Since going to school for a physics class that day, Lu Zhou hasn't been out much in the past week.

In the past, when he was in Princeton, he would drive to a nearby Walmart to buy groceries, but now it's better that he even leaves the groceries to others to do the grocery shopping for him.

Although he always bothered Wang Peng to help him deal with things outside of work, which made Lu Zhouwei embarrassed, he was embarrassed many times, and he became accustomed to it.

On the other hand, during the week of his retreat, a lot of things happened outside.

The most important of these is probably the East Asia Electric Power Company.

Around the second day of his retreat, East Asia Power, which had completed the reorganization, reached an agreement with the State Grid Suzhou Provincial Electric Power Company. At the same time, the 12 ferrofluid generating units at the Tianwan Nuclear Power Plant have finally completed their final commissioning and are officially connected to the grid for power generation, delivering clean and cheap electricity to the entire province of Jiangsu Province at a fairly cheap and still profitable price.

In the entire Jiangsu Province, the changes brought about by the Pangu fusion reactor grid connection can be most intuitively felt, except for Haizhou, which is close to the water, and it is probably Gusu in Suzhou Province.

This important industrial town located in the middle of the Yangtze River Delta can be said to support half of China's high-tech industries. With a population of just over 10 million, the annual electricity consumption is almost equal to that of Shanghai, which is next door, breaking through the order of 150 billion kilowatt hours a few years ago, and now it is running for 200 billion kilowatt hours.

With the official integration of the Pangu fusion reactor to the grid, under the coordination of policies, the industrial electricity price in Suzhou Province has been cut in half directly.

This can be said to be a blessing from heaven for those manufacturing owners in Suzhou Province.

Especially for a large power-consumer such as the semiconductor industry, the production cost is simply falling by a visible margin.

At the moment of the global economic downturn, the grid connection of the fusion reactor is like a manna for the manufacturing industry in the entire Soviet province.

On the surface, the decline in energy costs only makes electricity cheaper for factory owners and entrepreneurs, but in fact it changes the future of the entire city and even the owners of this urban agglomeration.

When production costs have fallen, enterprises have money, they have the confidence to update production technology, and they have the capital to develop automation and electrification. When the cost of electricity is cheaper, the industrial structure of the entire city and even the province will shift in the direction of being more biased towards the core area of the industrial chain.

This is a subversive revolution by the energy structure. The economic effect brought by life is much more effective than directly subsidizing a bunch of fraudulent moths.

At the same time, in addition to industrial electricity prices, residential electricity prices in Haizhou, Gusu, Jinling and other cities have also seen a stepwise reduction of 10%~20%.

However, it is spring, and it is not yet the peak of summer electricity consumption, and most people do not obviously feel the impact of the reduction of electricity prices on their lives, at most they are surprised when they see the electricity bill, or even have a surprised expression.

After all, the process of a society moving from the past to the future is often not achieved overnight, but subtly.

However, judging from the macro data, with the reduction of electricity prices, the demand for the entire electrical appliances and new energy vehicle market has increased significantly.

Maybe after a while, there will be two or three more electrically driven buses in front of the Gusu Garden.

Maybe in another year or two, smart devices such as sweeping robots have unconsciously spread to every household, and wired or wireless charging piles have also unconsciously spread from gas stations to the parking lots of every shopping mall.

And in three or five years, perhaps even small parcels of express delivery and takeaway will begin to be handled by drones shuttling between high-rise buildings.

Humanity's quest for efficiency is eternal.

It's 2020, and it's only the first year that Pangea has been connected to the grid for power generation.

As for what the more distant future looks like, I'm afraid only the future will know.

……

For the first time since his mathematics grade was promoted to LV8, Lu Zhou calmed down and focused on thinking about a pure mathematical proposition, and this was the first time he experienced the gap between LV8 and LV7.

This difference is not reflected in calculations.

Rather, it is embodied in a transcendence of thinking.

It's hard to describe this feeling in detail, but if he had to talk about his feelings, it would be that when he threw himself into thinking about mathematical propositions, everything in the outside world seemed to slow down.

