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

The common question heard when acquiring a new projector for the home, office, or classroom is: will I purchase an LCD projector or a DLP projector? LCD, an acronym 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 different models available, it can be challenging for clients to make a decision between the two technologies. The fact is that LCD projectors give far superior image quality and colour accuracy. The next part of this article will tell you why DLP projectors struggle with reproducing the same grade of image quality.

Visualise a set of blinds in your household over your bedroom window. By twisting a rod you can make the shutters open or closed, according to whether you want to let light in or not. That is exactly how an LCD projector behaves. Each pixel operates like a single shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as professionals 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 switches on to when the image reaches your screen is vitally important with 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 direct 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 simultaneously processed in a glass prism to create the projector image. A significant point to know about LCD projectors is that all three colours are projected onto your screen all at the same time. The way a DLP projector functions is vastly different and even the produced image shows up is not the same. With DLP, white light from the lamp is directed through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of projecting an image casts a sequence of red, blue and green light. The millions of micro mirrors mentioned above reflect the coloured light on the pixels to construct 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 pull together each coloured element of the image into a single full image. Using LCD projectors, all colours are available all the time to form top brightness and fantastic colour accuracy. In DLP, only one colour is available at a time, and so causing lower colour brightness and accuracy. Some manufacturers have placed a white segment in the colour wheel to improve brightness overall, but this also damages colour accuracy.

I see in forums all the time that DLP offers a higher contrast ratio and as such must be superior. For those who are unaware, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the projector is capable of producing. DLP projectors do provide high contrast specifications when compared to most LCD projectors. At a glance, this seems to be a plus, however, in truth, the true black level is determined by the ambient light in the room while the projector is used. Do not be fooled by contrast specifications on websites and in brochures.

When the content you plan to view needs moving images, DLP projection technology also creates image imperfections, or ‘artifacts’. The most common artifact that a DLP projector creates with moving images is colour break up. Colour break up is inherent in DLP systems because moving images change up between the time red, blue and green colours are displayed. LCD projectors do not have this problem because every colour is projected at the same time. DLP designers have created 3DLP solutions using 3 chips to fix the colour break up problem, but the cost of these projectors make them hardly practical for the majority of businesses and consumers.

Another difference between LCD and DLP is how they make up for the refractive qualities of light. Jump back to high school science, and recall when 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 have 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. Often with a DLP projector, some extra yellow colour will show above and a spill of blue will appear below an image as simple as a lone black line. In manufacturing LCD projectors can be adjusted to reduce these effects on the projected image, as each colour is projected on isolated LCD panels.

The one true buy point (excluding price) with choosing a DLP projector is its smaller total size and weight. However, this is only relevant in regard to portability and needs to be traded off against the image advantages of LCD projectors. If resulting picture quality is important to you, then the answer is simple. Go for an LCD projector! LCD projectors will definitely create 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 was a pleasure craft used mostly 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, arising as private matches. English yachting started with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English throne 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 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 returning, on a £100 bet. Yachting became classy for the affluent and royalty, but after that time the fashion 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 gravity. The closest thing to racing was the “chase,” in which the “fleet” pursued an imaginary enemy. The club persisted, mostly as a social club, until 1765, and in 1828, by conglomerating with other groups, it became known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some stipulated fashion 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 with a racing fight, 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 funding made the Solent – the strait between the mainland and the Isle of Wight – the perpetual site of British yachting. The association at Cowes became the Royal Yachting Club, again at the ascension of George IV. Every member was required to own boats of at least 20 tons (20,321 kg). Sailing matches for large bids were held, and the club life was wonderful. Ultimately Royal Yachting Club boats were raised 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 gained control. Sailing was for the most part for pleasure and rose to its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and established a standard of luxury and elegance for the later yachts in those waters from the late 19th century. The first continuing American yacht association, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens founded the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts took the design of such naval craft as brigantines, schooners, and cutters from the 17th century until the latter half of the 19th century. The craft of sizeable yachts was first largely put upon by the win of America, which was drawn by George Steers for a syndicate 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 today’s sense, with merely a model for an outline. Not until the latter half of the 19th century did what was labeled naval architecture come into action. Not until the 1920s did the employment of the research of aerodynamics do for the structure of sails and rigging what it had already done for hulls.

