Liu Yun'er was not just angry, she even wanted to take a fruit knife and stab Lin Fan directly in the back, so that he could feel the power of anger, he really regarded himself as a god, and it would be solved in minutes...

Boom!

I slammed the door so hard that it almost didn't collapse.

Lin Fan looked at the direction of the door with a frightened face, and didn't know what to say for a while, although he didn't see what the problem was, but the calculation process of deriving Hardy's theorem, such a simple problem, would not be stumped by himself.

unless

The conditions given are not sufficient, otherwise you can know the general steps with a glance, and you don't even need to type a draft.

"This woman..."

"It's always so frizzy. Lin Fan sighed, and then devoted himself to the game.

meanwhile

Room 304 opposite 305.

Liu Yun'er was sitting in front of her notebook, still thinking about what happened just now, although the plan had been successful, but she didn't have any joy after success, but she had no place to vent her anger, and that guy was still as angry as ever.

Hum!

Then we'll wait and see!

See if you can fix it... But don't brag about it!

Time flies,

In an instant, it was midnight,

Lin Fan ended the day's happy hour and stretched out... Then he collapsed in the chair, and then his stomach was hungry, and he used to encounter this situation, take a shower and sleep, and carry the hunger pangs, but I don't know why... This time it's a bit overwhelming.

Rummaging through the cabinet, he found a bag and hurriedly glanced at the production date... There was still one day before it expired, and then I poured myself a cup of coffee, and while drinking coffee and eating bread, I watched the sand sculpture video on the Internet.

In fact

Men's happiness is very simple, games make them eliminate negative energy, exercise to extend their lives, scare people to reduce work pressure, watch sand sculpture videos to relieve social anxiety, so... To sum it up briefly, life without a girlfriend is so happy and free.

suddenly

A WeChat prompt came from the mobile phone, and when I glanced at the screen, it turned out to be from the refrigerator at the door.

Yun: Did you sleep?

Wardday Nivisenmo Ramoshuai: Sleep.

Put down your phone,

Xu Mang ate bread, looked at the computer screen, and smiled stupidly.

Thirty seconds later,

WeChat is here again.

Cloud: Is it difficult?

Wardday Nivisenmo Ramoshuai: I don't know, just finished the game, wait a minute.

Yun: Can you go faster?

“...”

"She seems to be in a hurry, what is there to rush about. Lin Fan put down his phone and continued to watch the sand sculpture video, but in less than ten minutes, Liu Yuner sent WeChat again, this time the content on it was very simple, just two words.

Yun: Sleep.

Lin Fan didn't bother to go back, just sleep... I also let me know that it seems that after you fall asleep, you will have a chance.

In less than five minutes,

Lin Fan solved the bread, and drank half of the coffee, silently pressed the pause button, got up and walked to the table, picked up the copy paper left by Liu Yun'er, returned to the computer, glanced at the content on it, and in an instant... He was confused.

"Huh?"

"It's... This does not seem to be sufficient. Lin Fan found that this seemingly extremely short formula, if it is taken apart, W1 = W2 = 0, from W2 = 0 and the second property can not be deduced from the measurement data of U1 at all, similar U2 can not get the result.

According to local realism, if U1=1 and U2=1 are determined by local hidden variables, W1 and W2 are not measured.

Odd...

Is there a little bit less ahead?

But what's missing?

Lin Fan looked at the above formula, and entered his brainstorming time, he was looking for a sufficient condition that could satisfy all doubts.

Put the blue axis mechanical keyboard on the side of the Internet café, and then find a pen, and start to reverse deduce on the white paper, Lin Fan's original intention is to find the last sufficient condition according to the existing formula, and then go back and continue to solve.

Half an hour later,

Lin Fan got the conclusion he wanted, in a kinai... There are cases that are neither orthogonal nor parallel, so far... In the short formula, with respect to not equal to zero and equal to zero, you can choose another suitable basis and then extend it.

in a word

Lin Fan felt that the refrigerator was not lying, and this problem was particularly difficult... It took me more than half an hour just to find a suitable condition, and I had to calculate... However, the calculation should not be a problem, and it will take up to ten minutes at most.

Another ten minutes passed,

Lin Fan had deduced almost all the calculation processes, and it took a total of about fifty minutes, including brainstorming time.

"Oops..."

"What a special spirit!" Lin Fan stretched his waist, found that he was completely sleepy, looked at the cup that had bottomed out, and couldn't help but start thinking about a question... This year's Nescafe has reached such a powerful point that you can't fall asleep after a cup?

"Forget it..."

"Let's keep playing. ”

This play,

It's just an all-nighter.

...

early morning

Six.

Liu Yun'er woke up on time, her day began at this moment, different from Lin Fan... In addition to dressing and washing, she also has to put on makeup simply, but Liu Yuner has always put on light makeup.

At half-past six,

Send a voice call request to the scum across from you.

"Get up!"

"Oh..."

After hanging up,

Liu Yun'er left the room with her satchel on her back.

After waiting in his car for about fifteen minutes, in the process, Liu Yun'er had already thought of all the words to mock Lin Fan, to be angry with him, and at this time... She saw Lin Fan walking over slowly, then opened the car door and sat in directly.

"You..."

When the words came to her lips, Liu Yun'er suddenly found that this guy's mental outlook today was very poor, and the whole person exuded a decadent temperament.

"You didn't sleep?!" Liu Yun'er asked curiously.

"Huh?"

"Hmm..."Lin Fan nodded, and said helplessly: "Yesterday I poured myself a cup of coffee, and..."

"And then toss until now?" Liu Yun'er said angrily: "Didn't I let you go to bed early!

Looking at his tired face, Liu Yun'er silently suffocated the sarcastic words back into his stomach, he was for that question... Tossing until morning, what right do you have to mock him? To mock a person who is serious about solving problems.

"That question..."Lin Fan had just spoken, when he was suddenly interrupted by Liu Yun'er.

"You don't have to say it. ”

"I know that the problem can't be solved, because of the lack of sufficient conditions, the reason why I let you solve it is just..." Liu Yun'er paused, silently turned her head aside, and said softly: "I just want to see how powerless you look, I'm sorry... Keep you without a night's sleep. ”

Lin Fan was a little confused, and even a little caught off guard.
