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

The most typical question customers ask when purchasing a new projector for the home, office, or classroom is: would I buy an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two most common projector imaging technologies. With so many brands and types available, it can be overwhelming for clients to pick between the two technologies. The fact is that LCD projectors give far superior image quality and colour accuracy. The following article tells you why DLP projectors struggle with bringing up an equal standard of image quality.

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

How the light source is processed from when the projector is switched on to when the picture reaches your screen is vitally significant to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by cutting it into red, blue and green components, by three mirrors which direct the coloured light to 3 individual LCD panels. The 3 LCD panels cast the elements of the image by processing each pixel on and off. The pixels are then projected in a glass prism to deliver the projector image. An important point to know about LCD projectors is that all three colours are directed onto your wall at once. The way a DLP projector runs is very different and even the final product of how an image comes out 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 projecting an image requires a sequence of red, blue and green light. The millions of micro mirrors described 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 offer the top level of brightness and great colour accuracy. In DLP, just one colour is available at a time, causing lower colour brightness and accuracy. Some DLP designers have included a white segment in the colour wheel to improve all over brightness, but this goes and detracts from colour accuracy.

I read in forums all the time that DLP has 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 machine is able to produce. DLP projectors do offer high contrast specifications compared to many LCD projectors. At a glance, this appears to be a plus, however, in truth, the true black level is determined by the ambient light in the room while the projector is being used. Do not be tricked by contrast specifications on websites and in brochures.

When the content you plan to see requires moving images, DLP projection technology can also have image imperfections, or ‘artifacts’. The most often seen artifact that a DLP projector displays with moving images is colour break up. Colour break up is to be expected in DLP systems because moving images keep changing between the time red, blue and green colours are shone. LCD projectors do not have this problem because the colours are sent at the same time. DLP builders have come up with 3DLP solutions using 3 chips to solve the colour break up artifacts, but the expense of these projectors make them not practical for the large part of businesses and consumers.

Another difference between LCD and DLP is how they make up for the refractive qualities of light. Remember back to high school science, and recall how the various colours of light refract various amounts when directed through the same lens. The downfall 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 different and refract light in a different way. Usually with a DLP projector, a spill of yellow colour will come up above and a superfluous blue will be projected below an image as simple as a straight black line. In building LCD projectors can be set to take away these effects on the projected image, because each colour is refracted on its own LCD panels.

The one real advantage (excluding price) with taking a DLP projector is its smaller overall size and weight. However, this is only relevant in regard to transporting the device and must be traded off against the image plusses of LCD projectors. If resulting picture quality is important to you, then the answer is a no-brainer. Take an LCD projector! LCD projectors will constantly create bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

As the Dutch found dominance in sea power during the 17th century, the first yacht had been a leisure craft used first by royalty and later by the burghers for 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 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 presented him with a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he then named Mary. Charles and his brother James, the duke of York (James II, sovereign 1685–88), ordered for other yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 wager. Yachting was found to be popular for the wealthy and aristocracy, but after that period the habit did not last.

The first yacht club in the British Isles, the Water Club, was started in about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and had large naval panoply and gravity. The closest thing to racing was the “chase,” when the “fleet” pursued a fictional enemy. The club persisted, mostly as a social club, until 1765, and in 1828, after conglomerating with other organisations, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some stipulated fashion on the Thames around 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 was called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been formed 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 continuing setting of British racing. The organisation at Cowes became the Royal Yachting Club, likewise at the ascension of George IV. Every member was required to have boats of at least 20 tons (20,321 kg). Sailing matches for large bids were held, and the society life was lovely. Ultimately Royal Yachting Club boats were raised in size to more than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and went on when the English had dominance. Sailing was largely for fun and found its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and created a minimum of luxury and elegance for the later yachts in that area from the late 19th century. The first continuing American yacht organisation, the Detroit Boat Club, was instigated 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 lines of such naval craft as brigantines, schooners, and cutters from the 17th century through the latter half of the 19th century. The style of sizeable yachts was first heavily affected by the success of America, which was created by George Steers for a group headed by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its win at Cowes in 1851. The first yachts were not designed and built in a contemporary sense, with only a model for an outline. Not until the later half of the 19th century did what was known as naval architecture come into action. Not until the 1920s did the use of the research of aerodynamics do for the structure of sails and rigging what such science had previously done for hulls.

Because nearly all sailboats had been individually built, there was a desire for handicapping boats as this was previous to the one-design class boats were made. Hence, a rating rule was written, which is found in the International Rule, taken on in 1906 and revised in 1919. In the present day, one of the rapidly blossoming areas in the field of sailing is that of one-design class boats. All boats in a one-design class are manufactured to standard specifications in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing for 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 adopted for yachts in the 1992 America’s Cup race.

