The solar system is broken

"Hmph!" Chuan Yuan curled his lips and groaned again while looking at the physics laboratory building of Jiangnan University.

The experimental building of Jiangnan University is in Yutong Garden, with many sycamore trees planted throughout the garden.

The bare sycamore trees, with their impressive hair, stood in a row.

The blue and white experimental building is built near the water, and its reflection on the sparkling waves is very picturesque.

"Did the dog mess with you?" The writer didn't understand why. This woman didn't feel right since breakfast.

"No..." Kawahara thought for a moment and shook his head, "Well, the dog messed with me."

The writer touched his nose and recalled that when he was eating in the morning, the native dog was watching him gnawing the ribs very seriously.

But why does it feel like Sichuan Yuan has eaten gunpowder and something is wrong when I wake up today? It's not normal.

Be a brave man and take her aunt away.

"Can I ask you a question?" Kawahara stopped, the writer's wheelchair in her hands.

"Yeah." The writer nodded, stretched out his hand, and caught a falling sycamore leaf, which was as big as three of his hands. "But you have already asked a question."

Kawahara was stunned, "Then can I ask you two questions?"

The writer nodded and folded the sycamore leaf over. The withered yellow veins simply cracked, and yellow fragments fell all over the writer.

"Congratulations, you have achieved two consecutive questions."

Chuan Yuan squeezed his palms, feeling that he could no longer control the anger in his heart.

She forced a smile and said, "Then can I ask you four questions?"

"Didn't you finish asking?"

"...Since when did I ask you four questions?" Kawahara lifted his fingers and counted, and there were indeed only three.

"Here, now."

...

...

Kawahara wanted to hit someone.

"Who asked you to insinuate and scold me?" The writer threw the sycamore leaf in his hand, and the leaf floated wildly and fell into a shallow puddle.

"Those things on your computer..."

The writer was startled and his wheelchair almost turned over with a creak.

"Did you click it?"

Although those things are all encrypted, for an information science person, passwords are actually nothing.

This is definitely a disaster. The cg of the otaku's guide to a good wife on the computer can't be counted with one pair of feet, and the learning materials can only be calculated using t.

The writer struggled and wanted to stand up and argue with Kawahara, but unfortunately it was not enough to break through the medical miracle. He fell down again.

"Well," Kawa Yuan glanced at his mouth, then blushed, "As expected, you men are all lustful."

Looking at Chuan Yuan's face, the writer's heart went cold. This was really what he saw.

"A normal man would do such a thing," the writer argued, "Look at it." He blinked in confusion.

"Dirty!"

"You should be proud of me...it...it shows that I'm healthy." The writer couldn't continue.

"Damn fat house!"

The writer shook his head, "I'm not."

The writer discovered a problem. When he was with this woman, he talked more.

Just when the two were about to fight, an intellectual young woman with round eyes and a long coat pushed the door open.

After looking at the deserted courtyard, he walked up to the writer and bowed respectfully, "You must be Mr. Jiang."

The writer nodded, "Are you Lin Ying?"

The young woman shook her head, "No, Professor Lin is my tutor. She is waiting for you upstairs."

"Well, thank you."

The writer switched to the tracked wheelchair and looked back at Kawa Yuan. Kawa Yuan snorted, "I won't disturb you to accompany your sister. I'm going to find my mentor."

Chuanyuan is also a graduate student at Jiangnan University, so naturally Mr. Jin’s workplace is also Jiangnan University.

"I won't send it."

The girl with glasses pursed her lips and smiled softly.

The writer glanced at her, "What are you laughing at?"

"Mr. Jiang, I heard that you are a weirdo, but I didn't expect that you don't look so weird," the girl with glasses helped the writer push the door open.

"Be careful if I sue you for libel."

The university physics laboratory is very simple, with a spiral staircase and a huge wooden school badge standing in the middle.

On the left is the teaching building and on the right is the laboratory.

However, the laboratory does not have any fancy machinery, but there should be a lot of slide weights.

Lin Ying's office is in a corner on the second floor. There are two pots of half-dead iron trees at the door.

The girl with glasses stopped at the door and knocked, "Teacher."

After a long time, a lazy voice came from inside, "Oh, come in."

However, the girl with glasses did not go in. Instead, she turned around and whispered in the writer's ear, "Teacher is in a bad mood recently, so be careful."

The door creaked open.

The writer pushed the wheelchair and walked slowly inside.

A strong aroma of wine wafted over. It was dark inside and the curtains were drawn.

The artificial light has no warmth at all, and the cold wind blows gently, probably from an air conditioner.

The room was very messy, with celestial models scattered all over the floor.

It seems that he has experienced something very intense, a whole Shura field.

The huge blackboard is densely written with mathematical formulas, and the screen is full of algebra. If you don't recognize it, you might think it's English.

The beginning is the inverse trigonometric function of Taylor expansion, arctan(1)=π/4

This is? Pi?

artan(x)=∫1/1x2*dx

After changing to the number 1, it becomes the Gregory-Leibniz formula. Of course, this algorithm is very irritable. Not only does the limit error be large, but it is also impossible for humans to calculate.

So I wrote half of it, followed by an accelerated convergence test, which is an auxiliary method used by the British mathematician Machin in the 18th century, π/4=4arctan1/5-arctan1/239

But it turns out that this method of calculating pi is also wrong. The problem lies in the 528th bit. In one sentence, the extreme value is not detailed enough.

So the back half was replaced by a small gray ball.

There are also some Ramanujan formulas later, which are used by some people in the massive calculations of the Constant Era.

Chunovsky's formula 1/π=12∑(∞,k=0)(-1)^k(6k)!(1359140954514014k)/(3k)!(k!)^3*640320^3k1.5

As for the later writers, I don’t understand. After all, the writers don’t understand mathematics. (The author doesn’t understand either)

There are probably some inferential pi calculation formulas, but most of them are old-fashioned and ancestral.

In fact, no matter which formula is used, the principle is very simple and it is a geometric algorithm, which is roughly equivalent to Zu Chongzhi's circle cutting technique. It just uses abstraction and then performs a bunch of fancy calculations.

"belch!"

A wine burp.

The writer just noticed that a young girl was sitting on a chair in front of the blackboard holding a wine glass.

He was wearing a white coat, his hair draped over his shoulders, and a pair of long legs resting on the podium, lying on the table in a daze, with his back to the writer.

"Um?!"

Turn back.

The golden sunlight from the curtains fell on a pink face, and the dark hair was lightly shiny.

Her cheeks are blushed, and her high bridge of nose divides the sunlight into two halves, with one side bright and the other dim.

Those eyes were scarlet with cobwebs, and it looked like she was in a very bad mental state.

"Hiccup!" Lin Ying burped again.

She drank a lot. In this case, either physics exploded or her boyfriend cheated on her.
