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

The most typical question that is asked when acquiring a new projector for the home, office, or classroom is: would 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 types available, it can be difficult for clients to make a decision between both technologies. The simple fact of the matter is that LCD projectors give superior image quality and colour accuracy. The following article will tell you why DLP projectors struggle with bringing up a similar level of image quality.

It’s like a set of blinds in your house on 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. That is exactly how an LCD projector operates. Each pixel operates like an individual shutter on a set of blinds to either send light through or to block it. DLP on the other hand is made up of millions of microscopic mirrors or ‘pixel elements’ as the 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 vitally important with regard to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by splitting it into red, blue and green components, by three mirrors which transfer the coloured light to 3 individual LCD panels. The 3 LCD panels create the elements of the image by switching each pixel on and off. The pixels are then projected in a glass prism to send the projector image. A significant point to realise about LCD projectors is that all three colours are delivered onto your projector screen simultaneously. The way a DLP projector runs is very different and even the way an image appears is not the same. With DLP, white light from the lamp is sent through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of projecting an image requires a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to produce the image elements. The elements of the image are sent in sequence on the screen, one colour at a time. The viewer’s eye will then combine each coloured element of the image into a full image. In LCD projectors, all colours are available all the time to form high brightness and spectacular colour accuracy. In DLP, just one colour is available at a time, resulting in lower colour brightness and accuracy. Some manufacturers have put a white segment in the colour wheel to improve all over brightness, but this goes and degrades colour accuracy.

I read in forums all the time that DLP provides a higher contrast ratio and therefore must be better. 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 able to produce. DLP projectors do have high contrast specifications in comparison to the majority of LCD projectors. At first glance, this can seem to be a plus, however, in reality, the true black level is determined by the ambient light in the room where the projector is used. Do not be fooled by contrast specifications on websites and in brochures.

When the content you plan to project has moving images, DLP projection technology also has image marks, or ‘artifacts’. The most typical artifact that a DLP projector forms 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 projected. LCD projectors do not have this downside because all the colours are processed with the others. DLP developers have come up with 3DLP solutions using 3 chips to solve the colour break up error, but the price of these projectors make them not practical for many businesses and consumers.

Another difference between LCD and DLP is how they match the balance for the refractive qualities of light. Jump back to high school science, and recall how various colours of light refract varied amounts when projected through the same lens. The downfall with DLP projectors is that they use the one same panel for the same lens to project Red, Blue and Green. All 3 colours are different and refract light at different levels. Usually with a DLP projector, a spill of yellow colour will show above and a spill of blue will come through below an image as simple as a lone black line. While being built LCD projectors can be fixed to reduce these effects on the projected image, as each colour is processed on separate LCD panels.

The sole real advantage (excluding price) with buying a DLP projector is its smaller size and weight. However, this is only relevant to mobility and must be traded off against the image superiority of LCD projectors. If overall picture quality is important to you, then the answer is no-brainer. Take an LCD projector! LCD projectors will consistently show bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch found dominance in sea power during the 17th century, the early yacht became a leisure craft used mostly by royalty and then by the burghers on the canals and the protected and unprotected waters of the Low Countries. Yacht racing was incidental, borne from private matches. English yachting originated with King Charles II of England during his exile in the Low Countries. On his restoration to the English monarchy 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 then named 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 wager. Yachting became popular among the wealthy and royalty, but after that period the trend did not last.

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

Yacht racing began in some stipulated method on the Thames in the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV rose to sovereignty in 1820, it was then known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht association had been started 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 continuing site of British yacht racing. The club at Cowes became the Royal Yachting Club, also at the ascension of George IV. All members were required to own boats of at least 20 tons (20,321 kg). Sailing races for high bets were held, and the social life was splendid. 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 had dominance. Sailing was for the most part for leisure and rose to its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and created a standard of luxury and sophistication for the later yachts in those waters from the late 19th century. The first continuing American yacht club, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens instigated the New York Yacht Club while on board his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts followed the style of such naval craft as brigantines, schooners, and cutters from the 17th century through to the later half of the 19th century. The style of sizeable yachts was first heavily impacted by the success 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.) found its namesake after its win at Cowes in 1851. The first 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 known as naval architecture come into action. Not until the 1920s did the application of the science of aerodynamics do for the craft of sails and rigging what it had already done for hulls.

