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

The typical question customers ask when buying a new projector for the home, office, or classroom is: do I purchase an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two most common projector imaging technologies. With so many brands and types available, it can be challenging for clients to make a decision between these technologies. It comes down to the fact that LCD projectors offer far superior image quality and colour accuracy. The article below explains why DLP projectors struggle with projecting a similar rate of image quality.

It’s like a set of blinds in your room covering your bedroom window. By a twist of a rod you can have the shutters open or closed, depending on if you want to let light in or not. And that is exactly how an LCD projector functions. Each pixel functions like an individual shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as the pros like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the time the projector switches on to when the picture reaches your screen is extremely significant with regard to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by separating it into red, blue and green components, by three mirrors which transfer the coloured light to 3 different LCD panels. The 3 LCD panels make the elements of the image by switching each pixel on and off. The pixels are then projected in a glass prism to form the projector image. Something to understad about LCD projectors is that all three colours are sent onto your screen at once. The way a DLP projector functions is very different and even the way an image shows up is not the same. With DLP, white light from the lamp is directed through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to making 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 produce the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s vision will then combine each coloured element of the image into a single whole image. In LCD projectors, all colours are available all the time to offer top brightness and spectacular colour accuracy. In DLP, only one colour is available at any given time, and so resulting in lower colour brightness and accuracy. Some DLP designers have added a white segment for the colour wheel to improve brightness generally, but this goes and detracts from colour accuracy.

I find in forums all the time that DLP provides a higher contrast ratio and therefore must be better quality. For those uncertain, 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 technology is capable of producing. DLP projectors do possess high contrast specifications when compared to most LCD projectors. At one glance, this appears to be a plus, however, in real life, the true black level is determined by the ambient light in the room while the projector is being utilised. Do not be duped by contrast specifications on websites and in brochures.

When the content you want to see includes moving images, DLP projection technology also creates 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 between the time red, blue and green colours are displayed. LCD projectors do not have this disadvantage because every colour is sent with the others. DLP designers have created 3DLP solutions using 3 chips to fix the colour break up problem, 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 match the balance for the refractive qualities of light. Jump back to high school science, and they taught you how the different colours of light refract differing amounts when projected through the same lens. The downside with DLP projectors is that they utilise the one same panel for the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light in different ways. Generally with a DLP projector, an extra yellow colour will come through above and a superfluous blue will be projected below something as simple as a lone black line. While being built LCD projectors can be set to take away these effects on the projected image, because each colour is projected on separate LCD panels.

The sole true advantage (excluding price) with deciding on a DLP projector is its smaller size and weight. However, this is only relevant with regard to mobility and has to be traded off against the image superiority of LCD projectors. If the result of the picture quality is important to you, then the decision is no-brainer. Choose an LCD projector! LCD projectors will definitely create bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch rose to dominance in sea power during the 17th century, the early yacht was a leisure craft used mostly by royalty and then by the burghers for the canals and then in the protected and unprotected waters of the Low Countries. Yacht racing was incidental, arising as private challenges. English yachting started with King Charles II of England during his exile in the Low Countries. On his return to the English throne in 1660, the city of Amsterdam presented him with 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, reigned 1685–88), made other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 wager. Yachting rose as classy among the affluent and nobility, but after that point the fashion did not last.

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

Yacht racing was first seen in some ordered method 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 the throne in 1820, it was called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht club had been started at Cowes on the Isle of Wight in 1815, and royal funding made the Solent – the strait between the mainland and the Isle of Wight – the continued site of British racing. The society at Cowes became the Royal Yachting Club, likewise at the ascension of George IV. Every member was required to possess boats of at least 20 tons (20,321 kg). Sailing matches for great stakes were held, and the society life was lovely. Ultimately Royal Yachting Club boats grew in size to bigger than 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and went on when the English had control. Sailing was for the most part for leisure and found its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and created a standard of luxury and sophistication for the later yachts in that area from the late 19th century. The first continuing American yacht organisation, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens founded the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts took the style 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 initially greatly affected by the success of America, which was created 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 win at Cowes in 1851. The first yachts were not designed and crafted in a contemporary sense, with just a model being 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 use of the science of aerodynamics do for the design of sails and rigging what such study had done earlier for hulls.

