For the next few days, Han Yi soaked in the library of Jinling University.

Physics, Astronomy, Meteorology, Electronic Information, Optical Information, Environmental Science, Polymer Materials and Engineering, Thermal and Power Engineering, Communication Engineering, Biomedical Science and Engineering, all kinds of things.

His strong memory has given him the ability to memorize, and after reading everything once, it seems to be engraved in his mind, and he can call it up at any time.

But the consequence of this is that his physical consumption has increased dramatically.

The main activity of the human brain is the transmission of signals by neurons through the movement of electrons, as well as the maintenance of the membrane potential of neurons, although its weight is only about 2% of its body weight, but it consumes more than 25% of the overall energy consumption.

And that's just the normal thing.

And the learning intensity like Han Yi's, that is not 25%, but 250%, more than ten times.

Originally, an energy capsule that could sustain a day of high-intensity exercise, he now basically has to take one every 1 hour, otherwise the whole person will collapse.

......

soaked in the library for a whole week, until Shen Xin called and asked him when he was going to Nanjun Island, Han Yi slowly closed the "General Theory of Electromagnetism" in his hand.

I was going to go back to Jiangxin Island, but I changed to Yulan Garden halfway.

Before entering the door, Han Yi thought of "Lano's Turtle", one of the four great divine beasts in the physics world, and then thought of the gap between the earth and extraterrestrial civilizations.

Lanor's tortoise means that if you have a tortoise in front of you and you set off at the same time as it, then you must first get to where it came to be if you want to overtake it, and then it has gone some way forward;

Then you continue to chase and must reach where it is at this moment, at which point the turtle has gone some way forward. You'll never be able to catch up with that turtle.

Of course, this problem has already been solved by the calculus created by Newton and Leibutsny.

The so-called "forever" should be the infinity of time, not the limit of time approaching a certain number, and the Rano tortoise can only prove that when time is infinitely close to a certain value, my travel distance is "always" less than the tortoise's travel distance.

Always is not the same as forever!

So can this law be applied to extraterrestrial civilizations? Can he also become the "Achilles" who surpasses the thousand-year-old tortoise?

This question was still lingering in his mind, and when the security door opened automatically, Han Yi thought of "Laplace Demon", one of the four great divine beasts in the physics world.

A scientific hypothesis proposed by the French mathematician Pierre-Simon Laplace in 1814: "We can regard the present state of the universe as a consequence of its past and a cause of the future."

If an intelligence knows the forces of all natural motion and the position of all naturally constituted objects at a given moment, and if he can also analyze these data, then the motion of the largest object to the smallest particle in the universe will be included in a simple formula. ”

To put it simply, if anyone can crack this "demon", then he will be able to know the exact position and momentum of each atom in the universe, and will be able to use Newton's laws to show the entire process of cosmic events, the past and the future.

For example, by measuring the impact of electrons and photons in the air, he can know whether Song Yunxiang is in the house or not, her ideology, and even her thoughts.

Because thought is also a manifestation of electronic movement.

Isn't it terrifying?

......

......

I've seen Tang Bohu light mosquito coils...... Do you want to make autumn incense?

Tang Bohu found 7 wives and played mahjong at home every day, and then he met Qiu Xiang, a maid who thought he knew him very well, and finally married Qiu Xiang home after 9981 levels.

However, Tang Bohu is still too naïve, Qiu Xiang, who admired his talent before and read "Peach Blossom Nunnery in Peach Blossom Dock" in a daze, just got together two tables of mahjong after getting married......

As for the poetry collection, it was taken to the table legs.

This story is not to show us how fickle women are, but to show us that before and after marriage are two different things.

Of course, Song Yunxiang is not so exaggerated. In fact, she has not been completely captured by Han Yi, but the temperament of "clear water in the snow river, quiet people in the empty valley" on her body has still been broken.

When Han Yi entered the door, Song Yunxiang was wearing plain home clothes, with an apron tied around her waist and mopping the floor in the living room, and the painting style made him unbearable to look at it directly.

In his impression, Song Yunxiang is the kind of peerless beauty who does not eat the fireworks of the world, she should talk to people about poetry and songs, or wear a dust-free suit and bury her head in the laboratory, and be the "sweeping monk".

"Why do you have time to come over?" asked Song Yunxiang, who was pouting her buttocks, without turning her head.

Han Yi stood beside the iron tree around the corner, picked up the water bottle and sprayed, "I'm going to New Zealand." ”

"Oh~ I thought you came to ask me why I didn't go to the research institute!" Song Yunxiang said without a trace of fireworks.

Han Yi didn't like her tone, put down the kettle and walked behind her, and then slapped her ass with a "snap".

Song Yunxiang was like a cat whose tail had been stepped on, jumping far away, turning her head and staring at him in disbelief.

