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

The most common question heard when purchasing a new projector for the home, office, or classroom is: will I buy an LCD projector or a DLP projector? LCD, an acronym for ‘liquid crystal device’ and DLP, short for ‘digital light processing’ are the two most common projector imaging technologies. With so many different brands and models available, it can be confusing for the buyer to make a choice between those technologies. The simple fact of the matter is that LCD projectors offer far better image quality and colour accuracy. The article below explains why DLP projectors struggle with projecting a similar standard of image quality.

Visualise a set of blinds in your home on your bedroom window. By pulling on a rod you can have the shutters open or closed, depending on if you want to let light in or not. And such is exactly how an LCD projector functions. Each pixel functions like an individual shutter on a set of blinds to either allow light through or to block it. DLP on the other hand is constructed 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 point when the projector switches on to when the image reaches your screen is ultimately significant for image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by separating it into red, blue and green components, by three mirrors which project the coloured light to 3 stand alone LCD panels. The 3 LCD panels create the elements of the image by switching each pixel on and off. The pixels are then simultaneously processed in a glass prism to create the projector image. Something to understad about LCD projectors is that all three colours are projected onto your wall at the same time. The way a DLP projector operates is widely different and even how an image appears is not the same. With DLP, white light from the lamp is processed 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 requires a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to create the image elements. The elements of the image are cast in sequence on the screen, one colour at a time. The viewer’s eyes will then put together each coloured element of the image into a whole image. Using LCD projectors, all colours are available all the time to form the top level of brightness and spectacular colour accuracy. In DLP, just one colour is available at any given time, resulting in lower colour brightness and accuracy. Some manufacturers have added a white segment in the colour wheel to improve overall brightness, but this then detracts from colour accuracy.

I read in forums all the time that DLP has a higher contrast ratio and thus must be better quality. For those who do not know, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the technology is capable of. DLP projectors do possess high contrast specifications as compared to many LCD projectors. At a glance, this can seem to be a benefit, however, in the real world, the true black level is determined by the ambient light in the room in which the projector is utilised. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you plan to project needs moving images, DLP projection technology also has image marks, or ‘artifacts’. The most commonplace artifact that a DLP projector forms 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 projected. LCD projectors do not have this problem because all colours are projected at once. DLP developers have developed 3DLP solutions using 3 chips to resolve the colour break up artifacts, but the price tag of these projectors make them almost impossible for many businesses and consumers.

Another differentiation between LCD and DLP is how they make up for the refractive qualities of light. Remember back to high school science, and they taught you how the various colours of light refract various amounts when projected through the same lens. The downfall 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. Generally with a DLP projector, some extra yellow colour will appear above and some blue will show below an image of something as simple as a straight black line. While being built LCD projectors can be adapted to minimize these effects on the projected image, because each colour is directed on separate LCD panels.

The isolated real advantage (excluding price) with picking a DLP projector is its smaller overall size and weight. However, this is only relevant to portability and must be traded off against the image plusses of LCD projectors. If resulting picture quality is important to you, then the solution is easy. Take an LCD projector! LCD projectors will definitely create 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 became a leisure craft used first by royalty and secondly by the burghers for the canals and the protected and unprotected waters of the Low Countries. Yacht racing 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 throne in 1660, the city of Amsterdam presented him with a 20-metre (66-foot) leisure 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 more yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and returning, on a £100 wager. Yachting became fashionable among the rich and royalty, but after that point the habit did not last.

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

Yacht racing began in some ordered method on the Thames around the mid-18th century. The duke of Cumberland founded the Cumberland Fleet for Thames racing in 1775. When George IV rose to the throne in 1820, it came to be known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded after a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht organisation had been started at Cowes on the Isle of Wight in 1815, and royal sponsorship made the Solent – the strait between the mainland and the Isle of Wight – the continued location of British yachting. The club at Cowes became the Royal Yachting Club, likewise at the accession of George IV. All members were required to possess boats of at least 20 tons (20,321 kg). Sailing tests for high bets were held, and the social life was wonderful. Eventually Royal Yachting Club boats increased in size to over 350 tons.

