Li Fuji, this is a name that has almost been forgotten by history, and it is also a name that is destined to be remembered. This man, who was a fellow villager with Sun Yuanqi, graduated from Nanyang College in July 1901 and was immediately sent by the school to study abroad

Europe, studied mechanical engineering at Finsbury College, University of London. In 1906 he entered the Royal University of Bonn, where he studied under Kai

Also accompanied by Zeng Zongjian and Hu Zhenping, who studied politics, and Zhao Xingchang, who studied business. We started with King's College

English, and then separated. I went to Finsbury College to study mechanical engineering and then to London as a mechanical engineer

After a year of internship, he is now graduating from the University of London to study mechanical engineering. I just saw the school post

The poster says that you will have an academic report in the near future. I inquired with the school and the Royal Society and found out your address. this

I'm sorry to interrupt your work! “

Sun Yuanqi didn't care, and waved his hand: It's okay, it's okay. I'm also busy, and I don't have anything serious. That, you

Do you plan to continue your education?

Li Fu nodded: Yes, I think there is still a lot to learn. I wanted to petition for a two-year extension to stay in Europe

Learn. Now I am waiting for the news of Mr. Sheng, the superintendent of Nanyang College, and Mr. Zhang, who has been promoted and the general manager. I don't know how they will reply

This! “

Sun Yuanqi blinked: Then which piece of mechanical engineering do you plan to continue to study? Li Fuji was a little embarrassed: Because I haven't gotten the exact news yet, I haven't thought about it so much at this time. "Can I make a suggestion? Sun Yuanqi asked tentatively.

Li Fuji hurriedly said: Mr. Sun, you are a famous material scientist, and it is my honor to be able to get your guidance! Please speak

Please speak. “

Sun Yuanqi explained in a soft voice: We Chinese have always liked to say 'apply what we have learned', especially now, when the country is in decline

The people are withering, and what we learn should pay more attention to practicality. I didn't pay much attention to this before, but now I realize that it is

In the change. (Remember, you'll learn from my experience and focus on the parts of mechanical engineering that are most valuable to the country earlier.)

In my opinion, the biggest gap between China and foreign countries in mechanical engineering is engine design and manufacturing. To know

, the engine is the heart of the ship, and it has a lot to do with it. And our country is the strong ship and cannon of Britain, France and other powers

If we can't make a breakthrough in this area, then our vast sea frontier will eventually belong to others. So

, I suggest you learn the design and manufacture of engines. “

Seeing that Li Fuji was thinking silently, Sun Yuanqi said again: If you learn engines and are willing to come to us after graduation

Working at the University of the World, we pay for your study and living expenses in Europe! “

Li Fu thought about it for a long time, but he didn't agree immediately, but only said that he would think about it when he went back.

A few days later, Li Fuji visited again and gave a mixed answer to Sun Yuanqi: he was happy that he agreed

Learning engines can provide some help for the future development of China's machinery industry and weapons industry

Nanyang College wrote to him, saying that he was very talented and ambitious to learn, and that he should develop his talents for a long semester in order to prepare for his return to China

It was agreed to extend it until June 1907 with an annual contribution of £180. In other words, after Li Fuji graduated, it was not very good

I can work at Keiyo University.

With a slightly lost mood, Sun Yuanqi ushered in November 30. On this day, the Royal Society picks up trucks in London

Diri's BurlingHe held a grand award ceremony and decided to co-opt Sun Yuanqi as the British Crown

Foreign member of the Society.

After receiving the Materialley Prize and the David Prize. Sun Yuanqi began his speech, and the topic was very simple, just called: Anti-Object

Quality.

The speech began with the discovery of the cosmic striking line: last year, Professor Rutherford discovered when he used the free room to observe the percussion of the body,

Even if you carefully remove all the sources of the put-away. In an electroscope, there are still about ten per second per cubic centimeter

Counterions are constantly generated. If the electroscope is completely shielded with iron and lead, the ion production can be almost reduced

Less 310. Rutherford published a paper on this purpose, suggesting that it might be some kind of penetrating force, similar to a Y-body attack

Some kind of radial blow of the wire strikes into the electroscope from the outside. Thus stimulating the secondary letting go of the attack.

