I Build an Aircraft Carrier in the Ming Dynasty

In the debate, the most interesting thing was the debate about light.

Thanks to the textbook written by Wu Changqing, the Chinese people's understanding of light has been at the forefront of the world.

What kind of prism experiment has been done countless times.

The great Chinese at this time not only knew that light was composed of many colors, but also roughly knew that the speed of light was 300,000 kilometers per second.

This is what Wu Changqing told them. As for why there are so many, no one knows.

On the contrary, some people have carried out measurements, but the measured results are quite different from what Wu Changqing said.

Measuring the speed of light, with the current technical conditions, can actually be done, but it requires a very sophisticated experimental device, which no one has thought of yet.

Wu Changqing knew it, but he didn't have that much time to measure the speed of light.

Even if the speed of light is measured, the impact on real life is not particularly large.

Everything else he did was no less meaningful than measuring beams.

Although no one has accurately measured the results, not many people will question it, and more will think that their measurement level is not enough.

Going ahead of the measurement is the theoretical research, and now the research on the nature of light has been divided into two factions, they are arguing whether light is a particle or a wave.

"If light is a wave, what is its medium?"

Yin Jialin of the light particle theory asked.

The propagation of waves requires a medium, but in this empty sky, there is no obvious medium.

"There must be a colorless, odorless, invisible, extremely small primordial aura in the world, filling every corner of the world. And light is spread by this primordial aura."

Zhou Yanxue of the wave theory put forward a guess, Wu Changqing heard it, this is not the Western theory of ether.

However, the name proposed by Zhou Yanxue should be more domineering. What is the name of Hongmeng Qi?

"If there is Hongmeng Qi in the world, please confirm it with Mr. Zhou."

Yin Jiali is also a pragmatist who believes in methodology and pays attention to evidence. There is no evidence to convince him.

"It can't be confirmed for the time being, it doesn't mean that it doesn't exist, just like all kinds of rare gases are constantly being confirmed. Before it is found and confirmed, no one can say that it doesn't exist.

From the current observable light phenomena, we can know that light is definitely a wave, otherwise it cannot explain its reflection and refraction phenomenon. "

Zhou Yanxue's theory is not just guessing out of thin air, but the result of theoretical deduction based on actual observation.

There is an essential difference between this and pure speculation.

Moreover, he also said that the wave nature of light is a hypothesis, and he did not say that this theory must be correct, but it is the best way to justify it under the current circumstances.

This is the attitude of engaging in science. People who engage in science will never say that their theories are the truth, and they all welcome others to question and refute.

Idealism, on the other hand, emphasizes that a belief is correct and does not allow others to question it.

"Since you say that light is a kind of wave, how can you explain its diffraction phenomenon?"

Yin Zhili said with a smile, the diffraction phenomenon is a phenomenon that Zhou Yanxue can't justify at present, and was caught by Yin Zhili all of a sudden.

However, there is no way to beat Zhou Yanxue.

Because the light particle theory of Yin Jiali can only explain the linear propagation and reflection of light, but also cannot explain the more complex diffraction phenomenon.

This diffraction phenomenon has also tormented countless scientists in the original time and space, making particle theory and wave theory repeatedly prevail, and no one can deny the other.

Neither side could convince the other. At this time, Wu Changqing spoke again.

"Why do you have to argue about who is right and who is wrong? Haven't you thought that light may be both a particle and a wave. We can call it the wave-particle duality of light."

Wu Changqing was not a scientist in his previous life, but a technology enthusiast.

He knew that light has wave-particle duality, and he also knew the famous double slit experiment.

However, he only knew one concept, but he didn't know the specific details, so he couldn't replicate the double-slit experiment.

However, it doesn't matter, just the phrase "light may be both a particle and a wave" can bring great inspiration to Zhou Yanxue and Yin Jiali.

Before, they didn't think about it at all, because the wave-particle duality of light is very difficult to understand.

If someone else said this, Zhou Yanxue and Yin Jiali would definitely just smile and not speak.

However, Wu Changqing was both an emperor and an enlightener in the field of science, so no one would think that Wu Changqing was just talking casually.

Many people take Wu Changqing's words as the truth.

Whenever Wu Changqing opened his mouth, what he said was very meaningful.

Zhou Yanxue and Yin Jiali were still contemplating, Wu Changqing continued: "We may be able to design an experiment using..."

Wu Changqing briefly talked about the double-slit experiment that he remembered, mainly to give Zhou Yanxue and Yin Zhi an idea.

As for whether they can comprehend and get this experiment out, it depends on their own ability, he doesn't have time to give pointers.

Moreover, his ability has stopped here, and if he really wants to point him, he can't point it out.

Just like he knew the conclusion of the theory of relativity, but asking him to explain the theory of relativity would greatly embarrass him.

Zhou Yanxue finished listening

This experimental concept immediately shouted "My Emperor Shengming".

He understood, he thoroughly understood the subtlety of the experiment Wu Changqing said. And he is very sure that the experiment Wu Changqing said can confirm the properties of light.

This made him very excited, and it was a problem that had plagued him for a long time.

At the same time, it also made him admire Wu Changqing's knowledge even more.

Sometimes, he will also occasionally become narcissistic, because his research is ahead of most people, which makes him feel like an ignorant person.

But now, he found out that Jiang was still old and hot, and his knowledge was still as deep as His Majesty.

Although other people didn't understand it well, but seeing Zhou Yanxue's reaction, they also knew that Wu Changqing must be very correct, otherwise Zhou Yanxue would not have such a big reaction.

After all, Zhou Yanxue has always been known for being arrogant.

To convince him, his identity is not enough, he has to be truly knowledgeable.

Similar to Zhou Yanxue's impression, other people are also full of admiration for Wu Changqing's knowledge.

Most of the time, they believe in science.

But when looking at Wu Changqing, they couldn't help but feel a kind of superstition in their hearts.

Among them, some people actually believed that Wu Changqing was the reincarnation of an immortal.

If it weren't for the reincarnation of the gods, there would be no way to explain why Wu Changqing could understand so much at such a young age. This is not scientific.
