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

The most typical question heard when looking for a new projector for the home, office, or classroom is: do I purchase an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two most popular projector imaging technologies. With so many company brands and models available, it can be overwhelming for consumers to choose between these technologies. Ultimately LCD projectors offer superior image quality and colour accuracy. The article below explains why DLP projectors struggle with bringing up a comparable rate of image quality.

Think of a set of blinds in your house for your bedroom window. With the twist of a rod you can have the shutters open or closed, according to if you want to let light in or not. This is exactly how an LCD projector operates. Each pixel functions like an individual shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as the pros like to call them. Each pixel element operates to either reflect light or block it.

How the light source is processed from the point when the projector switches on to when the image reaches your screen is ultimately important with regard to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by splitting it into red, blue and green components, by three mirrors which direct the coloured light to 3 different LCD panels. The 3 LCD panels form the elements of the image by processing each pixel on and off. The pixels are then meshed in a glass prism to deliver the projector image. Something to realise about LCD projectors is that all three colours are directed onto your wall at once. The way a DLP projector works is totally 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 creating an image casts 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 projected in sequence on the screen, one colour at a time. The viewer’s vision will then put together each coloured element of the image into the total image. With LCD projectors, all colours are available all the time to form the top level of brightness and superb colour accuracy. In DLP, only one colour is available at once, causing lower colour brightness and accuracy. Some DLP manufacturers have put a white segment for the colour wheel to improve brightness overall, but this further lessens colour accuracy.

I find in forums all the time that DLP gives a higher contrast ratio and thus must be superior. For those who are 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 projector is capable of. DLP projectors do provide high contrast specifications when compared to the majority of LCD projectors. At first glance, this appears to be a plus, however, in real life, the true black level is determined by the ambient light in the room where the projector is in use. Do not be fooled by contrast specifications on websites and in brochures.

When the content you are trying to view needs moving images, DLP projection technology also creates image marks, or ‘artifacts’. The most common artifact that a DLP projector shows with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images change up between the time red, blue and green colours are displayed. LCD projectors do not have this characteristic because every colour is processed simultaneously. DLP developers have formed 3DLP solutions using 3 chips to answer the colour break up problem, but the expense of these projectors make them hardly practical for many businesses and consumers.

Another variance between LCD and DLP is how they make up for the refractive qualities of light. Remember back to high school science, and remember how the different colours of light refract different amounts when projected through the same lens. The disadvantage with DLP projectors is that they take the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light at different levels. Generally with a DLP projector, some extra yellow colour will be projected above and an extra blue will be projected below an image containing something as simple as a straight black line. During manufacturing LCD projectors can be adapted to minimize these effects on the projected image, as each colour is projected on a separate LCD panels.

The one veritable plus (excluding price) with choosing a DLP projector is its smaller overall size and weight. However, this is only relevant with regard to mobility and cannot be traded off against the image benefits of LCD projectors. If resulting picture quality is vital to you, then the solution is a no-brainer. Choose an LCD projector! LCD projectors will constantly show bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

As the Dutch found preeminence in sea power during the 17th century, the first yacht became a pleasure craft used mostly by royalty and secondly by the burghers in the canals and the protected and unprotected waters of the Low Countries. Yacht racing was incidental, arising as private matches. English yachting began with King Charles II of England during his exile in the Low Countries. On his return to the English monarchy in 1660, the city of Amsterdam gave him a 20-metre (66-foot) pleasure 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, sovereign 1685–88), ordered for more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 punt. Yachting rose as fashionable with the affluent and nobility, but after that time the trend did not last.

