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

The most typical question asked when buying a new projector for the home, office, or classroom is: will I get an LCD projector or a DLP projector? LCD, standing for ‘liquid crystal device’ and DLP, short for ‘digital light processing’ are the two most common projector imaging technologies. With so many business brands and different types available, it can be difficult for the buyer to decide between these technologies. It comes down to the fact that LCD projectors provide far better image quality and colour accuracy. The next paragraph will explain why DLP projectors struggle with reproducing an equal standard of image quality.

It’s like a set of blinds in your home on your bedroom window. By pulling on a rod you can make the shutters open or closed, depending on if you want to let light in or not. And that is exactly how an LCD projector operates. Each pixel operates 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 experts 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 is switched on to when the content reaches your screen is ultimately significant for image quality, brightness and colour accuracy. LCD projectors process white light from the lamp by cutting 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 shining each pixel on and off. The pixels are then combined in a glass prism to deliver the projector image. A significant point to remember about LCD projectors is that all three colours are projected onto your projector screen at the same time. The way a DLP projector works is vastly different and even the produced image appears is not the same. With DLP, white light from the lamp is sent 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 forms a sequence of red, blue and green light. The millions of micro mirrors as 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 eyes will then draw each coloured element of the image into the complete image. From LCD projectors, all colours are available all the time to deliver the top level of brightness and superb colour accuracy. In DLP, just one colour is available at a time, and so resulting in lower colour brightness and accuracy. Some manufacturers have included a white segment for the colour wheel to improve all over brightness, but this goes and lessens colour accuracy.

I read in forums all the time that DLP provides a higher contrast ratio and as such must be better. For those who are unaware, the contrast ratio is a measure of a display system defined as the ratio of the luminance of the brightest white to that of the darkest black that the system is capable of producing. DLP projectors do have high contrast specifications when compared to most LCD projectors. At first glance, this seems to be an advantage, however, in real life, the true black level is determined by the ambient light in the room where the projector is being utilised. Do not be hoodwinked by contrast specifications on websites and in brochures.

When the content you wish to see needs moving images, DLP projection technology can also have image errors, or ‘artifacts’. The most common artifact that a DLP projector forms with moving images is colour break up. Colour break up is to be expected in DLP systems because moving images change up between the time red, blue and green colours are projected. LCD projectors do not have this downside because all the colours are delivered at once. DLP designers have developed 3DLP solutions using 3 chips to fix the colour break up issue, but the cost of these projectors make them not practical for the large part of businesses and consumers.

Another differentiation between LCD and DLP is how they compensate for the refractive qualities of light. Think back to high school science, and remember when they taught you how different colours of light refract various amounts when projected through the same lens. The downside with DLP projectors is that they take the one same panel with the same lens to project Red, Blue and Green. All 3 colours are obviously different and refract light in a different way. Often with a DLP projector, some yellow colour will show above and some blue will show below an image as simple as a lone black line. In building LCD projectors can be set to remove these effects on the projected image, because each colour is projected on a separate LCD panels.

The isolated true benefit (excluding price) with going with a DLP projector is its smaller overall size and weight. However, this is only relevant to transporting the device and must be traded off against the image benefits of LCD projectors. If the outcome of the picture quality is crucial to you, then the solution is no-brainer. Go with an LCD projector! LCD projectors will definitely produce bright, colourful images with fewer image errors.

