With Xiao Nannan, Yang Chen returned to the quiet room.

But before, he called Liu Lei and asked him to come over.

"Brother Yang, what's wrong? I'm still busy. My experiment with the aura attribute is at a critical moment......" Yang Chen seemed to see Liu Lei's little face on the other end of the phone, and he looked very reluctant.

"I really don't want to come, I have a very talented child here, and his research value is very high. ”

"The talent is very high, how high is it?" Liu Lei is a genius himself, and he is not very interested in geniuses.

"Very high, very high, her energy particle affinity is at least a hundred times higher than that of normal people! And she also has a super talent for mathematics, she can do large number operations within at least a hundred digits, including addition, subtraction, multiplication, division, square, multiplication, etc., and can get the correct answer in one second!" Yang Chen tempted.

Liu Lei was immediately overjoyed: "What? There is such a thing? I'll come over right away!"

After only hearing a few knocks, he didn't even have time to hang up the phone, so he hurried over, and the knock sound was that he was too anxious and hit the door and the wall.

Yang Chen shook his head with a wry smile and hung up the phone helplessly. After thinking about it, he called Bai Yu again.

But there was no one on the other side. It's been like this for a long time.

Yang Chen then remembered that Bai Yu was also a research maniac, and it was estimated that the mobile phone had already been thrown aside by him because it was annoying, right?

There was no way, Yang Chen had no choice but to call Zhu Yingying and ask the old general to call Bai Yu over.

It's a pity that as soon as a person like Bai Yu falls into research, no one can wake up, even if Zhu Yingying is a general, it is no exception, after waiting for a long time, the old general pulled Bai Yu out with difficulty, handed him his mobile phone, and said that Yang Chen wanted to talk to him.

At this time, Liu Lei had already arrived, and he couldn't wait to study Xiao Nannan. Of course, Yang Chen wouldn't let him do this, Bai Yu hadn't arrived yet, making him like an ant on a hot pot, so anxious.

Fortunately, the little girl was innocent and cute, and she was very sensible, and talking to him next to her finally made him a little less impatient.

Bai Yu took the phone, not caring at all about Yang Chen's identity as a seventh-order real person, and said unhappily: "Yang Zhenren, what's the matter? So anxious? I'm studying at a critical moment now! Let you make such a mistake, and you have to start again, I don't know how much time you will waste......

Seeing that Bai Yu didn't give Yang Chen face like this, the quick-eyed little girl couldn't help but cover her mouth and snicker. Because he has a little aura in his body and has also enhanced his hearing, Liu Lei's eyes are shining, which means that heroes see the same thing.

Yang Chen smiled bitterly and didn't explain, and said helplessly: "Are you coming?" If you don't come, don't regret it later!"

"How interesting is it?"

"It's so interesting enough to make you regret it!"

"What? So what are you waiting for? I'll be right there. ”

Without waiting for Yang Chen to speak, Bai Yu had already hung up the phone.

It didn't take long for Bai Yu to rush into the quiet room.

As soon as he entered the quiet room, he was surprised to take out an instrument with a colored LCD panel from his arms, swept the front end around, and said strangely: "Huh, my energy particle detector obviously detected strange fluctuations with energy particles, why did I investigate carefully, but I didn't find anything?"

As he spoke, he fiddled with the instrument, "clicked" to open the back panel of the instrument, and I don't know where he pressed, the interface of the energy particle detector immediately changed, and it became an interface full of dense program code.

Then Bai Yu kept modifying the parameters on this interface.

Liu Lei's eyes were hot, and he hurriedly leaned over and asked, "What kind of instrument is this? Why haven't I seen it?"

Bai Yu continued to concentrate on modifying various parameters, and replied without looking back: "Of course you haven't seen it, this is the energy particle detector I specially invented to detect energy particles, codenamed 'Lingying'." ”

Liu Lei's eyes lit up: "You did it yourself?"

"Of course. I didn't do it myself, who did I buy it? Energy particle detection technology, but I am the only one who has mastered it!"

"You still have mastered this technique, can you teach me?" Liu Lei is particularly interested in new knowledge.

Bai Yu didn't have much patience: "I don't have time, learn it slowly!"

As he spoke, he glanced at Liu Lei, who was five or six years younger than him, and his face softened slightly: "I see that you still know how to be motivated, well, in this way, I will write this formula to you, you can deduce it yourself, don't bother me if you can't deduce it." ”

After speaking, he grabbed a blank piece of paper and a ballpoint pen, wrote down a line of formulas on the paper, and then buried himself in the research again.

Liu Lei took the blank paper, frowned and looked at it carefully, falling into deep thought.

For a while, the quiet room, which was originally noisy, fell into silence again.

