Visualise a set of blinds in your home over your bedroom window. By pulling a rod you can make the shutters open or closed, according to if you want to let light in or not. This is exactly how an LCD projector functions. Each pixel functions like a unique shutter on a set of blinds to either pass light through or to block it. DLP on the other hand is constructed of millions of microscopic mirrors or ‘pixel elements’ as pros like to call them. Each pixel element works to either reflect light or block it.

How the light source is processed from the point when the projector switches on to when the picture reaches your screen is ultimately significant to 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 send the coloured light to 3 individual LCD panels. The 3 LCD panels create the elements of the image by turning each pixel on and off. The pixels are then combined in a glass prism to create the projector image. Something important to understad about LCD projectors is that all three colours are delivered onto your screen simultaneously. The way a DLP projector works is very different and even the final product of how an image shows up is not the same. With DLP, white light from the lamp is processed through a spinning colour wheel with transparent red, blue and green segments, at speeds up to 11,000 rpm/s. This method of creating an image casts 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 cast in sequence on the screen, one colour at a time. The viewer’s eye will then pull together each coloured element of the image into a total image. With LCD projectors, all colours are available all the time to deliver the top level of brightness and spectacular colour accuracy. In DLP, only one colour is available at any given time, resulting in lower colour brightness and accuracy. Some designers have added a white segment in the colour wheel to improve all over brightness, but this goes and detracts from colour accuracy.

I hear in forums all the time that DLP gives a higher contrast ratio and thus must be superior. 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 projector is capable of producing. DLP projectors do provide high contrast specifications compared to the majority of LCD projectors. Initially, this seems to be a benefit, however, in the real world, the true black level is determined by the ambient light in the room when the projector is utilised. Do not be fooled by contrast specifications on websites and in brochures.

When the content you plan to bring to life includes moving images, DLP projection technology also creates image imperfections, or ‘artifacts’. The most typical artifact that a DLP projector creates with moving images is colour break up. Colour break up is to be expected in DLP systems because moving images change position between the time red, blue and green colours are pulled up. LCD projectors do not have this downside because the colours are delivered at once. DLP manufacturers have come up with 3DLP solutions using 3 chips to fix the colour break up error, but the cost of these projectors make them hardly practical for the majority of businesses and consumers.

Another differentiation between LCD and DLP is how they make up for the refractive qualities of light. Jump back to high school science, and recall when they taught you how the various colours of light refract different amounts when shone through the same lens. The downside with DLP projectors is that they take the one same panel and the same lens to project Red, Blue and Green. All 3 colours are not the same and refract light differently. Often with a DLP projector, a spill of yellow colour will appear above and a superfluous blue will be projected below an image containing something as simple as a straight black line. In manufacturing LCD projectors can be adapted to remove these effects on the projected image, because each colour is directed on a separate LCD panels.

The one real benefit (excluding price) with choosing a DLP projector is its overall smaller size and weight. However, this is only relevant for transport and needs to be traded off against the image advantages of LCD projectors. If the result of the picture quality is important to you, then the answer is simple. Go with an LCD projector! LCD projectors will consistently make bright, colourful images with fewer image mistakes.

The first yacht association in the British Isles, the Water Club, was formed in about 1720 at Cork, Ire., as a cruising and unofficial coast guard association, with large naval panoply and formality. The closest thing to racing was the “chase,” for which the “fleet” pursued an imaginary enemy. The club went on, mostly as a social club, until 1765, and in 1828, when merging with other societies, it became the Cork Yacht Club (later the Royal Cork Yacht Club).

