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

The common question that is asked when acquiring a new projector for the home, office, or classroom is: should I purchase an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, an acronym for ‘digital light processing’ are the two most common projector imaging technologies. With so many company brands and different types available, it can be confusing for clients to make a choice between these technologies. It comes down to the fact that LCD projectors give superior image quality and colour accuracy. The article below will explain why DLP projectors struggle with bringing up the same rate of image quality.

Visualise a set of blinds in your home over your bedroom window. By twisting a rod you can have the shutters open or closed, according to whether you want to let light in or not. And such is exactly how an LCD projector works. Each pixel operates like a unique 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 professionals 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 is switched on to when the image reaches your screen is extremely important for image quality, brightness and colour accuracy. LCD projectors shine white light from the lamp by splitting it into red, blue and green components, by three mirrors which transfer the coloured light to 3 different LCD panels. The 3 LCD panels cast the elements of the image by turning each pixel on and off. The pixels are then projected in a glass prism to create the projector image. Something to remember about LCD projectors is that all three colours are delivered onto your projected surface at the same time. The way a DLP projector runs is totally different and even the final product of how an image appears 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 way of making 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 create the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s eyes will then put together each coloured element of the image into the total image. In LCD projectors, all colours are available all the time to deliver high brightness and great colour accuracy. In DLP, only one colour is available at any given time, and so causing lower colour brightness and accuracy. Some manufacturers have placed a white segment into the colour wheel to improve all over brightness, but this further damages colour accuracy.

I read in forums all the time that DLP offers 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 machine is capable of producing. DLP projectors do provide high contrast specifications when compared to a majority of LCD projectors. At first glance, this seems to be a plus, however, in the real world, the true black level is determined by the ambient light in the room where the projector is utilised. Do not be tricked by contrast specifications on websites and in brochures.

When the content you wish to view has moving images, DLP projection technology can also have image marks, or ‘artifacts’. The most common artifact that a DLP projector shows with moving images is colour break up. Colour break up is inherent in DLP systems because moving images keep changing between the time red, blue and green colours are displayed. LCD projectors do not have this disadvantage because the colours are sent at once. DLP manufacturers have developed 3DLP solutions using 3 chips to resolve the colour break up problem, but the price 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. Think back to high school science, and recall how different colours of light refract differing amounts when projected through the same lens. The disadvantage 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 differently. Often with a DLP projector, an extra yellow colour will come through above and an extra blue will be projected below an image of something as simple as a single black line. In manufacturing LCD projectors can be fixed to remove these effects on the projected image, because each colour is processed on isolated LCD panels.

The only actual buy point (excluding price) with choosing a DLP projector is its smaller overall size and weight. However, this is only relevant in regard to mobility and has to be traded off against the image plusses of LCD projectors. If the outcome of the picture quality is important to you, then the answer is easy. Go with an LCD projector! LCD projectors will consistently show bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch rose to dominance in sea power during the 17th century, the early yacht became a pleasure craft used mostly by royalty and later by the burghers on the canals as well as the protected and unprotected waters of the Low Countries. Racing was incidental, borne from private matches. English yachting started with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English royalty in 1660, the city of Amsterdam gave him a 20-metre (66-foot) leisure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, ruled 1685–88), ordered for more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 punt. Yachting was found to be fashionable among the rich and royalty, but after that period the habit did not last.

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

Yacht racing was seen in some ordered fashion 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 sovereignty in 1820, it came to be named 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 society had been initiated at Cowes on the Isle of Wight in 1815, and royal patronage made the Solent – the strait between the mainland and the Isle of Wight – the perpetual site of British racing. The society at Cowes became the Royal Yachting Club, again at the accession of George IV. Each member was required to own boats of at least 20 tons (20,321 kg). Sailing races for high bets were held, and the social life was superlative. Eventually Royal Yachting Club boats grew in size to bigger than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and continued when the English had control. Sailing was mostly for fun and rose to its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a standard of luxury and elegance for the later yachts in the area from the late 19th century. The first persisting American yacht club, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens began the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts 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 bigger yachts was initially largely put upon 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.) was named after its win at Cowes in 1851. Early yachts were not designed and built in today’s sense, with just a model used. Not until the later half of the 19th century did what was called naval architecture come into being. Not until the 1920s did the use of the science of aerodynamics do for the craft of sails and rigging what science had previously done for hulls.

Because most of all sailboats had to be individually built, there was a need for handicapping boats before the one-design class boats were made. Thus, a rating rule came into being, which ended up in the International Rule, taken on in 1906 and revised in 1919. In modern times, one of the fastest flourishing areas in sailing is that of one-design class boats. All boats in a one-design class are created to standard requirements in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing for such boats can be held on an even par with no handicapping required. A great example is the uniform International America’s Cup Class taken on for participants in the 1992 America’s Cup race.