The first yacht group in the British Isles, the Water Club, was instigated around about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, and held great naval panoply and rigour. The closest thing to a race was the “chase,” when the “fleet” pursued an imaginary enemy. The club went on, mostly as a social club, until 1765, and in 1828, after conglomerating with other organisations, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some ordered method on the Thames around the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV rose to the throne in 1820, it came to be known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht society had been formed at Cowes on the Isle of Wight in 1815, and royal funding made the Solent – the strait between the mainland and the Isle of Wight – the continued setting of British yacht racing. The club at Cowes became the Royal Yachting Club, likewise at the ascension of George IV. Each member was required to have boats of at least 20 tons (20,321 kg). Sailing matches for large stakes were held, and the club life was wonderful. Ultimately Royal Yachting Club boats grew in size to bigger than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and persisted when the English gained power. Sailing was mostly for leisure and found its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and set a standard of luxury and sophistication for the later yachts in that area from the late 19th century. The first enduring American yacht organisation, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens instigated the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts followed the design of such naval craft as brigantines, schooners, and cutters from the 17th century through to the second half of the 19th century. The style of large yachts was first heavily affected 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 victory at Cowes in 1851. Earlier yachts were not designed and built in the modern sense, with only a model used. Not until the second half of the 19th century did what was labeled naval architecture come into action. Not until the 1920s did the application of the science of aerodynamics do for the design of sails and rigging what science had previously done for hulls.

Because nearly all sailboats were individually built, there came a desire for handicapping boats as this was before the one-design class boats were built. Thus, a rating rule was decreed, which is found in the International Rule, adopted in 1906 and amended in 1919. Today, one of the fastest blossoming areas in the field of sailing is that of one-design class boats. All boats in a one-design class are created 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 done on an even playing field with no handicapping required. A great example is the uniform International America’s Cup Class adopted for racers in the 1992 America’s Cup race.

As long as yachting was done largely for the nobility and the wealthy, cost was no object, and the size of boats increased, in both length and weight. The ascendancy and desire of smaller yachts occurred in the latter half of the 19th century out of the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A journey around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of less sizeable yachts. Later in the 20th century, particularly after World War II, smaller racing and leisure yachts became commonplace, down to the dinghy, a preferred training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
After the decade 1840–50, during which steam was set to emulate sail power in commercial vessels, the steam engine, and later the internal-combustion engine, were employed more and more in leisure yachts. Bigger power yachts were furthered to a high standard, and long-distance sailing became a favoured activity of the wealthy. The first power yachts were paddle-wheel boats; these then made way to yachts powered by the completely submerged screw or propeller kind of propulsion. As in the case of naval and merchant boats, auxiliaries possessing both sail and power were the yacht archetype for a number of years. By the latter half of the 20th century, many yachts were still auxiliaries, but the large part were only power yachts with gasoline or diesel engines.

In the last decade of the 19th century there was a rise in the design of large steam yachts. In particular of these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of at least 150. The Mayflower, commissioned 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 bigger and better quality internal-combustion engines were developed, many bigger yachts began using them for power. The creation of the diesel engine, using heavy oil for fuel, was furthered for World War I. In the decade following, bigger power-yacht creation grew, hitting a climax in the Orion (1930) at 3,097 tons. From that period the biggest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of bigger power craft declined after 1932, and the style from then was toward smaller, less costly yachts. From World War II, lots of small naval vessels were bought by private owners for conversion to yachts. At the late 20th century, yachting had become a internationally popular activity enjoyed by thousands of yachtsmen individually owning and upkeeping their own small recreational boats. The popularity of boats and yachtsmen has increased steadily, not only in the traditional places by the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are distinguished by the effect they have on the allocation of income and wealth. A proportional tax is a tax that puts the same relative onus on every taxpayer—i.e., where tax liability and income grow in equal levels. A progressive tax is characterizable by a higher than proportional increase in the tax liability in relation to the rise in income, and a regressive tax is recognisable by a less than proportional growth in the comparable onus. So, progressive taxes are viewed as taking away a lack of equality in income distribution, while regressive taxes can cause an increase in these inequalities.

The taxes that are usually regarded as progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, may become less so in the upper-income demographic—in particular if a taxpayer is able to lessen his tax base by claiming deductions or by excluding some income components from his taxable income. Proportional tax rates which are applied to lower-income categories will also be more progressive if such exemptions of a personal nature are claimed.