In July and August of this year, I met Professor Rutherford in Canada, and he mentioned this issue to me. My opinion is

This kind of body attack line comes from the universe, passes through the atmosphere and then comes to the earth, and then influences the experiment, producing the ionization phenomenon of the free cell

。 Studying this cosmic body line can give us an in-depth understanding of the composition of the universe and even how it came to be

。 “

In the history of modern exhibitions, the study of the cosmic body striking line occupies a certain position, and many new particles are the first to appear

Discovered in the cosmic body strike line. For example, positrons, μ mesons, π mesons, etc. Before the advent of high-energy accelerators,

People can only rely on natural sources for research, and the cosmic body line is an ideal object of observation, and it has high-energy stars

It is easy to observe due to its low intensity. Therefore, once it was discovered, it became the object of people's research.

What Sun Yuanqi is saying now is to guide British scientists to give up the study of high-energy accelerators and instead seriously observe the cosmic physical attack

line, silently contributing to the development of science.

Turn. Sun Yuanqi also promoted his concept of antimatter: "Now, we have found that atoms are at least composed of electrons,

Neutrons are composed of two types of particles. Among them, the electrons are negatively charged, and the neutrons are not charged, that is, there must be one more in the atom

The particles have a corresponding positive charge, which makes the entire atom stable. At this time, some people may think. world

Is there such a substance, positively charged, another particle negatively charged, plus an anti-neutron structure?

What about it?

At the end of last year, one of our Chinese students named Zhang Yihui was the first to put forward this idea. I thought about it for a long time

For a long time, he believed that such a substance should exist in the universe. It is the opposite of the matter that exists on our earth, so it can be called it

'Antimatter'. Can matter and antimatter coexist? This is a problem. I think the biggest possibility is annihilation.

That is, positive and negative neutralization, and the prime star transforms into a huge energy star. Moreover, energy stars should follow what I wrote in my book The Photoelectric Effect: From Phenomena

to the essence of the mass-energy equation mentioned in the article"

This is pure empty talk, and the orthodox scientists sitting in the audience have already begun to move 31 times when they hear this, if it weren't for England

The custom requires them to be gentlemanly at all times, and it is estimated that they are about to leave the field or ask a rebuttal.

Sun Yuanqi finally threw out his bait: Combining the above two conjectures, we can deduce that if the universe exists

matter, then there should be a certain amount of antiparticles in the cosmic body strike line that are contrary to the known particles of the earth. This is a corollary

Can this be proved experimentally? I think it's totally possible! To this end, on the ship from Boston to London,

I designed an experimental protocol. “

The scheme mentioned by Sun Yuanqi is the device that Anderson discovered in 1932 about the positron: first place the cloud chamber in a magnetic field,

When the particles enter the cloud chamber, they will be divided according to their electrified nature: several metal plates are installed in the cloud chamber to let the grains

The seed passes through the metal plate, which in turn distinguishes its energy star. After a long period of observation of the star, one can be found in the photo

A peculiar trail that is similar to the path of an electron, but in the opposite direction. This is the positron.

After Sun Yuanqi finished speaking, there was silence in the audience

In the eyes of these scientists, Sun Yuanqi is simply talking nonsense, and what he says is useless. But to refute, here

Speeches full of conjectures that cannot be proven with existing knowledge. But fortunately, Sun Yuanqi gave a can

Quickly validated protocol: If the experiment is not successful, doesn't that mean he's talking nonsense? If you can pierce this with your own hands

The delusion of a young materialist, known as the greatest young materialist at the beginning of this century, embarrassed him, and it was also very dignified to think about it

Son's business, right?

As a result, many material scientists in the audience were eager to try, and they only waited for the ceremony to return to the laboratory to prepare.
