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

The typical question customers ask when acquiring a new projector for the home, office, or classroom is: should I take an LCD projector or a DLP projector? LCD, which stands for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many business brands and different types available, it can be difficult for consumers to pick between those technologies. Ultimately LCD projectors have superior image quality and colour accuracy. The next part of this article tells you why DLP projectors struggle with bringing up an equal level of image quality.

Visualise a set of blinds in your room covering your bedroom window. By pulling on a rod you can have the shutters open or closed, depending on whether you want to let light in or not. And such is exactly how an LCD projector works. Each pixel works like its own shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is created of millions of microscopic mirrors or ‘pixel elements’ as the experts like to call them. Each pixel element functions to either reflect light or block it.

How the light source is processed from the point at which the projector turns on to when the image reaches your screen is absolutely important to image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by dividing it into red, blue and green components, by three mirrors which transfer the coloured light to 3 stand alone LCD panels. The 3 LCD panels cast the elements of the image by turning each pixel on and off. The pixels are then projected in a glass prism to send the projector image. Something important to realise about LCD projectors is that all three colours are sent onto your wall at the same time. The way a DLP projector operates is vastly different and even how an image shows up is not the same. With DLP, white light from the lamp is sent through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This way of projecting an image forms a sequence of red, blue and green light. The millions of micro mirrors described above reflect the coloured light on the pixels to form the image elements. The elements of the image are displayed in sequence on the screen, one colour at a time. The viewer’s eye will then combine each coloured element of the image into a complete image. With LCD projectors, all colours are available all the time to offer the best brightness and superb colour accuracy. In DLP, only one colour is available at any given time, resulting in lower colour brightness and accuracy. Some developers have added a white segment into the colour wheel to improve general brightness, but this then damages colour accuracy.

I see in forums all the time that DLP gives a higher contrast ratio and therefore must be better. For those who are 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 offer high contrast specifications when compared to the majority of LCD projectors. Initially, this must be a benefit, 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 duped by contrast specifications on websites and in brochures.

When the content you wish to bring to life requires moving images, DLP projection technology also has image marks, or ‘artifacts’. The most often seen artifact that a DLP projector displays 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 pulled up. LCD projectors do not have this characteristic because the colours are sent with the others. DLP builders have formed 3DLP solutions using 3 chips to fix the colour break up issue, but the price of these projectors make them almost impossible for many businesses and consumers.

Another variance between LCD and DLP is how they compensate for the refractive qualities of light. Think back to high school science, and recall when they taught you how the different colours of light refract varied amounts when projected through the same lens. The downside with DLP projectors is that they utilise 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 in a different way. Usually with a DLP projector, a spill of yellow colour will appear above and an extra blue will be projected below something as simple as a lone black line. In building LCD projectors can be set to reduce these effects on the projected image, as each colour is directed on its own LCD panels.

The isolated actual advantage (excluding price) with picking a DLP projector is its smaller total size and weight. However, this is only relevant for portability and has to be traded off against the image benefits of LCD projectors. If the outcome of the picture quality is important to you, then the solution is simple. Go for an LCD projector! LCD projectors will constantly make bright, colourful images with fewer image blips.

Yachting and Yacht Clubs

As the Dutch came to preeminence in sea power during the 17th century, the first yacht was a leisure craft used first by royalty and secondly by the burghers on the canals and the protected and unprotected waters of the Low Countries. Racing yachts was incidental, arising as 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 presented him with a 20-metre (66-foot) pleasure boat with a beam (maximum width) of 5.6 m (18 feet), which he named Mary. Charles and his brother James, the duke of York (James II, sovereign 1685–88), made additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 wager. Yachting rose as popular among the rich and nobility, but after that time the trend did not last.

