"Quantum mechanics is a theory of physics that describes the atomic and subatomic scales. This theory was formed in the early 20th century and revolutionized people's understanding of the composition of matter. In the microcosm, particles are not billiard balls, but buzzing probabilistic clouds that do not exist in more than one location and do not travel from point A to point B through a single path. According to quantum theory, particles often behave like waves, and the "wave function" used to describe particle behavior predicts the possible properties of a particle, such as its position and velocity, with very certain properties. Some of the weird concepts in physics, such as the principle of entanglement and uncertainty, have their roots in quantum mechanics ......"

Professor Wu in the class is telling us these basic theories. I put my textbook in front of me, and I fell asleep on my desk.

"Cheng Yin, have you listened carefully?" Professor Wu stood on the podium and said sternly. All the students in the class looked at me together.

"Also, what about Cui Li? Why didn't he come to class today? ”

I watched sleepily as the seats around me were indeed empty. No, I did say hello to Cui Li this morning, how could he not have come to class?

I rubbed my eyes and looked carefully, Cui Li's textbook was still on the table, but the person was nowhere to be found. Just when I was wondering, my feet suddenly seemed to step on something. I looked down and looked, damn, Cui Li was actually lying on the ground and fell asleep. I guess I just fell off the table and fell to the ground.

I looked at him, kicked him twice, and shouted softly, "Wake up, Cui Li wake up, I'm in class." However, Cui Li did not react at all.

I had an idea and continued to shout, "Cui Li, Mo Weiwei is here." ”

Cui Li suddenly jumped up from the ground, looked around, and said, "Where is it, where is it?" ”

He searched around, but instead of seeing Mo Weiwei, he saw Professor Wu's almost mad face. Professor Wu shouted loudly, "Cui Li, what are you doing? You copied what I said in class today ten times, no, fifty times! Let's see if you dare to sleep in class in the future! The whole class looked at Cui Li with a blank face and burst into laughter.

April 17, 2022 at 12:02 p.m

Cui Li sat down beside me with a depressed face, and said angrily: "Cheng Yin, you are too uninteresting, you don't wake me up." Now it's okay, copy it fifty times, fifty times. Cui Li gestured in front of me.

"Can I be blamed for this? I've already called you, but you can't wake up no matter how you scream, you sleep like a pig, if I hadn't come up with this trick, I guess Professor Wu would have to wake you up in person. ”

"Forget it, forget it, I bought this virtual TV yesterday, and it turned out that it was more than eleven o'clock when I got home. But when I saw this virtual TV, I didn't feel sleepy at all, and I fiddled until two or three o'clock in the morning, and now I can't open my eyes. Cui Li said to me with his eyes half-closed.

"Who's to say it isn't? I didn't sleep until 1 a.m., and I was as sleepy as you were. "I ate the food on my plate.

"By the way, Cheng Yin, I didn't have time to ask you when I went back too late yesterday, how did you buy those two virtual TVs? Isn't it out of stock anymore? Did you rely on your eloquence to convince them to give you two? Cui Li said jokingly.

"Can you be eloquent? I don't have the skills. Besides, the salesman there won't sell me just because I said a word or two, right? "I continued to eat my meal.

"Then tell me what you are doing? You must know that this virtual TV is hot now,I can't buy it if I want to,And you didn't even have to line up and easily bought these two virtual TVs,If I hadn't seen it with my own eyes,I'll definitely think you're fooling me。 ”

"Well, I'm not as good as you say, it's just a clever use of the rules they've made." I said with a smile.

"Rules? What rules? Why do you talk about me getting more confused? Cui Li looked at me with a puzzled expression.

"Quite simply, when I was in the mall, I noticed that the inventory changes on the electronic screen were not after the order was printed, nor after the item was picked up, but according to the payment. Once you get the order and go to the payment counter to pay, the inventory of the order will be confirmed by the system and the numbers on the screen will change. ”

"But that's not right, Cheng Yin, we didn't place an order at the counter of the virtual TV, so the system can also confirm the inventory?" Cui Li interrupted my explanation.

"You forgot? The order system of the entire mall has not changed, which means that we can still place orders for virtual TV anywhere. Naturally, once the payment is successful, the inventory on the order will be confirmed by the system. The only thing that is different about the mall is that a temporary plan has been formulated, and this temporary plan should not have been formulated for a long time, so the idea is not perfect. I explained slowly.

"Not perfect? What does this mean? Could it be that there is something missing in this plan? Cui Li seemed to have found some sense.

"That's right, first of all, the so-called temporary system is nothing more than recording the issued order number on the computer, and it has no connection with the shopping mall's order system. Therefore, the inventory of orders we open anywhere will be confirmed by the system after payment. ”

Speaking of this, I paused and ate a few bites of the food on the plate, and Cui Li, who was sitting next to me, suddenly realized: "I probably understand what you mean, that is to say, the two virtual TVs we bought at the beginning, although we didn't get the goods, but the inventory has been confirmed and retained by the system, but when we returned to the payment office after dinner, the two stocks retained by the system were also released." So the saleable inventory of the day will become two units, that is, at that time, you deliberately pretend to be a late customer, come to the side of the counter and theorize with the salesperson at the same time as the number on the electronic screen changes - from zero to two, and you naturally buy those two TVs, is that what I said? ”

I nodded, "It seems that your comprehension ability is still good." ”

"That's ~ who am I? The smartest person in the Department of Physics! No, the second smartest! Cui Li began to brag next to me.

