Think of a set of blinds in your home on your bedroom window. By pulling a rod you can make the shutters open or closed, according to whether you want to let light in or not. And this is exactly how an LCD projector behaves. Each pixel functions like a unique shutter on a set of blinds to either shine light through or to block it. DLP on the other hand is made up 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 when the projector turns on to when the content reaches your screen is ultimately significant for image quality, brightness and colour accuracy. LCD projectors project white light from the lamp by separating 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 processing each pixel on and off. The pixels are then meshed in a glass prism to send the projector image. Something important to realise about LCD projectors is that all three colours are directed onto your screen at the same time. The way a DLP projector operates is very different and even the way an image shows up is not the same. With DLP, white light from the lamp is directed through a turning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of creating an image forms a sequence of red, blue and green light. The millions of micro mirrors as mentioned above reflect the coloured light on the pixels to form 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 draw each coloured element of the image into a single whole image. From LCD projectors, all colours are available all the time to form the top level of brightness and superb colour accuracy. In DLP, just one colour is available at a time, causing lower colour brightness and accuracy. Some designers have put a white segment for the colour wheel to improve general brightness, but this also lessens colour accuracy.

I hear in forums all the time that DLP provides a higher contrast ratio and ergo must be better quality. For those 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 machine is able to produce. DLP projectors do possess high contrast specifications in comparison to a majority of LCD projectors. At a glance, this appears to be a plus, however, in real life, the true black level is determined by the ambient light in the room when the projector is utilised. Do not be tricked by contrast specifications on websites and in brochures.

When the content you are trying to project needs moving images, DLP projection technology can also create image marks, or ‘artifacts’. The most typical artifact that a DLP projector shows with moving images is colour break up. Colour break up is incontrovertible in DLP systems because moving images change up between the time red, blue and green colours are pulled up. LCD projectors do not have this characteristic because every colour is delivered with the others. DLP developers have formed 3DLP solutions using 3 chips to solve the colour break up error, but the cost of these projectors make them impractical for the majority of businesses and consumers.

Another point of difference between LCD and DLP is how they balance for the refractive qualities of light. Take yourself back to high school science, and remember how various colours of light refract varied amounts when directed through the same lens. The disadvantage 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 at different levels. Usually with a DLP projector, some yellow colour will show above and a superfluous blue will show below an image of something as simple as a lone black line. In manufacturing LCD projectors can be set to minimize these effects on the projected image, as each colour is processed on its own LCD panels.

The sole true benefit (excluding price) with taking a DLP projector is its overall smaller size and weight. However, this is only relevant with regard to transporting the device and cannot be traded off against the image plusses of LCD projectors. If the outcome of the picture quality is important to you, then the answer is easy. Go with an LCD projector! LCD projectors will always show bright, colourful images with fewer image mistakes.

The first yacht group in the British Isles, the Water Club, was started at about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, and held great naval panoply and formality. The closest thing to a race was the “chase,” when the “fleet” pursued an imagined enemy. The club persisted, for the large part as a social club, until 1765, and in 1828, by joining with other societies, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some organized fashion on the Thames around the mid-18th century. The duke of Cumberland instigated the Cumberland Fleet for Thames racing in 1775. When George IV rose to sovereignty in 1820, it was then called the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded with a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht association had been started at Cowes on the Isle of Wight in 1815, and royal funding made the Solent - the strait between the mainland and the Isle of Wight - the continued setting of British racing. The organisation at Cowes became the Royal Yachting Club, likewise at the accession of George IV. Every member was required to own boats of at least 20 tons (20,321 kg). Sailing tests for great bids were held, and the club life was splendid. Eventually Royal Yachting Club boats grew in size to more than 350 tons.

In North America, yachting started with the Dutch in New York in the 17th century and continued when the English gained dominance. Sailing was for the most part for fun and rose to its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and set a minimum of luxury and elegance for the later yachts in that area from the late 19th century. The first persisting American yacht club, the Detroit Boat Club, was started 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 latter half of the 19th century. The style of bigger yachts was first heavily put upon by the success of America, which was created by George Steers for a syndicate 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. The first yachts were not designed and built in today’s sense, with merely 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 application of the science of aerodynamics do for the craft of sails and rigging what it had earlier done for hulls.

Because nearly all sailboats had been 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, taken on in 1906 and edited in 1919. Today, one of the fastest growing areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to single dimensions in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing these boats can be done on an even par with no handicapping required. A perfect example is the standard International America’s Cup Class taken on for racers in the 1992 America’s Cup race.