In North America, yachting began with the Dutch in New York in the 17th century and continued when the English took power. Sailing was for the most part for fun and found its high point in George Crowinshield’s Cleopatra’s Barge (1815), which traveled on the Mediterranean Sea and created a standard of luxury and elegance for the later yachts in those waters from the late 19th century. The first persisting American yacht club, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens founded the New York Yacht Club aboard his schooner Gimcrack.

Kinds of sailboats
Early sailing yachts were within the style of such naval craft as brigantines, schooners, and cutters from the 17th century until the second half of the 19th century. The design of large yachts was initially greatly affected by the win of America, which was created by George Steers for a group led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its win at Cowes in 1851. The first yachts were not designed and built in the modern sense, with only a model being used. 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 study of aerodynamics do for the craft of sails and rigging what it had previously done for hulls.

Because nearly all sailboats had been individually manufactured, there was a need for handicapping boats before the one-design class boats were made. Therefore, a rating rule was created, which resulted in the International Rule, accepted in 1906 and amended in 1919. In modern times, one of the rapidly flourishing areas in sailing is that of one-design class boats. All boats in a one-design class are created to the same specifications in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing between such boats can be had on an even keel with no handicapping necessary. A great example is the uniform International America’s Cup Class taken on board for yachts in the 1992 America’s Cup race.

As long as yachting was an activity primarily for the nobility and the affluent, expense was no issue, and the size of boats grew, in both length and weight. The ascendancy and preference of smaller boats happened in the second 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 journey around the world (1895–98) captained single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the hardiness of small craft. Later in the 20th century, for the larger part after World War II, smaller racing and pleasure yachts became more popular, down to the dinghy, a popular training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were setting sail single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, at which point steam started to take the place of sail power in commercial vessels, the steam engine, and later the internal-combustion engine, were employed more and more in leisure yachts. Large power yachts were furthered to a high degree, and long-distance cruising turned into a fond occupation of the well off. The first power yachts were paddle-wheel boats; these then gave rise to those powered by the wholly submerged screw or propeller kind of propulsion. Like naval and merchant craft, auxiliaries carrying both sail and power were the yacht standard for several years. By the second half of the 20th century, many yachts were still auxiliaries, but the large part were only power yachts with gasoline or diesel engines.

From the last decade of the 19th century there was a push in the construction of large steam yachts. In particular of these was the Mayflower (1897) of 2,690 tons, that had triple-expansion engines, twin screws, and a compartmented iron hull, and was manned by a crew of more than 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 was used in active service for World War II.

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

The building of larger power craft lessened after 1932, and the style thereafter was for smaller, less expensive craft. After World War II, many small naval vessels were sold to private owners for conversion to yachts. By the late 20th century, yachting is a globally loved activity enjoyed by thousands of yachtsmen personally manning and keeping their own small recreational craft. The number of craft and owners 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 are differentiated by the effect they have on the distribution of income and wealth. A proportional tax is one that imposes the same relative requirement on all the taxpayers—i.e., where tax liability and income increase in the same levels. A progressive tax is characterizable by a larger than proportional increase in the tax liability in relation to the increase in income, and a regressive tax is characterized by a less than proportional increase in the related burden. So, progressive taxes are seen as taking away inequalities in income distribution, whereas regressive taxes are believed to have the result of increasing these inequalities.

The taxes that are normally considered progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, might become less so for the upper-income demographic—particularly if a taxpayer is permitted to reduce his tax base by nominating deductions or by taking particular income elements from his taxable income. Proportional tax rates if applied to lower-income categories will also be more progressive if exemptions of a personal nature are claimed.

Income measured over the period of a given year does not necessarily come up with the most accurate measure of taxpaying requirements. For example, transitory rises in income may be saved, and within temporary declines in income a taxpayer may choose to pay for consumption by taking from savings. Therefore, if taxation is compared with “permanent income,” it will be less regressive (or more progressive) than if held in comparison with annual income.

