A century of family life: Eternal life since the Republic of China

Einstein.

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

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

Compared with the other person who was blown into the sky, Einstein is the real first in the entire modern era.

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

His theories laid the theoretical foundation for the development of nuclear energy, helped to fight the Nazis, helped with Leo Szilard and others in the launch of the Manhattan Project, and after World War II he actively advocated for peace, opposed the use of nuclear weapons, and signed the Russell-Einstein Declaration. Albert Einstein ushered in a new era of modern science and technology, and is widely regarded as the greatest physicist after Galileo and Newton, as well as the master and promoter of the critical school of scientific philosophy.

When I came to this world, I was used to seeing the historical celebrity Jiang Chen.

But in the face of this one, his mood couldn't help but have ups and downs and fluctuations.

"No, no!".

"Here, it's not right either!".

"Buddy here!".

"In the special theory of relativity, if we try to define an inertial frame, there will be an endless loop: in general, an object that is not subject to an external force is an inertial frame in which it remains at rest or in a uniform linear motion, but how can we determine that an object is not affected by an external force?".

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

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

Of course, he is bald or not, Jiang Chen has no heart to pay attention to it.

At this time, his heart couldn't help but move, and the words immediately spoke.

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

Speak fluent English.

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

"General Relativity?".

The figure suddenly raised its head, and Einstein's gaze instantly looked at Jiang Chen.

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

Although Einstein was not a racial element, it is undeniable that Asians are really backward representatives in this era, and he did not expect that the person who spoke up turned out to be a depressed person.

But the surprise quickly faded.

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

And Jiang Chen didn't disappoint him.

Special relativity and general relativity: the spatio-temporal background of special relativity is a straight four-dimensional space-time, while the general theory of relativity is applicable to any pseudo-Riemannian space, and its spatio-temporal background is a curved Riemannian space-time. "

"Sir should have experienced several failures, and he should also understand that special relativity cannot accommodate the law of gravitation. Why not extend the principle of special relativity to general relativity, and establish the theory of general relativity to describe gravity by Riemannian geometry of curved space-time by using the principle of the equivalence of gravitational force and inertial force in local inertial frames. "

Jiang Chen's words slowly spoke, and the content of what he said made Einstein's eyes brighten up more and more.

"Sir, go on!".

The voices almost couldn't wait to speak.

"Sir should know that in the precession of Mercury's perihelion, the remaining precession of 43 seconds per hundred years cannot be explained for a long time. "

.......

"Also, for general relativity, can we make basic assumptions first?".

"Basic assumptions?".

"To put it simply, the two basic principles of general relativity are: first, the principle of equivalence: the kinetic effects of the inertial force field and the gravitational field are locally indistinguishable, and second, the principle of general relativity: all laws of physics take the same form in any frame of reference. "

"Equivalence principle: It is divided into weak equivalence principle and strong equivalence principle, and the weak equivalence principle holds that the kinetic effects of the inertial force field and the gravitational field are locally indistinguishable. According to the strong equivalence principle, the "kinetic effect" is elevated to "any physical effect". It should be emphasized that the equivalence principle is only true for local inertial frames, and not necessarily 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 became brighter and brighter.

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

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

After Jiang Chen narrated the complete general theory of relativity, Einstein's eyes became brighter and brighter, and the window in his heart, which was still a little foggy, was instantly 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 was embarrassed to find that he seemed to be a little incomprehensible.

The corners of his mouth twitched.

I looked at Einstein, who was still stuck in his own thoughts.

Jiang Chen got up quietly.

He was ready to slip away.

Signing in, although the general theory of relativity and the corresponding application of the general theory of relativity have been obtained, but that's all.

In the face of this kind of history, the real top bull in the physics world.

Going on, he felt like he was 100 percent good at goofs.

Running away after pretending to be forced is the best choice.

But fortunately, Einstein was completely silent in it, and he didn't bother to pay attention to it at all.

He didn't notice that Jiang Chen had quietly left.

And when he left completely, Jiang Chen couldn't help but let out a long breath.

It seems that you still have to weigh it in the future, otherwise, it will be easy to pretend to be a fool.

If he hadn't slipped away quickly just now, Jiang Chen felt that something would definitely be wrong.
