Chapter 2: Calligraphy of normal distribution

Views:

Zhang Heng ran seven laps around the playground, 2,800 meters.

After finishing his work, he went to the public bathroom to take a shower, changed into a clean white T-shirt and jeans, and ate breakfast in the cafeteria leisurely. library.

Like morning running, it is also one of Zhang Heng's habits, and he maintains a speed of one book a week.

However, unlike the morning run that was forced by his grandfather, it can bring him a lot of fun. It can be regarded as a kind of pastime, and he himself has always enjoyed it.

In fact, if it wasn't for the limited time, he would rather read a few more books every week.

After returning the book at the service desk, Zhang Heng took out his mobile phone from his pocket.

Opened a small program called Random Number Generator, set eight digits, and then... performed a roll point with great interest.

It must be admitted that it is not without reason that this guy is always considered a god.

Anyway, normal people who borrow books in the library will never be able to show this kind of coquettish operation of rolling and picking books.

But Zhang Heng has an advantage in reading books, or a quirk. It may be because he has read a lot of books since he was a child. He can read it with gusto, and his condition is still deteriorating. Today, he can even read "Compendium of Materia Medica" and "Handbook of Scientific Pig Raising". It is basically hopeless.

In order to avoid the trouble of choosing books and enjoy the pure joy of encountering good books, he created this set of normal distribution calligraphy selection method.

It is a pity that when applying for the campus scientific research award, unfortunately, it failed, and there was no fund for follow-up promotion.

So the capital market is always short of vision.

...

Zhang Heng rolled to the last two digits of the number and came to the corresponding bookshelf.

The luck this time is not bad, although it is not the literature category that was signed, but the management is also quite interesting, at least better than the "Waterwater, Heating, Gas Engineering Bill of Quantity Valuation" he rolled out last month many.

Stretch out your finger and pull out the goal for this time from the bookshelf.

—Adam Smith, The Wealth of Nations

Looks like it's going to be a good morning.

Zhang Heng found a seat by the window and sat down, then started his leisurely reading time.

Maybe some people can't help but complain when they see this, is that okay? Does he not care about his fine watch

Zhang Heng said that he really can't control this matter.

It is right to respond positively after the incident, but it has to be something that can be dealt with within your ability. Like this kind of supernatural phenomenon, when there are too few clues, maybe doing nothing is the most correct choice, don’t you see? In those classic horror movies, the instructors who turned around enthusiastically after being patted on the back in a dark old house all received lunch without exception.

On the contrary, you have to go all the way to the end calmly as if it doesn't exist, maybe it's just a trip to a haunted house with no danger.

Therefore, in many cases, calmness is the most important thing.

Zhang Heng is very calm now, you can never tell from his appearance that he is in the midst of a supernatural event, this guy used the time of skipping class to make up for his morning run, read The Wealth of Nations in the library all morning, and honestly went to it again in the afternoon The public elective course is critical thinking, and at night, I will fulfill my promise. I invite my bedmates to go to the food alley opposite the National University of Minnesota to eat barbecue skewers.

Then at 11:30, the dormitory was cut off on time.

Although Zhang Heng's laptop comes with a built-in battery, which can last for three or four hours, he did not disturb the rest of his sleeping brother and decisively turned off the power.

There is still half an hour before the end of the day, someone else's watch has already turned two times, but the hour hand of this familiar yet unfamiliar starfish in his hand is just about to complete a full circle.

will something happen? Zhang Heng didn't know, all he could do now was wait.

Zhang Heng put on the earphones, turned on the mp3, lay on the bed, and spent the remaining half hour of the day quietly.

00:00

The three hands coincided on time at the top of the dial, and they paused for a blink of an eye, after which the second hand continued to move.

Zhang Heng didn't notice anything abnormal during this period.

Was your guess wrong? He takes off his earphones.

But then something felt wrong.

Around - so quiet.

Summer nights are always extraordinarily lively, the small electric fan on the door creaks and shakes its head, the annoying buzzing of mosquitoes in the ear, the untightened faucet in the bathroom next door, the ticking of water dripping on the sink, the wild cat wearing The salsa from the flower garden downstairs, and of course the snoring from across the bed...

All this disappeared tonight.

The whole world seemed to have suddenly lost all sound and became unprecedentedly silent.

If it weren't for the indistinct singing voice in the earphones on his chest, Zhang Heng would even wonder if he had lost his hearing.

With the faint light of the mp3 screen, he looked at the time on the watch again.

It's 00:01

Usually at this time, the opposite dormitory is still playing lol online, and you can hear their cheers after completing a wonderful kill or extreme escape.

In addition to this, Zhang Heng also discovered another unusual thing. There is a date display on the right side of the starfish's dial. It is reasonable to say that the date on it should also change after zero o'clock, but this time it is still the same. stop yesterday.

Zhang Heng's heart skipped a beat, as if he had thought of something.

He didn't take off his clothes when he went to bed tonight, he just jumped off the top.

Turn on the computer, the boot process went smoothly, it took less than seven seconds, and the QQ login interface popped up by the way, but Zhang Heng's attention was not on it, his eyes moved down to the toolbar, the date and time on it Some dazzling.

00:00

September 20, 2017

Is it really the last moment of "yesterday"

Zhang Heng waited for a while. Instead of looking at the time on the starfish, he took his own pulse and counted two hundred times. According to his 72 beats per minute, at least two minutes had passed. The time on the phone still stops at 00:00.

Zhang Heng raised his eyebrows, but didn't rush to draw any conclusions.

He walked to the opposite bed and pushed Chen Huadong who was still sound asleep. The latter was the lightest sleeper in the dormitory. Usually, anyone who got out of bed at night and drank saliva would wake him up, but this time no matter how Zhang Heng pushed him Nothing happens.

"Sorry brother, although I don't have a girlfriend, I'm not the kind of person you imagine."

While Zhang Heng put his fingers under the opponent's nostrils, he was able to take some time in this weird atmosphere.

It can only be said that the psychological quality of this product is really good.

After five minutes, Zhang Heng could not feel the slightest breath.

If this is also part of the prank, then Chen Huadong's breath holding skill is too strong, he can go to the Guinness Book of World Records.

Since I have done it once, it is not bad for the second or third time.

Zhang Heng followed suit and tried it under the noses of the remaining two roommates.

The result was the same as Chen Huadong.

Zhang Heng can basically conclude that he has indeed encountered a supernatural phenomenon that cannot be explained by science.

He is now in a time that should not exist.

To use an analogy, it was as if the river of time had created a branch just for him.
