The second thing Wang Xuexin did was to call Ban Haolin and Chen Jiefeng, who were studying with Qiong.
The reason why we were looking for them instead of Turing or Qiong was that this was a military secret and nothing could be revealed to the sun.
On duty, when Chen and Chen stood in front of Wang Xuexin, Wang Xuexin first exchanged a few words with them, and then said in a tone of testing them: "Boss, if we know the two points on the parabola and want to calculate the entire parabola,
,can it be done using a computer?”
Wang Xuexin originally thought that Ban and Chen would say "yes", but unexpectedly they answered without any hesitation: "No!"
"No?" Wang Xuexin frowned upon hearing this.
He thought that Ban and Chen had not learned anything from Qiong, but Ban Haolin hesitated and explained: "Captain, to determine the trajectory of a parabola, you must... know three things!"
Wang Xuexin said "Oh", it seemed like this... Two points can determine a straight line but not a parabola!
I only blame myself for not learning math well at the beginning, so I could even get this wrong.
Su Liguo was not a math major, and basic science education had not yet been popularized in China at this time, so no one discovered this error for a while.
So the speed of the radar needs to be accelerated, otherwise it will not be able to detect three points... I will give Su Liguo a warning later!
Wang Xuexin composed himself and said with a slight embarrassment: "So, if you know the three points, can you calculate it?"
"Yes! Of course!" This time Ban and Chen nodded happily.
Wang Xuexin asked again: "Can you do independent wiring?"
This is slightly different from modern computers.
Modern computers are programmed to calculate, but computers of this period needed to be wired in advance according to certain rules.
When Wang Xuexin said this, the talkative Ban Haolin started talking.
"Captain!" Ban Haolin said: "Speaking of which, we have to thank you. If it weren't for the 'C language' you invented, we would have been confused for a long time and couldn't find it. At that time, if you asked us what we could do
If we can't solve this problem, we are really not sure! But now... this is just a small problem!"
"Yes!" Chen Jiefeng also nodded confidently: "Being able to complete it independently is just a matter of time at most. Test it a few more times. If the result is wrong, we will spend more time looking for the error, and it will always be solved!"
"That's good!" Wang Xuexin nodded.
This problem is indeed not difficult for programming. Wang Xuexin believes that Ban and Chen can do it, otherwise they would not be worthy of being called mathematicians.
Then Wang Xuexin asked another question: "So, what if electron tubes are used instead of relays? Can you do it?"
It is not impossible to use relay computers to calculate ballistics for artillery detection radars. In fact, the calculation speed of relay computers is sufficient. The problem is that relay computers are large and heavy. Any calculation unit is as big as a house of more than ten square meters.
This is obviously not suitable for land operations, especially artillery operations.
Moreover, the development of computers will develop in the direction of electronic tubes sooner or later. If China wants to have a technological advantage in this regard, it must be ahead of others.
Wang Xuexin's words made Ban and Chen stunned on the spot. After looking at each other, they each replied:
"Captain, isn't this a little ahead of its time? We haven't developed the relay computer yet!"
"Yes, leader! The sun never sets and we have just reached the stage of relay calculation. Are we starting to work on electronic tubes?"
It's no wonder that the two of them thought so. At this time, the gap between China and the Western powers was so great that even Chinese intellectuals dared not look directly at it. As a result, over time, the idea of "only learning but not surpassing" was generally formed.
It means that it would be great to learn from the great powers, but still want to catch up? Just dream!
If it were in the past, objectively speaking, what Chen and the two said was indeed correct. At this time, China should take it step by step and slowly, and not rush for success and think about making electronic tubes before the relay was developed.
But things are different now. Wang Xuexin, a modern person, knows where computers will develop and how they will develop... You would be a fool not to develop ahead of the curve.
Wang Xuexin believed that it was time to build up the self-confidence of Ban and Chen, so he said unhurriedly: "The reason why you two, Qiong and Turing and other technical staff who never set the sun, did not tell you too much
, it’s because this project is top secret that the sun never sets, which is why you two misunderstood!”
"Misunderstanding?" Chen Jiefeng heard the implication of Wang Xuexin's words. He asked doubtfully: "Captain, what do you mean by this..."
Wang Xuexin did not answer and asked instead: "You guys think, why do these scientific researchers come to China? As they say, they help our army decipher the Japanese code? If it is just to decipher the code, why did Turing invent the 'universal decoding machine'
Are you still coming here? Why are you starting research on relay computers in China and are you willing to cooperate with China? Have you thought about these issues?"
How could Ban and Chen think of this when they were focusing on research work during this period. When Wang Xuexin said this, they found it really puzzling.
Especially the relay computer... There is no need to cooperate with Huaxia because the sun never sets, because Chen and Chen are studying during the whole class, and they basically don't help much in research and development.
Why would the sun never set such an advanced technology to China? He even led the class like an apprentice. What about the two Chens?
Wang Xuexin waited for a while and met with the class. Chen and the others had no clue about these issues... It was not that they had no clue, but they simply dared to imagine that China could surpass the sun never sets in this regard.
Then Wang Xuexin gave the answer: "Because we provide relay computer technology to the sun never sets!"
Ban and Chen were instantly shocked and speechless.
After a while, Ban Haolin stammered: "Tuan, head of the group... This, this is wrong! If we have... this technology, then why do we have to learn from them?"
"We have the technology but not the equipment!" Wang Xuexin replied: "As you know, the relay computer has very high requirements for the reliability of the relays. We cannot guarantee that so many relays can work at the same time, so we have to cooperate! That's why you can follow the sun.
Develop together!”
Ban and Chen still couldn't believe it, but... only in this way can all these questions make sense! So there is no room for disbelief in this matter.
Finally, Wang Xuexin said: "Now, do you still think we can't catch up before the sun sets? Do we still have to stop and wait for them?"
