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

The most common question that is asked when looking for 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, an acronym for ‘digital light processing’ are the two top projector imaging technologies. With so many brands and models available, it can be challenging for the buyer to choose between the two technologies. Ultimately LCD projectors offer better image quality and colour accuracy. The following article explains why DLP projectors struggle with creating the same grade of image quality.

Imagine a set of blinds in your household covering your bedroom window. By a twist of a rod you can turn the shutters open or closed, according to whether you want to let light in or not. That is exactly how an LCD projector functions. Each pixel functions like its own 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 experts like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the point when the projector is switched on to when the image reaches your screen is extremely significant in regard to image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by dividing it into red, blue and green components, by three mirrors which project the coloured light to 3 stand alone LCD panels. The 3 LCD panels create the elements of the image by processing each pixel on and off. The pixels are then projected in a glass prism to form the projector image. An important point to understad about LCD projectors is that all three colours are directed onto your screen at once. The way a DLP projector runs is vastly different and even the produced image comes out 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 method of making an image creates a sequence of red, blue and green light. The millions of micro mirrors described above reflect the coloured light on the pixels to form the image elements. The elements of the image are cast in sequence on the screen, one colour at a time. The viewer’s eye will then combine each coloured element of the image into the total image. With LCD projectors, all colours are available all the time to deliver high brightness and great colour accuracy. In DLP, only one colour is available at a time, and so resulting in lower colour brightness and accuracy. Some developers have included a white segment for the colour wheel to improve brightness overall, but this then degrades colour accuracy.

I hear in forums all the time that DLP gives a higher contrast ratio and ergo must be superior quality. 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 technology is able to produce. DLP projectors do provide high contrast specifications as compared to most LCD projectors. At a glance, this appears to be a benefit, however, in real life, the true black level is determined by the ambient light in the room in which the projector is used. Do not be tricked by contrast specifications on websites and in brochures.

When the content you wish to bring to life has moving images, DLP projection technology can also have image imperfections, or ‘artifacts’. The most often seen artifact that a DLP projector displays with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images keep changing between the time red, blue and green colours are projected. LCD projectors do not have this disadvantage because all colours are sent at once. DLP builders have formed 3DLP solutions using 3 chips to solve the colour break up issue, but the cost of these projectors make them almost impossible for most businesses and consumers.

Another differentiation between LCD and DLP is how they match the balance for the refractive qualities of light. Take yourself back to high school science, and recall how the different colours of light refract different amounts when shone through the same lens. The problem with DLP projectors is that they utilise the one same panel for the same lens to project Red, Blue and Green. All 3 colours are different and refract light in a different way. Often with a DLP projector, a superfluous yellow colour will show above and some blue will come up below something as simple as a lone black line. In building LCD projectors can be set to remove these effects on the projected image, because each colour is projected on isolated LCD panels.

The sole true benefit (excluding price) with deciding on a DLP projector is its smaller total size and weight. However, this is only relevant in regard to mobility and cannot be traded off against the image superiority of LCD projectors. If the result of the picture quality is crucial to you, then the decision is simple. Go for an LCD projector! LCD projectors will always create bright, colourful images with fewer image imperfections.

Yachting and Yacht Clubs

As the Dutch came to preeminence in sea power during the 17th century, the initial yacht became a pleasure craft used first by royalty and secondly by the burghers for the canals and then in the protected and unprotected waters of the Low Countries. Racing was incidental, coming out of private challenges. English yachting originated 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 more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and the same way back, on a £100 bet. Yachting was found to be popular for the rich and nobility, but after that time the fashion did not last.