So long as yachting was an activity mostly for the royal and the rich, cost was no problem, and the size of boats increased, in both length and weight. The promotion and desire of smaller craft came in the later 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) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the hardiness of small yachts. Following this in the 20th century, particularly after World War II, smaller racing and leisure yachts became more popular, 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, in which steam began to replace sail power in commercial boats, the steam engine, and later the internal-combustion engine, were used increasingly in pleasure boats. Large power yachts were progressed to a high element, and long-distance travel turned into a favourite pastime of the rich. The earliest power yachts were paddle-wheel boats; those then gave rise to those powered by the completely submerged screw or propeller kind of propulsion. As well as naval and merchant yachts, auxiliaries with both sail and power were the yacht archetype for many years. By the later half of the 20th century, many yachts were still auxiliaries, but the larger part were only power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a rise in the manufacture of more sizeable steam yachts. In particular within 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 at least 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 in World War II.

As larger and more reliable internal-combustion engines were created, many large boats were using them for power. The establishment of the diesel engine, using heavy oil for fuel, was furthered during World War I. In the decade that followed, bigger power-yacht building blossomed, hitting a climax in the Orion (1930) at 3,097 tons. During that point the best auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of large power boats lessened after 1932, and the fashion thereafter was in preference of smaller, less pricey craft. Following World War II, many small naval vessels were bought by private owners for conversion to yachts. At the late 20th century, yachting has become a globally popular competition enjoyed by thousands of yachtsmen individually sailing and keeping their own small pleasure yachts. The amount of yachts and owners increased steadily, not only in the traditional places along the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be distinguished by the impact they have on the placement of income and wealth. A proportional tax is one that imposes the same relative onus on all taxpayers—i.e., when tax liability and income grow in the same proportion. A progressive tax is characterized by a larger than proportional growth in the tax burden in relation to the rise in income, and a regressive tax is recognised by a less than proportional growth in the comparative burden. So, progressive taxes are viewed as fighting inequity in income distribution, while regressive taxes are seen to result in an increase these inequalities.

The taxes that are often believed to be progressive include individual income taxes and estate taxes. Income taxes that are initially progressive, however, could become less so within the upper-income demographic—especially if a taxpayer is able to reduce his tax base by declaring deductions or by leaving out certain income parts from his taxable income. Proportional tax rates when applied to lower-income categories will also be more progressive if exemptions of a personal nature are declared.

Income measured over the course of a given year does not definitely offer the most appropriate measure of taxpaying status. For example, transitory rises in income might be saved, and during temporary declines in income a taxpayer may decide to pay for consumption by taking from savings. So, if taxation is compared along with “permanent income,” it can be less regressive (or more progressive) than if held in comparison with annual income.

Sales taxes and excises (save on luxuries) are mostly regressive, because the portion of personal income consumed or spent for a specific good lessens as the amount of personal income increases. Poll taxes (aka head taxes), calculated as a fixed amount per capita, obviously are regressive.

It is difficult to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, due to the uncertainty around the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden depends essentially on whether a national or a subnational (that is, provincial or state) tax is being decided.

In assessing the economic purpose of taxation, it is important to differentiate between varied concepts of tax rates. The statutory rates are dictated in legislature; generally these are marginal rates, but sometimes they are mean rates. Marginal income tax rates indicate the fraction of incremental income that is demanded by taxation when income increases by one dollar. Ergo, if tax burden grows by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax legislature often contain graduated marginal rates—i.e., rates that grow as income rises. Heavy analysis of marginal tax rates must consider provisions other than 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 higher than indicated in the statutory rates. Since marginal rates signify how after-tax income moves in response to changes in before-tax income, they are the appropriate ones for regarding incentive effects of taxation. It is even more difficult to realise the marginal effective tax rate to apply to income from business and capital, because it may depend 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 nil under a consumption-based tax.

Average income tax rates display the part of total income that is paid 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 increases with income. Average income tax rates usually increase with income, both because personal allowances are allowed for the taxpayer and dependents and because marginal tax rates are graduated; on the flip side, preferential treatment of income received for the most part by high-income households could dampen these effects, forcing regressivity, as shown by average tax rates that decline as income rises.

The Development of Data Projectors

The LCDs put for projection systems are most often small reflective or transmissive panels set off by a powerful arc lamp source. A line of lenses expands the reflected or transmitted image then sends it on the screen. With front-projection systems the LCD is situated on the side of the screen as the viewer, however in rear-projection systems the screen is lit from behind. Projectors of greater expense and capacity might be found with three separate LCD panels, reflecting separate red, green, and blue images that come together to create a coloured image on the screen.

