If you want to say that girls are serious about something, it is very certain, take Gao Yaxuan as an example, she is sure that it is very hard, and even in class, she is pondering every sentence in the script.

In order not to affect the class of other students, she decided to sit in Niu Zihao's position. Zhao Liyang felt relieved to see that the student she liked at the same table was sitting next to him now, but she wanted to see what was different between the girl Niu Zihao liked and ordinary people.

The teacher is lecturing in class, and the other students do what they have to do.

What puzzled Gao Yaxuan was why the art class was put in the first period, the air was so fresh in the morning, and it was a very good idea to go to math. But the school sometimes puts math and physics in the afternoon, and it can be tolerated in winter, but if it's summer, oh my God, just kill me with a sword.

There are a lot of people who chew gum, and most of them are girls. There are also boys who find it boring, so they just take out their mobile phones and read the novel. It's a writer who hits the street and writes it in his spare time, only smoke and rain are left, and the pen name is good, and it has rich cultural significance, but the book is too slow, and it is only in chapter 73 that I don't know when I will see the next chapter.

Those who don't have mobile phones flip through books, and some even stare at their watches, and when the hands just bypass the number 12, thankfully, it's a minute closer to the end of class.

Although Yang Changwei played the role of Gao Yuanli in the drama, this shows that he attaches more importance to music. When it comes to art, it's just his hobby.

The teacher talked about it with relish, but there were very few people listening. The sound is in the ears, but it can't enter the heads of the students. Du Fu is very busy, but not all of his classmates are idlers.

Yang Changwei tore off a post-it note and began to depict the "Pounding Practice" drawn in the book, which is a famous painting of the Tang Dynasty in China, which is a painting with a fine brush and re-coloring, showing the work scene of aristocratic women pounding and sewing. To say that ancient women were industrious, they would do all kinds of work. The current 21st century is definitely very different from the Tang Dynasty. Nowadays, women are pampered and have to rely on their boyfriends for everything. You know, the pressure on boys is very great, buying a car, buying a house, and having a down payment. Don't say it, it's all tears

At the same time, it is also an important genre painting in the Tang Dynasty, which has a significant impact on the painting style of later generations, and is a relatively unique work in the Tang Dynasty ladies' paintings, which is the work of Zhang Xuan, a painter in the Tang Dynasty.

It would be great if I could also draw a masterpiece that is shocking. Yang Changwei's ballpoint pen "clicked" chaotically, and he was still in a fantasy. It's better to have a museum collection, that's even better, a painting can be bought for millions of dollars, it's simply a treasure in human history. Yang really thinks too much, his paintings are not "shocking", at most they are "shocking".

This Tang Dynasty painting was originally in the collection of the Old Summer Palace, but was looted and lost overseas after the "burning of the Old Summer Palace" in the 60s of the 19th century, and is now in the collection of the Boston Museum in the United States.

Hearing this, Yang Changwei couldn't help but take a deep breath. Why, why should our Tang Dynasty things be taken away by foreigners! However, this is a problem left over from history. If you have the chance, you can visit the Boston Museum.

At the same time, Li Min, who was in a comatose state, felt severe cranial nerve stimulation. Haven't you been solved by the Demon Star Spell, how can you be here?

Looking at the situation, he was obviously in the chaotic light wave of the seven-dimensional space, and with the passage of time, the numbers on the clock and instrument kept reversing from 2020 downward, and finally stopped at the moment in 1887.

Li Min opened his hazy eyes, and his surroundings made him feel stunned, isn't this a unique Austrian architectural style? Could it be that I not only traveled through time, but also transcended life and death, and was finally exiled in this pure land with the light of physics.

At this time, a special energy field was generated around him, which took him to Schrödinger's laboratory. A thought experiment proposed by the famous Austrian physicist Schrödinger in 1887 referred to the fact that a cat was kept in a closed container containing a small amount of radium and ***. There is a chance that radium will decay, if radium decays, it will trigger a mechanism to break the bottle containing ***, and the cat will die; If radium does not decay, the cat survives.

At this time, Schrödinger sat on the chair, looked at the kitten beside him, and thought deeply with a deep frown.

According to the theory of quantum mechanics, since radioactive radium is in the superposition of decay and non-decay, cats should be in the superposition of dead cats and live cats. Although Li Min had read some popular science books and mentioned this experiment, he didn't dare to disturb the people doing the experiment. It seems that this Brother Xue can't see himself, nonsense, how can the two of them see it after more than a hundred years, just like can you see your future, impossible things.

This cat that is both dead and alive is the so-called "Schrödinger cat", this cat is also quite pitiful, those great people like to use mice when doing certain experiments, how to change to a cat here Schrödinger. Maybe cats are bigger than mice, which is more conducive to the observation of experiments, Li Min analyzed it like this.

However, it is impossible to have a cat that is both dead and alive, and the result will not be known until the container is opened. Whether it's dead or alive, you can see it at a glance.

This experiment attempts to explain the problem of the quantum superposition principle at the microscopic scale from the macroscopic scale, and cleverly connects the existence form of the microscopic matter with the macroscopic cat whether it is a particle or a wave after observation, so as to verify the existence form of the quantum at the time of observation.

Looking at the essence through the phenomena of things, nothing can be guessed. Only the conclusions reached through experiments can finally stand firm.

Dear time-traveler, can you analyze which branch of physics is involved by watching Schrödinger's experiment just now?

A. Atomic Mechanics

B. Quantum Physics

C. Astrophysics

D. Electromagnetism

Without any doubt, Li Min chose B. Of course, the answer was correct, and the system also asked him to write the Schrödinger equation, and he also wrote it correctly, ▽2ψ(x,y,z)+(8π2m/h2)[E-U(x,y,z)]ψ(x,y,z)=0.

Things that are very complicated for ordinary people are indeed very simple in Li Min's head, he loves to learn and like to study, and sure enough, his first prize in physics is well deserved.

Li Min's notebook records such a sentence, Einstein said: God does not play dice, but quantum mechanics makes us have to believe that God seems to play dice.
