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

The most common question asked when acquiring a new projector for the home, office, or classroom is: would I get an LCD projector or a DLP projector? LCD, short for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two most common projector imaging technologies. With so many business brands and models available, it can be challenging for clients to pick between both technologies. The fact is that LCD projectors provide far superior image quality and colour accuracy. The article below will explain why DLP projectors struggle with creating a comparable grade of image quality.

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

How the light source is processed from the time the projector is switched on to when the content reaches your screen is ultimately significant with regard to image quality, brightness and colour accuracy. LCD projectors direct white light from the lamp by separating it into red, blue and green components, by three mirrors which transfer the coloured light to 3 different LCD panels. The 3 LCD panels create the elements of the image by turning each pixel on and off. The pixels are then simultaneously processed in a glass prism to form the projector image. An important point to realise about LCD projectors is that all three colours are delivered onto your wall all at the same time. The way a DLP projector operates is totally different and even the produced image looks is not the same. With DLP, white light from the lamp is projected through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of creating an image creates a sequence of red, blue and green light. The millions of micro mirrors as described above reflect the coloured light on the pixels to produce the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s vision will then combine each coloured element of the image into the total image. Using LCD projectors, all colours are available all the time to create high brightness and spectacular colour accuracy. In DLP, just one colour is available at a time, and so causing lower colour brightness and accuracy. Some designers have put a white segment for the colour wheel to improve overall brightness, but this also lessens colour accuracy.

I find in forums all the time that DLP has a higher contrast ratio and ergo must be better quality. For those unsure, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the machine is capable of producing. DLP projectors do provide high contrast specifications when compared to a majority of LCD projectors. At a glance, this must be an advantage, however, in the real world, the true black level is determined by the ambient light in the room when the projector is used. Do not be tricked by contrast specifications on websites and in brochures.

When the content you wish to see needs moving images, DLP projection technology can also have image errors, or ‘artifacts’. The most commonplace artifact that a DLP projector creates with moving images is colour break up. Colour break up is to be expected in DLP systems because moving images change position between the time red, blue and green colours are projected. LCD projectors do not have this characteristic because all the colours are delivered at once. DLP developers have come up with 3DLP solutions using 3 chips to resolve the colour break up error, but the price of these projectors make them almost impossible for many businesses and consumers.

Another differentiation between LCD and DLP is how they balance for the refractive qualities of light. Jump back to high school science, and they taught you how different colours of light refract varied amounts when projected through the same lens. The problem 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 not the same and refract light in a different way. Most of the time with a DLP projector, some extra yellow colour will come up above and a spill of blue will come up below an image as simple as a single black line. In building LCD projectors can be fixed to take away these effects on the projected image, because each colour is directed on separate LCD panels.

The isolated actual buy point (excluding price) with taking a DLP projector is its overall smaller size and weight. However, this is only relevant in regard to transporting the device and must be traded off against the image plusses of LCD projectors. If the result of the picture quality is vital to you, then the decision is no-brainer. Go for an LCD projector! LCD projectors will consistently produce bright, colourful images with fewer image mistakes.

Yachting and Yacht Clubs

As the Dutch rose to dominance in sea power during the 17th century, the early yacht became a leisure craft used initially by royalty and later by the burghers for the canals as well as the protected and unprotected waters of the Low Countries. Yacht racing was incidental, coming out of private matches. English yachting originated with King Charles II of England during his exile in the Low Countries. On his restoration to the English royalty in 1660, the city of Amsterdam sent him a 20-metre (66-foot) leisure 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), built other 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 became classy with the affluent and aristocracy, but after that point the habit did not last.

The first yacht group in the British Isles, the Water Club, was formed in about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and had great naval panoply and formality. The closest thing to a race was the “chase,” when the “fleet” pursued a fictional enemy. The club endured, mostly as a social club, until 1765, and in 1828, when joining with other organisations, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some stipulated method on the Thames around 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 after a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht society 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 continued location of British yacht racing. The society at Cowes became the Royal Yachting Club, again at the accession of George IV. All members were required to own boats of at least 20 tons (20,321 kg). Sailing races for great stakes were held, and the social life was superlative. Eventually Royal Yachting Club boats increased in size to over 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and persisted when the English took dominance. Sailing was mostly for pleasure and found its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and established a minimum of luxury and elegance for the later yachts in the area from the late 19th century. The first continuing American yacht club, the Detroit Boat Club, was started in 1839. In 1844, John C. Stevens began the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts were within the style of such naval craft as brigantines, schooners, and cutters from the 17th century through the later half of the 19th century. The design of large yachts was first largely affected by the success of America, which was designed by George Steers for a association 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 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 use of the study of aerodynamics do for the structure of sails and rigging what such science had previously done for hulls.

