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 take an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, which stands for ‘digital light processing’ are the two most common projector imaging technologies. With so many brands and models available, it can be confusing for clients to make a decision between the two technologies. It comes down to the fact that LCD projectors have better image quality and colour accuracy. The following article will explain why DLP projectors struggle with creating an equal level of image quality.

It’s like a set of blinds in your house covering your bedroom window. With the twist of a rod you can make the shutters open or closed, depending on if you want to let light in or not. And this is exactly how an LCD projector functions. Each pixel operates like a single shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is constructed of millions of microscopic mirrors or ‘pixel elements’ as pros 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 turned on to when the picture reaches your screen is ultimately significant for image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by splitting it into red, blue and green components, by three mirrors which direct 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 simultaneously processed in a glass prism to form the projector image. A point to remember about LCD projectors is that all three colours are projected onto your wall all at the same time. The way a DLP projector runs is vastly different and even the way an image appears is not the same. With DLP, white light from the lamp is directed through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of forming 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 sent in sequence on the screen, one colour at a time. The viewer’s eye will then put together each coloured element of the image into the full image. With LCD projectors, all colours are available all the time to create the highest brightness and superb colour accuracy. In DLP, just one colour is available at any given time, and so causing lower colour brightness and accuracy. Some DLP developers have included a white segment in the colour wheel to improve brightness overall, but this goes and damages colour accuracy.

I hear in forums all the time that DLP has a higher contrast ratio and as such must be superior 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 projector is capable of producing. DLP projectors do offer high contrast specifications in comparison to many LCD projectors. At first glance, this appears to be an advantage, however, in reality, the true black level is determined by the ambient light in the room in which the projector is used. Do not be duped by contrast specifications on websites and in brochures.

When the content you want to project needs moving images, DLP projection technology also has image errors, or ‘artifacts’. The most commonplace artifact that a DLP projector shows 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 displayed. LCD projectors do not have this characteristic because the colours are delivered at once. DLP builders have come up with 3DLP solutions using 3 chips to answer the colour break up issue, but the price of these projectors make them hardly practical for the majority of businesses and consumers.

Another differentiation between LCD and DLP is how they make up for the refractive qualities of light. Think back to high school science, and remember how various colours of light refract various amounts when projected through the same lens. The downside with DLP projectors is that they use the one same panel and the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light at different levels. Usually with a DLP projector, some extra yellow colour will appear above and a spill of blue will come up below an image as simple as a lone black line. While being built LCD projectors can be adjusted to remove these effects on the projected image, as each colour is refracted on isolated LCD panels.

The only real buy point (excluding price) with picking a DLP projector is its smaller size and weight. However, this is only relevant to transport and must be traded off against the image plusses of LCD projectors. If resulting picture quality is crucial to you, then the decision is simple. Go with an LCD projector! LCD projectors will consistently produce bright, colourful images with fewer image imperfections.

Yachting and Yacht Clubs

As the Dutch rose to preeminence in sea power during the 17th century, the first yacht became a leisure 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. Racing yachts was incidental, arising as private games. English yachting originated with King Charles II of England during his exile in the Low Countries. On his return to the English royalty in 1660, the city of Amsterdam sent him a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he then named Mary. Charles and his brother James, the duke of York (James II, reigned 1685–88), built additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 bet. Yachting was found to be popular for the wealthy and royalty, but after that period the fashion did not last.

