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

The most common question customers ask when acquiring a new projector for the home, office, or classroom is: do I purchase an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, standing for ‘digital light processing’ are the two commonplace projector imaging technologies. With so many business brands and models available, it can be overwhelming for consumers to make a decision between both technologies. The simple fact of the matter is that LCD projectors give far superior image quality and colour accuracy. The article below will tell you why DLP projectors struggle with projecting the same grade of image quality.

Visualise a set of blinds in your house on your bedroom window. By twisting a rod you can make the shutters open or closed, according to whether you want to let light in or not. That is exactly how an LCD projector 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 created of millions of microscopic mirrors or ‘pixel elements’ as the experts like to call them. Each pixel element operates to either reflect light or block it.

How the light source is processed from the time the projector is turned on to when the content reaches your screen is absolutely important for image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by splitting it into red, blue and green components, by three mirrors which transfer the coloured light to 3 individual LCD panels. The 3 LCD panels form the elements of the image by switching each pixel on and off. The pixels are then combined in a glass prism to create the projector image. A significant point to remember about LCD projectors is that all three colours are projected onto your projector screen all at once. The way a DLP projector works is very different and even the way an image appears is not the same. With DLP, white light from the lamp is processed through a rotating colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This approach to forming an image casts a sequence of red, blue and green light. The millions of micro mirrors 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 vision will then combine each coloured element of the image into the single whole image. Using LCD projectors, all colours are available all the time to form the best brightness and great colour accuracy. In DLP, just one colour is available at a time, causing lower colour brightness and accuracy. Some DLP designers have put a white segment into the colour wheel to improve brightness overall, but this then damages colour accuracy.

I read in forums all the time that DLP gives a higher contrast ratio and ergo must be better. For those who don’t 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 offer high contrast specifications when compared to a majority of LCD projectors. Initially, this can seem to be a benefit, however, in truth, the true black level is determined by the ambient light in the room in which the projector is utilised. Do not be duped by contrast specifications on websites and in brochures.

When the content you want to view has moving images, DLP projection technology also creates image marks, or ‘artifacts’. The most typical artifact that a DLP projector creates with moving images is colour break up. Colour break up is unavoidable in DLP systems because moving images keep changing between the time red, blue and green colours are shone. LCD projectors do not have this downside because all the colours are processed at once. DLP designers have come up with 3DLP solutions using 3 chips to solve the colour break up artifacts, but the price of these projectors make them almost impossible for many businesses and consumers.

Another differentiation between LCD and DLP is how they match the balance for the refractive qualities of light. Take yourself back to high school science, and remember when they taught you how various colours of light refract various amounts when passing through the same lens. The downfall with DLP projectors is that they take the one same panel for the same lens to project Red, Blue and Green. All 3 colours are obviously not the same and refract light differently. Usually with a DLP projector, some yellow colour will show above and a spill of blue will show below an image containing something as simple as a straight black line. While being built LCD projectors can be fixed to minimize these effects on the projected image, as each colour is processed on its own LCD panels.

The sole actual plus (excluding price) with deciding on a DLP projector is its overall smaller size and weight. However, this is only relevant in regard to transport and has to be traded off against the image benefits of LCD projectors. If the result of the picture quality is crucial to you, then the answer is easy. Take an LCD projector! LCD projectors will consistently produce bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch rose to dominance in sea power during the 17th century, the early yacht became a pleasure craft used mostly by royalty and secondly by the burghers in the canals as well as the protected and unprotected waters of the Low Countries. Racing yachts was incidental, coming out of private challenges. English yachting began with King Charles II of England during his exile in the Low Countries. On his reaffirmation to the English throne in 1660, the city of Amsterdam presented him with 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, sovereign 1685–88), ordered for additional yachts and in 1662 raced two of them from the Thames, from Greenwich, to Gravesend, and back, on a £100 wager. Yachting rose as popular with the wealthy and nobility, but after that point the habit did not last.

The first yacht group in the British Isles, the Water Club, was started in about 1720 at Cork, Ire., as a cruising and unofficial coast guard group, and held much naval panoply and formality. The closest thing to racing boats was the “chase,” when the “fleet” pursued a fictional enemy. The club went on, mostly as a social club, until 1765, and in 1828, by joining with other clubs, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some organized fashion on the Thames in the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV rose to sovereignty in 1820, it was known as the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht club 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 continuing setting of British yacht racing. The organisation at Cowes became the Royal Yachting Club, likewise at the rise of George IV. Each member was required to own boats of at least 20 tons (20,321 kg). Sailing matches for high bets were held, and the society life was wonderful. Eventually Royal Yachting Club boats grew in size to over 350 tons.

