Chapter 42 Facing the Big Boss
When Li Qiwei said, "Everything in the world is [quantum], and existing physics is only an approximation," everyone was shocked by his remarks.
The professor who asked the question was even speechless, his brain was in chaos.
Although this answer solved his doubts, it gave him new fears.
It turns out that physics has been developed for more than three hundred years, but it is still not the most correct truth, but a crude weapon used by humans to describe the world.
This. This is simply more exaggerated than a fantasy.
Especially the last sentence, "This is the Creator's mercy for mankind", made the Oxford professor stunned.
Since Copernicus proposed the heliocentric theory and Galileo established the modern scientific system, Europeans have long been freed from the shackles of theology.
The physical system established by countless geniuses who have spent their whole lives working hard proves that humans can understand and transform the world without God.
And now, a genius in the field of physics has publicly said that their theory is wrong and that it is only useful because of the mercy of the Creator.
This is simply unacceptable.
Even the big guys present looked at him slightly, obviously shocked by Li Qiwei's remarks. There were whispers everywhere in the venue.
If Li Qiwei knew their inner thoughts, he would definitely be speechless.
He just feels that the truth of the universe cannot be fully understood, so there is nothing wrong with approximation, as long as it can be used.
The West also believes in God, so he follows the local customs and says, "The Creator has mercy on mankind."
I didn't expect it would cause such a big response.
In fact, if he had a little knowledge of European history and the agnosticism and agnosticism of philosophy, he would not have said these words.
In the final analysis, it is still the cultural difference between China and the West.
But fortunately, Lord Kelvin relied on his experienced experience to take control of the entire scene immediately.
“Quiet! Quiet!”
"Bruce Lee is from the Qing Dynasty, where we have different beliefs, so please understand and respect each other."
"Here today, we only discuss scientific issues. You can think that the Creator is a higher level "
As expected, everyone felt much better after hearing Lord Kelvin's explanation, and because Li Qiwei was so young, they no longer struggled with this.
At this moment, Li Qiwei finally understood what the problem was, and he cast a grateful look at Lord Kelvin.
The challenge continues!
Li Qiwei defeated several professors one after another, but he was not complacent and relaxed because the real boss had not yet taken action!
For a while, no one raised their hands to ask questions.
Because even several professors at Oxford University could not refute the [quantum] theory, everyone present was a little bit murmuring in their hearts.
Just when Lord Kelvin wanted to speak out and remind everyone to continue asking questions, the calm was broken.
A person in front of the venue raised his hand and slowly stood up. Li Qiwei looked closely and saw that it was Madame Curie.
The 33-year-old Marie Curie still has her charm at the moment. Although she is a scientist, she has an aura of agility and is not the stereotype she imagined.
No wonder the entire physics circle loves this female scholar. Just like a flower appearing in the steel jungle, it is of course very precious.
She smiled slightly and said: "Bruce, I have wanted to see you for a long time. I am very lucky to meet you in person today."
Li Qiwei quickly expressed his thanks and responded to the boss.
Madame Curie said: "I admit that your [quantum] concept is correct, but what does 'mechanics' mean in [quantum mechanics] in your paper?"
"As you said before, [Quantum] is a basic physical property that only plays a dominant role in the microscopic world."
"So [Quantum Mechanics] is the study of the force of microscopic particles? But this kind of Is the force different from the force of Newtonian mechanics? "
"How can there be other forces besides gravity and electromagnetic force?" "So, even if the [quantum] concept is correct, it seems to be nothing. These forces can be explained by classical mechanics. ”
“Classical mechanics can be used for microscopic individual quanta, and classical mechanics can still be used for the whole composed of countless quanta.”
Wow!
As soon as the experts took action, they would know if there was any. Everyone was impressed by Mrs. Curie's question and nodded in agreement frequently.
Even Li Qiwei himself was trembling. The angle of this question was too tricky. As expected, the big guys were so scary.
Li Qiwei only briefly mentioned [quantum mechanics] in his paper at that time, and did not elaborate on the details in depth.
It is because the explanation here is very complicated, and the factors of the times have to be taken into consideration.
Historically, the real [quantum mechanics] was proposed after 1927 when it was jointly perfected by Dirac, Schrödinger, Heisenberg and others.
It contains three key points: quantization, uncertainty principle, and wave-particle duality.
[Quantum Mechanics] It is believed that microscopic particles have dual properties of waves and particles. Their speed and position cannot be accurately measured at the same time, and they can only exist in the form of probability.
To put it simply, Newtonian mechanics studies the macroscopic, and [Quantum Mechanics] studies the microscopic. (Note: This statement is not rigorous)
Today, Li Qiwei only proposed quantization alone and did not involve the latter two concepts, so [quantum mechanics] appears to be very thin.
More importantly, the consensus among all physicists at this moment is that there are only two forces in the world: gravity and electromagnetism.
The other two of the four fundamental forces, the strong and the weak, would not be discovered until decades later.
Therefore, the current dilemma is that Li Qiwei cannot perfectly explain Marie Curie's problem using the existing knowledge.
For a while, everyone in the venue saw that Li Qiwei was silent and thinking quietly.
Glanck next to him was also worried about his disciple. He didn't know how to solve this problem and couldn't help at all.
Time passed by, and just when Lord Kelvin was about to come out to smooth things over, Ridgway finally spoke, and he said slowly:
“Thank you for your question, Madame Curie, this is a very good question. "
"First of all, what I call [quantum mechanics] is no different from the force in Newtonian mechanics."
"However, the two theories study force from different angles."
“Recently, I was doing research on electrons in the Cavendish Laboratory, and I discovered some strange phenomena.”
"Some of the movements of electrons do not seem to be explained by classical mechanics or electromagnetic theory."
"So as you said, it is not feasible to use classical mechanics to explain a single quantum."
“And if you think about it using the concept of [quantum], you will get very different results.”
“Therefore, my [quantum mechanics] is mainly to study the behavior of microscopic particles. Macroscopically speaking, Newtonian mechanics is sufficiently complete for the time being. "
"Of course [quantum mechanics] is the theoretical framework, and more results are needed to fill it in. The [quantum] concept is the core of my paper."
After Li Qiwei finished speaking, Wilson's eyes in the audience were as wide as bells. He looked at Rutherford next to him with a calm expression.
So Wilson wondered: I am also a member of the project team, why don’t I know about this problem.
It turns out that Li Qiwei had a private discussion with Rutherford, and both of them believed that there was something wrong with the jujube cake model of their mentor Thomson.
Rutherford believed that there was a problem with the model and that he could just change to a classical mechanics model; but Ridgway firmly believed that the classical theory could not explain it.
Due to immaturity, the two have not yet reported to Thomson, so Wilson does not know.
Poor old Wei was hit again.
