The staff member looked confused. He saw several math seniors quarreling over eight blackboards like shrews, which completely subverted his three views.

Zhou Jimin had no way of knowing how the eight blackboards were distributed.

After returning to the farm, Zhou Jimin locked himself in the room again and told the clerks not to disturb him unless there was something urgent.

"Director Zhou, what about your three meals a day?"

"No, I have prepared bread in the room. You can do what you want. I will take care of myself."

When Xiao Lin and other clerks heard this, they looked at their leader with embarrassment.

Looking at the closed door, the leader was also speechless.

When Hua Lao and the others came back, they just smiled bitterly when they heard Zhou Jimin was so active and did not stop him.

Because I can't stop him, I just let him go.

In the space, Zhou Jimin turned on the violent mode, determined to write the paper as quickly as possible.

Although he has not exposed his number seventeen these days, everyone is not a fool.

Every time I see Zhou Jimin asking questions, I naturally understand that he has in-depth research in many fields.

Previously, Zhou Jimin published papers through the square root number seventeen and so on, which involved many fields in mathematics.

In the eyes of the outside world, these vests should belong to several people, but unexpectedly they are the same person.

Although Zhou Jimin did not admit it, everyone acquiesced.

However, mathematics is pure, and no one has exposed this matter.

At the same time, because the exchange meeting is still going on, everyone is busy researching their own topics. How can anyone be free to gossip about trivial matters?

It didn’t take much time, and several papers were published.

After rechecking it several times, he put the paper aside.

After writing the thesis, he turned around and devoted himself to the research of sound insulation materials.

For the time being, the aviation engine materials have been completed, and engine materials with stronger thrust are the next step in the plan.

At this stage, sound insulation is the most important issue.

Who doesn’t want to have the same quiet experience on an airplane as when flying in a Rolls-Royce?

He was not talking about the Rolls-Royce of the 1960s, but the Rolls-Royce of later generations.

In his previous life, he was lucky enough to ride in a Rolls Royce, which was his boss's car.

At that time, he was sitting in the passenger seat, and his boss and his Xiaomi were in the back seat.

After arriving at his destination, he was about to get off the car, but the driver unexpectedly asked him to wait.

Sure enough, after almost five minutes, the boss opened the door and got out of the car.

The moment he opened the door, Zhou Jimin heard clearly that there was music playing in the back seat.

Nest grass!

At that time, the back seat was separated from the driver's seat in front, but he didn't hear any sound at all.

The driver was quiet and didn't speak himself.

After Xiaomi got out of the car, Zhou Jimin noticed that the other party's black stockings had turned into jeans.

So, it was music plus car vibration, but he, sitting in the passenger seat, didn’t hear any movement at all.

He didn't know if all Rolls-Royces had such excellent sound insulation, but the Rolls-Royce he rode in at that time was definitely the best.

But Zhou Jimin checked the silent design of Rolls-Royce and found that this thing actually added 130 kilograms of sound insulation material, which made him speechless.

The weight of a Rolls-Royce is about 2.5 tons, and the sound insulation alone takes up 130 kilograms of material.

Putting it on an airplane is naturally not allowed.

Therefore, Zhou Jimin began to conduct research on many materials such as thermal and sound insulation ultra-fine glass fiber cotton, ultra-light environmentally friendly flame-retardant and sound-insulating composite aviation materials, low-density graphene airgel sound insulation materials, melamine resin foam sound-absorbing sponges, etc.

There is only one goal, and that is to perfect the sound insulation system.

The noise reduction effect of the Mercedes-Benz car did not quite meet his requirements, or in other words, this was his helpless choice.

But after today's relevant papers on topological space theory came out, he felt that as a mathematician, he should not stagnate, but should bravely challenge difficulties.

After he completed two sets of experiments, the alarm clock on his cell phone suddenly rang at this time.

He had no choice but to stop what he was doing and go to the wind tunnel laboratory on the other side to check the condition of the engine.

These two engines have initially completed indoor testing. Judging from the test results, all materials fully comply with laboratory requirements.