Sales taxes and excises (save on luxuries) tend to be regressive, because the portion of individual income consumed or spent on specific goods decreases as the level of personal income is raised. Poll taxes (also known as head taxes), nominated as a flat amount per capita, obviously are regressive.

It is complicated to term corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of uncertainty surrounding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden rests essentially on whether a national or a subnational (that is, provincial or state) tax is being debated.

In assessing the economic effects of taxation, it is important to differentiate between differing concepts of tax rates. The statutory rates are nominated in the legislation; often these are marginal rates, but sometimes they are average rates. Marginal income tax rates denote the fraction of incremental income demanded by taxation when income rises by one dollar. So, if tax onus increases by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax legislature often contain graduated marginal rates—i.e., rates that grow as income rises. Structured analysis of marginal tax rates should take into account provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) reduces by 20 cents for each one-dollar growth in income, the marginal rate is 20 percentage points higher than nominated by the statutory rates. Since marginal rates specify how after-tax income increases or decreases in response to changes in before-tax income, they are the relevant ones for appraising incentive effects of taxation. It is even more difficult to know the marginal effective tax rate applicable to income from business and capital, as it may depend on considerations including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem shows that the marginal effective tax rate in income from capital is nothing under a consumption-based tax.

Average income tax rates display the part of total income that is paid 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 commonly rise with income, both because personal allowances are provided for the taxpayer and dependents and because marginal tax rates are graduated; on the other hand, preferential treatment of income received predominantly by high-income households can dampen these effects, forcing regressivity, as shown by average tax rates that lower as income rises.

The Development of Data Projectors

The LCDs put in projection systems are typically small reflective or transmissive panels lit up by a powerful arc lamp source. A number of lenses magnifies the reflected or transmitted image then casts it on the screen. In front-projection systems the LCD is placed on the side of the screen as the viewer, but in rear-projection systems the screen is lit up from behind. Projectors of greater cost and capability might use three discrete LCD panels, reflecting separate red, green, and blue images that come together to form a coloured picture on the screen.

The growth in desire for video displays has put a growing emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of items employing smectic liquid crystals, some types of which emit a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most progressive smectic device. With it the liquid crystal molecules are cast in layers that are perpendicular to the substrate planes, which are separated by one or two micrometres, and inside the layers the molecules are on a tilt, as displayed in the figure. The host liquid crystal has optically active molecules, and a subtle outcome of the optical activity and the shape of the molecules is the presence of a permanent charge separation, or ferroelectric dipole, likeable to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and in the plane of the layers. So, there must be a permanent charge separation across 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 correct sign can reverse the direction of this dipole in tens of microseconds and so reverse the tilt direction of the molecules. The resultant change in optical properties can cause a change from light to dark if or when one or more polarizers are employed.

SSFLC devices have been produced for large passive-matrix presentations, but their expensiveness and complex nature has prevented them from making any particular movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, have shown some probability for use as parts in projection systems or as viewfinders in digital cameras. Their quick response allows them to be employed in time-sequential colour systems, in which dear colour filters are removed for a coloured backlight that flashes red, green, and blue in quick pulsing (approx 100 cycles every second). For example, the liquid crystal may be switched to a transmissive state during the red and green periods and then to a nontransmissive state during the blue period, displaying the result that the eye sees an average of red and green light, or the colour yellow.

The History of the Chair

Out of each of the furniture items, the chair may be the imperative one. While the majority of other pieces (save for the bed) are meant to support objects, the chair supports a human form. The term chair is meant to be looked upon here in the general sense, from stool to throne to complex chairs like the bench and 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 labeled.

The social history of the chair is as curious as its history as art and craft. The chair is not just a physical support and/or aesthetic item; it is historically an indicator of social standing. Within the historical royal courts there were plain distinctions between having a chair with arms, or a chair with a back but without arms, or having to squat on a stool. During the past century, the director’s and/or manager’s chair has been a symbol of superior rank, and in democratic parliaments the speaker sits on a raised level.