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

Yacht racing was seen in some organized method on the Thames about the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV came to the throne in 1820, it was then known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing argument, to become the Royal Thames Yacht Club in 1830. The first English yacht group had been initiated at Cowes on the Isle of Wight in 1815, and royal patronage made the Solent – the strait between the mainland and the Isle of Wight – the perpetual site of British yachting. The society at Cowes became the Royal Yachting Club, also at the rise of George IV. Every member was required to possess boats of at least 20 tons (20,321 kg). Sailing races for high bets were held, and the social life was lovely. It came to be that the Royal Yachting Club boats increased in size to more than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and went on when the English gained control. Sailing was for the most part for leisure and reached its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and set a standard of luxury and elegance for the later yachts in those waters from the late 19th century. The first persisting 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
The Early sailing yachts took the design of such naval craft as brigantines, schooners, and cutters from the 17th century until the later half of the 19th century. The style of sizeable yachts was initially largely put upon by the success of America, which was drawn by George Steers for a group started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) had its namesake after its success at Cowes in 1851. The first yachts were not designed and crafted in a contemporary sense, with merely a model used. Not until the later half of the 19th century did what was labeled naval architecture come into being. Not until the 1920s did the employment of the science of aerodynamics do for the craft of sails and rigging what such science had done earlier for hulls.

Because nearly all sailboats had been individually custom-built, there was a desire for handicapping boats before the one-design class boats were made. Thus, a rating rule came into being, which resulted in the International Rule, adopted in 1906 and amended in 1919. In the present day, one of the fastest flourishing areas in sailing is that of one-design class boats. All boats in a one-design class are built to single requirements in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between these boats can be done on an even playing field with no handicapping necessary. A prime example is the standard International America’s Cup Class taken on 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 object, and the size of boats increased, in both length and weight. The rise and desire of smaller boats occurred in the latter 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 voyage around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray demonstrated the hardiness of less sizeable boats. Thereafter in the 20th century, notably after World War II, smaller racing and recreational boats became commonplace, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
Following the decade 1840–50, during which steam started to take the place of sail power in commercial boats, the steam engine, and later the internal-combustion engine, were increasingly used in pleasure boats. Bigger power yachts were developed to a high standard, and long-distance travel became a fond pastime of the affluent. The first power yachts were paddle-wheel boats; those then gave rise to boats powered by the wholly submerged screw or propeller type of propulsion. As in the case of naval and merchant vessels, auxiliaries possessing both sail and power were the yacht fashion for several years. By the second half of the 20th century, many yachts were still auxiliaries, but the majority were only power yachts that had gasoline or diesel engines.

During the last decade of the 19th century there was a push in the design of more sizeable steam yachts. In particular among 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 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 during World War II.

As bigger and better quality internal-combustion engines were developed, many bigger boats were using them for power. The establishment of the diesel engine, employing heavy oil for fuel, advanced for World War I. During the decade following that, bigger power-yacht building grew, climaxing in the Orion (1930) at 3,097 tons. During that period the largest auxiliary yacht built was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of bigger power craft fell away after 1932, and the fashion from then was toward smaller, less pricey boats. After World War II, many small naval vessels were sold to private owners for conversion to yachts. At the late 20th century, yachting is a widespread loved sport enjoyed by thousands of yachtsmen who are actually sailing and upkeeping their own small leisure yachts. The popularity of boats and yachtsmen is increasing steadily, not only in the traditional locations along the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be distinguished by the effect they have on the placement of income and wealth. A proportional tax is a kind that impinges the same relative liability on all taxpayers—i.e., when tax liability and income move in relative scale. A progressive tax is recognised by a greater than proportional growth in the tax liability relative to the growth in income, and a regressive tax is characterizable by a less than proportional rise in the related onus. Thus, progressive taxes are viewed as removing the lack of equality in income distribution, while regressive taxes might result in an increase these inequalities.

The taxes that are often regarded as progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, might become less so within the upper-income class—particularly if a taxpayer is allowed to lower his tax base by nominating deductions or by removing some certain income components from his taxable income. Proportional tax rates that are applied to lower-income groups can also be more progressive if such exemptions of a personal nature are made.

Income measured over the course of a given period may not necessarily give the most appropriate measure of taxpaying requirement. For example, transitory rises in income may be saved, and in temporary declines in income a taxpayer may choose to pay for consumption by decreasing savings. Therefore, if taxation is made comparable along with “permanent income,” it would be less regressive (or more progressive) than when made comparable with annual income.