Yachting and Yacht Clubs

As the Dutch found preeminence in sea power during the 17th century, the initial yacht had been a pleasure craft used first by royalty and then by the burghers in the canals as well as the protected and unprotected waters of the Low Countries. Racing yachts was incidental, arising as private challenges. English yachting started with King Charles II of England during his exile in the Low Countries. On his return 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 was found to be fashionable with the wealthy and royalty, but after that time the fashion 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 organization, and held large naval panoply and rigour. The closest thing to racing was the “chase,” when the “fleet” pursued a fictional enemy. The club endured, largely as a social club, until 1765, and in 1828, by merging with other organisations, it was known as the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing began in some organized manner on the Thames about the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV ascended to sovereignty in 1820, it was 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 formed at Cowes on the Isle of Wight in 1815, and royal funding made the Solent – the strait between the mainland and the Isle of Wight – the continuing location of British yachting. The association at Cowes became the Royal Yachting Club, also at the accession of George IV. Each member was required to have boats of at least 20 tons (20,321 kg). Sailing matches for large stakes were held, and the club life was splendid. Eventually Royal Yachting Club boats increased in size to more than 350 tons.

In North America, yachting was first accomplished with the Dutch in New York in the 17th century and continued when the English gained dominance. Sailing was largely for leisure and reached its high point in George Crowinshield’s Cleopatra’s Barge (1815), which cruised on the Mediterranean Sea and established a minimum of luxury and sophistication for the later yachts in those waters from the late 19th century. The first continuing American yacht group, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens instigated the New York Yacht Club while 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 later half of the 19th century. The craft of bigger yachts was initially greatly put upon by the victory of America, which was drawn by George Steers for a group led by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) found its namesake after its success at Cowes in 1851. Earlier yachts were not designed and built in a contemporary sense, with just a model used. Not until the later half of the 19th century did what was labeled naval architecture come into action. Not until the 1920s did the employment of the science of aerodynamics do for the craft of sails and rigging what such study had previously done for hulls.

Because nearly all sailboats had to be individually manufactured, there was a need for handicapping boats previous to the one-design class boats were built. Thus, a rating rule came into being, which is found in the International Rule, accepted in 1906 and revised in 1919. Today, one of the rapidly flourishing areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to the same dimensions in length, beam, sail area, and other aspects (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 uniform International America’s Cup Class taken on board for yachts in the 1992 America’s Cup race.

As long as yachting belonged mostly for the aristocracy and the affluent, expense was no object, and the size of boats increased, in both length and weight. The promotion and desire of smaller boats occurred in the later half of the 19th century in the sailing of the Englishmen R.T. McMullen, a stockbroker, and E.F. Knight, a barrister and journalist. A voyage around the world (1895–98) led single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray made plain the seaworthiness of small craft. Thereafter in the 20th century, notably after World War II, smaller racing and leisure boats became more common, down to the dinghy, a favourite training boat, of 3.7 m. In the late 20th century, yachts of less than 3 m were sailed single-handedly across the Atlantic Ocean.

Kinds of power yachts
Post the decade 1840–50, when steam was set to emulate sail power in market boats, the steam engine, and later the internal-combustion engine, were favoured increasingly in personal craft. Bigger power yachts were developed to a high standard, and long-distance cruising turned into a favourite pastime of the rich. The earliest power yachts were paddle-wheel boats; those then made way to yachts powered by the completely submerged screw or propeller sort of propulsion. As in the case of naval and merchant yachts, auxiliaries possessing both sail and power were the yacht fashion for a number of years. By the later half of the 20th century, many yachts were still auxiliaries, but the majority were only power yachts that had gasoline or diesel engines.

From the last decade of the 19th century there was a rise in the design of large steam yachts. In particular of these was the Mayflower (1897) of 2,690 tons, containing triple-expansion engines, twin screws, and a compartmented iron hull, and was manned by a crew of at least 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 during World War II.

As more sizeable and more dependable internal-combustion engines were created, many large yachts began using them for power. The establishment of the diesel engine, employing heavy oil for fuel, advanced during World War I. In the decade after that, big power-yacht building flourished, reaching a climax in the Orion (1930) at 3,097 tons. During that point the biggest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The building of large power yachts declined from 1932, and the trend thereafter was for smaller, less pricey yachts. After World War II, a lot of small naval vessels were sold to private owners for conversion to yachts. In the late 20th century, yachting had become a globally loved competition enjoyed by thousands of yachtsmen individually owning and upkeeping their own small recreational craft. The number of yachts and owners has increased steadily, not only in the traditional areas along the seacoasts but also on inland waterways and lakes.

