The Red Era, the Opening University Speech

Chapter 122 D-Ballistic Trajectory Calculation

Facing Song Jianxia's question, Li Mu hesitated for a moment, then said:
"Since you, Leader Song, have spoken, I will venture to say a few words."

"As research in the semiconductor field continues to deepen, chips will be used in more and more fields and their integration will become higher and higher."

"In the future, perhaps a palm-sized box will be able to realize long-distance mobile communication between people."

After he finished speaking, Wang Shoujue in the conference room seemed to be thinking about something, while other leaders such as Qiu, Liu Weiguo and others were shocked.

A palm-sized box can achieve communication, which has extremely important value both in military and civilian use.

Song Jianxia was keenly aware that Li Mu said a word: "Mobile communication, what does that mean?"

"Can I make a phone call while walking? How long of a phone line would that require?"

As the leader of the Postal Bureau, he was certainly familiar with the communication technologies and methods of various countries.

When it comes to mobile communications, only the telegraph is available. Not only is it large in size, it also requires a special code book for translation.

Even if you can communicate while walking, it is still very inconvenient.

"Of course not. In fact, the principle is similar to that of a telegraph, but it uses the principle of sound-to-electricity conversion."

"The sound on one device is converted into an electrical signal, which is transmitted to another device through a wireless signal transmitter and then converted back into an acoustic signal."

"This not only enables long-distance communication, but also makes communication more convenient and faster."

After listening to Li Mu's story, Song Jianxia opened his mouth in shock.

He wondered, "But in this case, wouldn't we need more equipment? How can we achieve mobile communication?"

Wang Shoujue had the same doubts, but he vaguely felt that this might be related to semiconductors.

Sure enough, Li Mu's answer the next moment confirmed his guess:

"This involves more professional knowledge. Simply put, with the development of semiconductors, all electronic devices will tend to be miniaturized."

"What can be done with a bulky machine now may be solved with a chip the size of a fingernail in the future."

The conference room fell into a long silence as Li Mu explained.

After a while, Song Jianxia said, "If this is true, then the emergence of communication chips can be said to be the beginning of a scientific revolution in our country!"

……

After all parties were satisfied and left, Comrade Xu from the First Ministry of Machine Building in Kyoto found Li Mu and asked if it was possible to sell the programmable digital switching system abroad.

Li Mu certainly agreed. No matter how advanced the programmable digital switch is, it needs to be popularized to play its greatest role.

But the country certainly cannot allocate so much funds now, so they can only find a way.

Foreign program-controlled digital switches will not be available until four years later, so we can take advantage of this opportunity to make a fortune and sell our products to them.

……

Afterwards, Li Mu visited the J language research group.

The current J language research group has expanded to twenty people.

Walking into the laboratory, Li Mu called out to Wu Xi, who was leading the people sent by Guo Mo to study, and the latter immediately ran over quickly.

Seeing how respectful Wu Xi was to Li Mu, many students who had just entered the Semiconductor Research Institute were stunned, with a lot of question marks in their heads.

"The army asked us to improve the stability of the programmable digital switch..." After telling Wu Xi about Liu Weiguo's request, Li Mu asked about the team's current research status.

After learning that everything was going well for the time being, he said goodbye to Wu Xi and prepared to leave immediately.

As for Wu Xi asking him to stay and help teach the new students?

Li Mu quickly shook his head and threw the thought out of his mind.

He doesn't have the nerve to do that.

……

In the afternoon, Li Mu was preparing to go home. Just as he walked to the school gate, he met Sun Fendou.

The latter mysteriously took him to a deserted place and told him the news that the ginseng seller had been found.

"Then let's go now." Li Mu thought about it and decided that physical problems should be solved as soon as possible. The sooner they are solved, the more peace of mind they will have.

Afterwards, he followed Sun Fendou through the alleys of Kyoto. After more than an hour, the two arrived at the gate of a small courtyard.

Sun Fendou knocked on the door four times of varying lengths. After a while, a muffled voice came from inside, asking, "Who is it?"

"I." Sun Fendou responded concisely.

After a while, the sound of the bolt being pulled was heard from inside.

With a "creak", the door was opened, revealing the face of a tall man wearing a cotton coat and with a scar at the corner of his eyebrow.