Sales taxes and excises (save on luxuries) are mostly regressive, because the dissemination of personal income consumed or spent on specific goods lessens as the rate of personal income rises. Poll taxes (also termed head taxes), calculated as a set amount per capita, obviously are regressive.

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

In considering the economic effects of taxation, it is important to distinguish between differing points of tax rates. The statutory rates will be specified in the law; generally these are marginal rates, but for some cases they are average rates. Marginal income tax rates note the fraction of incremental income that is demanded by taxation when income grows by one dollar. Ergo, if tax liability grows by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax statutes often contain graduated marginal rates—i.e., rates that increase as income increases. Heavy analysis of marginal tax rates need to take into account provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) falls by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points higher than specified in the statutory rates. Since marginal rates signify how after-tax income changes in response to changes in before-tax income, they are the relevant 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, because it may rely on considerations such 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 part of total income that is demanded in taxation. The pattern of average rates is the one that is important for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates usually rise with income, both because personal allowances are allowed for the taxpayer and dependents and also due to that marginal tax rates are graduated; on the other side of things, preferential treatment of income received predominantly by high-income households may swamp these effects, producing regressivity, as displayed by average tax rates that lessen as income rises.

The Development of Data Projectors

The LCDs built for projection systems are usually small reflective or transmissive panels illuminated by a forceful arc lamp source. A line of lenses expands the reflected or transmitted image then casts it onto the screen. With front-projection systems the LCD is set on the same area of the screen as the viewer, however in rear-projection systems the screen is set off from behind. Projectors of more expense and performance might use three distinct LCD panels, forming separate red, green, and blue images that come together to reflect a coloured display on the screen.

The growing desire for film displays has granted a particular emphasis on the switching speed of liquid crystals. This has demanded the invention of objects utilizing smectic liquid crystals, some types of which give a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most progressive smectic device. Inside it the liquid crystal molecules are managed in layers that are perpendicular to the substrate planes, which are distanced by one or two micrometres, and in the layers the molecules are tilted, as shown in the figure. The host liquid crystal possesses optically active molecules, and a subtle result of the optical activity and the slant of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, comparable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and in the plane of the layers. Thus, there must be a permanent charge separation over 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 correct sign can reverse the direction of this dipole in tens of microseconds and hence reverse the tilt direction of the molecules. The consequential change in optical properties can cause a change from light to dark if one or more polarizers are used.

SSFLC devices have been produced for big passive-matrix displays, but their high cost and complexity has stopped them from making any great impact on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some promise for use as aspects in projection systems or as viewfinders in digital cameras. Their immediate response allows them to be used in time-sequential colour systems, in which high cost colour filters are emulated by a coloured backlight that flashes red, green, and blue in fast speed (about 100 cycles every second). For example, the liquid crystal might be switched to a transmissive state between the red and green periods and to a nontransmissive state during the blue period, having the upshot that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From each of the furniture items, the chair may be the primary one. While most other objects (save the bed) are created to support objects, the chair supports your human form. The term chair was looked upon here in the general sense, from stool to throne to further makes including the bench or sofa, which might be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not evidently labeled.

The social history of the chair is as exciting as its history as an art and craft. The chair is not simply a physical support or aesthetic piece of art; it historically is symbolic of social ranking. At the historical royal courts there were important differences between possessing a chair with arms, sitting on a chair with a back but no arms, or worse having to utilise a stool. In the recent century, a director’s and manager’s chair has risen an indicator of superior rank, and in democratic governments the speaker sits on a high-set floor.

As a furniture construction, the chair encompasses a range of different purposes. There are chairs manufactured to match man’s age and physical capabilities (the high chair, the wheelchair) and to show his position in society (the executive chair, the throne). In past days there were chairs to be born in (birth chairs); during the 20th century, there have been chairs to die in (the electric chair). We have chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Our lifestyle has designated unique chairs for use in automobiles and aircraft. Every one of these chair types have evolved to fit to changing human needs. From its close importance with man, the chair comes to its full advantage only when being used. Although it isn’t relevant to one’s appreciation of a cupboard or a bureau whether there is anything inside or not, a chair is really understood and fairly evaluated by a person utilising it, for chair and sitter suit the other. Thus the various areas of the chair have been named like the parts of the human form: arms, legs, feet, back, and seat.

