I really don't want to lie down and win

"Ugh..."

"It's so annoying!" Xu Mang sighed. If it wasn't for his wife, he would have torn up these contents a long time ago. It's not easy being a man, and it's even more difficult being Xiaoman's man.

How to do?

What else can I do, who let me marry such a woman.

Putting aside the conversion rate of perovskite batteries, its lifespan is also a big problem. The current silicon plate in service has 25 years, and can perovskite reach this time?According to the data, there are some difficulties.

also,

Perovskite is also very sensitive to air and moisture, but this can be protected with transparent materials, the most serious thing is the crystal structure of the perovskite itself, damn it... in some cases, when the perovskite heats up, it will happen Structural changes, although reversible, still affect power generation efficiency.

Xu Mang was very desperate,

This question is a bit difficult, in short... let's talk about it when we return to our country.

The next time, Xu Mang had a very tormented life. Who knows how, when everyone in the classroom was gone, Xu Mang was woken up by Yang Xiaoman's pat, raised his head and looked around, and asked in confusion: " What about people? Why are there no more people?"

"It's over!" Yang Xiaoman said angrily: "I am in class, did you not listen to a word? Do you know how long I prepared last night? You big pig's hooves... have no respect at all. Me, I'm so mad!"

"Cough cough..."

"I can't help it either." Xu Mang said awkwardly, "What if I don't understand? I'm so honest, I automatically fall asleep if I don't understand. By the way...you didn't get paid for the speech?"

"No."

"But give me the position of honorary professor." Yang Xiaoman said seriously: "Tomorrow I have an open class. By the way...you accompany me, otherwise I will be nervous. You don't want to see your wife because Are you nervous and suffering from depression?"

Xu Mang:

I...

Oh my God!

Two days wasted in vain, but the vacation can be extended.

leave the classroom,

Xu Mang and Yang Xiaoman planned to go to the scenic spots in the afternoon, but when they passed by the Mathematical Physics and Life Science Building, Xu Mang was suddenly stunned. There was a blackboard next to the gate, with nothing written on it, and it was empty.

"What's wrong?" Yang Xiaoman asked, "Is there a problem?"

"It's written on this blackboard, the smartest question maker and the best solver." Xu Mang frowned, and said seriously, "Is there no genius in this university?"

"What do you want to do?"

"Don't make trouble... You are in a foreign land, you have to do as the Romans do, in case someone else takes a machine gun and beats you to death the next day." Yang Xiaoman stood on tiptoe, gently pinched Xu Mang's ear, She said softly: "Be good...or I will beat you up, old lady."

Ugh...

Speak the most vicious words in the most gentle tone.

hateful!

But Xu Mang has always been rebellious, otherwise he would not have married Yang Xiaoman. He silently picked up the chalk and wrote down a calculation. This process only took half a minute. He turned around and said with a smile, "Let's go... .”

"This..."

"What's all this?" Yang Xiaoman asked with a confused face: "What kind of monster have you started to be again?"

"A mathematical formula."

"Chen Hardy Littlewood's theorem needs to be used." Xu Mang said indifferently: "Although it has not yet reached the world-level difficulty, it is enough to make science students, professors, scholars and experts at Pacific University confused for half a year. "

"cut!"

"My mother, I don't believe it." Yang Xiaoman said disapprovingly: "You are not the smartest in the whole world, I believe there are people who are smarter than you."

finished,

Suddenly sprinkled dog food, held Xu Mang's prosperous beauty, and said seriously, "But you are the only genius in my heart!"

"Let's go!"

"My knight, this princess wants rainbow ice and ginger ale!"

...

in the afternoon,

A professor Dwyake, who is engaged in mathematics research, went to the Mathematical Physics and Life Sciences Building with his own materials. As soon as he entered the building, he saw that the blackboard next to him was full of content. The professor stopped.

almost a year,

There was another content on this blackboard. Although he came up with this idea two years ago, it only lasted for less than a year, and then everyone's enthusiasm dropped. The lack of reward mechanism made many people lose power.

Unexpected,

It appeared again.

The professor took a few steps towards the blackboard, and saw a not-so-complicated formula. He didn't pay attention to it at first, but when he was about to solve it, he suddenly realized that the formula was not as simple as it seemed.

"what..."

"Who wrote this?" Professor Dhuaike's scalp was tingling at this time. The deeper he went, the more he felt that this calculation formula was not simple, and it had completely exceeded the scope of his own comprehension. Logically speaking, it didn't look like a student wrote it. Yes, but there are not many professors engaged in professional mathematics. After all, Pacific University is weak in academics and natural sciences.

Damn it,

Who the hell wrote down this bastard's calculation?

Professor Dwyake picked up the phone, took a picture of the content on it, and then emailed it directly to a friend of his. He is a professor of mathematics at Princeton University, and he can gather and dance with madmen. As a professor in the Princeton Department of Mathematics, his strength is extraordinary.

for a long time,

When Professor Dwight returned to his office from the professor, suddenly his cell phone rang, and it was his friend.

"Dwyke!"

"This...is this what you came up with?" The professor of the Department of Mathematics of Princeton University asked hurriedly with a hint of surprise in his words: "This...this is very difficult. Just now I and other students from the Department of Mathematics The professor researched it together and found that...a variety of proofs are needed."

"None of you can do it?" Dwyake asked in surprise, "I know it's difficult, but I'm a little surprised that it's difficult for you."

"Say..."

"Did you come up with this?" asked the professor.

"No!"
