Chapter 48 The Duke Pleases
As soon as Faraday asked the question, Arthur immediately felt that something was wrong.

As a high-achieving student who graduated from the History Department of the University of London, he knows almost nothing about the current progress of world science.

In order to prevent a lot of new concepts that he has not invented yet in the process of explaining the Lorenz force, this time he cleverly used the techniques of interruption and stereotyping honed in Scotland Yard and the Magistrate's Court.

Arthur touched the back of his head, pretending to be embarrassed, and said.

"Mr. Faraday, I'm sorry for mishearing you. I'm from Yorkshire, so my spoken pronunciation is not as standard as a Cockney accent. What I just said was not Lorenz (Lorenz), but Lawrence ( Lawrence)."

Faraday was surprised: "Lawrence? These two words do sound similar."

Arthur replied: "Let's not mention this for now. Are you still confused by the other things I just said when I expressed the left-hand rule?"

Faraday thought about it: "There should be nothing else, such as what kind of charge is a relatively basic concept. And your accent in other places is not so strong, I can hear it very clearly."

When Arthur heard these words, his hanging heart was finally relieved.

It doesn't matter if there are no electrons, as long as there is the concept of electric charge.

With the bottom line in his heart, Arthur's tone of voice became a lot easier.

"Mr. Faraday, you should know that Lawrence means laurels and honor.

This also represents my view of the Lawrence force, it is like an honor, it seems to exist, but in fact it does not exist.

Perhaps, it only exists in people's imagination.

That is to say, I conjecture that it may exist, but I cannot prove its existence. This may be just a nominal force. "

Faraday frowned and thought: "You mean, this so-called Lawrence force is a conjecture of yours?"

"Yes."

"Then what is your definition of it?"

Arthur saw that Faraday and the audience had been completely taken away by him, so he started to talk boldly with confidence.

"May I ask you, what is the current academic definition of current?"

Faraday replied without thinking: "Electricity was first proposed by the Italian scientist Galvani. After a long period of controversy, Mr. Benjamin Franklin discovered positive and negative charges in the 18s. Since then, after years of discussion, In the end, the academic community unified the direction of positive charge movement as the direction of current movement."

After hearing this, Arthur finally smiled and said: "As you said in your lectures and experiments just now, electricity can produce magnetism, and magnetism can also produce electricity, and you should know that there is a force between magnetism and electricity.

Therefore, when I was watching your experiment just now, I guessed that if the current is composed of charges, then in the process of magnetism generating electricity, those new charges should also be subjected to force during the movement.

Ampere's force is the force of the magnetic field on the current, and what I call the Lawrence force is the force on the moving charge in the magnetic field.

Although they are both forces on electricity, one is from a macroscopic perspective and the other is from a microscopic perspective. "

Faraday frowned when he heard Arthur's explanation. He pondered for a moment, and suddenly seemed to understand something.

He asked: "In other words, do you think Ampere's force is the resultant force of this so-called Lawrence force?"

Arthur nodded: "Exactly."

Faraday touched his forehead and said with a smile: "I have to say, this is a very interesting conjecture, and it sounds very logical.

However, as far as the current scientific research is concerned, although we know that electric charge exists, it is only a mass point in our imagination without volume and shape, which is an extremely idealized model.

No wonder you call this force the Lawrence force. Judging from the current situation, it is indeed an intangible but felt laurel and honor. "

Arthur smiled and said, "I'm sorry that I haven't brought you much substantial progress. This is just my own unrealistic guess."

As soon as Arthur finished speaking, the Red Devil beside him muttered in a low voice: "Hey! Damn it, Arthur, your guess is quite accurate."

Although the so-called Lawrence force is just a conjecture, Faraday still does not hide his appreciation for Arthur.

He smiled and patted Arthur on the shoulder: "Young man, what science needs is conjecture.

Until no one proves you wrong, then you may be right, and no one can easily deny you.

Before I got the experimental results, many people didn't believe that magnetism could produce electricity, but it did, science is such a wonderful thing.

Maybe one day in the future, the Lawrence force you talked about will become a reality?
By the way, I haven't asked for your name yet. "

Arthur bowed slightly and said, "Arthur Hastings."

"Arthur Hastings?" Faraday was stunned for a while when he heard the name, and then murmured, "I seem to have heard this name somewhere."

As soon as he finished speaking, a lady sitting not far away suddenly exclaimed: "Scotland Yard police uniform, with shiny epaulettes, his name is Arthur Hastings, and he is also very young .

my Lord!Is he, isn't he the same Sergeant Arthur who saved the poor boy's life in the Magistrate's Court? "

"The police officer who was covered in newspapers some time ago?"

"An embodiment of justice, a role model for the public, the strongest voice in Scotland Yard?"

"Oh! It might be him! Young and motivated, and yet so learned, that only such a man could convince the jury and the justice of the peace."

All of a sudden, the originally quiet venue boiled up again.

Everyone started to give a standing ovation, both as a tribute to Faraday's new discovery and as a courtesy to Arthur's vast knowledge and past experience.

Faraday saw the audience standing up and Arthur who rarely blushed but remained calm and waved back to the audience. The pioneer of electromagnetism couldn't help but said with a smile.

"Officer Arthur, who said that Lawrence represents laurels and honor? Look at the standing ovation of the public, your surname Hastings is the real laurels and honor.

Don't call it Lawrence force at all, just call it Hastings force, even if it is invisible and intangible, but as long as the public does not deny it, your name will always be there! "

Arthur heard this, surprised and said: "Is this really possible?"

"Of course." Faraday smiled and held out his hand to Arthur: "In addition, I also hope that you can allow me to quote your two rules for explanation in the paper that is about to be completed. Can you agree?"

Arthur looked at Faraday's outstretched hand, pondered for a while, and said.

"I can allow you to quote, but before that, I also want you to grant me one request."

"What request?"

Arthur said seriously: "To tell you the truth, I actually wanted to listen to a chemistry lecture today. But..."

Faraday laughed loudly when he heard the words: "It turns out that you are for this matter, I am more confident in chemistry than in electromagnetism.

If you want to hear about this, you can come to me anytime.If I am not here, then I must be in the laboratories of the Royal Society.

Oh, by the way, I can go to the president and ask you for a pass to the Royal Society, so that you can enter and leave the academy at any time. "

When Faraday said this, he just wanted to turn his head to find the president.

Unexpectedly, as soon as he turned around, he saw a servant also wearing a dark black suit running towards Arthur.

The servant bowed slightly, and said to Arthur, "Mr. Hastings, the Duke of Sussex, President of the Royal Society, please."
