Chapter 68
At this moment, there was a voice from the door
"Dad, you are back."Chen Keke couldn't help laughing when he saw his father.
Who would have thought that such a scientist and mathematician who is so popular all over the world would look like this at home.
Lying casually on the sofa, next to him There are boring soap operas on TV
"Well, Coco. How was this journey?"Chen Fan opened his eyes
"Pretty good."Chen Keke said,"There are just too many social events."
"Then there is no need to socialize."Chen Fan said lightly. The domineering tone in his tone was undoubtedly evident.
With Chen Keke, it can be said that there are business elites from various countries, and even confidential politicians.
"Still need it occasionally."Chen Keke stuck out her tongue. She is not her father.
Although everyone who socializes with her now is doing it for her father's sake, she still has to work hard. At least to balance her father and those elite bosses. relationship.
At least it will be easier to do things in the future.
Chen Fan accepted the second task given by the system.
"logic code."
To complete the character, we must study the carrier theory.
It sounds very simple, but in fact, it contains a wide range of things.
Research.
Eat.
Research.
Eat, then rest.
His laboratory has always been independent, so independent that only He can decide who can enter his laboratory, even if it is the principal or even a higher-level leader who comes to inspect.
He takes off his white coat and ends the day's research.
"Dean."
As soon as Chen Fan walked out of the laboratory, Professor Sun Yuan, who had been waiting outside, came up.
He is engaged in mathematics research and is also a famous domestic mathematician. He often comes to Chen Fan to ask questions.
"See if you can figure out my guess."Professor Sun Yuan said with some pride.
"If you have any conjectures, tell me."Chen Fan said.
Regarding mathematical conjectures, he has always held the idea that there are good things to do. Especially when a good conjecture is put forward, it will attract many people to study one after another.
Of course, in the eyes of ordinary people, this Perhaps it is a complete waste of time.
But in fact, it is not.
Mathematical conjecture can be briefly explained from three aspects.
The first aspect is that it is a powerful driving force for the development of mathematical theory. Mathematical conjecture is one of the most active, active and positive factors in the development of mathematics, and it is the most creative part of human rationality.
Good and difficult conjectures can strongly attract mathematicians to devote themselves wholeheartedly and actively carry out relevant research. It strongly promotes the development of mathematics.
And once mathematical conjectures are proven, they will be transformed into theorems and integrated into mathematical theories, thus enriching mathematical theories.
For example, the four-color conjecture, one of the three major mathematical conjectures in the world, has been proven. It became the four-color theorem and was added to mathematics books.
Secondly, it is also an important way to create mathematical thinking methods. The history of mathematical development shows that mathematicians create in the process of trying to solve mathematical conjectures (whether they are finally solved or not). A large number of effective mathematical thinking methods have been developed, and these mathematical methods have penetrated into various branches of mathematics and play an important role in mathematical research.
The third aspect is to explore the rules of the emergence and development of mathematical conjecture as a research model. An important foundation for mathematical research methods
; secondly, as a research method, mathematical conjecture itself is the research object of mathematical methodology. By studying the regularity of some new methods shown in solving mathematical conjectures, it promotes the research of general principles of mathematical methodology. ;
Finally, mathematical conjecture is an important form of the development of mathematics, and it is a concrete manifestation of scientific assumptions in mathematics.
Therefore, it is not a boring and useless thing in the eyes of some people.
"My guess is this."When Professor Sun Yuan said this, his body trembled slightly with excitement. As a mathematician, he proposed conjectures and asked others to study and prove them.
This is undoubtedly an affirmation of this mathematician and can be remembered throughout the ages. kind of
"For a positive integer x, if it is an odd number, multiply it by 3 and add 1. If it is an even number, precipitate the even factor 2. In this way, after several times, it will finally return to 1."Professor Sun Yuan said excitedly.
Huh?
Chen Fan paused in his walking steps for a moment. He quickly made some calculations in his mind, which was a bit interesting.
He took out the pen in his pocket and started to calculate directly on the white wall.
This guess The biggest charm lies in unpredictability.
Write a positive integer N arbitrarily and transform it according to the following rules: if it is an odd number, the next step becomes
3N+1. If it is an even number, the next step becomes N/. 2.
So no matter what number N is, you can't escape back to the bottom of 1. To be precise, you can't escape the 4-2-1 cycle of falling to the bottom, and you can never escape this white wall. There was already a piece of writing on it.
Many people gathered around and watched Chen Fan's calculations quietly.
They already knew Professor Sun Yuan's guess and had calculated it, but they had no answer.
