Undecided in the face, quantum mechanics [Wear the book]
Chapter 132: An Epiphany
Ying Jianliao has now fully reacted.
He felt his heart beating a little faster.
After reacting, Ying Jianliao felt more and more... The original owner is definitely not a simple person.
The logo on the clothes was cut off by the original owner.
The purpose is to exclude the interference of other factors.
In this way, the only information that can be provided on the clothes is the fabric and color, and other information about words and letters will not be provided particularly much.
And the color of the clothes...
Ying Jianliao looked at the color of the clothes, and said in a low voice——
Pink, teal, blue, thistle.
pink, aqua, bule, thistle.
After reading, the corner of Ying Jianliao's mouth slightly raised a small arc.
This information provides... simply fantastic.
Seeing the color, it may be difficult for outsiders to perceive the mystery and logic in the color, but Ying Jianliao feels that the provision of this information is wonderful...
This logic may not be thought of by others, but it is completely in line with their own cognitive level.
It can even be said... that he followed his own way of thinking completely.
Ying Jianliao felt a sudden chill on his back.
This also confirmed Ying Jianliao's conjecture just now——
The original owner who can set this password is definitely not a simple person.
He felt that the most frightening thing to think about this matter was the degree to which the original owner knew himself.
——This information hints that other people may not think of it, or even say that they must not think of it, but according to Ying Jianliao's thinking logic, it is definitely possible to think of it.
Therefore, even if someone finds the hint information hidden in it, they will not find out what information is in it, and the so-called "hint information" placed in the memo, even if all the clothes are taken away, what will be noticed? He himself can still be inferred based on the information in the memo.
Ying Jianliao almost wanted to applaud this design.
The person who designed this designed it completely according to his own thinking and logical habits.
The initial sound of each word, the composition formula——
p=a+bθ.
The formula for the Archimedes spiral.
Another Archimedes spiral.
However, there is some difference that the X and Y axes are clearly visible on the scratches, which are Cartesian coordinates, and now you get the formula in polar coordinates.
Conversion.
Ying Jianliao looked at the scratches on the cabinet and the clothes he had taken out, and suddenly became enlightened again.
Even laughing inwardly.
--I see.
As for the data inside...
It's even more obvious.
There is a sweater with numbers written directly on the front.
Then the total number of pieces on all the sweaters, the number of knots tied on the drawstrings of the sweaters...all need to be brought into the spiral equation to find the final point.
Thinking of the formula just now, everything else is not too difficult.
Ying Jianliao pushed it very smoothly.
After getting the data, he converted the polar coordinates into Cartesian coordinates, then brought in the data provided in the clothes, compared with a city map pasted next to the clothes, established the coordinates with his own home as the origin, and finally... came out of a point.
Ying Jianliao took the map and looked at the point.
This is an address.
This address ended up in a community called "City Garden".
Ying Jianliao frowned.
Ying Jianliao had no impression of this neighborhood, but he didn't feel that his deduction was wrong——
He has an intuition that the original owner set it up like this.
But... the address range of a community is really too large, and only such a piece of information is undoubtedly like looking for a needle in a haystack.
There must be other hints.
Ying Jianliao frowned and fell into deep thought again.
It seems to be stuck in a moment.
He thought about it, and suddenly his eyes lit up——
His difficulty just now was that he didn't know how to continue like this, and it seemed that he didn't have any additional information for himself to find, but now...
Ying Jianliao had a new idea——
Change your thinking, if you are yourself, how will you hide the information?
Will a new logical way be set up again?
How can it be safe and inconspicuous?
After opening his mind, Ying Jianliao found the construction plan of this community called "City Garden" on the garbage dump of the bookshelf.
He drew it again according to the Archimedes spiral just now, and finally got a detailed address.
B22, Building 1107, City Garden.
This is the address.
Ying Jianliao pursed her lips and took a deep breath.
Building 22 B1107, this number...Ying Jianliao knows it.
