"Seek knowledge from the world!"

On the wall of the courtyard of Yishu in Wenshan, there is such a sentence written, although "Wenshan" comes from the word Wen Tianxiang, but here, what is learned is by no means folded, although there are Confucian masters who fled from Anhui, Jiangsu and other places in Yishu, but at the same time of teaching juvenile Chinese culture, they are more learning Western modern scientific civilization, and Chinese culture is more just a kind of inheritance here.

In a way, Wenshan Yishu is both China's first university and a vocational school, and in the past two years, it has trained thousands of students who are now working as grassroots technicians or managers in arsenals, chemical factories, iron works, silk factories and many other factories. More practical than any other school, and as the Governor's needs grew, new departments were constantly being opened, such as the telegraph major that was opened last year, that is, the training of telegraph operators, and the training of telegraph equipment technicians.

Antonio, the technical director of the telegraph office? Meucci has been training telegraph technicians here since the establishment of the telegraph specialty, and under his guidance, the first telegraph machine was built in the arsenal as early as last year, thus replacing the import of telegraph machines. In the past six months, the most important reason why the telegraph has been able to connect the cities and towns along the line from Guangzhou to Wuchang to the three provinces and provinces is that the equipment has been localized, and hundreds of technicians, including telegraph operators, have been trained.

But for Antonio? For his part, Meugch has been focusing on the research of "talkable telegraphs", and even through his own research prototype - because his wife is paralyzed in bed, as early as in the United States, Mewucci has installed a telephone system to connect his wife's bedroom to his studio for easy communication. That is, the humble prototype "telephone" received the investment of Handu, and the name of Handu-"telephone".

In the past six months, he has been studying the "telegraph" with his students, trying to put it into practice, and through continuous efforts, Mewuqi has made a great breakthrough, the new model has become more and more sophisticated, and the conversation has become clearer and clearer. Although Mei Wuqi feels that the use of the "phone" is getting better and better, for Zhu Yifeng, who is accustomed to the mobile phones of later generations, the phone in front of him does not surprise him, and tonight, he still sees the importance of the phone to the future.

"Now this telephone can only be used at fixed two points, can we consider researching a switching device?"

Putting down the phone in his hand in the laboratory, Zhu Yifeng reminded appropriately.

He was undoubtedly a layman when it came to telephones, and in the past, he only knew that telephones were invented by Bell, and never knew Antonio? More than 20 years ago, Mewuch had already invented the prototype of the telephone, and even put it into practical use. If it weren't for Antonio? Mewucci offered to show him a prototype telephone, fearing that he would also miss the invention.

But after learning that Antonio? After Mei Wuqi invented the telephone, Zhu Yifeng still gave some guidance, such as the reminder on the carbon crystal transmitter - there is a gap between the carbon crystal particles, and the gap is air, which is non-conductive. When the external sound wave pressure increases, the density of carbon crystal particles increases, that is, the gap between carbon crystals decreases, the resistance decreases, and the acoustic signal current increases.

In fact, the reason why the telephone is widely used is due to Edison's invention of the carbon crystal microphone. In the past, Zhu Yifeng only knew the principle - it was still thanks to the 80 editions of the 100,000 whys that he read when he was a child, and the knowledge that had become unpopular or even eliminated decades later was ahead of the times in this era.

Although the "why" in those memories is only the skin, for the people of this era, those "skins" are no less than God's flash of inspiration, and sometimes people make technological breakthroughs, relying on that 1% of inspiration. And the "100,000 whys" in the depths of memory are the "inspiration" that transcends the times for the technicians of this era. Just like what Zhu Yifeng is doing now.

"Swap devices?"

Whether it's Antonio? Mei Wuqi and the surrounding students all looked at Han Du in surprise. They apparently did not know what an exchange device was, and it was true that their ideas were still stuck in the telegraph.

"My thoughts are like this, that is, can the telephone be able to directly contact thousands of households, if it is like now, a pair of contacts, then who is likely to install a few or even dozens of phones at home?"

In their confusion, Zhu Yifeng explained while holding a pencil and drawing his own ideas on paper.