Because most of all sailboats were individually custom-built, there came a need for handicapping boats previous to the one-design class boats were built. Therefore, a rating rule was decreed, which is found in the International Rule, taken on in 1906 and amended 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 standard specifications in length, beam, sail area, and other areas (for an example of a two-person sailboat, see illustration). Racing between such boats can be held on an even par with no handicapping necessary. A prime example is the uniform International America’s Cup Class taken on for racers in the 1992 America’s Cup race.

For the time that yachting belonged largely for the nobility and the wealthy, expense was no issue, and the size of boats developed, in both length and weight. The promotion and desire of smaller craft came in the second half of the 19th century out of the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the hardiness of smaller craft. Following this in the 20th century, particularly 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
After the decade 1840–50, during which steam started to replace sail power in public craft, the steam engine, and later the internal-combustion engine, were used increasingly in pleasure vessels. Sizeable power yachts were progressed to a high standard, and long-distance cruising was a fond activity of the well off. The first power yachts were paddle-wheel boats; those then gave rise to boats powered by the completely submerged screw or propeller type of propulsion. As in the case of naval and merchant boats, auxiliaries with both sail and power were the yacht standard for many years. By the later half of the 20th century, several yachts were still auxiliaries, but the majority were exclusively power yachts containing gasoline or diesel engines.

In the last decade of the 19th century there was a boom in the manufacture of bigger 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 more than 150. The Mayflower, purchased by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and was used in active service for World War II.

As bigger and better quality internal-combustion engines were produced, many big yachts started using them for power. The development of the diesel engine, using heavy oil for fuel, advanced from World War I. In the decade following that, bigger power-yacht manufacture flourished, climaxing in the Orion (1930) at 3,097 tons. During that point the largest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of larger power yachts lessened after 1932, and the trend after that was toward smaller, less pricey boats. Following World War II, lots of small naval boats were bought by private owners for conversion to yachts. By the late 20th century, yachting is a internationally beloved competition enjoyed by thousands of yachtsmen personally manning and maintaining their own small recreational yachts. The popularity of craft and sailors is increasing steadily, not only in the traditional locations along the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be differentiated by the impact they have on the placement of income and wealth. A proportional tax is a tax that places the same relative requirement on all taxpayers—i.e., when tax liability and income increase in the same scale. A progressive tax is characterizable by a larger than proportional rise in the tax onus in regard to the rise in income, and a regressive tax is recognised by a less than proportional growth in the comparative onus. So, progressive taxes are viewed as fighting inequity in income distribution, whereas regressive taxes may result in an increase these inequalities.

The taxes that are often regarded as progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, might become less so in the upper-income group—especially if a taxpayer is able to reduce his tax base by claiming deductions or by leaving out some particular income aspects from his taxable income. Proportional tax rates if applied to lower-income demographics can also be more progressive if such exemptions of a personal nature are declared.

Income measured over the course of a given year might not necessarily come up with the most appropriate measure of taxpaying requirement. For example, transitory increases in income may be saved, and within temporary declines in income a taxpayer might opt to provide for consumption by taking from savings. Ergo, if taxation is regarded along with “permanent income,” it should be less regressive (or more progressive) than when it is held in comparison with annual income.

Sales taxes and excises (excepting luxuries) are usually regressive, because the dissemination of personal income consumed or spent for a specific good declines as the rate of personal income is raised. Poll taxes (also called head taxes), levied as a set amount per capita, clearly are regressive.

It is difficult to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to the uncertainty surrounding 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 for the most part on whether a national or a subnational (that is, provincial or state) tax is being determined.