It can even be said to be so familiar that it can no longer be familiar.
B22, Building 1107, when I didn't wear it before, this was the address of my home.
It's just that Ying Jianliao's memory is a little fuzzy, as if the name of the community in his memory doesn't seem to be something like "City Garden".
Ying Jianliao could even remember the structure of the house and the combination lock at that time.
But this house was later sold because of my tuition fees at the time.
Ying Jianliao looked at this address, feeling a huge shock in his heart.
He always felt that he had traveled to the world in the book, but the recent incidents that happened one after another made him have great doubts.
For a moment he wasn't sure whether he was Zhuang Sheng Xiaomeng, or he was living in Rashomon.
I thought I was in a book, but... why is the world in the book so similar to reality?
Ying Jianliao was even a little confused——
Which side is reality, past or present?
Ying Jianliao looked at the familiar address and made up his mind to take a sneak peek by himself when he had time.
When he saw this address, his heart was filled with certainty——
There must be very important information in the address hidden by the original owner after all kinds of hardships.
Ying Jianliao just wanted to find some time to go there secretly.
Regardless of whether he could go in or not, Ying Jianliao also wanted to take a look.
Ying Jianliao had a strange intuition.
Let's not discuss this seemingly real and fake world, and I don't want to be so mysterious that I can't be in the original owner...
Ying Jianliao just wanted to know what was in the place where he used to live.
And why did the original owner take pains to hide such an address?
Just when Ying Jianliao was fascinated by his thoughts, the Internet was blown up again because of Ying Jianliao's operation.
The fact that Ying Jianliao was invited by Physics was unimaginable enough. Everyone was covering their faces and feeling pain, thinking about how to apologize to Ying Jianliao. Ying Jianliao's Weibo once again stunned everyone. up.
——Ying Jianliao declined the invitation of the Institute.
Ying Jianliao V: Thank you for your invitation. The Institute of Physics has always been the place I want to go, but as an artist, I may not have the conditions to enter your institute. In the days to come, I will study hard and do my best. Thank you for your attention and support.
Ying Jianliao's weibo immediately caused an uproar.
[Ying Jianliao, what does this mean?not going? ! ?What a shame you didn't go? ! 】
[Nonsense, Ying Jianliao is not stupid, doing research can make some money, of course it is not as cost-effective as being in the entertainment industry. 】
[Why do I think Ying Jianliao is quite sincere?It’s true that a junior high school education can’t get into the Institute of Physics, and celebrities can’t have privileges either…]
The matter of Ying Jianliao once again sparked a big discussion.
On the other side of the city, the hoarse voice looked at Weibo and laughed a few times, as if talking to himself, but also as if saying to the people around him: "Not bad."
"Still... quite obedient."
There was a bloodbath on the Internet, those who felt sorry for Ying Jianliao, those who defended the Institute of Physics, those who took advantage of troubled waters to advertise and sell courses... you name it.
But Ying Jianliao himself kept a mind--
He contacted the Institute of Physics and said that after the college entrance examination, he will definitely go to the Institute of Physics for an internship after he has the threshold. Now that everyone does not understand his research direction, entering rashly will lead to a decline in the public's perception of the Institute of Physics.
Jiang Chenghong later contacted Ying Jianliao and praised him for being very correct——
Most of the people in the institute are traditional academics. Except for those who specialize in quantum communication research, they don't welcome Ying Jianliao's parachute very much. Even some people who specialize in quantum communication are suspicious of Jianliao's scientific research level.
Ying Jianliao smiled and hung up the phone.
Institute solved, closet answers solved.
The conditions for touching the truth are gradually being met, and Ying Jianliao is on the way to find the so-called "truth", even forgetting her boyfriend Chu Jue.
Ying Jianliao was busy with these things for several days, and finally, when he received a call from Chu Jue one day, he remembered Chu Jue's boyfriend.
Ying Jianliao picked up the phone with some embarrassment, with a rising small ending voice, scratching Chu Jue's heart a little itchy: "Chu Jue?"