So long as yachting was an activity primarily for the aristocracy and the affluent, expense was no issue, and the size of boats grew, in both length and weight. The rise and desire of smaller craft happened 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 journey around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the value of smaller craft. Following this in the 20th century, particularly after World War II, smaller racing and recreational yachts became more popular, down to the dinghy, a preferred 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, at which point steam started to replace sail power in commercial boats, the steam engine, and later the internal-combustion engine, were favoured increasingly in pleasure craft. Large power yachts were developed to a high element, and long-distance sailing became a favoured pastime of the rich. The early power yachts were paddle-wheel boats; those then made way to boats powered by the fully submerged screw or propeller kind of propulsion. As in the case of naval and merchant craft, auxiliaries possessing both sail and power were the yacht standard for a number of years. By the second half of the 20th century, many yachts were still auxiliaries, but the larger part were exclusively power yachts containing gasoline or diesel engines.

During the last decade of the 19th century there was a boom in the construction of bigger steam yachts. In particular among these was the Mayflower (1897) of 2,690 tons, that had triple-expansion engines, twin screws, and a compartmented iron hull, and was operated by a crew of over 150. The Mayflower, bought by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and saw active service during World War II.

As larger and more dependable internal-combustion engines were produced, many big yachts started using them for power. The development of the diesel engine, using heavy oil for fuel, was furthered during World War I. During the decade that followed, large power-yacht creation grew, climaxing in the Orion (1930) at 3,097 tons. From that period the biggest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of big power boats lessened after 1932, and the trend from then was toward smaller, less expensive craft. After World War II, a lot of small naval boats were sold to private owners for conversion to yachts. In the late 20th century, yachting is a internationally beloved sport enjoyed by thousands of yachtsmen personally manning and keeping their own small leisure craft. The popularity of boats and sailors is increasing steadily, not only in the traditional places along the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be distinguished by the impact they have on the distribution of income and wealth. A proportional tax is the kind that puts the same relative burden on all the taxpayers—i.e., when tax liability and income move in the same proportion. A progressive tax is characterized by a greater than proportional growth in the tax liability in regard to the rise in income, and a regressive tax is characterized by a less than proportional rise in the comparative onus. Hence, progressive taxes are viewed as fighting a lack of equality in income distribution, while regressive taxes are seen to have the effect of increasing these inequalities.

The taxes that are generally thought to be progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, could become less so in the upper-income class—particularly if a taxpayer is able to lower his tax base by declaring deductions or by leaving out certain income elements from his taxable income. Proportional tax rates which are applied to lower-income demographics could also be more progressive if exemptions of a personal nature are claimed.

Income measured over the course of a given year does not necessarily come up with the most suitable measure of taxpaying requirements. For example, transitory rises in income may be saved, and in temporary declines in income a taxpayer might choose to provide for consumption by decreasing savings. Ergo, if taxation is regarded alongside “permanent income,” it should be less regressive (or more progressive) than if made comparable with annual income.

Sales taxes and excises (excepting those on luxuries) are generally regressive, because the spread of personal income consumed or spent on specific goods decreases as the level of personal income is raised. Poll taxes (also known as head taxes), calculated as a fixed amount per capita, obviously are regressive.

It is complicated to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to the uncertainty regarding 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 essentially on whether a national or a subnational (that is, provincial or state) tax is being decided.

In considering the economic effects of taxation, it is relevant to distinguish between various concepts of tax rates. The statutory rates will include those specified in legislature; generally speaking these are marginal rates, but occasionally they are mean rates. Marginal income tax rates signify the fraction of incremental income taken by taxation when income increases by one dollar. So, if tax burden increases by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax statutes usually contain graduated marginal rates—i.e., rates that rise as income rises. Heavy analysis of marginal tax rates must regard provisions apart from the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lowers by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points greater than specified in the statutory rates. Since marginal rates display how after-tax income is changed 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 understand the marginal effective tax rate applicable to income from business and capital, as it may be reliant on such considerations as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem determines that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates signify the portion of total income that is required in taxation. The pattern of average rates is the one that is relevant for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates usually rise with income, both because personal allowances are allowed for the taxpayer and dependents and because marginal tax rates are graduated; on the other side of things, preferential treatment of income received mostly by high-income households may dampen these effects, producing regressivity, as shown by average tax rates that decrease as income rises.

The Development of Data Projectors

The LCDs put for projection systems are typically small reflective or transmissive panels illuminated by a powerful arc lamp source. A number of lenses expands the reflected or transmitted image and sends it on the screen. For front-projection systems the LCD is located on the side of the screen as the viewer, although in rear-projection systems the screen is set off from behind. Projectors of greater expense and performance can have three distinct LCD panels, creating separate red, green, and blue images that blend to make a coloured picture on the screen.

