Volume 1: Student Life Chapter 176 I Choose You
After coming out of the classroom, Chen Zhou went straight to the library.
Yang Yiyi was still waiting for him in the library.
The algebra discussion class starts at 6:30 in the evening, and it is only 9 o'clock now, so there is still some time before the library closes.
Chen Zhou happened to go to the library to sort out his thoughts.
It has to be said that the library of Yanda University was still crowded at this time.
Chen Zhou followed his usual route, moving nimbly between the study areas.
Soon, he saw Yang Yiyi who was reading a book with her head down.
There was an empty seat next to Yang Yiyi, with some books on it.
One of the books was open, with a pen tucked inside.
When he walked to Yang Yiyi, Chen Zhou did not disturb him, but instead stretched his head to take a look.
Yang Yiyi was reading the relevant literature on her mechanics topic.
What Chen Zhou found very strange was that he had never seen Yang Yiyi process the experimental data.
Generally speaking, the research methods of mechanics follow the basic laws of epistemology, that is, from practice to theory and then back to practice.
Unlike pure mathematics research, physics research is usually based on experiments.
Through the observation of experimental phenomena and the results of quantitative observation, the qualitative relationship between quantities is extracted.
Or, design scientific experiments for a specific theory, and verify and improve the theory based on the analysis of the experimental results.
Of course, there are also ways to study physical theories without using ordinary experiments.
That's theoretical physics.
The commonly used experimental method in theoretical physics is the ideal experiment. In layman's terms, it is to conduct experiments in the mind, also known as a thought experiment.
The outstanding master in this field is Einstein.
Maybe Yang Yiyi and his colleagues’ research topic also falls within the scope of theoretical physics?
Thinking this way, Chen Zhou did not intend to ask more questions. He believed in Yang Yiyi's ability and judgment.
Just as Yang Yiyi would not interfere with his research, he would not take the initiative to interfere with Yang Yiyi's research before Yang Yiyi asked for his opinion.
After taking another look at Yang Yiyi who was concentrating on studying the literature, Chen Zhou gently pulled out the chair beside him and sat down.
Just as Chen Zhou was preparing the books on the table, he heard Yang Yiyi's voice: "Sorry, someone is sitting here. He went to the toilet."
Chen Zhou's hands paused, he glanced at Yang Yiyi, then glanced at the books on the table, and instantly understood.
It turned out that these books were placed there intentionally by Yang Yiyi in order to reserve space.
Seeing that the person next to her didn't move, Yang Yiyi tilted her head slightly. Just as she was about to say it again, she saw Chen Zhou looking at her with a smile on his face.
Yang Yiyi scolded, "Why didn't you tell me you were here? I thought you were here to grab a seat again."
Chen Zhou explained, "I saw that you were so engrossed in what you were watching that I didn't disturb you. Are there many people trying to grab seats?"
Yang Yiyi nodded slightly: "You are the seventh."
Chen Zhou smiled and asked, "So you always tell them that I went to the toilet?"
"Yeah." Yang Yiyi replied, and after a pause, she added, "If someone asks me about it, I'll say you have diarrhea and you're probably stuck in the toilet."
After saying that, Yang Yiyi looked at Chen Zhou with a smile.
Chen Zhou shook his head slightly: "I'm afraid he must have eaten ten kilograms of croton seeds..."
“Ahem!”
Hearing this voice, Chen Zhou immediately raised a finger and made a gesture of silence.
Yang Yiyi understood, turned around and continued to read her own documents.
Chen Zhou took a look at the source of the cough and couldn't help but feel a little strange. Why is it always this person?
He withdrew his gaze, took out a draft paper, and began to organize his ideas for this small class.
In fact, Zhang Zhongyuan just took a group of students to appreciate the charm of the hail conjecture, but did not provide any groundbreaking ideas.
Moreover, the last thinking question assigned by Zhang Zhongyuan was just a simple one.
However, this class aroused Chen Zhou's curiosity.
Maybe it wouldn't be a bad idea to take the hail hypothesis as a new research topic?
Chen Zhou spent ten minutes to finish the summary.
Looking at the contents written on the draft paper, Chen Zhou habitually took up a pen and tapped the draft paper.
"A simple math game?"
Chen Zhou thought about it, put the pen in his hand on the draft paper, and began to calculate.
Although formally speaking, the final calculation result of the hail conjecture is 1.
But this is just a more convenient way of saying it.
In fact, whether it was in the small class, whether it was Chen Zhou or other students trying to substitute numbers, the final calculation ended with "4→2→1".
Of course, this is just a conclusion.
If you want to work backwards, it is impossible.
Chen Zhou put down his pen and took another look at the draft paper. Suddenly, his eyes lit up.
Take out a new piece of draft paper and start calculating again.
This time, he changed the rules of the game.
Chen Zhou changed the calculation rules of the hailstone conjecture to: given an arbitrary natural number N, if it is an even number, divide it by 2; if it is an odd number, multiply it by 3 and then subtract 1.
After some calculations, Chen Zhou discovered an interesting phenomenon.
The calculation results under this rule will result in three forms of cycles.
The first one is the “1→2→1” cycle.
The second one is the cycle of “5→14→7→20→10→5”.
The third one is the cycle of “17→50→ 25→74→37→110→55→164→82→41→122→61→182→91→272→136→68→34→17”.
This means that once the numbers 1, 5, and 17 are calculated, the cycle will begin.
"Interesting..." Chen Zhou muttered to himself.
In fact, it is not just Chen Zhou. Many mathematicians have changed the rules to make the hail conjecture more interesting .
But in the end, it just came to an interesting conclusion.
It is far from enough to verify the hail hypothesis through mathematical methods.
Just as Chen Zhou was about to take his computer out of his backpack, the library was about to close.
Chen Zhou put the computer back in dismay. He had originally planned to come here to sort out his thoughts and then make a final decision on whether he really wanted to take the hail hypothesis as a research topic.
As a result, I fell into a math game.
Moreover, the more calculations are made, the more interesting it becomes...
Games are indeed addictive.
Chen Zhou sighed in his heart, but then he decided to choose you, Hail Conjecture!
However, Chen Zhou also set limits for himself.
If he has not achieved satisfactory results during the military training in Huairou by this summer.
Then he must give up decisively and choose a simpler subject again.
After all, time waits for no one.
Not to mention, he also has to complete two graduation theses in the Department of Mathematics and the Department of Physics next year.
The time limit for system tasks alone is right there.
He couldn't possibly give up the reward for the system task for nothing, right?
What if he hasn't solved the hail hypothesis by the end of the mission? Wouldn't that be a waste of time?
