Rest is relative, motion is absolute.

Although macroscopic objects can exhibit relative rest, in the microscopic world, the particles themselves are not stationary, but are constantly in irregular motion, i.e., thermal motion.

The so-called "temperature", microscopically speaking, is also a physical quantity that indicates the intensity of the thermal motion of particles. The more intense the thermal motion of the particles that make up an object, the higher the temperature exhibited by that object.

Objects that do not have absolute zero, i.e. all microscopic particles, are in an irregular thermal motion that never stops.

Thermal motion itself is difficult to observe, but by observing Brownian motion, one can indirectly learn about the existence of thermal motion.

The so-called Brownian motion is the irregular motion of tiny particles such as some pollen and dust in a fluid.

The essence of Brownian motion is that due to the small size of dust particles, the impact of microscopic particles in all directions cannot reach equilibrium counteracting, thus showing a chaotic and irregular motion state.

It is not thermal motion, but it can reflect thermal motion.

As long as it is a fluid, it is bound to trigger Brownian motion.

But now the situation is that when pure water is given life, it can't trigger Brownian motion!

Not to mention professional scientists and engineers, anyone with some scientific knowledge will be extremely shocked when they see this.

Lin Han looked at the still and waveless starch granules in the microscope, and he was also stunned.

Could it be that the thermal movement is gone?

No, if the thermal motion disappears, the object becomes absolute zero. Obviously, this pure water is still at room temperature.

Thermal motion has not disappeared, but Brownian motion has disappeared. The greatest possibility is undoubtedly that after pure water is given vitality, its thermal motion also acquires a certain order, so that the dust particles do not undergo Brownian motion, or the movement is so small that it is impossible to observe.

Of course, there are other more fantastical possibilities, but this speculation is undoubtedly the most likely, and relatively conventional one.

So, what will be the order of the new thermal movement?

Is it spin, or is it some more complex, regular motion, or is it simply some quantum character?

Lin Han slowly withdrew part of his vitality, and the starch granules that were still in the microscope gradually showed a state of trembling.

When all the vitality is withdrawn, Brownian motion is restored, and the starch granules are bumping around like headless flies.

Lin Han leaned on his seat and fell into deep thought.

Through this experiment, it can be confirmed that the life force becomes observable after obtaining the carrier, at least indirectly by more conventional means.

In fact, if we look at the effects produced, the life force itself is observable, but the observations reflected in Brownian motion are obviously more practical in comparison.

The fact that something can be observed means that it can be included in the category of science and can be dealt with with by scientific thinking methods.

Further, it is entirely possible to build a theoretical model and quantify vitality.

Lin Han stayed alone in the basement and began to think imaginatively, speculating on the various characteristics of life force, and considering whether he needed new mathematical tools......

In the closed basement, I don't know how long it took, until a phone call came.

Because the basement is highly closed and the signal is very poor, Lin Han always puts his mobile phone in the study and makes indirect calls through the robot.

"It's Lao Song, what's the matter?"

It was Song Shuqing who called, he smiled on the phone, and said, "Ah, Xiaotong and I plan to get married in two months, I specially inform you, and ask you to be a witness or something when the time comes." ”

Lin Han was a little surprised: "So fast?"

Not long after Song Shuqing served as the head of the Qingnan Organization Department, he started a relationship with Chen Xiaosheng's sister, Chen Xiaotong, and got rid of his long-term singleness.

Although the two are very low-key, some people still know about it. After all, Song Shuqing has a good career, and Chen Xiaotong's family background is also not ordinary.

"Political marriage, of course, soon. Song Shuqing said as if he was half-joking.

As soon as the words fell, an angry female voice came from the phone: "Talking about political marriage again! Isn't it love at first sight?"

"Yes, yes, it was love at first sight...... Don't be me wrong, oops......"

As a result, in the next half minute, the phone was full of dog food, and Lin Han sweated when he heard it: "Political marriage...... Why don't I look like it?"

He has been in India some time ago, and when he returned to China, he was busy cleaning up invasive species, and he didn't know much about Song Shuqing and Chen Xiaotong.

In his impression, isn't the two a political marriage? After all, although Song Shuqing's future is bright, his family background is weaker after all.

Since Chen Xiaosheng was able to parachute in to seize the opportunity of the mayor of Qingnan county-level city, his family background is naturally first-class, and he is Song Shuqing's boss and colleague, so his sister and Song Shuqing can almost be said to be a model of political marriage.

If it is left in some stories, it may be a tragic love story.

But it seems that the two of them seem to be quite harmonious so far.

If you think about it carefully, it is actually reasonable, Song Shuqing is dignified, his ability, personality, political background, and future are all good, the woman is from everyone's background, has good looks, is knowledgeable, and has no financial difficulties, even if the two have no affection, they will not get along too badly.

When Song Shuqing's dog food finally stopped, Lin Han said, "Okay, I will definitely go over to participate then." ”

After a pause, he said again: "By the way, take this opportunity to tell you just to let you be mentally prepared...... If nothing else, there should be an order from above in a few days to make you the secretary of the county-level city in Qingnan. ”

"Me?" Song Shuqing said in amazement.

After Song Xiuming was transferred back to the capital, everyone, including Song Shuqing himself, believed that the new secretary was either Chen Xiaosheng or another one else was parachuted down.

Unexpectedly, he was actually asked to take the position.

After all, from the head of the organization department to the secretary of the county-level city, he was only promoted by one level on the surface, but when the local party congress opened and he was elected to the Standing Committee of Yunzhou City, he was promoted to the deputy city level, which was promoted by two levels, and he was in Qingnan, which is loved by everyone.

This is simply a rapid promotion, originally he was only one of the highest positions among his peers, but now I am afraid that this "one" is gone.

"Well, it just so happens that you are still Xiaosheng's brother-in-law, so he shouldn't have any opinions. ”

Song Shuqing was silent for a while: "I know." ”

The two chatted for a while, and then hung up the phone, feeling a little melancholy.

Just then, another phone turned on......
