1930 One day, Xiong Qinglai, head of the Department of Mathematics at Tsinghua University, was sitting in his office reading a magazine Science. Looking at it, I can't help but exclaim: "Which country is this China from?" "Which university does he teach at?" Finally, a teacher from Jiangsu said slowly, "My brother has a classmate named Hua who only went to junior high school. Xiong Qinglai was surprised and invited Hua to Tsinghua University.

Since then, Hua has become a teaching assistant in the Department of Mathematics of Tsinghua University. The following year, his papers began to be published in famous foreign mathematical magazines. A few years later, Hua was sent to Cambridge University in England to study. His theory was named "Fahrenheit Theorem" by the mathematical community.

Mathematics in life

Learning mathematics should be used in real life. Mathematics is used by people to solve practical problems. In fact, there will be math problems in life. For example, when you go shopping, you will naturally use addition and subtraction, and you always have to draw pictures when you build a house. There are countless problems like this, and this knowledge comes from life and is finally summed up as mathematical knowledge, which solves more practical problems.

I once saw a report that a professor asked a group of foreign students, "How many times will the minute hand and the hour hand overlap between 12 and 1?" Those students all took off their watches from their wrists and began to set hands; When the professor tells the same question to the students in China, the students will use mathematical formulas to make calculations. The commentary said that it can be seen that China students' mathematical knowledge is transferred from books to their brains, so they can't use it flexibly. They seldom think of learning and mastering mathematics knowledge in real life.

From then on, I began to consciously connect mathematics with daily life. once