As a furniture creation, the chair encompasses a range of different models. There are chairs manufactured to suit man’s age and physical abilities (the high chair, the wheelchair) and to show his standing in society (the executive chair, the throne). From the olden days there were chairs to be born in (birth chairs); during the 20th century, there have been chairs used to die in (the electric chair). There are chairs with one, two, three, and/or four legs, chairs with or without arms, and chairs with or without backs. We make chairs that can be folded for easy storage, chairs on wheels, and chairs on runners.

Our modern lifestyle has developed unique chairs in automobiles and aircraft. Every one of these chair shapes has been adapted to match to growing human uses. For its significant connection with man, the chair comes to its full significance only when being utilised. Though it does not make a difference to one’s appreciation of a cupboard or a dresser drawers whether there is anything inside or not, a chair is understood best and evaluated with a person utilising it, for chair and sitter require each other. Thus the various parts of the chair are labeled according to the limbs of a human body: arms, legs, feet, back, and seat.

Because the simple job of a chair is to support a body, its credit is valued basically on how fully it does measure up to this practical purpose. In the creation of the chair, the maker is restricted under certain static regulations and principal measurements. In these limitations, however, the chair builder has awesome freedom.

The history of the chair lasts over a period of several thousand years. There is evidence of cultures that created distinctive chair shapes, seen of the premier object in the spheres of handling and art. Among such societies, particular mention should 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 items of skilled make, are now a finding from discoveries made in tombs. One of these two is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair had four legs crafted like those of a chosen animal, a curved seat, and leading to a sloping back supported by vertical stretchers. From this a stable triangular design was created. There seems to be no significant variation between the construction of Egyptian thrones and chairs for typical people. The real change was in the decorative ornamentation, in the selection of more expensive inlays. The Egyptian folding stool probably was designed for an easily portable seat for army. As a camp stool this kind stayed til much later periods of time. But the stool also existed in the purpose of a ceremonial seat, its mechanical job as a folding stool being forgotten. This can today be noted, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They were made in the construction of folding stools but are not able to be folded as the seats are made out of wood. The simplistic make of the folding stool, consisting of two frames that rotate on metal bolts and bear a seat of leather or fabric set between them, then came up some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The better recognised of this kind is the folding stool, crafted from ashwood, which is now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is found not in any ancient specimen still around but as found in a trove of pictorial evidence. The better known is the klismos depicted on the Hegeso Stele at the Dipylon burial ground in outer Athens (c. 410 BC). This klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of them were visible. These unusual legs were understood to have been created from bent wood and were therefore had extreme pressure from the weight of the sitter. The joints fastening the legs to the frame of the seat would have been therefore very durable and were particularly drawn.

The Romans embued the Greek designs; quite a few models of seated Romans show evidence of a thicker and apparently somewhat crudely crafted klismos. Both designs, the light and the heavy, were brought back in the Classicist period. The klismos chair can be evidenced in French Empire design, in English Regency, and in some types of notable originality within Denmark and Sweden from 1800.

China
The ancestry of the chair in China isn’t able to be followed as well as chairs in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an unbroken series of drawings and artworks had been protected, detailing the interiors and exterior of Chinese homes and the designs of furniture. Another preservation of the 16th century are a collection of chairs of wood or lacquered wood, that hold an intriguing likeness to styles of ancient chairs.

Just the same as in Egypt, there existed two standard chair designs in China: a chair that had four legs and a folding stool. This four-legged chair can be found both with and without arms though never missing a square seat and straight stiles (vertical side supports) to hold up the back. In one kind, however, the stiles could be marginally curved on top of the arms to conform correctly to the structure of the S-shaped back splat (the basic upright of a back). Each of the three limbs were mortised in the yoke-like top rail. Although the design of the Chinese back splat exercised an inspiration for English chairs from the Queen Anne period, wooden members that merely to a limited limit reinforce corner joints (and were loose in the bargain) indicate a design particular to Chinese chairs. The four legs sit through the seat frame, which finishes over the rounded staves. All the members are round in section or is given rounded edges—references as may be to the bamboo tradition. The seat is uncomfortable and occasionally had a plaited texture. These chairs required of the sitter to stay stiff and upright; for if too much weight is forced on the back, the chair has a way of collapsing. In patriarchal Chinese homes of this period armchairs likely were allowed only for elderly members of the family, for they were greatly respected.