In considering the economic effects of taxation, it is essential to differentiate between differing points of tax rates. The statutory rates are nominated in law; often these are marginal rates, but sometimes they are median rates. Marginal income tax rates indicate the fraction of incremental income that is taken by taxation when income is increased by one dollar. Therefore, if tax onus rises by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax regulations commonly contain graduated marginal rates—i.e., rates that increase as income increases. Careful analysis of marginal tax rates should take into account provisions other than the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) reduces by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points higher than specified in the statutory rates. Since marginal rates specify how after-tax income increases or decreases in response to changes in before-tax income, they are the necessary ones for considering incentive effects of taxation. It is even more complicated to know the marginal effective tax rate to apply to income from business and capital, as it may be dependant on factors such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem shows that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates indicate the fraction of total income that is required 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 increases with income. Average income tax rates commonly rise with income, both because personal allowances are granted for the taxpayer and dependents and because marginal tax rates are graduated; on the other side of things, preferential treatment of income received fundamentally by high-income households might dampen these effects, forcing regressivity, as shown by average tax rates that fall as income rises.

The Development of Data Projectors

The LCDs utilised in projection systems are most often small reflective or transmissive panels illuminated by a bright arc lamp source. A line of lenses enlarges the reflected or transmitted image and displays it on a screen. In front-projection systems the LCD is set on the side of the screen as the viewer, while in rear-projection systems the screen is illuminated from behind. Projectors of greater expense and capacity might use three separate LCD panels, creating separate red, green, and blue images that blend to form a coloured picture on the screen.

The increasing demand for pictographic displays has granted a special emphasis on the switching speed of liquid crystals. This has demanded the creation of objects employing smectic liquid crystals, certain ones of which give a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most progressive smectic device. In 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 in the layers the molecules are on a slant, as illustrated in the figure. The host liquid crystal has optically active molecules, and a scarcely perceptible result of the optical activity and the slant of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, likeable 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. Therefore, there has to be 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 correct sign can reverse the direction of this dipole in tens of microseconds and by doing so reverse the tilt direction of the molecules. The consequential change in optical properties can cause a change from light to dark in the case that one or more polarizers are employed.

SSFLC devices have been marketed for larger passive-matrix presentations, but their expense and intricacy has stopped them from having any significant impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some promise for use as elements in projection systems or as viewfinders in digital cameras. Their speedy reacting allows them to be employed in time-sequential colour systems, in which high cost colour filters are emulated with a coloured backlight that flashes red, green, and blue in quick speed (approx 100 cycles in a second). For example, the liquid crystal can be switched to a transmissive state between the red and green periods and then to a nontransmissive state during the blue period, with the result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Of all furniture items, the chair might be the most important. While the majority of other items (apart from the bed) are designed to support objects, the chair supports the human form. The term chair is intended to be said here in the widest sense, from stool to throne to derivative items including the bench or sofa, which may be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly definitive.

The social history of the chair is as intriguing as its history as art and craft. The chair is not simply a physical support and/or aesthetic object; it historically was symbolic of social standing. Within the past royal courts there were plain differences between having a chair with arms, sitting on a chair with a back but without arms, or worse having to squat on a stool. In the 20th century, the director’s and manager’s chair has become iconic of superior dignity, as well as in democratic government meeting the speaker sits on a high-set platform.

As its furniture creation, the chair is used for a wealth of different purposes. There are chairs created to attend to man’s age and physical abilities (the high chair, the wheelchair) and to indicate his position in society (the executive chair, the throne). In past days there were chairs to be born in (birth chairs); in the 20th century, there have been chairs used for ending life (the electric chair). There are chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. We make chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Modern day living has derived unique chairs for use in automobiles and aircraft. Each and every one of these chair shapes has adapted to match to differing human requirements. For its particular importance with man, the chair appears to its full significance only when utilised. While it doesn’t make any difference to one’s appreciation of a cupboard or a chest of drawers whether there might be items inside or not, a chair is understood and evaluated by a person sitting in it, for chair and sitter suit the other. Thus the different limbs of a chair were given labels like the parts of the human shape: arms, legs, feet, back, and seat.

