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

The most common question heard when purchasing 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, short for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many company brands and types available, it can be overwhelming for the buyer to decide between both technologies. It comes down to the fact that LCD projectors provide superior image quality and colour accuracy. The next part of this article will tell you why DLP projectors struggle with bringing up the same rate of image quality.

Think of a set of blinds in your room covering your bedroom window. By twisting a rod you can have the shutters open or closed, according to if you want to let light in or not. This is exactly how an LCD projector works. Each pixel functions like an individual shutter on a set of blinds to either send light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as experts 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 content reaches your screen is ultimately significant for image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by cutting it into red, blue and green components, by three mirrors which direct the coloured light to 3 different LCD panels. The 3 LCD panels make the elements of the image by processing each pixel on and off. The pixels are then simultaneously processed in a glass prism to create the projector image. A point to remember about LCD projectors is that all three colours are projected onto your wall at once. The way a DLP projector functions is widely different and even the final product of how an image looks is not the same. With DLP, white light from the lamp is projected through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to making an image creates a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to construct the image elements. The elements of the image are sent in sequence on the screen, one colour at a time. The viewer’s eye will then combine each coloured element of the image into the total image. From LCD projectors, all colours are available all the time to create the highest brightness and great colour accuracy. In DLP, only one colour is available at once, resulting in lower colour brightness and accuracy. Some DLP developers have included a white segment into the colour wheel to improve overall brightness, but this then damages colour accuracy.

I see in forums all the time that DLP provides a higher contrast ratio and ergo must be better 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 system is capable of. DLP projectors do have high contrast specifications as compared to the majority of LCD projectors. At a glance, this seems to be an advantage, however, in real life, the true black level is determined by the ambient light in the room while the projector is utilised. Do not be fooled by contrast specifications on websites and in brochures.

When the content you plan to see needs moving images, DLP projection technology can also create image marks, or ‘artifacts’. The most commonplace artifact that a DLP projector forms 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 projected. LCD projectors do not have this downside because all the colours are delivered at the same time. DLP developers have developed 3DLP solutions using 3 chips to resolve the colour break up problem, but the expense of these projectors make them almost impossible for many 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 remember how the various colours of light refract different amounts when directed through the same lens. The problem 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 obviously not the same and refract light differently. Generally with a DLP projector, some extra yellow colour will be projected above and some extra blue will come up below an image as simple as a straight black line. While being built LCD projectors can be adapted to minimize these effects on the projected image, as each colour is directed on a separate LCD panels.

The sole real buy point (excluding price) with deciding on a DLP projector is its smaller size and weight. However, this is only relevant for transporting the device and has to be traded off against the image advantages of LCD projectors. If the result of the picture quality is important to you, then the solution is no-brainer. Go for an LCD projector! LCD projectors will constantly show 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 pleasure craft used first by royalty and then by the burghers in the canals as well as the protected and unprotected waters of the Low Countries. Racing yachts was incidental, coming out of private games. English yachting originated with King Charles II of England during his exile in the Low Countries. On his return to the English royalty in 1660, the city of Amsterdam sent him a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he then named Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), built more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 wager. Yachting became popular for the wealthy and royalty, but after that point the habit did not last.

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

Yacht racing was first seen in some organized method on the Thames in the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV ascended to the throne in 1820, it came to be known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht society had been formed 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 setting of British yachting. The club at Cowes became the Royal Yachting Club, likewise at the accession of George IV. All members were required to have boats of at least 20 tons (20,321 kg). Sailing races for high stakes were held, and the social life was wonderful. Ultimately Royal Yachting Club boats were raised in size to over 350 tons.

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

Kinds of sailboats
The Early sailing yachts took the lines of such naval craft as brigantines, schooners, and cutters from the 17th century until the latter half of the 19th century. The design of large yachts was initially heavily impacted by the win of America, which was drawn by George Steers for a syndicate headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its win at Cowes in 1851. The first yachts were not designed and built in today’s sense, with merely a model being used. Not until the later half of the 19th century did what was called naval architecture come about. Not until the 1920s did the application of the research of aerodynamics do for the structure of sails and rigging what it had previously done for hulls.

Because almost all sailboats had to be individually built, there came a desire for handicapping boats as this was previous to the one-design class boats were made. Thus, a rating rule was decreed, which resulted in the International Rule, taken on in 1906 and amended in 1919. Today, one of the most rapidly blossoming areas in the field of sailing is that of one-design class boats. All boats in a one-design class are built to the same dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing between such boats can be had on an even keel with no handicapping at all. A great example is the standard International America’s Cup Class taken on for racers in the 1992 America’s Cup race.

