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

The most common question asked when purchasing a new projector for the home, office, or classroom is: will I buy an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, short for ‘digital light processing’ are the two most popular projector imaging technologies. With so many company brands and different models available, it can be confusing for clients to decide between the two technologies. The fact is that LCD projectors give superior image quality and colour accuracy. The next paragraph will tell you why DLP projectors struggle with projecting the same grade of image quality.

Visualise a set of blinds in your household for your bedroom window. By twisting a rod you can have the shutters open or closed, depending on if you want to let light in or not. This is exactly how an LCD projector functions. Each pixel functions like an individual shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as experts like to call them. Each pixel element operates to either reflect light or block it.

How the light source is processed from the time the projector is turned on to when the image reaches your screen is extremely significant for image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by separating it into red, blue and green components, by three mirrors which project the coloured light to 3 individual LCD panels. The 3 LCD panels form the elements of the image by turning each pixel on and off. The pixels are then combined in a glass prism to send the projector image. A point to remember about LCD projectors is that all three colours are sent onto your wall all at once. The way a DLP projector operates is very different and even how an image comes out is not the same. With DLP, white light from the lamp is processed through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of projecting an image requires a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to produce the image elements. The elements of the image are cast 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 single total image. Using LCD projectors, all colours are available all the time to create the best brightness and great colour accuracy. In DLP, only one colour is available at once, and so resulting in lower colour brightness and accuracy. Some DLP designers have added a white segment into the colour wheel to improve all over brightness, but this further degrades colour accuracy.

I read in forums all the time that DLP gives a higher contrast ratio and therefore must be better. For those unsure, 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 projector is able to produce. DLP projectors do have high contrast specifications as compared to most LCD projectors. At one glance, this appears to be a benefit, however, in real life, the true black level is determined by the ambient light in the room where the projector is being used. Do not be duped by contrast specifications on websites and in brochures.

When the content you are trying to bring to life requires moving images, DLP projection technology can also create image errors, or ‘artifacts’. The most typical artifact that a DLP projector creates 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 pulled up. LCD projectors do not have this characteristic because all the colours are projected at once. DLP manufacturers have formed 3DLP solutions using 3 chips to solve the colour break up artifacts, but the price of these projectors make them almost impossible for many businesses and consumers.

Another variance between LCD and DLP is how they match the balance for the refractive qualities of light. Think back to high school science, and recall how the various colours of light refract varied amounts when directed through the same lens. The disadvantage with DLP projectors is that they take the one same panel with the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light in a different way. Usually with a DLP projector, an extra yellow colour will show above and some blue will be projected below an image containing something as simple as a lone black line. In manufacturing LCD projectors can be fixed to take away these effects on the projected image, as each colour is directed on isolated LCD panels.

The sole veritable plus (excluding price) with buying a DLP projector is its smaller total size and weight. However, this is only relevant for transport and cannot be traded off against the image benefits of LCD projectors. If the result of the picture quality is vital to you, then the answer is a no-brainer. Take an LCD projector! LCD projectors will definitely make bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

As the Dutch found preeminence in sea power during the 17th century, the initial yacht had been a pleasure craft used mostly by royalty and secondly by the burghers for the canals and the protected and unprotected waters of the Low Countries. Racing was incidental, arising as private games. English yachting started with King Charles II of England during his exile in the Low Countries. On his restoration to the English throne in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he called Mary. Charles and his brother James, the duke of York (James II, sovereign 1685–88), made additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 punt. Yachting became fashionable among the rich and royalty, but after that time the fashion did not last.

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

Yacht racing was seen in some organized fashion on the Thames around the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV ascended to sovereignty in 1820, it was 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 initiated at Cowes on the Isle of Wight in 1815, and royal patronage made the Solent – the strait between the mainland and the Isle of Wight – the perpetual setting of British yacht racing. The society at Cowes became the Royal Yachting Club, again at the rise of George IV. Every member was required to own boats of at least 20 tons (20,321 kg). Sailing matches for high stakes were held, and the society life was superlative. Ultimately Royal Yachting Club boats grew in size to over 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and persisted when the English held power. Sailing was largely for leisure and found its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and established a standard of luxury and sophistication for the later yachts in those waters from the late 19th century. The first enduring American yacht association, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens began the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts were within the design of such naval craft as brigantines, schooners, and cutters from the 17th century through the latter half of the 19th century. The style of large yachts was originally heavily put upon by the victory of America, which was designed by George Steers for a group led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its success at Cowes in 1851. The first yachts were not designed and manufactured in today’s sense, with merely a model used. Not until the latter 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 such study had done earlier for hulls.

