Chapter 193 (1/2)
When Li Zheng was addicted to solving problems.
He did not know that Jiang Qinghua had been crazy for a long time.
The sun? Nuclear fusion? Nuclear reaction equation?
Jiang Qinghua, chaos.
The more chaotic, the more confused they will be.
The more chaotic, the more difficult it is to find simple and pure solutions.
I do not know how long after chaos, Jiang Qinghua aimed at the second question.
This is a classic problem about how to calculate kinetic energy and velocity when a small ball hits a pole.
This is good. It has a routine.
The formula of conservation of kinetic energy and momentum is right.
However, he was wrong.
He didn't know, in the physics contest.
The more terrifying it seems, the simpler it is.
The more mentally retarded things like balls and poles are, the more difficult it is.
For example, satellite orbit, solar nuclear reaction and other things, although the topic is very broad, but it is only a test of your application ability. As long as the physical environment and simple knowledge are linked together, the answer can always be easily given.
On the contrary, the ball and the club are so delicate that they can be used to assess you to the extent of horror -
Where did the ball hit the club?
What kind of torsion does the rod produce?
How do you rock back when you twist to the limit?
What is the final state?
By the way, two ends of the pole are also tied with a small ball.
In this complex situation, it is a foregone conclusion that calculus should be analyzed step by step.
In this process, Jiang Qinghua is undoubtedly getting deeper and deeper.
He began to doubt himself deeply.
Why study so long, on the contrary even small ball thin rod this kind of mentally retarded problem can't understand?
In the pain, Jiang Qinghua's stomach also does not compete to grunt, some can not carry.
In fact, this problem is really difficult, Li Zheng for a long time, far longer than the sun's nuclear fusion.
Just because of the calculation steps, it is too complicated and much more difficult than the math exam.
As for Lin Qijing
She used a strange method of angular velocity and angular momentum to solve the problem, completely bypassing the process analysis and derivative calculation, and had already started to do the third problem.
These three situations also fully reflect the style of the three people.
Li Zheng: a → B → C → C Lin Qijing: a → (strange idea) → Z
JIANG Qinghua: a →? →B→？ →A？ →C？ →…… →？？？
……
The war in the office is hot, but outside the office it is very leisurely.
On the way back from the water, Tao Feifei happened to meet Yu Hong, who came back from an interview.
Although there are not too many intersections on weekdays, in the face of the competition and how to cultivate Li Zheng and Lin yuejing, Yu Hong became enthusiastic for the first time and held Tao Feifei away.
”Xiao Tao, don't underestimate Li Zheng.”
”This man's progress is terrible.”
”And he is all-round, no progress in the dead corner of knowledge.”
”In the end, Shi Yang, who won Li Zheng a few points, was a chemical genius who had been immersed in the chemical laboratory since childhood and was once in many years.”
”As a result, Li Zheng's theoretical score is still higher than him? If it wasn't for the limited opportunities for experiments, it would be hard to say
”You just listen to me and give Li Zhengshu a highest goal. It's right to rush forward.”
Tao Feifei nodded again and again, but he didn't think so.
In her eyes, the gap between chemistry competition and physics competition is about the same as that between Asian Games and Olympic Games.
The core of the gap is that chemistry has a lot of hard to eat knowledge points, while physics is more talented.
This leads to those real demons who have no energy and no interest in chemical competition. Only physical competition can provide them with a stage to display their talents.
The core reason why Li Zhenghua got such terrible results was his terrible study intensity.
When it comes to the gift of thinking, he is certainly not bad.
Just, he will face, but a large group of forest more than static level of evil ah.
Of course, Tao Feifei is not good at facing Yu Honggang. At most, he only dares to be evil.
”Mr. Yu, let me ask for some advice.” Tao Feifei rubbed the kettle and asked, ”you see, Li Zheng and Lin yuejing were second and seventh in the preliminary competition of Huajing, which was about 5 points short of each other, right?”
”Yes, I didn't expect Li Zheng to be higher.” Yu Hong repeatedly nodded, ”you know, at that time, Shi Yang was five points higher than Li Zheng, and after only a month's effort, Li Zheng's national decision results completed a comprehensive anti super.”
”Yes, yes But I want to ask... ” Tao Feifei pursed his lips and said, ”take the preliminary competition of Huajing as the time node. If Li Zheng's energy in learning into competition is 100, how much is Lin yuejing
“……” Yu Hung eyebrow color tight, thought for a long time, then raised his hand, compared a 2.“20？” Asked Sophie.
