Chen Jingrun later won the "Pearl in the Crown of Mathematics". What does this mean?
The jewel in the crown refers to the proof of Goldbach's conjecture: that is, any natural number not less than 6 can be expressed as the sum of two prime numbers.

Chen Jingrun proved that any natural number not less than 6 can be expressed in the form of p 1+p2*p3.

Where P 1, P2 and P3 are all prime numbers.

Although it is only one step away, the distance is like a gap, which human beings can't solve so far. Chen Jingrun is the closest person to Goldbach's conjecture: Bailongtong | II | 201-3-2918: 21.

Goldbach's Conjecture

From 1729 to 1764, Goldbach kept correspondence with Euler for 35 years.

In the letter 1742 to Euler on June 7th, Goldbach put forward a proposition. He wrote:

"My question is this:

Take any odd number, such as 77, which can be written as the sum of three prime numbers:

77=53+ 17+7;

Take an odd number, such as 46 1,

46 1=449+7+5,

It is also the sum of these three prime numbers. 46 1 can also be written as 257+ 199+5, which is still the sum of three prime numbers. In this way, I found that any odd number greater than 7 is the sum of three prime numbers.

But how can this be proved? Although the above results are obtained in every experiment, it is impossible to test all odd numbers. What is needed is a general proof, not another test. "

Euler wrote back: "This proposition seems correct, but he can't give a strict proof. At the same time, Euler put forward another proposition: any even number greater than 2 is the sum of two prime numbers, but he failed to prove this proposition. "

It is not difficult to see that Goldbach's proposition is the inference of Euler's proposition. In fact, any odd number greater than 5 can be written in the following form:

2N+ 1=3+2(N- 1), where 2(N- 1)≥4.

If Euler's proposition holds, even number 2(N- 1) can be written as the sum of two prime numbers, and odd number 2N+ 1 can be written as the sum of three prime numbers, so Goldbach conjecture holds for odd numbers greater than 5.

But the establishment of Goldbach proposition does not guarantee the establishment of Euler proposition. So Euler's proposition is more demanding than Goldbach's proposition.

Now these two propositions are collectively called Goldbach conjecture.

=================================================

Chen Jingrun (1933.5~ 1996.3) is a modern mathematician in China. 1933 was born in Fuzhou, Fujian on May 22nd. 1953 graduated from the Mathematics Department of Xiamen University. Because of his improvement in problems, Hua attached great importance to it. He was transferred to the Institute of Mathematics of China Academy of Sciences, first as an intern researcher and assistant researcher, and then promoted to a researcher by leaps and bounds, and was elected as a member of the Department of Mathematical Physics of China Academy of Sciences.

Chen Jingrun is one of the world famous analytic number theorists. In the 1950s, he made important improvements on the existing results of Gauss circle lattice point problem, sphere lattice point problem, Tali problem and Waring problem. After 1960s, he made extensive and in-depth research on screening methods and related important issues.

1966, Chen Jingrun, who lives in a 6-square-meter hut, borrowed a dim kerosene lamp, leaned against the bed board and used a pen to consume several sacks of draft paper. He actually conquered (1+2) in the world-famous mathematical puzzle "Goldbach conjecture", creating a distance from taking off the crown jewel of number theory (1+66). He proved that "every big even number is the sum of the products of a prime number and no more than two prime numbers", which made him a world leader in Goldbach's conjecture research. This result is called "Chen Theorem" internationally and is widely quoted. This work also enabled him, Wang Yuan and Pan Chengdong to win the first prize of China Natural Science Award with 1978 * *. His achievements in studying Goldbach conjecture and other number theory problems are still far ahead in the world. A world-class master of mathematics and American scholar A Will (A? Weil) once praised him like this: "Every job in Chen Jingrun is like walking on the top of the Himalayas."

1978 and 1982, Chen Jingrun gave a 45-minute lecture at the invitation of the International Congress of Mathematicians. This is the pride and pride of China people. His achievements and honors have set up an immortal banner for thousands of intellectuals in Qian Qian, Qian Qian, reflecting the three mountains and five mountains and calling on hundreds of millions of young people to forge ahead.