Proportional, Progressive, and Regressive taxes

Taxes are differentiated by the effect they have on the placement of income and wealth. A proportional tax is a kind that impinges the same relative burden on each taxpayer—i.e., when tax liability and income increase in relative scale. A progressive tax is characterizable by a higher than proportional rise in the tax onus relative to the growth in income, and a regressive tax is recognised by a less than proportional growth in the comparative onus. Hence, progressive taxes are regarded as taking away a lack of equality in income distribution, but regressive taxes may have the effect of an increase in these inequalities.

The taxes that are often thought to be progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, might become less so for the upper-income categories—in particular if a taxpayer is allowed to lower his tax base by nominating deductions or by taking some particular income elements from his taxable income. Proportional tax rates when applied to lower-income demographics could also be more progressive if such personal exemptions are made.

Income measured over a given year might not definitely offer the most appropriate measure of taxpaying requirement. For example, transitory rises in income may be saved, and within temporary declines in income a taxpayer could choose 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 if compared with annual income.

Sales taxes and excises (with the exception of those on luxuries) are usually regressive, because the share of individual income consumed or spent for specific goods declines as the rate of personal income increases. Poll taxes (also known as head taxes), levied as a standard amount per capita, patently are regressive.

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

In analysing the economic purpose of taxation, it is relevant to distinguish between varied ideas of tax rates. The statutory rates will include those specified in the law; often these are marginal rates, but for some cases they are mean rates. Marginal income tax rates signify the fraction of incremental income that is demanded by taxation when income increases by one dollar. Hence, if tax liability grows by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax legislature generally contain graduated marginal rates—i.e., rates that rise as income increases. Structured analysis of marginal tax rates are required to take into account provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) decreases by 20 cents for each one-dollar rise in income, the marginal rate is 20 percentage points higher than specified within the statutory rates. Since marginal rates display how after-tax income changes in response to changes in before-tax income, they are the necessary ones for appraising incentive effects of taxation. It is even more difficult to understand the marginal effective tax rate to apply to income from business and capital, as it may be dependant on considerations 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 zero under a consumption-based tax.

Average income tax rates show the fraction of total income that is taken in taxation. The pattern of average rates is the one that is relevant for assessing the distributional equity of taxation. Under a progressive income tax the average income tax rate rises with income. Average income tax rates commonly grow 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 flip side, preferential treatment of income received predominantly by high-income households can dampen these effects, producing regressivity, as shown by average tax rates that decrease as income rises.

The Development of Data Projectors

The LCDs built for projection systems are most often small reflective or transmissive panels lit up by a forceful arc lamp source. A number of lenses enlarges the reflected or transmitted image and sends it on the screen. With front-projection systems the LCD is placed on the side of the screen as the viewer, but in rear-projection systems the screen is set off from behind. Projectors of higher expense and capacity might be found with three distinct LCD panels, forming separate red, green, and blue images that blend to make a coloured picture on the screen.

The increasing need for film displays has placed a growing emphasis on the switching speed of liquid crystals. This has demanded the manufacture of items using smectic liquid crystals, some kinds of which have a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is currently the most developed smectic device. In it the liquid crystal molecules are arranged in layers that are perpendicular to the substrate planes, which are distanced by one or two micrometres, and inside the layers the molecules are tilted, as illustrated in the figure. The host liquid crystal holds optically active molecules, and a minor 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. Therefore, there is 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 correct sign can reverse the direction of this dipole in tens of microseconds and in so doing reverse the tilt direction of the molecules. The respective change in optical properties can make a change from light to dark in the case that one or more polarizers are utilised.

