The natural constant, symbolized by e, is a constant in mathematics, an infinite non-cyclic decimal, and a transcendent number, with a value of about 2.718281828459045.

It is the base of the natural logarithmic function.

In the mathematical system, the natural constant e, like the π of pi and the imaginary unit i, is one of the most important constants.

Many people know the π of pi, but they don't know much about the natural constant e, because the existence of the natural constant e is not as easy to understand as π.

Take a real-life example to understand the magic of the natural constant e.

If you have 100 yuan in your hand and deposit the money in the bank, the bank will give an annual interest rate of 100%, which means that after a year, 100 yuan will become 200 yuan.

However, a year is too long.

You want the interest to be calculated semi-annually and ask for a half-year interest rate of 50%.

The bank agreed.

Then you think about it carefully and think that you can take out the money and deposit it in half a year, so that you can realize the operation of rolling profits, and the money taken out after a year becomes 225 yuan.

Since you can get more interest, you should consider depositing and withdrawing once every three months at a fixed interest rate of 25%, so that you will withdraw more money after a year.

Then go ahead and go to the segmentation.

Take it once a month, once a week, once a day......

In this way, can't you rely on access operations and directly become a monopoly?

Of course not.

No matter how fine the division is, even if you are saving and withdrawing money every minute, the money you withdraw after a year will tend to be close to an extreme value.

e。

This is how the natural constant e is defined.

In mathematics, whenever the concept of growth is involved, the natural constant e will still appear.

In nature, whether it is the growth and reproduction of living things, or the decay of radioactive materials, there are many ways of growth such as compound interest.

e stands for some kind of "limit value of growth", which is an internal law.

If π represents a perfect circumference, then e represents a perfect growth.

When e is understood as the 'limit value of growth', and the number of 'limit value of annihilation energy' is close to e, it naturally feels like it is no coincidence.

"So, e may be closely related to the structure of energy particles and the process of annihilation?"

"If e is the limit value of annihilation energy, then if there is a limit for the atom to undergo an 'ascending change', is there also a limit, and is it related to e?"

"There doesn't seem to be a relationship between the two......"

“……”

Wang Hao thought carefully.

If e is the limit value of annihilation energy, there must be a very important principle in it, but it is very difficult or even impossible to determine the value through experiments, because there must be deviations in experimental testing.

From the theoretical analysis, e is the limit value, which is much more reliable than the experiment.

"Theory, how do you start researching?"

Wang Hao thought deeply for a long time, and didn't have any clue, and then simply decided to give up for the time being, or focus on the technical improvement of field strength.

The experimental group continued to work on the problem of material layout design improvement.

Half a month later, the research team completed a new experiment.

The results of the experiment were remarkable.

They created a strong annihilation force field of the 'Grey Space' nature and determined an intensity value of 4.23.

"Annihilation energy data is also out......"

"96 percent!"

He Yi said excitedly, "This data is no worse than the strong annihilation force field compressed inside the spiral force field!" ”

Not only He Yi was excited, but everyone was excited.

After two months of hard work, they developed a new technology to create a strong annihilation force field, and the strength of the field force was close to the strong annihilation force field compressed inside the spiral force field without the intervention of the strong magnetic field repulsion method.

It's incredible!

He Yi finished talking about the data, and sighed, "This is the best way to create a strong annihilation force field, not a complicated way to superimpose the force field......"

"yes, that's the best way to do it."

"It was too complicated before, but I didn't expect that DC strong voltage is the best way."

"The technology has been improved, and it can create a strong annihilation force field in an area instead of the original thin layer, and the most important thing is that the equipment consumption is greatly reduced!"

The latter is critical.

Originally, the method of creating a strong annihilation force field was 'anti-gravity field superposition', which used several devices to create an anti-gravity field and superimpose it, combining them to form a thin layer of a strong annihilation force field.

Now it's a device that directly creates a strong annihilation force field.

At the same time, the other gains are also significant.

At the meeting of the research group, Yan Jing held the document and said seriously, "In the past two months, we have conducted a total of eleven experiments, and the highest strength has been created with a strong annihilation force field with an intensity value of 4.23. ”

"Except for the experiment to determine the critical value of annihilation energy, the other experiments have improved the data compared with the previous time, and the numerical comparison is also very stable."

"I have discussed with Xiao Xinyu, Xiang Qiansheng and Professor Liu Yunli, and they all believe that this upward trend will continue until it creates 6 times to 8 times the field force before it declines......"

