1900: A physics genius wandering around Europe

Chapter 124 Explanation : Creating a new definition of momentum!
Under the gazes of countless people with different meanings, Li Qiwei sat upright in the front row with his back to the world.

At this moment, his figure appeared extremely tall and majestic, giving people a strong sense of security.

It seemed like there was nothing in the world that he couldn't solve.

Previously on the stage, the high-spirited Einstein spoke so eloquently that people even forgot about Li Qiwei's existence.

It seems that Einstein could figure out the theory of relativity by himself, and he could debate with many scholars effortlessly.

Ridgwell was just a spectator, and all the glory of the theory of relativity went to Einstein.

However, everything has changed.

Planck's question is like a nail that firmly nails the theory of relativity, making it unable to move.

Einstein looked at Li Qiwei expectantly, waiting for a miracle to happen.

Suddenly, Li Qiwei moved.

He stood up slowly, attracting the attention of everyone in the venue, and then slowly walked to the podium.

At this moment, countless people's hearts are beating wildly.

what's the situation?
Bruce Lee actually went on stage. Isn't that a direct admission of the contradiction in the theory of relativity?

Could it be?

"Hiss!" Countless shocked inhalations were heard in the conference hall.

Planck looked at his most proud disciple in front of him and felt conflicted.

Through absolutely correct mathematical logic, he proved the loopholes in the theory of relativity regarding the conservation of momentum and energy.

But he also hopes that Li Qiwei can break the limits, surpass everything, and prove that the loophole itself is not a loophole.

He was probably the only person present who had such complex emotions of both opposing and supporting the theory of relativity.

At this time, Li Qiwei had already walked onto the stage. He looked at Einstein and chuckled, "What's wrong? Can't you solve it?"

Einstein shook his head, a little frustrated. It turned out that authority was not so easy to challenge. He sighed and said, "Ah, it seems that I am still not prepared enough."

Li Qiwei looked at him and suddenly felt very emotional.

In real history, the momentum-energy non-conservation loophole proposed by Planck was actually discovered by Einstein himself.

So after he published the paper "On the Electrodynamics of Moving Bodies", he immediately published another paper in which he added a conclusion.

The title of the paper was "Does the inertia of an object depend on the energy it contains?"

The final conclusion of the paper is the famous mass-energy equation: [E=mc].

There have been countless misunderstandings about this equation in later generations. It can be said that 99% of people do not really understand this equation.

The contents of these two papers combined constitute the complete theory of special relativity.

This cannot be blamed on Einstein. Anyone who is under such high stress will have their brain function slowed down.

If he were given some time to think about it, he should be able to explain this problem.

However, time waits for no one. Faced with Planck's aggressive and powerful offensive, Einstein's faith collapsed.

Li Qiwei walked up to him, patted him on the shoulder gently, and whispered in his ear: "Don't be afraid, I'm here!"

This simple sentence almost brought tears to the eyes of the God of Love, and Li Qiwei's determined eyes rekindled his hope.

Einstein simply walked off the stage and prepared to listen carefully.

The previous high-intensity response had consumed all his energy.

Now, let's leave the stage to Bruce, he thought.

So, under the watchful eyes of the crowd, Li Qiwei stood alone on the podium to fight against the big guys!
"Just now, my teacher, Professor Planck, asked a very good question."

"But what's the good thing about it?"

"The good thing is that, as a top physicist, he proved one thing to us."

"That is, if we do not regard the thinking of relativity as our inherent thinking, but always use the thinking of Newtonian mechanics."

“Even the greats in the field of physics make mistakes.”

"Yes, Professor Planck's loophole is wrong."

"The law of conservation of momentum still holds true in the theory of relativity!"

boom!
The atmosphere in the conference hall was completely ignited.

Everyone was stunned and stunned.

Some people even cursed in their hearts, Bruce, is there something wrong with your eyes? Planck has already made it very clear with mathematical derivation.

Momentum is not conserved in relativity!
You actually said it is conserved. Are you bullying us because we don't understand physics?
Even Planck was confused, wondering if his student was stupid.

