technology quotes

It has become appallingly obvious that our technology has exceeded our humanity.
Albert Einstein 


The first rule of any technology used in a business is that automation applied to an efficient operation will magnify the efficiency. The second is that automation applied to an inefficient operation will magnify the inefficiency.
Bill Gates

Technology is just a tool. In terms of getting the kids working together and motivating them, the teacher is the most important.
Bill Gates 



The world is very different now. For man holds in his mortal hands the power to abolish all forms of human poverty, and all forms of human life.
John F. Kennedy 



 Soon silence will have passed into legend. Man has turned his back on silence. Day after day he invents machines and devices that increase noise and distract humanity from the essence of life, contemplation, meditation.
Jean Arp



One machine can do the work of fifty ordinary men. No machine can do the work of one extraordinary man.
Elbert Hubbard 


The typewriting machine, when played with expression, is no more annoying than the piano when played by a sister or near relation.
Oscar Wilde

what is technology and why is it important

what is it exactly?

over the years, technology has changed as a one meaning term to a term with multiple meanings such as:
Objects:
Tools, machines, instruments, weapons, appliances - the physical devices of technical performance
Knowledge:
The know-how behind technological innovation
Activities:
What people do - their skills, methods, procedures, routines
Process:
Begins with a need and ends with a solution
Sociotechnical System:
The manufacture and use of objects involving people and other objects in combination
 
Technology has very interesting characteristics as well:

It is Related to Science.
High technology industries are examples of the relationship of technology and science. Not very much technology can be classified as applied science. Technology is marked by different purposes, different processes and different relationship to established knowledge and a particular relationship to specific contexts of activity.

It Involves Design
At the center of technology lies design. That design is the heart of engineering is stated by the requirement that all degree engineering courses should embody it. The design process in technology is a sequential process which begins with the perception of a need, continues with the formulation of a specification, the generation of ideas and a final solution, and ends with an evaluation of the solution.

It Involves Making
The motivating factor behind all technological activity is the desire to fulfill a need. It's because of this that all designs should be made or realized if the need is to be truly fulfilled, the design is to be legitimately evaluated, and the design activity is to have been purposeful and worthwhile.

It is Multidimensional
technology involves technologists in performing many functions, such as working with others, operating within budgets, persuading decision makers, communicating to clients and working to deadlines.

It Is Concerned With Values
Technology is informed by values as well. Value decisions may be called for not only in relation to the specific design criteria, but also in relation to the right or wrong of a particular solution in ethical terms.

It is Socially Shaped/Shaping
Technological enterprises are determined by social interests. Of the new technologies available at any time, only a few are developed and become widely implemented. In this way technology is shaped by society, by consumer choice. yet it could also be argued that technology shapes society.


why is it important?

Technology brings importance everywhere and anywhere. in schools, technology is used to be able to teach more students and teach much easier via projector and to help give visual notes for future study. technology is also used in many ways for entertainment and fun. The video game console and the television are great examples of entertainment in technology. Another huge and important use of technology is transportation such as airplanes, cars, trucks, trains and much more these are all used in our favor to get to places much faster and efficient.

the boiler cylinder and piston

Boiler, cylinder and piston: AD 1704-1712
Two metalworkers, Thomas Newcomen, and John Calley, are making good progress in some potentially very profitable experiments. They know the high cost of the horse-driven pumps that raise water from the copper and tin mines. So they are working on a steam pump. Though unaware of this, they are combining two elements pioneered separately, Papin's piston and Savery's separation of the boiler from the cylinder.
In Newcomen's engine the piston is attached by an iron chain to one end of a beam which seesaws on a central pivot. At the other end of the beam another chain leads down to the water-pumping mechanism. Steam released from the boiler into the cylinder pushes up the piston. When the cylinder is full of steam cold water poured on the outside condenses the steam and creates the vacuum. But in this case, instead of directly sucking up water, the vacuum causes the piston to descend in the cylinder. This activates the pump at the end.
As so often in the advance of science and technology, an accident provides Newcomen with the refinement which brings his pump up to an economic speed. A flaw develops in one of the seams of his cylinder. As a result some cold water, intended only to flow down the outside, gets into the cylinder when it is full of steam. It creates a vacuum so rapid and so powerful that it snaps the chain attaching the piston to the beam. With this event another lasting feature of the steam engine is discovered. In all Newcomen's developed engines, which soon start work in England's mines, the steam is condensed by a jet of cold water injected into the cylinder.
The first of Newcomen's working engines is installed in 1712. It operates successfully for thirty years, as the first of many in the mining districts of Britain. Even with Newcomen's improvements, these machines are suitable only for the slow relentless work of pumping in the mines.