“2。”
“……”
“……”
The two men fell into a long silence.
”In fact, this 2, I have said more conservative I feel she's more attentive in playing basketball. ” Yu Hong shook his head and sighed, ”no way, I have never seen Lin Passover Jing in this degree in my life.”
”If you say that, I have a higher expectation of Lin yuejing...” ”You know, Lin yuejing's investment in the face of the physical competition,” Tao Feifei said, taking a cool breath It's 100. ”
”My mother...” Yu Hong was surprised and opened up. ”Then you Can you teach me? ”
”Ah!” ”It's too hard. She has problems occasionally I can't understand what I'm asking I suspect that my graduate student is false... ””
”Fortunately, she didn't ask me a chemistry question.” Yu Hong took the rest of his life and turned his mouth to the office. ”What are they doing now?”
”To do the re match is equivalent to your preliminary race.” ”They are more aggressive,” taufifei whispered
”Normal, chemistry is also occasionally fighting.” Yu Hong didn't feel like he was looking forward to it. ”Is that the real problem? Do you know the score line? ”
”The truth, I know it all.” ”But I can probably guess the result,” said tauffield, shaking his head
”Ha ha.” Yu Hong squints his eyes and pattes Tao Feifei gently. ”You are still too young.”
“……”
”I'll talk to you when it turns out.”
”Miss Yu, the problem has to be more than 7 p.m.”
”It's OK. I'll wait for you.” Yu Hong also took out his cell phone and swallowed his mouth. ”I haven't eaten barbecue for a long time.”
“……” Tao realized that Yu Hong was going to eat something terrible at school again.
Yu Hong at this time, has played with the mobile phone far away: ”then I ordered a six person, good or bad there are two big and small boys.”
”You It's a waste... ”
……
Tao Fei entered the office, and saw three people trying to solve the problem, which meant that he didn't want to peep.
But it was still unbearable.
As a physics teacher, she is very confident in her judgment.
This confidence is not natural, but is honed out in the comparison of prediction and results.
Li Zheng 35, jiangqinghua 14, Lin Yue Jing 75.
That's what she predicted, the best level of three people to play.
It's been more than 20 minutes now, and some clues can be seen.
Tao Fei then quietly slipped to Lin Passover Jing behind.
Rarely, Lin yuejing did not find her peeping, still bow to carefully check the calculation.
Tao Fei scanned the answer paper, and saw the beautiful answers to the first three questions, only nodding steadily.
It is not worth Lin yuejing. Maybe the fifth question will feel difficult.
Then, Tao Feifei then slipped to jiangqinghua.
Looking at his white answer paper, and scattered grass manuscript.
Taufeifei laughed and said nothing.
It is really too grudging to get back to the game.
Finally, I look at Lizheng.
At one glance, tauffield got flustered.
The draft paper is almost full
Even the answer paper also wrote a lot.
But only the first two questions give a complete answer, the latter questions are only a few trivial steps, far from the answer.
What kind of routine is this, dirty problem?
Dirty points, that is, clearly will not do, but can write a lot of specious things, which point hit, can get a point or two.
Tauffield couldn't help carrying his glasses and looking carefully.
She found that Li Zheng was not a hard writing knowledge point, and that step 8 Chengdu, as shown on the answer paper, was OK.
But he had no idea but he didn't know how to calculate it.
Even so, tauffield was very satisfied.
Li Zheng is much more flexible than she thought, and his ideas are very broad. Now he is only poor in skills. Training, and saving a lot of opportunities.
With such a comfortable mood, Tao Feifei sat back in front of the computer, planning what homework to keep today.
She did not know that Li Zheng had been in a desperate situation.
At first glance, Li Zheng seems to sweep the problem very quickly, and he has been out so much in 20 minutes.
In fact, Li Zheng has been driving for a full minute to accelerate, equivalent to crazy for two hours of the problem.
These trivial steps on the answer paper are almost everything he can answer.
Li Zheng has already estimated his score. This volume has the maximum score, which is more than 30.
Facing this result, Li Zheng only bowed his head and sighed.
It is not worthy of Mr. Tao. This estimate is really accurateHe could have continued to accelerate.
But that doesn't make any sense.
Just can't do it.
The reason is nothing but mathematics.
In fact, 70% of the questions on the volume, Li Zheng have solutions.
But if we do it, we will soon be stuck in the throat by mathematical calculation.
Some people say that in terms of the amount of thinking, mathematical competition is six times that of physics.