The first yacht club in the British Isles, the Water Club, was started in about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, with large naval panoply and rigour. The closest thing to a race was the “chase,” when the “fleet” pursued an imagined enemy. The club endured, largely as a social club, until 1765, and in 1828, by conglomerating with other clubs, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was seen in some organized fashion on the Thames about the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV rose to the throne in 1820, it was known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing dispute, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been started at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the perpetual site of British yacht racing. The association at Cowes became the Royal Yachting Club, also at the accession of George IV. Each member was required to own boats of at least 20 tons (20,321 kg). Sailing tests for high bets were held, and the club life was lovely. Eventually Royal Yachting Club boats were raised in size to over 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and continued when the English gained control. Sailing was largely for pleasure and found its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and established a minimum of luxury and sophistication for the later yachts in that area from the late 19th century. The first persisting American yacht association, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts were within the style of such naval craft as brigantines, schooners, and cutters from the 17th century through the second half of the 19th century. The design of sizeable yachts was first largely put upon by the victory of America, which was designed by George Steers for a club led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its victory at Cowes in 1851. The first yachts were not designed and manufactured in the modern sense, with only a model for an outline. Not until the second half of the 19th century did what was called naval architecture come about. Not until the 1920s did the use of the study of aerodynamics do for the craft of sails and rigging what it had earlier done for hulls.

Because almost all sailboats were individually manufactured, there came a desire for handicapping boats before the one-design class boats were designed. Hence, a rating rule was decreed, which is found in the International Rule, taken on in 1906 and revised in 1919. In the present day, one of the most rapidly flourishing areas in sailing is that of one-design class boats. All boats in a one-design class are created to the same requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing for such boats can be held on an even keel with no handicapping required. A prime example is the generic International America’s Cup Class taken on board for yachts in the 1992 America’s Cup race.

For the time that yachting was an activity primarily for the aristocracy and the affluent, cost was no problem, and the size of boats grew, in both length and weight. The promotion and popularity of smaller yachts occurred in the later half of the 19th century in the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A trip around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the value of smaller yachts. Thereafter in the 20th century, for the larger part after World War II, smaller racing and pleasure boats became more common, down to the dinghy, a preferred 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
Post the decade 1840–50, at which point steam started to emulate sail power in market vessels, the steam engine, and later the internal-combustion engine, were favoured increasingly in leisure boats. Large power yachts were furthered to a high degree, and long-distance cruising became a favoured pastime of the wealthy. The earliest power yachts were paddle-wheel boats; they then gave rise to those powered by the wholly submerged screw or propeller kind of propulsion. As in the case of naval and merchant craft, 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 large part were solely power yachts containing gasoline or diesel engines.

From the last decade of the 19th century there was a push in the construction of more sizeable steam yachts. Notably of these was the Mayflower (1897) of 2,690 tons, that had triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of more than 150. The Mayflower, purchased by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and saw active service during World War II.

As more sizeable and more reliable internal-combustion engines were created, many big boats started using them for power. The creation of the diesel engine, employing heavy oil for fuel, was furthered from World War I. From the decade that followed, bigger power-yacht manufacture flourished, reaching a climax in the Orion (1930) at 3,097 tons. In that time the biggest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of larger power yachts declined in 1932, and the style from then was toward smaller, less costly yachts. Following World War II, a lot of small naval craft were bought by private owners for conversion to yachts. At the late 20th century, yachting is a internationally popular competition enjoyed by thousands of yachtsmen personally manning and maintaining their own small leisure craft. The number of yachts and yachtsmen is increasing steadily, not only in the traditional locations by the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be distinguished by the impact they have on the placement of income and wealth. A proportional tax is one that places the same relative requirement on all taxpayers—i.e., when tax liability and income increase in the same proportion. A progressive tax is characterized by a higher than proportional rise in the tax burden in relation to the increase in income, and a regressive tax is characterizable by a less than proportional increase in the related liability. Ergo, progressive taxes are seen as removing inequity in income distribution, while regressive taxes may have the effect of an increase in these inequalities.

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

Income measured over the course of a given period may not definitely come up with the most accurate measure of taxpaying ability. For example, transitory growth in income could be saved, and during temporary declines in income a taxpayer might choose to finance consumption by decreasing savings. Therefore, if taxation is held in comparison alongside “permanent income,” it will be less regressive (or more progressive) than if it is held in comparison with annual income.

