What is mathematics? Mathematicians R. Coe and H. Robin wrote a book about popular mathematics to tell you. Whether you are a math major or want to learn math, you can read this book. Especially for high school students, college students and middle school math teachers, it is an excellent reference book. This book profoundly and vividly expounds the basic concepts and methods in the whole field of mathematics. The New York Times commented that this book is a perfect book for beginners, experts, students and teachers, philosophers and engineers.

This reminds me that when I was in junior high school, I was not interested in mathematics. I thought mathematics was too simple, and I could understand it as soon as I learned it. It can be measured that a later math class influenced my life.

That was when Sue was in the third grade. When he was in XX middle school, a teacher Yang who had just returned from studying in Tokyo taught mathematics. In the first class, Mr. Yang didn't talk about math, but told stories. He said: "A long time ago, the law of the jungle prevailed in the world. The world powers profited from their ships and guns, and all wanted to occupy and carve up China. The danger of China's national subjugation and extinction is imminent, so we must revitalize science, develop industry and save the nation. Every student here has a responsibility to' rise and fall in the world'. " He quoted and described the great role of mathematics in the development of modern science and technology. The last sentence of this class is: "In order to save the country and survive, we must revitalize science. Mathematics is the pioneer of science. In order to develop science, we must learn math well. "I don't know how many classes Sue took in her life, but I will never forget this lesson.

Teacher Yang's class deeply touched me, and he injected new stimulants into my mind. Reading is not only to get rid of personal difficulties, but to strengthen the country; Reading is not only to find a way for individuals, but to create for the Chinese nation. That night, I tossed and turned and couldn't sleep all night. Under the influence of Teacher Yang, Su's interest shifted from literature to mathematics, and since then, she has set the motto "Never forget to save the country when reading, and never forget to save the country when reading". I am fascinated by mathematics. No matter in hot winter, frosty morning or snowy night, I only know reading, thinking, solving problems and calculating. I have worked out tens of thousands of math exercises in four years. When I graduated from middle school, my scores in all subjects were above 90.

/kloc-At the age of 0/7, Su went to Japan to study, and won the first place in Tokyo Technical School, where she studied eagerly. The belief of winning glory for our country drove Su to enter the field of mathematics research earlier. At the same time, he has written more than 30 papers, and made great achievements in differential geometry, and obtained the doctor of science degree in 193 1. Before receiving her doctorate, Su was a lecturer in the Department of Mathematics of Imperial University of Japan. Just as a Japanese university was preparing to hire him as an associate professor with a high salary, Su decided to return to China to teach with his ancestors. After the professor of Zhejiang University returned to Suzhou, his life was very hard. In the face of difficulties, Su's answer is, "Suffering is nothing, I am willing, because I have chosen the right road, which is a patriotic and bright road!" "

I read it, and I have skills in math. As long as you master the skills, you will succeed.