The increasing demand for video presentations has put a growth in emphasis on the switching speed of liquid crystals. This has necessitated the creation of items build with smectic liquid crystals, some kinds of which possess a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most progressive smectic device. Inside it the liquid crystal molecules are arranged in layers that are perpendicular to the substrate planes, which are differentiated by one or two micrometres, and inside the layers the molecules are slanted, as illustrated in the figure. The host liquid crystal holds optically active molecules, and a scarcely perceptible consequence of the optical activity and the angle of the molecules is the presence 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 through the plane of the layers. Thus, there must be a permanent charge separation through the liquid crystal layer in the SSFLC, and its sign is directly partnered 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 hence reverse the tilt direction of the molecules. The respective change in optical properties can cause a change from light to dark when one or more polarizers are employed.

SSFLC devices have been marketed for larger passive-matrix presentations, but their high cost and intricacy has stopped them from creating any remarkable movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some promise for use as elements in projection systems or as viewfinders in digital cameras. Their speedy reacting allows them to be made use of in time-sequential colour systems, in which expensive colour filters are emulated by a coloured backlight that flashes red, green, and blue in rapid pulsing (about 100 cycles per second). For example, the liquid crystal can be switched to a transmissive state during the red and green periods then to a nontransmissive state during the blue period, having the upshot 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 objects, the chair could be the most important. While many other forms (save for the bed) are meant to support objects, the chair supports our human form. The term chair can be regarded here in the widest sense, from stool to throne to further pieces like the bench and sofa, which may be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously distinguished.

The social history of the chair is as interesting as its history as a creative art. The chair is not just a physical support or aesthetic piece; it was also an indicator of social rank. From the past royal courts there were significant signifiers between being seated on a chair with arms, on a chair with a back but without arms, or having to sit on a stool. In the recent century, a director’s and manager’s chair has been seen as iconic of superior rank, and even in democratic governments the speaker sits on a raised floor.

As its furniture purpose, the chair is utilised for a wealth of various forms. There are chairs structured to match man’s age and physical abilities (the high chair, the wheelchair) and to denote his rank in society (the executive chair, the throne). From the past 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, and four legs, chairs with or without arms, and chairs with or without backs. We have chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Contemporary lifestyle has demanded special chairs for use in automobiles and aircraft. Every one of these chair shapes have perfected to conform to different human desires. Due to its close link with man, the chair comes to its full importance only when used. Whereas it is irrelevant to one’s appreciation of a cupboard or a set of drawers if there is anything inside or not, a chair is really seen and regarded best with a person using it, because chair and sitter need the other. Thus the different limbs of the chair have been given labels likened to the parts of our human shape: arms, legs, feet, back, and seat.

Because the primary role of the chair is to support a body, its worth is evaluated principally from how fully it measures up to this practical job. Within the build of a chair, the carpenter is limited with particular static law and principal measurements. Inside these regulations, however, the chair creator has marvellous freedom.

The history of the chair extends over a period of several thousand years. There were societies that made unique chair forms, as expressive of the leading craft in the arenas of craft and aesthetics. From those cultures, a note needs to be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the result of expert design, were known from tomb findings. The first of these two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair had four legs crafted like those of a particular animal, a curved seat, leading to a sloping back supported with vertical stretchers. In this design a solid triangular design was created. There was in our view no significant variation in the creation of Egyptian thrones and chairs for regular people. The simple difference existed in the complexity of ornamentation, in the particulars of expensive inlays. The Egyptian folding stool in all likelihood was manufactured as an easily carried seat for soldiers. As a camp stool this form persisted for much later periods of time. But the stool then took on the role of a ceremonial seat, its original role as a folding stool ignored or forgotten. This can from today be noted, from as early as 1366–57 BC in two stools, crafted in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They are in the structure of folding stools but are not able to be folded because the seats are worked with wood. The easy build of the folding stool, being of two frames that cycle on metal bolts and have a seat of leather or fabric fastened between them, appeared again but some time later during the Bronze Age folding chairs of Scandinavia and northern Germany. The better recognised of those is the folding stool, made from ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is found not with any ancient fossil still existing but from a large amount of pictorial evidence. The best recognised is the klismos seen on the Hegeso Stele at the Dipylon burial ground in outer Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, only two of those are displayed. These strange legs were most likely to have been manufactured in bent wood and were in that case subjected to a large amount of pressure under the weight of the sitter. The joints joining the legs to the frame of the seat had to be therefore extremely strong and were overtly signified.

The Romans embued the Greek designs; quite a few casts of seated Romans offer evidence of a more heavyset and which appear to be a kind of less intricately built klismos. Both types, the light and heavy, were seen again during the Classicist period. The klismos influence is used in French Empire chairs, in English Regency, and in some kinds of marked uniqueness around Denmark and Sweden circa 1800.