Because nearly all sailboats were individually manufactured, there arose a desire for handicapping boats before the one-design class boats were designed. Hence, a rating rule came into being, which is found in the International Rule, adopted in 1906 and amended in 1919. Today, one of the most rapidly growing areas in sailing is that of one-design class boats. All boats in a one-design class are built to standard requirements in length, beam, sail area, and other aspects (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 prime example is the generic International America’s Cup Class taken on board for participants in the 1992 America’s Cup race.

As long as yachting was done largely for the nobility and the wealthy, expense was no problem, and the size of boats developed, in both length and weight. The promotion and popularity of smaller boats 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 voyage 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 small craft. Later in the 20th century, notably after World War II, smaller racing and pleasure boats became more common, down to the dinghy, a popular training boat, of 3.7 m. In the late 20th century, craft 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 market vessels, the steam engine, and later the internal-combustion engine, were employed increasingly in leisure vessels. Sizeable power yachts were developed to a high element, and long-distance travel became a preferred activity of the well off. The early power yachts were paddle-wheel boats; these then gave way to yachts powered by the wholly submerged screw or propeller type of propulsion. As well as naval and merchant yachts, auxiliaries carrying both sail and power were the yacht standard for several years. By the second half of the 20th century, a lot of yachts were still auxiliaries, but the majority were exclusively power yachts with gasoline or diesel engines.

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

As larger and better quality internal-combustion engines were produced, many big yachts started using them for power. The creation of the diesel engine, using heavy oil for fuel, advanced from World War I. During the decade that followed, big power-yacht creation flourished, hitting a climax in the Orion (1930) at 3,097 tons. In that time the largest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of larger power yachts declined in 1932, and the trend thereafter was in preference of smaller, less costly boats. Following World War II, many small naval craft were sold to private owners for conversion to yachts. In the late 20th century, yachting has become a widespread popular activity enjoyed by thousands of yachtsmen individually sailing and keeping their own small recreational boats. The popularity of yachts and sailors 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 can be categorized by the effect they have on the placement of income and wealth. A proportional tax is a tax that puts the same relative burden on all taxpayers—i.e., where tax liability and income move in the same levels. A progressive tax is recognised by a larger than proportional rise in the tax burden in regard to the rise in income, and a regressive tax is characterizable by a less than proportional growth in the comparative liability. Therefore, progressive taxes are regarded as reducing inequalities in income distribution, but regressive taxes can increase these inequalities.

The taxes that are normally considered progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, may become less so in the upper-income group—especially if a taxpayer is able to reduce his tax base by claiming deductions or by removing certain income parts from his taxable income. Proportional tax rates that are applied to lower-income demographics could also be more progressive if personal exemptions are made.

Income measured over the period of a year might not absolutely give the most appropriate measure of taxpaying requirements. For example, transitory increases in income could be saved, and during temporary declines in income a taxpayer may choose to finance consumption by decreasing savings. So, if taxation is regarded alongside “permanent income,” it should be less regressive (or more progressive) than when it is made comparable with annual income.

Sales taxes and excises (except luxuries) are generally regressive, because the share of own income consumed or spent on a specific good lessens as the level of personal income is raised. Poll taxes (also called head taxes), levied as a flat amount per capita, obviously are regressive.

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

In regarding the economic effects of taxation, it is relevant to distinguish between several ideas of tax rates. The statutory rates will be nominated in the legislation; commonly these are marginal rates, but sometimes they are median rates. Marginal income tax rates note the fraction of incremental income demanded by taxation when income rises by one dollar. Hence, if tax onus increases by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax legislature commonly contain graduated marginal rates—i.e., rates that rise as income rises. Careful analysis of marginal tax rates must regard provisions other than the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points more than nominated within the statutory rates. Since marginal rates display how after-tax income is changed in response to changes in before-tax income, they are the appropriate ones for considering incentive effects of taxation. It is even more difficult to know the marginal effective tax rate applicable to income from business and capital, as it may be reliant 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 show the fraction of total income that is taken in taxation. The pattern of average rates is the one that is important for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates usually increase with income, both because personal allowances are provided for the taxpayer and dependents and also because marginal tax rates are graduated; on the other hand, preferential treatment of income received for the most part by high-income households can dwarf these effects, forcing regressivity, as displayed by average tax rates that lessen as income grows.

The Development of Data Projectors

The LCDs built for projection systems are usually small reflective or transmissive panels lit up by a strong arc lamp source. A line of lenses magnifies the reflected or transmitted image and then casts it on the screen. With front-projection systems the LCD is located on the same side of the screen as the viewer, however in rear-projection systems the screen is set off from behind. Projectors of more expense and capacity sometimes have three separated LCD panels, forming separate red, green, and blue images that blend to make a coloured picture on the screen.

