What is invention?



  Invention is produced for the first time
  through the use of imagination or ingenious
  thinking and experimentation. A famous
  quote is: "Necessity is the mother of
  invention." It means that the reason anything
  gets invented or improved is because of a
  need. New ideas produced inventions and
  changes.
   Invention is a highly creative process.

   “Discovery consists of seeing what
    everybody has seen and thinking what
    nobody has thought.”

   An open curious mind enables one to see
    beyond what is known. Inventors think
    outside of the box.
   Seeing a new possibility, a new connection or
    relationship can spark invention.

   Inventive thinking frequently involves
    combining elements from different realms
    that would not normally be put together.
    Inventors skip over the boundaries between
    distinctly separate territories or fields. Ways
    of thinking, materials, processes or tools from
    one realm are used as nobody had ever
    imagined in a different realm.
   Play can lead to invention. “All sorts of things
    can happen when you’re open to new ideas
    and playing around with things.” Childhood
    curiosity, experimentation and imagination
    can develop into a play instinct that is an
    inner need. Inventors feel the need to play
    with things that interest them, to explore, and
    this internal drive brings about novel
    creations.
   Inventors want to satisfy a need, they try to
    solve a problem or make something better.

   Inventing also takes insight. It may begin with
    questions, doubt.

Four Great Inventions of
Ancient China
China held the world's leading position in many
fields in the study of nature, from the 1st
century before Christ to the 15th century, with
the four great inventions having the greatest
global significance.
Papermaking, printing, gunpowder and the
compass - the four great inventions of ancient
China-are significant contributions of the
Chinese nation to world civilization.
Papermaking

China was the first nation who invented
paper. The earliest form of paper first
appeared in the Western Han Dynasty
(206BC-23AD), but the paper was
generally very thick, coarse and
u     n     e       v      e     n    .
In the Eastern Han Dynasty (25-220), an official named Cai
Lun made a new kind of paper from bark, rags,
fishnet and other materials. It was relatively cheap, light, thin,
durable and more suitable for brush writing. At the beginning
of the
 3rd century, the paper making
process first spread to Korea
and then to Japan. It reached
the Arab world in the Tang
Dynasty, and Europe in the
12th century. In the16th century,
it went to America by way of
Europe and then gradually
spread all over the world.
Printing
Yet block(雕版) printing had its drawbacks. All the
boards became useless after the printing was done and a
single mistake in carving could ruin a whole block. In
1041-1048 of the Song Dynasty (960-1279), a man named
Bi Sheng carved individual characters on identical
pieces of fine clay which he hardened by
a slow baking process, resulting in pieces
of movable type(铅字). When the printing was
finished, the pieces of type were put away
for future use. This technology then spread
to Korea, Japan, Vietnam and Europe. Later,
German Johann Gutenberg invented movable
type made of metal in 1440-1448.
Gunpowder

The invention of gunpowder had a close relationship
with the advanced ancient workmanship of smelting
industry. People began to know a lot of chemistry
knowledge about the nature of different mineral
materials during the process of smelting operation.
Although they failed to get what they were looking for,
they discovered that an explosive mixture could be
produced by combining sulfur, charcoal(木炭), and
saltpeter (硝石). This mixture finally led to the
invention of gunpowder although its exact date of
invention still remains unknown.
Gunpowder
Many historical materials indicate that gunpowder
first appeared before the Tang Dynasty (618-907).
The military applications of gunpowder began in the
Tang Dynasty. In the Yuan Dynasty (1279-1368),
the method of powder-making was introduced to
the Arab world and Europe, bringing a series of
revolutions to weapon manufacturing.
 Compass
Early in the Spring and Autumn Period (770-476BC), while mining ores
and melting copper and iron, Chinese people chanced upon a natural
magnetite that attracted iron and pointed fixedly north. In the Warring
States Period (206BC-23AD), after constant improvement the round
compass came into being. Referred to as a "South-pointer", the spoon-
shaped compass is magnetic. The circular center represents Heaven,
and the square plate represents Earth. The handle of the spoon points
south. The spoon is a symbolic representation of the Great Bear.
The plate bears Chinese characters which
 denote the eight main directions of north,
north-east, east, etc. This type of compass
has been scientifically tested and found to
 work well.
Compass
One of the first books to describe the
magnetic compass, Dream Pool Essays
(1086) by Shen Kuo in the Song Dynasty,
about 100 years earlier than its first record in
Europe.
Before its invention, navigators had to
depend on the positions of the sun, the
moon and the polestar for their direction.
The spread of the compass to Europe
opened the oceans of the world to travel and
led to the discovery of the New World.
Thomas Alva Edison was born in 1847 in
Milan, Ohio He grew up in Port Huron,
Michigan. In 1877, and died on Oct 18, 1931,
aged eighty- four. No other inventor has
approached the number of patents issued to
Thomas Edison, singly or jointly - 1093.
Among them, the most well known one may
be the phonograph(唱机)-a machine that
talked.
   To encourage people to think about the importance
    of his creation, Edison gave his own ideas for the
    most important uses of the phonograph:
   Recording music
   Recording the human voice to:
       make books for blind people
       teach people to improve their speech
       save voices of family members for future generations
       make clocks that told time
       Making toys for children. In 1894, Edison started
        making dolls with tiny phonographs inside.
Who is he?
   More than a cure for headaches and minor pain,
    aspirin has been clinically proven to work
    wonders for many conditions. People at risk of
    heart attack are advised to take an aspirin a day,
    and aspirin is used to prevent and treat stroke.
    Aspirin is also thought to be a drug for cancer,
    heart disease, stroke, and blindness. Studies
    have shown that long-term aspirin taking can
    reduce the risk of death from cancer by over
    40%. Today, over 70 million pounds of aspirin
    are produced annually around the world, and
    Americans consume more than 15 billion tablets
    per year.

Part C: The Camera Man
     Do you own a camera? Undoubtedly you
 do, and you probably use it often, too. Just
 slip the camera in your backpack pocket, and
 you're set to record your activities on film. But
 before 1888, you would have needed a
 wagon to carry all the necessary equipment
 just to take one photogragh. Early cameras
 were the size of microwave ovens! But
 Geroge Eastman changed the way the world
 took pictures.
    Born in upstate New York on July 12, 1854,
George Eastman was the youngest of three
children. His father died when George was a
young boy. He was forced to quit school at 14
and work to support his family. In 1874, he got
a job as a junior clerk at a bank for $15 a week.
        A friend introduced George to
photography when he was 24. George
loved taking pictures, but he didn't like the
complicated process. He worked for years
to invent something to replace the old
machine. When he succeeded, he started
a company to produce his "film", Kodak.
Then he worked on developing a simple
camera.
    When he introduced his camera in
1888, George coined the advertising
slogan, "You push the button, we do the
rest." People began buying the cameras,
and Kodak soon grew to be very large.
     George Eastman was also a great
philanthropist. He gave much of his fortune to
establish hospitals, clinics, universities,
museums and performing arts centers. When
he died in 1932 at the age of 77, an editorial
in The New York Times said he would be
remembered for giving generously for the
good of mankind. And, of course, for putting a
Kodak smile on the faces of people around
the world.