SSFLC devices have been publicized for larger passive-matrix displays, but their cost and complex nature has stopped 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 elements in projection systems or as viewfinders in digital cameras. Their speedy responding allows them to be made use of in time-sequential colour systems, in which expensive colour filters are replaced by a coloured backlight that flashes red, green, and blue in rapid pace (about 100 cycles every second). For example, the liquid crystal can be switched to a transmissive state during the red and green periods 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 each of the furniture items, the chair may be the most imperative. While most other objects (save for the bed) are meant to support objects, the chair supports your human form. The term chair was viewed here in the most general sense, from stool to throne to derivative kinds for example a bench and sofa, which may be considered as extended or connected chairs, and whose character (i.e., whether they are intended for sitting or reclining) is not overtly labeled.

The social history of the chair is as exciting as its history as a creative craft. The chair is not merely a physical support and/or an aesthetic creation; it was also a symbol of social status. Within the Medieval royal courts there were clear distinctions between having a chair with arms, on a chair with a back but no arms, and having to squat on a stool. Since the past century, the director’s or manager’s chair has been an indicator of superior status, like in democratic government meeting the speaker sits on a high-set floor.

As its furniture creation, the chair is utilised for a range of various purposes. There are chairs designed to fit man’s age and physical abilities (the high chair, the wheelchair) and to show his position in society (the executive chair, the throne). Since past days there were chairs for birthing (birth chairs); during the 20th century, there have been chairs used for ending life (the electric chair). We make chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. We can make chairs that can be folded, chairs on wheels, and chairs on runners.

Our lifestyle has designated particular chairs for automobiles and aircraft. Each and every one of these chair types have been adapted to suit to different human uses. Due to its significant association with man, the chair lives to its full advantage only when being utilised. Though it doesn’t make a difference to one’s appreciation of a cupboard or a chest of drawers whether there are things inside or not, a chair is really understood and fairly evaluated with a person sitting in it, for chair and sitter need each other. Thus the several areas of the chair are given labels like the names of the human parts: arms, legs, feet, back, and seat.

Because the simple job of your chair is to support our body, its worth is judged firstly for how fully it does measure up to this practical use. In the structure of a chair, the chair maker is limited for some static regulations and principal measurements. In these restrictions, however, the chair creator has extensive freedom.

The history of the chair was an epoch of several thousand years. There were peoples that had made significant chair types, as expressions of the topmost object in the industries of craft and art. From such societies, special note can be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the upshot of skilled scheme, are now seen from discoveries made in tombs. First of the two is a four-legged chair with a back, the other a folding stool. The classical Egyptian chair would have four legs shaped similar to those of a designated animal, a curved seat, and a sloping back supported over vertical stretchers. In this way a stable triangular structure was made. There was from our understanding no noteworthy differentiation from the construction of Egyptian thrones and chairs for typical people. The only variation exists in the intricacy of ornamentation, in the selection of more valuable inlays. The Egyptian folding stool likely was designed for an easily packed seat for soldiers. As a camp stool that stool existed until much later days. But the stool then was created as the role of a ceremonial seat, its mechanical history as a folding stool simply forgotten. This can now be found, from as early as 1366–57 BC in two stools, executed in ebony with ivory inlay ornamentation and gold mounts, from the tomb of Tutankhamen. They were in the form of folding stools but aren’t able to be folded because the seats were worked with wood. The easy manufacture of the folding stool, composed of two frames that cycle on metal bolts and bear a seat of leather or fabric held between them, also appeared at some time later from the Bronze Age folding chairs of Scandinavia and northern Germany. The most recognised of those is the folding stool, from ashwood, seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The archetypal Greek chair, the klismos, is seen not in any ancient specimen still in form but in a wealth of pictorial objects. The iconic kind is the klismos posited on the Hegeso Stele at the Dipylon burial place by Athens (c. 410 BC). This klismos is a chair with a backward-sloping, curved backboard and four curving legs, but only two of those are seen. These odd legs were likely to be created out of bent wood and were therefore put under great pressure with the weight of the sitter. The joints attaching the legs to the frame of the seat are therefore extremely solid and were plainly denoted.