I hurriedly got up and picked up the plate, "Okay, okay, then you, the second smartest person in the physics department, hurry up and eat, don't be late for the afternoon class." With that, I turned around and left the school cafeteria.

As I lay on the couch drinking juice, I suddenly remembered yesterday's virtual TV, which took me two hours to master yesterday, and now I can finally show the true charm of this virtual TV.

I got up and took out the remote control of the virtual TV from the table and pressed it lightly, and suddenly a virtual screen appeared in front of me, the screen was very high-resolution, according to my estimation it could be four to five times that of a regular TV.

I pressed the button lightly again, and in an instant a huge rabbit appeared in front of me.

"I'm Rabbit Beibei, for the glory of Bunny Village, I will never let your giant evil dragon destroy Bunny Village!"

"Rabbit Beibei, I'm still a dinosaur Jiajia. My flames can burn everything, and you, hairy bunny, want to stop me? What a joke! ”

"Monster! I advise you not to underestimate me, for my strength can cut through all thorns, and my shield can block all attacks. Babe the Rabbit shouted loudly, waving her shield and sword.

"A rabbit, a rabbit with a shield, a rabbit with a sword, after all, is still a rabbit, and will never be able to soar in the sky like me. You can only run around the grassland, dig turnips, and eat grass. ”

I looked at everything in front of me speechlessly, I have to say that the resolution of this screen is really high, and this rabbit fur can be seen clearly and fluttering in the wind. But I don't have the heart to look at Bunny Bebe right now.

I changed the channel.

"Good evening everyone, our latest virtual TV developed by the company uses the latest retinal resolution technology, and the picture displayed can be said to make you immersive, and it is now selling hot in major shopping malls, almost completely sold out."

"Sold out? So where else can we buy this TV? ”

"Don't worry, this customer, our company has stepped up production, I believe it will ...... soon"

I couldn't stand this kind of boring TV announcement, so I quickly switched channels.

"Good evening, friends in front of the TV, this station will broadcast a piece of the latest news, because the virtual TV produced by the company reflects the conscience in the market, the sales are hot, and many consumers love it, but according to the latest information we have got, the largest competitor of the company Ilfa has recently had a new initiative, and its research and development of space TV is believed to be facing the market soon, when the two multinational companies will inevitably have a fierce competition. As for which company will dominate the market, we will have to wait and see. ”

Ilfa Company ......

It seems that this commercial war is about to start, and the space TV developed by Ilfa is obviously aimed at suppressing the market for virtual TV developed by Alpha Company. However, the market of the company in China has a small scaleU8Department store itself is one of the industries invested by the company,In contrast, Ilfa company has just entered the Chinese market,They are not familiar with this market,Even if the so-called space TV is developed,It may not be possible to find the corresponding channel for sales,So it is not so easy to defeat the company by virtue of this。

I stood on the shopping street and watched the crowd of people, and I couldn't help but become irritable. It's all because Yan Xiaoxue didn't come to buy pineapple noodles herself, so she would have to ask me to buy them for her, otherwise I'd be lying comfortably on the sofa watching TV now.

When I passed by the U8 department store, there were still so many people nearby, and it seemed that the virtual TV of Aerfu had occupied a large market.

But suddenly I didn't feel right, the direction of the crowd was obviously not towards the U8 department store, but in the opposite direction. I looked in the direction of the crowd and saw a brand new mall appear in front of me--- D1 department store.

I suddenly remembered, it seems that Yan Xiaoxue told me before that this commercial building was originally for selling clothing, but I don't know what reason it was closed like this, and it was renovated on a large scale. At that time, I had already found out that it was the Ilfa company that renovated this building, but I didn't expect it to be renovated so quickly, and it was also named D1 department store, which obviously pointed the finger at the U8 department store.

"Have you heard? This D1 department store has just been established and is engaged in promotional activities, and all the products are on sale. ”

"Is there a virtual TV for sale over there?"

"They don't say it on the poster, but many other items are much cheaper than those in the U8 department store opposite, and there are discount coupons now."

I watched the dense crowd and was rushing to the door of the D1 department.

Really? Can this price be much cheaper than that of U8?

I couldn't help but walk up and look at their sales posters. I was shocked when I didn't know if I didn't know it, and the price on it simply shocked me. Not only is it cheaper than U8, but it is even lower than the lowest price in the market.

The business war between the two seems to have shown its edge.

Just then my phone rang suddenly:

"Thousands of years have passed, and I have never forgotten each other's vows..."

"The years have passed in a hurry, but you are still looking at me, and you have not forgotten our tomorrow..."

"When I remember, when you forget. The memory of this fate. ”

"I still remember our vows, memories that will never be forgotten."

"Standing quietly where you have forgotten, watching the seasons change, I am thinking about you again.

I hurriedly picked up the phone, and an extremely familiar voice came from the other end of the phone: "Cheng Yin, did you help me buy my pineapple bread?" Yan Xiaoxue asked loudly.

"How can I forget your commands? Am I not on the high street? You'll be at the bakery soon, so I'll be sure to bring you a big basket of pineapple bread for you a little longer. I said flatteringly.

"Hurry up, I'm hungry. Our rabbit is hungry too, so it's just waiting for your pineapple bread. ”

"What? Your rabbits also eat pineapple bread? "I was blown away by the news.

"Of course, otherwise do you think I can eat so much so quickly?" Yan Xiaoxue said it as a matter of course.

"Okay, you tell your rabbits to rest easy, the 'rabbit food' will be here soon." I put down the phone and ran quickly in the direction of the bakery.