The increasing demand for visual presentations has granted a particular emphasis on the switching speed of liquid crystals. This has demanded the development of devices using smectic liquid crystals, particular types of which have a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most developed smectic device. Within it the liquid crystal molecules are arranged in layers perpendicular to the substrate planes, which are distanced by one or two micrometres, and in the layers the molecules are on a slant, as shown in the figure. The host liquid crystal has optically active molecules, and a slight consequence of the optical activity and the tilt of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, comparable 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. Thus, there exists a permanent charge separation throughout the liquid crystal layer in the SSFLC, and its sign is directly coupled to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and in so doing reverse the tilt direction of the molecules. The resultant change in optical properties can create a change from light to dark when one or more polarizers are utilised.

SSFLC devices have been marketed for large passive-matrix displays, but their expensiveness and complex nature has impeded them from enjoying any great progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some possibility for use as elements in projection systems or as viewfinders in digital cameras. Their quick response allows them to be employed in time-sequential colour systems, in which costly colour filters are taken out for a coloured backlight that flashes red, green, and blue in quick pulsing (approx 100 cycles per second). For example, the liquid crystal could be switched to a transmissive state between the red and green periods then to a nontransmissive state for the blue period, displaying the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From all the furniture items, the chair might be the most important. While most other pieces (save the bed) are devised to support objects, the chair supports your human form. The term chair can be viewed here in the common sense, from stool to throne to complex items such as the bench and sofa, which can be regarded as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently definitive.

The social history of the chair is as exciting as its history as art and craft. The chair is not simply a physical support or an aesthetic artwork; it historically was semiotic of social status. Within the old royal courts there were plain connotations between being led to a chair with arms, sitting on a chair with a back but without arms, and having to squat on a stool. In the recent century, the director’s or manager’s chair has risen a symbol of superior rank, and even in democratic parliaments the speaker sits on a high-set level.

In a furniture creation, the chair ranges from a wealth of different makes. There are chairs designed to fit man’s age and physical form (the high chair, the wheelchair) and to connotate his position in society (the executive chair, the throne). From historical times there were chairs used 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, and/or four legs, chairs with or without arms, and chairs with or without backs. We have chairs that can be folded up, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has developed unique chairs for automobiles and aircraft. Every one of these chair shapes has evolved to conform to growing human needs. From its unique importance with man, the chair appears to its full importance only when utilised. Although it is not relevant to one’s appreciation of a cupboard or a set of drawers if there is anything inside or not, a chair is understood best and judged best with a person utilising it, for chair and sitter require each other. Thus the individual elements of a chair were given names likened to the parts of our human shape: arms, legs, feet, back, and seat.

Because the clear job of the chair is to support a human body, its credit is evaluated firstly for how fully it measures up to this practical function. Within the structure of the chair, the maker is limited for some static regulation and principal measurements. In these boundaries, however, the chair designer has awesome freedom.

The history of the chair is an era of several thousand years. There were peoples that made significant chair forms, expressive of the leading work in the arenas of skill and design. In these cultures, particular mention should be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of careful design, are now found from tombs. The first of these is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair had four legs structured similar to those of a designated animal, a curved seat, and with a sloping back supported over vertical stretchers. From this a strong triangular construction was crafted. There was apparently no particular variation in the creation of Egyptian thrones and chairs for common peasantry. The real difference lied in the complex ornamentation, in the choice of more expensive inlays. The Egyptian folding stool probably was created for an easily portable seat for army. As a camp stool this form existed for much later days. But the stool also then was created for the use of a ceremonial seat, its technical job as a folding stool neglected or forgotten. This can already be seen, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were constructed in the construction of folding stools but are not able to be folded as the seats were created from wood. The simple structure of the folding stool, consisting of two frames that rotate on metal bolts and hold a seat of leather or fabric set between them, can be seen somewhat later during the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognised of this form is the folding stool, crafted from ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is known not from any ancient fossil still in form but as in a variety of pictorial material. The better recognised is the klismos depicted on the Hegeso Stele at the Dipylon burial location just out of Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, only two of these legs can be shown. These curved legs were most likely to be created in bent wood and were likely to have been put under huge pressure under the weight of the sitter. The joints attaching the legs to the frame of the seat had to be therefore extremely strong and were visibly indicated.

The Romans adopted the Greek chair; quite a few casts of seated Romans are chairs of a thicker and apparently slightly less delicately crafted klismos. Both designs, the light and the heavy, were revived during the Classicist epoch. The klismos style is evidenced in French Empire styles, in English Regency, and in some kinds of marked individuality within Denmark and Sweden from 1800.

