There are not many books in the army, but the old military industry has subscribed to a lot of magazines, which is exactly what Cao Changjiu's appetite is. Cao Changchang has become a frequent visitor to the old military industry's home, and everyone is familiar with each other after coming and going.

The old military workers who have no children and no daughters also feel very fond of Cao Changjiu's love of reading magazines so much, and often discuss with him the latest foreign scientific and technological progress published in magazines.

Once, the old military worker took a copy of the latest "Radio" and pointed to a picture and asked Cao Changjiu: "Baby, tell me, what is this?"

Cao Chang glanced at it and said, "Oh, it's a computer." ”

"What's the brain, what's the use? I see that this thing uses hundreds of thousands of integrated circuits, and it's scary. You say that American devils are really rich, how much does it cost? ”

Cao Changjiu smiled: "Uncle, this is a computer, but it is very useful, with this thing can you build atomic bombs, hydrogen bombs, rockets or something." As he spoke, he took the book and looked at it carefully, "Oh, it's the world's fastest computer made by the United States, the Clay-1, which can calculate hundreds of millions of times per second." ”

The old military industry was obviously a little confused: "Hundreds of millions of calculations are over in one second? If you count the trajectory of the cannonball, it's not a blink of an eye. We don't know if there is. ”

Cao Changjiu was also a little distracted, yes, with Huaxia's level of science and technology, it is indeed impossible to build this kind of computer hundreds of millions of times, let alone hundreds of millions of times, there are no tens of millions of times.

Western countries relied on the industrial revolution to complete the current world pattern, and China did not take this bus and became a semi-colony. And now is the beginning of the revolution, but the subject is integrated circuit computers.

Cao Chang couldn't help but think of the era in his dream, when Huaxia could be said to have gotten up early in the morning and rushed to a late meeting in the computer age, but was left behind by the great powers and embarked on the old road again. Shame is unbearable for a Chinese person.

The dawn of the information age is just around the corner, and developed countries have the conditions to start researching computer application technology.

The terrible thing is that if other high technologies have their own reasons, then the research and development of supercomputer technology in China is a little embarrassing. The purpose of the Americans' development of computers is to apply them, and their developed social and economic strength has created a demand for this. The advent of computers has promoted the development of the industrial economy, and the two complement each other.

In the early days of China, however, it seems to have embarked on a wrong path, not paying much attention to the application of computers, or not knowing how to apply them at all, so they despised the development of software, and did not integrate it with modern industry at all, and computer research was only carried out alone under the will of the state, and only thought of how to improve the speed of computing, and its software achievements were only made in a few fields such as oil exploration and earthquakes.

In the early days of the computer age, large and medium-sized computers dominated the world, and the cost was amazingly high, which naturally limited the application field, and even the economic strength of the Americans could not afford it. The achievements of industrialization have realized the integration of technology, the emergence of microcomputer systems is the driving force for the general promotion of the whole society, and the large-scale computer has been further specialized, sticking to the fields of scientific research, industry, and commercialization.

In the 77 years of China, just like the early days of the industrial country, computers were available, and efforts were made to improve the computing speed of computers, and it was difficult to develop computer applications in various industries. However, due to the limitation of the industrial base of the whole society, the computer is still unstable, the speed is not high, and the application is not many and complex, which is not as good as manual labor for industrial workers with low cultural level.

For a long time, I thought helplessly, Huaxia is still in a strange circle, and scientific and technological achievements are still not transformed into productive forces.

The old military worker looked a little distracted for a long time and asked, "What's wrong with you, are you uncomfortable?"

After coming back to his senses for a long time, he smiled and said, "No, hehe." We also have this kind of computer in our country, but the performance is not as good as that of the devil. ”

Unexpectedly, the old military industry said with pride: "Of course, the chairman has said that the wisdom of the working people is infinite, and when the founding of the People's Republic of China was founded, we had nothing, and now we can't build anything! This is not a problem." ”

If you think about it for a long time, it is only a few decades since you went from being poor and white to having a complete industrial base, not to mention that China's computer technology is not very backward now, so what reason is there to think that it can't be done?

The old military engineer asked reluctantly: "Tell me, what can this computer do?" ”

After thinking for a long time, he said: "Let's take an analogy, what is the process of our artillery to hit the enemy?"

The old military engineer said: "First reconnoiter the enemy's position, give the reference coordinates, and then we will calculate the design parameters before fighting!"

Chang smiled and said, "Then how long will it take!"

The old military engineer thought for a while: "If you don't count the reconnaissance time, it will take more than ten minutes." ”

"That's right!" he patted the table for a long time, "manual calculations have to be so slow, and this is not the case if you combine computers with radar and artillery." For example, our army attacks the opponent's position, and the enemy's artillery position threatens our army, and we don't know where. What to do, you have to rely on scouts to scout and fight until the year of the donkey. It's not the same with a computer, the enemy shoots artillery, the radar scans, all the data is sent to the computer, and you can calculate where the enemy is firing from in seconds, and then calculate the design parameters of our side, at this time the artillery is either manually operated or the computer directly operates the artillery, and directly puts the enemy's artillery position to the end. ”

The old military engineer was dumbfounded: "Obediently, according to what you say, it was less than 5 seconds from the time the enemy fired the first shot to before and after we returned fire, so fast!"

"It's that fast! This is just a real-time control of artillery ballistics calculations, as for other military production design, aerospace roles, and so on, with the development of computers, there is no one in the factory, and the computer controls the production of a water. As soon as Cao Changjiu was in a good mood, he began to flicker.

The old military engineer was stunned: "No one? ”

"Play, it's all computer-controlled, what else can you do. Cao Changchang said with a smile.

The old military engineer was shocked, and said with a yearning face: "I really hope that we will have a computer sooner, and we won't have to be so tired to fight artillery." ”

smiled weirdly for a long time: "We can do computers, we can do cheap ones if they are expensive, and we can do semi-automatic ones if they are fully automated." ”

The old military industry was completely nonsense: "Didn't you say that this computer costs a lot of money?

Scratched his head for a long time: "We are too advanced to do it, look at those soldiers who calculate the trajectory of the calculations, it is very time-consuming, I thought that I could make a simple calculator, as long as there are parameters, you can directly calculate the shooting elements." ”

The old military worker felt a little interested, and hurriedly leaned in and said, "Can you make this kind of thing? Count me in, it's really a great merit to be able to make it." ”

Long stretched out his hand and patted the old military worker on the shoulder: "Well, it's good, follow me in the future, and you will have immeasurable merit." ”

The old military worker picked up the magazine and patted it on the head for a long time, and scolded with a smile: "Little rabbit, it's not big or small." ”
