JAMES WATT THE INVENTION OF STEAM
ENGINE
James Watt
(19 January 1736-25 Agustus 1819) was an inventor who developed the steam
engine that became the basis of the Industrial Revolution.
James Watt was born on January 19, 1736 in Greenock, a seaport town on the Firth of Clyde, Scotland. His father is a ship owner and contractor, while his mother, Agnes Muirhead, came from respectable and educated family.
Watt did not attend school regularly but more and more educated at home by his mother. He showed remarkable dexterity and talent to an exact science like mathematics, although Latin and Greek did not move him, he liked the legends and folklore of Scotland.
When she was 18 years old, his mother died and his father's health began to decline slowly, Watt traveled to London to continue the study on the manufacture of instruments and equipment for one year, then returned to Scotland with the aim of making your own instrument-making business. But because he did not complete his seven-year study as apprentices (students who work while studying), an application to open a business is hampered, though at that time there has been no mathematical instrument maker and equipment in Scotland.
Assisted by three professors at the University of Glasgow, James Watt finally given the opportunity to open a workshop (garage) in a small university.
Four years after opening his shop, James Watt began to experiment with steam after his friend, Professor John Robison, got him interested in the machine. At that time, Watt had never operated a steam engine, but he still tried to make a model of the machine. Although it failed, he continued his experiments and began to read what can be read. He then separately discovered the importance of thermal energy generated and absorbed by each region to understand more about the machine. in 1765 he managed to make a model of a machine that can work well.
In recognition of his services for the development of the steam engine triggered the industrial revolution, and immortalized the name of Watt as a unit of energy used by the symbol W by the International System of Units (or 'SI') as we know it today.
THOMAS
ALVA EDISON THE INVENTOR OF THE LIGHT BULB
Thomas Alva Edison was the inventor of the U.S. and is one of the greatest inventors in history. Edison began working at a very young age and continued working until his death. During his career, Thomas Alva Edison had patented some inventions of 1093, including the electric light bulb and the gramophone, as well as film cameras. These three findings raise major industries for the power industry, recording and film that ultimately affect the lives of people around the world. He is also known as the inventor of applying the principle of 'mass production' for his discoveries.
Edison himself gained his expertise in the field of electricity and telegraphy (the telegraph for communication) in the teen years. In 1868, at the age of 21 years, he has developed and patented the discovery in the form of a recording telegraph machine.
The days of childhood, Edison only attended a formal school for three months, then all his education from his mother who taught Edison at home. Edison Edison mother teaches reading, writing, and mathematics. He also often gave and read books for Edison, among other books from authors such as Edward Gibbon, William Shakespeare and Charles Dickens.
Edison at age 12, earn revenue by selling newspapers and working papers, apples, and candy at a railway track. At that age, too, Edison had lost almost all hearing because of illness, the disease makes it a half-deaf. Edison once wrote in his diary: "I've never heard a bird sing since I was 12 years old."
At the age of 15, Edison, while still selling, bought a small printing press used to further mounted on a car trunk. Then he printed his own newspaper, Weekly Herald, which printed, edited and sold in the spot he was selling.
In the summer of 1862, Edison rescued a three-year-old boy who almost hit by a car. The father of a child who was saved was the head of the train station in place to sell. And as gratitude, head of the station taught Edison how to use the telegraph. After five months of studying the telegraph, Edison worked as a telegraph for 4 years. Nearly all the salary he earned was spent in building a wide range of laboratory and electrical equipment.
Edison was very happy to learn something and read the books there. Of all the learned, Edison applied the lessons in a way little experimenting in the laboratory. Edison lived in the laboratory, only sleep four hours a day, and eating of food carried by the assistant to the laboratory. Edison conducted experiments and experiments continued until his discoveries to be perfect. Perhaps a suitable word to describe the brilliance Edison: "Genius is 99% perspiration"
CONCLUSION :
Profiles of the two
figures above, it
can be concluded that in the experiment
or experiment if
done with hard work and sincere with what you want done then the effort will succeed and be a perfect fit with what is expected, although the experiment or the experiment was
always failures and
difficulties. In other words, the two men can be an
inspiration for us to always
strive in earnest and full of perseverance and hard work in doing
what we want to do. Hopefully we can be like they are always active in the work
and not easily
discouraged in the experiment.