China
The ancestry of the chair in China isn’t able to be charted as far back as the ancestry of the chair in Egypt and Greece. From the Tang dynasty (AD 618–907) an undamaged folio of sketches and works of art had been preserved, displaying the interiors and exterior of Chinese houses and their furniture. Kept also of the 16th century are a number of chairs crafted of wood or lacquered wood, that possess an amazing likeness to images of ancient chairs.

As was the case in Egypt, there were two iconic chair forms in China: a chair having four legs and a folding stool. This four-legged chair was found both with and without arms though never without a square seat and straight stiles (vertical side supports) to give support to the back. In one form, it has been found, the stiles were lightly curved above the arms in order to sit right with the shape of the S-shaped back splat (the main upright of its back). All three areas are mortised in the yoke-like top rail. While the style of the Chinese back splat later had an inspiration for English chairs during the Queen Anne period, wooden pieces that merely to a limited ability support corner joints (and then were loose as well) indicate a design signatory to Chinese chairs. The four legs pass through the seat frame, which finishes upon the rounded staves. All the members are round in section or has rounded edges—references perchance to the bamboo tradition. The seat is not comfortable and occasionally had a plaited seat. These chairs required the sitter to hold themselves stiff and upright; if too much weight is forced on the back, the chair has a way of collapsing. In patriarchal Chinese homes of this period armchairs presumably were kept for elderly individuals, for they were respected greatly.

The Chinese folding stool is understood to have travelled to China from the West. It is akin much from the Egyptian and Scandinavian folding stools, but it has a change in that the top rail is delicately affixed to the two legs of the stool with a curved member, which is generally possessing metal mounts. From a Western understanding the ultimate effect of both furniture items is stylized. The constructive and decorative aspects are combined in a manner that is all at once naïve and refined. The patched up appearance is an outcome of the fact that the individual items do not appear to have been fixed together with either glue or screws, but were mortised into one another and fixed in place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also had its name on the chair. Artworks display a design of chair with a relatively unrefined wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing between, stitched to produce a pattern of small pads. The front board and a corresponding board from the back could be folded after loosening some small iron hooks. In this way the chair was an easily portable piece of furniture for traveling which, in the same time, gave the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair can be evidenced in engravings of the interior of affluent Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this style of chair is also seen in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not determined that the innovation actually originated in The Netherlands. Typically, the legs of the chair will be smooth, round in section, and of slender dimensions; they are occasionally baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was made in large quantities, as can be surmised from one of Abraham Bosse’s engravings, in which there is an entire row of such chairs lined up by a wall. The form asserts itself with its shapely proportions and delicate upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of styles—that is, as created in Paris around 1750—conquered most of Europe and has been imitated or copied into the mid-20th century. The model owes its popularity to a combination of relaxation and charm. The seat adheres to the human body and grants a relaxed sitting position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are little upholstered pads covering the armrests. Smooth transitions made between seat frame, legs, and back conceal all the joints, which are constructed on craftsmanlike practices despite the absence of stretchers between the legs.

French Rococo chairs and imitations of them have wood of relatively thick measurements; but each member is deeply molded, all extraneous wood has been removed, and more upmarket items may be further embellished with intricately delicate and decorative engravings. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for all of the upholstery on the seat, back, and armrests; canework is in some cases used rather than upholstery.

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

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

Basically, bookkeeping provides two parts of information: (1) the current value, or equity, of the business and (2) any changes in value—profit or loss—taking position in the enterprise over a singular time.

Management officials, investors, and credit grantors all demand such information: management so as to understand the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to interpret the results of business operations and make decisions for buying, holding, and selling securities; and credit grantors so as to regard the financial statements of an entity in deciding whether to give a loan.

Evidence of financial and numerical record charts have been uncovered for just about every society with a commercial background. Records of trade contracts were uncovered in the archaelogy of Babylon, and accounts for both farms and estates were held in ancient Greece and Rome. The double-entry method of bookkeeping began with the furthering of the entrepeneurial republics of Italy, and tutorial books for bookkeeping were created during the 15th century in many Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made accurate financial recordkeeping a must-have. The ancestry of bookkeeping, in fact, closely resembles the history of commerce, industry, and government and, in part, assisted forming it. The global movement of industrial and commercial activity required greater cosmopolitan decision-making methodology, which in its turn called for better sophistication in the selection, classification, and presentation of information, more so with the aid of computers. Taxation and government regulation became more detailed and resulted in greater demand for information; business entities 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 became sizeable, and the need for bookkeeping for departmental operations increased.

Though bookkeeping procedures can be very complex, all of it is based on two types of books utilised in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, etcetera), and the ledger contains the details of individual accounts. The daily records kept in the journals are put in the ledgers.

At the end of every month, generally speaking, an income statement and a balance sheet are created 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 those changes that took place in the enterprise equity from the events of the period. The balance sheet displays the financial condition of the company at a particular point in time 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 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.