So long as yachting was done largely for the nobility and the wealthy, money was no problem, and the size of boats developed, in both length and weight. The ascendancy and desire of smaller yachts came 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 journey 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 less sizeable craft. Later in the 20th century, notably after World War II, smaller racing and leisure craft became more common, down to the dinghy, a preferred 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 began to emulate sail power in commercial craft, the steam engine, and later the internal-combustion engine, were increasingly used in personal craft. Bigger power yachts were developed to a high element, and long-distance sailing was a fond activity of the rich. The earliest power yachts were paddle-wheel boats; those then made way to boats powered by the wholly submerged screw or propeller sort of propulsion. Like naval and merchant yachts, auxiliaries carrying both sail and power were the yacht fashion for many years. By the second half of the 20th century, several yachts were still auxiliaries, but the large part were exclusively power yachts containing gasoline or diesel engines.

In the last decade of the 19th century there was a rise in the construction of more sizeable steam yachts. In particular of these was the Mayflower (1897) of 2,690 tons, with triple-expansion engines, twin screws, and a compartmented iron hull, and was sailed by a crew of over 150. The Mayflower, purchased by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and was used in active service in World War II.

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

The building of big power boats lessened after 1932, and the fashion after that was in preference of smaller, less costly boats. After 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 internationally beloved sport enjoyed by thousands of yachtsmen who are actually manning and keeping their own small recreational yachts. The popularity of craft and yachtsmen is increasing steadily, not only in the traditional locations on the sea but also on inland waterways and lakes.

The taxes that are normally thought to be progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, might become less so in the upper-income class—particularly if a taxpayer is allowed to lower his tax base by claiming deductions or by excluding certain income elements from his taxable income. Proportional tax rates that are applied to lower-income groups would also be more progressive if exemptions of a personal nature are declared.

Income measured over the course of a given year does not absolutely provide the most appropriate measure of taxpaying status. For example, transitory growth in income might be saved, and within temporary declines in income a taxpayer might elect to finance consumption by reducing savings. Therefore, if taxation is held in comparison along with “permanent income,” it can be less regressive (or more progressive) than if compared with annual income.

Sales taxes and excises (save those on luxuries) tend to be regressive, because the spread of own income consumed or spent for specific goods lessens as the rate of personal income grows. Poll taxes (also termed head taxes), calculated as a flat amount per capita, obviously are regressive.

It is hard to classify corporate income taxes and taxes on business as progressive, regressive, or proportionate, principally due to a lack of certainty regarding the ability of businesses to shift their tax expenses (see below Shifting and incidence). This difficulty of dictating who bears the tax burden is dependant fundamentally on whether a national or a subnational (that is, provincial or state) tax is being determined.

In analysing the economic purpose of taxation, it is necessary to differentiate between varied concepts of tax rates. The statutory rates include those specified in legislation; usually these are marginal rates, but sometimes they are mean rates. Marginal income tax rates note the fraction of incremental income that is taken by taxation when income grows by one dollar. Thus, if tax burden increases by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax regulations usually contain graduated marginal rates—i.e., rates that increase as income rises. Careful analysis of marginal tax rates are required to review provisions in addition to the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) declines by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than nominated in the statutory rates. Since marginal rates indicate how after-tax income moves in response to changes in before-tax income, they are the necessary ones for assessing incentive effects of taxation. It is even more complicated to understand the marginal effective tax rate applied to income from business and capital, as it may rely on considerations such as the structure of depreciation allowances, the deductibility of interest, and the provisions for inflation adjustment. A basic economic theorem holds that the marginal effective tax rate in income from capital is zero under a consumption-based tax.

Average income tax rates display the percentage of total income that is paid 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 generally rise with income, both because personal allowances are provided for the taxpayer and dependents and due to that marginal tax rates are graduated; conversely, preferential treatment of income received predominantly by high-income households can swamp these effects, producing regressivity, as indicated by average tax rates that decrease as income rises.

The increasing desire for pictographic presentations has granted a particular emphasis on the switching speed of liquid crystals. This has required the manufacture of objects utilizing smectic liquid crystals, certain kinds of which have a better electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most complex smectic device. In it the liquid crystal molecules are managed in layers that are perpendicular to the substrate planes, which are separated by one or two micrometres, and inside the layers the molecules are tilted, as shown in the figure. The host liquid crystal possesses optically active molecules, and a minor result of the optical activity and the tilt of the molecules is the appearance of a permanent charge separation, or ferroelectric dipole, similar to the ferromagnetic dipole of a magnet. The direction of this dipole is perpendicular to the tilt direction of the molecules and through the plane of the layers. Therefore, there exists a permanent charge separation through 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 right sign can reverse the direction of this dipole in tens of microseconds and therefore reverse the tilt direction of the molecules. The resultant change in optical properties can create a change from light to dark in the case that one or more polarizers are employed.

