An extremely simple Chinese character instantly appeared in Xu Yun's mind:
grass!
mmp yo.
This is already the third time. What is this guy going to do this time?
Xiaomai's first ah-lie-lie appeared on the star-hunting night, when it led to Pluto's companion star...which is 'Charon'.
As a result, Gauss discovered the deviation in the calculation process, which forcibly promoted the "one-year agreement" between Xu Yun and Gauss.
The second incident occurred a few hours ago, which directly led to the foreshadowing of X-rays, which Xu Yun was originally scheduled to discover more than ten years later.
And this time...
What could it be?
It was Brother Lu who promoted the development of copies in the Northern Song Dynasty. Is Brother Lu an adult this time?
But then again.
There are only so many phenomena related to cathode rays, nothing more than electrons, Lorentz force and the derived X-rays.
Now that we have not really begun to study the microscopic world, Wheat should not make any scary remarks...
Bar?
Think of this.
Xu Yun couldn't help but take a deep breath, turned to look at Xiaomai not far away, pulled out a forced smile at the corner of his mouth, and asked:
"My Healing Game"
"What's wrong with you? Classmate Maxwell?"
At this time, Xiaomai was standing next to the operating table, with his right arm folded across his chest, his left elbow resting on the back of his right hand, his thumb gently touching his chin, with a thoughtful look on his face.
After hearing what Xu Yun said.
Mai turned his head and did not answer Xu Yun's question directly, but asked him:
"Mr. Luo Feng, if I remember correctly..."
"The calculation principle of the Analytical Engine designed by Mr. Babbage and others seems to be stored and operated through a scale?"
Xu Yun nodded and replied:
"That's right."
Mentioned earlier.
The Analytical Engine designed by Babbage had three modules:
One is the gear-type "storage library", the second part is the so-called "computing room", and the third part is similar to the controller in a computer.
Gears are used for storage, small hammers and pointers are used for calculations, and power comes from steam engines.
Then Mai asked again:
"High-intensity calculations require a large number of scale gears, which are extremely large and the combination is very complicated?"
Xu Yun nodded again:
"That's right."
Wheat nodded slightly when he saw this, pointed at the vacuum tube on the table and said:
"In that case, Mr. Luo Feng, I have an idea..."
"In order to maintain a high vacuum for the Xiao Yan tube, we first filled it with mercury, and then we just had to extract the mercury when needed."
"So if we don't pump the mercury and give it some kind of delay..."
"So theoretically, is it possible to use the electrical signal of the Xiao Yan tube to replace the information reception of the pointer and gear?"
When Xu Yun heard this, the fuck in his heart instantly turned into fuck.
A bad premonition vaguely arose in his heart.
However, he still tried his best to keep his face calm and said with a dry smile:
"Uh, classmate Maxwell, I don't quite understand what you mean..."
Xiaomai thought for a while, then simply picked up the paper and pen from the table and drew on the spot:
"This is an idea that just occurred to me. If we add certain indicators to the Xiao Yan tube... such as acoustic mercury or something, we can achieve the effect of delayed transmission of information."
"Then add a small component to control the current from the cathode to the anode, and transmit information by controlling the intensity of the current..."
"In this way, is it possible to achieve the same storage and calculation effects of gears?"
Xu Yun:
"...."
At this moment.
There was only one thought in his mind:
Xiaomai, you with thick eyebrows and big eyes are not also a time traveler, are you?
Seeing that there was no opening for him in the micro field, this guy actually turned around and headed towards the macro field?
As we all know.
In the long history of human civilization, the history of science and technology undoubtedly occupies a large amount of space.
In the history of science and technology, computers are well-deserved one of the protagonists, and can even be regarded as the number one.
The development process of computers can be divided into several periods:
Primitive period, tube period, transistor period, integrated circuit period, VLSI period, intelligent computer period and unknown computers in the future.
Among them, the primitive period and the electronic tube period are only separated by a period. In history, the two are dated for more than a hundred years!
The beginning of the primitive period was in 1642, when the Gauls Pascal invented the "adding machine".
This tool rotates with gears and can calculate the addition of 8-digit numbers. The Gallic government at that time also purchased fifty units of this device.
After that came Leibniz, Bujo’s punched paper tape method, and Babbage and Ada who really used codes as logic—that is, around 1850.
What about the tube era?
This thing appeared in 1947!
There is a whole century difference from 1850!
In the future, be it the transistor era or the integrated circuit era.
Even counting the span of the intelligent computer era, the total is not as long as the gap between the primitive era and the electronic tube era.
As for vacuum tubes and electron tubes...especially electronic diodes, the difference between the two is actually not big.
Not to mention that the current vacuum tubes are still modified versions.
Even if you insist on saying it.
The difference between a vacuum tube and an electronic triode is actually a grid - and the grid had already appeared as early as 1821.
So what can I say...
If we simply discuss the overlap of principles, there is indeed a certain overlap between vacuum tubes and Babbage's Analytical Engine.
And Xiaomai happened to be a big shot in history who was famous for his imagination.
Don't say anything else.
Just because he can derive Maxwell's equations and calculate the speed and properties of electromagnetic waves before they are discovered, his imagination is basically at the level of a circle around his neck.
Therefore, it seems quite reasonable that Wheat can discover the connection between vacuum tubes and analytical machines?
This chapter is not over yet, please click on the next page to continue reading! But Xu Yun felt so scared...
be honest.
