Xueba's Sea of ​​Stars

Chapter 22 Knowledge Talent Tree

'MMP... what is this, what, what! ! ! '

After getting the three thick books from Cai Guoping and leaving the office, Wu Bin was so excited that he skipped dinner and went back to the classroom to start reading. But after an hour, he found that his IQ was not enough.

The three major conservations, the two major laws, the constraint equations, and so on, were almost all overthrown what he thought he understood, and the whole thing entered a new world.

And he discovered a problem in "The Mechanics of the Middle School Olympic Physics Course", that is, the end of physics is completely a sea of ​​stars!Various astronomers interspersed among them.

For example, people used trigonometry to measure the distance between the earth and other stars at the beginning, that is, the revolution of the earth around the sun provided a baseline for measuring the distance of stars outside the solar system.

Then use the telescope to point at the star to be measured in winter and summer, and accurately measure two angles, so as to calculate the distance between the earth and the star.

But then a new problem appeared, the star to be measured is too far away from the earth, what should I do if I can't use trigonometry?
At this time, astronomers stepped forward.

They found that the intrinsic brightness of a star can be estimated from its color.

So by using the trigonometry to measure the color and internal brightness of many stars close to the earth, a definite relationship was established, and finally the more distant stars were measured with the help of this relationship.

"Scientists are indeed monsters..."

But what makes Wu Bin full of MMP is not these three thick books, but what Cai Guoping said is the second of the two things he needs to do now.

Two textbooks, "Newly Edited High School Physics Olympiad Guide" and "Newly Edited High School Physics Olympiad Use Question Dictionary"

Since the covers of the two books were one black and one white, Cai Guoping said that when he gave it to him, he had made the two "black and white covers."

But now Wu Bin wants to call them black and white double evil, because they all want their lives!
When reading "The Mechanics of the Middle School Olympic Physics Curriculum", Wu Bin was actually not too slow to understand. Although he can't say that he can understand it like a high school physics book, he can at least understand it and find it very interesting.

But when he opened the "New High School Physics Olympiad Use Questions", he was about to explode after doing two questions.

How should I describe his mood? It's probably like this style of painting.

When reading the book, the book taught him that, suppose you have a rabbit, and then someone gave you another rabbit.

So how many rabbits do you have now?

Yes, two, really smart.

So, 1+1=2
This is how arithmetic works.

So now that you have a certain understanding of the basic principles of arithmetic, let's take a look at the following example to put what we just learned into practice.

Example 1
计算lim（n分之1+（n+1）分之1+n+n+（2n）分之1）

解：因为（2n）分之n+1小于n分之1+（n+1）分之1+n+（2n）分之1小于n分之n+1
且lim（2n）分之n+1=0，limn分之n+1=0
由迫敛性定理知：lim（n分之1+（n+1）分之1+n+（2n）分之1）=0
'I will untie your horse! ! ! '

The painting style of difficult questions has changed, okay?

At first, Wu Bin thought that he had learned a few new formulas, which might solve two problems, but after studying for a long time, he found the first so-called basis!foundation!question!It's a super complex comprehensive question, and the super outline is so super two-dimensional!

The final conclusion is that when Wu Bin read "The Mechanics of the Middle School Olympic Physics Course", he used his brain, analyzed and analyzed logic, and did sample problems, and he felt a feeling of "Mom, I have learned physics".

Close the book and do the questions.

"What's Ma Mei here?"

Then I opened the book and read it seriously, deeply remembering in my mind, Ma Dongmei, Ma Dongmei, Ma Dongmei!

When continuing to the next question.

Sun Honglei? ? ?
And Wu Bin took a rough look at the following questions, and found that there are 100 painting styles in the 90 questions, and the remaining ten questions are all abstract!

"This is too exciting..."

Wu Bin wiped the sweat off his head and said with emotion.

'Old iron, open the lowest-level tutoring tutorial and help me out. '

At this moment, Wu Bin, who still prefers to rely on himself most of the time, also conceded, and immediately sent a distress signal to the system.

"The lowest-level tutoring tutorial has been started, and the remaining time is 2 hours, 59 minutes and 59 seconds."

'Old iron, how to do this question? '

Wu Bin pointed to a circular motion question in the "New Textbook of High School Physics Olympiad Questions".

"Hey, it has been detected that the host has begun to contact low-level knowledge and is analyzing the knowledge content, please wait a moment."

???

'Am I jumping out of the lowest level? '

But this scalp-numbing question is just low-level knowledge? ? ?Oh, that's right, after all, a ninth prize has transformed my physical ability.

"Analysis complete"

"Confirm that the ability of the host has been slightly improved, and the energy provided is sufficient."

"Alternative 9 successfully opened"

"Converting to the expression the host can best understand."

"Successfully converted"

"Knowledge talent tree opened"

This is... an upgrade?

Wu Bin scratched his head and asked in his head.

'Old man?What is this talent tree'

What is strange is that this time the system did not answer him as usual "Sorry, this question is not within the scope of inquiry."

Instead, a picture was displayed in Wu Bin's mind, with a large number of dark grids drawn on it. On the top of these grids, there were subjects such as Chinese, physics, mathematics, and English.

At this moment, Wu Bin immediately understood, this is a bit of talent!

Wu Bin, who understood the meaning, first selected the physics tree, and learned about several talent effects that can be clicked on the first line.

[Gravity: increase the understanding of mechanics and improve the ability to use various laws of mechanics]

【Controlling Lightning: Increase your understanding of electricity and improve your ability to use various laws of electricity】

[Scientific image: stabilize the hairline, and have a head of black and thick hair while learning physics well]

???

What the hell is the third talent? ? ?And the most coquettish thing is that it has been lit up!
'Old iron!I don't have the talent to focus on scientific images! '

"Because the host's physical ability accounted for most of the contribution value during the activation of Alternate Plan 9, this is a special gifted ability that does not consume talent points."

'Oh, I'm relieved then. '

Come to think of it, this third talent is actually very practical!

Look at Teacher Cai, look at Teacher Wu!Which is not the crazy movement of the hairline back.

Thinking about it again, when Wu Bin first entered school, he also heard the cry from the soul of several high school science students.

"I still have a lot of hair, I can still study chemistry (physics)!"

In fact, when Wu Bin washed his hair recently, he did find that his hair seemed to be falling out a lot more than before, but because of his good looks, he didn't care much.

Thinking about it now, I was afraid for a while, and imagined his appearance in the Mediterranean, Wu Bin felt his heart tremble!

'Old iron, don't say anything, it's too good! '

Wu Bin sincerely praised the system.
