Chapter 5080: Do an experiment

Li Chunfeng's hands were very stable, and the iron block was gently placed into the basin and quickly sinking to the bottom. The water in the basin overflowed and spilled into the stone trough, and no ripples appeared on the water surface.

Then quickly put the copper basin to one side, use both hands to lift the muscles of the arm, tilt the stone trough, and just as the water overflowed from the copper basin was poured into another small copper basin.

Lu Cai hesitated for a moment and asked carefully: "Why is it so hard to use a stone trough? It should be fine to get a larger copper basin."

Anyway, it's just used to hold it. For overflowing water, you can just put a large basin in a small basin. Why do you have to use a stone trough worth dozens of kilograms?

Fu Renjun on the side said leisurely: "The entire Taishi Bureau has only two copper basins."

Lu Cai widened his eyes: "..."

Then he looked around, the most mysterious thing in the entire imperial city. The Taishi Bureau, which is so poor in the yamen, and countless powerful and nobles, is so poor?

He said in surprise: "Not mentioning the grants from the court, whether it was Yuan Tiangang back then or Li Chunfeng now, he would charge hundreds or thousands of chunks of stagnation for others... Why does it even cost him? You Taoist priests can't afford to buy a copper basin?"

You Taoist priests are not Qingliu, so you don't need to be thrifty and deliberately pretend to be poor to gain reputation, right?

Fu Renjun stroked his beard and sighed: "The Taishi Bureau has a lot of investment, but it costs a lot! Not to mention anything else, just to update the stargazing equipment, I bought more telescopes from the foundry bureau, and the cost was a sky-high price. Ah! Not to mention building a new observatory, the Taishi Bureau is almost ready to be a pants! "

"I have heard of the telescope. It is said that the stars in the sky are as close as they are, but they have never been I can see...but this is for the court. Doesn't the Ministry of Civil Affairs allocate funds?"

When talking about this, Fu Renjun was full of anger and stared at him: "The old thief said that the sun and moon flow and the stars move, all of them have a number of days. It will not disappear there, and you can't see any Zi, Chou, Mao and You again. The national treasury has its own value, so how can you spend such false things? You are simply not a son of man! ”


He and Tang Jian are of the same generation, and their qualifications are not inferior to each other, so he is extremely unpolite in his words.

Lu Cai nodded.

The reason why Tang Jian said this is actually the root cause of the Censorate. Since the publication of the book "Mathematics", many algorithms in it shocked the world, making all measurements and calculations related to it have made great progress, and naturally, it also It affected the Taishi Bureau, which is responsible for stargazing and mapping and calendar preparation.

The Taishi Bureau uses the latest algorithm to accurately calculate the laws of the movement of many celestial bodies, and predicts solar and lunar eclipses with extreme accuracy. This is also the reason why Fu Renjun still lives in the Taishi Bureau even though he had retired. He created the The "Wuyin Calendar" has many problems caused by algorithm errors, and now it is doing its best to change it.

The consequence of this incident was the complete collapse of the Confucian theory of "resonance between heaven and man".

The movement of celestial bodies has their own laws, and they remain unchanged throughout the ages. Therefore, regardless of whether the king is unethical or the ministers are treacherous, solar and lunar eclipses will definitely happen when they should occur. Li Chunfeng even has been doing so for decades. Observing wind power, it was found that rain, snow, thunder and lightning were not caused by the gods' anger. They all had their own internal laws, and they could be predicted in advance...

As a result, the status of the Taishi Bureau plummeted.

The words of the Ministry of Civil Affairs also make sense: Since the movement of the sun, moon and stars has its own rules, when will it not be possible to observe? Why bother to spend money and money to do those useless work?

Since the solar eclipse will occur at the specified time, what's the use if you measure this time a hundred years in advance?

Can you prevent solar eclipse from happening?

On the other hand, Li Chunfeng, who was concentrating on the experiment, focused on his mind, ignored the talk of the two old Taoists, placed the small copper basin containing the overflowing water in the weighing plate, weighed it carefully, and then made it with a charcoal strip on white paper. The record was recorded, and then the water was poured out, the weight of the small copper basin was weighed, and the calculation was performed on the paper for a moment, and the total number was used to subtract the weight of the small copper basin to obtain the weight of the overflowing water.

Then weigh the weight of the iron block.

Then put down the copper scale, wiped your hands, picked up a book of "Physics" with edge burrs, turned to the page of "Specific Gravity", compared it, and exclaimed: "It's true!" >
The two old Taoists were immediately attracted, and Lu Cai hurriedly asked, "What's the case?"

Li Chunfeng said, "Physics believes that all objects have different 'comparison' due to the different materials. , and set the proportion of the most common water to one, based on this basis, the proportion of the iron is 7.8."

Lu Cai was speechless: "Are you slandering me for being ignorant? It's not a boast about reading a lot of books. Of course I have read "Physics", and I know the term "particularity"!"

Li Chunfeng rubbed his hands, A little embarrassed: "I'm afraid you don't have time, so I haven't seen it!"

He handed the paper to Lu Cai: "The weight of the iron block is two and a half pounds, and the weight of the overflowing water is Three liang, according to the 'buoyancy principle', objects immersed in liquid are floating upwards The buoyancy is equal to the weight of the liquid discharged by the object... Therefore, the buoyancy received by the iron block is two and a half pounds. If an object wants to float on the water, it must be more buoyancy received by the iron block... It is smaller than its own weight, so it sinks to the bottom."

After speaking, he ignored the two people watching the records on the paper, scooped water into the large copper basin again, picked up another wooden block and repeated the experiment...< br>
Most of the wooden blocks were sinking into the water, floating and sinking.