Yacht racing was first seen in some stipulated fashion on the Thames around the mid-18th century. The duke of Cumberland funded the Cumberland Fleet for Thames racing in 1775. When George IV came to monarchy in 1820, it was then named the Fleet to His Majesty’s Coronation Sailing Society. The Thames Yacht Club seceded following a racing fight, to become the Royal Thames Yacht Club in 1830. The first English yacht society 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 continuing location of British yacht racing. The society at Cowes became the Royal Yachting Club, likewise at the ascension of George IV. All members were required to possess boats of at least 20 tons (20,321 kg). Sailing matches for large bets were held, and the club life was wonderful. Ultimately 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 went on when the English had power. Sailing was for the most part for fun and reached its apogee in George Crowinshield’s Cleopatra’s Barge (1815), which sailed on the Mediterranean Sea and established a minimum of luxury and elegance for the later yachts in that area from the late 19th century. The first enduring American yacht society, the Detroit Boat Club, was formed in 1839. In 1844, John C. Stevens began the New York Yacht Club while aboard his schooner Gimcrack.

Kinds of sailboats
The Early sailing yachts followed the lines of such naval craft as brigantines, schooners, and cutters from the 17th century through the latter half of the 19th century. The style of bigger yachts was initially greatly put upon by the victory of America, which was drawn by George Steers for a club started by John C. Stevens, and it was the boat for which the America’s Cup (q.v.) was named after its success at Cowes in 1851. Early yachts were not designed and built in a contemporary sense, with only a model being used. Not until the later half of the 19th century did what was known as naval architecture come about. Not until the 1920s did the use of the science of aerodynamics do for the design of sails and rigging what such study had done earlier for hulls.

Because nearly all sailboats were individually manufactured, there was a desire for handicapping boats previous to the one-design class boats were built. Hence, a rating rule came into being, which ended up in the International Rule, taken on in 1906 and edited in 1919. In the present day, one of the fastest flourishing areas in sailing is that of one-design class boats. All boats in a one-design class are manufactured to the same requirements in length, beam, sail area, and other aspects (for an example of a two-person sailboat, see illustration). Racing for such boats can be held on an even playing field with no handicapping necessary. A prime example is the standard International America’s Cup Class taken on for racers in the 1992 America’s Cup race.

For the time that yachting was done largely for the aristocracy and the affluent, money was no object, and the size of boats grew, in both length and weight. The promotion and popularity of smaller yachts happened in the latter 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 trip around the world (1895–98) sailed single-handedly by the naturalized American captain Joshua Slocum in the 11.3-metre Spray proved the seaworthiness of small boats. Thereafter in the 20th century, for the larger part after World War II, smaller racing and pleasure yachts became commonplace, down to the dinghy, a preferred 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
Following the decade 1840–50, during which steam was set to replace sail power in market vessels, 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 cruising turned into a fond occupation of the wealthy. The early power yachts were paddle-wheel boats; they then gave way to boats powered by the fully submerged screw or propeller sort of propulsion. Like 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, several yachts were still auxiliaries, but the large part were exclusively power yachts with gasoline or diesel engines.

From the last decade of the 19th century there was a boom in the manufacture of large steam yachts. Conspicuous within 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 more than 150. The Mayflower, bought by the United States Navy in 1898, was the official yacht of the president of the United States until 1929 and saw active service during World War II.

As more sizeable and more reliable internal-combustion engines were produced, many bigger yachts began using them for power. The creation of the diesel engine, with heavy oil for fuel, was furthered in World War I. From the decade after that, bigger power-yacht building flourished, reaching a climax in the Orion (1930) at 3,097 tons. During that point the largest auxiliary yacht manufactured was the four-masted, steel, barque-rigged Sea Cloud (1931) of 2,323 tons.

The manufacture of large power yachts lessened in 1932, and the trend from then was for smaller, less expensive yachts. Following World War II, many small naval boats were sold to private owners for conversion to yachts. At the late 20th century, yachting is a globally popular competition enjoyed by thousands of yachtsmen personally manning and upkeeping their own small recreational boats. The number of yachts and owners increased steadily, not only in the traditional locations on the beach but also on inland waterways and lakes.