This is the conclusion of the analysis of several experiments.

They have experience in studying anti-gravity technology, when researching anti-gravity technology, when using a new material, the anti-gravity strength produced by each experiment will show a steady upward trend at the beginning, the closer to the extreme value of the strength that the material can make, and the improvement of the internal material layout of the equipment, the slower the strength will rise.

After listening to Yan Jing's report estimates, Wang Hao nodded with a smile and said, "I also did calculations, and the data is about the same." ”

Yan Jing suddenly exhaled lightly, as if she had gained a lot of confidence, and she continued, "At the same time, we will measure the corresponding ferromagnetization reaction value in each experiment. ”

She said and pointed to the projection screen.

After a simple operation of the notebook, a correspondence between the strength of the annihilation force field and the strength of the ferromagnetization reaction appeared on the screen.

She walked up to the screen and introduced, "Let's look at this connection." ”

"Comparing the two data, it is obvious that as the intensity of the annihilation force field exceeds 3, the growth of ferromagnetization reaction intensity shows a downward trend."

"But for now, the downward trend is not much."

"Based on this curve, we can roughly predict the intensity of the F-rays that were originally manufactured. Our analysis is in the range of '7 to 8'. ”

Yan Jing said and looked at Wang Hao again.

Wang Hao didn't make a judgment for the first time, looking at the numerical comparison chart on the screen, his expression was very serious, and he kept making calculations in his head.

When it comes to mathematical analysis, his thinking is much more rigorous.

Good half a day.

Wang Hao sat in his position and didn't move.

While the others waited patiently, they also discussed in a whisper, "What is Academician Wang thinking?" ”

"Is it to calculate the intensity of F-rays based on the data? Isn't this a comparative analysis of data? There's no way to do the calculations, right? ”

"He probably had something in mind?"

"I don't know, just wait."

Yan Jing, Xiao Xinyu and others are also very puzzled, their so-called 'rough prediction' is that several people get together, combine the experimental data and the experimental results related to F-rays, and make a very simple judgment.

As for whether it is correct or not, it doesn't seem to matter very much.

Mainly because they don't think that based on some experimental data, they can calculate the intensity range of F-rays.

While the others were still whispering, Wang Hao suddenly stood up, walked to the whiteboard at the side of the conference room, picked up the pen and began to write.

He started with a data comparison table.

Next, we started the analysis and calculation by substituting various data, and then continued by substituting some of the original experimental data, and the column formula became more and more complex.

One line, one line after another......

By the time I wrote a dozen lines, the people in the conference room couldn't read it.

Wang Hao continued to write with his pen, his hand movements were uninterrupted, and he didn't even think about it later, as if he was copying something against something.

Party.

Another line.

It wasn't until he had written half of the big tabula rasa that he listed a combination of algebraic sequences, and then used the previous function to do a calculation, and came up with the final result.

After Wang Hao finished writing, he looked at it from beginning to end, exhaled lightly, turned around and said, "There is a 34 percent chance, and the intensity of the F-ray is 6.8." ”

"Other intensities may be in the range of 6.6 to 7.9, and in terms of probability, they are almost evenly distributed......"

At this moment, the conference room fell silent.

Everyone was digesting what had just happened, and they didn't expect that the intensity of F-rays could be mathematically predicted accurately.

The most important thing is that it took Wang Hao less than ten minutes to do the calculation.

He added some other experimental information along the way, such as the strength of the magnetic field, the magnetization reaction of iron, etc., which made the analysis even more complicated.

In the course of subsequent calculations, he also quickly solved a complex equation.

It was really a complex equation, and when it was written, no one else knew how to solve it.

They do experimental physics, but the level of mathematics is not low.

Wang Hao easily solved it.

"That's the gap!"

"If it weren't for just now, I almost forgot that Academician Wang is a very good mathematician, and mathematical analysis is his old profession!"

"Yes, I remember when I first knew about Academician Wang, he had several research achievements related to mathematical analysis."

"Effective and irrelevant carry screening, don't you know?"

"I've heard it, it's too complicated."

Xiang Qiansheng couldn't help but sigh quietly, "I, Yan Jing and Xiao Xinyu have been studying together for a long time, and I would have known that it would be good to let Academician Wang calculate." ”

"Then why don't you count?"

"The level is not enough!"

Wang Hao ignored the surprise of others, but was thinking about the value of '6.8'.

Estimation of the intensity of F-rays is very important.