Because almost all sailboats had been individually built, there arose a requirement for handicapping boats previous to the one-design class boats were built. Therefore, a rating rule was created, which ended up in the International Rule, adopted in 1906 and edited in 1919. Today, one of the most rapidly blossoming areas in sailing is that of one-design class boats. All boats in a one-design class are built to single requirements in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing between those boats can be held on an even par with no handicapping necessary. A prime example is the standard International America’s Cup Class taken on for racers in the 1992 America’s Cup race.

So long as yachting belonged primarily for the aristocracy and the affluent, money was no object, and the size of boats developed, in both length and weight. The ascendancy and preference of smaller boats occurred in the second 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 journey around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the hardiness of less sizeable craft. Thereafter in the 20th century, notably after World War II, smaller racing and pleasure craft became more common, down to the dinghy, a favoured training boat, of 3.7 m. In the late 20th century, boats of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, in which steam started to take the place of sail power in commercial boats, the steam engine, and later the internal-combustion engine, were increasingly employed in pleasure boats. Large power yachts were furthered to a high standard, and long-distance sailing became a favoured pastime of the well off. The earliest power yachts were paddle-wheel boats; these then gave way to those powered by the wholly submerged screw or propeller type of propulsion. Like naval and merchant craft, auxiliaries carrying both sail and power were the yacht archetype for many years. By the second half of the 20th century, several yachts were still auxiliaries, but the larger part were solely power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a boom in the manufacture of large steam yachts. In particular of these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was operated by a crew of more than 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 in World War II.

As bigger and better quality internal-combustion engines were produced, many large yachts began using them for power. The development of the diesel engine, employing heavy oil for fuel, was furthered for World War I. From the decade following that, big power-yacht building flourished, reaching a climax in the Orion (1930) at 3,097 tons. In that time the biggest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of large power boats lessened from 1932, and the trend after that was for smaller, less expensive boats. Following World War II, a lot of small naval vessels were sold to private owners for conversion to yachts. In the late 20th century, yachting has become a internationally popular activity enjoyed by thousands of yachtsmen personally sailing and keeping their own small recreational yachts. The amount of craft and sailors has increased steadily, not only in the traditional areas by the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are categorized by the impact they have on the placement of income and wealth. A proportional tax is one that applies the same relative liability on each taxpayer—i.e., where tax liability and income increase in equal proportion. A progressive tax is recognisable by a greater than proportional increase in the tax liability in relation to the growth in income, and a regressive tax is recognisable by a less than proportional rise in the comparative liability. Thus, progressive taxes are thought of as fighting inequalities in income distribution, whereas 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 categorically progressive, however, can become less so in the upper-income categories—especially if a taxpayer is allowed to lessen his tax base by declaring deductions or by leaving out some particular income aspects from his taxable income. Proportional tax rates which are applied to lower-income categories will also be more progressive if such personal exemptions are declared.

Income measured over a given year may not definitely give the most suitable measure of taxpaying requirements. For example, transitory rises in income could be saved, and within temporary declines in income a taxpayer could decide to provide for consumption by reducing savings. Therefore, if taxation is made comparable with “permanent income,” it will be less regressive (or more progressive) than when compared with annual income.

Sales taxes and excises (excepting those on luxuries) are mostly regressive, because the dissemination of individual income consumed or spent on a specific good lessens as the amount of personal income grows. Poll taxes (also called head taxes), nominated as a standard amount per capita, patently are regressive.

It is hard to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of uncertainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden is dependant fundamentally on whether a national or a subnational (that is, provincial or state) tax is being considered.