The taxes that are normally regarded as progressive include individual income taxes and estate taxes. Income taxes that are nominally progressive, however, might become less so within the upper-income categories—particularly if a taxpayer is able to lower his tax base by declaring deductions or by taking some income elements from his taxable income. Proportional tax rates if applied to lower-income classes would also be more progressive if exemptions of a personal nature are declared.

Income measured over the period of a given year may not absolutely provide the most suitable measure of taxpaying ability. For example, transitory growth in income may be saved, and during temporary declines in income a taxpayer may opt to provide for consumption by reducing savings. Ergo, if taxation is compared along with “permanent income,” it would be less regressive (or more progressive) than if compared with annual income.

Sales taxes and excises (except those on luxuries) are mostly regressive, because the spread of one’s income consumed or spent on specific goods declines as the rate of personal income grows. Poll taxes (aka head taxes), nominated as a standard amount per capita, clearly are regressive.

It is not simple to dictate corporate income taxes and taxes on business as progressive, regressive, or proportionate, because of the uncertainty around 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 essentially on whether a national or a subnational (that is, provincial or state) tax is being considered.

In assessing the economic purposes of taxation, it is necessary to differentiate between differing points of tax rates. The statutory rates include those dictated in law; generally speaking these are marginal rates, but for some cases they are average rates. Marginal income tax rates note the fraction of incremental income that is demanded by taxation when income increases by one dollar. So, if tax onus grows by 45 cents when income grows by one dollar, the marginal tax rate is 45 percent. Income tax regulations often contain graduated marginal rates—i.e., rates that grow as income grows. Heavy analysis of marginal tax rates should review provisions as well as the formal statutory rate structure. If, for example, a particular tax credit (reduction in tax) reduces by 20 cents for each one-dollar increase in income, the marginal rate is 20 percentage points more than specified by the statutory rates. Since marginal rates specify how after-tax income changes in response to changes in before-tax income, they are the important 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, as it may rely on such factors 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 determine the percentage of total income that is taken in taxation. The pattern of average rates is the one that is in consideration for appraising the distributional equity of taxation. Under a progressive income tax the average income tax rate grows with income. Average income tax rates generally increase with income, both because personal allowances are granted for the taxpayer and dependents and due to that marginal tax rates are graduated; on the other hand, preferential treatment of income received mostly by high-income households might dampen these effects, allowing regressivity, as displayed by average tax rates that decrease as income increases.

The growth in desire for visual presentations has put a growing emphasis on the switching speed of liquid crystals. This has necessitated the manufacture of items using smectic liquid crystals, certain ones of which possess a faster electro-optical response than nematic liquid crystals. The surface-stabilized ferroelectric liquid crystal (SSFLC) display is at this point the most progressive smectic device. With it the liquid crystal molecules are arranged in layers perpendicular to the substrate planes, which are differentiated by one or two micrometres, and inside the layers the molecules are on a slant, as illustrated in the figure. The host liquid crystal contains optically active molecules, and a subtle turn up of the optical activity and the angle of the molecules is the presence 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. Hence, there exists a permanent charge separation across the liquid crystal layer in the SSFLC, and its sign is directly attracted to the tilt direction of the molecules. An applied voltage of the right sign can reverse the direction of this dipole in tens of microseconds and hence reverse the tilt direction of the molecules. The consequential change in optical properties can create a change from light to dark when one or more polarizers are employed.

SSFLC devices have been commercialized for bigger passive-matrix displays, but their high cost and complex detail has impeded them from enjoying any significant movement on the market. Small transmissive and reflective active-matrix SSFLC displays, however, display some possibility for use as parts in projection systems or as viewfinders in digital cameras. Their speedy responding allows them to be used in time-sequential colour systems, in which highly expensive colour filters are emulated by a coloured backlight that flashes red, green, and blue in fast pulsing (about 100 cycles in a second). For example, the liquid crystal could be switched to a transmissive state for the red and green periods and then to a nontransmissive state during the blue period, creating the upshot 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 art and craft. The chair is not simply a physical support or an aesthetic creation; it was also an indicator of social placement. In the old royal courts there were clear differences between being seated on a chair with arms, or a chair with a back but no arms, or having to utilise a stool. From the 20th century, a director’s or manager’s chair has been regarded as a signifier of superior standing, like in democratic government meeting the speaker sits on a higher level.

