Chapter 80 Pointing the Direction (Kneel down and beg for first order! First update)
When Li Qiwei was about to express his opinion, everyone looked at him.
Marconi’s eyes were burning and his face was full of excitement.
As a young man obsessed with physics, Li Qiwei's achievements were far beyond his reach. A casual sentence can last a lifetime.
Although his family was rich and he opened his own company, people like Li Qiwei were always the envy of Marconi.
Looking at everyone's reaction, Li Qiwei smiled softly and began to draw a picture, saying: "Langzhivin is right about the first question, which requires a separate device to control."
"Based on my understanding of the current industry According to the understanding of the industry, a breakthrough in electronic products should be achieved within five years at most.”
“Recently, I have cooperated with Philips in the Netherlands to set up a scientific laboratory, and one of the research and development goals is similar products. "
"That's why I have the confidence to make a prediction."
After thinking about it, Li Qiwei was ready to no longer hide it and directly create the triode in advance.
Because in 1906, the American inventor DeForest invented the triode based on the diode, thus starting the vigorous development of wireless electronics.
In just five years, even if he brought the triode technology back to China, it would not have any effect.
Because of the current situation in China, any scientific attempt is meaningless until the Spark Project is launched.
Anyway, this is the basis of electronic technology, which will be used in various high-tech equipment in the later period. It is better to use European power to vigorously develop it.
When the time comes, he can just use the ready-made ones.
Li Qiwei was able to predict the situation, but everyone present didn't know it.
When he made the bold statement that this problem could be solved within five years, Marconi almost jumped up with excitement.
Wilson looked shocked, "Bruce, when did you get involved in the industry? Did you license your patent to another company?"
Li Qiwei smiled: "Yes, that's right. Patent for the tungsten light bulb." Then he explained to the others.
Everyone in the room suddenly felt crazy.
It turns out that the famous wave-particle duality of light was actually raised in Li Qiwei's graduation defense.
Why is my answer only "uh uh uh".
After Li Qiwei waited for everyone to calm down, he continued: "As for the second question, Marconi, I think you are a bit pessimistic."
"Theoretically, although electromagnetic waves travel in straight lines, It spreads, but it also reflects." As he spoke, he began to draw a diagram on the white paper.
“You see, as long as a reflective layer is added to the high-altitude surface of the earth, the electromagnetic waves traveling in a straight line can be reflected and change the path.”
"Through multiple reflections between the ground and the reflective layer, electromagnetic waves can reach anywhere on the earth."
"Fortunately, I think this kind of reflective layer exists."
< br>“Due to the effect of gravity, there should be a layer of structure composed of various electrons, ions, dust, etc. in the sky above the earth.”
“This structure should act as a reflective layer to reflect electromagnetic waves. . ”
Li Qiwei certainly did not dare to speak directly about the ionosphere, because it was not proven to exist until 1924 by the British physicist Appleton.
When he deduced the reflective layer with confidence, everyone was stunned.
This is crazy. It predicts the reflection of electromagnetic waves completely theoretically.
What a brilliant idea!
Although it has not been verified, many scholars, including Marconi, firmly believe that this inference must be correct.
Ultra-long distance radio communication is absolutely feasible.
"Bruce, I have to say that your inspiration is endless and your ideas are wild and unconstrained." Rutherford said enviously.
“Your idea can even open up a new subject called meteorological science.” As a lecturer, Wilson is very experienced.
"Senior Bruce is so powerful. With just a few moves, no matter how difficult the problem is, it can be solved." Several young people worshiped him there.
Li Qiwei smiled. Even the airplane would not be invented until the year after tomorrow by the Wright brothers in the United States.
It is too early to talk about atmospheric science now.
Marconi no longer knew how to describe his mood at this time.
With a few simple words from the other party, the problem that had been bothering me for nearly a year was solved.
He gave Li Qiwei a hug excitedly, and then held his hands vigorously, "Professor Bruce, thank you, you are really my benefactor."
Li Qiwei looked slightly embarrassed, "Calm down, I'm not a professor yet." This made everyone laugh.
Marconi kept thanking him, "I am going to conduct a test this year to see if communication between the United Kingdom and Canada can be realized."
"When the time comes, I will tell you the results as soon as possible."