The growth in demand for film displays has granted a growth in emphasis on the switching speed of liquid crystals. This has necessitated the invention of objects using smectic liquid crystals, some types 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 sophisticated smectic device. With it the liquid crystal molecules are arranged in perpendicular layers to the substrate planes, which are differentiated by one or two micrometres, and inside the layers the molecules are on a tilt, as illustrated in the figure. The host liquid crystal possesses optically active molecules, and a scarcely perceptible result of the optical activity and the slant 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 through the plane of the layers. Therefore, there exists 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 right sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The consequential change in optical properties can effect 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 displays, but their expense and complex detail has impeded them from having any remarkable progress on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some probability for use as elements in projection systems or as viewfinders in digital cameras. Their quick responding allows them to be made use of in time-sequential colour systems, in which dear colour filters are taken out for a coloured backlight that flashes red, green, and blue in fast pulsing (approx 100 cycles per second). For example, the liquid crystal may be switched to a transmissive state for the red and green periods but then to a nontransmissive state during the blue period, displaying the outcome that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of all furniture forms, the chair could be paramount. While most of the other pieces (apart from the bed) are devised to support objects, the chair supports a human form. The term chair must be used here in the larger sense, from stool to throne to developed kinds like a bench and sofa, which can be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not obviously definitive.

The social history of the chair is as stimulating as its history as a creative craft. The chair is not just a physical support or an aesthetic creation; it historically is symbolic of social status. At the past royal courts there were clear connotations between being seated on a chair with arms, or a chair with a back but without arms, or worse having to squat on a stool. In the last century, a director’s or manager’s chair has become iconic of superior rank, like in democratic parliaments the speaker sits on a raised platform.

In its furniture creation, the chair is employed for a number of various forms. There are chairs manufactured to suit man’s age and physical capabilities (the high chair, the wheelchair) and to connotate his position in society (the executive chair, the throne). During past days there were chairs used for birth (birth chairs); during the 20th century, there have been chairs used for ending life (the electric chair). We design chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We can have chairs that can be folded up, chairs on wheels, and chairs on runners.

Our modern lifestyle has derived particular chairs in automobiles and aircraft. Each of these chair kinds have evolved to suit to growing human requirements. From its close connection with man, the chair comes to its full importance only when being utilised. Whereas it is not relevant to one’s appreciation of a cupboard or a set of drawers whether there is anything inside or not, a chair is understood and fairly regarded by a person using it, for chair and sitter need the other. Thus the various areas of a chair have been given labels as the elements of a human body: arms, legs, feet, back, and seat.

Because the elementary job of a chair is to support your body, its worth is tested firstly on how completely it measures up to this practical purpose. Within the design of the chair, the chair maker is restricted for particular static rules and principal measurements. Within these limitations, however, the chair creator has large freedom.

The history of the chair lasts over dates of several thousand years. There are peoples that held significant chair forms, as expressive of the foremost object in the arenas of handling and aesthetics. In such peoples, 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 ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the result of masterful scheme, were known from tomb discoveries. One of them is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair would have four legs structured as akin to those of a designated animal, a curved seat, and with a sloping back supported from vertical stretchers. In this way a solid triangular design was crafted. There seemed to be no significant differentiation in the construction of Egyptian thrones and chairs for typical non-royals. The main variation exists in the decorative ornamentation, in the particulars of pricier inlays. The Egyptian folding stool most likely was made as an easily portable seat for army. As a camp stool the kind continued until much later days. But the stool then was made as the use of a ceremonial seat, its mechanical task as a folding stool simply forgotten. This can already be seen, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were constructed in the structure of folding stools but can’t be folded as the seats are made from wood. The easy make of the folding stool, composed of two frames that spin on metal bolts and support a seat of leather or fabric secured between them, also appeared but somewhat later as the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognisable of this type is the folding stool, of ashwood, now found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is recognised not in any ancient item still existing but in a large amount of pictorial items. The significant kind is the klismos seen on the Hegeso Stele at the Dipylon burial ground in outer Athens (c. 410 BC). It is a chair with a backward-sloping, curved backboard and four curving legs, only two of them can be seen. These curved legs were most likely to have been manufactured with bent wood and were as such subjected to a large amount of pressure from the weight of the sitter. The joints attaching the legs to the frame of the seat would have been therefore very durable and were clearly indicated.

The Romans embued the Greek designs; quite a few models of seated Romans offer evidence of a denser and which appear to be a somewhat crudely built klismos. Both kinds, the light or the heavy, were popularised during the Classicist time. The klismos design is evidenced in French Empire styles, in English Regency, and in some particular brands of notable originality within Denmark and Sweden during 1800.

