After the time difference, Su Xiaomu's contact with China is no longer as convenient as before.

It's like now.

After lunch, Yi Ran and Chen Jiming drank tea and gossiped for a while, then left the townhouse together and went back to the apartment that was also ten minutes away.

Su Xiaomu glanced at the time on his phone, it happened to be three o'clock in the afternoon.

When it comes to time, it's hard for Soho and Wan Dai.

After coming to the United States, he bought a few more watches for Su Xiaomu.

There are also special matching occasions.

It's a pity that Su Xiaomu hasn't worn it once.

"It's three o'clock......" Su Xiaomu sighed inexplicably.

I swiped my phone away, looked at it, and threw it aside.

The mobile phone screen clearly shows the time of Beijing @ Beijing: four o'clock in the morning of the next day.

Su Xiaomu looked up at the ceiling.

I thought to myself if it was usual, what would I be doing at this point in time when there were no classes?

Soon there was an answer.

Run errands.

or in a company.

It's either to meet different people, or to meet people you want to meet.

Someone can always see.

But in the United States......

After a long time, Su Xiaomu got up and took the car keys and went out.

Aimlessness may be an additional way of life in the United States later on?

…………

Yangcheng.

Four o'clock in the morning.

Quiescence.

Occasionally, the sound of rustling sounded in the streets.

Dressed in orange vests, they were clearing the streets step by step.

The small restaurant on the street had already begun to prepare breakfast, behind the slightly lighted roll-up doors.

There are still some people who don't want to end yesterday's wasted day and are still scrolling through their mobile phones, computers, and everything.

There are also people who have just finished working overtime and are on their way home.

There is a good saying, in this huge city, who is not desperate to move forward in this huge city?

The top floor of a residential building with more than 20 floors suddenly revealed bright light.

Soho, dressed in pajamas, sat up from the bed, next to Wan Dai, who sat up almost at the same time.

"What's wrong with you?"

"Are you ...... too?"

"Alas......"

"I wonder how a dead ghost is doing in Massachusetts?"

"Why did you still run into a dream?"

"It's afternoon over there, so I guess it's class, right?"

"I don't think there will be classes in the afternoon, and today is the first day of classes. ”

"I'm going to find a timetable tomorrow. ”

“……”

"Sleep. ”

"Sleep. ”

"Three hours to go......

"yes......"

The lights came on and off, and the sound of breathing did not settle down.

The sound of tossing and turning continued and continued to sound......

…………

…………

In the morning class the next day, Su Xiaomu was invited to the podium again.

This time it's a probabilistic system analysis.

It is a course that compares MIT.

Because it is a courseware written by MIT professors, it is a professional basic mathematics course.

Like Professor Hills yesterday, after briefly introducing some terms in the course as an opening remark, the professor gave a direct question in class.

An example of a discrete and infinite sample space.

In mathematics, there is always something interesting.

Many people, especially students in China, are likely to trigger an event in their high school career:

I dropped a pen.

Bend down and pick it up.

Look up at the blackboard.

The blackboard is full of calculations and characters, and it is like a ghost drawing that I can't understand anymore.

Since then, mathematics has gone from meeting and knowing each other to being separated from each other, and getting farther and farther apart.

In fact, Su Xiaomu did not show any talent or extra excellence in mathematics-related fields.

Although since junior high school, mathematics has increasingly begun to divide students into scumbags, Su Xiaomu has scored all the way.

Even at the undergraduate level, there are always full marks in several categories of higher mathematics.

However, these are not exceptions.

When the professor asked a question, Louis and the others quickly set up a stage for Su Xiaomu to perform.

And made the action of please start your performance.

"Sue, there's nothing we can do, maybe you can try?"

"Basic math related to your major should not be difficult for you!"

“……”

Su Xiaomu looked at Louis and the others who were coaxing, and was a little speechless.

I'm not a genius?!

How can I possibly understand everything?

I whispered in my heart: "Could it be that Americans are so good at playing?"

Of course Su Xiaomu knew about this kind of thing when he picked it up and fell down.

However, looking at the countless eyes in the classroom, Su Xiaomu couldn't refuse directly.

I had to tell myself that on other people's territory, I wanted to show the excellent demeanor of the Chinese!

"I'll try. Su Xiaomu said.

Everything that followed was not much different from what happened yesterday.

Su Xiaomu quickly wrote down three simple but important axioms on A4 paper, from which many other theorems can be derived.

"I probably have the answer......"

Su Xiaomu stopped the pen in his hand, turned the pen flower with his hand, and looked at everyone.

"It is well known that these three axioms lead to some important inferences, such as: ......"

Su Xiaomu said, and quickly wrote a line of determinants on the whiteboard.

"It's a simple process, so I won't say much about it. ”

"We all know that there are ways and steps to calculate probabilities......"

Brush brush brush, and a few lines of extremely beautiful board book.

When it comes to writing words, Su Xiaomu is also very handy.

“…… The addition of conditions may affect independence...... But that's what we need to solve. ”

“……”

"Okay, that's all the way to solve the problem, and in practical application, you can still continue to simplify some relatively simple and popular operations that can be omitted......"

After Su Xiaomu finished speaking, he put down the whiteboard marker in his hand.

The classroom burst into applause.

Su Xiaomu silently returned to the crowd.

Suddenly realize that this is very wrong.

"What am I here for?"

Su Xiaomu asked himself in his heart!

The answer was quickly reached: exchange and learning!

"And what am I doing now?"

"Lecture!"

“MMP！！”

"The style of painting is wrong!"

Su Xiaomu realized this fact that he had to accept and admit.

He came to MIT for exchange learning, but now he hasn't learned anything......

Light is giving a lecture!

He was even a little skeptical, could this be the American academic style?

In the morning, there is only this class on probabilistic system analysis.

In the afternoon, there is a comprehensive laboratory class.

In layman's terms, it is...... Take a computer-based lesson.

The method is similar to that of the big classes in China, and there are students from other classes who take classes together.

Su Xiaomu ran into Kevin, Allen and others, including Liu Yang, and also met Jeffrey.

Several people took the initiative to find Su Xiaomu.

Bringing an older man wearing glasses, Alan introduced, "Sue, this is my cousin, Josie, a doctoral student at this school. ”

"It was also our companion to this class. ”

Su Xiaomu greeted with a smile: "Hello Mr. Josie, I'm Su Xiaomu." ”

Josie laughed too......