The first yacht association in the British Isles, the Water Club, was instigated at about 1720 at Cork, Ire., as a cruising and unofficial coast guard organization, with large naval panoply and rigour. The closest thing to racing was the “chase,” for which the “fleet” pursued a fictional enemy. The club endured, for the large part as a social club, until 1765, and in 1828, after joining with other clubs, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some stipulated method on the Thames around the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV came to monarchy in 1820, it came to be called 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 sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the continuing site of British yacht racing. The society at Cowes became the Royal Yachting Club, likewise 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 bids were held, and the society life was wonderful. Eventually Royal Yachting Club boats increased in size to over 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and went on when the English had power. Sailing was mostly for leisure and found its epitome in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and created a minimum of luxury and sophistication for the later yachts in the area from the late 19th century. The first enduring American yacht association, the Detroit Boat Club, was instigated in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
The first sailing yachts were within the design of such naval craft as brigantines, schooners, and cutters from the 17th century through to the second half of the 19th century. The style of large yachts was originally heavily affected by the victory of America, which was designed by George Steers for a club started 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. Earlier yachts were not designed and crafted in today’s sense, with just a model used. Not until the latter half of the 19th century did what was labeled naval architecture come about. Not until the 1920s did the employment of the science of aerodynamics do for the structure of sails and rigging what science had earlier done for hulls.

Because almost all sailboats had to be individually built, there came a need for handicapping boats as this was previous to the one-design class boats were built. Thus, a rating rule was written, which resulted in the International Rule, adopted in 1906 and edited in 1919. In the present day, one of the fastest blossoming areas in the field of sailing is that of one-design class boats. All boats in a one-design class are built to single specifications in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing such boats can be held on an even par with no handicapping at all. A perfect example is the generic International America’s Cup Class adopted for racers in the 1992 America’s Cup race.

For the time that yachting belonged mostly for the nobility and the rich, money was no object, and the size of boats grew, in both length and weight. The ascendancy and desire of smaller boats occurred in the later half of the 19th century from the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A journey 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 boats. Later in the 20th century, notably 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, craft of less than 3 m were traveled in single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, in which steam began to take the place of sail power in market craft, the steam engine, and later the internal-combustion engine, were increasingly favoured in leisure vessels. Large power yachts were furthered to a high standard, and long-distance travel turned into a favourite activity of the wealthy. The earliest power yachts were paddle-wheel boats; those then gave rise to yachts powered by the wholly submerged screw or propeller kind of propulsion. As well as naval and merchant craft, auxiliaries carrying both sail and power were the yacht standard for several years. By the latter half of the 20th century, many yachts were still auxiliaries, but the larger part were solely power yachts containing gasoline or diesel engines.

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

As larger and more dependable internal-combustion engines were produced, many large yachts began using them for power. The creation of the diesel engine, using heavy oil for fuel, advanced in World War I. In the decade following that, big power-yacht creation blossomed, hitting a climax in the Orion (1930) at 3,097 tons. From that period the biggest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The construction of large power yachts declined in 1932, and the style after that was in preference of smaller, less expensive yachts. Following World War II, a lot of small naval boats were bought by private owners for conversion to yachts. In the late 20th century, yachting is a widespread popular sport enjoyed by thousands of yachtsmen personally manning and upkeeping their own small recreational craft. The number of boats and sailors has increased steadily, not only in the traditional areas by the beach but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be categorized by the impact they have on the placement of income and wealth. A proportional tax is one that impinges the same relative burden on every taxpayer—i.e., where tax liability and income grow in relative proportion. A progressive tax is characterized by a greater than proportional growth in the tax onus relative to the increase in income, and a regressive tax is recognised by a less than proportional increase in the comparable liability. Thus, progressive taxes are thought of as taking away inequity in income distribution, while regressive taxes are found to cause an increase in these inequalities.

The taxes that are normally thought to be progressive include individual income taxes and estate taxes. Income taxes that are categorically progressive, however, could become less so for the upper-income class—particularly if a taxpayer is able to lessen his tax base by nominating deductions or by taking some income elements from his taxable income. Proportional tax rates when applied to lower-income demographics will also be more progressive if such exemptions of a personal nature are claimed.

Income measured over the course of a given period may not definitely provide the most suitable measure of taxpaying status. For example, transitory increases in income can be saved, and in temporary declines in income a taxpayer could select to provide for consumption by decreasing savings. Therefore, if taxation is held in comparison along with “permanent income,” it should be less regressive (or more progressive) than when it is held in comparison with annual income.