"Can you design an exchange device, like a junction box for wires, this junction box has many small round holes, each round hole corresponds to a telephone, through the line to communicate with each user's telephone. The user tells the call number to the switching station through the phone, and the operator can connect the phone between the user and the caller with a plug cord. However, it ...... to transfer calls manually "

Although this kind of manual transfer phone has the shortcomings of low efficiency, slow speed, and high labor intensity, and with the development of the times, it is increasingly unable to meet the rapid growth of call demand. But in this era, this kind of telephone, which uses a manual exchange station, is undoubtedly an epoch-making invention. Of course, it is important to note that the military application of the corded telephone will fundamentally change the way warfare is conducted.

The telephone allows the troops in the front to call for fire support directly, allowing the commander in the rear to give orders to the company platoon in the shortest possible time, thereby shortening the time for giving orders and avoiding missing fighters.

Hando's reminder made Antonio? Mewucci's eyes lit up, and he immediately realized what kind of changes such an exchange would bring to the telephone, which meant that the telephone could enter thousands of households.

"Han Du, if that's the case, the phone can go into the homes of ordinary citizens!"

"It's possible, but, Antonio,"

Zhu Yifeng shook his head and said,

"In the short term, due to cost constraints, it is unlikely to be popularized, well, and because the phone is directly invested by the government, it will not be declassified for at least the next ten to fifteen years, and it will be used as a confidential means of communication in the army and within the governor's office!"

Regardless of whether Antonio can understand the secrecy of the phone, Zhu Yifeng still made his request, the phone will bring a lot of changes, and because of this, it will be used as a confidential communication tool in the future.

A telephone is not the same as an electric light. The invention of the electric light cannot be kept secret, because the application of the electric light is public, in addition to the room, there are factories, streets, people have too many opportunities to come into contact with the electric light, what is the secret of the light bulb? Vacuum, carbon filament, only a few light bulbs, those foreign inventors can easily crack the "secret" of the light bulb. It is precisely because of the fact that the electric light is a "simple industrial product" and the fact that its invention is applied on a large scale and inevitably comes into contact with everyone, that Zhu Yifeng is more willing to exchange it for a richer return before outsiders crack his secret.

However, the telephone is different, and only the military and a few departments will use the telephone for a long time in the future, which means that outsiders have almost no opportunity to access the telephone, and the few people who can access the telephone are subject to the confidentiality system, so the telephone can be kept confidential for a long time.

"Of course, Your Excellency, everything is as you wish!"

Despite being a scientist Antonio? Mewuch hopes that the world will know about this invention and get honored. However, he also knew very well that without the 5,000 yuan subsidy provided by Handu, it would not be possible to have the current telephone. And he has already received his share of the reward - 50,000 yuan. This money is enough for him and his family to live a prosperous life, and he also used the money to buy shares in the railroad company, so he naturally would not object to the suggestion of secrecy. And since Han Du mentioned secrecy, there must be a reason for him.

"Wouldn't that be a bit of a broom?"

On the way out of Wenshan Yishu, thinking of his solemn advice on the secrecy of the telephone, Zhu Yifeng secretly thought in his heart, there is indeed a little psychology, but the telephone is different from the electric light, the electric light will not directly bring direct changes to the military, and it will not affect the army's operations. But as soon as the telephone was put into practical use, it was widely used in the military - first for the interior of warships, then for the communication between batteries and the rear, and later for ordinary army units. It can be said that the initial promotion of the telephone was not in the civilian but in the military.

Although this was influenced by the precedent of the widespread use of telegraphs in the Civil War, the military was more sensitive to advances in communications technology than any other person.

At least in the next 10 years or so, the armed forces will have technological superiority in communications.

More than anything else, that's the most important thing!

The carriage slowly walked towards the governor's mansion, and Zhu Yifeng kept thinking about the "One Hundred Thousand Whys" he had watched in his mind, and the content that should have been forgotten had actually been hidden in the depths of his memory. Thinking of reading that set of books at the beginning of the year, I simply let myself see another world, that set of books is really my own enlightenment books, in a small town where information is so backward and closed, so that a child will be curious and think from an early age, will ask why, will be full of curiosity about the world, and enrich the whole childhood. Zhu Yifeng's heart couldn't help but move.

"Maybe this era also needs a set of '100,000 Whys'." (To be continued.) )