Ying Jianliao felt a little guilty when he thought that he was focusing on his own analysis recently, but didn't go to see Chu Jue, nor took the initiative to call Chu Jue.
Some rubbed their noses embarrassingly: "Are you busy recently? I'm a little busy recently, and I forgot to contact you..."
Ying Jianliao acted first, and explained the reason to Chu Jue before Chu Jue had time to continue asking.
"I've been busy with my career recently, I really want to take you home, really!" Ying Jianliao's tone was full of promises.
"Why did you reject the Institute of Physics?" Chu Jue's voice was low, and it came through the earpiece. The low voice seemed to resonate with his ears, and it was numb.
Chu Jue didn't ask what Ying Jianliao was up to recently, but just asked himself a question from a long time ago.
Hearing this question, Ying Jianliao was silent for a while without speaking.
Chu Jue added another sentence, with a trace of puzzlement in his low voice: "Didn't you always want to go?"
"Someone is threatening you?" Ying Jianliao's silence made Chu Jue understand what was going on, "Jiang Xiaohan?"
"Yeah." Ying Jianliao's voice was muffled, "You don't have to worry about it."
"I made an agreement with the institute, and I'm going to pass the exam."
"Okay." Chu Jue's voice slowed down.
"How are you doing recently? Are you busy? There are still a lot of announcements?" Ying Jianliao pretended to be casual and asked Chu Jue, "I haven't seen you much recently. I heard that you are on a business trip."
Ying Jianliao sighed embarrassingly, and the guilt in his heart kept coming out——
Get busy and forget about your boyfriend.
Chu Jue was silent for a while on the other side, smiled lightly, and replied: "Busy."
"Very good." Chu Jue's voice was still low, but with some complicated emotions.
"By the way, if you said I was going somewhere, no one would follow me, right?" Ying Jianliao asked Chu Jue what he thought of.
"Not now." Chu Jue answered quickly this time, "They are also very busy recently, and have no time to follow us."
"When we meet next time," Chu Jue's voice paused, as if he had made up his mind, "I'll tell you what I know."
Ying Jianliao agreed.
A silence fell between the two, so quiet that one could even hear the other's breathing.
"Chu Jue, I... miss you a little bit."
Ying Jianliao suddenly said something to Chu Jue.
Chu Jue was taken aback.
"I'll see you when I'm done."
There was a hint of a smile in the low voice.
"Well," Ying Jianliao's voice was muffled, "What if... I can't take you back?"
What he discovered in the past few days made Ying Jianliao feel a little confused.
Chu Jue gave a low laugh, and gave some irrelevant answers: "It's fine if I have you."
"Anywhere."
Ying Jianliao felt that Chu Jue's words were like a warm current, and his limbs and bones felt a little warm.
"Wait," Ying Jianliao also smiled at Chu Jue, "waiting for your return."
"I'm sure I can take you back," Ying Jianliao patted his chest, "When I get to the research institute, study hard."
Ying Jianliao made an oath to Chu Jue.
"Okay." There was a deep smile in Chu Jue's voice, "Wait for me to go back."
"Remember to learn Chinese."
Hearing Chu Jue's instruction, Ying Jianliao's face instantly collapsed.
"In the future, I will report my study progress every day." Chu Jue's expression still seemed casual, "Remember to call every day from now on."
Ying Jianliao felt both sweet and painful——
He sighed deeply, and muttered softly, "Got it."
The two chatted for a while, and Ying Jianliao, who was originally a little anxious, gradually calmed down during the chat with Chu Jue.
After Ying Jianliao repeatedly confirmed with Chu Jue that it was safer recently——
He decided to go out and go to the place where he got the information from the cabinet.
B22, Building 1107, City Garden.
Ying Jianliao stood in front of this door and took a deep breath.
The heart beats a little fast.
He looked at the door in front of him.
The same.
They didn't even change the couplets posted on the door.
The lock is a combination fingerprint lock.