That expression was like seeing a prehistoric pervert.

Han Yi's face did not change, sat on the sofa and said, "Don't delay, I'll help you find a new house." ”

Last time, I thought about letting Song Yunxiang live temporarily, but I forgot about it.

Song Yunxiang hesitated for a moment, then put down the mop and walked to the sofa opposite Han Yi and sat down.

"I want to go to New Zealand. ”

"Why?"

Song Yunxiang turned her head to look at the pines and cypresses in the garden outside the window and said, "I am very awkward in China. ”

Han Yi nodded.

He feels like he's taken another big step toward "scum" now.

I thought about it and said, "That's fine." I'm planning to build a large research institute on the South Island, so you can take care of it for me. ”

Song Yunxiang turned her head to stare at him, "You...... Pull me back to do things for you?"

"Nonsense...... Of course not. ”

After a pause, Han Yi followed: "Between people, in addition to mutual attraction, they must also have common interests and hobbies, so that they can go longer and farther."

I'm not just talking about thirty or fifty years of human life. ”

"How long is that?"

"At least 28 centimeters. ”

"......" Song Yunxiang felt that she couldn't talk about it this day.

Han Yi especially likes to see Song Yunxiang's speechless expression.

Those who are close to Zhu are red and those who are close to ink are black, maybe this is training.

No, it's more appropriate to use "flirtatious".

......

was supposed to leave that afternoon, but Song Yunxiang's father called her and asked her to go back.

Han Yi thought about it and followed.

Song Yunxiang's family is in Haidao City, Zhejiang Province, and the family is also an only child, and her parents are indeed ordinary employees of enterprises and institutions, but her grandfather is different, many years ago he was a famous professor in the Department of Mathematics of Zhejiang University, and has published many influential works.

It's a pity that Song Yunxiang died when she was 5 years old.

Therefore, part of Song Yunxiang's talent is inherited from generation to generation.

At five o'clock, when Han Yi and Song Yunxiang came to the door, Song Yunxiang's father, Song Yu, a middle-aged man wearing gold-rimmed glasses and looking like a scholar, almost didn't have his eyes startled.

"This is ......," Song Yu asked, looking at his daughter.

Song Yunxiang was a little embarrassed, she really didn't want Han Yi to come over, he had to follow him with a cheeky face, and he used some despicable means to force her to comply.

"Hello uncle, my name is Han Yi. Han Yi introduced himself.

"Also...... It's really true~" Song Yu was also very surprised, "That ...... Mr. Han, you sit. Xiangxiang, quick, pour tea for Mr. Han to ......"

"Oh~" Song Yunxiang answered and went to the kitchen. Although Han Yi came uninvited, he was also a guest.

Here, Han Yi sat down and smiled, "Why haven't you seen your aunt?"

"Hehe, her unit has something to do today. Saying that, Song Yu said enthusiastically: "Mr. Han, you eat fruits." ”

"Hey, I'll do it myself......"

After sitting for less than half an hour, Song Yunxiang's mother came back.

After knowing Han Yi's identity, he was naturally surprised. Song Yunxiang never told them that she knew Han Yi, let alone the relationship between the two.

The mother and daughter entered the room and came out again about ten minutes later.

"Xiangxiang, you accompany Xiao Han to go out for a walk, and come back for dinner later. ”

"Oh~" Song Yunxiang walked up to Han Yi and said, "Let's go." ”

Han Yi knew that the two of them were going to whisper, so he followed Song Yunxiang out of the door with great interest.

He came over today to protect Song Yunxiang's parents. After all, it is a big deal for my daughter to go abroad, so I always have to know who I went with?

Song Yunxiang's house is the kind of self-built small bungalow with a courtyard house, but it has been around for some years.

The two walked along the cement road in front of the door towards the district commercial street in front. This is the west of the city, some distance from the city center.

After walking for more than ten minutes, seeing that Han Yi had been silent, Song Yunxiang couldn't help but say, "You don't want to know what my mother said?"

"Well, what did you say?"

Seeing his casual appearance, Song Yunxiang was a little lost, "It's nothing!"

Han Yi felt that he was now about to practice "his heart", and Song Yunxiang knew what she was thinking as soon as she pouted.

But she didn't bother to explain it, because soon she would no longer bother with these little things.

The vast sea of stars is waiting for them to conquer, and the matter of affection is really insignificant.

There happened to be two big winters in front of him, wearing jeans with a very low waist, revealing a white water snake waist.

Han Yi gestured with his jaw to the crystal chain on the waist of one of the girls and asked, "Do you know why the chain is hung?"

Song Yunxiang followed his line of sight and shook her head, "Why?"

Han Yi said in a professional tone: "It means that there is one thing on the body after taking off your clothes, and you will not be naked, which is the last dignity of employees in special industries." ”

Song Yunxiang: "You ......"