Iron Bridge, Tools and Guns

Ironbridge: AD 1779

In 1779 the world's first iron bridge, which reached over 100 feet, is erected for Abraham Darby. But in this new technology little time need be spent in assembling the parts. The lightness of the structure strikes all observers. It still stands to this day.

Machine tools, gun barrels and cylinders: AD 1774-1800

John Wilkinson has been building up a lucrative arms trade. In 1774 he invents a machine, powered by a water wheel, which can drill with unprecedented accuracy through the length of a cast-iron cylinder to create the barrel of a cannon. It is a turning point in the development of machine tools. James Watt realizes that Wilkinson's new machine is capable of the precision required for an efficient steam-engine cylinder. In 1775 Wilkinson delivers the first of the cylinders to other countries. Instead of the usual pumping of water, it is to undertake a more sophisticated role - working the bellows which pump air into one of Wilkinson's blast furnaces of molten iron. The owners of the mills and mines of the Industrial Revolution have many tasks to which a source of mechanical power could be usefully applied. The reports are good. By the time Watt's patent expires, in 1800, more than 500 engines have been installed around the country and further. The increased efficiency of the new engines, enables Boulton and Watt to charge by a novel and very profitable method. The machines are provided and installed free, and customers pay a royalty of one-third of the amount saved on fuel. From 1783 the saving is even greater, because in that year Watt puts on the market another major innovation - his double-acting engine.

The Millennium Clock

A millennium clock: AD 1746

In 1746 a French clockmaker named Monsieur Passemont makes a clock which is the first in the world to be able to take account of a new millennium. Its dials can reveal the date of the month in any year up to AD 9999. It is a long case clock, in an ornate baroque casing that holds a mechanism having more than 1000 interconnecting wheels and cogs. As they turn at their different speeds with each swing of the pendulum, they cope with the complexities of the Julian calendar. Thus, for example, one large brass wheel has the responsibility of inserting February 29 in each leap year. This wheel takes four years to complete a single revolution. When it has come full circle, it pops in the extra day. Louis XV buys the clock in 1749, three years after its completion. It is still ticking away two and a half centuries later in the palace of Versailles. The minutiae of daily time-keeping are also adjusted by hand, but Monsieur Passemont's masterpiece requires no assistance in making a significant change in the first digit of its year display.

Domestic Clocks

Domestic clocks: 15th century AD

After the success of the clocks in Europe's cathedrals in the 14th century, and the introduction of the clock face in places such as walls, kings and nobles naturally want this impressive technology at home. The first domestic clocks, in the 15th century, are smaller and simpler versions of the cathedral clocks which are powered by hanging weights. It shows the time to the great man's family and household by a single hand working its way round a 12-hour circuit on the clock's face. But before the middle of the 15th century a development of great significance occurs. The earliest surviving spring-driven clock dates from about 1450. By that time clock makers have not only found out how to transmit power to the mechanism from a coiled spring. They have also devised a simple solution to the problem inherent in a coiled spring which steadily loses power as it uncoils. The solution to this is the fusee. The fusee is a cone, bearing a spiral of grooves on its surface, forming part of the axle driving the wheels of the clock mechanism. The length of gut linking the drum of the spring to the axle is wound round the fusee. It lies on the thinnest part of the cone when the spring is fully wound and reaches its broadest circumference by the time the spring is weak. Increased leverage counteracts decreasing strength. These two devices make possible clocks which stand on tables, clocks which can be taken from room to room, even clocks to accompany a traveler in a carriage. Eventually, they make possible the pocket watch as well.

The Steam Pump

Steam pump: AD 1698-1702

Thomas Savery, in 1698  obtains a patent for an engine to raise water by the impel-lent force of fire. It turns out to be the world's first steam engine. Originally designed purely as a pump, it has no piston but relies on the power of a vacuum. A metal cylinder is filled with steam from a boiler. Cold water is then poured over the outside, condensing the steam within and creating a vacuum which sucks water up through a pipe at the base. When the cylinder is full of water, the valve from below is closed. Steam is again introduced, forcing the water out of the cylinder through another valve. With the cylinder again full of steam, the process is repeated. As it turns out, the maximum levels of pressure and vacuum achieved by Savery cannot lift water more than about twelve yards. Instead he finds his main customers among progressive country landowners, who are attracted by being at the cutting edge of technology. They use Savery's pumps to raise water for their houses and gardens.