The Romans emulated the Greek designs; some casts of seated Romans offer chairs of a thicker and in appearance slightly less intricately constructed klismos. Both designs, the light or the heavy, were brought back within the Classicist time. The klismos design is found in French Empire styles, in English Regency, and in particular kinds of marked iconicism in Denmark and Sweden from 1800.

China
The progression of the chair in China is not able to be charted as far as the history of the chair in Egypt and Greece. From the Tang dynasty (AD 618–907) an unbroken folio of sketches and paintings was kept safe, showing the insides and outside of Chinese homes and the designs of furniture. Preserved also since the 16th century are a trove of chairs constructed of wood or lacquered wood, that display an interesting similarity to designs of previous chairs.

Same as in Egypt, there existed two particular chair forms in China: a chair with four legs and a folding stool. That four-legged chair can be constructed both with and without arms but never without the square seat and straight stiles (straight side supports) to support the back. In one form, it has been found, the stiles were slightly curved above the arms so as to fit the shape of the S-shaped back splat (the basic upright of a chairback). All three limbs are mortised on the yoke-like top rail. Despite that the innovation of a back splat later had an inspiration for English chairs from the Queen Anne period, wooden pieces that merely to a restricted ability embolden corner joints (and furthermore were loose as a result) are an element exclusive to Chinese chairs. The four legs sit through the seat frame, which ends around the rounded staves. All the members are round in section or have rounded edges—an acknowledgement perchance to the bamboo tradition. The seat is unpleasant to sit in and had on occasion a plaited texture. These chairs demanded of the sitter to hold themselves stiff and upright; for when too much pressure is exerted on the back, the chair has a habit of falling over. In patriarchal Chinese homes of this epoch armchairs probably were kept only for elderly family members, for they were greatly respected.

The Chinese folding stool is presumed to have been brought to China from the West. It does not vary very much from the Egyptian or Scandinavian folding stools, but it possesses a dissimilarity in that the top rail is intricately held to the two legs of the stool in a curved member, which is often possessing metal mounts. From a Western viewpoint the overall effect of both furniture styles is stylized. The structure and decorative aspects are combined in a way that is simultaneously naïve and refined. The piecemeal appearance is an outcome of the fact that the individual members do not look to have been fixed by use of either glue or screws, but are mortised into one another and fixed in its 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 display a kind of chair with a relatively unrefined wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing in between, stitched to bring up a pattern of small pads. The front board and a corresponding board in the back could be folded after unscrewing some small iron hooks. In this way the chair was an easily portable piece of furniture for traveling which, in the same era, gave the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair can be displayed in engravings of the interiors of rich Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Though this style of chair might also be made in countries where Dutch styles of interior decoration and Dutch furniture won favour, it is not determined that the style actually was born in The Netherlands. Usually, the legs of the chair are smooth, round in section, and of thin shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was made in considerable amounts, as can be surmised from one of Abraham Bosse’s engravings, in which an entire row of this kind of chairs lined up against a wall. The form asserts itself by virtue of its harmonious proportions and expensive upholstery in gilt leather or fabric edged with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature of forms—that was, as brought out in Paris around 1750—disseminated over most of Europe and was imitated or copied into the mid-20th century. The design owes such popularity to a combination of comfort and delicacy. The seat suits to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Generally the seat and back are upholstered, and there are small upholstered pads covering the armrests. Smooth transitions are made between seat frame, legs, and back cover all the joints, which are strongly constructed on craftsmanlike principles in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations of those have wood of fairly thick density; but every member is deeply molded, all extraneous wood has been cut away, and more upmarket items may be further embellished with very delicate and decorative woodwork. The wood can be varnished, stained, painted, or gilded. Silk damask or tapestry may be used for all of the upholstery on the seat, back, and armrests; crosshatched cane is occasionally used rather than upholstery.

