Time always flies by quickly when you are studying!
Of course, for poor students, studying is always the most painful time, and it is no exaggeration to say that every day feels like a year.
Otokogawa finally came out of his high-level research state. Although the Goldbach conjecture had not been completely solved, the theoretical system of topology and the large sieve method had been constructed, and it was not difficult to prove the Goldbach conjecture.
This theory, which he named the sieving method, will soon be available to the world. And for the mathematical community, under the same conditions, the tools created when solving a problem are more important than the problem itself.
Fields Medal, if Xiao Yi can make the proof of Goldbach's conjecture and the sieve theory he founded accepted and recognized by the mathematical community before September.
Then, for the Fields Medal, which is known as the Nobel Prize in mathematics, the name "a small string" will no longer be a nomination.
Mathematics is the domain of geniuses. A Sequence 9 scholar is just a scholar, or a reader in foreign countries. He can only enhance his memory. Even a Sequence 8 scholar is not worthy of the title of genius. Only a Sequence 7 thinker can have some effect in the field of genius.
Unfortunately, it seems that few young scholars in the mathematics community have awakened to this reality.
Even if a few students in the university mathematics department woke up and developed in the direction of pure mathematics, the time was too short.
As for those people who can be called bigwigs in mathematics, they are too old.
Age is inversely proportional to the success rate of awakening, and no country will take this risk.
Therefore, Otokogawa successively broke through two major conjectures on prime numbers, one is the "Zhou conjecture" and the other is the "twin prime numbers", which can be said to be unique in the world.
But, it’s pure numbers!
After all, it is a purely theoretical subject!
I was doing some boxing and stretching as usual, and just after I finished my meal, Lao Liu called and said that the organization had distributed equipment.
Yi Xiaochuan looked around and didn't see Wang Chao. It seemed that he was still in the prehistoric world. What a poor guy. Who knows what will happen when facing lizardmen all day long...
Oh, by the way, it seems that the woman from Jinling is preparing to go to the prehistoric world!
I don’t know whether he went there or not.
Thinking about the few energy crystals left in the "imaginary space", Xiao Yi felt that the time for the next copy was not far away.
Headache!
It would be great to stay at home and watch the level of black technology improve every day.
With a faint smile on his face, Zhang Wei patted the safe in front of him, and then his jade-like green fingers tapped rhythmically on the lead safe.
"Everyone has witnessed the efforts of everyone in the past few days. Whether it is the discovery of the prehistoric world, the extermination of the Midnight People, or the battle with the head of the police, our Jiangcheng Emergency Response Team has received high praise from the higher-ups. The bonus is inevitable, 100,000 per person..."
Old Zhang with squinting eyes curled his lips and said, "Not enough." As for Yi Xiaochuan, the old Liu couple, and Ling Ran, the surgical genius of the First Hospital, they didn't care much.
Firstly, I am not short of money, and secondly, I have no place to spend money!
The organization takes care of food, accommodation and transportation.
Zhang Wei raised his eyebrows and continued, "... This is just pocket money. There are some things that money can't buy. The real treasure is the things in here, which are life-saving equipment... Lao Liu, first of all, your equipment... Tsk tsk, even I am a little envious."
As he spoke, his fingers danced on the electronic code, and then he pressed a fingerprint, and the lead safe opened.
Everyone looked over curiously, and saw Zhang Wei taking out a bronze lamp covered in verdigris. It didn't look particularly magical, and it looked like it had just been taken out of an ancient tomb.
"This is obtained from ancient relics. You can figure out its specific function yourself. I think it is much better than your pipe. Your soul fire will benefit a lot from being nurtured by this bronze lamp..."
Old Liu took it with a smile on his face, stroked it with his hands, and couldn't let it go.
“What a good thing!”
Zhang Wei took out an iron soup ladle with a long handle from the safe and said to Zhang Weihong, "This is a custom weapon for you. It's made of the same material as the chain used by the head of the police..."
Then Zhang Wei took out two scalpels and handed them to Ling Ran. The material was also the same as the captain's chain.
As for the slanted-eyed Old Zhang, it was a box of silver-white bullets engraved with mysterious patterns.
Xiao Yi also got a box of ten bullets, but Lao Zhang's were pistol bullets, while his were sniper rifle bullets.
This is the rune bullet, also called the magic-breaking bullet.
The "door god" Qin Qiong's is a small bottle. The liquid inside is like liquid and smoke. Even if the light is not very strong, it still emits a dazzling light, which looks colorful and psychedelic. At the same time, if you look closely, you can find that there seem to be countless tiny bubbles inside that are constantly being born and dying, and it even makes people feel that life is continuing in this constant birth and death. It looks amazing.
Sequence potion!
Otoshi Ogawa was shocked.
"You decide the time to take the medicine. Call me when you are ready..." Zhang Wei handed over the small bottle, but Qin Qiong did not take it. Instead, he shook his head.
"I'm not ready yet, so leave it alone for now."
"Okay..." Zhang Wei put the potion back into the safe and locked it.
Old Zhang looked at the bullet in his hand with a squinting eye and said with some disappointment: "Boss, is that all?"
"Don't worry, there are... the rest are new equipment made by the national scientific research department, the second-generation stab-proof suit. After you put it on, ordinary rifle bullets can't hurt you. This stab-proof suit cannot be mass-produced yet. We only got two. Yi Xiaochuan, you and Zhang Tao take one... There are also high-performance electric shock devices and mobile phones that can be on standby for a month, one for each person..."
Otogawa took the stab-proof suit first without hesitation. The material was as soft as ever.
Prepare for an "extraordinary appraisal", but unfortunately, this is not an extraordinary material, but a technological creation.
"Can a mobile phone last for a month on standby? Who developed this battery?" Xiao Yi looked at the stun gun and the mobile phone. If the stab-proof suit was pure black technology that he could not understand with his knowledge of materials science, then this battery could not be beyond the scope of his knowledge!
"It seems to be the result of research conducted in the United States. It's called lithium battery!"
"Has there been a breakthrough in lithium battery technology? How do you solve the problem of lithium dendrite growth? If it's not solved, be careful of fire and explosion!"
"… "
How do you want us to answer this question
Including Zhang Wei, everyone studied the equipment in their hands with a calm look on their faces.
You are so knowledgeable that you will have no friends.
Forget it. Xiao Yi just searched on Baidu and downloaded the battery of the stun gun and studied it.
After all, he has reached level 1 in materials science and energy science.
We can only get a little bit of information from the news, but it is true that the problem of lithium dendrite growth has been solved, and a breakthrough has been made in lithium batteries.
As for why lithium batteries have such fascinating magic, we have to mention the concept of energy density.
Energy density refers to the amount of energy contained in a unit volume. As the most important indicator for measuring the performance of a battery, improving energy density has always been the pursuit of the industry.
Even in China's 13th Five-Year Plan, it is clearly stated that the power battery technology level should be synchronized with the international level by 2020, and the production capacity should remain the world's leading. The most important red line is to increase the energy density of power batteries to 300-350wh/kg.
The battery in Xiao Yi's hand, which was covered with English instructions, obviously already exceeded this standard.
It’s a pity that the core technology is in the hands of Americans!