So long as yachting was an activity primarily for the royal and the rich, expense was no problem, and the size of boats developed, in both length and weight. The rise and preference of smaller craft occurred in the latter half of the 19th century in the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the value of less sizeable yachts. Later in the 20th century, for the larger part after World War II, smaller racing and recreational yachts became commonplace, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, at which point steam started to replace sail power in market vessels, the steam engine, and later the internal-combustion engine, were used increasingly in pleasure boats. Bigger power yachts were developed to a high degree, and long-distance travel became a preferred pastime of the affluent. The first power yachts were paddle-wheel boats; these then gave way to yachts powered by the fully submerged screw or propeller type of propulsion. As in the case of naval and merchant boats, auxiliaries carrying both sail and power were the yacht archetype for a number of years. By the later half of the 20th century, several yachts were still auxiliaries, but the larger part were exclusively power yachts with gasoline or diesel engines.

During the last decade of the 19th century there was a push in the construction of more sizeable steam yachts. In particular of these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was manned 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 gave active service during World War II.

As bigger and better quality internal-combustion engines were created, many bigger craft were using them for power. The creation of the diesel engine, using heavy oil for fuel, advanced for World War I. From the decade following, bigger power-yacht creation blossomed, climaxing in the Orion (1930) at 3,097 tons. From that point the biggest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of big power boats lessened in 1932, and the trend thereafter was toward smaller, less pricey craft. After World War II, a lot of small naval craft were bought by private owners for conversion to yachts. In the late 20th century, yachting has become a internationally loved sport enjoyed by thousands of yachtsmen personally manning and upkeeping their own small pleasure yachts. The popularity of boats and owners has increased steadily, not only in the traditional areas by the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are distinguished by the effect they have on the distribution of income and wealth. A proportional tax is a kind that applies the same relative requirement on all the taxpayers—i.e., where tax liability and income increase in equal scale. A progressive tax is characterized by a greater than proportional rise in the tax liability in regard to the growth in income, and a regressive tax is recognisable by a less than proportional rise in the relative liability. So, progressive taxes are thought of as reducing the lack of equality in income distribution, but regressive taxes are believed to result in increasing these inequalities.

The taxes that are usually 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 class—particularly if a taxpayer is able to reduce his tax base by nominating deductions or by leaving out some income elements from his taxable income. Proportional tax rates that are applied to lower-income demographics could also be more progressive if such personal exemptions are claimed.

Income measured over the period of a year might not absolutely provide the most accurate measure of taxpaying status. For example, transitory growth in income can be saved, and in temporary declines in income a taxpayer may decide to provide for consumption by taking from savings. So, if taxation is regarded with “permanent income,” it should be less regressive (or more progressive) than if held in comparison with annual income.

Sales taxes and excises (save those on luxuries) tend to be regressive, because the portion of own income consumed or spent for a specific good lowers as the rate of personal income rises. Poll taxes (also called head taxes), levied as a flat amount per capita, patently are regressive.

It is difficult to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of a lack of certainty around the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden is dependant crucially 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 important to differentiate between varied ideas of tax rates. The statutory rates are specified in the legislation; often these are marginal rates, but occasionally they are average rates. Marginal income tax rates signify the fraction of incremental income that is taken by taxation when income grows by one dollar. Thus, if tax onus increases by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax laws usually contain graduated marginal rates—i.e., rates that rise as income grows. Careful analysis of marginal tax rates must consider provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points greater than indicated within the statutory rates. Since marginal rates indicate how after-tax income moves in response to changes in before-tax income, they are the relevant ones for appraising incentive effects of taxation. It is even more difficult to nominate the marginal effective tax rate applied to income from business and capital, because it may be dependant on such considerations 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 display the fraction of total income that is required in taxation. The pattern of average rates is the one that is important for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates usually increase with income, both because personal allowances are allowed for the taxpayer and dependents and due to that marginal tax rates are graduated; on the flip side, preferential treatment of income received for the most part by high-income households may swamp these effects, forcing regressivity, as shown by average tax rates that lessen as income increases.

The Development of Data Projectors

The LCDs utilised for projection systems are typically small reflective or transmissive panels lit by a bright arc lamp source. A series of lenses expands the reflected or transmitted image and displays it on a screen. With front-projection systems the LCD is set on the same side of the screen as the viewer, while in rear-projection systems the screen is lit from behind. Projectors of higher cost and capacity can utilise three separate LCD panels, casting separate red, green, and blue images that blend to form a coloured picture on the screen.