Because the simple job of a chair is to support your body, its worth is tested generally by how completely it fulfills this practical job. Within the creation of a chair, the carpenter is limited within the static law and principal measurements. Within these rules, however, the chair builder has great freedom.

The history of the chair lasts over a period of several thousand years. There are cultures that had made iconic chair types, seen of the leading craft in the arenas of craft and art. From those peoples, a mention 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 objects of expert scheme, were found from findings made in tombs. First of these is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair would have had four legs structured as akin to those of an animal, a curved seat, and a sloping back supported by vertical stretchers. In this way a stable triangular design was made. There was from our knowledge no particular difference in the structure of Egyptian thrones and chairs for ordinary populace. The only difference existed in the intricacy of its ornamentation, in the particulars of expensive inlays. The Egyptian folding stool in all probability was crafted as an easily carried seat for army soldiers. As a camp stool the form existed til much later times. But the stool then also was made for the purpose of a ceremonial seat, its original history as a folding stool being forgotten. This can already be noted, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They are in the form of folding stools but can not be folded because the seats are formed of wood. The simple construction of the folding stool, being of two frames that cycle on metal bolts and support a seat of leather or fabric set between them, came up some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognisable of this type is the folding stool, crafted from ashwood, which is now at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is recognised not as any ancient item still existing but as seen in a wealth of pictorial items. The most well known is the klismos displayed on the Hegeso Stele at the Dipylon burial location in outer Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of these legs would be seen. These strange legs were likely to have been manufactured out of bent wood and were therefore had a large amount of pressure from the weight of the sitter. The joints securing the legs to the frame of the seat are therefore extremely solid and were overtly indicated.

The Romans adopted the Greek design; existing models of seated Romans display examples of a thicker and apparently somewhat more crudely designed klismos. Both styles, the light and heavy, were brought back during the Classicist period. The klismos chair is known in French Empire styles, in English Regency, and in some particular brands of profound uniqueness in Denmark and Sweden during 1800.

China
The progression of the chair in China can not be followed as far as the history of chairs in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unbroken folio of sketches and artworks had been kept safe, detailing the interiors and exteriors of Chinese houses and the kinds of furniture. Kept also of the 16th century are a trove of chairs made of wood or lacquered wood, that hold an intriguing likeness to representations of past chairs.

Same as in Egypt, there was two major chair designs in China: a chair that had four legs and a folding stool. That four-legged chair was constructed both with or without arms but always with a square seat and straight stiles (vertical side supports) to hold up the back. In one design, it has been seen, the stiles were delicately curved by the arms in order to fit the shape of the S-shaped back splat (the main upright of a chairback). Each of the three parts had been mortised on the yoke-like top rail. Despite that the style of this back splat exercised an inspiration for English chairs from the Queen Anne period, wooden members that would only to a limited capability support corner joints (as well as being loose to top it off) are a feature particular to Chinese chairs. The four legs are set through the seat frame, which ends over the rounded staves. All the members are round in section or has rounded edges—referable perhaps to the bamboo tradition. The seat is not pleasant and occasionally had a plaited texture. These chairs needed the sitter to remain stiff and upright; for if too much weight is exerted on the back, the chair has a tendency to topple. In patriarchal Chinese homes of this era armchairs presumably were reserved only for elderly family members, for they were given great esteem.

