INVENTION

Innovation is the act of introducing new ideas and methods to improve the old ones. It is an important element which effects to the development of a country. It is changing our daily life also. People are always active and creative to brainstorm to find new things and apply them in many fields. We can see innovation in science, economy, education, politic, culture and other areas. In my opinion, Innovation is a big topic and we have limited time so I just focus on one of kind of it, INVENTIONS.
Just have a quick look at some things around you, you can realize there are many inventions which have given you a lot of advantages like convenience and comfort in daily life. Image how your life would be if we did not have any invention!!
Great inventions around the world were created and have been applied to help us to reach the modern life. Women find it comfortable and easy to balance the time to arrange their work in office and their housework, taking care of their babies. Men have much more time for their families and hobbies.
Inventions have been in a lot of daily fields such as communication, transportation, entertainment, food and others. How about our life if there were no electricity, no lights, no TVs, no internet, no laptops, no high-tech machines? How could you communicate with others easily and timely without telephones or mobile phones?
How long would it take you to move to other places without means of transport like motorbikes, cars, ships or planes? When you get ill but no medicine, what would happen? There are a lot of questions like this which you spend all life to answer. Close your eyes in 30 seconds and image how you could manage you life without inventions, you will value its importance.

Pre-electrical Lamps
The first lamp was invented around 70,000 BC. A hollow rock, shell or other natural found object was filled with moss or a similar material that was soaked with animal fat and ignited. Humans began imitating the natural shapes with manmade pottery, alabaster, and metal lamps. Wicks were later added to control the rate of burning. Around the 7th century BC, the Greeks began making terra cotta lamps to replace handheld torches. The word lamp is derived from the Greek word lampas, meaning torch.

Oil Lamps
In the 18th century, the central burner was invented, a major improvement in lamp design. The fuel source was now tightly enclosed in metal, and a adjustable metal tube was used to control the intensity of the fuel burning and intensity of the light. Around the same time, small glass chimneys were added to lamps to both protect the flame and control the flow of air to the flame.

Ami Argand, a Swiss chemist is credited with first developing the principal of using an oil lamp with a hollow circular wick surrounded by a glass chimney in 1783.
Lighting Fuels
Early lighting fuels consisted of olive oil, beeswax, fish oil, whale oil, sesame oil, nut oil, and similar substances. These were the most commonly used fuels until the late 18th century. However, the ancient Chinese collected natural gas in skins that was used for illumination.
In 1859, drilling for petroleum oil began and the kerosene (a petroleum derivative) lamp grew popular, first introduced in 1853 in Germany. Coal and natural gas lamps were also becoming wide-spread. Coal gas was first used as a lighting fuel as early as 1784.
Gas Lights
In 1792, the first commercial use of gas lighting began when William Murdoch used coal gas for lighting his house in Redruth, Cornwall. German inventor Freidrich Winzer (Winsor) was the first person to patent coal gas lighting in 1804 and a "thermo-lampe" using gas distilled from wood was patented in 1799. David Melville received the first U.S. gas light patent in 1810.
Early in the 19th century, most cities in the United States and Europe had streets that were gaslight. Gas lighting for streets gave way to low pressure sodium and high pressure mercury lighting in the 1930s and the development of the electric lighting at the turn of the 19th century replaced gas lighting in homes.

FUNNY STORY:
THE BOM AND THE PILOT
Three people were on a plane. One said to the pilot, "I have a glass bottle. What do I do with it?" The pilot told him to throw it out the window. The second one asked the same question and the pilot also told him to throw it out the window. The third one asked the pilot, "I have a bomb. What do I do with it?" The pilot told him to throw it out the window. When they landed they met a man crying. When asked why he was crying, he replied, "Because I got hit in the head with a glass bottle. They met a woman who was crying for the same reason. Then the met a man laughing. They asked him why he was laughing and he replied, "Because I walked by a building and farted. Then the building blew up.
