Maxwell, who was reborn under the education of the Red Celestial Empire, together with his colleagues in the laboratory, under the diligent guidance of Zheng Nan, "the only and greatest scholar in the world today", after nearly a year of hard work, according to Zheng Nan's theory, not only through their carefully designed "oscillating dipole" (the most primitive radio transmitter) and "resonant dipole" (the most primitive radio receiver), but also finally succeeded in detecting the storage of electromagnetic waves (at a distance of three meters from the oscillating dipole, From the gap between the two small copper balls of the resonant dipole, a jumping spark was observed. This faint electric spark confirms from scientific practice that Zheng Nan's theory that a changing magnetic field can produce an electric field, as long as there is a changing magnetic field somewhere in space, and the latter will provoke a new changing electric field at a greater distance...... And so on and so forth, the electric field produces a magnetic field, and the magnetic field produces an electric field. In this way, the changing electromagnetic field will propagate in the air from near and far, forming a special wave. Therefore, electromagnetic waves are essentially alternating electric and magnetic fields, and propagating from near and far to the surroundings. Just as a certain water molecule vibrates up and down, thus driving the neighboring water molecules to fluctuate and vibrate, thus forming a prophecy like water waves, announcing the arrival of a new technological era -- the era of radio electronics), and repeatedly studying and improving the "radio conductor", that is, the "powder detector", which really opened the door to putting electromagnetic waves into practical application.
Using "powder detector" technology, Maxwell and his colleagues successfully prototyped the first receiver. At the same time, the French scholar Rumenkov used the high-voltage transformer (R) technology with an iron core that he had designed in Paris as early as 1851 to connect the Morse telegraph key with the primary coil of the R. When the Morse telegraph key is pressed, the primary current of the transformer is periodically turned on and off by a "disconnector" similar to an electric bell, and each break generates a high induced voltage in the secondary coil of R, so that an electric spark is generated between the two small balls connected to the secondary coil, and electromagnetic waves are emitted into the surrounding space through the antenna hanging outside the Guò. Completed the trial production of the first-ever transmitter.
On September 18, 1856, a tall antenna was erected on the main building of the Tianjing Academy of Sciences, and in the real yàn room, under the concerned eyes of Zheng Nan, Yang Xiuqing, Shi Dakai, three leaders of the Celestial Empire and their colleagues, Maxwell personally operated, and successfully achieved historic radio communication with Zhenjiang, hundreds of miles away.
In order to forever remember Zheng Nan's great contribution to mankind and science, all the colleagues of the Institute of Physics of the Academy of Sciences finally unanimously decided to officially name "Zheng Nan", the vibrational frequency unit "Zn", which they had been accustomed to using in private, despite the repeated "protests" of Vice Chairman Zheng.
“…… Under the leadership of this rare giant of science, you can't imagine how much pleasure it is to work here. His brain is like a perpetual motion machine that never stops turning, taking us to harvest a result and start a new round of sowing. This is truly the sacred temple of science, here, we never have to worry about the funds needed for scientific research, let alone consider whether our own life is perfect, they are using the speed of running to catch up with the modern world, they have already arranged for you to be so meticulous......"
This is a passage from Maxwell's letter to Faraday, a physicist far away in England. Thanks to his efforts, he once started with "I am an ordinary person. If I accept the honour that the Royal Society wishes to place on me, then I cannot guarantee my honesty and integrity, not even for a year. Turning down the offer of President of the Academic Council of the Royal Society and the President of the Royal Academy, and repeatedly politely declining the Royal Family's intention to confer him with the title of knight, Mr. Faraday came to China in the spring of 1859 at the age of sixty-six. Mr. Faraday, who was committed to scientific research and popularization, and Zheng Nan, whom he called "the greatest scientist", soon became the most irreversible friends, and left his tireless figure on the campuses of universities, primary and secondary schools in Shanghai, Tianjing, Beijing, Guangzhou and other places, and made indelible contributions to the development of physics, chemistry and the chemical industry of the Celestial Empire.
However, the fruitful autumn does not bring any sweetness to some people, and some are only indescribably bitter.
U.S. Minister to China Marshali is now one such one. At the beginning of the year, behind the vague market boom, there began to be some hints of the domestic economic recession, and after entering the second half of the year, it was more obvious. Encouraged and motivated by a large number of powerful new explosives from the Taiping Heavenly Kingdom, the enthusiasm for domestic investment in railway construction continued to rise. In addition, a large number of American companies have set their eyes on the grand blueprint for the construction of the railway and highway transportation network that has been publicized everywhere in the Taiping Heavenly Kingdom, and have hoarded steel in advance, making the British steel market, which is much cheaper than domestic enterprises, very hot for a while, causing the major British steel mills to work overtime and desperately produce food, and the stocks of steel companies are rolling upward.