In its furniture creation, the chair is utilised for a variety of various purposes. There are chairs structured to suit man’s age and physical form (the high chair, the wheelchair) and to connotate his position in society (the executive chair, the throne). From past days there were chairs for birthing (birth chairs); from the 20th century, there have been chairs to die in (the electric chair). We make chairs with one, two, three, or four legs, chairs with or without arms, and chairs with or without backs. There are chairs that can be folded and put away, chairs on wheels, and chairs on runners.

Modern living has derived unique chairs for use in automobiles and aircraft. All of these chair shapes has evolved to conform to changing human desires. From its close association with man, the chair comes to its full meaning only when used. Although it is irrelevant to one’s appreciation of a cupboard or a chest of drawers if there might be things inside or not, a chair is really seen best and fairly tested with a person sitting on it, for chair and sitter require each other. Thus the several elements of the chair have been named corresponding to the names of a human body: arms, legs, feet, back, and seat.

Because the obvious function of a chair is to support our human body, its value is valued primarily for how fully it measures up to this practical use. In the structure of the chair, the maker is bound by some static laws and principal measurements. Within these restrictions, however, the chair maker has awesome freedom.

The history of the chair covered dates of several thousand years. There is evidence of cultures that had made distinctive chair types, as expressive of the topmost task in the arenas of handling and creativity. Within these societies, special note must be made of ancient Egypt and Greece; China; Spain and The Netherlands in the 17th century; England in the 18th century; and France in the 18th century during the ascendancy of Louis XV and Louis XVI.

Egypt
Two ancient Egyptian chair forms, both the items of skilled craft, are today known from discoveries made in tombs. One of them is a four-legged chair with a back, the other a folding stool. The original Egyptian chair would have had four legs structured akin to those of some animal, a curved seat, with a sloping back supported from vertical stretchers. From this a strong triangular form was obtained. There was from our view no noteworthy change in the construction of Egyptian thrones and chairs for common citizens. The only change exists in the intricacy of its ornamentation, in the selection of more costly inlays. The Egyptian folding stool most likely was crafted to be an easily carried seat for officers. As a camp stool the type stayed around during much later points in time. But the stool also was made for the role of a ceremonial seat, its mechanical task as a folding stool neglected or forgotten. This can from today’s evidence be seen, from as early as 1366–57 BC in two stools, formed in ebony with ivory inlay decoration and gold mounts, from the tomb of Tutankhamen. They were made in the construction of folding stools but can not be folded as the seats were formed of wood. The simple build of the folding stool, being of two frames that rotate on metal bolts and have a seat of leather or fabric held between them, came up but some time later during the Bronze Age folding chairs of Scandinavia and northern Germany. The best recognised of this kind is the folding stool, from ashwood, now seen at Guldhøj (National Museum in Copenhagen).

Greece and Rome
The significant Greek chair, the klismos, is seen not in any ancient fossil still in form but from a variety of pictorial objects. The most well known is the klismos seen on the Hegeso Stele at the Dipylon burial ground outside 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 would be visible. These unique legs were presumed to have been created of bent wood and were in that case had great pressure with the weight of the sitter. The joints securing the legs to the frame of the seat were therefore extremely durable and were clearly signified.

The Romans borrowed from the Greek design; evidence of casts of seated Romans are designs of a heavier and in appearance slightly more crudely designed klismos. Both designs, the light and the heavy, were seen again in the Classicist time. The klismos influence can be found in French Empire furniture, in English Regency, and in some particular forms of notable originality within Denmark and Sweden circa 1800.

