Twin prime numbers refer to prime number pairs with a difference of 2, such as 3 and 5, 5 and 7, 1 1 and 13. This conjecture was formally put forward by Hilbert in the eighth topic of the report of the International Congress of Mathematicians in 1900. It can be described as follows: there are infinitely many prime numbers P, so that p+2 is a prime number.

In 1849, Alfonso de Polignac put forward a general conjecture: for all natural numbers k, there are infinite prime pairs p,? The case of p+2k .k= 1 is the twin prime conjecture.

In May of 20 13, Zhang made a breakthrough in the study of twin prime numbers, and proved a weakened form of the conjecture of twin prime numbers. In the latest research, Zhang did not rely on unconfirmed inference, and found that there are infinitely many prime pairs with a difference of less than 70 million, thus taking a big step forward on the road of the important problem of twin prime conjecture.

Zhang's paper was published online on May 4th/KLOC-0, and officially published on May 2nd1day. On May 28th, this constant dropped to 60 million. Only two days later, on May 3 1, it dropped to 42 million. Three days later, June 2nd,130,000. The next day, 5 million. On June 5, 400 thousand.

The importance of learn mathematics:

1. Mathematics is closely related to our life. To say that the real effect of learning mathematics is not reflected in exam-oriented education, but in my own thinking about the future.

2. The importance of mathematics is self-evident. Mathematics is the foundation of all sciences and an important channel to cultivate logical thinking. It can be said that every major progress of our mankind is strongly supported by mathematics.

3. The application of mathematical knowledge in life is everywhere. From the calculation of daily living costs, to astronomy, geography, quality control, agricultural economy, aerospace, there are shadows of using mathematics.