Because the principal role of a chair is to support our body, its credit is evaluated firstly for how fully it does fulfill this practical purpose. In the design of the chair, the builder is restricted within certain static regulation and principal measurements. Inside these limits, however, the chair maker has awesome freedom.

The history of the chair lasted over dates of several thousand years. There are cultures that had significant chair shapes, expressions of the highest work in the spheres of skill and creativity. Within these societies, a note can 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the upshot of skilled craft, were seen from discoveries made in tombs. The first one of the two is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair had four legs formed similar to those of a chosen animal, a curved seat, and leading to a sloping back supported by vertical stretchers. In this design a durable triangular structure was made. There was apparently no marked difference from the design of Egyptian thrones and chairs for regular non-royals. The only variation existed in the intricacy of its ornamentation, in the evidence of more costly inlays. The Egyptian folding stool probably was developed for an easily portable seat for army. As a camp stool that stool continued until much later points in time. But the stool also then was created as the role of a ceremonial seat, its technical job as a folding stool being forgotten. This can from today be noted, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They are in the form of folding stools but cannot be folded as the seats were created out of wood. The simplistic manufacture of the folding stool, being of two frames that spin on metal bolts and hold a seat of leather or fabric set between them, then came again somewhat later from the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognised of those is the folding stool, 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 object still in form but as seen in a large amount of pictorial material. The best recognised is the klismos displayed on the Hegeso Stele at the Dipylon burial location in outer Athens (c. 410 BC). It is a chair with a backward-sloping, curved backboard and four curving legs, but only two of those legs were seen. These creative legs were understood to have been executed from bent wood and were probably bore huge pressure under the weight of the sitter. The joints joining the legs to the frame of the seat were therefore very strong and were particularly signified.

The Romans borrowed from the Greek chair; some casts of seated Romans are examples of a more heavyset and which appear to be a slightly less intricately built klismos. Both kinds, the light and heavy, were brought back as part of the Classicist epoch. The klismos design is known in French Empire furniture, in English Regency, and in special types of considerable iconicism around Denmark and Sweden around 1800.

China
The ancestry of the chair in China isn’t able to be followed as far back as that of Egypt and Greece. From the Tang dynasty (AD 618–907) a full folio of drawings and paintings has been kept, displaying the insides and outer parts of Chinese houses and the furniture. Another preservation from the 16th century are a trove of chairs of wood or lacquered wood, that show an intriguing likeness to pictures of older chairs.

As in Egypt, there existed two standard chair designs in China: a chair of four legs and a folding stool. That four-legged chair can be designed both with or without arms however never without the square seat and straight stiles (straight side supports) to give support to the back. In one type, it must be said, the stiles could be lightly curved above the arms so as to sit correctly with the angle of the S-shaped back splat (the centre upright of a chairback). Together, the three parts had been mortised in the yoke-like top rail. While the innovation of this back splat later had an introduction for English chairs of the Queen Anne period, wooden items that could only to a particular limit embolden corner joints (and then are loose additionally) indicate a signature signatory to Chinese chairs. The four legs pass through the seat frame, which finishes upon the rounded staves. All members are round in section or possesses rounded edges—referable perchance to the bamboo tradition. The seat is not pleasant and may have a plaited seat. These chairs required of the sitter to stay stiff and upright; for if too much pressure is forced on the back, the chair has a way of toppling over. In patriarchal Chinese houses of this epoch armchairs presumably were reserved only for elderly persons in the family, for they were greatly respected.