When Ying Jianliao put his hand on the door, he could even feel his heart beating rapidly.
"drop--"
The door opened.
The author has something to say: Chu Jue: I am such a clever little ghost.
Ying Jianliao: The boyfriend instantly became the head teacher, afraid, jpg.

Hey, this is a bit hard to guess!
But everyone is so creative!There are so many I didn't expect! (Everyone is awesome too!
Continue to talk about spirals today!
[1] The constant velocity spiral is called "Archimedes spiral".
In the early phonograph, the motor drives the record on the turntable to rotate at a constant speed, and the grooves left on the record by the cartridge moving to the outer circle at a constant speed along a straight track are the Archimedes spirals.Similarly, the coiled mosquito coil produced by the uniform speed coiling machine is also in the shape of an Archimedes spiral.
Screws with equal pitch are also Archimedes spirals when viewed from the direction of the nail head, and mosquito coils are also Archimedes spirals.
[2] Another well-known type of spiral is called an involute.Many curves have their own involutes. Wind a thin, inelastic rope around a fixed circle, pull one end of the rope and straighten it so that the rope is always tangent to the circle. The trajectory of the end of the rope is the involute of the circle. Wire.
Involutes are active in the gears used for transmission by mechanical equipment.
[3] Equiangular spiral, its name comes from a famous mathematical problem: try to find a curve, the angle between the vector radius and the tangent at any point is a constant value.This problem was finally solved by Descartes in 1683.
Using a bit of simple calculus and a Cartesian coordinate system, we get the polar equation of the conformal curve: ρ=eaθ.Due to the presence of an exponential function in the equation, this spiral is also known as a logarithmic spiral.Due to its equiangular nature, the equiangular spiral is the most common spiral in nature.
The curves that the seeds of sunflowers and some other plants arrange on the disk are equiangular curves, so that each seed is minimally inhibited by the auxin secreted by other seeds around it, and at the same time they can maintain their shape when they grow. .The young leaves of ferns and some other plants also curl into logarithmic curves.
The shell curve of the nautilus is an equiangular spiral. This is because the amount of calcareous matter secreted by the inner and outer rings of the nautilus is always a certain value when it grows. The moths in flames and eagles in circles also move along the logarithmic spiral trajectory.
Fabre, the author of "Insects", once noticed that there are also logarithmic spirals in the webs produced by spiders, and even the name "logarithmic spiral" is called by Fabre~
Not only that, the shape of the spiral arms of the spiral nebula is very similar to the equiangular spiral, and the four major spiral arms of the Milky Way are equiangular spirals with an inclination of 12°.
Nature and Mathematics bordering again woo woo woo (keep shaking

woohoo
Stay up late again TUT
Tomorrow will be a worker again, woo woo woo, the wonderful holiday is too short!
good night~
感谢在2021-01-0317:39:05~2021-01-0401:16:28期间为我投出霸王票或灌溉营养液的小天使哦~
Thanks to the little angel who threw the mine: 1 Qingchen;
Thanks to the little angels of the irrigation nutrient solution: 5 bottles of soft Guangxi Fenda; 1 bottle of Luotang;
Thank you very much for your support, I will continue to work hard!

The shell curve of the nautilus is an equiangular spiral. This is because the amount of calcareous matter secreted by the inner and outer rings of the nautilus is always a certain value when it grows. The moths in flames and eagles in circles also move along the logarithmic spiral trajectory.
Fabre, the author of "Insects", once noticed that there are also logarithmic spirals in the webs produced by spiders, and even the name "logarithmic spiral" is called by Fabre~
Not only that, the shape of the spiral arms of the spiral nebula is very similar to the equiangular spiral, and the four major spiral arms of the Milky Way are equiangular spirals with an inclination of 12°.
Nature and Mathematics bordering again woo woo woo (keep shaking

woohoo
Stay up late again TUT
Tomorrow will be a worker again, woo woo woo, the wonderful holiday is too short!
good night~