If it is possible to create a force field that catches up with the intensity of F-rays, or if a new technology can be used to create F-rays of the same intensity, the new technology can definitely catch up with the old technology.

Then they can abandon the old technology.

At present, the research group has adopted the new technology to create a strong annihilation force field with a strength of '4.23', which is close to the strong annihilation force field inside the spiral force field of the old technology.

If a strong magnetic field repulsion method is added, the strength of the force field can be continuously increased, and in the same way, F-rays can be created.

It's just intensity......

"It's uncertain."

Wang Hao said seriously, "There may be differences in the repulsion effect of F-rays made by two different methods by strong magnetic fields. ”

"In the original technology, the inside of the strong annihilation force field was an anti-gravity field, but now there is only a strong annihilation force field, and the anti-gravity field that may exist in the outer layer cannot be detected for the time being."

"So, the next step is to continue to increase the intensity."

"But at the same time, we also have to prepare to add a strong magnetic field repulsion method, and we can customize special magnetic field generation equipment to the high-energy institute."

……

When the research team was engaged in continuing the research, the science and technology department sent someone to find Wang Hao and talk about the order for first-order iron materials.

Two large international materials companies ordered large quantities of first-order iron materials.

Negotiations have broken down before.

Because they could not come up with 25 grams of first-order iron materials in one go, the two companies asked to buy raw materials containing first-order iron.

There were many internal meetings within the tech department, and the deal was ultimately rejected due to confidentiality concerns.

However, the rejection is also heart-wrenching!

The study of the Annihilation Force Field is nothing short of a 'Gold Swallowing Beast'.

In the past two months, he has been researching a new technology to create an annihilation force field, and nearly 200 million yuan have been quickly smashed into it.

One month, one billion dollars!

The speed at which this money is being spent is staggering.

The tech sector understands it.

The International Organization for Annihilation Theories spent nearly a year building a strong annihilation force field device and threw nearly $10 billion into it in one go.

In contrast, the monthly expenditure of one billion dollars is less than 200 million US dollars, which feels very 'saving'.

However, it's still a lot of money!

The science and technology department felt a little headache when it thought of funds, but fortunately, there was a lot of income from the sale of first-order iron materials.

"If we can win this order, there will be no shortage of funds in the coming year." There are many similar voices within the department, who think that it is okay to 'take a little risk of secrecy', and some of the basic results of the Annihilation Force Field Experimental Group will also be announced to the international community.

Anyway, the negotiations eventually broke down.

Now it's a little different.

The two companies seemed to be unwilling to be unable to buy the materials, and sent people over to negotiate larger orders, and they paid a total of $3 billion for 45 grams of raw materials of first-order iron.

That's three billion dollars!

There were many voices within the science and technology department, and there was no way to refuse directly, so they simply sent someone to Wang Hao to ask about the confidentiality of the raw materials that might be involved in selling first-order iron.

Wang Hao said very decisively, "Sell!" Why not sell! ”

It was Mr. Xu's secretary Zhang Lin who came, who was puzzled by Wang Hao's reaction and asked with some surprise, "If they get the raw materials, won't they be able to analyze the proportion of first-order iron in them?" ”

"In addition, there are many things that can be analyzed from other aspects of raw materials."

"We organized a group of experts to discuss it and came to the conclusion that if the raw materials were sold, they might be able to make an assessment of the annihilation field technology that we had."

"You might even learn that we have F-ray technology......"

Wang Hao shook his head amusedly, "You guys are thinking too much!" ”

"Even if they get the raw materials, the most they can do is estimate the strength of our Annihilation Field technology. ”

"But so what?"

"It's like we know the world's top chip technology, and we know that American has perfect nuclear-powered aircraft carrier technology, so what? Even if you know, you can't catch up for the time being. ”

"And technology isn't stagnant, it's progressing all the time."

Wang Hao said funny, "You guys, you're still too unconfident!" ”

"Technology is always breaking new ground and improving, even if they know it. By the time they catch up, we'll already have a higher level of technology. ”

Zhang Lin nodded thoughtfully.

"Have faith!" Wang Hao continued, "I guess you're still worried about F-rays, right? ”

"Yes, the F-rays are too big."

"There's no need to worry about that."

Wang Hao smiled, "If the delivery time is delayed by another two months, we can master the technology to quickly manufacture first-order iron raw materials." ”

"When the time comes, you won't need F-rays at all!"

"Is that so?"

"Of course."