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

Kinds of sailboats
The first sailing yachts were within the lines of such naval craft as brigantines, schooners, and cutters from the 17th century until the later half of the 19th century. The craft of large yachts was first largely affected by the victory of America, which was created 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 win at Cowes in 1851. Earlier yachts were not designed and manufactured in today’s sense, with only a model used. Not until the later half of the 19th century did what was called naval architecture come about. Not until the 1920s did the use of the science of aerodynamics do for the structure of sails and rigging what it had earlier done for hulls.

Because almost all sailboats had been individually manufactured, there was a desire for handicapping boats as this was before the one-design class boats were made. Therefore, a rating rule came into being, which ended up in the International Rule, taken on in 1906 and revised in 1919. Today, one of the rapidly blossoming areas in the field of sailing is that of one-design class boats. All boats in a one-design class are created to the same dimensions in length, beam, sail area, and other elements (for an example of a two-person sailboat, see illustration). Racing for those boats can be done on an even basis with no handicapping required. A prime example is the generic International America’s Cup Class taken on for participants in the 1992 America’s Cup race.

So long as yachting was an activity primarily for the aristocracy and the rich, money was no problem, and the size of boats grew, in both length and weight. The ascendancy and desire of smaller craft happened in the latter 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) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the hardiness of smaller craft. Later in the 20th century, notably after World War II, smaller racing and recreational boats became more popular, down to the dinghy, a favoured 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
Post the decade 1840–50, when steam was set to take the place of sail power in commercial boats, the steam engine, and later the internal-combustion engine, were employed more and more in personal boats. Large power yachts were progressed to a high standard, and long-distance travel turned into a favoured pastime of the wealthy. The first power yachts were paddle-wheel boats; those then made way to yachts powered by the wholly submerged screw or propeller kind of propulsion. As well as naval and merchant vessels, auxiliaries possessing both sail and power were the yacht standard for several years. By the latter half of the 20th century, a lot of yachts were still auxiliaries, but the majority were exclusively power yachts containing gasoline or diesel engines.

During the last decade of the 19th century there was a push in the design of bigger steam yachts. Notably within 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, commissioned by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and gave active service in World War II.

As more sizeable and more reliable internal-combustion engines were developed, many bigger boats were using them for power. The development of the diesel engine, with heavy oil for fuel, progressed from World War I. From the decade following that, bigger power-yacht building grew, climaxing in the Orion (1930) at 3,097 tons. In that period the biggest auxiliary yacht constructed was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of larger power boats fell away from 1932, and the style thereafter was in preference of smaller, less costly yachts. Following World War II, a lot of small naval boats were traded by private owners for conversion to yachts. By the late 20th century, yachting is a widespread beloved sport enjoyed by thousands of yachtsmen individually manning and upkeeping their own small leisure craft. The amount of yachts and owners increased steadily, not only in the traditional places along the sea but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes can be categorized by the effect they have on the distribution of income and wealth. A proportional tax is the kind that puts the same relative burden on each taxpayer—i.e., when tax liability and income increase in the same scale. A progressive tax is recognisable by a more than proportional growth in the tax liability in regard to the rise in income, and a regressive tax is recognisable by a less than proportional increase in the relative onus. So, progressive taxes are viewed as fighting inequalities in income distribution, while regressive taxes might have the result of increasing these inequalities.

The taxes that are often believed to be progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, can become less so within the upper-income demographic—in particular if a taxpayer is allowed to lessen his tax base by declaring deductions or by leaving out some particular income elements from his taxable income. Proportional tax rates which are applied to lower-income categories could also be more progressive if such personal exemptions are declared.

Income measured over the period of a year may not absolutely come up with the best measure of taxpaying requirement. For example, transitory increases in income could be saved, and in temporary declines in income a taxpayer could choose to finance consumption by taking from savings. Thus, if taxation is held in comparison along with “permanent income,” it can be less regressive (or more progressive) than when compared with annual income.