Because almost all sailboats were individually custom-built, there came a desire for handicapping boats previous to the one-design class boats were designed. Thus, a rating rule came into being, which resulted in the International Rule, accepted in 1906 and edited in 1919. In modern times, one of the most rapidly blossoming areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to the same requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing for these boats can be done on an even playing field with no handicapping at all. A prime example is the standard International America’s Cup Class taken on for participants in the 1992 America’s Cup race.

So long as yachting was an activity primarily for the nobility and the rich, cost was no object, and the size of boats developed, in both length and weight. The rise and preference of smaller boats occurred in the later 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) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the value of less sizeable yachts. Later in the 20th century, for the larger part after World War II, smaller racing and leisure yachts became commonplace, down to the dinghy, a favoured training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, when steam began to take the place of sail power in market craft, the steam engine, and later the internal-combustion engine, were favoured increasingly in personal craft. Bigger power yachts were progressed to a high standard, and long-distance sailing was a preferred activity of the affluent. The earliest power yachts were paddle-wheel boats; they then made way to those powered by the completely submerged screw or propeller type of propulsion. As well as naval and merchant yachts, auxiliaries possessing both sail and power were the yacht standard for a number of years. By the second half of the 20th century, several yachts were still auxiliaries, but the majority were exclusively power yachts containing gasoline or diesel engines.

In the last decade of the 19th century there was a boom in the manufacture of more sizeable steam yachts. In particular among these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of over 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 was used in active service for World War II.

As more sizeable and better quality internal-combustion engines were created, many big yachts began using them for power. The establishment of the diesel engine, using heavy oil for fuel, was furthered for World War I. During the decade that followed, bigger power-yacht building grew, hitting a climax in the Orion (1930) at 3,097 tons. During that point the best auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of larger power yachts declined after 1932, and the style thereafter was in preference of smaller, less costly craft. From World War II, a lot of small naval craft were traded by private owners for conversion to yachts. At the late 20th century, yachting has become a widespread popular sport enjoyed by thousands of yachtsmen who are actually owning and keeping their own small leisure yachts. The popularity of yachts and owners 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 differentiated by the effect they have on the allocation of income and wealth. A proportional tax is a kind that imposes the same relative burden on all taxpayers—i.e., when tax liability and income increase in equal levels. A progressive tax is characterized by a higher than proportional rise in the tax liability in regard to the growth in income, and a regressive tax is recognisable by a less than proportional growth in the comparative onus. Ergo, progressive taxes are regarded as reducing inequity in income distribution, but regressive taxes can result in increasing these inequalities.

The taxes that are normally regarded as progressive include individual income taxes and estate taxes. Income taxes that are declarably progressive, however, could become less so for the upper-income group—particularly if a taxpayer is permitted to reduce his tax base by declaring deductions or by taking particular income parts from his taxable income. Proportional tax rates if applied to lower-income demographics could also be more progressive if personal exemptions are declared.

Income measured over the period of a given year may not necessarily give the most accurate measure of taxpaying requirements. For example, transitory increases in income could be saved, and in temporary declines in income a taxpayer may elect to finance consumption by reducing savings. Ergo, if taxation is held in comparison alongside “permanent income,” it would be less regressive (or more progressive) than when it is compared with annual income.

Sales taxes and excises (except luxuries) tend to be regressive, because the share of one’s income consumed or spent for specific goods declines as the rate of personal income grows. Poll taxes (also called head taxes), calculated as a flat amount per capita, patently are regressive.

It is not simple to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to a lack of certainty around 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 crucially on whether a national or a subnational (that is, provincial or state) tax is being debated.