He can barely control the current situation, after all, it is difficult for a qualitative change to occur in one day, two days, one year or two.
But once your mission is completed and you return to reality...
hiss--
Think about it.
Mavericks has corrected the wrong view of absolute space and time and proposed the wave-particle duality of light, which is the basis of everything.
Then in this era, the speed of light was remeasured, the photoelectric effect and electromagnetic waves were discovered, and then the charge-to-mass ratio of electrons was detected, and X-rays were 'accidentally encountered'.
If you add another computer...
Oh my god.
In this future timeline, there won't be psychic ascension, right?
But no matter how panicked Xu Yun was, at this time he no longer had the ability to correct history:
These big guys present are all top figures today and in the future. They have a strong sense of understanding and self-analysis, and can independently make various accurate judgments.
This ability can be said to be a double-edged sword.
When Xu Yun was doing experiments.
It can help these big guys quickly understand the essence of the phenomenon, and it can be understood in one click without the need for detailed explanation step by step.
But outside of the experiment, especially when someone proposed a certain idea, it was difficult for Xu Yun to find some flimsy excuse to deceive them...
So after Mai expressed this idea.
Faraday, Gauss and the others quickly went through wheat's words in their minds, and their eyes became brighter and brighter.
Less than half a minute passed.
Faraday put down the bottles and jars in his hands and asked Xu Yun:
"Classmate Luo Feng, I heard that Babbage and Ada have settled down?"
Xu Yun sighed as if he was resigned to his fate, and replied obediently:
"Well, Mr. Charles and the others moved to Cambridge half a month ago, and officially started the research on the Analytical Engine last week."
Faraday nodded slightly.
He had a very good relationship with Ada's teacher, Marie Sommerville, and there were even some side stories about Faraday and Marie Sommerville in later generations, so his relationship with Ada has always been good.
in the original history.
Faraday also wrote to the British government many times, hoping that officials would invest in Babbage and Ada again.
However, the British government had already suffered a setback with Babbage, and the British government had lost trust in Babbage.
For example, the then British Prime Minister John Russell once wrote back to Faraday, saying:
"If you are willing to personally be the person in charge of the project, the government can guarantee a capital investment of no less than 20,000 pounds, but if you are just lobbying for a certain person (referring to Babbage), then my answer may make you
disappointed."
Later, Faraday also gave Ada and Babbage two hundred pounds, but the effect was only a drop in the bucket.
Some time ago, he learned from Gauss about Cambridge University's investment in Babbage, and wrote a letter of congratulations to Ada.
It's just that these days, he has been preparing a paper on the photoelectric effect, so he has never had time to meet Ada.
Then Faraday pondered for a moment, lowered his head to discuss with Gauss and Weber, and then said to Kirchhoff:
"Gustave, it looks like I'm going to have to make another hard trip for you."
Kirchhoff quickly bowed slightly and replied:
"It is a great honor to be able to contribute to the professor's work."
Xu Yun noticed that when Kirchhoff said this, his eyes also shone with excitement.
After all, in history.
This young man who speaks with a strong German accent is also a master of circuit science.
He often tinkers with relays in his spare time, and has actually made profound theoretical achievements in binary algorithm research.
It's a pity that he has never found the right direction, resulting in a lot of theory but no practical direction.
In the end, those manuscripts can only lie alone in the display cabinet for future generations to remember and admire with regret.
But now that Kirchhoff has stayed in Cambridge as a teaching assistant, perhaps his life trajectory will also change...
His eyes returned to reality.
After receiving Faraday's instructions, Kirchhoff hurriedly left the laboratory.
Xu Yun took advantage of this free time to carry another eel that was not exposed to the mysterious ray, and made steamed eel with soup sauce for everyone.
The preparation of this dish is relatively simple, just three steps:
First, cut the eel into bones, add salt and soy sauce to taste, and fry in oil to remove the fishy smell.
Then let the skin set its shape to lock in the moisture and flavor, roast the meat, add garlic and oil to enhance the aroma, then simmer until the bones and meat are just separated, remove from the pot, carefully remove the fish bones and replace them with ham.
Finally, add lard, roasted pork, mushrooms, and tangerine peel and simmer for 30 minutes before serving.
Of course.
Due to material issues, Xu Yun used lemon peel instead of tangerine peel and Iberian ham instead of Jinhua ham. The taste will not be too different.
The fragrant eel meat is served with bread from the cafeteria, and even an old man in his 70s like Gauss eats it happily.
after an hour.
A hungry Kirchhoff took Babbage and Ada back to the laboratory.
Than when we first met.
Whether it is Babbage or Ada, their skin and mental state are much better.
When he saw Ada, Xu Yun had another thought in his mind:
I should take the time to check out what Liszt is doing there...
And the other side.
After entering the laboratory.
Babbage came to Xu Yun in one stride and asked:
"Classmate Luo Feng, where is the tube that Mr. Gustav said can optimize calculations? I want to mess with it!"

Note:
Some readers have been concerned about my childhood incident. The situation is currently going smoothly and there is no life-threatening situation. The main reason is that the other party is a family with many relatives. Some people can communicate normally but others are very fierce, so they are still mediating.
There is nothing to say about responsibility. The other party's tricycle is driving in the wrong direction and is overloaded. However, some things are easy to say, but in practice you really have to run around...
If nothing else happens, I will probably be back the day after tomorrow. I am running around on a hot day, so please forgive me for the lack of updates.
