1900: A physics genius wandering around Europe

Chapter 86 Laboratory Work
Time enters June.

After Li Qiwei read Luo Fuyu's invitation in the morning, he immediately had an idea in his mind.

After he came to the laboratory, he began his doctoral research.

Although he had various theories in his mind, they were all acquired through rote learning and were far less profound than those gained through personal practice.

Besides, if he published various papers without any experimental data, he would probably be taken away and secretly investigated at the first moment.

Physical theories can also be explained by talent, after all, there are bugs like Ramanujan in the world.

However, without detailed and accurate data support, it is impossible to achieve results in nuclear structure research.

He had to do the experiment himself to dispel other people's doubts.

Moreover, Li Qiwei also has his own ambitions. He wants to improve his own strength in this way.

In his previous life, he was a Ph.D. from China University of Science and Technology. He was a prodigy among ordinary people, but he was just an ordinary person among the prodigies.

So in this life, on the eve of the great explosion of physics, he will compete with the big names in physics, train himself, and break his own limits.

Immerse yourself in this research atmosphere, relying not on prophets but on your own talents.

Later theories are basically based on the foundation of relativity and quantum mechanics.

There are breakthroughs, but nothing earth-shaking.

If in the future he can unify the four fundamental forces, discover dark matter and dark energy, and explain the origin of the universe, then he probably wouldn't even deserve the Nobel Prize.

Thinking of this, Li Qiwei's blood boiled and he rolled up his sleeves to start assembling the equipment.

The sad thing is that it took him a long time to install the simple magnetic field acceleration equipment.

In later life, he was used to using all kinds of high-end equipment, and now that he had to assemble and build them by himself, he realized how difficult it was.

At this time, Wilson came over and saw Li Qiwei busying around. He immediately laughed and said, "Oh, Bruce, I finally see that you are not good at something sometimes, hahahaha."

After saying that, he took the initiative to step forward to help, and after a few clicks, he got the instrument set up and adjusted the magnetic field. Everything was normal.

Li Qiwei sighed, it turns out that every Nobel Prize winner should not be underestimated.

Although the cloud chamber is simple, the person who was the first to think of it is definitely not simple.

When evaluating the achievements of our predecessors, we must substitute the objective conditions at the time, and not understand it based on the difficulty of later generations.

Li Qiwei smiled and said, "Thank you so much, Wilson. To show my sincerity, I would like to treat you to a big meal."

"Feast?" Wilson was stunned, then he understood, "Oh, Bruce, are you going to cook Chinese food yourself?"

"Haha, my cooking skills are not that good. This time our Chinese master chef will cook for you. You are in for a treat." Li Qiwei thought to himself that the chef brought by Luo Fuyu must be good.

"Oh my god, that's great. Only Chinese food can surpass British food in this world."

Li Qiwei held back his laughter. There are delicious foods in the UK?
There are two shortest things in the world: American history and British recipes.

Wilson had never had good food in his life, so it was understandable, "Bruce, when are we going to try the chef's cooking?"

"On October 10th, I'll take you to a place you'd never imagine."

"Great! I'm really looking forward to the legendary Chinese cuisine."

Li Qiwei looked at Wilson's envious expression and smiled faintly. Yes, this was his plan.

He planned to bring Wilson with him, and when the time came, even if Luo Fuyu had the guts, he would not dare to tamper with the drinks.

As for the five hundred swordsmen and axemen hidden in the room?

If Wilson was accidentally hurt and it became a diplomatic incident, given the current situation of the Qing Dynasty, Luo Fuyu would have to wait for his entire family to be exiled to Ningguta.

Therefore, as long as the other party is a normal person, Li Qiwei will be absolutely safe and sound. He can go there and come back as he pleases, and have a good meal at the same time.

You can say that someone who can become ambassador to the UK is corrupt and opportunistic, but you must not say that he is stupid.

Finally, he would bring Li San along as a double insurance.

The Qing Dynasty's embassy in the UK was in the city center, which was not a good place to carry out conspiracies.

After finishing his preparations for the banquet, Li Qiwei continued his research and experiments.

His goal was to replicate the alpha particle scattering experiment (gold foil experiment).

The principle of the whole experimental process is very simple. The alpha particles are bound by a magnetic field to form a straight line, which bombards a gold foil with a thickness of microns. Then the deflection angles of the alpha particles in various directions after the action are measured.

Most alpha particles penetrate the gold foil directly, so the deflection is very small.

About 1/8000 of the alpha particles have a deflection angle greater than 90°.

There is even scattering with a deflection angle greater than 150°, which is called large-angle scattering.

These alpha particles with large deflection angles are because they collide with the nuclei of gold atoms, interacting with each other and changing the angle.

These phenomena are obviously inconsistent with the predictions of Thomson's atomic pudding model.