In analysing the economic purpose of taxation, it is necessary to distinguish between several points of tax rates. The statutory rates will include those dictated in legislature; generally these are marginal rates, but for some cases they are average rates. Marginal income tax rates note the fraction of incremental income demanded by taxation when income increases by one dollar. So, if tax liability rises by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax legislature usually contain graduated marginal rates—i.e., rates that increase as income rises. Careful analysis of marginal tax rates are required to review 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 higher than nominated within the statutory rates. Since marginal rates specify how after-tax income is changed in response to changes in before-tax income, they are the important ones for assessing incentive effects of taxation. It is even more complicated to realise the marginal effective tax rate applicable to income from business and capital, because it may rely on factors such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem shows that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates indicate the portion of total income that is required in taxation. The pattern of average rates is the one that is important 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 grow with income, both because personal allowances are allowed for the taxpayer and dependents and because marginal tax rates are graduated; on the flip side, preferential treatment of income received mostly by high-income households may dampen these effects, forcing regressivity, as indicated by average tax rates that decrease as income rises.

The Development of Data Projectors

The LCDs put in projection systems are most often small reflective or transmissive panels lit up by a powerful arc lamp source. A number of lenses enlarges the reflected or transmitted image then sends it onto the screen. With front-projection systems the LCD is set on the same side of the screen as the viewer, however in rear-projection systems the screen is lit up from behind. Projectors of higher expense and capability can be found with three separate LCD panels, creating separate red, green, and blue images that blend to create a coloured picture on the screen.

The increasing demand for pictographic presentations has had a particular emphasis on the switching speed of liquid crystals. This has required the invention of items utilizing smectic liquid crystals, certain types of which emit a faster 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 cast in layers that are perpendicular to the substrate planes, which are differentiated by one or two micrometres, and throughout the layers the molecules are on a slant, as illustrated in the figure. The host liquid crystal possesses optically active molecules, and a subtle consequence of the optical activity and the tilt of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, analogous 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. So, 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 respective change in optical properties can cause a change from light to dark if one or more polarizers are utilised.

SSFLC devices have been publicized for large passive-matrix displays, but their expensiveness and complex nature has impeded them from enjoying any great impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some promise for use as elements in projection systems or as viewfinders in digital cameras. Their fast responding allows them to be used in time-sequential colour systems, in which expensive colour filters are emulated with a coloured backlight that flashes red, green, and blue in fast succession (approximately 100 cycles every second). For example, the liquid crystal may be switched to a transmissive state in the red and green periods but to a nontransmissive state for the blue period, with the end result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Of all furniture items, the chair could be the paramount one. While most other pieces (apart from the bed) are meant to support objects, the chair supports our human form. The term chair must be viewed here in the wider sense, from stool to throne to further types like a bench or sofa, which should be seen as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly defined.

The social history of the chair is as intriguing as its history as an art and craft. The chair is not simply a physical support or an aesthetic item; it can also be a symbol of social place. From the past royal courts there were important signifiers between sitting on a chair with arms, on a chair with a back but no arms, and having to cope with a stool. Since the 20th century, the director’s or manager’s chair has been a symbol of superior status, and even in democratic governments the speaker sits on an elevated platform.

As its furniture form, the chair can be used for a number of different forms. There are chairs manufactured to fit man’s age and physical capabilities (the high chair, the wheelchair) and to connotate his status in society (the executive chair, the throne). During the olden days there were chairs for births (birth chairs); during the 20th century, there have been chairs to die in (the electric chair). We make chairs with one, two, three, and four legs, chairs with or without arms, and chairs with or without backs. We have chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Our modern lifestyle has developed particular chairs for automobiles and aircraft. All of these chair kinds has been changed to suit to growing human needs. Due to its close connection with man, the chair comes to its full purpose only when being used. While it isn’t relevant to one’s appreciation of a cupboard or a chest of drawers whether there might be items inside or not, a chair is really seen best and tested with a person utilising it, for chair and sitter suit each other. Thus the individual elements of the chair were labeled like the names of our human form: arms, legs, feet, back, and seat.