SSFLC devices have been commercialized for large passive-matrix presentations, but their expense and intricacy has stopped them from having any great effect on the market. Small transmissive and reflective active-matrix SSFLC displays, however, show some promise for use as parts 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 high cost colour filters are replaced with a coloured backlight that flashes red, green, and blue in rapid speed (about 100 cycles a second). For example, the liquid crystal can be switched to a transmissive state between the red and green periods but then to a nontransmissive state in the blue period, having the end result that the eye sees an average of red and green light, or the colour yellow.

The social history of the chair is as exciting as its history as a creative art. The chair is not merely a physical support and an aesthetic piece; it was also an indicator of social hierarchy. At the Medieval royal courts there were important signifiers between having a chair with arms, or a chair with a back but without arms, and having to squat on a stool. Since the past century, the director’s and manager’s chair has been regarded as a signifier of superior rank, as well as in democratic government debate the speaker sits on a raised floor.

In its furniture construction, the chair can be utilised for a number of different makes. There are chairs designed to attend to man’s age and physical condition (the high chair, the wheelchair) and to indicate his rank in society (the executive chair, the throne). During past days there were chairs to be born in (birth chairs); from the 20th century, there have been chairs 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 make chairs that can be folded up, chairs on wheels, and chairs on runners.

Modern living has designated particular chairs in automobiles and aircraft. Every one of these chair kinds has evolved to conform to growing human needs. Because of its significant importance with man, the chair comes to its full advantage only when in use. Whereas it makes no difference to one’s appreciation of a cupboard or a bureau whether there might be things inside or not, a chair is understood and fairly tested with a person sitting on it, because chair and sitter complement one another. Thus the individual limbs of a chair are labeled corresponding to the areas of a human parts: arms, legs, feet, back, and seat.

Because the obvious purpose of a chair is to support a body, its credit is evaluated principally on how completely it does fulfill this practical role. Within the construction of a chair, the builder is limited by some static legislation and principal measurements. Inside these regulations, however, the chair maker has extensive freedom.

The history of the chair covers an era of several thousand years. There are civilizations that made significant chair types, expressions of the premier work in the arenas of skill and aesthetics. From such peoples, individual 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 reigns of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of masterful design, were a finding from tombs. The first one of these is a four-legged chair with a back, the other a folding stool. The iconic Egyptian chair would have four legs formed not unlike those of some animal, a curved seat, with a sloping back supported over vertical stretchers. In this design a stable triangular structure was obtained. There appeared to be no notable variation in the construction of Egyptian thrones and chairs for typical non-royals. The simple variation lies in the type of ornamentation, in the selection of pricey inlays. The Egyptian folding stool most probably was manufactured to be an easily packed seat for officers. As a camp stool this type persevered during much later times. But the stool then was made for the role of a ceremonial seat, its mechanical history as a folding stool neglected or forgotten. This can now be found, from as early as 1366–57 BC in two stools, created in ebony with ivory inlay work and gold mounts, from the tomb of Tutankhamen. They are made in the shape of folding stools but can’t be folded because the seats were worked of wood. The plain build of the folding stool, being of two frames that cycle on metal bolts and have a seat of leather or fabric held between them, came again but somewhat later in the Bronze Age folding chairs of Scandinavia and northern Germany. The better known of these is the folding stool, made of ashwood, which can now be found at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The iconic Greek chair, the klismos, is found not with any ancient fossil still around but from a trove of pictorial objects. The most recognisable is the klismos depicted on the Hegeso Stele at the Dipylon burial location by Athens (c. 410 BC). The klismos is a chair that had a backward-sloping, curved backboard and four curving legs, but only two of those legs would be displayed. These strange legs were likely to have been created in bent wood and were as such needed to bear extreme pressure from the weight of the sitter. The joints holding the legs to the frame of the seat had to be therefore super strong and were visibly denoted.

The Romans emulated the Greek chair; quite a few casts of seated Romans offer chairs of a heavier and in appearance rather more crudely built klismos. Both designs, the light and the heavy, were seen again during the Classicist period. The klismos design can be evidenced in French Empire styles, in English Regency, and in particular forms of profound originality around Denmark and Sweden around 1800.

China
The progression of the chair in China cannot be traced as far back as in Egypt and Greece. From the Tang dynasty (AD 618–907) a full series of sketches and artworks has been kept, with images of the inside and exteriors of Chinese buildings and the kinds of furniture. Kept also of the 16th century are a trove of chairs made from wood or lacquered wood, that bear an intriguing likeness to images of older chairs.