English chairs of the 18th century were more variable in form than the French. The French manner for stylistic uniformity, which disseminated from the royal circles in Paris and Versailles through most of France and found favour in many parts of the Continent, had no parallel in England. Prior to 1740, the most commonly used wood was walnut; thereafter, and for the rest of the century, it was mahogany. Walnut, though beautiful in hue, was soft and therefore less suited to wood carving than to rounded, curving forms. Outer surfaces, such as the back and seat frame, were usually veneered. During the walnut period, highly overstuffed armchairs, covered with leather or embroidered material, were also developed. The best upholstery of this period is precisely and firmly modelled and accentuated by braiding or tacks. When imports of mahogany became common, no specifically new chair designs appeared, but the character of the woodwork changed. Mahogany, having a firmer, closer grain, could be cut thinner, which meant that individual parts of the chair could be more slender in shape. Mahogany also lent itself better to carving than walnut. Carving was concentrated more on the arms and back than on the legs, which as a rule were straight and smooth with chamfered (bevelled) edges and molding. There was a wealth of variety in chairback designs, featuring elegant, pierced, vase-shaped splats or two upright posts connected by horizontal slats (ladderback).

Alongside the French Rococo chair and the best English chairs in walnut and mahogany, the stick-back chair was relatively unaffected by the stylistic changes of the day. Originally a medieval form, known, for example, from paintings by Pieter Bruegel the Elder and still found in mid-20th century in the churches and inns of southern Europe, the stick-back chair (in all of its variations) consists basically of a solid, saddle-shaped seat into which the legs, back staves, and possibly the armrests are directly mortised. This typically peasant form underwent a renewal and a process of refinement in England and America during the 18th century. Under the name Windsor chair (a term that seems to have been used for the first time in 1731) or Philadelphia chair, it became well-known and was widely distributed throughout the world.

Late 18th to 20th century
Within the Neoclassical period, no basic changes took place in chair forms, but legs became straight and dimensions lighter. Backs in the shape of classical vases replaced the fanciful outlines of the Rococo period. Around 1800, freely executed imitations of Greek and Roman chairs of the klismos type, with curved legs and backrest, appeared. French chairs of the Empire period, executed in dark mahogany and embellished with ornate bronze mounts, created a ponderous effect.

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

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

Predominantly, bookkeeping provides 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 enterprise over a singular period of time.

Management officials, investors, and credit grantors all demand such information: management to analyse the outcomes of operations, to control costs, to budget for the future, and to make financial policy decisions; investors to assess the upshot of business operations and make decisions about buying, holding, and selling securities; and credit grantors to regard the financial statements of an enterprise in judging whether to give a loan.

Traces of financial and numerical charts can be found for nearly every group of people with a commercial history. Records of commercial contracts have been discovered in the archaelogy of Babylon, and accounts for both farms and estates were held in ancient Greece and Rome. The dual-entry style of bookkeeping started with the progression of the enterprising republics of Italy, and tutorials for bookkeeping were developed in the 15th century in various Italian cities.

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

The progression of manufacturing, trading, shipping, and subsidiary services made factual financial records a must-have. The past of bookkeeping, in fact, resembles closely the ancestry of commerce, industry, and government and, partially, helped in shaping it. The global expansion of industrial and commercial activity called for higher sophisticate decision-making procedures, which in its turn called for more sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government regulation became more important and resulted in higher demand for information; business entities had to have information available to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also grew in size, and the requirement for bookkeeping for their own inner departmental operations went up.

While bookkeeping methods can be very multifaceted, it is all 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 should have the record of individual accounts. The daily records in the journals are put in the ledgers.

Every month, by general practice, an income statement and a balance sheet are made from the trial balance posted out of the ledger. The point of the income statement or profit-and-loss statement is to present an analysis of any changes that occurred in the ownership equity resulting due to the operations of the period. The balance sheet provides the financial condition of the corporation at a 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 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.
