1900: A physics genius wandering around Europe

Chapter 77 Li Qiwei's transformation amazes everyone!

Under the expectant gaze of the crowd, Li Qiwei slowly stood up and said loudly: "I don't want to talk about quantum theory and photoelectric effect here today."

"Because I think it's too simple. With everyone's intelligence, I'm sure they can easily understand it."

After he finished speaking, everyone started laughing. Many people felt that Li Qiwei was very humorous and not at all like the arrogant person they had imagined.

“So I decided to talk about something very new, a frontier problem in physics that I myself am not sure about: the constancy of the speed of light.”

hiss!
Everyone was shocked.

The constancy of the speed of light involves Lord Kelvin's prediction.

Those present were all scholars in the field of physics and naturally knew the essence of the problem of the first dark cloud.

But Li Qiwei just solved the second dark cloud problem last year. Does he have to solve the first dark cloud again this year?
Even if he is a genius, he can't be this talented.

too exaggerated!

Li Qiwei took in everyone's expressions and smiled, "Of course I don't have the ability to directly solve the first dark cloud, but I want to talk about my opinion from the perspective of the constant speed of light."

"Maxwell's equations show that the speed of light in a vacuum is constant, independent of the reference frame."

"This clearly violates Newtonian mechanics."

"Physics masters have proposed that there is an absolutely stationary reference frame: the ether, which is the reference frame of the speed of light, in an attempt to resolve this contradiction."

"But we know that the Michelson-Morley experiment shows that the ether does not exist!"

"I pondered over this problem and finally got some inspiration."

"It just so happened that after the London Quantum Conference, Professor Lorentz, a Dutch physicist, came to talk to me privately."

"We discussed the issue of the constancy of the speed of light."

"Professor Lorentz suddenly had an idea. He believed that the ether still existed and that the speed of light propagating in the ether was a special case."

"Just make one assumption: the ether contracts in the direction of motion, which results in the speed of light being constant."

"In this case, the speed of light is not really constant, but a manifestation of the contraction of the ether."

"This can perfectly explain the invariance of the speed of light, and the Newtonian system will not conflict with the Maxwell electromagnetic system."

"Later, based on what he said, I gave the mathematical form of the transformation as follows."

As he spoke, Li Qiwei began to write out the derivation process on a piece of white paper. The dazzling formulas made the people present feel numb.

Only Einstein's eyes shone with a divine light, as if he wanted to melt Li Qiwei and stuff him into his brain.

Ridgeway had entered a state of ecstasy at this moment, and began to tear apart the Lorentz transformation with his bare hands. Oh no, it should be called Ridgeway transformation now.

"Please look, this is the Galilean transformation under the absolute view of space and time, which is used to transform the reference frame."

"Now, I just need to add the fact that the speed of light is constant, and a new transformation will be formed."

"I'm temporarily naming it [LQW Transformation], and its mathematical form is as follows."

When Li Qiwei wrote down the mathematical formula of LQW transformation on the blackboard after countless complicated calculations, everyone present was stunned.

Because they are physicists, and most of them are experimental physicists, many of them have poor mathematical skills.

Those who are good at mathematics, such as Born, are too young and know too little about the dark cloud problem. Without a deep foundation in physics, they can only understand a little bit of it.

"Bruce, when did you start studying mathematics behind my back?" Wilson looked bitter. Li Qiwei always came up with new things that he had never seen before.

"What a brilliant idea, Bruce! Just with this formula, you can publish a paper that will shock the physics world." Rutherford couldn't help but admire.

"Bruce, it turns out that your mathematical skills are so strong. I thought you just had an incredible imagination." Millikan said enviously. People who work in theory always look cool.

As for the other juniors, they were all whispering at the moment. The LQW transformation was equivalent to explaining the first dark cloud from a certain perspective.

The shock that Li Qiwei brought to them can be imagined. Li Qiwei enjoyed watching everyone's astonishment.

He thought to himself: I'm sorry, Brother Lorentz, I have stolen your 1904 results. I will go to Holland in a few days and treat you to a good meal.

In real history, Lorentz is known as the person who came closest to the special theory of relativity.

Because Einstein directly denied the ether, based on the absolute constancy of the speed of light, the results he derived were the same as the Lorentz transformation.

In fact, it is easy to understand. The basis of their derivation is actually the constancy of the speed of light.

It’s just that Lorentz was too deeply influenced by traditional concepts, and under the constraints of Newton’s mechanics system, he could only add ether.

However, Einstein directly believed that space-time itself is relative and will shrink, and there is no need for the existence of ether.

So the two people's formulas are exactly the same, but their physical meanings are completely different.

At this moment, when Li Qiwei's eyes met Einstein's, he saw the latter's eyes that seemed to be spewing flames.

Li Qiwei smiled slightly, he had done the right thing in feeding the child.

Among those present, only Einstein knew how earth-shaking the meaning behind this change was.

He didn't even care about everyone's reactions. He just stood up, ran to the white paper, picked up a pen and started calculating.

His tone was even a little trembling. "Bruce, do you really think this is caused by ether contraction?"

Li Qiwei matched his expression with surprise, "Are you talking about the change of time and space?"

"Oh my god, if that's the case, it's incredible. Wait, let me think about it."

"Einstein, why don't you work with me to complete this paper? The letters you wrote to me earlier have given me a lot of inspiration."

"I think you should have a place in this achievement."

"I will write to you with all the details when I return to England."

When Einstein heard this, his breathing quickened and his mouth became dry.

He couldn't believe that Li Qiwei was going to take him with him to learn such an important theory in front of so many people.

His heart was filled with emotion, but he did not feel unworthy.

Because the most important physical meaning of the formula is given by him, which is even more important than the formula itself.

So Einstein nodded heavily, suppressed his excitement, and returned to his seat.

A pair of wise eyes always stayed on Li Qiwei, with a beautiful smile on the corner of his mouth.

Li Qiwei was shocked and imagined Wang Luyao's cute appearance in his mind, which helped him avoid being turned gay by the god of love.

At this time, Wilson came out to smooth things over. He knew that this formula involved confidential information.

Although physicists like to share, they also pay attention to a certain degree of privacy, and Wilson always considers Ridgway.

"Bruce, your theory is good in every way, but I just don't understand it."

"I think you need to go back and perfect it. Once I can understand it, it will prove to be correct, just like quantum theory."

Everyone present burst into laughter.

Li Qiwei gave him a knowing smile, and then said to everyone: "If you are interested in the constancy of the speed of light, you can talk to me alone."

“Next, everyone is free to speak, or come forward and share your current research results.”