In regarding the economic purpose of taxation, it is essential to distinguish between differing ideas of tax rates. The statutory rates are those specified in legislature; often these are marginal rates, but occasionally they are average rates. Marginal income tax rates indicate the fraction of incremental income demanded by taxation when income rises by one dollar. Thus, if tax burden increases by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax laws commonly contain graduated marginal rates—i.e., rates that rise as income rises. Structured analysis of marginal tax rates should regard 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 growth in income, the marginal rate is 20 percentage points higher than nominated in the statutory rates. Since marginal rates signify how after-tax income increases or decreases in response to changes in before-tax income, they are the important ones for considering incentive effects of taxation. It is even more difficult to understand the marginal effective tax rate applied to income from business and capital, since it may be dependant on such factors as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem grants that the marginal effective tax rate in income from capital is nothing under a consumption-based tax.

Average income tax rates display the percentage of total income that is taken in taxation. The pattern of average rates is the one that is necessary for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates commonly 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 fundamentally by high-income households can dampen these effects, producing regressivity, as indicated by average tax rates that decline as income grows.

The Development of Data Projectors

The LCDs built in projection systems are typically small reflective or transmissive panels set off by a forceful arc lamp source. A line of lenses expands the reflected or transmitted image and sends it onto a screen. With front-projection systems the LCD is set on the same side of the screen as the viewer, however in rear-projection systems the screen is lit from behind. Projectors of higher expense and capability sometimes have three separated LCD panels, creating separate red, green, and blue images that mesh to make a coloured image on the screen.

The growing demand for film presentations has granted a growth in emphasis on the switching speed of liquid crystals. This has demanded the development of objects using smectic liquid crystals, certain types of which emit a better 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 set out in perpendicular layers to the substrate planes, which are distanced by one or two micrometres, and inside the layers the molecules are on a slant, as demonstrated in the figure. The host liquid crystal holds optically active molecules, and a slight consequence of the optical activity and the shape 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 across the liquid crystal layer in the SSFLC, and its sign is directly attracted to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The resultant change in optical properties can create a change from light to dark if one or more polarizers are employed.

SSFLC devices have been publicized for big passive-matrix presentations, but their expensiveness and detail has impeded them from creating any particular impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some probability for use as parts in projection systems or as viewfinders in digital cameras. Their quick responding allows them to be used in time-sequential colour systems, in which costly colour filters are emulated with a coloured backlight that flashes red, green, and blue in rapid pulsing (approx 100 cycles a second). For example, the liquid crystal may be switched to a transmissive state for the red and green periods but then to a nontransmissive state in the blue period, with the upshot that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Of all furniture needs, the chair could be paramount. While most of the other pieces (apart from the bed) are meant to support objects, the chair supports our human form. The term chair is regarded here in the widest sense, from stool to throne to further forms like a bench or 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 clearly defined.

The social history of the chair is as exciting as its history as art and craft. The chair is not merely a physical support and aesthetic craft; it can also be semiotic of social status. At the old royal courts there were clear distinctions between possessing a chair with arms, or a chair with a back but without arms, or having to squat on a stool. During the last century, the director’s or manager’s chair has been regarded as iconic of superior position, like in democratic governments the speaker sits on a higher platform.

As a furniture form, the chair is utilised for a range of different makes. There are chairs manufactured to match man’s age and physical condition (the high chair, the wheelchair) and to indicate his position in society (the executive chair, the throne). During the past there were chairs used for birth (birth chairs); in the 20th century, there have been chairs used for ending life (the electric chair). We make chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Modern living has demanded special chairs for use in automobiles and aircraft. Every one of these chair types has been perfected to fit to different human desires. Due to its particular link with man, the chair comes to its full purpose only when being utilised. Although it doesn’t make any difference to one’s appreciation of a cupboard or a set of drawers whether there are items inside or not, a chair is understood and evaluated with a person sitting on it, for chair and sitter need the other. Thus the individual areas of a chair were named like the names of the human parts: arms, legs, feet, back, and seat.

Because the obvious job of a chair is to support the human body, its credit is judged basically from how suitably it does fulfill this practical job. In the design of a chair, the builder is limited in certain static laws and principal measurements. Through these limitations, however, the chair designer has extensive freedom.