Because the basic role of the chair is to support a human body, its value is valued generally from how fully it does fulfill this practical role. Within the structure of the chair, the chair maker is limited with some static laws and principal measurements. Inside these restrictions, however, the chair builder has marvellous freedom.

The history of the chair is an era of several thousand years. There is evidence of societies that held distinctive chair forms, expressions of the topmost work in the areas of handling and design. Within such cultures, 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 lifetimes of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the upshot of skilled craft, are now seen from tomb findings. One of the two is a four-legged chair with a back, the other a folding stool. The typical Egyptian chair would have had four legs formed not unlike those of some animal, a curved seat, and with a sloping back supported by vertical stretchers. In this design a solid triangular form was obtained. There appeared to be no noteworthy variation from the construction of Egyptian thrones and chairs for typical populace. The only difference existed in the decorative ornamentation, in the choice of more expensive inlays. The Egyptian folding stool most likely was created to be an easily packed seat for soldiers. As a camp stool the stool persevered during much later times. But the stool then was made as the task of a ceremonial seat, its technical task as a folding stool simply forgotten. This can from today be noted, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were constructed in the structure of folding stools but are not able to be folded as the seats are worked from wood. The plain build of the folding stool, consisting of two frames that spin on metal bolts and hold a seat of leather or fabric set between them, reappears but somewhat later in the Bronze Age folding chairs of Scandinavia and northern Germany. The better known of this form is the folding stool, crafted out of ashwood, which is now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is seen not in any ancient object still existing but in a wealth of pictorial evidence. The iconic kind is the klismos posited on the Hegeso Stele at the Dipylon burial place just out of Athens (c. 410 BC). It is a chair with a backward-sloping, curved backboard and four curving legs, but only two of those can be shown. These unusual legs were presumably crafted out of bent wood and were probably needed to bear huge pressure under the weight of the sitter. The joints securing the legs to the frame of the seat are therefore extremely stable and were clearly signified.

The Romans embued the Greek style; existing casts of seated Romans display evidence of a denser and which appear to be a somewhat crudely constructed klismos. Both types, the light and the heavy, were revived in the Classicist period. The klismos chair is known in French Empire design, in English Regency, and in particular kinds of notable iconicism around Denmark and Sweden during 1800.

China
The progression of the chair in China can not be followed as well as the ancestry of the chair in Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) a full folio of images and artworks was kept safe, with images of the interiors and outside of Chinese homes and the furniture. Preserved also since the 16th century are a trove of chairs crafted of wood or lacquered wood, that hold an intriguing similarity to pictures of ancient chairs.

Just the same as in Egypt, there existed two iconic chair forms in China: a chair of four legs and a folding stool. This four-legged chair was constructed both with and without arms but never missing the square seat and straight stiles (upright side supports) to give support to the back. In one kind, though, the stiles had been slightly curved by the arms in order to conform to the angle of the S-shaped back splat (the main upright of a back). Together, all three limbs had been mortised onto the yoke-like top rail. Despite that the innovation of a back splat had an influence on English chairs in the Queen Anne period, wooden members that merely to a restricted ability support corner joints (and furthermore are loose as well) represent a feature signatory to Chinese chairs. The four legs pass through the seat frame, which ends over the rounded staves. Each member is round in section or has rounded edges—referable perchance to the bamboo tradition. The seat is uncomfortable and may have a plaited bottom. These chairs required of the sitter to stay stiff and upright; for if too much pressure is forced on the back, the chair has a habit of toppling over. In patriarchal Chinese houses of this epoch armchairs presumably were kept only for older members of the family, for they were held in great esteem.