Then weigh the weight of the overflowing water and the weight of the wooden block...

Take the paper from Lu Cai and record: The weight of the wooden block is one pound and two ounces, and the weight of the overflowing water is one and a half pounds and a half pounds. …

Conclusion: The buoyancy received by the wooden block is greater than its own weight, so it floats on the water surface and will not sink to the bottom.

Li Chunfeng let out a sigh and exclaimed: "Fang Erlang is truly a gift from heaven. This principle exists in the world for millions of years, living with the heaven and earth, and living with the sun and the moon, but no one has ever been around since ancient times These common phenomena can be described in such precise principles! ”

Lu Cai and Fu Ren both fell into deep thought.

The former said after a while: "It's really amazing, but how do you apply this principle?"

Li Chunfeng picked up the large copper basin and put it on the scale. After weighing it, he threw the copper basin into the lotus pond. Smashed a few lotus leaves and swayed on the water.

He pointed to the floating copper basin: "This copper basin weighs two kilograms and three liang, which is almost the same as that piece of iron, but it floats on the water surface and does not sink to the bottom. Why?"

Lu Cai and Fu Renjun both grabbed their beards together. Both of them were extremely intelligent. After a while, they came to the conclusion and said in unison: "Because the shapes are different!"

The difference between iron blocks and copper basins is only the shape. That's it.

But it is this difference that leads to a completely different result - the iron block sinks to the bottom and the copper basin floats.

No mistakes, one poem, one post, one content, one in 6, one book, one bar, one read!

According to the "buoyancy principle", the conclusion is that the copper basin has a greater buoyancy than the iron block...

...

After that, Fu Renjun and Lu Cai also had it. They started experimenting separately and exchanged their opinions on the "principle of buoyancy". At noon, the little Taoist priest came from the back hall to greet a few people for meals, then washed his hands and went to the canteen behind for meals.

Lu Cai was so good at drinking, and Fu Renjun and Li Chunfeng also refused to accept everyone. They just whispered a few simple but exquisite side dishes.

Li Chunfeng took a sip of wine and said with a smile: "Taichang is proficient in the art of yin and yang. Why not calculate it here and calculate what my fortune is?"

The so-called "mortality" ", is a kind of Yin and Yang numerology, a branch of the eight characters of numerology, which includes a person's wealth, blessings, official career and even destiny. The diviner can use various means to predict a person's good or bad fortune in his life.

Lu Cai scoffed at this: "What is the relationship between a person's misfortune, good fortune, nobility, longevity and life? Now there are also the same year and the same fortune, but the difference between the noble and the low; the same life and fetus, and the death of the young and old is even more common. Different. If the saying "Lu Ming" is true, what explanation can be made of this?"

Fu Renjun also said: "In "Lunheng", there is also "knowing the bone body and knowing the fortune, and seeing the fortune And the words of "Knowing the Bone Body" can be seen that "Lu Ming" can predict and calculate."

The theory of "Lu Ming" has a long history and has spread far-reachingly. Most people in the world believe it as true. Many great scholars of ancient and modern times have explained it one after another, making its influence more widespread.

Lu Cai saw Li Chunfeng pouring wine for him, nodded and thanked him, and said with a smile: "A person who divinates is a master of fortune and destiny to please others' hearts, and he can speak misfortunes and good fortune to do everything he can. That's all."

After drinking a sip of wine, the conversation was very good, and then continued, "You have probably read the Luming Book. Many of the books have said that Qin Shihuang is "a man with no beginning and no end, and he is old and no longer auspicious." However, I believe that Records of the Grand Historian, it is found that Qin Shihuang clearly has the beginning but no end , the old man is more evil, but he lived only fifty years old. I also studied the lives of Emperor Wu of Han, Emperor Xiaowen of Wei, Emperor Gaozu of Song Dynasty and others in the Southern Dynasty, and found that the theory of fortune and life is nothing but nonsense and deceptive. "

Yin and Yang, numerology, astrology, etc. are all derived from Taoist doctrines. Although Fu Renjun and Li Chunfeng were not descendants of this Tao, they also heard about it and knew a little about it. Seeing Lu Cai abandoned the "Lu Mingshu" If you are too old and disdainful, you are very interested.

Because from these words, we can see Lu Cai's thoughts, this is an "atheist"!

It's so deviant!

Fu Renjun asked, "In this way, are the so-called Yin and Yang and Five Elements, Geometric Feng Shui all false things?"

Lu Cai shook his head: "The sayings of ghosts and gods are illusory, but if you believe in them, you will have them. If you don’t believe it, you won’t have it. But the five elements are different. The movement of heaven and earth and the alternation of yin and yang is visible to the naked eye and feeling it personally. How can I refute it together? Besides, although I do not believe in ghosts, gods, fortune, and fate, I believe that 'everyone has a fate' It's just that this 'life' is not born That is the fixed number, but changes are happening anytime and anywhere."

Another sip of wine, he said leisurely: "Just accumulate good fortune and happiness, not the auspiciousness of wealth; if you accumulate evil and disaster, how can you Due to the reality of robbery and killing. The emperor has no relatives and always has good people. The response of good fortune and good fortune is still the same. "

Family who accumulates good deeds will bring good fortune, which does not depend on the protection of "Jianlu" ;And families that accumulate evil deeds will bring disaster, and this is not because their lives are "robbery and killing".

"Jianlu" is the auspicious star in "Lu Ming Shu", and "Jizai" is the auspicious star in "Lu Ming Shu".

The retribution of good and evil is a natural law and has nothing to do with numerology.

Good deeds will bring blessings, and evil deeds will bring disasters. This is the inevitable result, not the role of the good and bad stars described in numerology. A family that accumulates good deeds will surely have good fortune.