Sales taxes and excises (excepting luxuries) are usually regressive, because the share of personal income consumed or spent for a specific good lessens as the rate of personal income rises. Poll taxes (also known as head taxes), nominated as a fixed amount per capita, obviously are regressive.

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

In regarding the economic effects of taxation, it is important to differentiate between several concepts of tax rates. The statutory rates will include those nominated in law; often these are marginal rates, but occasionally they are average rates. Marginal income tax rates denote the fraction of incremental income that is demanded by taxation when income is increased by one dollar. Therefore, if tax onus grows by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax statutes commonly contain graduated marginal rates—i.e., rates that rise as income grows. Careful analysis of marginal tax rates must consider provisions other than the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) falls by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than specified in the statutory rates. Since marginal rates indicate how after-tax income moves in response to changes in before-tax income, they are the necessary ones for appraising incentive effects of taxation. It is even more complicated to realise the marginal effective tax rate applied to income from business and capital, as it may be reliant on such factors 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 nothing under a consumption-based tax.

Average income tax rates show the percentage 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 generally increase with income, both because personal allowances are granted for the taxpayer and dependents and also because marginal tax rates are graduated; on the flip side, preferential treatment of income received for the most part by high-income households could swamp these effects, allowing regressivity, as signified by average tax rates that fall as income rises.

The Development of Data Projectors

The LCDs built in projection systems are generally small reflective or transmissive panels illuminated by a strong arc lamp source. A number of lenses magnifies the reflected or transmitted image then casts it on a screen. With 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 lit up from behind. Projectors of more expense and capacity sometimes use three distinct LCD panels, forming separate red, green, and blue images that blend to form a coloured image on the screen.

The growth in demand for video displays has had a special emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of devices using smectic liquid crystals, some types of which give a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most developed smectic device. With it the liquid crystal molecules are set out in layers perpendicular to the substrate planes, which are distanced by one or two micrometres, and inside the layers the molecules are tilted, as illustrated in the figure. The host liquid crystal contains optically active molecules, and a scarcely perceptible result of the optical activity and the tilt of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, likeable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and within the plane of the layers. Therefore, there has to be a permanent charge separation across the liquid crystal layer in the SSFLC, and its sign is directly partnered to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and by doing so reverse the tilt direction of the molecules. The respective change in optical properties can create a change from light to dark in the case that one or more polarizers are employed.

SSFLC devices have been produced for big passive-matrix presentations, but their expense and complex detail has impeded them from enjoying any great effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have some promise for use as parts in projection systems or as viewfinders in digital cameras. Their speedy response allows them to be utilised in time-sequential colour systems, in which high cost colour filters are replaced by a coloured backlight that flashes red, green, and blue in fast pace (around 100 cycles every second). For example, the liquid crystal might be switched to a transmissive state in the red and green periods but to a nontransmissive state during the blue period, having the end result 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 primary. While most other forms (apart from the bed) are designed to support objects, the chair supports your human form. The term chair is used here in the most general sense, from stool to throne to developed kinds for example a bench or sofa, which may be looked upon as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly distinguished.

The social history of the chair is as interesting as its history as an art and craft. The chair is not just a physical support and aesthetic object; it is also an indicator of social placement. In the Medieval royal courts there were significant connotations between being seated on a chair with arms, or a chair with a back but without arms, or having to utilise a stool. In the last century, the director’s and manager’s chair has been an identifier of superior rank, and in democratic government debate the speaker sits on a high-set level.

