Zhan Tianyou, born on April 26th, 186 1, died on April 24th,19/9. Born in Wuyuan, Anhui Province, he was the first railway engineer in China. He was responsible for the construction of the "Beijing-Zhangjiakou Railway" and other projects, and was known as "the father of Chinese railways". Zhan Tianyou was born in 186 1 (the 11th year of Xianfeng in Qing Dynasty) to an ordinary family of tea merchants. Zhan Tianyou, a teenager, is very interested in machines, and often makes various machine models with the children in the neighborhood. Sometimes, he would secretly open the bell at home, fiddle with it, ponder over the components inside and ask questions that even adults could not answer. The villagers envied the child. From 65438 to 0872, Zhan Tianyou, who was only 12 years old, went to Hongkong to sign up for the preparatory class for young children going abroad organized by the Qing government. After passing the exam, my father drew a note on a certificate of going abroad, which said, "If there is illness, life and death, everyone will live in peace." After that, he left his parents and came to the United States to study with the ideal of learning western "skills". In the United States, students of overseas preparatory classes witnessed the great achievements of science and technology in North America and Western Europe and marveled at the rapid development of machinery, trains, ships and telecommunications manufacturing. Some students are pessimistic about the future of China, but Zhan Tianyou firmly said, "In the future, there will be trains and ships in China." With the belief of studying hard for the prosperity of the motherland, he studied hard and graduated from New Haven with 1877. In May of the same year, he was admitted to the Department of Civil Engineering of Yale University, majoring in railway engineering. After four years in college, Zhan Tianyou studied hard, ranking first in the graduation examination with excellent results.

Qian Xuesen loved Chinese painting since childhood. He could have been a painter, but he knew that the motherland was in urgent need of scientific and technological talents. Therefore, he had to reluctantly give up what he loved and study engineering instead of painting. Now that he has returned to his hometown for illness, he has time. Besides, the scenery in his hometown is so beautiful that it really itches. Seeing through his son's mind, his father invited a local painter to be his teacher and guide him to learn Chinese painting. As a result, Qian Xuesen got several months of painting exercise.

Qian Xuesen painted, mainly sketching. The teacher accompanied him to the West Lake, helped him choose the scenery, and taught him how to outline the outline with carbon ribbon first, and then how to color it. Soon, Qian Xuesen mastered the basic techniques of landscape painting, and his painting level was greatly improved. One day, he took out a few sketches for his parents to see, and was praised as expected. He is also very happy. He told his parents: "When I observed the scenery and painted with a pen, the scenery melted into my heart. At that time, I forgot everything and my heart was very clean. "

However, this leisurely life is always limited. Soon, I will go back to Shanghai to study. Every time I think about it, there is always a deep sense of attachment around his heart. He really doesn't want to leave his hometown and parents. One day, he said to his mother, "My hometown is beautiful, and the West Lake is beautiful. Being with my parents and the West Lake is the happiest day of my life. "

Mother smiled and said, "It's a pity that fate predestined that you can't stay in your hometown forever, stay with your parents forever, and stay with the West Lake forever. A good man is ambitious and has the courage to go global. "

Qian Xuesen's parents are so reasonable and open-minded, which is the greatest luck in his life. Later, he borrowed a sentence from Freud to express his special feelings: "People who are infinitely loved by their parents will keep the feelings of conquerors all their lives, that is, they will always succeed in reality."

Qian Xuesen, like other children of the same age, is lively and active, loves learning and playing all kinds of games. In his spare time, he often plays darts with his friends.

Darts are made of hard waste paper, with sharp heads and a pair of wings swept back, flying like swallows. Everyone can fly darts, but not everyone can fly well. Some just throw it out and stick it on the ground, others don't fly forward, but fly back in circles Only the flying saucer shaken by Qian Xuesen flies farthest, like a sharp arrow straight into the target.

"What is this?" Some college students are not convinced, competing again and again and failing again. They shouted that Qian Xuesen's darts were haunted. Therefore, Qian Xuesen's darts were picked up and opened until they became a piece of paper. Although there are no "ghosts" in it, they still insist that Qian Xuesen's darts have "ghosts". This matter has been discovered by their science teacher. The teacher came to restore Qian Xuesen's darts and let Qian Xuesen throw them again. Darts do fly far and steadily. Then, the teacher smiled and gathered the students around him, holding Qian Xuesen's darts and saying, "As you can see, darts don't have ghosts, but there are secrets here. Now let Qian Xuesen tell you the secret of his darts flying far and steadily! "

When some big classmates shouted that Qian Xuesen's darts were ghosts, Qian Xuesen didn't rush to refute them, just thought they were angry and ridiculous. Now the teacher asked him to tell the secret of his darts, but he blushed shyly.

Qian Xuesen said in a low voice, "My darts have no secrets. I have failed many times, and slowly changed little by little. The paper I use to make darts is very smooth. The head of the dart should not be too heavy. If it is heavy, it will stick. Not too light. If the head is light, the tail is heavy. Fly first and then fall. If the wings are too small, it will not fly smoothly; Too big to fly far, like beating around the bush. That's it. "

"Well said." The nature teacher shouted happily, "Little dart, there is science in it. After thinking hard, Qian Xuesen explored two ways to stack darts from failure, one is to keep balance, the other is to reduce resistance, and he can skillfully use wind and buoyancy to make darts fly far and steadily. Everyone said right? "

"Yes!" The students answered in unison.

The nature teacher looked at Qian Xuesen who was far away and couldn't help but marvel: this little classmate is really smart. He seems to understand some common sense of aerodynamics. I may become a very successful scientist in the future ... "

Qian Xuesen has just turned five and can read Water Margin. And I am particularly interested in the characters in the Water Margin. What 36 highest sun stars and 72 earth stars are all heroes in his mind. One day, he suddenly said to his father:

"The 108 heroes in Water Margin turned out to be 108 stars from the sky. Are all the great men who do great things in the world stars in the sky? "

The father was stunned by his son's question and didn't know how to answer his son's question at the moment. After a pause, Qian Junfu smiled and said to his son, "The Water Margin is a story written by people. In fact, all heroes and great men, such as Yue Fei, Zhuge Liang and now Sun Yat-sen, are not stars in the sky. They are all ordinary people. It's just that they love learning since childhood, have great ambitions, determination and perseverance, and are not afraid of difficulties, so they have made earth-shattering things. "

Qian Xuesen blinked and said seriously, "If heroes are not bought by the stars in the sky, then I can be a hero."

Father said happily, "You can be a hero, too. However, we must study hard, study hard and make contributions to society. "

In the later days, Qian Junfu told his son many times the truth of "learning knowledge and contributing to society". These eight words became Qian Junfu's family motto, deeply imprinted in Qian Xuesen's young mind.
