After Chen Zhou completely wiped out the only thing he had to feel good about himself.

Then he concentrated on the theoretical calculation of the mass of the rubber ball using the qcd summation rule.

Chen Zhou's plan was to allocate the day to physics and the evening to mathematics, focusing on the theoretical knowledge of rubber balls.

Wait until the glue ball theory of these conventional quantum numbers and the glue ball theory of those strange quantum numbers are all sorted out.

Then adjust the plan to a rotational model.

Rotation mode, that is, half day of physics and half day of mathematics.

Evening is also considered as half a day, and they rotate in sequence.

Of course, this rotation model of learning and research is not inevitable.

If an idea is not open, always immerse yourself in it.

Then, time will automatically move backward.

The reason for this arrangement is that Chen Zhou does not want his possible, fleeting inspiration to be interrupted by a rigid plan that is not completely necessary.

At six o'clock in the afternoon, Chen Zhou put down the pen in his hand and stretched.

Although the relevant content of qcd summation rules has not been fully solved yet.

But Chen Zhou didn't intend to be so immersed in it that he didn't even know Yang Yiyi came in like he was at noon.

Chen Zhou thought, hurrying to have dinner and take a walk around the campus.

Then, come back and bury your mind in mathematics.

"Yiyi?" Chen Zhou turned around and looked to his side. Yang Yiyi was sitting on another desk, burying her head in writing something.

Hearing Chen Zhou's voice, Yang Yiyi turned to look at him in confusion.

Chen Zhou smiled softly and said, "Want to eat?"

Yang Yiyi glanced at the time, then nodded belatedly: "Oh, okay..."

After dinner, Chen Zhou and Yang Yiyi held hands and walked on the MIT campus.

Just like when I was studying at Yanda University.

The two of them have hardly changed.

Chen Zhou looked at the Massachusetts Avenue in front of him and felt a little emotional in his heart.

The entire MIT campus is basically divided into two parts from north to south by Massachusetts Avenue.

The west side is mainly student dormitories and living areas.

The east side is the teaching and research experimental area.

Walking on this road made Chen Zhou feel that this is the essence of life.

One hand is life and the other hand is learning.

As if aware of Chen Zhou's subtle emotions, Yang Yiyi tilted her head and asked softly: "What's wrong with you?"

Looking at his lovely girlfriend beside him, Chen Zhou immediately calmed down and said with a smile: "Yiyi, let's go and see the place that is both the Harvard Bridge and the Mitt Bridge?"

Yang Yiyi nodded slightly, smiling slightly: "Okay, let's go."

This is the closest bridge to the MIT campus.

It is an iron bridge spanning the Charles River.

Therefore, it is connected to Harvard University and MIT.

Therefore, it is called both the Harvard Bridge and the Mitt Bridge.

Standing on the bridge, Chen Zhou looked at the Charles River.

If this were done in China, this river would definitely have countless students coming to make a "pilgrimage".

I hope I can get a little bit of "the spirit of a master of learning".

Suddenly, Chen Zhou thought of an interesting anecdote about this bridge.

Immediately, Chen Zhou deliberately walked to one end of the bridge, raised his arms, and stretched them out.

Then based on the length of the armspan, the length of the iron bridge was measured.

Yang Yiyi looked at Chen Zhou's funny actions and said with a smile: "What do you want to do? Do you also want to create a new unit of length?"

Chen Zhou stopped his movements and asked slightly surprised: "Do you also know this interesting story?"

Yang Yiyi winked at Chen Zhou and said proudly: "Of course, my sister knows everything~"

Chen Zhou stretched out his hand and rubbed Yang Yiyi's head: "I didn't even praise you, so you're just arrogant?"

Yang Yiyi snorted: "Then why don't you praise me quickly?"

Chen Zhou looked at the cute and innocent look of this girl, deliberately pretending to be serious, thought for a while, and then said: "Then tell me?"

"Then do you listen well?"

"Okay, please let Teacher Xiao Yang start teaching!"

"Well...Classmate Xiao Chen, please listen carefully..." Yang Yiyi deliberately cleared her voice and said slowly, "The bridge captain of this iron bridge is the famous 364.4 'smooth'."

"As for the meaning of this length, it comes from 1958, Olivier R. Smoot, a student at MIT."

"At that time, Smoot wanted to create a unit of length called 'smoot'. So he whimsically used his own body to measure the length of Harvard Bridge."

"A 'smoot' here is equal to 170.180 centimeters, which was Smoot's height at the time. And his final measurement result was the famous 364.4 'smooth'."

When Yang Yiyi finished speaking, Chen Zhou smiled and praised: "Okay~ Teacher Xiao Yang, that's great!"

Yang Yiyi was naturally very grateful for Chen Zhou's praise.

After a while, Chen Zhou suddenly asked: "Is Smoot really crazy?"

Yang Yiyi was stunned for a moment, not knowing how to answer this question.

Is Smoot really crazy?

I'm afraid you have to ask Smoot himself to find out.

But at least, this whimsy allowed him to do something that no one else had done.

Therefore, it left a little trace in history.

Chen Zhou turned to look at Yang Yiyi who didn't know how to answer, and laughed softly: "Let's go back."

After that, he pulled Yang Yiyi and walked towards the apartment building.

Chen Zhou didn't expect that Yang Yiyi could give an answer to this question.

Chen Zhou didn't just ask Yang Yiyi this question.

At the same time, he was also asking himself.

Throughout history, whether it is mathematics, physics, or other disciplines.

There is no shortage of imaginative people.

And those brilliant and great theories are also inseparable from a moment of whimsy.

Of course, if you really want to say it, this kind of whimsy is whimsical, but it is not completely whimsical.

Take mathematical conjectures as an example. Every mathematical conjecture is based on a certain degree of rationality.

Based on this kind of rationality, let’s go “whimsical”.

For example, after returning to the dormitory, Chen Zhou began to study Goldbach's conjecture.

Although the establishment of this project was reported to the science and technology department before coming to MIT.

However, Chen Zhou has been thinking about Goldbach's conjecture for quite some time.

Goldbach's conjecture originated from a letter written by Goldbach to Euler in 1742.

The content of the letter is the famous Goldbach's conjecture.

Originally, Goldbach thought, he couldn't prove it.

Euler, the famous mathematician, should be able to solve it.

But I didn't expect it until Euler passed away.

He also failed to prove Goldbach's conjecture.

Until today, nearly 300 years have passed.

No one has given the final proof of Goldbach's conjecture.

This problem has also become one of the three major mathematical problems in modern times in the world.

Now, Chen Zhou has set his sights on this problem.

After spending the day doing physics.

In the evening, Chen Zhou planned to start with Ge Guai.
