Xueba's Sea of ​​Stars

Chapter 10 A Fulfilling Life

"If you want to solve the problem of uniformly decelerated linear motion with zero final velocity..."

"Reverse thinking method."

"Okay, I've learned to answer quickly, right? Let's ask again... Forget it, forget it, I won't ask you."

After leaving Wu Bin in the office, Cai Guoping kept throwing out all kinds of high school physics questions, but they were all answered by the boy in front of him. Whether it was formula substitution or some error-prone questions, he answered very well. decisive.

Hearing that Cai Guoping finally stopped throwing questions, Wu Bin also heaved a sigh of relief. For half an hour, he felt as if he was participating in a program like "One Stop to the End". I can't ask him to throw some difficult questions, but I have been asking around the basics.

"How long have you been studying by yourself?" Cai Guoping asked Wu Bin as he walked to the water dispenser to pour himself water.

"Well...about a week."

At this moment, Wu Bin absolutely dare not say that he only learned such words by himself all afternoon, otherwise the teacher in front of him might jump his feet.

"Oh, I see you have been tossing about mathematics."

"I will watch it during my evening self-study. I am still very interested in physics."

Hearing this sentence, Cai Guoping finally showed a smile on his face, "It's a good thing to be interested, as the saying goes, interest is the best teacher."

"Teacher Cai said yes."

"Wait a minute, let me see if I have any papers for the first year of high school here." Wu Bin naturally passed the test, so Cai Guoping sat back at his desk and rummaged through the boxes when he opened the second drawer. , he searched and asked: "Did you read the electronic part?"

"Not yet, I just read the book in the first year of high school." Wu Bin shook his head. Electricity is the focus of the second year of high school, and he still has no concept in his mind.

"Then you can hurry up and look, electricity is more interesting than force."

"Okay, I'll watch it tonight."

Now Wu Bin's confidence in studying physics is completely overwhelmed, and he is confident that he can control thunder and lightning in just one night of self-study!
After a while, Cai Guoping took out two papers and said to Wu Bin: "I really don't have any papers on pure mechanics, so you can take this set and do it first, and I will help you find it tomorrow."

"Thank you, Teacher Cai."

Wu Bin took the test paper with both hands, and couldn't wait to spread it out and start working.

The multiple-choice questions at the beginning are relatively basic sub-questions, such as asking which of the following groups belongs to the basic units of the International System of Units, the correct statement about curved motion, etc., and then the next few questions that require calculations are not difficult, It can be solved easily.

These basic knowledge are completely engraved in Wu Bin's mind, and there is no reason for mistakes.

But the next big question made Wu Bin stuck.

Cai Guoping, who had been watching Wu Bin doing the questions, saw that he was stunned, and said, "Which formula should be used when it comes to the problem of time and the problem of descending displacement?"

"The displacement time formula." Wu Bin answered with certainty.

"Then what are you still thinking about?"

"I'm thinking about how to solve the second question..."

This sudden question about free fall instantly shattered the expansion that Wu Bin had just established. He originally thought that as long as he understood the formula thoroughly, he would not be afraid of any questions. There are only seventeen or eighteen bends, and they are all paper tigers!

But now he knows he was wrong, this turn is a five-peat hairpin turn!Too much test operation!
"Hey! That's right, I don't know how to do it." Cai Guoping smiled brightly when he saw Wu Bin deflated.

'Childish middle-aged people! '

After complaining silently in his heart, Wu Bin asked flatteringly, "Teacher, please teach me."

"Listen, when you see this kind of questions connected in series, it is best to use the whole method, and there is also the segment method. I will teach you later."

After speaking, Cai Guoping began to patiently explain the problem-solving method to Wu Bin.

"So now you know the average speed in the last second?"

"20m per second?"

"By the way, isn't it very simple?" Cai Guoping put down his pen and looked at Wu Bin.

"After listening to the teacher, I think it is very simple, the teacher is awesome!"

After solving this problem, Cai Guoping's image in Wu Bin's heart finally changed from a "unyielding and naive middle-aged old man with hair loss" to "a physics master with a halo!"

"This kind of question is not worth the word awesome. The difficult part is yet to come, so let's continue." Cai Guoping said that even though he said so, his brows were still a little complacent, and he understood why Liu Yushan gradually fell behind. Don't stop Wu Bin from praising him, this feeling of being admired by students is really flattering.

Then under the guidance of Cai Guoping, Wu Bin did all the questions he could do in the several sets of papers in the office, and he still had some ideas.

"Okay, it's almost time, let's go to the cafeteria." After teaching the last question, Cai Guoping looked at the clock on the wall and said.

"Okay, thank you Teacher Cai."

In fact, Wu Bin felt that he hadn't done it yet, but he was too embarrassed to waste the teacher's time, so he reluctantly said, "Teacher, can you give me some more papers?"

Cai Guoping was taken aback after hearing this, then laughed and said, "Hahaha, okay, I'll pick two for you."

Wu Bin, who finally got the paper, bowed and left the office happily, looking forward to having fun again during the evening self-study.

"Teacher Liu, it's really interesting to teach this kid."

When Wu Bin left, Cai Guoping looked at Liu Yushan and said while sorting out the textbooks.

"It's quite interesting." Liu Yushan chuckled, "I just can't figure out how a person who basically gave up studying in the past two years can become so motivated. It can be said that he is better than any student I have ever met... Tsk, how should I say it?"

"Eager to learn." Cai Guoping answered.

"Yes, that's the feeling. After all, the look in the eyes when you are doing the question can't lie."

"Hahaha, the look in your eyes won't lie if you ask me for the paper." Cai Guoping laughed again when he thought of Wu Bin's expression when he asked for the paper just now.

Liu Yushan also laughed after hearing this: "He reminded me of my little grandson's expression when he wanted to play more game consoles on weekends."

"That's right, that's how it feels." Cai Guoping strongly agreed, "How can this person change so much, tsk tsk, probably this is puberty."

Cai Guoping shook his head and sighed, then continued to sort out the textbooks.

After dinner in the cafeteria, Wu Bin immediately rushed back to the dormitory to find out the physics books for the second and third year of senior high school. Although it was not so easy for him to solve the convoluted exam questions, he managed to get rid of these two books in one night of self-study. It should be no problem to absorb the basic knowledge in it.

As expected, the ending was not as Wu Bin expected. In just two self-study classes, he finished reading the physics of the second year of high school, but when he was about to open the physics book of the third year of high school, he suddenly remembered that today's three-hour system tutoring had not yet finished. It is useful, so with the thought of not daring to waste, I immediately took out the math book and started studying.

"Ah, life is really fulfilling."

Wu Bin, who was holding a math book, couldn't help feeling emotional.

"nausea!"

Gu Fan, the underachiever next door, couldn't help complaining.