He first glanced outside the door cautiously, and after seeing that there was no danger, he said, "Come in."

This cautious look made Li Mu feel like he was acting in a spy movie.

But it's normal when you think about it. Private transactions were not allowed in that era, and if you were caught, you would be put in prison.

"Where's the money?" the tall man asked immediately after entering the house.

Just as Li Mu was about to pay, Sun Fendou said, "You asked that question. You have to let us see the goods. What if you got a fake one?"

When the tall man heard this, a gleam of light flashed in his eyes, but in the end he said nothing and silently took a package from the windowsill in the house.

"50-year-old Changbaishan aged ginseng." He opened the package and revealed the contents.

Li Mu didn't understand at all and could only look at Sun Fendou.

The latter looked at it for a long time, knocking until the tall man was a little annoyed, and then he said, "Name a price, how much?"

"100 yuan. If you have national food coupons, it can be cheaper." said the tall man.

Hearing this, Sun Fendou said, "It's higher, 70."

"No, at least 95."

……

The two men fought back and forth, and Sun struggled to get 85, but the tall man insisted on 90.

"I won't sell it for less than 90!" As he spoke, the tall man became angry and suddenly put the package away, preparing to drive the man away.

He felt that the two of them had no intention of buying it at all.

"90 yuan, I want it." Li Mu said quickly when he saw this.

Hearing this, the tall man was stunned. Sun Fendou had been talking since he came in. He didn't expect that Li Mu was the buyer.

"I'll give you the money and I'll give you the stuff." Li Mu took out money from his pocket, counted out 9 10-yuan bills and put them on the table.

Then he went to get the old mountain ginseng.

However, the tall man stared at the remaining stack of money in Li Mu's hand, and a hint of greed flashed in his eyes.

Seeing this, Sun Fendou's face changed slightly.

"What are you standing there for? Give it to me!" Li Mu pulled it out but it didn't move. He then used a little force and the latter staggered with a look of astonishment.

The tall man looked at the package taken by Li Mu in disbelief. Even if he didn't pay attention, he shouldn't have been easily pulled down by a student-looking guy.

"Okay, the money and goods are settled, let's go." Sun Fendou hurriedly pulled Li Mu away.

Although I don’t know why the tall man suddenly suppressed the greed in his eyes, there is definitely no benefit in staying there.

Although he is quite strong, the tall man looks difficult to deal with, so it is better not to seek trouble.

The tall man watched the two people leave without making any move. …

After leaving the house, Sun Fendou took Li Mu away for a while, and said with lingering fear: "I was scared to death. The person introduced by this old Wangtou turned out to be unreliable."

"I will definitely talk to him about it later!"

After hearing his words, Li Mu, who was about to break off a root of old mountain ginseng to taste, belatedly asked, "That guy wanted to rob us just now?"

"It's my fault. I forgot that wealth should not be shown off."

He was just concentrating on what changes would happen after eating the old mountain ginseng, and he didn't really notice the tall man's expression.

The main thing is that this is the first time he has encountered someone trying to rob someone during a transaction.

"It's also my fault. I forgot to remind you, otherwise this unlucky thing wouldn't have happened." Sun Fendou said.

Li Mu thought for a moment and said, "It's quite unlucky. Come on, Brother Sun, I'll treat you. Let's go to a mutton restaurant to get rid of the bad luck, how about that?"

"Okay, I rarely eat at a mutton restaurant once a month." Sun Fendou's eyes lit up when he heard that, and he immediately put the matter of the tall man out of his mind.

Fortunately, nothing happened.

……

The tall man here was stunned for a while, then quickly packed up his things and prepared to hide somewhere else.

He was just tempted by the money, and the young man didn't notice it, but the man who was following him and fighting with him for a long time must have noticed it.

For safety reasons, you must leave immediately.

But just as he reached the door, his ears suddenly moved and he heard some noise outside.

The moment he realized that something was wrong, the tall man immediately retreated back into the house and tried to escape through the window.

However, just as he climbed out of the window, several guards in khaki clothes rushed over and said, "Be quiet and don't move!"

Before he could react, the tall man was pinned to the ground, unable to move.

……

Li Mu didn't know that the tall man was arrested by the Security Committee as soon as he left.