The growth in demand for visual displays has granted a growing emphasis on the switching speed of liquid crystals. This has led to the invention of devices build with smectic liquid crystals, certain ones of which have a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is in the current day the most complex smectic device. In it the liquid crystal molecules are cast in layers perpendicular to the substrate planes, which are differentiated by one or two micrometres, and inside the layers the molecules are on a tilt, as displayed in the figure. The host liquid crystal holds optically active molecules, and a slight consequence of the optical activity and the slant of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, analogous to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and in the plane of the layers. So, there exists a permanent charge separation through 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 so reverse the tilt direction of the molecules. The consequential 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 large passive-matrix presentations, but their expensiveness and complex detail has impeded them from creating any remarkable impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some promise for use as aspects in projection systems or as viewfinders in digital cameras. Their fast responding allows them to be made use of in time-sequential colour systems, in which expensive colour filters are taken out for a coloured backlight that flashes red, green, and blue in fast pace (around 100 cycles per second). For example, the liquid crystal can be switched to a transmissive state between the red and green periods but to a nontransmissive state in the blue period, with the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From each of the furniture pieces, the chair might be primary. While most of the other items (save for the bed) are designed to support objects, the chair supports your human form. The term chair should be looked upon here in the common sense, from stool to throne to complex types including the bench or sofa, which might be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently distinguished.

The social history of the chair is as exciting as its history as an art and craft. The chair is not simply a physical support and/or aesthetic piece; it can also be a signifier of social hierarchy. From the old royal courts there were clear signifiers between sitting on a chair with arms, on a chair with a back but without arms, or worse having to squat on a stool. From the past century, the director’s and/or manager’s chair has been an identifier of superior standing, like in democratic government debate the speaker sits on a raised platform.

As its furniture purpose, the chair can be utilised for a range of various forms. There are chairs manufactured to match man’s age and physical capabilities (the high chair, the wheelchair) and for his status in society (the executive chair, the throne). In past days there were chairs for birthing (birth chairs); during 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. We can make chairs that can be folded up, chairs on wheels, and chairs on runners.

Our modern lifestyle has derived unique chairs for use in automobiles and aircraft. All these chair kinds have been adapted to match to differing human needs. For its unique association with man, the chair exists to its full purpose only when in employ. While it is not relevant to one’s appreciation of a cupboard or a dresser drawers if there might be things inside or not, a chair is really understood and fairly judged with a person using it, for chair and sitter need one another. Thus the various areas of the chair were given labels like the parts of our human form: arms, legs, feet, back, and seat.

Because the obvious purpose of your chair is to support your body, its credit is tested primarily from how fully it fulfills this practical use. In the design of a chair, the designer is restricted with some static regulations and principal measurements. Within these boundaries, however, the chair builder has awesome freedom.

The history of the chair extends over an era of several thousand years. There were societies that had unique chair shapes, as expressions of the highest craft in the spheres of technique and aesthetics. Within these such civilisations, special 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 reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the result of expert design, were found from tombs. The first of these two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have had four legs shaped as akin to those of some animal, a curved seat, and a sloping back supported with vertical stretchers. In this design a durable triangular structure was made. There was in our knowledge no particular change from the construction of Egyptian thrones and chairs for common non-royals. The simple difference existed in the kind of ornamentation, in the particulars of more costly inlays. The Egyptian folding stool in all likelihood was created to be an easily stored seat for soldiers. As a camp stool the kind persevered til much later points. But the stool then was created for the use of a ceremonial seat, its technical task as a folding stool neglected or forgotten. This can from today’s evidence be found, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They were constructed in the structure of folding stools but can not be folded as the seats are worked of wood. The simple manufacture of the folding stool, composed of two frames that cycle on metal bolts and bear a seat of leather or fabric held between them, appeared at some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of this form is the folding stool, crafted out of ashwood, now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is recognised not from any ancient item still in form but found in a variety of pictorial objects. The most well known is the klismos placed on the Hegeso Stele at the Dipylon burial area outside Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of them were seen. These strange legs were thought to have been manufactured with bent wood and were probably subjected to huge pressure with the weight of the sitter. The joints joining the legs to the frame of the seat were therefore very durable and were overtly drawn.

The Romans emulated the Greek style; some models of seated Romans are evidence of a denser and in appearance rather less delicately designed klismos. Both designs, the light and heavy, were popularised as part of the Classicist time. The klismos design can be seen in French Empire design, in English Regency, and in special kinds of considerable originality of Denmark and Sweden during 1800.

China
The history of the chair in China cannot be traced as long as the history of chairs in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) a full collection of images and artworks was kept safe, with images of the insides and outer parts of Chinese houses and the kinds of furniture. Kept also since the 16th century are a collection of chairs constructed from wood or lacquered wood, that bear an astonishing familiarity to images of ancient chairs.

