The Steam Engine By What are they? Steam engines are the first kind of engines to see a widespread use. They were used in the early locomotives, steam boats and factories. In fact they are still used to help run nuclear powerplants. When and by who were they invented and improved? The very first steam engine was built by Thomas Savery in 1698. However, it didn't turn any wheels, instead it pumped water out of coal mines. In 1712 Thomas Newcomen introduced an improved version of Savery's engine. James Watt improved it even further and later came up with an idea on how to use a steam engine to power something with wheels. Alright, but why are they important? Steam engines are veryveryvery important because it was the dominant source of power well into the 20th century. They actually were the moving force behind the Industrial Revolution. So no steam engines = no Industrial Revolution = Middle Ages that last approxima...
James Watt James Watt was born in Greenock on January 19 in 1736, the son of a ship's chandler. He worked in his father's shop and he developed an interest in trying to make things "work like clockwork". In his late teens he went to London to learn to be a "mathematical and philosophical instrument maker", and when he returned to Glasgow he got a job making instruments with Glasgow University, who gave him a place where to live and a workshop. In 1763 John Andreson asked him to repair an early steam engine he had bought. This early model, known as a Newcomen engine, was very unefective. The cylinder (where the piston was) had to be heated when steam was admitted, and then cooled again to condense the steam. This wasted a lot of time and fuel. Two years later, while walking through Glasgow Green, Watt hit upon the idea of condensing the steam in a separate place. This ...
1)Main machinery On a ship, the engine room, or ER, is the propulsion machinery spaces of the vessel. To increase the safety and damage survivability of a vessel, the machinery necessary for operations may be segregated into various spaces. The engine room is one of these spaces, and is generally the largest physical compartment of the machinery space. The engine room houses the vessel's prime mover, usually some variations of a heat engine - diesel engine, gas or steam turbine. On some ships, the machinery space may comprise more than one engine room, such as forward and aft, or port or starboard engine rooms, or may be simply numbered. 1.1)Main engine The engine room of a motor vessel typically contains several engines for different purposes. Main, or propulsion engines are used to turn the ship's propeller and move the ship through the water. They typically burn diesel oil or heavy fuel oil, and may be able to switch between the two....
TOPIC 3 James Watt James Watt was born in Scotland. James was a delicate boy and often suffered from severe headaches. That is why he could not go to school at the age when other children did. His mother taught him to read and his father taught him writing and arithmetic. He had a very good memory and a natural love of work. When his father saw that the boy liked to do things with his hands he brought him some tools from his workshop. For hours James would take his toys to pieces and the built new things from the parts to his own design. One day James noticed that, when the water in the kettle was boiling, the power of the steam moved the lid up and down, and when he held a cold spoon over the steam, it quickly turned back into drops of water. James was sent to a private school. He became good at languages as well as mathematics. In his spare time he began to make experiments. He managed to persuade an instrument-maker to take him as a...
The industrial revolution The Industrial Revolution, which took place from the 18th to 19th centuries, was a period during which predominantly agrarian, rural societies in Europe and America became industrial and urban. By mid-century, many people worked for small businesses or on farms, laboring in fields that would yield barely enough food to feed the family. New inventions and technology began to change that, however. Larger factories opened and produced new farm equipment, such as the steel plow and the tractor, which allowed farmers to cultivate bigger fields and produce more food that cost much less. Developments in the iron industry also played a central role in the Industrial Revolution. In the early 18th century, Englishman Abraham Darby (1678-1717) discovered a cheaper, easier method to produce cast iron, using a coke-fueled (as opposed to charcoal-fired) furnace. In the 1850s, British engineer Henry Bessemer ...
Topic No. 3 L.5 James Watt James Watt was born in Scotland in 1736. His father was a mathematical instrument maker. James was a delicate boy and often suffered from severe headaches. That is why he didn't go to school when the other children did, so his parents had to teach him. He liked mathematics and was fond of making things, so his father gave him some tools. James liked to take his toys to pieces and build new things to his own design. At the age of eighteen he decided to become a professional instrument maker. It was very hard to find a teacher. But finally he found an instrument maker in London who took him on as an apprentice. After a year he returned to Scotland and became a mathematical instrument maker. He also made musical instruments. He was asked to repair a small steam engine which was very primitive and used too much coal and a lot of steam was wasted. He ...

Trafalgar Square is a square in central London, England. With its position in the heart of London, it is a tourist attraction, and one of the most famous squares in the United Kingdom and the world. At its centre is Nelson's Column, which is guarded by four lion statues at its base. Statues and sculptures are on display in the square, including a fourth plinth displaying changing pieces of contemporary art, and it is a site of political demonstrations. The name commemorates the Battle of Trafalgar (1805), a British naval victory of the Napoleonic Wars. The original name was to have been "King William the Fourth's Square", but George Ledwell Taylor suggested the name "Trafalgar Square". The northern area of the square had been the site of the King's Mews since the time of Edward I, while the southern end was the original Charing Cross, where the Strand from the City met Whitehall, coming north from Westminster. As the midpoint between th...

1) INDIAN ROCK ART: A NATIONAL TREASURE IN DANGER Unrecognized, unprotected, this priceless legacy of primitive art has endured the ravages of nature only to fall victim to wanton destruction by ,,civilized" man. Like the huge stone statues of Easter Island and prehistoric cave paintings of Altamira and Lascaux, North American Indian rock art is surrounded by an atmosphere of mystery. Although examples of rock art exist at some 15000 sites in canyons, deserts, caves and river gorges. Nowadays, however, primitive rock art in the United States has become a new field of scientific study. Klaus F Wellmann wrote two books about rock art. He is a professor of medicine. Rock art represents the history of aboriginal Americans. In the most cases the art is an expression of ideas and way of life, ritual ceremonies, hunting, fighting. The pictures of people and animals are often strikingly lifelike and artistic. Many of these ancient relics have ...
ENGLISH LITERATURE Ancient Britain Lived on the British Isles in the 1st millenium. They most probably came from Eastern Europe and belonged to the Celtic race and also spoke Celtic. They were primitive hunters- gatherers, farmers. Some Celtic words are still used in modern English, however they are used mostly in place names. For example: · avon river · cumb valley · ford shallow place in the river Ancient Britons had their own religion and priests or druids and temples. In the year 55 BC Britain became a Roman province. Romans were highly developed and had their own language latin, which has also greatly influenced English. The military occupation of the Isles ended in 410 AD. The Romans eventually brought Christianity to Britain. Hadrian's wall on the border of Scotland and England. It began constru...

Tallinn 2013 Ott Speek Subject: English Geodesy Study group: GI-21b PETROLEUM PRESENTATION Petroleum (L. petroleum, from Greek: Πέτρα (rock) + Latin: oleum (oil) is a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. The name Petroleum covers both naturally occurring unprocessed crude oils and petroleum products that are made up of refined crude oil. A fossil fuel, it is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. This comes after the studies of structural geology (at the reservoir scale), sedimentary basin analysis, reservoir characterization (mainly in terms of porosity and perme...