The Chinese folding stool is understood to have come to China from the West. It does not vary that much from the Egyptian or Scandinavian folding stools, but it possesses a variation in that the top rail is prettily joined to the two legs of the stool in a curved member, which is often designed with metal mounts. From a Western understanding the resulting effect of these furniture styles is stylized. The construction and aesthetic issues are combined in a way that is all at once both naïve and refined. The patched up appearance is an upshot of the manner that the individual parts do not look to have been affixed by either glue or screws, but have been mortised with one another and locked into place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also left its mark on the chair. Paintings project a design of chair with a relatively crude 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 little pads. The front board and a related board from the back could be folded after loosening some tiny iron hooks. Thus the chair was a readily portable piece of furniture in traveling which, during the same time, granted the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered design of chair can be found in engravings of the interior of wealthy Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this style 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 started in The Netherlands. Generally, the legs of the chair were smooth, round in section, and of slim dimensions; they are sometimes baluster-shaped (vase-shaped) or twisted. It is clearly a bourgeois piece of furniture and was produced in vast quantities, as surmisable from one of Abraham Bosse’s engravings, in which there is an entire row of these chairs lined up against a wall. The design asserts itself with its harmonious 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 form—that was, to say, as created in Paris around 1750—conquered most of Europe and has been imitated or copied in the mid-20th century. The chair owes such popularity to a combination of relaxation and delicacy. The seat suits to the human body and permits a relaxed sitting position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are little upholstered pads over the armrests. Smooth transitions achieved between seat frame, legs, and back conceal all the joints, which are constructed on craftsmanlike methods even with the absence of stretchers between the legs.

French Rococo chairs and imitations of them are made from wood of fairly thick measurements; but every member is deeply molded, all extra wood has been cut away, and more expensive items might be further embellished with very delicate and decorative engraving. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry is usually used for all upholstery on the seat, back, and armrests; canework is occasionally used rather than upholstery.

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

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

Essentially, bookkeeping finds two areas of information: (1) the current value, or equity, of the enterprise and (2) changes in value—profit or loss—taking place in the entity from a singular period of time.

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

Evidence of financial and numerical charts can be uncovered for just about every civilization with a commercial history. Records of commercial contracts have been uncovered in the remains of Babylon, and accounts for both farms and estates were archived in ancient Greece and Rome. The dual-entry way of bookkeeping came up with the furthering of the entrepeneurial republics of Italy, and instruction manuals for bookkeeping were produced within the 15th century in several Italian cities.

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

The development of manufacturing, trading, shipping, and subsidiary services made perfect financial recordkeeping a requirement. The past of bookkeeping, in fact, resembles the past of commerce, industry, and government and, in some part, assisted to form it. The worldwide expansion of industrial and commercial activity needed higher professional decision-making methodology, which itself required greater sophistication in the selection, classification, and presentation of information, even more so with the aid of computers. Taxation and government regulation became more detailed and resulted in greater requirement for information; business entities had to provide information to bolster their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also developed in size, and the requirement for bookkeeping for departmental operations went up.

While bookkeeping processes can be very multifaceted, all of it is based on two types of books used in the bookkeeping procedure—journals and ledgers. A journal has the daily transactions (sales, purchases, and so on), and the ledger contains the information of individual accounts. The daily records from the journals are put in the ledgers.

Every month, as a general rule, an income statement and a balance sheet are made from the trial balance posted out of the ledger. The job of the income statement or profit-and-loss statement is to show an analysis of the changes that have occurred in the business equity resulting from the operations of the period. The balance sheet gives the financial position of the business at any particular day 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 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 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.