China
The past of the chair in China is not able to be traced as far back as the ancestry of the chair in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an unbroken series of drawings and works of art was kept safe, with images of the interiors and exteriors of Chinese houses and the designs of furniture. Kept also from the 16th century are a collection of chairs crafted from wood or lacquered wood, that possess an interesting likeness to images of previous chairs.

As in Egypt, there existed two major chair designs in China: a chair that had four legs and a folding stool. That four-legged chair is designed both with or without arms however never without a square seat and straight stiles (standing side supports) to firm the back. In one kind, it has been found, the stiles could be slightly curved above the arms for the purpose of suit the structure of the S-shaped back splat (the central upright of a chairback). Together, all three limbs are mortised into the yoke-like top rail. Despite that the style of the back splat then had a foundation for English chairs within the Queen Anne period, wooden sections that would merely to a restricted capability embolden corner joints (and furthermore were loose into the bargain) are a feature exclusive to Chinese chairs. The four legs sit through the seat frame, which ends upon the rounded staves. Every member is round in section or has rounded edges—acknowledging perchance to the bamboo tradition. The seat is uncomfortable and occasionally had a plaited seat. These chairs required the sitter to be stiff and upright; when too much weight is placed on the back, the chair has a tendency to fall over. In patriarchal Chinese homes of this era armchairs most likely were kept for senior individuals, for they were held in great esteem.

The Chinese folding stool is presumed to have been brought to China from the West. It does not vary so very much from the Egyptian or Scandinavian folding stools, but it possesses a change in that the top rail is elegantly fixed to the two legs of the stool with a curved member, which is usually possessing metal mounts. From a Western point of view the overall effect of both furniture styles is stylized. The manufacture and decorative aspects are combined in a way that is all at once both naïve and refined. The patchwork appearance is a result of the way that the individual items do not appear to have been put together by means of either glue or screws, but were mortised on one another and held in position in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also left its mark on the chair. Paintings display a kind of chair with a relatively crude wooden frame; a back and seat, nailed on, consisting of two layers of leather, with horsehair stuffing in the layers, stitched to show up a pattern of little pads. The front board and a corresponding board from the back could be folded after loosening some little iron hooks. Thus the chair was a portable piece of furniture when traveling which, in the same era, had the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair is found 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. Though this design of chair is also made in countries in which Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not held that the form actually started in The Netherlands. Normally, the legs of the chair are smooth, round in section, and of slim dimensions; they are sometimes baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was produced in considerable numbers, as surmisable from one of Abraham Bosse’s engravings, in which an entire row of these chairs lined up against a wall. The style asserts itself by virtue of its elegant proportions and fine upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that was, 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 design owes its popularity to a combination of relaxation and delicacy. The seat adheres to the human body and grants a relaxed sitting position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are small upholstered pads over the armrests. Smooth transitions made between seat frame, legs, and back cover all the joints, which are strongly constructed 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 members are deeply molded, all extra wood has been removed, and more expensive items can be further embellished with special delicate and decorative carvings. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for all upholstery on the seat, back, and armrests; crosshatched cane is sometimes used instead of upholstery.

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

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

Essentially, bookkeeping grants two parts of information: (1) the current value, or equity, of the enterprise and (2) the change in value—profit or loss—taking place in the enterprise during a given period.

Management officials, investors, and credit grantors all require such information: management to analyse the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors so as to analyse the upshot of business operations and make decisions about buying, holding, and selling securities; and credit grantors so as to analyze the financial statements of an enterprise in assessing whether to give a loan.

Pieces of financial and numerical charts are uncovered for almost every civilization with a commercial history. Records of commercial contracts were discovered in the archaelogy of Babylon, and accounts for both farms and estates have been archived in ancient Greece and Rome. The dual-entry method of bookkeeping began with the furthering of the commercial republics of Italy, and instruction manuals for bookkeeping were created in the 15th century in various Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made correct financial books a paramount factor. The history of bookkeeping, in fact, closely reflects the past of commerce, industry, and government and, in part, helped shaping it. The global revolution of industrial and commercial activity required greater professional decision-making methods, which in its turn demanded higher sophistication in the selection, classification, and presentation of information, increasingly with the assistance of computers. Taxation and government legislature became more detailed and resulted in greater need 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 become larger, and the demand for bookkeeping for their inner operations went up.

Although bookkeeping procedures can be extremely detailed, it is all based on two types of books utilised in the bookkeeping process—journals and ledgers. A journal contains the daily transactions (sales, purchases, and such), and the ledger must have the record of individual accounts. The daily records kept in the journals are written in the ledgers.

At the end of each month, generally speaking, an income statement and a balance sheet are created from the trial balance posted out of the ledger. The job of the income statement or profit-and-loss statement is to present an analysis of any changes that took place in the enterprise equity resulting from the transactions of the period. The balance sheet provides the financial situation of the company at any 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 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.