China
The history of the chair in China is not able to be tracked as long as the ancestry of chairs in Egypt and Greece. From the time of the Tang dynasty (AD 618–907) an unbroken serial of images and paintings had been kept, displaying the interiors and outer parts of Chinese houses and the furniture. Kept also from the 16th century are a number of chairs of wood or lacquered wood, that display an interesting resemblance to designs of ancient chairs.

As in Egypt, there were two standard chair forms in China: a chair that had four legs and a folding stool. That four-legged chair is found both with and without arms however always with its square seat and straight stiles (upright side supports) to hold up the back. In one style, it has been seen, the stiles were delicately curved above the arms in order to fit the shape of the S-shaped back splat (the central upright of its chairback). Together, all three areas had been mortised onto the yoke-like top rail. Although the innovation of this back splat had a foundation for English chairs of the Queen Anne period, wooden items that could only to a limited extent reinforce corner joints (and were loose additionally) indicate a design solely to Chinese chairs. The four legs sit through the seat frame, which ends upon the rounded staves. All members are round in section or has rounded edges—references perchance to the bamboo tradition. The seat is not comfortable and might have had a plaited bottom. These chairs required the sitter to hold themselves stiff and upright; when too much weight is placed on the back, the chair has a tendency to fall over. In patriarchal Chinese households of this epoch armchairs most likely were kept for older persons in the family, for they were given great respect.

The Chinese folding stool is thought to have travelled to China from the West. It does not vary so very much from the Egyptian or Scandinavian folding stools, but it possesses a change in that the top rail is prettily affixed to the two legs of the stool with a curved member, which is often provided with metal mounts. From a Western perspective the ultimate effect of these two furniture designs is stylized. The constructive and aesthetic issues are combined in a way that is all at once both naïve and refined. The piecemeal appearance is an upshot of the fact that the individual members do not appear to have been put together by means of either glue or screws, but have been mortised into one another and held in its place in the manner of a Chinese puzzle.

Spain: 17th century
The Golden Age of Spain in the 17th century also left its mark on the chair. Artworks project a kind of chair with a relatively brusque wooden frame; a back and seat, nailed on, possessing two layers of leather, with horsehair stuffing in between the layers, stitched to bring out a pattern of little pads. The front board and a corresponding board from the back could be folded after unscrewing some small iron hooks. Therefore the chair was an easily portable piece of furniture when traveling which, during the same period, gave the status of a four-legged, high-backed armchair.

The Netherlands: 17th century
A low, square, upholstered kind of chair can be evidenced in engravings of interiors of wealthy Dutch homes by Abraham Bosse, a French artist, and also in paintings by the Dutch artists Johannes Vermeer and Gerard Terborch. Although this design of chair may also be made in countries in which Dutch styles of interior decoration and Dutch furniture won favour, it is not believed that the innovation actually began in The Netherlands. Usually, the legs of the chair were smooth, round in section, and of slender shape; they are occasionally baluster-shaped (vase-shaped) or twisted. It is obviously a bourgeois piece of furniture and was crafted in large numbers, as can be seen from one of Abraham Bosse’s engravings, in which there is a row of these chairs lined up against a wall. The design asserts itself with its harmonious proportions and expensive upholstery in gilt leather or fabric bordered with fringes.

France and England: 17th and 18th centuries
The French Rococo chair in its most mature form—that was, as progressed in Paris around 1750—conquered most of Europe and has been imitated or copied in the mid-20th century. The model owes such popularity to a combination of leisure and charm. The seat suits to the human body and permits a relaxed seated position. The back is bow-shaped, the legs curved. Normally the seat and back are upholstered, and there are small upholstered pads covering the armrests. Smooth transitions made between seat frame, legs, and back disguise all the joints, which are stable, constructed on craftsmanlike principles in spite of the absence of stretchers between the legs.

French Rococo chairs and imitations thereof are made from wood of rather thick measurements; but each member is deeply molded, all superfluous wood has been cut away, and more upmarket designs would be further embellished with very delicate and decorative engravings. The wood might be varnished, stained, painted, or gilded. Silk damask or tapestry should be used for any upholstery on the seat, back, and armrests; canework is in some cases used as an alternative to upholstery.