After eating mutton hotpot with Sun Fendou and chatting about all sorts of things under the sun, he returned home.

I cut a little bit of old ginseng, boiled it into soup, and drank it in one gulp. It warmed my whole body.

"It seems to be of some use." Li Mu felt that he had strength all over his body and immediately sat down and started studying.

Of course, before studying, you still need to sort out your recent plans.

The programmable digital switch and J language were just the beginning. His ultimate goal was to develop an integrated circuit computer.

"Unfortunately, it will take time to improve the level of integration. It will be useless even if I come up with the technology." Li Mu sighed slightly.

Improving integration is not something that can be achieved overnight by simply coming up with some technology. After large-scale integration is achieved, the speed of subsequent improvements will slow down.

Materials, experience, technology, equipment, etc. are not problems that can be solved immediately.

"It's okay. I'll continue to acquire knowledge about integrated circuits and computer chips, and try to produce them as soon as the conditions are ripe!" Li Mu secretly encouraged himself.

Just when he was about to continue studying, a rapid message alert sound suddenly rang in his mind.

Ask: "Li, hurry! I went to the supermarket to buy things today and met a girl. Do you think she likes me?"

"The three biggest illusions in life are: my phone is vibrating, I can fight back, and she likes me." Li Mu responded while holding back his laughter.

"No, no, no, she looked at me for a long time and called me cute. She must like me." Ask said excitedly.

"Cute? Then you have no chance." Li Mu shook his head.

When a girl praises you for being cute, the best outcome for you is probably to become her best friend.

"I don't believe it. I even plucked up the courage to ask him for his phone number, and he gave it back to me!" Ask said unconvinced.

Li Mu: "Why don't you give him a call and try?"

There was no reply from Ask, probably he was on the phone.

He didn't wait and learned on his own first.

Just before going to bed, Ask replied to two messages: "Crying JPG crying JPG crying JPG!"

"She said my zipper was unzipped and SpongeBob was showing inside!"

……

The next day.

After washing up, Li Mu headed to school while yawning.

Last night, I spent a long time comforting Ask, who had just broken up with his lover, and taught him a lot of love skills, which made me not sleep well.

Walking into the Beijing Institute of Technology, you can still hear people discussing programmable digital switches and J language everywhere:
"Number one in the world! That's amazing! The M-emperors can no longer be so arrogant!"

"And he is from our Beijing Institute of Technology. I am proud to be a member of my alma mater!"

"I just don't know which professor it is. Sigh, do you think it could be Professor Zhang, or Professor Wei..."

……

Listening to the flattery around him, Li Mu felt embarrassed.

I'm afraid others would never have thought that it would be him who created the J language and communication chip.

But it’s better this way, so I don’t get targeted by the transport captain.

Just as he was walking and distracted, someone suddenly patted his shoulder.

Turning around, I saw Wang Ya's bright smiling face.

She asked, “How does it feel to be praised by so many people?”

"Not bad." Li Mu told the truth.

Being able to contribute to the country and getting recognition from everyone is a sense of satisfaction that cannot be compared to any other fun.

"I thought you would be disappointed. After all, many people don't know it was you who did it." Wang Ya said.

Li Mu smiled and said, "There's nothing to be disappointed about. Besides, it would be very dangerous if others knew about it."

"Look at Professor Huang. His name has appeared in the newspapers twice. He has been going out less frequently recently and just stays at school doing research."

"If my name gets out, it might be even more dangerous."

Hearing this, Wang Ya reacted and lowered her voice: "Then what I just said will not be..."

"You don't have to worry about school." Li Mu comforted.

After that, he asked again: "By the way, you didn't come here just to tease me, did you?"

Hearing this, Wang Ya straightened her face slightly and said:

"Yes, you recommended me to the 421st teaching and research group of our school. Now the project of calculating the trajectory of the D-bullet has been started."

"But it will take some time for the professors to learn the J language, so I thought I'd ask you for your advice first so I can be prepared."

Li Mu did not answer first. He took a few quick steps and sat down in a pavilion on the side of the road.

He took out a pen and manuscript paper, frowned slightly, and then wrote as he spoke:

"Let me first tell you about the factors involved in calculating the trajectory of the D-missile, including the type of missile, guidance method, and power unit..."
