A Century of Family: Immortality Since the Republic of China

Naturally, it is rare for him to be a hands-off shopkeeper.

After a simple wash and breakfast, Jiang Chen went out.

on the street.

Even the street vendors are starting to discuss the stock market.

You can hear stocks and related information almost everywhere. In the foggy capital at this time, it seems that if you can't talk about stocks a few words, you feel as if you can't keep up with the times.

And listening to these voices, Jiang Chen's expression couldn't help but concentrate.

Especially at this moment, he became more solemn.

"Sir, how about I recommend a stock to you?"

"Sorry, I'm not interested in this!"

"Ah, that's a pity, you have to know that our stock market is a bull market now!"

"That's a pity."

Jiang Chen opened his mouth and refused a stock recommended by the shoe polisher.

The persistent figure stood up.

Smith next to him quickly followed.

"Let's start clearing the stock in your hands immediately!"

Jiang Chen spoke without any hesitation.

As a descendant, he is very clear about what this situation represents now, it means that the entire market is already at its peak, and if it doesn't go away, I'm afraid it won't go away.

No one in the world is a fool.

If the initial push was him, then the subsequent push was definitely not him.

To be able to reach this point, it is obvious that some capital has started.

As for their purpose, of course, is to harvest.

Jiang Chen had no doubts about the next result.

Faced with such a result, there is almost no need to say how to choose.

"understand!"

Although Smith had some doubts, he would absolutely obey Jiang Chen's orders.

Smith quickly dealt with it.

Jiang Chen returned to his hotel.

Produced in the early nineteenth century, the British Industrial Revolution promoted the development of productive forces and brought human society into the industrial age.The first luxury hotel villa in France.

From the beginning of the 20th century to World War II, the first commercial hotel appeared in the United States. Its location was in the center of the city or beside the highway. At this time, the hotel could provide comfortable, convenient and clean services, with safety as the service tenet and reasonable price.

At this time, John Bull's house naturally had a hotel, and Jiang Chen lived in a hotel called Victoria.

The people who come and go are almost either chaebols or nobles.

Just came back, he was not in a hurry to go upstairs, he found a seat in the lobby of the hotel and sat down.

It's just that he just did it.

A rushing figure rushed over.

Then he ignored Jiang Chen, took out a pen and paper from his bag, and quickly began to scribble on the paper.

"Equivalent principle: divided into weak equivalence principle and strong equivalence principle. Weak equivalence principle holds that the dynamic effects of inertial force field and gravitational field are locally indistinguishable. Strong equivalence principle holds that the "dynamic effect" "Upgrade to "any physical effect". It should be emphasized that the equivalence principle only holds for local inertial frames, and the equivalence principle does not necessarily hold for non-local inertial frames."

With some broken English, he continued to speak, and on the drawing in his hand, there was already dense text. Just looking at it made people feel the scalp tingling.

It's just that when Jiang Chen looked at the past subconsciously, his expression couldn't help but be taken aback.

Because there is a lot of content in the mental retardation that overlaps with the content of the general theory of relativity that he has obtained.

It's like being carved out of a mold.

If there is any difference, it is that the content of the manuscript in front of him is not as complete as the vast knowledge in his mind, and there are some mistakes in some places.

But there are still traces of a person.

"This is?"

With surprise in his heart, Jiang Chen suddenly looked at the person next to him.

And at this sight, his pupils shrunk again.

The tan eyes were deep into the sockets, and there was a short, hard beard, and the hair was gray and disheveled, as if it had not been taken care of in a long time.

The familiar appearance, the familiar scene, almost completely overlapped with a figure in memory.

The only difference is that the hair of the person in front of him is not completely white, and it is not as old as the photos in the memory, but it is still a bit young.

But even a little young.

The appearance of the person in front of him completely overlapped.

Jiang Chen almost jumped up at this moment.

(first update)

Chapter [-] A Conversation Across Time and Space (Second)

Einstein.

Jiang Chen never imagined that he had just signed in in the morning and obtained the theory of general relativity, and that he would be able to meet its author, a top-level Daniel, in the afternoon.

No, maybe even big bulls can't describe him.

