Chapter 46 Who in the world doesn’t know who you are?
When the three big guys including Baron Rayleigh acquiesced, the controversy over quantum theory finally ended.
As the principle of the photoelectric effect was clearly displayed on the blackboard, all physicists present understood that the world of physics was about to change.
A brand new physical theory, its significance is immeasurable.
The professors at Oxford University were still downcast at first, but they quickly cheered up.
"Oh, my God, what kind of genius were we arguing with before? It's a bit shameful to think about it now."
"It's really hard to imagine that he is only a 20-year-old undergraduate. Compared with Newton, it’s not much different.”
“The influence is still far behind. After all, both quantum theory and the photoelectric effect work in the microscopic world and currently have little impact on the real world. Big.”
“In any case, a new theory is a great progress in physics, and we should learn it.”
It’s unfortunate that it doesn’t refute quantum theory. Vice President Lucas, as professors, they are now able to come into contact with a brand new physical theory, and their excitement is indescribable.
Moreover, maybe you can use this to open a few more courses and earn more tuition. It is said that Newton invented calculus in order to increase the revenue of the college, because if you fail the exam, you will have to pay for a make-up exam.
Seeing that no one stopped asking questions, Lord Kelvin was about to declare the debate over.
There is really too much content in this meeting, especially the final photoelectric effect, which needs to be digested carefully.
Suddenly, Ridgway made a request, "Lord, I have something to say about the photoelectric effect."
"Oh?" Lord Kelvin was stunned, and then said: "Bruce, please Feel free, I think everyone here would love to hear you talk.”
After saying that, it caused a burst of laughter.
Li Qiwei touched his nose awkwardly, and then said seriously: "The last thing I want to say is actually an initiative."
"As we all know, physics has been accompanied by theory since its inception. Mutual verification with experiments."
"Physics masters in the past were often both proposers of theories and verifiers of experiments."
"However, with the continuous development of physics, physics Learning becomes more and more in-depth and professional. Even if you are a giant, it is difficult to take care of both.”
"And physics now tends to pay more attention to theories and phenomena, while ignoring experiments and prop design."
"Newton's law of universal gravitation and Maxwell's electromagnetic equations are all great achievements of pure theory."< br>
“In comparison, the experimental verification of these theories is often more like a supplement.”
“In other words, physicists who engage in experiments are far less effective than those who engage in theory. Eye-catching."
"I think that's unreasonable."
"For example, my senior brother Wilson, although he is not as good as me in theory, when it comes to designing instruments and designing experiments, I can't keep up with him."
At this point, everyone knows what Li Qiwei is going to say. , couldn't help but be impressed by his big heart.
Wilson looked at him in disbelief, and his heart was filled with emotion.
Li Qiwei continued: "Therefore, I would like to propose that future physical research can be divided into theoretical physics and experimental physics."
"Theoretical physics school pays attention to exploring the natural world theoretically Unknown structures, interactions, and motions of matter, or discover new phenomena ”
"The experimental physical school explores the material world and natural laws through experiments, and at the same time verifies the correctness of theories and phenomena."
"The two have the same status and are both important components of physics."
After saying that, the audience burst into applause once again, especially those teachers who themselves taught experimental classes in schools, and they agreed with it from the bottom of their hearts.
Yes, people who do physical experiments are often considered to have no strength and can only do some craftsmanship.
But now, a theoretical physicist who may be the most genius in the world has taken the initiative to speak out for the experimentalists. How can we not be moved?
Wilson even clapped his palms red. He decided to have a few drinks with Li Qiwei after he went back.
Li Qiwei looked at everyone's expressions and was very emotional.
He moved out the physical divisions of later generations twenty or thirty years in advance in order to accelerate the development of physics.
In this era, there are actually not as many laboratories in universities as imagined, and more are privately owned laboratories.
When those big guys are happy, they do some experiments, and when they are unhappy, they go out and have fun. They do not regard experiments as a physical science. And because communication is inconvenient (compared to later generations), often after a theory is proposed, no one can or wants to prove it with experiments immediately.
This results in slow progress in physics.
Historically, Einstein proposed a theoretical proof of the photoelectric effect in 1905, but it was not experimentally proven until 1916 by American physicist Millikan.
Of course there are many reasons for this, but the slow development caused by the lack of attention to experiments is definitely an important factor.
So, he added: "In order to show the importance I attach to experimental physics, I decided that I will not participate in the experimental demonstration of the photoelectric effect."
"If you can design experiments to prove it, then the corresponding results and honors belong to you."
Wow!
This time the venue was completely shocked.
Everyone was shocked by Li Qiwei's courage.
You can understand the weight of this sentence by analogy.
Maxwell theoretically predicted the existence of electromagnetic waves in 1865, and Hertz experimentally proved the existence of electromagnetic waves in 1888, thus becoming famous and becoming a top physicist.
It is no exaggeration to say that if a great theory can be verified, then the result itself is also great.
And now, Li Qiwei has announced that he will not participate in the experiment.
How can everyone not be surprised.
However, think about it, he has two major theoretical achievements: quantum theory (after the meeting, Ridgway decided not to call it quantum mechanics for the time being, waiting for improvement.) and the photoelectric effect.
Li Qiwei no longer needs additional honors. He is now the top physicist in the world, and can be as famous as Roentgen and other big names.
From now on, at least in the world of physics, Li Qiwei is worthy of saying: There is no one in the world who does not recognize you.
Of course, because he is still too young now, his reputation will be slightly lower, but these will all happen in the future.
But it’s different for others.
Millikan's eyes in the audience were blazing. He was going to start designing experiments immediately after returning to the United States.
Quantum theory and the photoelectric effect will definitely become the mainstream topics in the physics community in the future. As long as he can prove it, his professorship will be absolutely stable.
Unfortunately, even Li Qiwei himself does not know whether his butterfly wings will cause historical changes.
Soon, today's meeting ended in a warm atmosphere.
Li Qiwei looked at Plank and showed a relieved smile, and then the two of them walked off the stage together.
After shaking hands and getting to know the big guys below, Li Qiwei finally calmed down.
The high-intensity debate just now consumed almost all his energy, and his brain was running wildly and was about to explode.
Even a time traveler feels overwhelming and thrilling when facing such a group of top human beings.
Of course, if Li Qiwei does not practice martial ethics and reveals too many secrets, there will be no pressure. But I'm afraid he will be taken away by the British military on the spot.
Next, everyone went to have afternoon tea and rest for a while, and then it was a normal academic exchange meeting.
After all, the Royal Society must not be the only one to hold such a large-scale meeting.
Rather, we will take this good opportunity to allow the world's top physicists to exchange ideas, discuss academic issues, and enhance Britain's scientific influence.
In the restaurant, in addition to the smell of food, there is also the fragrance of knowledge in the air, which makes people feel relaxed and happy. Li Qiwei is chatting and laughing with all the big guys there.
At this time, Lord Kelvin walked towards him with a smile on his face, and there was an old man who looked about 60 years old beside him, "Bruce, I will introduce you to a friend."
The old man said: "Hello, Mr. Bruce, I am Ernest Solvay."
Thank you all new and old book friends for your recommendation votes.