The Chinese folding stool is believed to have travelled to China from the West. It does not differ very much from the Egyptian and Scandinavian folding stools, but it possesses a dissimilarity in that the top rail is elegantly affixed to the two legs of the stool in a curved member, which is more often than not provided with metal mounts. From a Western viewpoint the ultimate effect of both these furniture forms is stylized. The manufacture and aesthetic aspects are combined in a style that is at the same time naïve and refined. The pieced-together appearance is an outcome of the manner that the individual parts do not appear to have been fixed with either glue or screws, but are mortised into one another and fixed in place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also left its signature on the chair. Artworks project a style of chair with a relatively brusque wooden frame; a back and seat, nailed on, having only two layers of leather, with horsehair stuffing in between the layers, stitched to bring up a pattern of tiny pads. The front board and a related board in the back could be folded after loosening some tiny iron hooks. In this way the chair was an easily portable piece of furniture in traveling which, at 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 the interior of rich Dutch homes by Abraham Bosse, a French artist, and in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this design of chair might also be found in countries in which Dutch styles of interior decoration and Dutch furniture won acclaim, it is not believed that the style actually began in The Netherlands. Typically, the legs of the chair will be smooth, round in section, and of thin measurements; they are in some cases baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was made in large numbers, as can be surmised from one of Abraham Bosse’s engravings, in which a whole row of such chairs lined up along a wall. The style asserts itself by virtue of its shapely proportions and expensive upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that was, as developed in Paris around 1750—conquered most of Europe and has been imitated or copied in the mid-20th century. The style owes its popularity to a combination of comfort and delicacy. The seat suits to the human body and allows a relaxed seated position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are little upholstered pads covering the armrests. Smooth transitions made between seat frame, legs, and back cover all the joints, which are stable, constructed on craftsmanlike methods even with the absence of stretchers between the legs.

French Rococo chairs and imitations of those have wood of relatively thick dimensions; but all members are deeply molded, all extra wood has been taken away, and more upmarket examples would be further embellished with very delicate and decorative engraving. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry can be used for any upholstery on the seat, back, and armrests; crosshatched cane is occasionally used instead of upholstery.

English chairs of the 18th century were more differentiated in design than the French. The French preference for stylistic uniformity, which came from the most distinguished circles in Paris and Versailles through most of France and became the preference 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 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 products 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 recordkeeping of the money values of the operation of a business. Bookkeeping grants the figures from which accounts are written but is a distinct process, preliminary to accounting.

Essentially, bookkeeping provides two types of information: (1) the current value, or equity, of the business and (2) any changes in value—profit or loss—taking placement in the enterprise within a singular period.

Management officials, investors, and credit grantors all need this kind of information: management in order to interpret the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to analyse the outcome of business operations and make decisions for buying, holding, and selling securities; and credit grantors to analyze the financial statements of an enterprise in finding whether to allow a loan.

Traces of financial and numerical record charts have been found for almost every society with a commercial background. Records of trading contracts have been uncovered in the remains of Babylon, and accounts for both farms and estates have been held in ancient Greece and Rome. The dual-entry process of bookkeeping started with the furthering of the commercial republics of Italy, and tutorial manuals for bookkeeping were produced in the 15th century in some Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made accurate financial books a paramount factor. The ancestry of bookkeeping, in fact, reflects closely the history of commerce, industry, and government and, in some part, assisted to form it. The worldwide revolution of industrial and commercial activity called for more professional decision-making processes, which in turn needed greater sophistication in the selection, classification, and presentation of information, even more so with the progression of computers. Taxation and government legislation became more significant and resulted in greater demand for information; entities had to provide information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew, and the requirement for bookkeeping for their own inner departmental operations went up.

Though bookkeeping methods can be extremely multifaceted, all of it is based on two types of books utilised in the bookkeeping process—journals and ledgers. A journal has the daily transactions (sales, purchases, and so on), and the ledger must have the information of individual accounts. The daily records in the journals are put in the ledgers.

Each month, by general practice, an income statement and a balance sheet are created from the trial balance posted from the ledger. The duty of the income statement or profit-and-loss statement is to provide an analysis of the changes that took place in the business equity from the events of the period. The balance sheet gives the financial situation of the enterprise at the particular date taken from assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

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

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

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

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

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

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

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