Sales taxes and excises (excepting those on luxuries) are usually regressive, because the share of individual income consumed or spent on a specific good declines as the amount of personal income increases. Poll taxes (also known as head taxes), calculated as a flat amount per capita, clearly are regressive.

It is complicated to determine corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to the 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 rests essentially on whether a national or a subnational (that is, provincial or state) tax is being determined.

In considering the economic effects of taxation, it is important to differentiate between various concepts of tax rates. The statutory rates will include those nominated in legislature; generally speaking these are marginal rates, but occasionally they are average rates. Marginal income tax rates indicate the fraction of incremental income demanded by taxation when income grows by one dollar. Ergo, if tax onus rises by 45 cents when income increases by one dollar, the marginal tax rate is 45 percent. Income tax legislation usually contain graduated marginal rates—i.e., rates that rise as income increases. Structured analysis of marginal tax rates must take into account provisions other than the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) decreases by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than indicated by the statutory rates. Since marginal rates specify how after-tax income changes in response to changes in before-tax income, they are the relevant ones for considering incentive effects of taxation. It is even more difficult to understand the marginal effective tax rate applicable to income from business and capital, since it may depend on factors such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem determines that the marginal effective tax rate in income from capital is nothing under a consumption-based tax.

Average income tax rates indicate the portion of total income that is taken 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 rises with income. Average income tax rates usually rise with income, both because personal allowances are provided for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received fundamentally by high-income households could dampen these effects, producing regressivity, as displayed by average tax rates that lessen as income grows.

The Development of Data Projectors

The LCDs put in projection systems are generally small reflective or transmissive panels set off by a bright arc lamp source. A series of lenses magnifies the reflected or transmitted image and casts it on the screen. In front-projection systems the LCD is situated on the side of the screen as the viewer, while in rear-projection systems the screen is set off from behind. Projectors of more expense and capability sometimes have three discrete LCD panels, creating separate red, green, and blue images that come together to form a coloured display on the screen.

The increasing requirement for visual presentations has put a special emphasis on the switching speed of liquid crystals. This has demanded the development of objects utilizing smectic liquid crystals, some types of which have a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most sophisticated smectic device. In it the liquid crystal molecules are cast in layers perpendicular to the substrate planes, which are differentiated by one or two micrometres, and in the layers the molecules are slanted, as demonstrated in the figure. The host liquid crystal possesses optically active molecules, and a minor consequence of the optical activity and the angle 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 through the plane of the layers. Hence, there must be a permanent charge separation over the liquid crystal layer in the SSFLC, and its sign is directly coupled to the tilt direction of the molecules. An applied voltage of the corresponding sign can reverse the direction of this dipole in tens of microseconds and in so doing reverse the tilt direction of the molecules. The resultant change in optical properties can cause a change from light to dark when one or more polarizers are utilised.

SSFLC devices have been commercialized for bigger passive-matrix presentations, but their high cost and complex detail has prevented them from having any remarkable movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have displayed some promise for use as aspects in projection systems or as viewfinders in digital cameras. Their quick reaction allows them to be made use of in time-sequential colour systems, in which dear colour filters are emulated by a coloured backlight that flashes red, green, and blue in rapid pulsing (about 100 cycles a second). For example, the liquid crystal can be switched to a transmissive state between the red and green periods and then to a nontransmissive state for the blue period, having the end result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

From all the furniture pieces, the chair could be paramount. While the majority of other pieces (save for the bed) are created to support objects, the chair supports your human form. The term chair must be regarded here in the general sense, from stool to throne to further makes such as a bench or sofa, which should be viewed as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not clearly distinuishable.

The social history of the chair is as interesting as its history as a creative art. The chair is not just a physical support or an aesthetic creation; it can also be symbolic of social placement. At the past royal courts there were important signifiers between being led to a chair with arms, on a chair with a back but without arms, or worse having to use a stool. Since the last century, a director’s and manager’s chair has been regarded as iconic of superior standing, as well as in democratic governments the speaker sits on an elevated level.

