Into Unscientific

"Student, excuse me, what triangle did you just say?"

Hearing these words, the two girls, who were a little surprised by the falling of the book, were taken aback for a moment, and immediately raised their heads to look at Xu Yun.

The tall girl gave him a strange look and said:

"It's the Yang Hui Triangle, what's wrong, classmate?"

Another girl named Yueyue had to be more careful, and her eyes stayed on the card that Xu Yun was holding in her hand for a while. This boy is a master's student or a doctoral student, but alumni of this degree should theoretically not know the Yang Hui triangle.

So subconsciously, the girl felt that the boy in front of her was probably looking for a reason to strike up a conversation.

This kind of situation is quite common in libraries. Some shy ones will pass small notes or use answering questions as an excuse to get closer, while others will take the initiative to strike up a conversation and ask for WeChat.

There are also some fierce people with good grades who are awesome. Most of these people are graduate students. They will secretly write down the books the other party has read, and after determining the target grade, apply to be a teaching assistant or something.

Xu Yun knew such a talented person. In the first year of his doctorate, he published two papers in the second district, but in the end he went to the freshman as a teaching assistant in order to catch up with the school girl.

However, it is very tragic that on the first day of becoming a teaching assistant, the first foot stepped into the classroom when he found the junior girl looking at him with a smile on her face—note, sitting on her boyfriend's lap.

what a sad story

However, because the University of Science and Technology has always been rigorous in its research, neither boys nor girls have made any radical moves, which can be regarded as a normal initiation of puberty.

Unless you are really being harassed a lot, you will contact a teaching assistant or counselor to intervene.

Therefore, the girl named Yueyue just tugged on her companion's clothes lightly, signaling not to communicate too much. There is probably something wrong with science students who can use Yang Hui's triangle as an excuse.

But Xu Yun didn't care about these, his thoughts were all attracted by what the other party said:

"You mean it's also called the Yang Hui Triangle internationally?"

"yes."

"And what about Pascal?"

Hearing the word Pascal, the tall girl couldn't help frowning slightly—it's impossible for someone who can say the word Pascal not to know the Yang Hui Triangle?

However, out of basic respect for alumni, she patiently explained:

"Pascal's Triangle is Yang Hui's Triangle, but he announced it much later than Yang Hui's Triangle, so now the name Yang Hui's Triangle is used internationally."

The girl's voice was very soft, her eyebrows were thin and long, and she moved when she spoke, like willow leaves swaying in the wind in summer.

But Xu Yun's attention was only focused on what she said from the beginning to the end, and the more he listened, his eyes widened.

After a few seconds, he came back to his senses and hurriedly said thank you to the two girls.

Then turn around and leave.

The two girls looked at Xu Yun running faster than the Western reporters, and looked at each other inexplicably:

"?"

After a while, the short girl said with a strange expression:

"Ning Ning, it has been rumored that the University of Science and Technology has many strange people since ancient times. Is this the first time we have seen each other?"

The tall girl shrugged, and held her companion's hand again:

"Ah, ah, ah, let's find a book, the library will be closed if it's later."

Two flowers bloom, each representing a branch.

While the two girls continued to look for the books they needed, Xu Yun quickly came to a quiet desk, took out his mobile phone, and quickly typed in the words 'Yang Hui Triangle'.

Soon, the web page displayed the encyclopedia entry:

"Yang Hui's triangle is a geometric arrangement of binomial coefficients in a triangle. It appeared in the book "Detailed Nine Chapters Algorithm" written by Yang Hui, a mathematician of the Southern Song Dynasty in 1261. It was introduced to Europe by silk merchants in the middle of the 17th century. , and was accidentally discovered and researched by Newton in the Cambridge History Museum in 1665, and a number of mathematical achievements were deduced from this.”

"Pascal also discovered this law in 1654, but his discovery was officially released in 1666 after his death, and the Gallic Academy of Sciences published related papers. In his only autobiography, Newton clearly mentioned It shows that the Yanghui triangle appeared earlier than Pascal's triangle, and after he became the president of the Royal Society of Great Britain, he awarded Yanghui's triangle the official and unique name."

"At the Geneva International Mathematical Congress held in 1992, this geometric arrangement was officially named Yang Hui's triangle. This is also the only internationally recognized high-level theorem in China that belongs to a local name."

"Up to now, only a few mathematicians of the ancient school in Gaul have always insisted on calling it Pascal's triangle, and Yang Hui's triangle is used as the official name in international conferences and paper reports."

Then Xu Yun searched for the key words "Yang Hui Triangle#Silk Merchant" and found that there was no detailed mention of this person, and they only used the four words "Silk Merchant" to bring goods.

Looking at the search results displayed on the mobile phone in front of him, Xu Yun's shoulders suddenly relaxed, and he let out a complicated breath.

According to the results shown in the search results, the appearance of Yang Hui's triangle did not have much impact on the inherent theorems or results. It just replaced the original role of Pascal's triangle in the history of European mathematics.

Just like 1+2=3 changed to 1+two=3, it is a simple substitution effect and cannot affect the result.

In addition, the traces of Xu Yun's existence were also erased, replaced by a mysterious silk merchant from the East, and the location where the Yang Hui Triangle was discovered was changed from Woolsthorpe to the University History Museum of Cambridge University.

Li Feiyu was not seen, Han Li was not heard of, and no one mentioned Fenglingyue Shadow Sect.

Everything is so natural, and history has no deviation, but the name of this theorem has been replaced by Yang Hui's triangle.

A recognized Chinese name that does not need to be shared with others.

It is clear.

Compared with the pair of sneakers in Newton's portrait before, Yang Hui's triangle is the real reward egg!

Originally, Xu Yun's idea was just to hope that the light of wisdom of the Chinese sages would no longer be dusty in the timeline of the 1665 copy, but who would have thought that his actions would affect the present world?

Even though Xu Yun's 'achievements' were unknown, he didn't feel any pity at all.

This should be the glory due to the sages, he just did a little work.

Xu Yun sat quietly like this for a long time, and his eyes became firmer as he thought about it.

He doesn't know if he still has the chance to change the past, and he doesn't know if he can still get the Easter egg reward by such a coincidence, but he knows one thing very well:

That's where he has the opportunity to push the gears of the future now.

Although the mission system seems a little outrageous, there is no doubt about its ability.

Traveling through time and space and changing history is no longer something that the so-called cutting-edge technology can do.

The rewards for a so-called novice mission are so attractive, let alone formal missions, or difficult missions that may arise.

certainly.

To realize the rewards for completing the task, Xu Yun still needs his own efforts. Without enough knowledge reserves, no amount of rewards, no matter how good they are, are like two-dimensional paper figures, invisible and intangible.

Then Xu Yun took a deep breath, calmed down, and stood up again.

Although the prospect of the mysterious halo is very promising, his top priority right now is not to YY those unrealistic futures, but to do his own thing well, that is.

Deduce the receptor binding formula of sodium ion channel.
