After Chen Zhou completely pinched off what he had and felt good about himself.

Then he was engrossed in the theoretical calculation of the quality of the rubber ball by using the QCD summation rule.

Chen Zhou's plan is to divide the day into physics and mathematics at night, focusing on the theoretical knowledge of rubber balls.

Wait until the rubber ball theory of these conventional quantum numbers, and the rubber ball theory of those strange quantum numbers, are all clear.

Then adjust the plan to rotational mode.

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

The evening is also counted as half a day, and it rotates in turn.

Of course, this kind of rotational mode of learning and research is not inevitable.

If a train of thought isn't open, always immerse yourself.

Then, time will automatically move back.

The reason for this arrangement was that Chen Zhou did not want that possible, fleeting inspiration to be interrupted by a blunt plan that was not entirely necessary.

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

Although the relevant content of the QCD summation rules has not been fully resolved.

But Chen Zhou didn't plan to do it again, like at noon, and he didn't even know that Yang Yiyi came in.

Chen Zhou thought, hurry up to dinner, and still walk around the campus.

Then, come back and bury your mind in mathematics.

"Yiyi?" Chen Zhou turned his head to look at the side, Yang Yiyi was on another desk, burying his head in writing.

Hearing Chen Zhou's voice, Yang Yiyi turned her head and glanced at him suspiciously.

Chen Zhou smiled softly: "Going to dinner?"

Yang Yiyi glanced at the time, and then nodded consciously: "Oh, it's ......."

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

Just like when I was a student at Yan University.

The two of them, almost unchanged.

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

The entire campus of MIT is basically divided in two by the Massachusetts Avenue from north to south.

The west side is dominated by student dormitories and living quarters.

On the east side is the teaching and research area.

Walking on this avenue, Chen Zhou feels that this is the essence of life.

One hand is life, the other hand is learning.

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

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

Yang Yiyi nodded lightly, and smiled lightly: "Okay, let's go." ”

This is the closest bridge to the MIT campus.

It is an iron bridge that spans the Charles River.

As a result, Harvard University and the Massachusetts Institute of Technology are connected.

Therefore, it is called both Harvard Bridge and MIT Bridge.

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

If this is left in the country, this river, there will definitely be no math students, come to "pilgrimage".

I hope to get a little bit of "academic tyrant".

Suddenly, Chen Zhou thought of an interesting fact about the bridge.

Immediately, Chen Zhou deliberately walked to the end of the bridge, raised his arm, and stretched it out.

Then, relying on the length of the reach, the length of the iron bridge began to be measured.

Yang Yiyi looked at Chen Zhou's antics and said with a smile: "What are you going to do? You also want to create a new unit of length?"

Chen Zhou stopped his movements and asked with a little surprise, "Do you know this anecdote too?"

Yang Yiyi squeezed her eyes 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 praise you, you just floated?"

Yang Yiyi snorted: "Then don't you hurry up and praise me?"

Chen Zhou looked at this girl's cute appearance, deliberately pretended to be serious, thought about it, and then said, "Then tell me about it?"

"Then you're listening, huh?"

"Okay, please start teaching!"

"Hmm...... Xiao Chen, please listen well......" Yang Yiyi deliberately cleared her voice and said slowly, "The bridge length of this iron bridge is a little more and a little less of the famous 364.4 'smooth'. ”

As for the meaning of this length, it comes from 1958, a student at the Massachusetts Institute of Technology, Olivan Brown. R. Smoot. ”

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

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

After Yang Yiyi finished speaking, Chen Zhou praised with a smile: "It's okay~ Teacher Xiao Yang, awesome!"

For Chen Zhou's praise, Yang Yiyi was naturally very useful.

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

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

Is Smoot really whimsical?

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

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

Therefore, in history, a little trace has been left.

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

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

Chen Zhou didn't think about this question, Yang Yiyi could give an answer.

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

At the same time, he was asking himself.

Throughout history, whether it's mathematics, physics, or other disciplines.

There is no shortage of whimsical people.

And those glorious and great theories are also inseparable from whimsical moments.

Of course, if you really want to talk about it, this kind of whimsical is not entirely whimsical.

Take mathematical conjectures as an example, every mathematical conjecture is based on a certain degree of plausibility.

On top of this rationality, go to the "whimsical".

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

Although the project was approved before coming to MIT, it was reported to the science and technology department.

However, Chen Zhou's thinking about Goldbach's conjecture has been going on for a long time.

The Goldbach conjecture stems from a letter Goldbach wrote to Euler in 1742.

The content of the letter is the famous Goldbach conjecture.

Originally, Goldbach thought, he could not prove it.

The famous mathematical god Euler should be able to solve it.

But I didn't expect it, until Euler died.

He also failed to prove Goldbach's conjecture.

Until today, it has taken nearly 300 years.

The final proof of Goldbach's conjecture has not been given.

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

And now, Chen Zhou has set his sights on this problem.

After spending the day's physics.

Chen Zhou in the evening planned to start with Gechai.

Have a good time with your own math.