The history of the chair lasted dates of several thousand years. There existed societies that held unique chair forms, as seen of the foremost craft in the spheres of handling and aesthetics. Out of such cultures, individual mention must be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the construct of masterful scheme, are today a finding from tombs. The first of them is a four-legged chair with a back, the other a folding stool. The original Egyptian chair had four legs formed similar to those of some animal, a curved seat, and a sloping back supported by vertical stretchers. In this design a stable triangular construction was obtained. There appeared to be no significant change between the structure of Egyptian thrones and chairs for regular populace. The simple change was in the kind of ornamentation, in the selection of more valuable inlays. The Egyptian folding stool most probably was crafted as an easily stored seat for army officers. As a camp stool that kind existed for much later times. But the stool also then was created as the task of a ceremonial seat, its technical history as a folding stool neglected or forgotten. This can now be found, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were constructed in the shape of folding stools but can’t be folded as the seats are made with wood. The plain structure of the folding stool, being of two frames that cycle on metal bolts and hold a seat of leather or fabric set between them, reappeared some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The better known of this type is the folding stool, made of ashwood, which can now be seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is found not from any ancient object still extant but found in a large amount of pictorial items. The better known is the klismos drawn on the Hegeso Stele at the Dipylon burial location outside Athens (c. 410 BC). This is a chair with a backward-sloping, curved backboard and four curving legs, only two of those legs are visible. These unique legs were likely to be crafted of bent wood and were likely to have been subjected to huge pressure under the weight of the sitter. The joints attaching the legs to the frame of the seat were therefore extremely strong and were visibly indicated.

The Romans emulated the Greek designs; evidence of statues of seated Romans offer designs of a thicker and which appear to be a rather less intricately built klismos. Both styles, the light and heavy, were seen again during the Classicist epoch. The klismos chair can be seen in French Empire furniture, in English Regency, and in some kinds of profound originality within Denmark and Sweden during 1800.

China
The ancestry of the chair in China isn’t able to be charted as well as the ancestry of the chair in Egypt and Greece. From the Tang dynasty (AD 618–907) an unscathed folio of images and paintings has been kept safe, detailing the insides and outside of Chinese homes and the kinds of furniture. Kept also of the 16th century are a number of chairs crafted from wood or lacquered wood, that hold an intriguing likeness to designs of past chairs.

Just like in Egypt, there existed two iconic chair designs in China: a chair having four legs and a folding stool. The four-legged chair has been constructed both with and without arms although always having its square seat and straight stiles (standing side supports) to give support to the back. In one image, though, the stiles could be slightly curved on top of the arms for the purpose of conform to the form of the S-shaped back splat (the centre upright of the back). The three sections had been mortised into the yoke-like top rail. Although the design of a back splat had an inspiration for English chairs of the Queen Anne period, wooden items that could only to a restricted ability support corner joints (and furthermore are loose as well) are a feature signatory to Chinese chairs. The four legs sit through the seat frame, which stops around the rounded staves. Every member is round in section or is given rounded edges—an acknowledgement as may be to the bamboo tradition. The seat is unpleasant to sit in and may have had a plaited form. These chairs required of the sitter to remain stiff and upright; for when too much pressure is forced on the back, the chair has a tendency to collapse. In patriarchal Chinese households of this epoch armchairs likely were only for senior individuals, for they were greatly esteemed.

