Second-grade mathematics handwritten newspaper materials: the story of Zhu Shijie, a mathematician in Yuan Dynasty
/kloc-At the end of 0/3, the war-torn motherland was unified by the Yuan Dynasty, and the destroyed economy and culture flourished rapidly. For the sake of national prosperity and security, Mongolian rulers respect knowledge, select talents and push all sciences to a new height. One day, by the scenic Slender West Lake in Yangzhou, a teacher came and hung a sign in front of his apartment, which read in big letters: "Teacher Zhu Songting of Yanshan specializes in teaching four elements." A few days later, Zhu Shijie's front door was crowded with people who were curious about knowledge. Just as Zhu Shijie was accepting students' registration, suddenly, a lot of yelling caught his attention. I saw a semi-old Xu Niang dressed in silk and silver chasing a young girl, beating and cursing: "You woman, you didn't catch a lot of money. Do you want to be a good family? I am afraid that you will vote for the wrong baby and will not think about it in the next life. " The girl was beaten so badly that even the clothes inside her were torn. The girl curled up into a ball and asked her to fight, but she didn't go back with her. When Zhu Shijie saw that the road was rough, he came forward to ask. Xu Niang, a half-aged man, saw a nosy person and sneered, "Do you want to be keen? You give me fifty taels of silver, and the girl is yours! " Zhu Shijie was furious at this. "Can't I pay fifty taels of silver?" . You can't run amok in broad daylight. Is there no king's law? "Old Xu Niang said sarcastically," you poor wretch, what are you talking about? Silver is the king. I won't fight if you can pay fifty taels of silver. "
Zhu Shijie was so angry that he took out 50 taels of silver from his pocket, threw it in front of Xu Niang, picked up the girl and went back to his teaching place. It turned out that Xu Niang, who was half-aged, was the madam of a prostitute's family. The girl's father borrowed 10 silver from the madam, but he could not pay back the money due to natural disasters, so he had to sell his daughter to pay off his debts. I happened to meet Zhu Shijie today and let this girl out of her misery. Later, under the careful instruction of Zhu Shijie, the girl also learned a lot of mathematics and became Zhu Shijie's right-hand man. In a few years, the two became husband and wife. Therefore, there is a saying among Yangzhou people: Zhu Hanqing taught and educated people in Yuan Dynasty. Saving people from fire and water, a big marriage.
Second-grade mathematics handwritten newspaper materials: the short story of mathematician Jacob Bernoulli
Jacques Bernoulli, a Swiss mathematician, studied the spiral (known as the thread of life) before his death. After his death, a logarithmic spiral was carved on the tombstone, and the inscription also read: "Although I have changed, I am the same as before." This is a pun, which not only describes the essence of spiral, but also symbolizes his love for mathematics.