Because nearly all sailboats had to be individually manufactured, there arose a requirement for handicapping boats before the one-design class boats were built. Therefore, a rating rule was written, which is found in the International Rule, accepted in 1906 and revised in 1919. In the present day, 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 the same specifications in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing these boats can be held on an even playing field 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.

For the time that yachting was done mostly for the royal and the affluent, cost was no object, and the size of boats increased, in both length and weight. The promotion and desire of smaller yachts 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 trip around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the seaworthiness of smaller yachts. Following this in the 20th century, notably after World War II, smaller racing and recreational yachts 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
After the decade 1840–50, during which steam started to emulate sail power in public craft, the steam engine, and later the internal-combustion engine, were used increasingly in pleasure boats. Sizeable power yachts were furthered to a high degree, and long-distance travel was a favoured occupation of the rich. The earliest power yachts were paddle-wheel boats; they then gave rise to those powered by the completely submerged screw or propeller sort of propulsion. As well as naval and merchant boats, auxiliaries with both sail and power were the yacht archetype for several years. By the later half of the 20th century, several yachts were still auxiliaries, but the majority were solely power yachts that had gasoline or diesel engines.

From the last decade of the 19th century there was a push in the design of more sizeable steam yachts. Notably among 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 over 150. The Mayflower, bought by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and saw active service in World War II.

As bigger and better quality internal-combustion engines were created, many big yachts were using them for power. The development of the diesel engine, using heavy oil for fuel, advanced from World War I. From the decade that followed, large power-yacht creation blossomed, 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 building of big power craft lessened in 1932, and the fashion after that was for smaller, less pricey yachts. Following World War II, many small naval vessels were traded by private owners for conversion to yachts. In the late 20th century, yachting had become a globally beloved sport enjoyed by thousands of yachtsmen who are actually sailing and upkeeping their own small recreational yachts. The popularity of craft and yachtsmen increased steadily, not only in the traditional places along the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be categorized by the effect they have on the distribution of income and wealth. A proportional tax is the kind that applies the same relative burden on each taxpayer—i.e., where tax liability and income grow in the same scale. A progressive tax is recognised by a greater than proportional increase in the tax liability relative to the increase in income, and a regressive tax is recognisable by a less than proportional rise in the relative liability. Therefore, progressive taxes are seen as fighting inequity in income distribution, but regressive taxes are seen to increase these inequalities.

The taxes that are usually regarded as progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, may become less so in the upper-income categories—particularly if a taxpayer is permitted to reduce his tax base by declaring deductions or by removing particular income elements from his taxable income. Proportional tax rates that are applied to lower-income categories can also be more progressive if personal exemptions are declared.

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

Sales taxes and excises (excepting luxuries) are mostly regressive, because the spread of one’s income consumed or spent for specific goods decreases as the level of personal income rises. Poll taxes (aka head taxes), nominated as a fixed amount per capita, clearly are regressive.

It is not easy to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to the lack of certainty about the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden is dependant fundamentally on whether a national or a subnational (that is, provincial or state) tax is being debated.

In assessing the economic effect of taxation, it is important to differentiate between several ideas of tax rates. The statutory rates will include those nominated in the law; usually these are marginal rates, but for some cases they are average rates. Marginal income tax rates signify the fraction of incremental income that is demanded by taxation when income grows by one dollar. Thus, if tax onus grows by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax regulations usually contain graduated marginal rates—i.e., rates that grow as income rises. Careful analysis of marginal tax rates are required to consider provisions as well as 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 more than specified by the statutory rates. Since marginal rates signify how after-tax income moves in response to changes in before-tax income, they are the important ones for considering incentive effects of taxation. It is even more complicated to nominate the marginal effective tax rate applied to income from business and capital, because it may rely on such considerations 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 nil under a consumption-based tax.