Then he thanked everyone one by one before returning to his seat.
With Marconi’s wonderful example as a role model, the atmosphere in the venue suddenly became lively.
Several young guys also came on stage to share their research.
Although in the eyes of big guys like Li Qiwei and Rutherford, their research is still relatively simple.
But after the previous examples, the two of them did not dare to take it lightly, and would occasionally comment or two.
This benefits the sharer a lot, and Li Qiwei’s words can even save them several years of time.
As a result, more people began to come up to share, and for a while, the warm atmosphere in the venue reached its peak.
Laue shared his research on light and various theoretical models of reflection and diffraction.
Einstein shared his research on a new method of measuring molecular size, trying to use a new theory to calculate the radius of a molecule.
Even Rutherford couldn't help but look sideways. This Jew left a deep impression on him, as if there was infinite energy contained in the other person's brain.
And this paper is very interesting and expands the application of statistical mechanics.
The idea is bold!
This young man is not simple, no wonder he is valued by Bruce.
Li Qiwei was extremely emotional. In the miracle year of 1905, Einstein published five papers, each of which was a world-class achievement.
They are the photoelectric effect, molecular size measurement, Brownian motion explanation and the existence of atoms, special relativity, and mass-energy equation.
Now, Li Qiwei has cut off the photoelectric effect and the theory of relativity. Even so, two to three, he is still no match for Einstein.
Thinking about it this way, Einstein back then was so outrageous that people couldn’t help but suspect that he was sent by aliens.
While Ridgway was thinking wildly, Einstein ended his report and won a round of applause.
Obviously everyone feels that his talent is probably not weaker than that of Ridgway, Rutherford and others.
Li Qiwei looked at the time and suggested that everyone go eat first and chat with the chemistry team, and then start again in the afternoon.
In the restaurant, Li Qiwei met Langmuir. This American young man was very cheerful and took the initiative to say hello to him.
Li Qiwei responded politely. He knew that the other party would become a doctoral student of the Nernst boss.
After graduation, he will work at Edison's General Company and be responsible for the research and development of new incandescent lamps.
Maybe the two of them may become competitors in the future.
Then, Ridgway found the person he most wanted to meet among these chemists: Fritz Haber.
If you ask, what is the most important chemical invention for the development of human society in the early 20th century, synthetic ammonia deserves the title. In the mid-19th century, animal excrement was a resource that various countries were vying for, and several wars even broke out, commonly known as guano wars.
In 1865, Spain declared war on Peru over guano. Ecuador and Bolivia also joined the war against Spain, which ended in Spain's defeat.
However, since the invention of synthetic ammonia in 1909, scientists have been able to synthesize ammonia directly from the air.
From now on, there is no need for natural nitrogen fertilizers and bird droppings. Human beings can finally get rid of the shackles of nature.
Without artificial fertilizers made from synthetic ammonia, scientists estimate that the agricultural technology at the time could only feed 4 billion people at most.
Only when people have enough food will they have various needs, and only then will there be various inventions of later generations.
Food is the first necessity of the people, and synthetic ammonia has had a profound impact on the development of world agriculture.
However, its inventor, the German chemist Haber who won the 1918 Nobel Prize in Chemistry, is a controversial figure.
People who praise him say: He is an angel, bringing harvest and joy to mankind, and a saint who makes bread from air.
Those who cursed him said: He is a devil who brings disaster, pain and death to mankind.
Because Haber served as the director of the German chemical arsenal during the first war that affected the world. He produced poisonous gases such as chlorine and mustard gas and used them in war.
This move caused nearly one million casualties and was strongly condemned by scientists from various countries.
Looking at the bald Harper with a big nose and round head in front of him, Li Qiwei could not tell his future identity as a devil.
So Li Qiwei is very confused about his attitude now.
As a native of the Qing Dynasty, he did not remember any direct harm caused by Haber himself to China.
He also wants the other party's ammonia synthesis technology to benefit China and solve the next food problem in one fell swoop.
As a large agricultural country, China’s pursuit of food is engraved in its bones.
In real history, those tragic famines, Li Qiwei will never let them happen again in this life.
He will buy a large area of land to grow food and reserve it to help China when the time comes.
