1. Zhan Tianyou is a national disregard for fame and profit: Zhan Tianyou, a pioneer of modern science and a famous engineer, was full of patriotic enthusiasm and was ordered to build the Beijing-Zhangjiakou Railway in the face of the difficult situation of having no capital, no technology and no talent in China. With the spirit of selflessness and hardship, he traveled all over the mountains and mountains between Beijing and Zhangjiakou, and it took only 5 million yuan and 4 years to build the Beijing-Zhangjiakou Railway, which was planned for foreigners to cost 9 million yuan and took 7 years to complete.

The foreign experts who came to visit were all shocked and amazed. At that time, in recognition of Zhan Tianyou's achievements, some universities in the United States decided to award him a doctorate in engineering and invited him to attend the ceremony. However, Zhan Tianyou was tasked with the design of another railway, so he resolutely declined the invitation.

His spirit of serving the country and not making personal merits has won praise at home and abroad.

2. Hua Luogeng resolutely returned to China: Hua Luogeng, a great mathematician, returned to the motherland from the United Kingdom, where the anti-Japanese beacon was burning everywhere, after the "July 7" incident, not for money and degrees, and actively participated in the anti-Japanese salvation movement after returning to China. In 1950, he had become an internationally renowned first-rate mathematician and was hired as a tenured professor at the University of Illinois in the United States, but he resolutely led his family back to the newly liberated motherland.

3. Zheng Chenggong's recovery of Taiwan: As early as 1624, Dutch colonialism sent troops to invade Taiwan, China's territory, and implemented extremely barbaric and cruel rule, and the Taiwanese people fought heroically against the invaders. In 1661, Zheng Chenggong, who led the anti-Qing struggle on the southeast coast, led more than 350 warships and more than 25,000 soldiers to encircle Taiwan.

Taiwan has returned to the embrace of the motherland.

4. Patriotic hero Yang Jingyu: Yang Jingyu participated in the revolution at the age of 21, in the early 1940s, he was besieged by the Japanese army, was seriously wounded, and could not gnaw the bark, so he could only swallow the cotton in the cotton clothes and the ice and snow to satisfy his hunger. When the Japanese army failed to persuade them to surrender, they let go of their guns, and Yang Jingyu, who was only 35 years old, died heroically.

The brutal Japanese soldiers dissected his body, and when they saw that there were only weeds and cotton wool in his stomach, these invaders who were overwhelmed by the anti-Japanese coalition led by Yang Jingyu were all stunned. In the dense forests of Changbai Mountain, the force that supports Yang Jingyu's fight against the enemy is a love for the motherland.

5. Hua Luogeng returned to China: In 1950, mathematician Hua Luogeng gave up his tenured professorship in the United States and went to the motherland. On the way back, he wrote an open letter to students studying in the United States, in which he said:

In order to choose the truth, we should go back; For the sake of the country and the nation, we should go back; In order to serve the people, we should go back; Even for the sake of a personal outlet, we should go back as soon as possible, establish the foundation of our work, and strive for the construction and development of our great motherland. After returning to China, Hua Luogeng conducted research on applied mathematics, covering 23 provinces, municipalities and autonomous regions across the country, using mathematics to solve practical problems in a large number of production, and was known as the "people's mathematician".

Galileo was curious and inquisitive: Galileo was a great Italian physicist and astronomer, and his contribution to mechanics was to establish the law of falling bodies, discover the law of inertia of objects, the isochronism of pendulum vibration, the law of parabolic motion, and determine Galileo's principle. During his time at the University of Pisa, he was very curious and often asked questions such as, "Why don't the planets go in a straight line?"

Some teachers think he has too many questions, but he never cares, and he should ask and ask. Once, when Galileo learned that the mathematician Leach had traveled to Pisa, he prepared many questions for Leach. This time it was good, the teacher was tireless, and the students asked endlessly.

Galileo soon learned about plane geometry, solid geometry, etc., and mastered Archimedes' theories about levers, the specific gravity of floating bodies, etc.
