In mid-September, the weather is still so hot.

A handsome young man was standing next to a corner of a cafe, thinking about the meaning of life and the mystery of the universe with melancholy.

His name is Fang Xun, and he traveled through time. In his previous life, he was a physics genius. He was admitted to the junior class of a well-known university at the age of fourteen. After graduating from undergraduate studies, Harvard University provided Fang Xun with a full scholarship and finally chose Princeton.

Fang Qing has lived up to expectations and became an assistant professor in the Department of Physics at the age of 23. His main research directions are cyclic quantum gravity theory, supersymmetric bonding states, black hole entropy, etc., and are one of the young physicists who are highly anticipated by the international physics community.

At the age of 25, Fang Shi chose to return to China. Although the process was a bit bumpy, he still came back. He never expected... He traveled through time the second year after returning to China. How did he travel? Why did he travel? Fang Shi thought that he might have accidentally triggered Einstein-Rosen Bridge.

"Wormhole..."

"Since it really exists, according to the relativity model... negative energy is needed to maintain the state of opening the wormhole. Even so... how do you extract negative energy?"

"Extracting negative energy alone will undoubtedly reduce the entropy value in space. Doesn't this just violate the second law of thermodynamics?"

Fang Qingnu nodded, and he found himself entering the minefield in the laws of physics, and his journey through time was always a mystery.

Putting aside these unexplained questions, when I first traveled, I was not a soul traveling through time, but a whole person traveling through time. What is magical is that I have an identity in this strange and familiar world.

——Orphan started with a master's degree in physics at a certain university, and then he was unemployed at home.

This situation...it can also be explained that in chaos science there is a primary sensitivity dependency called the initial value, which is a general behavior of nonlinear dynamic systems and a reflection of the inherent randomness of the deterministic system. The slight differences in the initial conditions will make huge differences in the end.

Your own time travel will undoubtedly break the balance of time and space, and will naturally trigger a chain reaction, and eventually this unexpected result will occur.

The first thing I did after traveling through time was to find a job. Perhaps it was God's mercy. I found an internship researcher position in an affiliated research institute of a first-class university. Before the official report was reported, Fang Shi had already planned his life.

Become an expert in one year, go to the Academy of Sciences for two years, and win the Nobel Prize in three years!

The result...the reality is so cruel.

It's been half a month since this is done? Basically, I'm doing physical labor, either moving equipment or cleaning, but I haven't been exposed to serious research content.

There is no way. The boss who followed him was an associate researcher who was postponed for the second time. He was about to be 70 years old and was facing retirement again. Therefore, the project in his hand was progressing slowly for at least 300 days a year, and there was no progress for the other 65 days. This is just a theoretical model. The experimental part is to screw screws at least 300 days a year, and the remaining 65 days are to worry about what to do next.

Of course, there is also an advantage, that is, it is particularly relaxed in performance appraisal. After all, there is only one tool in the entire project team, and that is yourself.

"Why..."

"The limit distribution of asymptotic normal random variable function..."

"Are you not studying the conjunction and asymptotic normality of random variables? How can I study this topic? Are you deliberately making things difficult for me?"

The sudden mathematical term brought Fang Shi's thoughts back to reality. Looking at the source of the sound, a young woman wearing black-framed glasses was sitting at the table opposite her, holding a document in her hand, looking sad.

Although she tied her ponytail, she still looked a little messy, probably more casual when tying her hair, and this casualness was reflected on her face, and there was no trace of makeup.

However, even so, it is still impossible to conceal the naturally revealed softness, even if there are these bulky black-framed glasses.

"Maybe this is not a difficult thing."

"In the inference problem of unknown quantity functions, it is necessary to know that the estimation of the unknown quantity has asymptotic normality, and then make a judgment on its limit distribution. Therefore,... the limit distribution of the asymptotic normal random variable function becomes extremely important."

Fang Qi sat on the chair and said casually to the woman opposite.

As soon as the words fell,

The woman suddenly raised her head and looked at Fang Qing in the voice. The two of them had their first contact with each other.

"You can try to derive the limit distribution of the random variable function from the asymptotic normal random variable, and you can probably get the asymptotic normality of the square root in the Poisson random variable and the asymptotic normality of the random variable part and the asymptotic normality of the random variable under the normalized constant."

Fang Shi said this and couldn't help but pause, and then said: "Of course... this process will be very complicated. It requires combining multiple mathematical theorems to prove the final result. It may be a bit difficult for you to say it. Uh... I think you'd better give up and study some simple topics."

In an instant,

The young woman's mentality exploded.

At first she was so flattered that she didn't expect that her complaint would be heard by a strange man, nor did she expect that this strange man who heard her complaint would give him a solution that seemed to be able to solve the problem. Although... he looked like a second-rate man, especially his half-dead appearance, it is undeniable that what he said was very professional.

However...

Unexpectedly, in the end he...he actually questioned his strength.

So angry!

I... a PhD in mathematics who graduated from a high school degree in Paris, actually... was questioned about lack of mathematical ability?!

"Hello!"

"I'm..."

Before he could finish his words, he watched him pick up his cell phone, then turned around and left the cafe until his back disappeared from sight.

After a long time,

The young woman reacted, stood up, hurriedly ran out of the cafe, standing at the door, looking for the back, but at this moment... the figure of the man had long disappeared.

The more I thought about it, the more angry I became, I couldn't help but kick the lamp post on the side of the road, and instantly put on the mask of pain.

It hurts so much...it hits my toes.

...

...

"Hello?"

"Auntie Wang? Is there anything wrong?"

On the other end of the phone is Fang Shin's boss, the wife of Aunt Wang, the retired associate researcher Yu Huazheng...

"Xiao Fang..."

"I remember you seem to be twenty-six?" A kind voice came from the other end of the phone and asked with a smile.

"Um."

Fang Ye responded casually.

"Do you have a girlfriend?" Aunt Wang continued.

"In the case of mine, it's still a bit difficult to find a girlfriend, so let's talk about it later." Fang Shi replied bitterly.

"Young people don't be so pessimistic."

"No one can say anything like fate." At this point, he paused and then said, "Come to your Aunt Wang's house to have dinner in the evening. Remember to dress up handsomely."

After saying that,

Doodle...

Just hung up.

At this moment, Fang Qi was holding his cell phone and standing in the scorching sun, his face full of confusion.

What's going on?

It feels full of conspiracy.