As a furniture purpose, the chair can be utilised for a number of various makes. There are chairs manufactured to suit man’s age and physical abilities (the high chair, the wheelchair) and to denote his status in society (the executive chair, the throne). From the olden days there were chairs used for birth (birth chairs); since the 20th century, there have been chairs used 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. There are chairs that can be folded, chairs on wheels, and chairs on runners.

Modern living has designated unique chairs for use in automobiles and aircraft. Every one of these chair shapes have evolved to fit to changing human requirements. For its significant link with man, the chair exists to its full significance only when being used. While it makes no difference to one’s appreciation of a cupboard or a bureau whether there are items inside or not, a chair is best seen and clearly evaluated with a person using it, for chair and sitter require each other. Thus the several areas of the chair are named according to the limbs of a human form: arms, legs, feet, back, and seat.

Because the basic work of your chair is to support our body, its credit is valued primarily for how well it fulfills this practical purpose. Within the design of a chair, the builder is restricted in the static laws and principal measurements. Inside these boundaries, however, the chair designer has extensive freedom.

The history of the chair covers dates of several thousand years. There is evidence of peoples that have created significant chair shapes, as expressions of the principal craft in the arenas of craft and art. From such civilisations, particular mention must 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 structures of careful craft, are a finding from tombs. First of these two is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair would have had four legs designed like those of a designated animal, a curved seat, leading to a sloping back supported by vertical stretchers. In this design a stable triangular structure was made. There was in our knowledge no notable variation in the design of Egyptian thrones and chairs for regular populace. The real variation was in the level of ornamentation, in the selection of more valuable inlays. The Egyptian folding stool in all likelihood was crafted to be an easily stored seat for soldiers. As a camp stool this form stayed until much later points in time. But the stool also existed in the purpose of a ceremonial seat, its original function as a folding stool neglected or forgotten. This can from evidence be observed, 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 are in the construction of folding stools but cannot be folded because the seats were created of wood. The simplistic make of the folding stool, made of two frames that rotate on metal bolts and bear a seat of leather or fabric held between them, reappeared but somewhat later from the Bronze Age folding chairs of Scandinavia and northern Germany. The better known of those is the folding stool, crafted from ashwood, which is now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is found not with any ancient fossil still existing but as in a variety of pictorial evidence. The best recognised is the klismos depicted on the Hegeso Stele at the Dipylon burial place in outer Athens (c. 410 BC). It is a chair that had a backward-sloping, curved backboard and four curving legs, only two of those legs were shown. These creative legs were thought to have been created in bent wood and were in that case put under great pressure with the weight of the sitter. The joints securing the legs to the frame of the seat had to be therefore super durable and were particularly denoted.

The Romans emulated the Greek designs; a number of casts of seated Romans offer chairs of a denser and in appearance kind of less delicately designed klismos. Both styles, the light and heavy, were revived in the Classicist epoch. The klismos influence can be found in French Empire styles, in English Regency, and in some special types of considerable iconicism of Denmark and Sweden around 1800.

China
The past of the chair in China isn’t able to be traced as far as in Egypt and Greece. Since the Tang dynasty (AD 618–907) an unscathed series of images and artworks was preserved, displaying the insides and exterior of Chinese buildings and their furniture. Another preservation of the 16th century are a number of chairs made from wood or lacquered wood, that show an amazing familiarity to representations of ancient chairs.

As were the designs in Egypt, there were two iconic chair forms in China: a chair with four legs and a folding stool. That chair is constructed both with or without arms although never missing the square seat and straight stiles (straight side supports) to firm the back. In one type, it must be said, the stiles were marginally curved by the arms so as to fit the structure of the S-shaped back splat (the centre upright of the back). Together, the three limbs were mortised into the yoke-like top rail. While the style of the Chinese back splat later had an introduction for English chairs of the Queen Anne period, wooden sections that could merely to a limited extent stabilise corner joints (and are loose as well) signify a feature solely to Chinese chairs. The four legs pass through the seat frame, which closes about the rounded staves. All the members are round in section or has rounded edges—an acknowledgement perchance to the bamboo tradition. The seat is not comfortable and might have had a plaited bottom. These chairs demanded of the sitter to be stiff and upright; for if too much pressure is forced on the back, the chair has a habit of falling over. In patriarchal Chinese houses of this era armchairs most likely were allowed only for the senior people in the family, for they were given great respect.