Average income tax rates signify the fraction of total income that is paid in taxation. The pattern of average rates is the one that is in consideration for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates commonly rise with income, both because personal allowances are provided for the taxpayer and dependents and because marginal tax rates are graduated; on the other hand, preferential treatment of income received mostly by high-income households might dwarf these effects, producing regressivity, as signified by average tax rates that lessen as income increases.

The Development of Data Projectors

The LCDs used for projection systems are usually small reflective or transmissive panels lit by a bright arc lamp source. A series of lenses magnifies the reflected or transmitted image and then casts it on a screen. For front-projection systems the LCD is situated on the same area of the screen as the viewer, while in rear-projection systems the screen is lit from behind. Projectors of higher cost and capacity sometimes have three discrete LCD panels, forming separate red, green, and blue images that combine to reflect a coloured image on the screen.

The growth in need for visual displays has had a growth in emphasis on the switching speed of liquid crystals. This has demanded the development of items build with smectic liquid crystals, certain ones of which have a quicker electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most progressive smectic device. With 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 slanted, as demonstrated in the figure. The host liquid crystal contains optically active molecules, and a minor result of the optical activity and the angle of the molecules is the presence 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 throughout the plane of the layers. So, there has to be a permanent charge separation through 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 respective change in optical properties can cause a change from light to dark if or when one or more polarizers are used.

SSFLC devices have been publicized for large passive-matrix presentations, but their cost and complexity has prevented them from enjoying any great progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some probability for use as aspects in projection systems or as viewfinders in digital cameras. Their quick reaction allows them to be employed in time-sequential colour systems, in which highly expensive colour filters are emulated with a coloured backlight that flashes red, green, and blue in quick speed (about 100 cycles every second). For example, the liquid crystal might be switched to a transmissive state between the red and green periods 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

Out of each of the furniture forms, the chair might be the most imperative. While most other forms (except the bed) are meant to support objects, the chair supports your human form. The term chair was viewed here in the larger sense, from stool to throne to derivative chairs for example a bench and sofa, which should be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently distinuishable.

The social history of the chair is as stimulating as its history as a creative craft. The chair is not simply a physical support and/or aesthetic piece of art; it historically is symbolic of social placement. Within the old royal courts there were plain signifiers between being seated on a chair with arms, on a chair with a back but no arms, or having to use a stool. Since the last century, the director’s or manager’s chair has been regarded as a symbol of superior dignity, and even in democratic government debate the speaker sits on an elevated floor.

In its furniture creation, the chair is utilised for a wealth of different forms. There are chairs manufactured to match man’s age and physical form (the high chair, the wheelchair) and for his standing in society (the executive chair, the throne). In the olden days there were chairs for birthing (birth chairs); since the 20th century, there have been chairs used for ending life (the electric chair). We design chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We can have chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has developed particular chairs for use in automobiles and aircraft. All of these chair shapes have been perfected to conform to different human requirements. Due to its particular association with man, the chair comes to its full purpose only when in employ. Though it is not relevant to one’s appreciation of a cupboard or a chest of drawers if there are items inside or not, a chair is understood best and clearly evaluated by a person utilising it, because chair and sitter complement each other. Thus the several limbs of a chair were given labels corresponding to the limbs of our human form: arms, legs, feet, back, and seat.

Because the clear role of the chair is to support a human body, its value is tested basically from how suitably it does fulfill this practical job. In the design of a chair, the chair maker is bound by the static law and principal measurements. In these boundaries, however, the chair designer has marvellous freedom.

