The story of scientist Zhang Heng? Hurry Rush 30

When Zhang Heng was very young, Xiao Zhang Heng was his grandmother's little tail, no matter how much grandma walked to **, there would always be the shadow of Xiao Zhang Heng behind. He always pestered his grandmother to tell him stories. The old man seems to have endless stories to tell, and he likes this smart grandson very much, so as long as Xiao Zhang Heng asks to listen to the story, his grandmother will tell him it.

Among these stories, Xiao Zhang Heng's favorite is the legend of the Big Dipper and the moon, he always looks up at the blinking stars in the sky, while listening to his grandmother, and from time to time asks his grandmother: Why don't the stars fall like apples? Are the stars afraid of rain?

Of course, his grandmother did not come up to the question of his clever grandson, which made him feel more and more that there would be countless treasures in the vast night sky, and at the same time, he also planted countless curious question marks in his young heart. Unable to get an answer from his grandmother, Xiao Zhang Heng eagerly read a book, hoping to find the answer he wanted from the book.

When he was ten years old, his grandmother and father died. Uncle sent Zhang Heng to study in the library. He knew how difficult it was for him to study, so he worked very hard.

Soon, Xiao Zhang Heng began to compose poems. His poems are often praised by his teachers. In order to increase his knowledge, Xiao Zhang Heng read a wide range of books.

One day, he saw a book called "Osprey Crown" and was fascinated by the four sentences in the book that determine the seasons according to the Big Dipper. Since then, he often looks up at the starry sky and observes the changes of the Big Dipper, and over time, he finds that the Big Dipper is revolving around a center, once a year. He said to himself:

Ah, I finally get it'The Big Dipper shifts'What's going on! Due to his diligence and inquisitiveness, as he grew up day by day, Zhang Heng's knowledge became richer and richer, and he finally became a scientist.

Suddenly, the ball of steel in the northwest direction of the instrument fell and fell into the mouth of the toad beneath the instrument. Who. A few days later, the Longxi poster galloped to Beijing day and night to report the landslide of Longxi **, Erjun (Longxi is just northwest of Luoyang.

It's a thrilling story.

Zhang Heng (78-139), the word Pingzi. Han rent split clan, Nanyang Xi'e (now Shiqiao Town, Nanyang City, Henan), one of the five saints of Nanyang, and Si Sui Bei Ma similar.

Yangxiong and Ban Gu are also known as the four masters of Hanfu. He was a great astronomer, mathematician, inventor, geographer, and writer during the Eastern Han Dynasty in China.

In the Eastern Han Dynasty, he successively served as Langzhong, Taishiling, Shizhong, and Hejian. Zhang Heng has made outstanding contributions to the development of Chinese astronomy, mechanical technology and science, invented the armillary sphere and the geodynamic instrument, and is one of the representatives of the armillary theory in the middle of the Eastern Han Dynasty. It was denied by later generations as "Wood Saint" (Ke Sheng).

He is the author of "Lingxian" and "Armillary Sphere Annotation", etc., and his mathematical works include "Theory of Calculation", and his literary works are "Erjing Fu".

Returning to the field" and so on. "Sui Shu Jing Ji Zhi" has 14 volumes of "Zhang Heng Collection", which has been lost for a long time. Zhang Pu of the Ming Dynasty compiled the "Zhang Hejian Collection", which was included in the "Collection of One Hundred and Three Families of the Six Dynasties of the Han and Wei Dynasties".

In his later years, he entered the court as Shangshu due to illness, and died in the fourth year of Yonghe (139) at the age of sixty-two. Northern song dynasty.

When he was posthumously named West Obo.

3 people. That lightning.

Loving food is my attitude to life.

Concern. Thank you for your interest.

1. Invent the ground motion instrument.

In 132 A.D. (the first year of Yangjia), Zhang Heng invented the earliest geodynamic instrument during the appointment of Taishi Ling, which was called the Houfeng geokinetic instrument. According to the "Book of the Later Han Dynasty, the Biography of Zhang Heng" records: the geodynamic instrument is cast with fine copper, with a diameter of eight feet, the top cover is protruding, the shape is like a wine bottle, and it is decorated with the vertical circle of turtles, birds and beasts in the seal of the mountain.

There are big pillars, and there are eight roads to close, and the machine is closed. It has eight directions, each with a dragon with a copper bead in its mouth, and a toad corresponding to each dragon.

If there is a ** occurrence on either side, the copper beads contained in the dragon's mouth in the direction will fall into the mouth of the toad, so that the direction of the occurrence of ** can be measured. After testing, it was set up with the system, and Yu Ma was like a god, which has not been done since there were books to record it. Once a dragon machine, the ground did not move, the scholars of Luoyang blamed the lack of faith, a few days later, the messenger came, and sure enough, it happened in Longxi**, and everyone obeyed its wonder.

Since then, the imperial court has ordered historians to record the place where the earth movement took place.

In the first three years of Emperor Zhang Hengzhang's founding (78 AD), he was born in a dilapidated bureaucratic family in Shiqiao Town, Xi'e County, Nanyang County (now Shiqiao Town, fifty miles north of Nanyang City, Henan Province). His grandfather, Zhang Kan, was a local official and served as the Taishou of Shu County and the Taishou of Yuyang. When Zhang Heng was a child, his family had declined, and sometimes he had to rely on the help of relatives and friends.

It was this kind of impoverished life that enabled him to come into contact with the working masses of the lower strata of society and some realities of production and life, which brought a positive impact on his later scientific creation. In mathematics, geography, painting, and literature, Zhang Heng showed extraordinary talent and extensive knowledge. Zhang Heng is one of the representatives of the Hun Tian Theory in the middle of the Eastern Han Dynasty; He pointed out that the moon itself does not emit light, and that moonlight is actually a reflection of daylight; He also correctly explained the causes of lunar eclipses and recognized the infinity of the universe and the relationship between the speed of the planets and their proximity to the Earth.

Zhang Heng [1] observed and recorded 2,500 stars, created the world's first leaky armillary sphere that can perform celestial phenomena more accurately, the first instrument to test the first - the wind and ground motion instrument, and also manufactured a guide car, an automatic memory drum car, a wooden bird that flew several miles, and so on. Zhang Heng is the author of a total of 32 scientific, philosophical and literary works, including astronomical works such as "Lingxian" and "Lingxian Diagram". In order to commemorate Zhang Heng's exploits, people named a crater on the far side of the moon "Zhang Heng Crater", and the asteroid 1802 was named "Zhang Heng Star" Guo Moruo, a famous Chinese writer and historian in the 20th century, commented on Zhang Heng as:

Such a well-rounded figure is rare in world history, and it is admired for thousands of years. Later generations called Zhang Heng a wooden saint.

At night, the sky is full of stars like countless pearls scattered in a jasper plate, and a child sits in the courtyard. Leaning on grandma. Raise your head and point to the sky and count the stars.

One, two, all the way up to hundreds. Grandma smiled and said, "Silly boy, I'm counting the stars again."

So many stars, twinkling and twinkling, all eyes are dazzled. Can you count them? The child said:

Grandma, you can see it. You can count them. The stars are moving, not chaotic.