Chen Jingrun has published more than 70 academic papers.

Goldbach's Conjecture

From 1729 to 1764, Goldbach kept correspondence with Euler for 35 years.

In the letter 1742 to Euler on June 7th, Goldbach put forward a proposition. He wrote:

"My question is this:

Take any odd number, such as 77, which can be written as the sum of three prime numbers:

77=53+ 17+7;

Take an odd number, such as 46 1,

46 1=449+7+5,

It is also the sum of these three prime numbers. 46 1 can also be written as 257+ 199+5, which is still the sum of three prime numbers. In this way, I found that any odd number greater than 7 is the sum of three prime numbers.

But how can this be proved? Although the above results are obtained in every experiment, it is impossible to test all odd numbers. What is needed is a general proof, not another test. "

Euler wrote back: "This proposition seems correct, but he can't give a strict proof. At the same time, Euler put forward another proposition: any even number greater than 2 is the sum of two prime numbers, but he failed to prove this proposition. "

It is not difficult to see that Goldbach's proposition is the inference of Euler's proposition. In fact, any odd number greater than 5 can be written in the following form:

2N+ 1=3+2(N- 1), where 2(N- 1)≥4.

If Euler's proposition holds, even number 2(N- 1) can be written as the sum of two prime numbers, and odd number 2N+ 1 can be written as the sum of three prime numbers, so Goldbach conjecture holds for odd numbers greater than 5.

But the establishment of Goldbach proposition does not guarantee the establishment of Euler proposition. So Euler's proposition is more demanding than Goldbach's proposition.

German mathematician Goldbach put forward that' any even number can represent the sum of two prime numbers', abbreviated as 1+ 1. He has never proved it in his life. Later, Goldbach passed away with a lifetime of regret, but left this math problem behind. Goldbach conjecture is an interesting metaphor. Mathematics is the queen of natural science, "Goldbach conjecture" has become a big unsolved mystery in mathematics, mathematics is the queen of natural science, "Goldbach conjecture is the jewel in the queen's crown! Chen Jingrun proved Goldbach's conjecture with repeated mathematical calculations, and changed the original "1+ 1" into "2+ 1", so Chen Jingrun later won the "jewel in the crown of mathematics". Interviewee: The pain is particularly severe | Level 1 | 201-3-3021:29.

Goldbach conjectures that this world-class mathematical problem that has been unresolved for more than 200 years has attracted the attention of thousands of mathematicians all over the world, but few people can really challenge this problem. In high school, Chen Jingrun listened to his teacher's philosophical remarks: the queen of natural science is mathematics, the crown of mathematics is number theory, and Goldbach conjecture is the jewel in the crown. This crucial enlightenment became his unswerving goal all his life.

In order to prove Goldbach's conjecture, Chen Jingrun studied mathematics day and night and found this world-famous pearl of mathematics. Chen Jingrun trudged in the field of mathematics with amazing perseverance. Hard sweat has brought fruitful results. 1973, Chen Jingrun finally found a simple method to prove Goldbach's conjecture. After his achievement was published, it immediately caused a sensation in the world. Among them, "1+2" was named "Chen Theorem", also known as the "glorious vertex" of the screening method. Hua and other mathematicians of the older generation spoke highly of Chen Jingrun's paper. Mathematicians from all over the world have also published articles praising Chen Jingrun's research achievement as "the best achievement in studying Goldbach's conjecture in the world at present".

About 200 years ago, a German mathematician named Goldbach proposed that' any even number can represent the sum of two prime numbers', abbreviated as 1+ 1. He never proved it in his life, so he wrote to Euler, a mathematician in St. Petersburg, Russia, and asked him to help prove the problem. After receiving the letter, Euler began to calculate. He tried to prove it to the death. Later, Goldbach passed away with a lifetime of regret, but left this mathematical problem behind. For more than 200 years, Goldbach's conjecture has attracted many mathematicians, thus becoming a big unsolved mystery in the field of mathematics. "For an interesting example, mathematics is the queen of natural science, and Goldbach conjecture is the jewel in the queen's crown! Interviewee: 1 144653489 | Level II | 2011-4-817: 06.