The history of the chair was an era of several thousand years. There is evidence of peoples that created individual chair types, seen of the highest object in the areas of handling and creativity. From these such societies, a mention needs to be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the upshot of careful craft, are seen from tombs. The first of these two is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair would have had four legs structured akin to those of a particular animal, a curved seat, with a sloping back supported over vertical stretchers. In this design a solid triangular design was obtained. There appeared to be no notable variation from the creation of Egyptian thrones and chairs for regular peasantry. The real change existed in the complexity of ornamentation, in the selection of pricey inlays. The Egyptian folding stool in all probability was designed as an easily packed seat for army. As a camp stool the form continued for much later periods of time. But the stool then took on the character of a ceremonial seat, its original task as a folding stool ignored or forgotten. This can now be found, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They are made in the form of folding stools but can’t be folded as the seats were formed of wood. The simplistic build of the folding stool, composed of two frames that spin on metal bolts and support a seat of leather or fabric held between them, was seen again but somewhat later as the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognised of those is the folding stool, crafted from ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The iconic Greek chair, the klismos, is seen not with any ancient item still in form but from a variety of pictorial material. The better known is the klismos seen on the Hegeso Stele at the Dipylon burial location in outer Athens (c. 410 BC). This is a chair that had a backward-sloping, curved backboard and four curving legs, only two of which could be visible. These strange legs were considered to have been created from bent wood and were thus put under a large amount of pressure with the weight of the sitter. The joints joining the legs to the frame of the seat had to be therefore extremely solid and were overtly indicated.

The Romans emulated the Greek designs; a number of statues of seated Romans are examples of a thicker and which appear to be a slightly crudely built klismos. Both features, the light or the heavy, were brought back as part of the Classicist period. The klismos style is found in French Empire design, in English Regency, and in particular kinds of notable individuality within Denmark and Sweden circa 1800.

China
The history of the chair in China isn’t able to be traced as far as the ancestry of chairs in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unbroken series of drawings and artworks was kept safe, detailing the inside and outside of Chinese houses and their furniture. Preserved also from the 16th century are a collection of chairs of wood or lacquered wood, that show an intriguing resemblance to images of past chairs.

As was the case in Egypt, there existed two major chair designs in China: a chair of four legs and a folding stool. That four-legged chair was seen both with and without arms but never missing the square seat and straight stiles (standing side supports) to hold up the back. In one form, it has been found, the stiles were lightly curved on top of the arms in order to fit the form of the S-shaped back splat (the central upright of a back). All three limbs were mortised into the yoke-like top rail. Though the style of a back splat later had an introduction for English chairs within the Queen Anne period, wooden items that would only to a particular capability reinforce corner joints (and furthermore were loose additionally) are an element particular to Chinese chairs. The four legs pass through the seat frame, which ends around the rounded staves. All members are round in section or has rounded edges—an acknowledgement perhaps to the bamboo tradition. The seat is not pleasant and may have a plaited texture. These chairs needed the sitter to stay stiff and upright; when too much weight is forced on the back, the chair has a tendency to fall. In patriarchal Chinese households of this epoch armchairs presumably were only for the senior individuals, for they were esteemed greatly.

The Chinese folding stool is presumed to have travelled to China from the West. It does not differ so very much from the Egyptian and Scandinavian folding stools, but it possesses a variation in that the top rail is delicately joined to the two legs of the stool in a curved member, which is often designed with metal mounts. From a Western viewpoint the ultimate effect of these furniture items is stylized. The constructive and aesthetic parts are combined in a way that is both naïve and refined. The piecemeal appearance is an upshot of the way that the individual parts do not appear to have been fixed together by means of either glue or screws, but were mortised onto one another and locked into position in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also left its name on the chair. Works of art show a kind of chair with a relatively crude wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing between the layers, stitched to produce a pattern of tiny pads. The front board and a similar board in the back could be folded after loosening some tiny iron hooks. In this way the chair was a portable piece of furniture in traveling which, during the same time, possessed 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 the interior of affluent Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this type of chair may also be made in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not decided that the design actually originated in The Netherlands. Normally, the legs of the chair are smooth, round in section, and of slim measurements; they are in some cases baluster-shaped (vase-shaped) or twisted. It is unquestionably a bourgeois piece of furniture and was made in vast quantities, as can be surmised from one of Abraham Bosse’s engravings, in which there is an entire row of these chairs lined up along a wall. The style asserts itself with its harmonious proportions and expensive 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 was, to say, as created in Paris around 1750—spread through most of Europe and was imitated or copied in the mid-20th century. The model owes the popularity to a combination of comfort and charm. The seat adheres to the human body and grants a relaxed sitting position. The back is bow-shaped, the legs curved. Typically the seat and back are upholstered, and there are little upholstered pads over the armrests. Smooth transitions made between seat frame, legs, and back disguise all the joints, which are constructed on craftsmanlike practices despite the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are made from wood of fairly thick density; but every member is deeply molded, all extra wood has been sanded away, and more expensive designs can be further embellished with intricately delicate and decorative carving. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for the upholstery on the seat, back, and armrests; cane is in some cases used instead of upholstery.

