In addition to the universe, Chen Xu also told Shen Yiqiu about some unsolved mysteries on the earth, such as the Pyramid of Khufu, which is considered to be a product of an alien civilization or the earth's heritage of the previous generation!

The Pyramid of Khufu is not only the largest of all the pyramids, but also because it contains a wealth of astronomical and mathematical knowledge.

For example, dividing the circumference of the Pyramid of Khufu by twice its height gives a quotient of 3.14159, which is the π of pi.

This accuracy exceeds the 3.1428 pi calculated by the Greeks.

And it wasn't until 3,000 years later that Zu Chongzhi calculated pi to such an accurate degree.

The right-angled triangle chamber inside the tower, with a ratio of 3:4:5, reflects the value of the Pythagorean theorem.

In addition, the pyramid is also a 52-degree "angle", the "shape" of a square cone, and the "bit" that moves synchronously with the magnetic field lines, which is the mystery of the stability of the pyramid.

But how did the ancients 4,500 years ago know that a 52-degree angle is a stable angle?

How do you know how to defuse a desert storm with a square cone?

And how do you know to lay the foundation of the huge tower in the center of the magnetic field lines?

It's all an unsolved mystery.

Chen Xu told Shen Yiqiu about the mysterious earth and the vast starry sky of the universe, didn't he remind himself?

Remind yourself not to dwell on your current achievements and all kinds of temptations, the world, the universe and endless secrets are waiting for him to discover!

Of course, the meal still has to be eaten one bite at a time, and the road has to be walked step by step.

When the sea level was white, Chen Xu and Shen Yiqiu ended the call.

……

From the first day of the new year to the fifth day of the new year, all kinds of complicated things squeezed out all of Chen Xu's free time.

At one o'clock in the afternoon on the sixth day of the Lunar New Year, Sun Liqun, chairman of the microelectronics company, called Chen Xu and invited him to have afternoon tea, and Chen Xu happily agreed.

After arriving at the locality, the two sides had a preliminary exchange on the issue of cooperation.

On the morning of the first day of work, experts from microelectronics companies came to the Sioux City Science and Technology Park to visit the light source and lens laboratory.

Chen Xu personally accompanied.

Through reverse reasoning engineering, Xiaobai has completely mastered the preparation process of light sources and lenses, and now what is lacking is experience.

Sun Liqun and a group of experts came to the No. 1 laboratory of Xingsi Semiconductor that had just been put into operation, and their eyes almost didn't fall off.

Looking down from the glass-covered viewing platform above, in the dust-free laboratory of nearly 10,000 square meters, countless humanoid robots have replaced the experimenters who should be humans.

These robots run according to a certain trajectory route, skillfully operating all kinds of machinery and equipment, and there will be absolutely no delay in the middle, just like machinery, very shocking!

No, they're inherently mechanical.

Nor is it ......

What Sun wants to convey is that these robots behave more like humans than like robots, while these robots retain the high efficiency of machinery.

It's incredible!

"Mr. Chen, these robots ......"

Chen Xu didn't return, but led a group of people down the stairs with a smile, and after changing into dust-free clothes at the entrance, he brought everyone into the laboratory.

Chen Xu beckoned a robot to come over and show everyone around.

Sun Liqun, Lu Jiarong and more than a dozen lithography machine experts immediately surrounded them.

"This is our latest scientific research robot invented by Xinghai, and their control system is ......," Tang Li, the head of the laboratory, introduced to the experts of the microelectronics company.

Soon, the scene suddenly resounded with bursts of exclamation.

Chen Xu laughed secretly as he listened to it.

The control system of these robots is indeed very intelligent, but it has not yet reached the point where it can do experiments independently, all thanks to Xiaobai, who can already control 500 robots at the same time to run independently!

However, Sun Liqun and his entourage don't know much about artificial intelligence, and after a series of professional terms such as deep learning and convolutional neural networks popped up in Tang Li's mouth, only amazement and admiration were left in his mouth.

After visiting the robot, Sun Li came to the light source laboratory.

This is the main purpose of this trip.

The preparation process of 10nm makes the whole person tremble just thinking about it.

At present, China's entire semiconductor industry is almost completely backward, and SMIC, the only one that can get its hands on it, is still competing in the 28nm process technology, while Samsung, TSMC and Intel have been mass-produced on 10nm, and the gap in the middle is very huge!

If Xinghai Technology can really solve the preparation process of 10nm, it will enable China to catch up in the semiconductor industry chain, and it is not without opportunities to achieve corner overtaking on the ultimate track of 7nm in the future!

Soon came to the light source equipment laboratory.

Chen Xu was just about to explain to everyone, but at this moment, Su Yiren walked over quickly and whispered: "Mr. He of Hai Strontium is here." ”

"Where?"

"It's right over there in the science park. ”

"Oh?" Chen Xu asked, thought about it, said hello to Sun Liqun and them, and then led people away.

The interior of the headquarters building has already begun to be renovated, and trucks loaded with materials can be seen whizzing past the heading of the headquarters building.

There are also a lot of trucks with huge solar panels on them.

Along the way, there are countless green workers at work, and the crane truck transplants the metasequoia trees with a diameter of 20 cm into the holes that have been dug long ago.

In February, the metasequoia trees have all lost their leaves, and this is also a good time for transplanting.

Chen Xu looked all the way and quickly shouted, "Stop!"

Jiang Chaohai immediately stepped on the brakes, and Chen Xu pulled the car door and walked towards the greenery on the side of the road.

Just after the New Year, the weather was still very cold, and the wind hurt on the face like a knife.

When he arrived next to Metasequoia, he stretched out his hand to Xu Zedao, the secretary who followed behind him, and said, "Give me the ruler." ”

Xu Zeren immediately took out a laser ruler from his handbag and handed it to him.

After Chen Xu took it, he opened the laser ruler and measured it, 2.36 meters.

Changed one, 2.25 meters.

Another one, 2.31 meters.

"What is the metasequoia spacing?"

Xu Zeren immediately replied: "The metasequoia branch is very small, the main trunk is straight, so the crown width is also small, and the planting is relatively dense, and the diameter like this should be 2 meters ~ 2.2 meters / plant spacing." ”

"Yes, 2.2 meters! I remember that the construction requirements were also written like this, so why is there a maximum error of 16 centimeters?"

Chen Xu asked Xu Zeren to give the laser ruler, turned around and walked towards the car, and said as he walked: "With this work attitude, what is the use of asking them?"

Tell Wang Yadong to let the relevant person in charge roll up and get out!"

"Got the boss. ”

When he came to the Science and Technology Park, He Tingbo was visiting along the main road outside the headquarters building!

After some greetings, everyone came to the engineering headquarters facing the lake in the east.

He Tingbo couldn't wait for the tea to come and couldn't wait to ask: "I heard that Xinghai is cooperating with a microelectronics company to develop a 10nm lithography machine, is it really fake?"

"Hehe, Mr. He is quite well-informed. Chen Xu said with a smile.

Although he has explained to the microelectronics company that this matter must be kept strictly confidential, he also knows that industry insiders like He Tingbo will definitely know about it in a short time.

"Yes, yes. ”

He Tingbo's pupils dilated a little, his face showed an excited look, and his breathing began to become rapid, "That... How sure is that?"

"One hundred percent!"

He Tingbo stared at Chen Xu for three seconds, and finally gave a thumbs up and said, "Cow!"