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 and Scandinavian folding stools, but it has a difference in that the top rail is elegantly joined to the two legs of the stool by means of a curved member, which is usually provided with metal mounts. From a Western understanding the resultant effect of both of these furniture designs is stylized. The structure and decoration parts are combined in a style that is simultaneously naïve and refined. The patchwork appearance is an upshot of the manner that the individual items do not seem to have been joined together with either glue or screws, but have been mortised onto one another and fixed in position in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain during the 17th century also had its mark on the chair. Paintings project a kind of chair with a relatively crude wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in the layers, stitched to bring up a pattern of small pads. The front board and a similar board in the back could be folded after loosening some small iron hooks. Therefore the chair was a portable piece of furniture for traveling which, at the same period, gave the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is found in engravings of interiors of affluent Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this kind of chair may also be found in countries where Dutch styles of interior decoration and Dutch furniture won critical acclaim, it is not believed that the style actually was instigated in The Netherlands. Generally, the legs of the chair are smooth, round in section, and of slim measurements; they are sometimes baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was produced in impressive quantities, as evidenced from one of Abraham Bosse’s engravings, in which a whole row of those chairs lined up along a wall. The design asserts itself by virtue of its elegant proportions and fine 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 created in Paris around 1750—disseminated through most of Europe and has been imitated or copied in the mid-20th century. The model owes the popularity to a combination of leisure and delicacy. The seat suits to the human body and grants a relaxed sitting position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are small upholstered pads covering the armrests. Smooth transitions are achieved between seat frame, legs, and back disguise all the joints, which are constructed strongly on craftsmanlike methods in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of those employ wood of relatively thick dimensions; but each member is deeply molded, all extraneous wood has been taken away, and finer items would be further embellished with intricately delicate and decorative engravings. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry may be used for any upholstery on the seat, back, and armrests; canework is in some cases used rather than upholstery.

English chairs in the 18th century were more varied in style than the French. The French preference for stylistic uniformity, which disseminated from the premier circles in Paris and Versailles throughout most of France and became the preference in several 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
During 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 recording of the money values of the operation of a business. Bookkeeping creates the figures from which accounts are written but is a separate process, required prior to accounting.

Basically, bookkeeping grants two parts of information: (1) the current value, or equity, of the business and (2) the change in value—profit or loss—taking placement in the entity within a singular time period.

Management officials, investors, and credit grantors all need this kind of information: management so as to assess the results of operations, to control costs, to budget for the future, and to make financial policy decisions; investors in order to assess the outcome of business operations and make decisions about buying, holding, and selling securities; and credit grantors in order to regard the financial statements of an entity in assessing whether to grant a loan.

Evidence of financial and numerical charts have been uncovered for almost every civilization with a commercial history. Records of trade contracts were found in the ruins of Babylon, and accounts for both farms and estates were archived in ancient Greece and Rome. The double-entry style of bookkeeping came with the furthering of the enterprising republics of Italy, and instruction books for bookkeeping were developed in the 15th century in several Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made factual financial recordkeeping a necessity. The ancestry of bookkeeping, in fact, reflects closely the history of commerce, industry, and government and, in part, assisted in shaping it. The global spread of industrial and commercial activity required more sophisticated decision-making methodology, which then required better sophistication in the selection, classification, and presentation of information, even more so with the assistance of computers. Taxation and government regulation became more important and resulted in increased requirement for information; businesses had to have available information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also become larger, and the demand for bookkeeping for their inner departmental operations increased.

Although bookkeeping methodology can be extremely multifaceted, all are 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 should have the records of individual accounts. The daily records in the journals are written in the ledgers.

Each month, as a general rule, an income statement and a balance sheet are created from the trial balance posted in the ledger. The job of the income statement or profit-and-loss statement is to present an analysis of the changes that happen in the ownership equity from the transactions of the period. The balance sheet displays the financial situation of the business at the particular date derived 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.