Income measured over the period of a given year may not definitely offer the best measure of taxpaying requirements. For example, transitory increases in income might be saved, and within temporary declines in income a taxpayer might select to finance consumption by reducing savings. Ergo, if taxation is regarded with “permanent income,” it should be less regressive (or more progressive) than if held in comparison with annual income.

Sales taxes and excises (except luxuries) are mostly regressive, because the portion of own income consumed or spent for a specific good decreases as the amount of personal income grows. Poll taxes (aka head taxes), nominated as a set amount per capita, clearly are regressive.

It is hard to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of the lack of certainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of nominating who bears the tax burden lays fundamentally on whether a national or a subnational (that is, provincial or state) tax is being decided.

In analysing the economic effect of taxation, it is relevant to distinguish between varied points of tax rates. The statutory rates include those dictated in law; generally these are marginal rates, but occasionally they are mean rates. Marginal income tax rates note the fraction of incremental income that is demanded by taxation when income increases by one dollar. Ergo, if tax burden rises by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax laws often contain graduated marginal rates—i.e., rates that rise as income rises. Structured analysis of marginal tax rates must review provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points greater than specified in the statutory rates. Since marginal rates indicate how after-tax income changes in response to changes in before-tax income, they are the relevant ones for considering incentive effects of taxation. It is even more difficult to nominate the marginal effective tax rate to apply to income from business and capital, because it may be reliant on factors such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem shows that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates indicate the fraction of total income that is paid in taxation. The pattern of average rates is the one that is relevant for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates usually grow with income, both because personal allowances are allowed for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other side of things, preferential treatment of income received for the most part by high-income households could dwarf these effects, producing regressivity, as indicated by average tax rates that decline as income increases.

The Development of Data Projectors

The LCDs used for projection systems are generally small reflective or transmissive panels set off by a bright arc lamp source. A number of lenses magnifies the reflected or transmitted image then displays it onto a screen. In front-projection systems the LCD is located on the same side of the screen as the viewer, although in rear-projection systems the screen is illuminated from behind. Projectors of greater cost and capacity might have three distinct LCD panels, forming separate red, green, and blue images that blend to make a coloured display on the screen.

The increasing need for visual displays has granted a growth in emphasis on the switching speed of liquid crystals. This has led to the invention of objects using smectic liquid crystals, certain kinds of which give a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most complex smectic device. Within it the liquid crystal molecules are managed in perpendicular layers to the substrate planes, which are distanced by one or two micrometres, and within the layers the molecules are on a tilt, as demonstrated in the figure. The host liquid crystal holds optically active molecules, and a scarcely perceptible consequence of the optical activity and the slant 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 within the plane of the layers. Thus, there is a permanent charge separation through 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 hence reverse the tilt direction of the molecules. The respective change in optical properties can cause a change from light to dark if or when one or more polarizers are utilised.

SSFLC devices have been marketed for big passive-matrix presentations, but their cost and complex detail has hindered them from enjoying any significant movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some promise for use as parts in projection systems or as viewfinders in digital cameras. Their quick response allows them to be utilised in time-sequential colour systems, in which dear colour filters are taken out for a coloured backlight that flashes red, green, and blue in quick speed (around 100 cycles a second). For example, the liquid crystal could be switched to a transmissive state for the red and green periods and then to a nontransmissive state in the blue period, with the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From each of the furniture objects, the chair may be paramount. While many other items (save for the bed) are created to support objects, the chair supports a human form. The term chair was regarded here in the common sense, from stool to throne to derivative makes including the bench or sofa, which might be considered 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 intriguing as its history as an art and craft. The chair is not merely a physical support or an aesthetic creation; it can also be semiotic of social status. At the historical royal courts there were significant distinctions between possessing a chair with arms, sitting on a chair with a back but without arms, or worse having to squat on a stool. In the last century, the director’s or manager’s chair has been an indicator of superior rank, and in democratic government meeting the speaker sits on a higher level.