As its furniture creation, the chair encompasses a wealth of different makes. There are chairs manufactured to attend to man’s age and physical condition (the high chair, the wheelchair) and to connotate his position in society (the executive chair, the throne). In historical times there were chairs for births (birth chairs); in the 20th century, there have been chairs to die in (the electric chair). We make chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We make chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has designated particular chairs for automobiles and aircraft. All these chair shapes have changed to conform to different human desires. Because of its particular relationship with man, the chair exists to its full meaning only when in use. Though it is not relevant to one’s appreciation of a cupboard or a chest of drawers if there are things inside or not, a chair is understood best and fairly regarded with a person using it, for chair and sitter require one another. Thus the different areas of a chair are labeled according to the areas of the human form: arms, legs, feet, back, and seat.

Because the principal work of a chair is to support the human body, its credit is judged firstly by how completely it does measure up to this practical role. Within the structure of the chair, the chair maker is restricted under some static regulations and principal measurements. Inside these boundaries, however, the chair builder has large freedom.

The history of the chair is a period of several thousand years. There is evidence of peoples that had made individual chair forms, expressive of the highest task in the arenas of technique and aesthetics. Within such peoples, particular note can be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the result of careful scheme, are now found from tombs. First of these two is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair would have had four legs formed similar to those of a chosen animal, a curved seat, leading to a sloping back supported from vertical stretchers. In this way a stable triangular form was created. There was to all appearances no noteworthy change between the design of Egyptian thrones and chairs for regular people. The main difference existed in the kind of ornamentation, in the evidence of costly inlays. The Egyptian folding stool most likely was developed for an easily packed seat for army. As a camp stool that kind stayed around until much later points. But the stool then was made as the task of a ceremonial seat, its original role as a folding stool fast forgotten. This can from today’s evidence be observed, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were in the construction of folding stools but are not able to be folded as the seats are created from wood. The plain construction of the folding stool, consisting of two frames that turn on metal bolts and bear a seat of leather or fabric set between them, is seen at some time later as the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of this form is the folding stool, crafted from ashwood, which is now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The iconic Greek chair, the klismos, is seen not from any ancient item still in form but as seen in a large amount of pictorial objects. The significant kind is the klismos posited on the Hegeso Stele at the Dipylon burial place by Athens (c. 410 BC). It is a chair that had a backward-sloping, curved backboard and four curving legs, only two of these legs would be displayed. These creative legs were most likely to have been created with bent wood and were probably put under a large amount of pressure from the weight of the sitter. The joints joining the legs to the frame of the seat would have been therefore very solid and were particularly pointed out.

The Romans embued the Greek design; a number of statues of seated Romans are evidence of a heavier and apparently slightly less delicately designed klismos. Both features, light or heavy, were seen again within the Classicist time. The klismos chair is found in French Empire design, in English Regency, and in particular brands of notable individuality of Denmark and Sweden circa 1800.

China
The progression of the chair in China is not able to be tracked as far back as chairs in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) a full series of sketches and works of art had been kept safe, displaying the insides and outer parts of Chinese households and their furniture. Also kept of the 16th century are some chairs crafted from wood or lacquered wood, that bear an amazing likeness to styles of ancient chairs.

Just like in Egypt, two chair designs dominated in China: a chair of four legs and a folding stool. That four-legged chair is constructed both with and without arms but always with a square seat and straight stiles (standing side supports) to firm the back. In one design, though, the stiles were lightly curved by the arms in order to suit the angle of the S-shaped back splat (the centre upright of its chairback). Each of the three limbs are mortised onto the yoke-like top rail. Despite that the style of a back splat exercised an inspiration for English chairs from the Queen Anne period, wooden items that only just to a limited extent stabilise corner joints (and then are loose into the bargain) signify a feature exclusive to Chinese chairs. The four legs sit through the seat frame, which stops over the rounded staves. All members are round in section or possesses rounded edges—references maybe to the bamboo tradition. The seat is not comfortable and might have had a plaited texture. These chairs demanded of the sitter to be stiff and upright; when too much pressure is pushed on the back, the chair has a way of falling over. In patriarchal Chinese homes of this era armchairs probably were only for senior people in the family, for they were greatly respected.