Unfortunately, the good times did not last long, and as more and more goods were hoarded, the market demand became more and more light. No matter how hard the companies that hoard goods try their best, it seems that it has become an annoying stinky shit overnight, and everyone is interested. So, the last trick began, racing to lower the price. Even so, the bad luck of the steel market is still the same. Eventually, a chain of funds began to break one after another. The low-price and frenzied sales of British steel not only crushed the domestic steel enterprises, but also crushed the leather bag companies that were originally planning to rely on living money to make money. An economic crisis is coming! For Mashali, who lives in their world, the words "economic crisis" are not unfamiliar.
In the face of the increasingly severe economic situation in China, domestic politicians and experts naturally shifted their longing attention to the Taiping Heavenly Kingdom. According to a rough estimate by the experts, since the beginning of the previous year, the Taiping Heavenly Kingdom government has made a considerable amount of money from outside the country by relying on medicine, explosives, cigarettes, liquor, silk, tea, ceramics, and other consumer goods. Therefore, the Ministry of Foreign Affairs sent instructions to His Excellency the President to convey to Mashali that he must do his best to clear the Taiping Heavenly Kingdom, and as soon as their contract for the construction of a large-scale railway and highway network is in hand, the suffering United States will be saved, and you Mashali will be a national hero comparable to Washington.
"I really want to be this hero, but right now, I'd rather be a more ordinary person."
Ma Shali tore his thinning gray hair on his head desperately, and looked angrily at Jin Nengheng, the former Qichang Taipan who was invited by him, and now the general manager of the Oriental Company of the American Tianlong Group, with a helpless moan in his mouth.
Although Jin Nengheng's business is now a little lighter than before, after all, there are two big bosses with great powers behind him, Fang Jingbo and Sang Yu, even if there is no railway contract, relying on explosives, medicine, cigarettes, clothing, etc., he will not starve to death. However, there is never too much time to do business. Therefore, when he received the invitation of His Excellency the Minister to visit Vice Chairman Zheng together, he was naturally eager. When the company can make the government inseparable from itself, it is called excellent. He firmly believes that their Tianlong Group will not only be able to make the legation use itself as a crutch, but sooner or later, their president will have to enter the political circles, and the deep-pocketed Tianlong Group will finally be able to control the American government remotely.
However, after reading the president's instructions, Kim Nenghyung was also a little vague. From the bottom of his heart, among these leaders of the Taiping Heavenly Kingdom, the one he is most willing to deal with is the director Lin who is leading the troops outside, who is the one who commands thousands of troops and horses, who only looks at the big picture when he speaks and does things, and does not care about small things, and everything seems to be better negotiated. As for the one who is most reluctant to contact, it should belong to Vice Chairman Zheng who is about to visit him. This Vice Chairman Zheng is too small-minded and too calculating, and he can't wait to calculate everything in your bones, and he can't suffer a loss.
"Your Excellency, can we ......" Jin Nengheng put down the official document in his hand and shrugged his shoulders a little helplessly, "I mean...... Can we dredge from Shi Dakai first, hehe...... I always felt that it was easier to get in touch with their supreme military leader. ”
"It's useless...... Marshali stretched out his palm, looked at a lock of hair in his palm, and shook his head with a bitter face, "I have been there a few times before I saw the president's order, and he has made it very clear, although their Celestial Empire is fully recovered at the moment, the military task is still extremely serious." He believes that many hostile forces are still holding their hearts against them, and they always have their crooked ideas. Therefore, he will concentrate on military affairs, and as for economic issues, their chairman and Vice Chairman Zheng will be fully responsible. ”
After listening to Mashali's words, Jin Nengheng was stunned for a while, and then asked cautiously, "Didn't Your Excellency bring ......" His hand gestured, the meaning was obvious, it was suspected that Mashali, who was picking the door, must not have brought enough dredging "tools" when he went. If there is no profit, who wants to take care of your idle business.
"Alas...... I'm going to have to blush for days if you see what I've brought," Marshali began to tear his hair again, "I don't understand, he didn't even look at it. ”
"That'...... That's really ......" Jin Nengheng filed the tooth flower, then he could only ask to see Vice Chairman Zheng, compared to them, their chairman Yang Xiuqing's head was even more difficult to shave.