English chairs from the 18th century were more variable in form than the French. The French preference for stylistic uniformity, which lead from the premier circles in Paris and Versailles through most of France and won favour 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 commonly known and was widely distributed throughout the world.

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

In cheaper 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, hint 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 gives the information from which accounts are made but is a different process, required prior to accounting.

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

Management officials, investors, and credit grantors all require this information: management in order to understand the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to analyse the outcomes of business operations and make decisions for buying, holding, and selling securities; and credit grantors in order to regard the financial statements of a business in judging whether to accept a loan.

Bits and pieces of financial and numerical recordkeeping are uncovered for almost every civilization with a commercial backbone. Records of commercial contracts have been discovered in the remains of Babylon, and accounts for both farms and estates had been created in ancient Greece and Rome. The dual-entry manner of bookkeeping started with the development of the entrepeneurial republics of Italy, and tutorial books for bookkeeping were produced within the 15th century in some Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made factual financial recordkeeping a requirement. The ancestry of bookkeeping, in fact, resembles closely the history of commerce, industry, and government and, in part, helped in shaping it. The worldwide market of industrial and commercial activity called for better cosmopolitan decision-making procedures, which then required better sophistication in the selection, classification, and presentation of information, increasingly with the assistance of computers. Taxation and government legislation became more detailed and resulted in increased demand for information; enterprising firms had to show available information to support 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 own inner departmental operations went up.

Though bookkeeping processes can be very complex, it is all based on two kinds of books utilised in the bookkeeping process—journals and ledgers. A journal must have the daily transactions (sales, purchases, and such), and the ledger contains the record of individual accounts. The daily records kept in the journals are put in the ledgers.

At the end of every month, as a general rule, an income statement and a balance sheet are created from the trial balance posted from the ledger. The purpose of the income statement or profit-and-loss statement is to present an analysis of any changes that have occurred in the enterprise equity as a result of the events of the period. The balance sheet provides the financial position of the corporation at the particular date taken from assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

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

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

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

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

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

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

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

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

Today the wheel has turned full circle. In the past 10 to 20 years there has been a powerful wish to get back to the ‘eyeball-to-eyeball’ type of confrontation of the man in the Sopwith Camel. The pre-eminent Western fighter, the McDonnell Douglas F-4 Phantom, was rebuilt with an internal gun, a rapid-fire 20 mm (0.79 in) cannon with six barrels firing up to 6,000 rds/ min, and a slatted wing to pull tighter turns in combat.

New small fighters appeared, such as the General Dynamics F-16, which, although bigger and heavier than any single-engined fighters of World War II, are nevertheless small and light by comparison with such impressive machines as the Grumman F-14 Tomcat, McDonnell Douglas F-15 Eagle, and MiG-25 Foxbat, The RAF’s next interceptor, the ADV (Air-Defence Version) of the Panavia Tornado, is a careful midway compromise, smaller than the three monsters just listed, but with two engines, long range, powerful radar, and extremely effective Skyflash missiles.

Modern interceptors defend vast blocks of airspace up to 160 km (100 miles) in radius, with powerful radar able to look down at the surrounding land and water and spot low-flying intruders trying to slip through the defences unnoticed. Their task is eased by the presence of special surveillance, early-warning, and AWACS (Airborne Warning and Control System) aircraft, with enormous radars and sophisticated command and control systems to manage all a nation’s defences in the most efficient way.

There is no better feeling than being in the cockpit during your jet fighter flight. Jet fighter flights and jet fighter joy flights are the ultimate gift giving and receiving experience that will be remembered forever.