Sales taxes and excises (except those on luxuries) tend to be regressive, because the portion of own income consumed or spent for a specific good lessens as the level of personal income is raised. Poll taxes (also termed head taxes), calculated as a standard amount per capita, patently are regressive.

It is difficult to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally because of the lack of certainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of deciding who bears the tax burden lays for the most part on whether a national or a subnational (that is, provincial or state) tax is being decided.

In considering the economic effect of taxation, it is relevant to distinguish between varied points of tax rates. The statutory rates will include those nominated in the legislation; usually these are marginal rates, but sometimes they are median rates. Marginal income tax rates signify the fraction of incremental income taken by taxation when income rises by one dollar. Hence, if tax onus grows by 45 cents when income rises by one dollar, the marginal tax rate is 45 percent. Income tax legislature commonly contain graduated marginal rates—i.e., rates that rise as income grows. Heavy analysis of marginal tax rates should take into account provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) lessens by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points higher 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 necessary ones for regarding incentive effects of taxation. It is even more complicated to understand the marginal effective tax rate applicable to income from business and capital, because it may be dependant on considerations including the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem holds that the marginal effective tax rate in income from capital is nil under a consumption-based tax.

Average income tax rates display the portion of total income that is demanded in taxation. The pattern of average rates is the one that is in consideration for judging the distributional equity of taxation. Under a progressive income tax the average income tax rate increases with income. Average income tax rates usually rise with income, both because personal allowances are provided for the taxpayer and dependents and also due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received for the most part by high-income households might dwarf these effects, allowing regressivity, as shown by average tax rates that decline as income grows.

The Development of Data Projectors

The LCDs utilised in projection systems are usually small reflective or transmissive panels lit by a bright arc lamp source. A number of lenses enlarges the reflected or transmitted image then displays it on a screen. For front-projection systems the LCD is set on the same area of the screen as the viewer, but in rear-projection systems the screen is lit up from behind. Projectors of greater cost and capability can utilise three separated LCD panels, forming separate red, green, and blue images that mesh to form a coloured image on the screen.

The growing desire for video presentations has granted a particular emphasis on the switching speed of liquid crystals. This has necessitated the creation of devices build with smectic liquid crystals, some of which give a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this time the most complex smectic device. With 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 within the layers the molecules are on a tilt, as displayed in the figure. The host liquid crystal holds optically active molecules, and a slight outcome of the optical activity and the angle 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 throughout 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 right sign can reverse the direction of this dipole in tens of microseconds and so reverse the tilt direction of the molecules. The consequential change in optical properties can make a change from light to dark when one or more polarizers are used.

SSFLC devices have been commercialized for large passive-matrix presentations, but their expense and complex detail has prevented them from creating any significant movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some probability for use as aspects in projection systems or as viewfinders in digital cameras. Their quick reacting allows them to be employed in time-sequential colour systems, in which costly colour filters are emulated with a coloured backlight that flashes red, green, and blue in quick pace (around 100 cycles every second). For example, the liquid crystal could be switched to a transmissive state for the red and green periods then to a nontransmissive state for the blue period, having the outcome 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 forms, the chair might be primary. While many other objects (apart from the bed) are intended to support objects, the chair supports your human form. The term chair is intended to be looked upon here in the most general sense, from stool to throne to derivative kinds including a bench and 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 evidently definitive.

The social history of the chair is as intriguing as its history as a creative craft. The chair is not just a physical support and aesthetic artwork; it is also semiotic of social standing. Within the past royal courts there were important distinctions between having a chair with arms, or a chair with a back but no arms, or worse having to utilise a stool. From the past century, a director’s and/or manager’s chair has risen an identifier of superior standing, and even in democratic government debate the speaker sits on a raised floor.

In a furniture purpose, the chair can be utilised for a number of different purposes. There are chairs manufactured to fit man’s age and physical capabilities (the high chair, the wheelchair) and for his standing in society (the executive chair, the throne). During the past there were chairs used for birthing (birth chairs); since the 20th century, there have been chairs used for ending life (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 can have chairs that can be folded up, chairs on wheels, and chairs on runners.

Our contemporary lifestyle has developed particular chairs for use in automobiles and aircraft. Each of these chair shapes has perfected to conform to changing human needs. Due to its unique connection with man, the chair appears to its full significance only when in use. Whereas it does not make a difference to one’s appreciation of a cupboard or a dresser drawers if there might be things inside or not, a chair is seen best and clearly evaluated by a person using it, because chair and sitter need each other. Thus the different elements of a chair are named like the elements of a human form: arms, legs, feet, back, and seat.