At the same time, he will also bring back the ammonia synthesis technology to make preparations.
Looking at Harper now, Li Qiwei feels that it is better not to care about what has not happened yet.
Take one step at a time, maybe in this world, he can prevent the other party from going evil.
"Hello, Harper, I'm Bruce Lee."
Haber, who was thinking alone, was suddenly stunned. He did not expect that Li Qiwei would take the initiative to say hello. "Hello, Bruce, I have met you before at the Berlin Physics Annual Meeting."
"Your name is really well known, but you probably didn't notice me at the time."
Li Qiwei smiled. Haber said: "Why, do you chemists still pay attention to physics?"
Harber said: "I like to listen to lectures in other fields to inspire me. And the essence of chemistry is physics."
>
Li Qiwei felt from Haber's tone that he was an extremely confident person with a very high energy field.
"I have read the paper you wrote, and I heard that you have done a lot of research on artificial ammonia synthesis?"
"Although low-temperature and high-pressure conditions are effective, I think if there is a suitable catalyst, we can get twice the result with half the effort."
Hubber was suddenly surprised, "Bruce, aren't you a physicist, but you also know chemistry?" He put away his contempt and began to look at Li Qiwei.
As a scholar in the field of chemistry, Haber admired Li Qiwei more, but never worshiped him.
He has his own major and expertise, and thinks he is no worse than Li Qiwei.
However, the other party's words made Haber understand that he probably did study chemistry, otherwise he would not be able to say the words "low temperature and high pressure".
Li Qiwei smiled inwardly and said, although I am not a chemist, I still know that adding hydrogen to nitrogen to synthesize ammonia is just a equilibrium reaction.
“You know, I come from the Qing Dynasty. I am very concerned about food-related information and usually pay more attention to it.”
“So I have learned a few chemical terms, no matter how many more I learn, I don’t know.”
“I think that if an artificial fertilizer can be synthesized, its value will be immeasurable.”
Haber is a little confused about Li Qiwei. In fact, he has just come into contact with synthetic ammonia.
Because he was funded by several entrepreneurs, he wanted to try it.
In fact, as early as 1795, someone tried to synthesize ammonia through artificial methods, but they ultimately failed.
Harber dare not say that he is absolutely sure.
However, Li Qiwei's words still reminded him that he could consider trying several different catalysts.
"No, Bruce, your suggestion is very professional. I think I need to test it out when I go back."
Then the two began to chat. The more Harper chatted, the more shocked he became. Li Qiwei's chemical knowledge reserve was far away. Beyond his imagination.
At this moment, Harper put away his pride and was struck by Li Qiwei's genius.
He felt that if the other party changed his career to become a chemist, he would definitely be at the top level, and maybe he could easily solve the constraints of ammonia synthesis.
Soon, the halftime buffet ended, and the two branches began their special discussions.
The Young Scholars Conference lasted for three days in total.
In these three days, everyone felt the pleasure of doing academic work.
The free collision of ideas and the infinite imagination of the soul.
There is no status here, only a competition of academic level.
After all the participants went back, they wanted to vigorously promote this model.
Scholars cannot work behind closed doors. Only by communicating more can they know their own shortcomings and learn how geniuses think about problems.
Until the end of the meeting, everyone was still reluctant to leave, feeling that time passed too fast.
At noon on September 1st, everyone gathered in the hotel auditorium and prepared to return.
Millikan took Li Qiwei's hand and invited him to visit the United States no matter what, and he was responsible for the reception.
Li Qiwei smiled and nodded in agreement.
He is definitely going to the United States. He also wants to see how prosperous the United States is at this time and experience what Li Zhongtang felt five years ago.
Einstein looked deeply at Li Qiwei, his eyes said everything, and both sides showed a knowing smile at the same time.
Finally, Li Qiwei and Solvay bid farewell to all participants and promised to hold similar meetings in the future.
At the same time, he also asked Xu Qitai to follow Rutherford and Wilson and return directly to England.
He himself took Wang Luyao and Li San to the Netherlands to meet Gerald and see how the production of tungsten filament light bulbs was going.
That is the foundation of his wealth and career and cannot be lost.
Academics must be grasped, and money must be grasped, and both hands must be strong.
Please make your first order!