As was the case in Egypt, two particular chair forms existed in China: a chair having four legs and a folding stool. That four-legged chair has been designed both with and without arms however always having the square seat and straight stiles (vertical side supports) to firm the back. In one design, it has been seen, the stiles could be delicately curved on top of the arms so as to conform to the shape of the S-shaped back splat (the basic upright of a back). All three sections had been mortised in the yoke-like top rail. Although the innovation of the Chinese back splat later had an influence on English chairs from the Queen Anne period, wooden sections that only to a particular ability stabilise corner joints (and were loose additionally) signify an element signatory to Chinese chairs. The four legs sit through the seat frame, which ends about the rounded staves. Each member is round in section or is given rounded edges—references perhaps to the bamboo tradition. The seat is unpleasant to sit in and may have had a plaited form. These chairs required the sitter to hold themselves stiff and upright; if too much pressure is forced on the back, the chair has a way of falling over. In patriarchal Chinese homes of this epoch armchairs presumably were reserved for older persons, for they were greatly esteemed.

The Chinese folding stool is thought to have travelled to China from the West. It does not vary so very much from the Egyptian or Scandinavian folding stools, but it possesses a change in that the top rail is elegantly affixed to the two legs of the stool in a curved member, which is often provided with metal mounts. From a Western point of view the resulting effect of these two furniture designs is stylized. The construction and decoration aspects are combined in a manner that is at the same time naïve and refined. The pieced-together appearance is an outcome of the manner that the individual items do not appear to have been adjoined by either glue or screws, but were mortised on one another and fixed in place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also left its mark on the chair. Paintings display a type of chair with a relatively brusque wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between the layers, stitched to bring out a pattern of small pads. The front board and a similar board from the back could be folded after loosening some little iron hooks. In this way the chair was an easily portable piece of furniture in traveling which, in the same time, had the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair is evidenced in engravings of the interiors of affluent Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this kind of chair is also found in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not certain that the innovation actually was instigated in The Netherlands. Normally, the legs of the chair are smooth, round in section, and of slender measurements; they are in some cases baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was produced in considerable numbers, as evidenced from one of Abraham Bosse’s engravings, in which a whole row of those chairs lined up against a wall. The design asserts itself by its harmonious proportions and delicate upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that was, as progressed in Paris around 1750—disseminated through most of Europe and has been imitated or copied in the mid-20th century. The style owes such popularity to a combination of relaxation and delicacy. The seat conforms to the human body and grants a relaxed seated position. The back is bow-shaped, the legs curved. Typically the seat and back are upholstered, and there are little upholstered pads covering the armrests. Smooth transitions achieved between seat frame, legs, and back cover all the joints, which are strongly constructed on craftsmanlike methodology despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them are made from wood of fairly thick measurements; but all members are deeply molded, all extra wood has been taken away, and more expensive chairs would be further embellished with special delicate and decorative woodwork. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry might be used for all the upholstery on the seat, back, and armrests; crosshatched cane is occasionally used as an alternative to upholstery.

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

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

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

In cheaper 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 function of a business. Bookkeeping provides the figures from which accounts are drafted but is a different process, prerequisite to accounting.

Fundamentally, bookkeeping provides two kinds of information: (1) the current value, or equity, of the entity and (2) changes in value—profit or loss—taking place in the entity over a given period.

Management officials, investors, and credit grantors all need to have this kind of information: management in order to analyse the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to interpret the results of business operations and make decisions about buying, holding, and selling securities; and credit grantors to regard the financial statements of an enterprise in deciding whether to accept a loan.

Evidence of financial and numerical record charts have been seen for just about every nation with a commercial backbone. Records of business contracts have been found in the archaelogical digs of Babylon, and accounts for both farms and estates had been archived in ancient Greece and Rome. The two-entry process of bookkeeping came with the development of the entrepeneurial republics of Italy, and instruction books for bookkeeping were created within the 15th century in various Italian cities.

Within 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 recordkeeping a paramount factor. The ancestry of bookkeeping, in fact, resembles closely the history of commerce, industry, and government and, in some part, assisted in shaping it. The worldwide spread of industrial and commercial activity called for greater sophisticate decision-making methods, which in turn needed higher sophistication in the selection, classification, and presentation of information, more so with the assistance of computers. Taxation and government regulation became more important and resulted in greater requirement for information; entities 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 become larger, and the requirement for bookkeeping for their inner operations became larger.

While bookkeeping procedures can be extremely complex, all of it is based on two kinds of books used in the bookkeeping procedure—journals and ledgers. A journal should have the daily transactions (sales, purchases, and such), and the ledger has the details of individual accounts. The daily records kept in the journals are written in the ledgers.

At the end of every month, by general practice, an income statement and a balance sheet are made from the trial balance posted in the ledger. The point of the income statement or profit-and-loss statement is to display an analysis of any changes that happen in the ownership equity due to the transactions of the period. The balance sheet gives the financial situation of the company 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 resulted in 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 wish 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.
