.

The history of the chair extended over a period of several thousand years. There is evidence of societies that created unique chair forms, as seen of the topmost work in the areas of skill and art. Out of those societies, a note must 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 construct of careful design, were known from tomb discoveries. One of the two is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair would have four legs shaped not unlike those of a chosen animal, a curved seat, leading to a sloping back supported over vertical stretchers. In this way a strong triangular form was created. There was from our view no notable differentiation between the creation of Egyptian thrones and chairs for ordinary peasantry. The real variation lied in the intricacy of its ornamentation, in the evidence of expensive inlays. The Egyptian folding stool most likely was developed as an easily packed seat for soldiers. As a camp stool that stool stayed during much later times. But the stool also was made as the use 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, created in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were in the structure of folding stools but are not able to be folded because the seats were worked of wood. The easy build of the folding stool, made of two frames that spin on metal bolts and have a seat of leather or fabric set between them, is seen again but some time later in the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognised of this form is the folding stool, crafted out of ashwood, which is now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The unique Greek chair, the klismos, is seen not as any ancient fossil still around but as seen from a trove of pictorial evidence. The best known is the klismos placed on the Hegeso Stele at the Dipylon burial location by Athens (c. 410 BC). This is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of these legs could be displayed. These odd legs were most likely to have been manufactured with bent wood and were probably bore extreme pressure with the weight of the sitter. The joints holding the legs to the frame of the seat were therefore super stable and were plainly signified.

The Romans emulated the Greek design; some casts of seated Romans are designs of a denser and apparently rather crudely crafted klismos. Both styles, the light and heavy, were popularised within the Classicist time. The klismos design is found in French Empire furniture, in English Regency, and in some special kinds of marked originality in Denmark and Sweden from 1800.

China
The past of the chair in China can not be tracked as far back as the history of chairs in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unbroken folio of drawings and paintings had been protected, displaying the interior and outside of Chinese households and the furniture. Also kept since the 16th century are a number of chairs crafted of wood or lacquered wood, that show an amazing likeness to representations of ancient chairs.

As was the case in Egypt, there existed two standard chair designs in China: a chair of four legs and a folding stool. This four-legged chair has been seen both with or without arms though never without the square seat and straight stiles (upright side supports) to support the back. In one form, it has been seen, the stiles are marginally curved by the arms so as to suit the shape of the S-shaped back splat (the basic upright of the back). The three limbs had been mortised into the yoke-like top rail. Though the style of the Chinese back splat had an influence on English chairs in the Queen Anne period, wooden items that only to a limited ability stabilise corner joints (and are loose in the result) are a design solely to Chinese chairs. The four legs pass through the seat frame, which stops about the rounded staves. Every member is round in section or possesses rounded edges—a left over maybe to the bamboo tradition. The seat is not pleasant and might have had a plaited texture. These chairs required of the sitter to hold themselves stiff and upright; for if too much weight is pushed on the back, the chair has a habit of toppling over. In patriarchal Chinese homes of this period armchairs presumably were reserved only for elderly people in the family, for they were given great respect.

The Chinese folding stool is thought to have travelled to China from the West. It is not dissimilar that much from the Egyptian or Scandinavian folding stools, but it possesses a variation in that the top rail is delicately held to the two legs of the stool with a curved member, which is usually possessing metal mounts. From a Western viewpoint the ultimate effect of both these furniture forms is stylized. The construction and decoration parts are combined in a style that is at the same time naïve and refined. The piecemeal appearance is an outcome of the way that the individual members do not seem to have been affixed by either glue or screws, but have been mortised with one another and held in 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 project a style of chair with a relatively unrefined wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between the layers, stitched to bring up a pattern of little pads. The front board and a related board in the back could be folded after unscrewing some little iron hooks. In this way the chair was a readily portable piece of furniture for traveling which, in the same era, gave the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair can be found in engravings of the interiors of wealthy Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this design of chair may also be seen in countries where Dutch styles of interior decoration and Dutch furniture won favour, it is not held that the design actually originated in The Netherlands. Generally, the legs of the chair were smooth, round in section, and of thin dimensions; they are in some cases baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was crafted in impressive numbers, as surmisable from one of Abraham Bosse’s engravings, in which a whole row of these chairs lined up by a wall. The style asserts itself by its shapely proportions and delicate upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of styles—that is to say, as brought out in Paris around 1750—spread through most of Europe and has been imitated or copied during the mid-20th century. The chair owes this popularity to a combination of relaxation and elegance. The seat adheres to the human body and grants a relaxed seated position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are tiny upholstered pads over the armrests. Smooth transitions are made between seat frame, legs, and back disguise all the joints, which are constructed on craftsmanlike practices despite the absence of stretchers between the legs.

French Rococo chairs and imitations of those are made from wood of fairly thick measurements; but each member is deeply molded, all superfluous wood has been cut away, and more upmarket items may be further embellished with very delicate and decorative carvings. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for all upholstery on the seat, back, and armrests; cane is sometimes used as an alternative to upholstery.

English chairs in the 18th century were more varied in style than the French. The French manner for stylistic uniformity, which came from the highest circles in Paris and Versailles throughout most of France and was popular in large 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
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 products 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 function of a business. Bookkeeping grants the details from which accounts are prepared but is a distinct process, prior to accounting.

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

Management officials, investors, and credit grantors all demand such information: management so as to assess the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to analyse the outcome of business operations and make decisions for buying, holding, and selling securities; and credit grantors in order to judge the financial statements of a business in finding whether to give a loan.

Bits and pieces of financial and numerical recordkeeping have been found for almost every state with a commercial history. Records of commercial contracts were found in the ruins of Babylon, and accounts for both farms and estates had been kept in ancient Greece and Rome. The double-entry manner of bookkeeping started with the progression of the entrepeneurial republics of Italy, and tutorials for bookkeeping were created in the 15th century in some Italian cities.

During 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 records a must-have. The past of bookkeeping, in fact, reflects the past of commerce, industry, and government and, partially, helped in shaping it. The global market of industrial and commercial activity needed better sophisticated decision-making methodology, which in its turn called for higher 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 higher requirement for information; business entities had to show 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 larger.

Although bookkeeping methodology can be very detailed, it is all based on two types of books used in the bookkeeping process—journals and ledgers. A journal contains the daily transactions (sales, purchases, and so forth), and the ledger should have the details of individual accounts. The daily records in the journals are entered in the ledgers.

At the end of every month, generally, an income statement and a balance sheet are made from the trial balance posted within the ledger. The purpose of the income statement or profit-and-loss statement is to give an analysis of any changes that took place in the ownership equity due to the operations of the period. The balance sheet displays the financial situation of the entity at any particular point taken 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.