China
The history of the chair in China can not be tracked as far back as in Egypt and Greece. From the Tang dynasty (AD 618–907) an unscathed collection of sketches and artworks had been preserved, detailing the insides and outer parts of Chinese households and the kinds of furniture. Kept also since the 16th century are some chairs constructed from wood or lacquered wood, that bear an astonishing familiarity to styles of previous chairs.

Just as in Egypt, there were two major chair forms in China: a chair having four legs and a folding stool. This four-legged chair was seen both with or without arms however always with its square seat and straight stiles (straight side supports) to firm the back. In one kind, it has been found, the stiles were slightly curved by the arms for the purpose of conform correctly to the structure of the S-shaped back splat (the basic upright of a chairback). The three sections are mortised onto the yoke-like top rail. Despite that the style of a back splat then had a foundation for English chairs from the Queen Anne period, wooden members that merely to a limited ability support corner joints (and furthermore are loose into the bargain) signify a design exclusive to Chinese chairs. The four legs pass through the seat frame, which stops about the rounded staves. All members are round in section or has rounded edges—referable as may be to the bamboo tradition. The seat is not pleasant and may have a plaited bottom. 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 way of collapsing. In patriarchal Chinese homes of this era armchairs likely were kept only for the senior people, for they were respected greatly.

The Chinese folding stool is believed to have been brought to China from the West. It is akin very much from the Egyptian or Scandinavian folding stools, but it has a change in that the top rail is elegantly joined to the two legs of the stool by means of a curved member, which is more often than not provided with metal mounts. From a Western point of view the resultant effect of both of these furniture designs is stylized. The structure and decorative issues are combined in a manner that is all at once both naïve and refined. The patchwork appearance is an outcome of the way that the individual members do not look to have been fixed by either glue or screws, but are mortised with one another and locked into position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also put its signature on the chair. Works of art display a type of chair with a relatively unrefined wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in the layers, stitched to bring out a pattern of small pads. The front board and a corresponding board in the back could be folded after loosening some small iron hooks. In this way the chair was a portable piece of furniture for traveling which, at the same time, gave the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is evidenced in engravings of interiors of rich Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this style of chair might also be found in countries in which Dutch styles of interior decoration and Dutch furniture won preference, it is not certain that the form actually was instigated in The Netherlands. Normally, the legs of the chair were smooth, round in section, and of thin shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was manufactured in vast numbers, as evidenced from one of Abraham Bosse’s engravings, in which there is a whole row of this kind of chairs lined up along a wall. The form asserts itself by its shapely proportions and delicate upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of styles—that was, to say, as progressed in Paris around 1750—conquered most of Europe and was imitated or copied into the mid-20th century. The chair owes this popularity to a combination of leisure and elegance. The seat suits to the human body and allows a relaxed seated position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are small upholstered pads over the armrests. Smooth transitions achieved between seat frame, legs, and back disguise all the joints, which are stable, constructed on craftsmanlike methodology even with the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are constructed from wood of fairly thick density; but each member is deeply molded, all extraneous wood has been removed, and more expensive chairs might be further embellished with intricately delicate and decorative engraving. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry is often used for all the upholstery on the seat, back, and armrests; canework is occasionally used instead of upholstery.

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

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

Essentially, bookkeeping grants two types of information: (1) the current value, or equity, of an entity and (2) any changes in value—profit or loss—taking placement in the enterprise over a particular time.

Management officials, investors, and credit grantors all demand this information: management so as to assess the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to interpret 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 grant a loan.

Bits and pieces of financial and numerical recordkeeping have been uncovered for nearly every nation with a commercial background. Records of business contracts have been uncovered in the archaelogical digs of Babylon, and accounts for both farms and estates have been held in ancient Greece and Rome. The two-entry way of bookkeeping began with the development of the enterprising republics of Italy, and tutorial books for bookkeeping were developed during the 15th century in various Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made factual financial records a requirement. The ancestry of bookkeeping, in fact, resembles the ancestry of commerce, industry, and government and, partially, helped in shaping it. The global movement of industrial and commercial activity demanded better professional decision-making methodology, which itself needed better sophistication in the selection, classification, and presentation of information, even more so with the aid of computers. Taxation and government regulation became more detailed and resulted in greater demand 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 become larger, and the demand for bookkeeping for their own operations went up.

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

Each month, generally, an income statement and a balance sheet are made from the trial balance posted from the ledger. The point of the income statement or profit-and-loss statement is to give an analysis of those changes that have taken place in the entity equity resulting due to the transactions of the period. The balance sheet displays the financial position of the corporation at any particular date regarding assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

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

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

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

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

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

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

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

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

Today the wheel has turned full circle. In the past 10 to 20 years there has been a powerful 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.