In a furniture construction, the chair can be employed for a range of various forms. There are chairs structured to match man’s age and physical form (the high chair, the wheelchair) and to connotate his status in society (the executive chair, the throne). In historical days there were chairs used for birth (birth chairs); from the 20th century, there have been chairs used to die in (the electric chair). We have chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We have chairs that can be folded up, chairs on wheels, and chairs on runners.

Our lifestyle has demanded special chairs for automobiles and aircraft. Each of these chair types have been changed to conform to growing human uses. For its significant association with man, the chair exists to its full importance only when being used. Though it is not relevant to one’s appreciation of a cupboard or a set of drawers if there might be items inside or not, a chair is really understood and fairly judged with a person sitting on it, for chair and sitter require one another. Thus the different areas of a chair have been given names according to the elements of the human parts: arms, legs, feet, back, and seat.

Because the original purpose of the chair is to support our body, its value is evaluated generally for how suitably it does fulfill this practical job. Within the construction of a chair, the maker is bound in particular static regulation and principal measurements. Through these rules, however, the chair designer has extensive freedom.

The history of the chair covers dates of several thousand years. There is evidence of peoples that had significant chair forms, expressions of the highest task in the arenas of handling and design. Among these such peoples, a note 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 lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the construct of skilled craft, were found from tomb discoveries. First of these two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair has four legs crafted as akin to those of a chosen animal, a curved seat, and leading to a sloping back supported by vertical stretchers. In this way a solid triangular structure was obtained. There was to our knowledge no notable difference between the design of Egyptian thrones and chairs for ordinary people. The main difference lies in the complexity of ornamentation, in the choice of costly inlays. The Egyptian folding stool in all probability was designed to be an easily packed seat for army soldiers. As a camp stool the form existed til much later points. But the stool also then was designed as the task of a ceremonial seat, its original role as a folding stool ignored or forgotten. This can already be seen, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They were in the form of folding stools but are not able to be folded as the seats are created out of wood. The easy structure of the folding stool, made of two frames that rotate on metal bolts and support a seat of leather or fabric set between them, then appeared at some time later during the Bronze Age folding chairs of Scandinavia and northern Germany. The most well known of this kind is the folding stool, made from ashwood, which can now be found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is found not from any ancient object still existing but as in a wealth of pictorial material. The best recognised is the klismos seen on the Hegeso Stele at the Dipylon burial location near Athens (c. 410 BC). It is a chair that had a backward-sloping, curved backboard and four curving legs, only two of those can be shown. These strange legs were considered to be executed out of bent wood and were in that case had to bear great pressure under the weight of the sitter. The joints securing the legs to the frame of the seat would have been therefore super durable and were visibly indicated.

The Romans embued the Greek designs; quite a few statues of seated Romans offer evidence of a heavier and which appear to be a rather less intricately designed klismos. Both features, the light or heavy, were brought back in the Classicist era. The klismos chair can be found in French Empire design, in English Regency, and in particular kinds of considerable iconicism within Denmark and Sweden from 1800.

China
The past of the chair in China is not able to be tracked as far as the ancestry of chairs in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an unscathed collection of sketches and paintings had been protected, displaying the interior and outside of Chinese buildings and the kinds of furniture. Another preservation since the 16th century are a collection of chairs constructed from wood or lacquered wood, that possess an interesting likeness to pictures of past chairs.

Just like in Egypt, there existed two iconic chair forms in China: a chair with four legs and a folding stool. The four-legged chair has been seen both with and without arms though never missing its square seat and straight stiles (vertical side supports) to firm the back. In one design, it has been seen, the stiles could be lightly curved on top of the arms to fit the structure of the S-shaped back splat (the central upright of a chairback). Each of the three areas are mortised in the yoke-like top rail. Although the design of the back splat later had an introduction for English chairs of the Queen Anne period, wooden sections that could only to a restricted limit stabilise corner joints (and furthermore are loose in the bargain) signify a signature exclusive to Chinese chairs. The four legs sit through the seat frame, which finishes upon the rounded staves. All members are round in section or possesses rounded edges—acknowledging maybe to the bamboo tradition. The seat is uncomfortable and might have had a plaited seat. These chairs required of the sitter to be stiff and upright; for if too much pressure is placed on the back, the chair has a way of falling over. In patriarchal Chinese homes of this era armchairs likely were kept only for elderly individuals in the family, for they were greatly respected.