The Chinese folding stool is understood to have travelled to China from the West. It is akin very much from the Egyptian or Scandinavian folding stools, but it has a dissimilarity in that the top rail is prettily fixed to the two legs of the stool by using a curved member, which is often possessing metal mounts. From a Western point of view the ultimate effect of these two furniture items is stylized. The structure and decoration aspects are combined in a way that is simultaneously naïve and refined. The pieced-together appearance is an upshot of the manner that the individual members do not appear to have been adjoined by use of either glue or screws, but were mortised with one another and fixed in its place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also had its signature on the chair. Works of art show a kind of chair with a relatively brusque wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between, stitched to produce a pattern of small pads. The front board and a similar board at the back could be folded after unscrewing some tiny iron hooks. In this way the chair was an easily portable piece of furniture while traveling which, at the same period, had the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered style of chair is displayed in engravings of the interiors of rich Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this design of chair may also be seen in countries in which Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not believed that the form actually was born in The Netherlands. Generally, the legs of the chair were smooth, round in section, and of slim shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was crafted in considerable amounts, as can be seen from one of Abraham Bosse’s engravings, in which a whole row of these chairs lined up by a wall. The style asserts itself with its harmonious proportions and fine upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature style—that was, as developed in Paris around 1750—disseminated through most of Europe and has been imitated or copied during the mid-20th century. The chair owes such popularity to a combination of relaxation and delicacy. The seat conforms 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 small upholstered pads covering the armrests. Smooth transitions are achieved between seat frame, legs, and back cover all the joints, which are constructed on craftsmanlike methodology even with the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are made from wood of relatively thick dimensions; but all the members are deeply molded, all superfluous wood has been taken away, and more expensive designs may be further embellished with intricately delicate and decorative engravings. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry is used for all of the upholstery on the seat, back, and armrests; crosshatched cane is occasionally used instead of upholstery.

English chairs in the 18th century were more open in style than the French. The French taste for stylistic uniformity, which spread from the highest circles in Paris and Versailles over most of France and found favour 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 reknowned and was widely distributed throughout the world.

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

In cheaper products of inferior workmanship, bourgeois chairs of the 19th century carried on the traditions of the 17th and 18th centuries. The only real innovations were the bentwood (wood that has been bent and shaped) chairs in beech that became popular all over the world and were still made in the 20th century. Around 1900 the continental Art Nouveau and Jugendstil styles (French and German styles characterized by organic foliate forms, sinuous lines, and non-geometric forms), and the Arts and Crafts movement in England (established by the English poet and decorator William Morris to reintroduce idealized standards of medieval craftsmanship), gave rise to original chair designs by Eugène Gaillard in France, Henry van de Velde in Belgium, Josef Hoffman in Austria, Antonio Gaudí in Spain, and Charles Rennie Mackintosh in Scotland. These new furniture styles did not exercise wide, let alone decisive, influence. The Art Nouveau chairs designed by the French architect Hector Guimard, for example, are collector’s pieces, but his name is known to a broader public only because of his fanciful entrances to the Paris Métro.

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, purport that completely new chair forms will probably be evolved in the future.

What is Bookkeeping?

Bookkeeping is the recording of the money values of the operation of a business. Bookkeeping provides the figures from which accounts are prepared but is a distinct process, prerequisite to accounting.

Predominantly, bookkeeping finds two kinds of information: (1) the current value, or equity, of a business and (2) the change in value—profit or loss—taking placement in the business within a singular period of time.

Management officials, investors, and credit grantors all need this information: management so as to assess the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to understand the upshots of business operations and make decisions about buying, holding, and selling securities; and credit grantors so as to assess the financial statements of an enterprise in assessing whether to allow a loan.

Pieces of financial and numerical records can be seen for nearly every civilization with a commercial history. Records of trade contracts were discovered in the archaelogical digs of Babylon, and accounts for both farms and estates had been kept in ancient Greece and Rome. The double-entry manner of bookkeeping came with the development of the enterprising republics of Italy, and manuals for bookkeeping were developed in the 15th century in some Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made accurate financial books a paramount factor. The past of bookkeeping, in fact, reflects closely the history of commerce, industry, and government and, in some part, assisted to form it. The global market of industrial and commercial activity called for better sophisticate decision-making methodology, which in its turn required greater sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government regulation became more significant and resulted in increased requirement for information; firms had to show information to go with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also became sizeable, and the requirement for bookkeeping for their inner operations went up.

While bookkeeping methodology can be extremely multifaceted, all are based on two types of books employed in the bookkeeping procedure—journals and ledgers. A journal should have the daily transactions (sales, purchases, etcetera), and the ledger contains the information of individual accounts. The daily records kept in the journals are entered in the ledgers.

At the end of each month, by general practice, an income statement and a balance sheet are constructed from the trial balance posted within the ledger. The purpose of the income statement or profit-and-loss statement is to present an analysis of any changes that took place in the enterprise equity because of the events of the period. The balance sheet shows the financial situation of the enterprise at any particular date in terms of 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.