What needs to be done now is to take it outdoors for final testing.

In order to maximize the safety and power testing of aerospace engines, he built two wind tunnel laboratories directly in space.

It completely simulates the weather conditions for aircraft flying in the sky, such as heavy storms, snowstorms, and rain.

This is not a simple test, but a certain value of flight simulation data must be reached before the next step of assembly can be entered.

In Zhou Jimin's experimental plan, he planned to let the engine undergo at least 500 hours of rigorous aircraft testing before letting it leave the test bench.

As we all know, the thrust of commercial engines is generally stronger than that of fighter jets.

However, the latter's engine size and weight are much smaller than the former.

The middle involves factors such as the engine's bypass ratio, boost ratio, combustion efficiency, etc.

Wanting more thrust and getting a smaller and lighter engine is indeed what fighter jets and commercial aircraft are pursuing.

But the two are not the same.

The engine designed and built by Zhou Jimin is naturally stronger than another aircraft engine in the space, but it is much smaller in size and weight, and its combustion efficiency will be higher.

However, the combustion efficiency only increased by 3%.

Next, he needs to go through a thousand hours of continuous testing, so he will need more aviation fuel.

The aircraft equipped with this engine is not a commercial passenger aircraft, nor a fighter jet, or a transport aircraft, but a small aircraft similar to a private jet.

According to the drawing design, this will be a luxury private jet that can carry eight people, and will be equipped with a bedroom for rest.

But other than that, there is not much difference from the private luxury jets of later generations.

After all, he doesn't need much indoor space. He even said that he only needs a fighter jet.

Because most of the time he just needs its flying ability, rather than enjoying its luxury.

But fighter jets are still too tricky, and once discovered, they can easily be targeted.

Therefore, in fact, in the next stage, invisibility, noise reduction, etc. are the directions he should consider more.

After turning on various instruments in the wind tunnel laboratory, adjusting the settings for simulating ice and snow conditions, and adjusting the alarm clock, he left the space.

Sound insulation materials, let’s continue the experiment after he comes back.

An oil processing plant located outside the suburbs of Wudu receives hundreds of tons of crude oil from different places every day.

However, today, they received a notice that crude oil supply will be stopped in the short term.

"Fake, how can you stop the supply? If you do this, you will go to hell, do you know?"

Factory manager John received a report from the employee below, and he quickly called his partner for consultation.

However, the latter informed him with regret, and also informed him that he had mentioned this matter yesterday, but you just didn't listen.

Bitch, when did you notify labor and management?

John was so angry that he cursed as harshly as he wanted.

Unexpectedly, the other party suddenly hung up on him, and John became even more angry.

At this time, Douglas, the crude oil supplier on the other side, a shipping company, hung up helplessly and shrugged at Zhou Jimin opposite:

"John's temper is so bad."

"Let's not talk about these unhappy things. Peter, the cargo of crude oil you want will arrive at the port the day after tomorrow..."

"Should I pay the deposit?"

The deposit Douglas mentioned is not the first deposit, but the second deposit after the crude oil arrives at the port. The final payment must be received after the crude oil is delivered.

This order was an order that Zhou Jimin had discussed with John the day before yesterday and confirmed yesterday.

The reason why he came to see the other party again today was naturally because he hoped that the other party would deliver two thousand tons of crude oil today.

After all, experiments have already begun in space, and he does not want to stop the test midway because there is no aviation crude oil.

Just now, Douglas called John to inform him that the crude oil supply would be stopped for the next half month.

After all, Zhou Jimin was a big customer. He ate a cargo of crude oil in one bite and bought it at a high price.

The current international crude oil price is two dollars a barrel, but Zhou Jimin paid two dollars and three dollars to buy all the crude oil in that shipment.

A cargo of crude oil costs a total of two million tons, totaling 300,000 tons. With a price increase of only 0.3 US dollars, Douglas can make a huge profit of 600,000 US dollars.

With such crazy profits, let alone just asking Douglas to inform John that these old friends would stop supplying for half a month, he would have no objection at all even if they no longer cooperate.