Chen Ang, who was sensing energy particles with his eyes closed, was still a little accustomed to the noise around him, but he suddenly calmed down, but he was a little unaccustomed to it, opened his eyes and looked around, and then continued to re-enter the induction.

Of course, his efforts for so long still had no effect, and he was already a little impatient.

However, he is also an accomplished scientific researcher, and he still has patience. He took a few deep breaths and continued to enter the induction.

Yang Chen was idle and bored here, so he began to teach Xiao Nan Shang Jingyi some more in-depth mathematical knowledge, such as trigonometry, calculus, and the like.

He is not in a hurry to enlighten Xiao Nannan now, but plans to wait until Bai Yu and Liu Lei are busy and can conduct in-depth research throughout the process. Xiao Nannan is so talented, it is naturally a rare sample, how can it be easily missed?

However, after teaching Xiao Nannan for a period of time, although he already knew that Xiao Nannan's talent was extraordinary, Yang Chen was still shocked.

Because no matter how profound the mathematical knowledge, Xiao Nannan can quickly comprehend it. Especially those difficult and obscure derivation formula transformations, even if Yang Chen had to rack his brains, Xiao Nannan came up with the correct derivation process in a blink of an eye.

This made Yang Chen have to sigh, a kind of mathematical talent like Xiao Nannan, who can instantly get calculation results in his mind and is intuitive, is really envious, jealous and hateful.

This also made Yang Chen more and more happy. Such a talent is really rebellious.

Chen Ang, who was sensing energy particles over there, was still inducing, but hearing Yang Chen constantly telling Xiao Nannan about the mathematical formulas also made him unable to calm down anymore.

Although he is engaged in new energy, mathematical tools are indispensable in the experiment and research of new energy. I know a lot of things taught by Yang Chen, not to mention it, I am familiar with it.

The more I listened, the more I was shocked.

Because he found the same mathematical knowledge, Yang Chen barely told it a second time.

"Could it be that the little girl only spoke once and understood? This is impossible!" Chen Ang almost doubted life, and finally he couldn't help but open his eyes, get off the sofa, and come to Yang Chen's side to see if Xiao Nan Nan could really understand this mathematical knowledge so quickly.

Then all he had left was to grow his mouth and widen his eyes.

"Monster! It's a monster!" Chen Ang asked himself, he is also a person with good talent, otherwise, he would not have the ability to invent a new solar photovoltaic cell film. But he found that his talent, which he had also made him proud of, and who was among his classmates and friends in the name of a scholar, was simply scum in front of this cute little girl.

"From now on, I will never dare to say that I am good at math. Chen Ang said to Yang Chen with a wry smile.

Yang Chen shrugged his shoulders sympathetically.

Isn't it? Xiao Nannan's talent is simply a natural scientist seedling. But she also has a strong cultivation talent, and she is simply born to become a hero who will save mankind in the future.

It's a pity that Yang Chen has never heard of Xiao Nannan's name in later generations, and he must be the same as Bai Yu Liu Lei, for various reasons, he was not able to grow up and was buried in the vast sea of people.

To say that the subject of mathematics is of course broad and profound, but the most cumbersome is the derivation and summary of those formulas, and the reason why people cannot understand those esoteric mathematical knowledge is also because of the difficulty of derivation. After all, the vast majority of knowledge in mathematics is derived through various deductions. As long as this problem is solved, it will not be difficult at all. At the very least, there is no difficulty in learning what you already know.

Moreover, those really cutting-edge mathematical knowledge are still purely theoretical, and those that can be used in real daily scientific research are still those mathematical knowledge from many years ago.

For example, the mathematical tool used in general relativity is Riemannian geometry. Riemannian geometry was founded in the mid-19th century by the German mathematician G. G. F。 B。 Riemann was founded. The general theory of relativity was proposed by Albert Einstein in 1915, with an age difference of about sixty or seventy years.

The mathematical tools used in the theory of energy particles are similar in difficulty to Riemannian geometry. And this is only needed after a very deep study. If it is only a relatively superficial study, it will be much less difficult.

In short, the mathematical tools commonly used in the theory of energy particles were quickly explained by Yang Chen to Xiao Nannan. Of course, the specific theories and formulas are as vast as a sea of smoke, and they can't be explained in a day or two, but if you want to learn them, you will be very fast.

Even, now Xiao Nannan has shown her ability. When Yang Chen finished speaking, Xiao Nannan curiously came to Liu Lei's side, looked at the formula that Liu Lei was frantically deriving, and suddenly stretched out his little hand, pointed to one of Liu Lei's derivation steps, and said crisply: "Brother Liu Lei, there is a problem with this step, something is wrong." ”

"What?" Liu Lei looked up from the manuscript paper blankly and looked at it carefully: "I didn't miscalculate." ”

"Wrong, it's really ......" Xiao Nan said seriously with big black eyes.