Therefore, the alpha particle scattering experiment proved that there is indeed a positively charged core inside the atom, rather than the positive charge being evenly distributed throughout the atom.

The instruments used in the experiment include: alpha particle source, magnetic field control instrument, gold foil, fluorescent screen (for observing scattered alpha particles), and sealed chamber.

Li Qiwei started from the basics and began to complete his experiment bit by bit.

This was also due to his previous internship at Cavendish, otherwise he might not have been able to do it so quickly, as building the equipment by himself is not easy.

When he was working very hard, suddenly, his colleague in the laboratory called him and said that someone outside wanted to see him.

Li Qiwei wondered who would come to see him, and after walking out of the laboratory, he saw a middle-aged man in his forties. There were two people following him, and there was a large package next to him.

Li Qiwei asked: "Hello, I'm Bruce Lee, who are you?"

The middle-aged man immediately stepped forward to shake hands and replied, "Hello, Dr. Bruce. I am Trevor, the plenipotentiary representative of Zeiss in the UK and currently the head of the London branch."

"I came here today to give you a projector."

"Ever since I reported your needs, the company has treated this matter as the most urgent task."

“Luckily we had made similar products before, so it was completed quickly.”

"And they use the company's most advanced lenses, which provide better projection effects and are more convenient to use."

As he said that, Trevor had someone carry the projector into the laboratory.

Li Qiwei suddenly realized that he almost forgot about the projector.

I didn’t expect that Zeiss was so strong that the prototype was produced in less than a month.

He quickly called Wilson and others to come out to receive it, and then took Trevor outside to discuss in detail.

After hearing the explanation from Trevor's two assistants, everyone in the laboratory realized that there was such a useful thing.

The key was invented by the genius in the laboratory, Bruce.

In the future, when they hold meetings to discuss presentations, it will be more convenient and efficient.

For a moment, Wilson couldn't wait to open the package, asked his assistant to assemble it, and then began to learn how to use it under the other party's training.

In the Eagle Bar, Li Qiwei and Trevor sat opposite each other.

"Mr. Trevor, thank you very much for delivering the items personally. I'll give you the money."

"Haha, Dr. Bruce, you are joking. This is a gift from Zeiss. How can I ask for money?"

Li Qiwei smiled and thanked him. "I've heard that German companies have always maintained a rigorous and extreme attitude. I'm sure the quality of the projector must be very good."

Trevor was slightly stunned, "Dr. Bruce, are you also interested in the enterprise?"

"Oh? Didn't Gerard tell you that I was working with his Philips?"

"I licensed him my patent for the tungsten filament light bulb."

Trevor smiled bitterly, "That guy actually dared to lie to me. It turns out that he has such a close relationship with you."

"Dr. Bruce, we at Zeiss also very much hope to cooperate with you."

After privately investigating Li Qiwei's background, Trevor realized that the young man in front of him should not be underestimated.

In addition to his own strength, the network of relationships behind him is also a huge asset, especially for a high-tech company like Zeiss.

Li Qiwei said: "Mr. Trevor, you are too polite. Of course I am willing to cooperate with your company."

"In fact, I am very interested in many German companies, such as Krupp, Siemens, Mercedes-Benz, Bosch, etc."

Trevor was shocked. He didn't expect that Li Qiwei knew so much. These were all famous companies in Germany.

"Dr. Bruce, if you are willing, I can introduce you to the contacts of these companies."

"We in Germany very much welcome outstanding physicists like you."

Trevor revealed his profound background in just one sentence. It seems that the British head of Zeiss is not a simple person.

"It is really my honor. I think pure physics research is interesting, but if it can be transformed into practical products that benefit mankind, it will be more meaningful."

"So I often think about some patents, hoping to have the opportunity to cooperate with enterprises to promote the development of physics."

“The power of enterprises can never be ignored.”

Trevor's eyes lit up. The young physicist in front of him was different from any he had ever seen.

There is no such condescending attitude that thinks that those who run businesses are all engaged in applied technology and are not up to the standard.

"That's very well said, Dr. Bruce. It's a pleasure to meet you. I believe our future cooperation will be very smooth."

The two toasted and drank it down.

After sending Trevor away, Li Qiwei was in a good mood. He finally found a breakthrough to open up the situation.

Regarding the industrial system, he was unwilling to trouble Planck, Thomson and others because that would mean he would owe them too many favors.

Gerrard is too busy now to help him.

The appearance of Trevor gave Li Qiwei hope.

With the other party as the center, he will get to know the heads of major companies in Britain, France and Germany.

By then, his Chinese employee training program will be able to begin.

These future industrial giants are still in the growth stage and are in need of all kinds of people. This is a good opportunity for him to make plans.

Over the next few days, Li Qiwei worked as usual.

The emergence of projectors has completely changed the current presentation problems in academic exchanges and has been well received by many scholars.

And he also has to keep the appointment.