The Chinese folding stool is believed to have travelled to China from the West. It is akin much from the Egyptian or Scandinavian folding stools, but it possesses a variation in that the top rail is prettily joined to the two legs of the stool by using a curved member, which is often designed with metal mounts. From a Western point of view the resulting effect of these furniture forms is stylized. The structure and aesthetic aspects are combined in a way that is all at once both naïve and refined. The pieced-together appearance is an upshot of the way that the individual items do not look to have been put together by use of either glue or screws, but had been mortised onto one another and locked into its place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also had its name on the chair. Paintings display a style of chair with a relatively crude wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing in between the layers, stitched to produce a pattern of small pads. The front board and a similar board at the back could be folded after unscrewing some tiny iron hooks. In this way the chair was an easily portable piece of furniture for traveling which, during the same era, held the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair is found in engravings of the inside of rich Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this design of chair may also be found in countries where Dutch styles of interior decoration and Dutch furniture won acclaim, it is not determined that the form actually was born in The Netherlands. Typically, the legs of the chair are smooth, round in section, and of slim shape; they are in some cases baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was crafted in vast numbers, as surmisable from one of Abraham Bosse’s engravings, in which there is an entire row of this kind of chairs lined up against a wall. The style asserts itself with its harmonious proportions and fine upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of styles—that was, as progressed in Paris around 1750—spread through most of Europe and has been imitated or copied into the mid-20th century. The style owes such popularity to a combination of comfort and charm. The seat adheres to the human body and permits 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 made between seat frame, legs, and back cover all the joints, which are stable, constructed on craftsmanlike principles even with the absence of stretchers between the legs.

French Rococo chairs and imitations thereof use wood of relatively thick dimensions; but all members are deeply molded, all extraneous wood has been sanded away, and finer designs would be further embellished with special delicate and decorative carvings. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry should be used for all the upholstery on the seat, back, and armrests; cane is sometimes used as an alternative to upholstery.

English chairs of the 18th century were more varied in design than the French. The French taste for stylistic uniformity, which disseminated from the aristocratic circles in Paris and Versailles through most of France and was popularised 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 commonly known and was widely distributed throughout the world.

Late 18th to 20th century
Within 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 styles 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, indicate that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the charting of the money values of the operation of a business. Bookkeeping grants the numbers from which accounts are written but is a separate process, required prior to accounting.

Predominantly, bookkeeping grants two kinds of information: (1) the current value, or equity, of a business and (2) any changes in value—profit or loss—taking placement in the enterprise over a single time period.

Management officials, investors, and credit grantors all need such information: management to assess the outcomes 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 about buying, holding, and selling securities; and credit grantors so as to regard the financial statements of a business in deciding whether to give a loan.

Evidence of financial and numerical records have been uncovered for almost every group of people with a commercial history. Records of commercial contracts have been discovered in the archaelogical digs of Babylon, and accounts for both farms and estates had been created in ancient Greece and Rome. The double-entry manner of bookkeeping started with the furthering of the commercial republics of Italy, and tutorial manuals for bookkeeping were created within the 15th century in some Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made perfect financial books a paramount factor. The ancestry of bookkeeping, in fact, resembles the past of commerce, industry, and government and, partially, assisted to shape it. The global market of industrial and commercial activity needed better sophisticated decision-making procedures, which itself called for more sophistication in the selection, classification, and presentation of information, increasingly with the progression of computers. Taxation and government regulation became more important and resulted in higher need for information; businesses had to show available information to go with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew, and the demand for bookkeeping for their inner departmental operations became higher.

Though bookkeeping methodology can be very detailed, all of it is based on two kinds of books utilised in the bookkeeping process—journals and ledgers. A journal should have the daily transactions (sales, purchases, and so on), and the ledger should have the information of individual accounts. The daily records kept in the journals are entered in the ledgers.

Each month, by general practice, an income statement and a balance sheet are constructed from the trial balance posted from the ledger. The purpose of the income statement or profit-and-loss statement is to present an analysis of those changes that have taken place in the enterprise equity as a result of the events of the period. The balance sheet provides the financial position of the corporation at the particular point with regard to assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

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

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

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

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

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

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

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

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

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

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

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

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