The Chinese folding stool is believed to have come to China from the West. It does not differ much from the Egyptian and Scandinavian folding stools, but it possesses a dissimilarity in that the top rail is delicately held to the two legs of the stool in a curved member, which is more often than not provided with metal mounts. From a Western understanding the resulting effect of both these furniture designs is stylized. The constructive and decoration aspects are combined in a way that is all at once naïve and refined. The piecemeal appearance is an outcome of the manner that the individual items do not seem to have been constructed with either glue or screws, but are mortised with one another and held in place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also put its name on the chair. Artworks display a type of chair with a relatively brusque wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing between, stitched to bring out a pattern of tiny pads. The front board and a similar board at the back could be folded after unscrewing some small iron hooks. Thus the chair was a portable piece of furniture while traveling which, in the same time, granted the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is evidenced in engravings of interiors of affluent Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this kind of chair might also be made in countries in which Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not decided that the innovation actually was instigated in The Netherlands. Generally, the legs of the chair are smooth, round in section, and of slender shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was produced in considerable amounts, as surmisable from one of Abraham Bosse’s engravings, in which a whole row of this kind of chairs lined up against a wall. The design asserts itself by its shapely proportions and expensive upholstery in gilt leather or fabric framed with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that was, to say, as progressed in Paris around 1750—spread through most of Europe and was imitated or copied during the mid-20th century. The model owes this popularity to a combination of comfort and charm. The seat suits to the human body and grants a relaxed seated position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are tiny upholstered pads over the armrests. Smooth transitions are found between seat frame, legs, and back conceal all the joints, which are strongly constructed on craftsmanlike methodology even with the absence of stretchers between the legs.

French Rococo chairs and imitations of those are constructed from wood of rather thick dimensions; but all the members are deeply molded, all extraneous wood has been cut away, and more upmarket designs might be further embellished with very delicate and decorative engravings. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for all upholstery on the seat, back, and armrests; cane is occasionally used rather than upholstery.

English chairs in the 18th century were more differentiated in design than the French. The French preference for stylistic uniformity, which came from the premier circles in Paris and Versailles throughout most of France and was popularised 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 commonly known 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, purport 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 transactions of a business. Bookkeeping creates the information from which accounts are written but is a distinct process, preliminary to accounting.

Basically, bookkeeping records 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 enterprise over a singular period of time.

Management officials, investors, and credit grantors all need to have this information: management so as to analyse the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to assess the outcome of business operations and make decisions regarding buying, holding, and selling securities; and credit grantors to judge the financial statements of a business in judging whether to grant a loan.

Traces of financial and numerical recordkeeping have been found for just about every society with a commercial history. Records of trading contracts were discovered in the remains of Babylon, and accounts for both farms and estates had been kept in ancient Greece and Rome. The two-entry manner of bookkeeping came with the furthering of the enterprising republics of Italy, and instruction manuals for bookkeeping were created within the 15th century in many Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made factual financial records a paramount factor. The ancestry of bookkeeping, in fact, closely reflects the history of commerce, industry, and government and, partially, assisted shaping it. The global expansion of industrial and commercial activity required greater sophisticate decision-making procedures, which then demanded greater sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government regulation became more significant and resulted in increased need for information; entities had to have information available 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 departmental operations went up.

Although bookkeeping processes can be rather multifaceted, it is all based on two types of books utilised in the bookkeeping process—journals and ledgers. A journal should have the daily transactions (sales, purchases, and so on), and the ledger must have the details of individual accounts. The daily records in the journals are entered in the ledgers.

At the end of every month, by general practice, an income statement and a balance sheet are created from the trial balance posted in the ledger. The point of the income statement or profit-and-loss statement is to display an analysis of those changes that have taken place in the business equity as a result of the events of the period. The balance sheet provides the financial position of the company at the particular point in time 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 trend to get back to the ‘eyeball-to-eyeball’ type of confrontation of the man in the Sopwith Camel. The pre-eminent Western fighter, the McDonnell Douglas F-4 Phantom, was rebuilt with an internal gun, a rapid-fire 20 mm (0.79 in) cannon with six barrels firing up to 6,000 rds/ min, and a slatted wing to pull tighter turns in combat.

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

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

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