When the speed of thinking is fast enough, time can't keep up with the pace of thinking?

This statement may be a bit idealistic, but this is indeed the most intuitive feeling of Lu Zhou.

Of course, even though the speed of his thinking has become faster, when he is immersed in research, his sense of time is even thinner. Often unconsciously, a whole day has passed, so much so that in the end he has to rely on his stomach to remind himself.

Stopping the pen in his hand, Lu Zhou pinched his eyebrows and looked at the time in the lower right corner of the computer screen.

"Is it already ten o'clock?"

It was dark outside the window just now, but it was so bright in the blink of an eye.

Of course, what surprised him more than the time was the date.

From the last physics class to now, he didn't expect that a week had passed, and he didn't even feel it at all.

Reaching out and opening the curtains, looking at the paper basket stuffed next to the corner of the table, and the handwriting on the stack of scratch paper on the table, Lu Zhou sighed, pushed away the chair and stood up.

"It's really not that easy to solve......"

However, he has not been without success in the past few days.

At least the existence proof of the solution, he is only one point away from completion.

Objectively speaking, the mathematical difficulty of the Young Mills equation is not as maddening as the NS equation.

In particular, after solving the problem of the existence of the solution of the NS equation, the L manifold and the "differential topology method of differential equations" obtained in his research were also very effective in solving the existence problem of the solution of the Jan Mills equation, saving him at least more than a month of work.

If it weren't for today's events, he would probably have been in retreat forever.

However, it is the tenth week from today.

He also has a computational materials science class to take in a moment.

If his PhD students are good enough, he can give him this task.

But unfortunately, Wu Shuimu's current level in computational materials science is far from being able to take charge of himself, at least compared to the two apprentices he brought in Princeton, one master and one doctorate, so he still has to do it himself.

Standing at the door of the study, Lu Zhou thought for a while, cleared his throat and said.

"Xiao Ai, clean the room for me...... Except for what's on the table. ”

A string of clean bubbles pops up in the bottom right corner of the computer screen.

【Okay, master!】 (๑•̀ㅂ•́)و✧】

After a while, a drone flew in through the open window and flew out of the window hanging a paper basket. Immediately afterwards, the sweeping robot wiped Lu Zhou's trouser leg and rushed into the study and began to clean up the garbage on the floor.

The corners of his mouth curled, Lu Zhou glanced at the busy little ones in the study with satisfaction, and after handing over the place to Xiao Ai, he turned around and walked downstairs.

I haven't been out for a week, and it's not just the room that needs to be cleaned up.

After taking a hot shower, Lu Zhou, who came out of the bathroom after drying his hair, changed into clean clothes, stood in front of the mirror for a while, and then walked to the entrance.

However, just as he was about to put on his shoes, the doorbell rang outside.

Through the camera at the gate of the courtyard, seeing the person standing at the door, Lu Zhou was slightly stunned.

Yan Yan?

What did she come for.

Although he had some doubts in his heart, Lu Zhou still pressed the button to open the door and opened the security door with his hand.

After a while, after crossing the path on the lawn in the front yard, Yan Yan, who was dressed in casual clothes, walked into the house.

After meeting, she didn't say hello, just glanced at him.

"You missed yesterday's physical examination."

“…… Uh, is there such a thing? I don't think I remember exactly. ”

Lu Zhou vaguely remembered that Wang Peng had told him about this the day before yesterday, but when he answered the phone at that time, he was thinking about the problem, and he really couldn't remember what he said.

Looking at Lu Zhou's bewildered expression, Yan Yan sighed: "I know you're busy, and everything has been sent to you...... By the way, you haven't had breakfast yet, have you? ”

"I was about to eat ......" Looking at the plastic cup and cotton swab she handed to herself, Lu Zhou was slightly stunned: "...... This is? ”

Yan Yan's eyebrows raised: "One is for collecting manure, and the other is for urine, don't you need me to help you?" ”

Lu Zhou: "...... No, thanks. ”

Originally, he was planning to have a meal and then go to class.

It's okay now, he doesn't have much appetite to be by her like this.