Just as in Egypt, there were two fundamental chair forms in China: a chair that had four legs and a folding stool. This four-legged chair can be seen both with and without arms however always with its square seat and straight stiles (upright side supports) to hold up the back. In one design, it has been seen, the stiles are slightly curved over the arms to conform correctly to the structure of the S-shaped back splat (the basic upright of a back). Together, the three parts were mortised in the yoke-like top rail. Though the design of this back splat had a foundation for English chairs during the Queen Anne period, wooden sections that would only to a restricted ability reinforce corner joints (and were loose to top it off) are a design solely to Chinese chairs. The four legs sit through the seat frame, which stops around the rounded staves. Members are round in section or has rounded edges—references as may be to the bamboo tradition. The seat is not comfortable and may have had a plaited seat. These chairs required of the sitter to remain stiff and upright; for if too much weight is placed on the back, the chair has a tendency to fall. In patriarchal Chinese households of this epoch armchairs probably were reserved for the senior persons in the family, for they were held in great respect.

The Chinese folding stool is understood to have been brought to China from the West. It is not dissimilar much from the Egyptian and Scandinavian folding stools, but it has a change in that the top rail is delicately affixed to the two legs of the stool by a curved member, which is usually designed with metal mounts. From a Western perspective the ultimate effect of both these furniture forms is stylized. The manufacture and decorative elements are combined in a style that is both naïve and refined. The pieced-together appearance is an outcome of the fact that the individual members do not look to have been held together with either glue or screws, but were mortised into one another and held in position in the style of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain of the 17th century also left its signature on the chair. Works of art display a design of chair with a relatively unrefined wooden frame; a back and seat, nailed on, with two layers of leather, with horsehair stuffing between, stitched to bring up a pattern of little pads. The front board and a corresponding board from the back could be folded after loosening some little iron hooks. In this way the chair was a portable piece of furniture in traveling which, at the same time, possessed the dignity of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered type of chair is displayed in engravings of the interiors of affluent Dutch homes by Abraham Bosse, a French artist, as well as in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this kind of chair can also be made in countries where Dutch styles of interior decoration and Dutch furniture won preference, it is not decided that the innovation actually started in The Netherlands. Usually, the legs of the chair were smooth, round in section, and of thin shape; they are in some cases baluster-shaped (vase-shaped) or twisted. It is patently a bourgeois piece of furniture and was crafted in considerable quantities, 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 style asserts itself with its shapely proportions and fine 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 styles—that is to say, as created in Paris around 1750—spread through most of Europe and has been imitated or copied into the mid-20th century. The style owes the popularity to a combination of comfort and elegance. The seat suits to the human body and grants a relaxed sitting position. The back is bow-shaped, the legs curved. Usually the seat and back are upholstered, and there are little upholstered pads on the armrests. Smooth transitions achieved between seat frame, legs, and back conceal all the joints, which are constructed strongly on craftsmanlike methodology despite the absence of stretchers between the legs.

French Rococo chairs and imitations of those are constructed from wood of relatively thick dimensions; but every member is deeply molded, all superfluous wood has been removed, and finer chairs would be further embellished with special delicate and decorative woodwork. The wood may be varnished, stained, painted, or gilded. Silk damask or tapestry might be used for any upholstery on the seat, back, and armrests; canework is sometimes used instead of upholstery.

English chairs in the 18th century were more variable in style than the French. The French manner for stylistic uniformity, which disseminated from the royal circles in Paris and Versailles within most of France and found favour 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
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.

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.

Basically, bookkeeping finds two areas of information: (1) the current value, or equity, of an enterprise and (2) changes in value—profit or loss—taking placement in the enterprise within a given period.

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

Traces of financial and numerical records are found for nearly every society with a commercial backbone. Records of commercial contracts have been discovered in the ruins of Babylon, and accounts for both farms and estates had been kept in ancient Greece and Rome. The two-entry way of bookkeeping began with the development of the business republics of Italy, and tutorials for bookkeeping were developed within the 15th century in many Italian cities.

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

The rise of manufacturing, trading, shipping, and subsidiary services made correct financial records a necessity. The history of bookkeeping, in fact, resembles the ancestry of commerce, industry, and government and, partially, helped forming it. The worldwide expansion of industrial and commercial activity demanded higher cosmopolitan decision-making methods, which in turn demanded more sophistication in the selection, classification, and presentation of information, even more so with the aid of computers. Taxation and government legislation became more significant and resulted in higher need for information; businesses had to provide information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also developed in size, and the requirement for bookkeeping for departmental operations became larger.

Though bookkeeping methods can be extremely complex, all are based on two types of books employed in the bookkeeping process—journals and ledgers. A journal must have the daily transactions (sales, purchases, and such), and the ledger must have the records of individual accounts. The daily records from the journals are written in the ledgers.

At the end of each month, generally, an income statement and a balance sheet are made from the trial balance posted within the ledger. The duty of the income statement or profit-and-loss statement is to give an analysis of those changes that took place in the business equity from the events of the period. The balance sheet displays the financial position of the business at a particular day in terms of assets, liabilities, and the ownership equity.

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 resulted in 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.