Because the simple work of your chair is to support the human body, its credit is judged firstly from how completely it does fulfill this practical use. In the manufacture of the chair, the chair maker is restricted under particular static rules and principal measurements. Inside these regulations, however, the chair maker has large freedom.

The history of the chair covered an era of several thousand years. There are societies that made distinctive chair forms, expressive of the principal task in the areas of craft and design. In these cultures, particular note 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 upshot of expert design, are found from discoveries made in tombs. First of these is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair had four legs shaped as akin to those of some animal, a curved seat, and leading to a sloping back supported by vertical stretchers. From this a durable triangular design was created. There was in our knowledge no notable differentiation in the construction of Egyptian thrones and chairs for ordinary people. The general change exists in the level of ornamentation, in the particulars of pricey inlays. The Egyptian folding stool most probably was manufactured to be an easily stored seat for soldiers. As a camp stool that type stayed around until much later points. But the stool also took on the role of a ceremonial seat, its original job as a folding stool being forgotten. This can now be seen, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They were made in the structure of folding stools but are not able to be folded as the seats were formed with wood. The plain construction of the folding stool, being of two frames that cycle on metal bolts and have a seat of leather or fabric fastened between them, reappeared at some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The better known of this form is the folding stool, of ashwood, seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The typical Greek chair, the klismos, is recognised not from any ancient object still extant but from a trove of pictorial objects. The most recognisable is the klismos displayed on the Hegeso Stele at the Dipylon burial place near Athens (c. 410 BC). It is a chair with a backward-sloping, curved backboard and four curving legs, but only two of them could be visible. These curving legs were most likely to be manufactured of bent wood and were in that case had to bear huge pressure with the weight of the sitter. The joints attaching the legs to the frame of the seat would have been therefore very strong and were overtly drawn.

The Romans emulated the Greek style; evidence of casts of seated Romans offer chairs of a thicker and in appearance slightly more crudely designed klismos. Both kinds, light or heavy, were brought back within the Classicist epoch. The klismos influence is known in French Empire furniture, in English Regency, and in some particular kinds of profound individuality within Denmark and Sweden from 1800.

China
The past of the chair in China is not able to be tracked as long as that of Egypt and Greece. Since the time of the Tang dynasty (AD 618–907) an unbroken serial of sketches and artworks had been kept safe, detailing the inside and exterior of Chinese households and their furniture. Preserved also of the 16th century are a trove of chairs of wood or lacquered wood, that bear an interesting likeness to pictures of past chairs.

Just the same as in Egypt, two fundamental chair forms existed in China: a chair with four legs and a folding stool. The four-legged chair is constructed both with and without arms although always having a square seat and straight stiles (vertical side supports) to support the back. In one form, it has been seen, the stiles were lightly curved over the arms to conform to the shape of the S-shaped back splat (the centre upright of a back). All three areas were mortised into the yoke-like top rail. Though the style of a back splat later had an introduction for English chairs during the Queen Anne period, wooden items that would merely to a particular extent reinforce corner joints (and furthermore were loose into the bargain) represent an element signatory to Chinese chairs. The four legs pass through the seat frame, which closes upon the rounded staves. Each member is round in section or is given rounded edges—referable maybe to the bamboo tradition. The seat is uncomfortable and might have had a plaited bottom. These chairs required the sitter to hold themselves stiff and upright; for when too much weight is exerted on the back, the chair has a way of collapsing. In patriarchal Chinese homes of this era armchairs most likely were kept for older individuals, for they were respected greatly.