It's obviously not conserved.

Facing the misunderstanding and doubts of the crowd, Li Qiwei smiled gently, "I know that many people have doubts. The formula has already shown that it is not conserved."

"But we must always remember that when discussing relativity, we must use relativistic thinking." Then, Li Qiwei began to draw diagrams and calculate. "Momentum, energy, mass, these concepts are all concepts under the Newtonian mechanics system."

"But in relativity, these physical quantities need to be redefined."

"The purpose of redefinition is to ensure that the law of conservation of momentum still holds true after the LQW transformation."

"So we need to define momentum as this, see the big screen."

"When the speed v approaches the speed of light, the relativistic effects cannot be ignored, and this is what it looks like."

"Then plug it into the LQW transformation, and lo and behold, the math remains the same, momentum is conserved!"

"And we can see that when the speed v is much smaller than the speed of light c, the denominator becomes 1."

"At this point, momentum returns to the definition of Newtonian mechanics [mv]."

"Relativity is perfectly compatible with Newtonian mechanics."

"Is it powerful?" Li Qiwei added jokingly at the end.

Wow!
Li Qiwei's sudden move made countless people's eyes pop out.

Wow, the definitions of momentum in Newtonian mechanics and relativity are actually different.

The key is that under low-speed conditions, relativity perfectly covers Newtonian mechanics, and the momentum returns to its original state.

Anyone with normal logic can understand that Li Qiwei's idea is correct.

Originally, the theory of relativity is a system in itself, and time and space only change under the system of relativity.

Then the momentum must naturally change as well. Only after the change will it remain conserved.

In this way, the law of conservation of momentum is correct, and the theory of relativity is also correct.

Li Qiwei solved this contradiction perfectly.

"Oh my God, what's wrong with Bruce's brain? This genius idea must have been told to him by God himself."

"Genius, genius, genius. There is really no other word to describe Bruce. I feel like he is the embodiment of physics."

"Bruce is going to be invincible. With such an extremely sharp physical mind, who among all the physicists in the world can compete with him?"

Everyone was completely impressed by Li Qiwei's wild imagination.

Planck stared blankly at the newly defined momentum with his mouth wide open.

I didn't expect Bruce to resolve the conflict in this way.

Nothing is wrong. The only thing that is wrong is using the thinking of Newtonian mechanics to substitute the theory of relativity.

He found that Bruce had been thinking in the theory of relativity from the beginning to the end, so everything seemed reasonable.

Planck had no doubt that his student's contribution to this theory was definitely not low, at least not less than that of Einstein.

Bigwigs like Roentgen, Thomson, and Rutherford were all dumbfounded.

I didn't expect the truth to be so simple.

"Hahaha, this Bruce has never disappointed anyone."

"His thinking is different from ours. I guess he has turned himself into a beam of light, always thinking about physics problems from a high-speed perspective."

Einstein's eyes sparkled, "Yes, I didn't think of this angle."

"Any physical law must undergo LQW transformation to be consistent with the theory of relativity."

"Oh, Bruce, I am really inferior to you. Hehe, I give in."

"You only need to make a slight move to make me admit defeat."

Facing the wonderful expressions of the crowd, Li Qiwei remained very calm.

This is actually a matter of a thin layer of window paper, but few people can always turn their thinking around.

After all, no one can keep telling themselves subconsciously: You have to eat with your feet.

Planck looked at Li Qiwei with relief, his eyes full of kindness. He had perfectly overcome his mental tribulation.

So he said, "Bruce, the same is true for energy, the definition needs to be revised."

Li Qiwei smiled and nodded, "Yes, Professor Planck."

The people in the audience nodded silently, thinking that it was very common, and they just had to modify the definition to conform to the LQW transformation.

There is nothing special about the energy estimate.

Bruce won this round, and it was an effortless and easy win.

His every gesture and movement reveals the demeanor of a top physicist, which makes people worship him.

Li Qiwei took in everyone's expressions and laughed softly in a voice that only he could hear:
"Haha, the following deduction of energy will give you a little shock."