The Chinese folding stool is presumed to have been brought to China from the West. It is akin so very much from the Egyptian or Scandinavian folding stools, but it has a dissimilarity in that the top rail is elegantly joined to the two legs of the stool in a curved member, which is generally seen with metal mounts. From a Western viewpoint the overall effect of both furniture designs is stylized. The structure and decoration elements are combined in a manner that is both naïve and refined. The patched up appearance is an upshot of the fact that the individual items do not seem to have been affixed with either glue or screws, but have been mortised into one another and locked into its place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also put its signature on the chair. Works of art show 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 bring up a pattern of little pads. The front board and a similar board from the back could be folded after unscrewing some little iron hooks. Thus the chair was an easily portable piece of furniture when traveling which, during the same time, granted the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair is displayed in engravings of interiors of wealthy Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this kind of chair may also be seen in countries in which Dutch styles of interior decoration and Dutch furniture won preference, it is not decided that the style actually was instigated in The Netherlands. Generally, the legs of the chair were smooth, round in section, and of slender dimensions; they are occasionally baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was made in vast quantities, as can be seen from one of Abraham Bosse’s engravings, in which a whole row of such chairs lined up along a wall. The form asserts itself with its elegant 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 style—that is to say, as developed in Paris around 1750—conquered most of Europe and has been imitated or copied into the mid-20th century. The chair owes its popularity to a combination of relaxation and delicacy. The seat conforms to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are small upholstered pads on the armrests. Smooth transitions are found between seat frame, legs, and back conceal all the joints, which are solidly constructed on craftsmanlike methodology even with the absence of stretchers between the legs.

French Rococo chairs and imitations of them are constructed from wood of rather thick density; but all members are deeply molded, all extraneous wood has been sanded away, and more expensive examples may be further embellished with highly delicate and decorative engravings. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for all of the upholstery on the seat, back, and armrests; crosshatched cane is in some cases used as an alternative to upholstery.

English chairs in the 18th century were more open in design than the French. The French taste for stylistic uniformity, which came from the highest circles in Paris and Versailles throughout most of France and was popularised 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 popular 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 versions 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 recording of the money values of the operation of a business. Bookkeeping creates the figures from which accounts are prepared but is a previous process, prior to accounting.

Predominantly, bookkeeping finds two parts of information: (1) the current value, or equity, of a business and (2) the change in value—profit or loss—taking place in the entity over a particular time.

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

Traces of financial and numerical record charts are found for just about every group of people with a commercial background. Records of business contracts were found in the archaelogical digs of Babylon, and accounts for both farms and estates were held in ancient Greece and Rome. The dual-entry method of bookkeeping came with the progression of the business republics of Italy, and manuals for bookkeeping were produced during the 15th century in many Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made perfect financial books a paramount factor. The ancestry of bookkeeping, in fact, resembles the ancestry of commerce, industry, and government and, in some part, assisted in shaping it. The global spread of industrial and commercial activity demanded greater sophisticated decision-making methodology, which in its turn called for more sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government legislature became more significant and resulted in greater requirement for information; enterprising firms had to have information available to go with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also developed in size, and the need for bookkeeping for departmental operations increased.

While bookkeeping procedures can be rather detailed, all are based on two kinds of books utilised in the bookkeeping procedure—journals and ledgers. A journal must have the daily transactions (sales, purchases, etcetera), and the ledger has the record of individual accounts. The daily records in the journals are entered in the ledgers.

Each month, generally speaking, an income statement and a balance sheet are prepared from the trial balance posted in the ledger. The purpose of the income statement or profit-and-loss statement is to present an analysis of the changes that have occurred in the business equity from the transactions of the period. The balance sheet displays the financial position of the corporation at the 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 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.
