The story of Hua's return to the motherland 1946 The famous mathematician Hua was invited to give lectures in the United States, which was highly valued by the academic community. At that time, the University of Illinois signed a life-long contract with him with an annual salary of 1 10,000 dollars. Life in China suddenly became comfortable. Not only does he have a small building, but the university has specially equipped him with four assistants and a typist. After the founding of New China, some people always thought that Hua had become famous in the United States and lived a comfortable life, so he would never come back.

However, material, money and status did not bind his patriotism. 1950 In February, Hua resolutely gave up the treatment of Professor Guo in the United States and broke through the heavy blockade and returned to the motherland. When passing through Hong Kong, he wrote an open letter to students studying in the United States, expressing his enthusiasm for devoting himself to his motherland. He warmly appealed: "For the sake of the country and the nation, we should go back!" "Although Chengdu is happy, it is better to go back to your hometown; Although Liangyuan is good, it is not a place to stay for a long time. "

The understanding of zero seems monotonous, but it is not. Actually, it's very rich, and it hides a lot. Zero is very special in mathematics. No matter what you do, you should consider zero. "0" is often used as a symbol in geometry. The uniqueness of "0" stems from some concepts or problems. For example, every rational number has a reciprocal, but "0" does not. Rational numbers are divided into positive numbers and negative numbers. "0", a number is divided into one category, isn't this special? In divisor, only zero cannot be divided. Zero is the dividend. No matter what number you divide (except "0"), you will get zero.

The above are the written materials related to mathematics that I have compiled. Thank you for reading.