The Chinese folding stool is believed to have taken to China from the West. It is not dissimilar very much from the Egyptian or Scandinavian folding stools, but it possesses a change in that the top rail is prettily held to the two legs of the stool with a curved member, which is usually seen with metal mounts. From a Western perspective the ultimate effect of both these furniture forms is stylized. The constructive and decorative issues are combined in a style that is both naïve and refined. The patched up appearance is an upshot of the way that the individual items do not seem to have been held together with either glue or screws, but were mortised on one another and held in 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. Artworks display a kind of chair with a relatively crude wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in between the layers, stitched to produce a pattern of little pads. The front board and a related board at the back could be folded after unscrewing some little iron hooks. Therefore the chair was a portable piece of furniture while traveling which, during the same time, held the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair is seen in engravings of interiors of wealthy Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this type of chair may also be made in countries in which Dutch styles of interior decoration and Dutch furniture won acclaim, it is not decided that the form actually was instigated in The Netherlands. Usually, the legs of the chair will be smooth, round in section, and of slim dimensions; they are occasionally baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was manufactured in considerable quantities, as can be surmised from one of Abraham Bosse’s engravings, in which a whole row of those chairs lined up along a wall. The style asserts itself with its shapely proportions and delicate upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature style—that is to say, as developed in Paris around 1750—spread over most of Europe and has been imitated or copied during the mid-20th century. The chair owes this popularity to a combination of comfort and elegance. 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 on the armrests. Smooth transitions achieved between seat frame, legs, and back disguise all the joints, which are constructed strongly on craftsmanlike practices in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations thereof use wood of fairly thick density; but all the members are deeply molded, all extraneous wood has been removed, and more upmarket designs can be further embellished with special delicate and decorative engraving. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry may be used for all the upholstery on the seat, back, and armrests; cane is in some cases used instead of upholstery.

English chairs of the 18th century were more variable in style than the French. The French manner for stylistic uniformity, which disseminated from the most distinguished circles in Paris and Versailles over 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 reknowned and was widely distributed throughout the world.

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

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

Modern
After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, 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 grants the figures from which accounts are prepared but is a separate process, prior to accounting.

Essentially, bookkeeping finds two kinds of information: (1) the current value, or equity, of the business and (2) the changes in value—profit or loss—taking placement in the enterprise over a given period.

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

Bits and pieces of financial and numerical recordkeeping can be found for almost every state with a commercial background. Records of trade contracts have been uncovered in the archaelogy of Babylon, and accounts for both farms and estates had been made in ancient Greece and Rome. The dual-entry style of bookkeeping began with the development of the commercial republics of Italy, and instruction books for bookkeeping were created in the 15th century in many Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made factual financial bookkeeping a must-have. The past of bookkeeping, in fact, reflects closely the past of commerce, industry, and government and, partially, assisted in shaping it. The international expansion of industrial and commercial activity called for better cosmopolitan decision-making processes, which in its turn needed more sophistication in the selection, classification, and presentation of information, even more so with the aid of computers. Taxation and government regulation became more significant and resulted in greater demand for information; enterprising firms had to have information available to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also become larger, and the requirement for bookkeeping for their inner operations increased.

Though bookkeeping processes can be very detailed, it is all based on two types of books employed in the bookkeeping process—journals and ledgers. A journal should have the daily transactions (sales, purchases, etcetera), and the ledger should have the record of individual accounts. The daily records in the journals are written in the ledgers.

Each month, generally speaking, an income statement and a balance sheet are created from the trial balance posted within the ledger. The duty of the income statement or profit-and-loss statement is to display an analysis of those changes that happen in the entity equity as a result of the operations of the period. The balance sheet provides the financial condition of the corporation at the particular point in time regarding assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

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

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

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

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

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

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

The British ordered a jet-fighter flying-boat, but discovered that this way of doing business without airfields yielded 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.