Compared with the other person who was blown into the sky, Einstein is the real number one in the entire modern times.

Albert Einstein, born in Ulm, Baden-Württemberg, is a modern physicist.

His theories laid the theoretical foundation for the development of nuclear energy. In order to help fight against the Nazis, he had contributed to the launch of the Manhattan Project with the assistance of Leo Szilard and others. After World War II, he actively advocated peace and opposed the use of nuclear weapons. , and signed the Russell-Einstein Declaration.Einstein created a new era of modern science and technology, and is recognized as the greatest physicist after Galileo and Newton, as well as the culmination and promoter of the critical school philosophy of science.

When I came to this world, I was used to seeing Jiang Chen, a famous historical figure.

But facing this one, his mood couldn't help but have ups and downs.

"No, no!"

"It's not right here!"

"Friends here!"

"In the special theory of relativity, if we try to define an inertial system, an infinite loop will appear: generally, an object that is not subject to external forces, in its state of rest or constant linear motion, is an inertial system; but how to determine the object Without external force?"

The voices were constantly mixed, and Einstein was constantly pulling at his hair at this time, and he pulled off a lot of hair by him.

It is conceivable that this big guy will inevitably go bald next.

Of course, he was bald or not. Jiang Chen didn't have the heart to pay attention to it.

At this time, he couldn't help but speak, and the words immediately opened.

"Sir, special relativity can't explain it, why don't you try to analyze general relativity!"

Speak with fluent English.

Jiang Chen's words suddenly made Einstein's body tremble.

"General Relativity?"

The figure suddenly looked up, and Einstein's eyes instantly turned to Jiang Chen.

It's just that Einstein couldn't help but be taken aback when he saw Jiang Chen's Asian face.

Although Einstein is not a racialist, it is undeniable that Asians are really backward representatives in this era. He did not expect that the person who opened his mouth was actually a depression.

But the surprise soon disappeared.

His expression quickly settled on the content of Jiang Chen's words.

And Jiang Chen did not disappoint him.

"My surname is Jiang, sir, just call me Jiang, special relativity and general relativity: the space-time background of special relativity is a flat four-dimensional space-time, while general relativity is applicable to any pseudo-Riemann space, and its space-time background is curved Riemann time."

"Sir should have experienced several failures, and should also understand that the special theory of relativity cannot accommodate the law of universal gravitation. Why not extend the principle of special relativity to general relativity, and use the principle of equivalence between universal gravitation and inertial force in the local inertial system, and establish a curved space-time The Riemannian geometry describes the general relativity theory of gravity."

Jiang Chen's words slowly opened, and what he said made Einstein's eyes brighter.

"Sir, go ahead!"

The voices almost couldn't wait to speak.

"Sir should know that in the precession of Mercury at perihelion, the remaining precession of 43 seconds per hundred years is long unexplained."

"In addition, for general relativity, can we make basic assumptions first?"

"Basic assumptions?"

"Simply put, the two basic principles of general relativity are: first, the principle of equivalence: the dynamic effects of inertial force fields and gravitational fields are locally indistinguishable; second, the general principle of relativity: all physical laws are The same form is used in all systems.”

"Equivalent principle: divided into weak equivalence principle and strong equivalence principle. Weak equivalence principle holds that the dynamic effects of inertial force field and gravitational field are locally indistinguishable. Strong equivalence principle holds that the "dynamic effect" "Upgrade to "any physical effect". It should be emphasized that the equivalence principle only holds for local inertial frames, and the equivalence principle does not necessarily hold for non-local inertial frames."

In the lobby, one person was talking, the other was listening, Einstein kept taking out the paper, the injured pen never stopped, and his eyes were getting brighter and brighter.

On the original trajectory, even if Einstein did not have Jiang Chen, he would have perfected the entire theory of general relativity in 1915.

This means that he already has a sufficient foundation at this time.

After Jiang Chen described the complete theory of general relativity, Einstein's eyes became brighter and brighter, and the window that was still a little foggy in his heart was opened at this moment.

At this time, even if Jiang Chen's words stopped, the movements in his hands did not stop at all.

Even some formulas, Jiang Chen felt embarrassed that he didn't seem to understand.

The corners of the mouth twitched.
