Shadow of great britain

As soon as Faraday's question came out, Arthur immediately felt something was wrong.

As a top student who graduated from the History Department of the University of London, he knows almost nothing about the current scientific progress in the world.

In order to prevent him from introducing a lot of new concepts that have not been invented yet in the process of explaining the Lorentz force, this time he cleverly used the interruption and cliché skills honed in Scotland Yard and the magistrates' court.

Arthur rubbed the back of his head, pretending to be embarrassed, and he spoke.

"Mr. Faraday, I'm sorry you misheard. I'm from Yorkshire, so my spoken pronunciation is not as standard as a London accent. What I just said was actually not 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 explained the left-hand rule?"

Faraday thought about it for a moment: "There should be no other things, such as electric charge and the like. They are all relatively basic concepts. And your accent in other places is not that strong. I can hear you very clearly."

When Arthur heard these words, his hanging heart finally relaxed.

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

With confidence in his heart, Arthur's tone of voice became much more relaxed.

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

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

Perhaps, it only exists in people's imagination.

In other words, I speculate that it may exist, but I cannot prove that it exists. It may be a nominal force. "

Faraday frowned and thought: "Are you saying that this so-called Lawrence force is just a conjecture of yours?"

"That's right."

"So what's your definition of it?"

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

"Excuse me, what is the current academic definition of electric current?"

Faraday replied without thinking: "The electric current was first proposed by the Italian scientist Galvani. After a long controversy, Mr. Benjamin Franklin discovered positive and negative charges in the 1750s. After many years of discussion since then, In the end, the academic community unanimously defined the direction of positive charge directional movement as the direction of current movement."

When Arthur heard this, he finally smiled and said: "As you said in your lecture and experiment 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 electric charges, then in the process of magnetic electricity generation, those newly born electric charges should also experience forces during their movement.

Ampere's force is the force exerted by a magnetic field on an electric current, while what I call Lawrence's force is the force exerted on moving charges in a magnetic field.

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

Faraday frowned when he heard Arthur's explanation. He thought 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: "That's right."

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

However, as far as current scientific research is concerned, although we know that electric charge exists, it is only a particle in our imagination that has mass but no volume and shape. It is an extremely idealized model.

No wonder you call this force the Lawrence force. Judging from the current situation, it is indeed a laurel and honor that is intangible but feels to exist. "

Arthur smiled and said: "I'm sorry that I haven't been able to bring you much substantial progress. This is just my personal unrealistic guess."

As soon as Arthur finished speaking, the red devil beside him muttered: "Hey! Damn it, Arthur, your guess is quite accurate."

Although the so-called Lawrence force is just a conjecture, Faraday still did 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 are 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 talk 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 moment when he heard the name, and then muttered: "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, wearing shiny epaulettes, his name is Arthur Hastings, and he is also very young. .

my Lord! He, he couldn't be the officer Arthur who saved the poor child's life in the magistrate's court, right? "

"The police officer who was covered in newspapers a while ago?"

"The personification of justice, the public role model, the strongest voice of Scotland Yard?"

"Oh! It might really be him! He is young, motivated, and so knowledgeable. Only such a person can convince the jury and the magistrate."

Suddenly, the originally quiet venue became excited again.

Everyone began to stand up and applaud, not only to pay tribute to Faraday's new discovery, but also to pay tribute to Arthur's rich knowledge and past experience.

Faraday saw the audience standing on their feet and Arthur, who rarely blushed but remained calm and waved back to the audience. The founder of electromagnetism couldn't help but smile.

"Officer Arthur, who said Lawrence represents laurels and honors? Look at the public standing and applauding. Your surname, Hastings, is the real laurels and honors.

Just don't call it Lawrence Force, just call it Hastings Force. Even if it is invisible and intangible, as long as the public doesn't deny it, your name will always be there! "

Arthur heard this and said in surprise: "Is this really okay?"

"Of course." Faraday smiled and stretched out his hand to Arthur: "In addition, I also hope that you can allow me to quote your two rules to explain in the paper that is about to be completed. I don't know if you Can you agree?"

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

"I can agree to your citation, but before that I also hope you can grant me a request."

"What request?"

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

Faraday laughed loudly when he heard this: "So you are here for this, chemistry, I am more confident than electromagnetism.

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

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

When Faraday said this, he was about to turn around to find the president.

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

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