In the last two centuries, new cultural discoveries nearly rewritten history. It was an exciting time, full of adventure and surprises. Around every corner there are new answers to questions that we have already answered imagine. And these breakthroughs, not so bright lights, such as the impact of ancient Chinese inventions on modern life. When we were ten of the greatest inventions and innovations of ancient China, you will be surprised at their influence on the latest technology.

1. Paper. Paper, as we know it was in China around the year 105 After I used Attempts, silk, bamboo sticks and skins, Cai Lun came with his own idea. After mixing mulberry bark, rags, wheat stalks and other things, a mash up. This pulp was pressed into disks and dried, is a crude form of paper. Paper was such an important invention that the process that it was a jealously guarded secret. The secret was safe until the seventh century, when the art in India.

2. The printing press. Before Johann Gutenberg invented the printing press in the 1440's, China, a type of printing press between 206 BC and AD 45. It was with stone tablets, a "friction" of the famous Buddhist and Confucian texts. Next came the pressure-block Sui Dynasty. In block printing, images and words are engraved on boards, smeared with ink and pressed on paper. Later, movable type printing presses were introduced. According to the authors of the Ancient Inventions "by AD 1000, paged books in the modern style had Scrolls - a good 450 years before Gutenberg."

3. The first book. By the early introduction of the printing press, China also claims the first book. In 868, nearly six hundred years before the Gutenberg Bible, the earliest known book was printed. By the end of the Tang dynasty, China had bookstores in almost every city.

4. Paper money. While you now prefer a lot of money instead of coins, it was not always the case. The idea of paper currency was first attempted under Emperor Han Wu Ti (140-87 BC) after the war had drained the treasury. He notes the Treasury, Wörth, in exchange for 400,000 copper coins. Instead of paper, the Emperor used the skin of the white deer. But the creature was so rare that the idea soon lost appeal. In the first 800 is the idea again to deter highway robbers. In 812, the government printing money. By the year 1023, money had an expiration date and was already plagued by inflation and counterfeiting. Almost six hundred years later, paper money, headed west, first in Sweden in 1601.

5. The Abacus. Long before Texas Instruments, the first computer was in the works. The Abacus data from the year 200 B.C. It is a very advanced tool with a simple design. Wood is crafted into a rectangular frame with rods, the base upwards. About 2 / 3 's of the base, a divider on the Framework, also known as the counting bar. On each of the rods are beads. All of the above beads counting bar equal five. The bottom is the same. The rows of rods are read from right to left. The most popular bar on the right side holds the position over the next ten place, then the hundred's, and so on. While its design may be complex, there are some Chinese now so skilled that they solve difficult math problems faster than someone with a computer!

6. The Decimal System. In the West, the decimal system appeared recently. His First Instance took the view in a Spanish manuscript from approximately 976th But the first true example goes much further. In China, the inscription dates from the 13th Century BC, "547 days" was described as "five hundred plus four decades plus seven days." The Chinese are probably the decimal system, because their sign language depended (like pictures) instead of an alphabet. Each number has its own unique character. Without the decimal system, the Chinese had a terrible time to remember all these new characters. Through the use of units, tens, hundreds, etc., the Chinese saved time and effort.

7. The mechanical clock. In the year 732, a Buddhist monk and mathematician, invented the first mechanical clock. He called it "Water-Driven Spherical bird's-eye map of the sky." Like earlier clocks, water gave it, but the movement cased machines. But after a few years ago, corrosion and frost have taken its toll. It was not until 1090, when astronomer Su Sung designed his mechanical marvel "Cosmic Engine", which is a reliable timepiece was. Created for Emperor Ying Zong, this clock had a tower over 30 meters high. It is that the machines, among other things caused wooden puppets to pop from one of the five gates at regular intervals throughout the day. (Similar to the modern idea of a cuckoo clock.) The entire system was powered by a giant waterwheel. The clock ran until 1126, when it was dismantled by the conquest and Tatars in Beijing for another several years. The first reference clock in the Western history was in 1335, in the Church of St. Gothard in Milan.

8. The Planetarium. A planetarium is a large enclosed space, the stars and constellations on the inside. Orbitoscope was the name of the first projection planetarium. It was in 1912 in Professor Basil E. Hinderman. But again, China is the mother of invention. The first planetarium is due to the design of an early emperor. As one source stated that an astronomer named Jamaluddin a planetarium during the Yuan Dynasty (1271-1368), together with a perpetual calendar and other important astronomical instruments.

9. The seismic sensors. The first earthquake sensor was also an interesting piece of art. It was a bronze cylinder about 8 feet around, with 8 dragons high above 8 open-mouthed frogs. In the mouth of each dragon rested a bronze ball. If an earthquake, a pendulum with an inside of the cylinder would swing. He knocked the ball from the mouth of the dragon and the frog in the mouth. The frog's back was then before the direction of the center of the quake. Chang Heng invented it in the year 132 (during the Han Dynasty), almost 600 years before the first western sensor was in France. Later, in 1939, Imamura Akitsune new invention and actually effective.

10. The helicopter rotor and propeller. While the ancient Chinese did not invent the helicopter, in their facility. In the 4th Century AD, they invented a toy called the "Bamboo Dragonfly". You've probably seen the prices at local fairs or carnivals. It was a toy top, with a base like a pencil and a small helicopter-like blade at the end. The top was wrapped with a cord. If you pulled the cord, the blade would spin around and soar into the air. This toy was designed by Sir George Cayley in 1809 and played a role in the development of modern aviation. It was not until the early 1900's that the first helicopter took flight.

Sometimes it's a mind blowing, which is to realize that what seemed to be modern ideas or inventions that are much older than we thought. And it is likely that there are more inventions to be discovered. More historical changes are made. In the conclusion of the greatest inventions of the past 2,000 years, Jared Diamond also adds, referring to the changing view of history and its inventors, "So, forget those stories about inventor, genius, the perceived need of society, they one hand, and thus the world. There's never been such a genius ... ... .. If Gutenberg does not develop, the better alloys and colors used in early printing, some other contemporary tinker with metals and oils would have done ... ... give Gutenberg some of the credit - but not too much. "

Questions:

1. Choose one of the inventions mentioned. Explain how different the world would be if it has not yet been invented.

2. Why do you think that there is such a large space of time between the Eastern and Western dates of the invention?

3. What are two other inventions, from the ancient China? Research and find out if the idea was introduced to Western culture.
