Hua Luogeng's story.

Mathematician Hua Luogeng has unique insights in the study of applied mathematics, and he uses mathematical knowledge to solve practical problems in mass production, and is a great scientist in China.

When he was in elementary school, Hua Luogeng was very fond of mathematics. In addition to reading his own textbooks, he often borrowed his teacher's books to read. Once, he borrowed a magazine from his teacher and looked at it with relish.

He ran up to the teacher again and asked, "Teacher, tell me, can I point out the mistake to the professor?" The teacher smiled and said

With the encouragement of the teacher, Hua Luogeng quickly wrote an article and sent it to the magazine.

After some time, the postman brought him a small packet. He excitedly opened it and saw that it was a new magazine, along with a letter of praise addressed to him. "Ah, there's an article I wrote in this magazine! Hua Luogeng didn't mention how happy he was in his heart.

Since then, Hua Luogeng has studied harder and finally become a world-famous mathematician.

Copernicus Nicholas was a great Polish astronomer. With amazing genius and courage, he uncovered the secrets of the universe and laid the foundations of modern astronomy. Copernicus devoted his life to astronomical research and founded the "Theory of the Movement of Celestial Bodies", the "Declaration of Independence of Natural Science".

These achievements made him one of the greatest revolutionaries in the history of the development of human science.

One. The Life of Copernicus.

Copernicus was born on February 19, 1473, into a merchant family in the city of Toruń-sur-Vistula in western Poland. There were four brothers and sisters in the family, and Copernicus was the youngest. When he was 10 years old, his father died, and his uncle Lucas took on the responsibility of raising him.

From 1491 to 1495, Copernicus entered the University of Krakow to study. Krakow was the capital of Poland at the time, and it was also the largest ** and cultural center in Eastern Europe, where many international students studied. Because it is located at the heart of the Eastern and Western European traffic, it was influenced by the Italian Renaissance relatively early.

Thus in this old university there was a fierce struggle between the ideas of the emerging bourgeois humanism and the scholasticism of the decaying feudal church. Influenced by advanced humanist ideas, Copernicus planted in his heart the seeds of a challenge to scholasticism. Here he met Professor Brudzewski, a mathematician and astronomer who had a profound influence on his life.

It was the professor's initiation that prompted Copernicus to decide to dedicate his life to astronomical science.

In 1496 Copernicus went to Italy to study, where he studied law, astronomy, mathematics, theology and medicine at the Universities of Bologna, Padua and Ferrara, where he also learned Greek. In 1503, Copernicus received a doctorate in canon law.

1. Joule Curiosity:

Joule, a famous British scientist, has been fond of physics since he was a child, and he often does some experiments on electricity and heat by himself. Through continuous study and careful observation of calculations, he finally discovered the laws of thermal work equivalent and conservation of energy, and became an excellent scientist.

2. Prague, a British physicist, was very poor when he was a child, but with his unremitting pursuit of his dreams and tenacious efforts, he finally achieved great achievements. And the poor years he experienced became the motivation to move forward in the future.

3. In the 12 years from 1961 to 1972, the Americans successively invested 25.4 billion US dollars (1973**, equivalent to more than 200 billion US dollars today) to the 17 missions of the Apollo program, but after a series of unmanned and manned missions, the United States has carried out a total of 7 manned lunar landings since the 11th, of which 6 were successful, and 12 earthlings were successfully landed on the moon.

4, Lü Meng was the general of Wu during the Three Kingdoms, he had made great contributions many times, but he didn't like to read. So Sun Quan said to Lu Meng: "You are now a general, and you have a heavy burden on your shoulders, so you must read more and learn more."

Lu Meng began to read. Slowly, he discovers that there are a lot of things in the book that he didn't know before.

Once, he read the story of Oak Rotten to Sun Bin using the "Stove Reduction Meter" to lure Pang Juan to underestimate the enemy, and finally defeated Pang Juan, and felt that his eyes were opened. As a result, Lu Meng gradually fell in love with reading. In addition to his busy military schedule, he plunged into the stacks of books and hungrily read ancient art of war and history books.

Over the past few years, Lü Meng's military talent has greatly improved. Sun Quan was very happy, so he made Lü Meng the governor of the capital, commanding the soldiers and horses of the whole country.

5. Zhang Heng of the Eastern Han Dynasty was not only a scientist, but also a writer and painter. His achievements lie in his thoughtfulness. His famous literary works, "Xijing Fu" and "Tokyo Fu", were published after ten years of careful consideration and repeated revisions.

He invented the world's first water-powered armillary sphere.

This is a copper instrument for astronomical surveyors, which is engraved with the sun, moon and stars, which can be seen clearly in the armillary sphere when the stars rise in the east and what stars set in the west. He managed to use water power to turn this instrument, which was inspired by the "water drain" in his hometown. When he was a teenager, he visited the ironworks by the White River outside Wancheng, the land of iron.

The verdict is like a verdict. Rows of iron-making furnaces are blazing, and each furnace has a few bellows blowing air, and he has been thinking: why don't people pull the bellows? Later, he found that there was a water wheel in the White River, and the iron shaft of the water wheel was connected to gears and iron rods. This kind of "water drain" that drives the gears and bellows with water power left a deep impression and thinking on Zhang Heng, which made him later invent the "armillary sphere".