English chairs from the 18th century were more varied in style than the French. The French manner for stylistic uniformity, which came from the aristocratic circles in Paris and Versailles over 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 popularised and was widely distributed throughout the world.

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

In cheaper 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.

After World War I, the Bauhaus school in Germany became a creative centre for revolutionary thinking, resulting, for example, in tubular steel chairs designed by the architects Marcel Breuer, Ludwig Mies van der Rohe, and others. During World War II, the aircraft industry accelerated the development of laminated wood and molded plastic furniture. The dominant chair forms of this period go back to designs by Alvar Aalto, Bruno Mathsson, and Charles and Ray Eames. Rapid technical developments, in conjunction with an ever-increasing interest in human-factors engineering, or ergonomics, hint that completely new chair forms will probably be evolved in the future.

Fundamentally, bookkeeping grants two kinds of information: (1) the current value, or equity, of the enterprise and (2) any changes in value—profit or loss—taking placement in the enterprise over a particular time.

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

Evidence of financial and numerical record charts have been uncovered for nearly every nation with a commercial history. Records of business contracts were found in the archaelogical digs of Babylon, and accounts for both farms and estates have been kept in ancient Greece and Rome. The double-entry method of bookkeeping began with the furthering of the enterprising republics of Italy, and instruction manuals for bookkeeping were created in the 15th century in various Italian cities.

Within 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 factual financial books a necessity. The history of bookkeeping, in fact, resembles the ancestry of commerce, industry, and government and, in part, helped in forming it. The worldwide spread of industrial and commercial activity called for greater professional decision-making methodology, which then demanded more sophistication in the selection, classification, and presentation of information, increasingly with the aid of computers. Taxation and government legislation became more detailed and resulted in higher need for information; enterprising firms had to have available information to list with their income tax, payroll tax, sales tax, and other tax reports. Governmental agencies and educational and other nonprofit institutions also become larger, and the requirement for bookkeeping for their inner operations became higher.

While bookkeeping methods can be very multifaceted, all are based on two types of books used in the bookkeeping procedure—journals and ledgers. A journal should have the daily transactions (sales, purchases, and such), and the ledger has the record of individual accounts. The daily records in the journals are put in the ledgers.

At the end of every month, as a general rule, an income statement and a balance sheet are constructed from the trial balance posted from the ledger. The point of the income statement or profit-and-loss statement is to give an analysis of the changes that took place in the enterprise equity as a result of the transactions of the period. The balance sheet shows the financial position of the business at a particular day taken from 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 trend to get back to the ‘eyeball-to-eyeball’ type of confrontation of the man in the Sopwith Camel. The pre-eminent Western fighter, the McDonnell Douglas F-4 Phantom, was rebuilt with an internal gun, a rapid-fire 20 mm (0.79 in) cannon with six barrels firing up to 6,000 rds/ min, and a slatted wing to pull tighter turns in combat.

New small fighters appeared, such as the General Dynamics F-16, which, although bigger and heavier than any single-engined fighters of World War II, are nevertheless small and light by comparison with such impressive machines as the Grumman F-14 Tomcat, McDonnell Douglas F-15 Eagle, and MiG-25 Foxbat, The RAF’s next interceptor, the ADV (Air-Defence Version) of the Panavia Tornado, is a careful midway compromise, smaller than the three monsters just listed, but with two engines, long range, powerful radar, and extremely effective Skyflash missiles.

Modern interceptors defend vast blocks of airspace up to 160 km (100 miles) in radius, with powerful radar able to look down at the surrounding land and water and spot low-flying intruders trying to slip through the defences unnoticed. Their task is eased by the presence of special surveillance, early-warning, and AWACS (Airborne Warning and Control System) aircraft, with enormous radars and sophisticated command and control systems to manage all a nation’s defences in the most efficient way.