The Chinese folding stool is believed to have travelled to China from the West. It does not vary that much from the Egyptian and Scandinavian folding stools, but it has a dissimilarity in that the top rail is elegantly affixed to the two legs of the stool by means of a curved member, which is more often than not designed with metal mounts. From a Western understanding the resulting effect of these furniture styles is stylized. The structure and decorative issues are combined in a manner that is simultaneously naïve and refined. The patchwork appearance is an upshot of the way that the individual items do not appear to have been fixed together by use of either glue or screws, but are mortised with one another and held in place in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also left its name on the chair. Works of art display a kind of chair with a relatively unrefined wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing between the layers, stitched to show up a pattern of tiny pads. The front board and a related board from the back could be folded after unscrewing some small iron hooks. Therefore the chair was an easily portable piece of furniture in traveling which, at the same era, 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 the interiors of rich Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. While this style of chair may also be seen in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not decided that the style actually started in The Netherlands. Normally, the legs of the chair will be smooth, round in section, and of slender measurements; they are in some cases baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was made in vast amounts, as evidenced from one of Abraham Bosse’s engravings, in which there is a whole row of such chairs lined up by a wall. The style asserts itself by its elegant proportions and delicate 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, to say, as developed in Paris around 1750—spread through most of Europe and has been imitated or copied during the mid-20th century. The style owes its popularity to a combination of comfort and elegance. The seat adheres to the human body and allows a relaxed sitting position. The back is bow-shaped, the legs curved. Typically the seat and back are upholstered, and there are little upholstered pads over the armrests. Smooth transitions are achieved between seat frame, legs, and back disguise all the joints, which are strongly constructed on craftsmanlike methodology even with the absence of stretchers between the legs.

French Rococo chairs and imitations of them employ wood of rather thick density; but all members are deeply molded, all extra wood has been taken away, and more expensive designs may be further embellished with very delicate and decorative engraving. The wood could be varnished, stained, painted, or gilded. Silk damask or tapestry should be used for all the upholstery on the seat, back, and armrests; cane is sometimes used as an alternative to upholstery.

English chairs in the 18th century were more differentiated in design than the French. The French manner for stylistic uniformity, which spread from the royal circles in Paris and Versailles over most of France and was popular 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 popular and was widely distributed throughout the world.

Late 18th to 20th century
In 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 brands 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 recordkeeping of the money values of the transactions of a business. Bookkeeping gives the figures from which accounts are written but is a previous process, required prior to accounting.

Fundamentally, bookkeeping grants two types of information: (1) the current value, or equity, of an entity and (2) changes in value—profit or loss—taking place in the entity over a particular period.

Management officials, investors, and credit grantors all have to have this kind of information: management to analyse 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 regard the financial statements of an enterprise in judging whether to give a loan.

Pieces of financial and numerical record charts are seen for just about every group of people with a commercial background. Records of business contracts have been found in the ruins of Babylon, and accounts for both farms and estates had been held in ancient Greece and Rome. The two-entry process of bookkeeping began with the development of the enterprising republics of Italy, and instruction manuals for bookkeeping were developed within the 15th century in many Italian cities.

Within the late 18th and early 19th centuries, the Industrial Revolution permitted an important stimulus to accounting and bookkeeping.

The rise of manufacturing, trading, shipping, and subsidiary services made perfect financial recordkeeping a paramount factor. The history of bookkeeping, in fact, reflects the past of commerce, industry, and government and, in part, assisted in shaping it. The global revolution of industrial and commercial activity called for more sophisticated decision-making methodology, which then demanded greater sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government legislation became more important and resulted in increased demand for information; firms had to provide information to go with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew, and the need for bookkeeping for their own departmental operations became higher.

While bookkeeping procedures can be rather detailed, it is all based on two types of books used in the bookkeeping procedure—journals and ledgers. A journal contains the daily transactions (sales, purchases, and such), and the ledger contains the record of individual accounts. The daily records from the journals are put in the ledgers.

Each month, generally speaking, an income statement and a balance sheet are prepared 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 those changes that occurred in the business equity because of the operations of the period. The balance sheet provides the financial situation of the business at a particular point in time taken from assets, liabilities, and the ownership equity.

Jet Power and the Birth of the Jet Aviation Age

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

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

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

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

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

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

The British ordered a jet-fighter flying-boat, but discovered that this way of doing business without airfields produced an inferior fighter. The Americans suffered similar problems with a ‘hydroski’ fighter, which could dive faster than sound, but took off and landed on retractable water skis.

Two even stranger fighters were designed around powerful turboprop engines and, standing on their tails, screwed themselves vertically into the air (they were intended to operate from the confined decks of warships or merchant vessels). Britain built high-altitude supersonic fighters with ‘mixed power’ from a turbojet and a rocket. In 1957 the British Minister of Defence suggested there would soon be no more manned fighters at all, only missiles. The Americans stuck to fighters, but made them very large and armed them with missiles, but no gun.

Today the wheel has turned full circle. In the past 10 to 20 years there has been a powerful 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.
