Chapter 39 Asking Academicians
In the living room, Li Na, holding a little guy with a milky smell, fell into deep thought.
I woke up early this morning and walked here specifically from the community. It was obviously to "care" for Mo Jingchun, so that Mo Jingchun would return home knowing he was lost. He would listen carefully to the class and concentrate on learning professional knowledge. .
But...why the result was different from what was expected? Instead, he pushed Mo Jingchun, making Mo Jingchun go further and further on the road to "blackening".
The more she thought about it, the more Li Na felt that something was wrong, and her mind couldn't turn around for a while.
Looking at the two doors opening opposite each other, Li Na couldn't help but think that it was too late to say anything now. The guy had already run over to ask Academician Chen Xihe for advice.
"Forget it, everyone has their own way to go." Li Na sighed and shook her head.
Looking at the milky candy in her arms, Li Na's mood instantly improved. Li Na found that she now likes children more and more.
No, I must tell my mother next time I go back and ask my brother and sister-in-law to have a cute baby as soon as possible.
Hmph!
We have been married for more than a year and still want to live happily for a few years. How can this be done?
Li Na raised her eyebrows and decided that from now on she would go to her brother's company every now and then to urge the two guys.
On the other side, Mo Jingchun followed academician Chen Xihe obediently with the notes on the recorded questions.
Chen Xihe picked up the glasses case on the table, opened it and took out the reading glasses inside. He said with a smile on his face: "Come, show me the problem you encountered. It’s good to love learning. It’s because there are many people like you who love learning that the country becomes stronger and more prosperous.”
Mo Jingchun touched his nose in embarrassment. , I don’t know how to answer what Academician Chen Xihe said.
If he was really as good as Academician Chen Xihe said, Mo Jingchun felt that he could wake up with a smile even when he was sleeping.
Chen Xihe sat on the sofa wearing reading glasses and opened Mo Jingchun's notebook.
The word "good" caught his eye, and Chen Xihe couldn't help but twitch the corner of his mouth.
Excellent in learning and loving learning, why can’t I write well?
Fortunately, although the writing on the notebook is not pretty, the handwriting is quite clear and I can still recognize every word.
"Mo Jingchun, I'll call you Xiaochun."
"Tsk! You need to practice more when your handwriting is fine. You can't just absorb new knowledge all the time. Good calligraphy is also very important. In the words of you young people, good handwriting means good pretense at critical moments. " Question after question, even those that Mo Jingchun had crossed out with his pen, were not missed.
Besides, Mo Jingchun stretched out his head and said: "Teacher, the ones I crossed out are the problems I have solved by searching the information, and the rest can't be found in the book. ”
"Yeah." Chen Xihe just hummed slightly, and then continued to read the various questions recorded by Mo Jingchun page by page.
About ten minutes later, after reading all the questions in Mo Jingchun's notebook, Chen Xihe turned the notebook back to the first page.
Then, Chen Xihe raised his head and looked at Mo Jingchun. As soon as he spoke, Mo Jingchun was shocked.
“Are you studying something similar to a stabilizer or a balancing device?”
Looking at the shock in Mo Jingchun’s eyes and the look of disbelief on his face, Chen Xihe A smile appeared on his face. Now, Chen Xihe was very sure that Mo Jingchun was studying something similar to a stabilizer or balancing device.
Just as Academician Chen Xihe thought, Mo Jingchun was indeed surprised by Academician Chen Xihe, and it was nothing more than a prophecy.
Mo Jingchun thought, is this an academician? Just based on the unanswered questions and doubts he recorded in his notebook, he can know the surface from the lines and the body from the surface! and then infer the type of product being studied.
Smart anti-shake spoon, to put it nicely, is called smart anti-shake spoon, but to be more realistic, in the final analysis, the smart anti-shake spoon is still a balancing device.
Mo Jingchun nodded with dull eyes, swallowed his saliva and replied: "Yes, teacher, I am developing an intelligent anti-shake spoon. I am very confident in myself about the software algorithm, and It has been developed now, but as you can see, it faces various problems."
"Smart anti-shake spoon?" Chen Xihe nodded. "It's a good thing."
As an academician and an old man, there is never a shortage of old guys around me whose hands start to tremble involuntarily as they get older.
Especially for some old guys who have suffered a stroke, they can no longer eat by themselves and rely on others to take care of them.
Thinking of the little guy Mo Jingchun confidently saying that there was no problem with the software, Chen Xihe smiled and was not prepared to dampen the little guy's enthusiasm.
The hardware is not ready yet, but the software is. That is impossible. For any mature electronic product, the software and hardware must undergo final adaptation before they can be adjusted. Best condition.
Although computers in this era have powerful computing capabilities, the results of simulations are only the results of ideal models. In the actual process, unimaginable problems will always be encountered that have never been thought of.
Chen Xihe pointed to a question on his notebook and said to Mo Jingchun: "Here I suggest you use screw transmission instead of gear transmission."
"Why?" Mo Jingchun scratched his head He asked in confusion.
"Good question! Why?"
"Have you ever thought about it, although gear transmission has many advantages, its transmission is more accurate, efficient, compact, reliable, long life Long, but also, if your smart anti-shake spoon uses gear transmission inside, have you ever thought about how many large and small gears are needed inside the smart anti-shake spoon to complete the complex movement of anti-shake? ”
"Do you know about mechanical watches?"
Mo Jingchun nodded.
“I know.”
Chen Xihe looked at Mo Jingchun and asked with a smile: “What was your first impression of the mechanical watch?”
Mo Jingchun thought for a while and said: "Expensive."
"Yes, it is expensive. The more accurate the time of a mechanical watch, the more precise the internal gears, which means the cost will increase. ”
"As a daily necessities, the smart anti-shake spoon is not a luxury product. If the price is too expensive, few people will be willing to take advantage of it."
"The screw drive is different, it can Adjust the shaking direction of the spoon as quickly as possible to achieve balance. The volume occupied by the screw drive is much smaller than that of a pile of gears."
Chen Xihe joked: "You can't hold a spoon handle as thick as a tea cup." ps. : Thanks to Xuanzhi for the reward
