A nation's industrial development begins with junior engineers.

What's the strangest thing?

Hmm, cough cough.

That's the double-slit interference experiment. Although both this experiment and the Sagnac effect involve the interference of light, their experimental principles, purposes, and applications are significantly different.

The Sagnac effect describes the phase difference that occurs when two beams of light propagate in opposite directions within the same loop in a rotating reference frame. This phase difference is caused by the optical path difference due to the rotation. This phase difference can be measured by the shift of interference fringes.

The double-slit interference experiment of light is mainly used to verify the wave nature of light and study the interference phenomenon of light, involving constructive interference and destructive interference of light.

Well, now that I've said this, you readers will probably accuse me of padding the word count, but that's really not the case.

The Sagnac effect is a proven and well-established theory that can be directly applied to laser gyroscopes. However, the double-slit interference experiment with light is a bit...unconventional.

In layman's terms, the results you observe are completely different from the results recorded by the experimental equipment.

In philosophical terms: Is it possible that the result comes first, and then the cause?

To paraphrase Schrödinger: Is a cat still a cat when I'm not looking at it?

Okay, if you've ever thought about these kinds of questions, my friend, you've grasped the essence of quantum mechanics!

What's that saying again: When in doubt, turn to quantum mechanics?

Hahaha……

I've digressed, let's not get confused. The essence of this book is still about industrial development and national rejuvenation. I don't want to get involved in the century-old feud between the man who was hit by the apple and Huygens for now.

However, during his conversation with several bigwigs, Jiang Xia suddenly realized that the famous double-slit experiment with electrons had not yet been figured out by outside scientists.

Wouldn't it be perfect to use the double-slit interference experiment, a topic that has been debated for generations, to publish more papers and improve China's current academic standing, which is not even ranked highly?

Look at it this way. In terms of industrial machinery, Jiangxia has been flapping its butterfly wings as hard as it can, but it still hasn't dared to say that it has reached an advanced level. The transistor computer that they managed to develop by exploiting a bug is at best at the world average level (not counting the subsequent research on architecture and operating system, since there are no results yet). The only thing that can be considered a dimensionality reduction attack is the "C language and TCP/IP protocol family". But these two strategically important things cannot be publicized in a big way.

But the double-slit experiment is different. Although Thomas Young had already put together the famous "Young's double-slit experiment" in the early 19th century and used it to prove that light is a vibrational wave.

But who would have thought that Einstein, this top genius, would prove the particle nature of light in the early 20th century through the photoelectric effect theory?

Wow, this is going to make things interesting in academia.

In 1924, a guy named de Broglie proposed a makeshift theory: wave-particle duality.

This theory is like a pushover: "Yes, yes, you're all experts, you're all right!" Light possesses both particle and wave properties, which temporarily reconciles the two theories.

However, with the development of technology, Thomas Young's simple experiment has been modified in various ways by his peers, and each iteration of the modification has brought unexpected experimental results.

Jiang Xia was once very fascinated by these experiments.

He remembers all sorts of imaginative experiments, like being able to be in two places at once, the instant his mother comes home, or deciding later.

What's interesting is that some of these experiments are actually just brainstorming ideas, but as soon as you bring them up, they will amaze people who are deeply immersed in Bohr's theory, state functions, and Pauli's principle.

As for the difficulties in carrying out such an experiment, they can be summarized as "a few dark clouds in a clear sky."

Just like the blackbody radiation problem and the photoelectric effect experiment, there are many things that cannot be explained.

Using this to refresh the outside world's perception of our academic work is perfect.

To communicate and exchange ideas, you need to have something that others don't have, right?

Otherwise, nobody will play with you, and you'll end up with nothing...

Alright, that's enough. I reckon your brains are almost cooked by now, and the author is almost cooked too.

Just between you and me, the person who proposed the "Yang-Mills gauge field" was truly a great scientist, even when it came to patriotism...

Starting in 1971, he returned to China for one or two months almost every year, unwavering even in the face of threats and slander from the United States and Taiwan...

He is the only living physicist on the ultimate list of physicists.

The reason it's called the Investiture of the Gods might be because it lists people like Newton, Einstein, Maxwell, and Schrödinger...

……

If we're going to play, then we should play the "most beautiful physics experiments".

Yes, it's the experiment where electrons are emitted one by one and interference is clearly observed on a detection screen—Johnson's double-slit experiment.

Hehehe, this experiment is easy to observe. With the current level of technology, we can manage to get the basic equipment we need with a little effort.

Jiang Xia had prepared a thought experiment for them after this experiment, namely the famous Wheeler delayed choice experiment.

It's just a brainstorming session. Since the experimental equipment doesn't even meet the standards, why can't this experiment be called the "Berlon Delayed Choice Experiment" or the "Peishu and Xide Delayed Choice Experiment"?

Hey, right, Little Ao Mao played a big game this time.

Teacher Pei Shu, Teacher Xi De, Dr. Lan Ying, and Senior Sister Ze Hui all appeared in Xiao Dai Mao's office without missing a single one.

Zehui's husband had only agreed to be her errand driver because he couldn't refuse his wife's request, but he also became engrossed in listening to Xiaodai Mao's idea of ​​"double-slit interference experiment of electrons".

Scientists, especially top scientists, have a great interest in these cutting-edge things.

The eldest sister's husband turned around and ran back to the Academy of Sciences, bringing with him Dr. Guangzhao (guess the name!), who had just returned from abroad, and Professor Yu, who had been holed up in his office for almost half a month and was almost stinking (no need to guess this one).

Also traveling with them was Teacher Deng, who had just crawled out of his burrow and spent two months as a groundhog.

Sparkling stars!

That wasn't all. When Senior Sister Zehui saw her husband desperately pulling people over, she turned around and made another phone call to several elderly people.

"Hey, that Light Cliff, there's a particle experiment here that looks really interesting, wanna come and take a look?"

"Hey, you there, is my sister Chengshu back in Beijing yet?"

"She's back? That's great! Let her answer the phone. Sister Chengshu, that kid who does centrifuge gas fractionation and diffusion purification is right next to me. Do you want to get involved?"

"Come on! Okay, we sisters haven't seen each other in so long, come quickly, come quickly."

"Oh? Brother Jia is right here with you? Isn't he teaching in Nanjing? He's coming too? Okay, come quick, come quick..."

Jiang Xia's eyes were already darting around as he listened to the name of the person invited by Senior Sister Zehui.

Oh dear, I feel dizzy, I feel dizzy.

Can a single electron double-slit interference experiment really uncover so many big shots?

No, I can't faint! Old Wang, you son of a bitch, where did you take my camera...?

(If anyone can recognize all of these people, I'll consider you amazing!)