The First Miners, Yoke and Harness and the Plough and Draught Animals

THE FIRST MINERS

By 4000 BC deep shafts are cut into the hillside at Rudna Glava, in the Balkans, to excavate copper ore. This robbing of the earth's treasures is carried out with due solemnity. Fine pots, that hold produce from the daylight world, are placed in the mines as a form of recompense to propitiate the spirits of the dark interior of the earth. By about 3800 BC copper mines are also worked in the Sinai peninsula. Crucibles found at the site reveal that smelting is carried out as part of the mining process.

Yoke and harness: from 4000 BC

The harnessing of draught animals is a major technological advance in agriculture as well as transport. The ox is the first to be harnessed, conveniently provided by nature with a fleshy hump above the shoulders. A yoke that is laid in front of the ox will remain in place even when a heavy load is pulled. A lighter yoke is sometimes attached to the horns as well. Oxen are used to drag heavy objects or loaded sledges by about 4000 BC. The camel has an even more convenient hump however. Its height makes it less suitable for draught purposes than the ox, but it is used in Asia and north Africa for wagons and for plowing. But harnessing the horse proves problematical. A traditional yoke can only be kept in place on a horse by passing thongs in front of its chest. However these must be placed very carefully because they must pass in front of the animal's windpipe. The heavier the weight it attempts to pull, the less air it will breathe. For many centuries, horses are not very effectively used as draught animals. The solution, discovered in China by the 5th century AD, is to provide a firm collar, fitting round the neck and shoulders of the animal to hold the weight. These collars reach Europe by the 9th century AD, causing the horse to become the main draught animal of the region for both ploughing and haulage.


The plough and draught animals: from 3000 BC

The plough is the first implement for  a source of power other than the use of ones own muscles. When planting seeds, it is needed to break up the ground. In the early stages of agriculture, hacking and scraping with a suitably pointed implement would be the way to go. But a useful furrow can more easily be achieved by dragging a point along the surface of the ground. The first ploughs have a sharp point of timber projecting downwards at the end of a long handle. In the light soil of Egypt and Mesopotamia, where ploughing is first undertaken, a simple pointed implement of this kind is needed to break up the earth and form a shallow trench. A plough can be dragged by a couple of men. But the use of draught animals such as oxen, from at least 3000 BC, greatly speeds up the process. In northern Europe, with heavier soil, this type of plough is very ineffective. A more elaborate machine is then developed by the Celts in the 1st century BC where a sharb blade cuts into the earth and an angled board turns it over to form a furrow.

The Loom

Loom: from 6000 BC

Weaving of cloth requires a loom a structure which will hold taut the vertical threads the warp. While the weaver snakes each horizontal thread in and out to form the weft. When the threads of the weft are pressed down tight. This forms a solid mesh with the warp, a section of the cloth at the bottom of the loom is complete. A pattern is achieved by varying the colour of the threads in warp and weft. The earliest known evidence of a loom comes from Egypt in about 4400 BC. But some method of supporting the warp exists from the beginning of weaving. The threads must either be suspended and held taut by a weight at the bottom or else must be stretched in the rigid frame of a conventional loom.

Early Technology and Its Tools

Stone tools of early technology

The human discovery that round nodules of flint can be split and chipped to form a sharp edge is extremely ancient. Tools made in this way have been found in Africa from about 2.5 million years ago, the earliest known examples have been discovered at Gona, in the Awash Valley in Ethiopia. Gradually, over the years, new and improved techniques are developed for striking off slivers of stone. Variations in the flints found with fossil remains, differing both in the method by which flakes are chipped from the core, and in the range of shapes created, are used by anthropologists as one way of assigning human skeletal remains to specific groups or divisions of the stone age. In the earliest periods a tool is usually made from the core of the flint, resulting in an instrument that can be used in a fairly rough manner for either cutting or scraping. Hundreds of thousands of years later, craftsmen have become skilled at forming the flakes themselves into implements of various kinds, producing specialist tools for cutting, scraping, gouging or boring, as well as sharp points for arrow and spear heads. These sophisticated stone tools make it possible to carve materials such as antler or bone to create even sharper points or such as hooks or needles.
