If the Pearl River water system is compared to a long dragon, then the north and south Panjiang rivers and the Hongshui River are the dragon's legs and the dragon's tail.././The dragon's feet are the north and south Panjiang rivers, which converge at the Sanjiangkou to form the dragon's tail - the Hongshui River.
They first went down the Nanpan River. This section of the river has steep beaches, fast currents, and shallow water, making it difficult for larger boats to navigate. In order to solve these problems, Shen Kuo proposed that in places with rapid currents or shallow canal water,
Set up a 'steep gate'... divide the channel into several sections, install gates, and open the gate between the two sections. The water level in the two sections will rise and fall to the same level, making it easier for ships to navigate.
Shen Kuo deserves to be regarded as a scientific genius who only appears once in a thousand years. Although Chen Ke coincides with him, he cannot use his own mathematical methods such as "gap accumulation" and "huiyuan" to accurately calculate the river course.
Data necessary for engineering such as terrain and level height.
Although Chen Ke had thousands of years of experience more than Shen Kuo, and was a top student in mathematics, physics, and chemistry when he was in school, it still took him a long time to understand that the so-called "gap product technique" was the summation of second-order arithmetic series.
Method. And the 'Method of Circles' is a method of finding the chord and arc length of the arc given the diameter of the circle and the height of the arc.
It would take hundreds of years for Europeans to master this method, and it is unprecedented in China!
No one knows how this guy figured it out. But Chen Ke is no longer amazed, because in the past six months of cooperation, he has long been used to seeing any technical problems, and he can always solve them in front of this monster. And this guy is not like the world.
The difference is that while others rely on experience to solve problems, he relies on mathematics and logic!
Moreover, this guy's extensive knowledge is astonishing. He has deep interest and considerable attainments in astronomy, geography, mathematics, physics, chemistry, geology, meteorology, geography, agriculture and medicine... Considering that he is only twenty-six years old
His age shows how terrifying this guy is.
If you want to ask who is the most talented person in the Song Dynasty, Chen Ke will definitely choose this guy instead of his uncle. He even thought for a time that the other person was a time traveler like himself. And he was a doctor of science who traveled through time. He even tried to test it several times,
This made Shen Kuo confused - he was an out-and-out Song Dynasty person.
Well, I have to admit it. Some people are geniuses, and a genius only emerges once in a thousand years. What reason do you think Chen Ke has for not protecting him? Of course, there is another terrifying science expert Su Song...
From the first day they arrived at the military camp, Chen Ke announced that they enjoyed the highest standard of security, second only to Commander Fan Zhen and higher than himself. The same was true for the treatment. Many people, including themselves, did not understand
, the dignified champion of the Song Dynasty and the deputy commander-in-chief of tens of thousands of troops, why did he pay so much attention to these two inconspicuous officials?
Su Song is easier to understand. Although he is a casual official, he is still a liar, and his future success is unknown. As for Shen Kuo, it is really puzzling... You know, this guy is not even a Jinshi, he relies on his father
En Yin only entered the officialdom.
But this is a world of imperial examinations. In the officialdom, Jinshi is king. Even if Confucius failed to pass the examination, no one would admit that he had real talent and learning. Those second-generation officials who relied on favors to enter the officialdom were also despised and ostracized.
.
It would be better if the father was in a high position or the lingering shadow is still there. I am afraid that like Shen Kuo, the tea will be cold after the death of the father. Then it is true that grandma does not care and uncle does not love. No matter how hard you work and have outstanding political achievements, your boss will turn a blind eye. There is only one time.
. Only the boss will see him, that is, if something goes wrong, someone will take the blame...
Speaking of these years, Shen Kuo shed tears of bitterness and couldn't stop talking for ten days. This time when he received the order to go south to join the army, he naturally thought that it was another hard job that the non-commissioned officers were unwilling to accept, and finally it fell on him. Shen Kuo
He secretly said that he was unlucky, but the military orders were like mountains, and he didn't dare to disobey them even if he had only three courages.
I had no choice but to say goodbye to my wife and children, arrange my funeral arrangements, and head south with a gloomy heart. Who would have expected that when I arrived at the military camp, I would receive such high-level courtesy? How could Shen Kuo not dare to touch him?
Although the intellectual's aloofness made him unwilling to express anything in person, all the tasks assigned to him by Chen Ke were overfulfilled. He even took the initiative to solve problems that Chen Ke had not thought of, which already showed his attitude.
.
And as the days of contact became longer and longer, Shen Kuo began to admire this new top scholar more and more.
The only thing that scientists can admire is another equally outstanding scientist. Although Chen Ke is far from being called a scientist, his insights that transcend a thousand years can only be appreciated by minds that transcend the times. For example, Su Shi admires Chen Ke's
He knew everything, but his romantic brain was destined not to pursue boring truths. Therefore, Chen Ke never deliberately introduced to Su Shi the knowledge that transcended the times.
Only Shen Kuo can truly understand, appreciate, and accept his knowledge. And Shen Kuo's discoveries and insights can only be truly understood, appreciated, and accepted by Chen Ke.
In any case, the conversations between the two became more and more extensive and in-depth. They often started with small talk, and gradually others could no longer get in the conversation and could only listen to the two of them talking about the Book of Heaven...
For example, Chen Ke invented cement and concrete, and everyone's attention was focused on its impact on war and engineering. Shen Kuo said that with cement, people no longer need to cut down a large number of trees, which is a good thing that will last forever.
People were puzzled and asked whether cutting down trees could affect generations to come. Chen Ke gave the affirmative. He started with the fact that trees can retain water and soil and change the climate. He also mentioned that excessive cutting down of trees will lead to soil erosion, barren land, environmental deterioration, and ultimately no
Suitable for human habitation.
This was strongly agreed by Shen Kuo. He told everyone that based on various historical records, it can be concluded that the Loess Plateau was originally densely forested and grassy, with herds of wild deer. This situation began to deteriorate during the Qin and Han Dynasties, but the change was not significant.
Because according to the "Book of Mountains and Seas", Baiyu Mountain has "many pines and cypresses on the top and many oaks and sandalwood on the bottom". Li Daoyuan of the Northern Wei Dynasty also recorded in his book "Shui Jing Zhu" that there was still a "grove of elms and willows" near Yulin.
It shows that the southern boundary of the grassland belt should be north of the line between Huanxian and Yulin, and the south should be the forest.
During the Tang and Song Dynasties, the forests on the Loess Plateau decreased rapidly, and desertification was so severe that "thousands of miles north of Huanqing are barren." So where did the green forests on the loess go? One was the dynasty that built palaces and established its capital in Guanzhong
The wood was taken from the nearest place; the second was felled by the people for construction and fuel. But the most serious act of destruction was the construction of military fortresses. This dynasty had a long-term confrontation with Xixia. Over the decades, nearly 10,000 fortresses were overhauled, and each fort was repaired.
Destroy a forest!
If cement is promoted, the few remaining forests on the Loess Plateau can finally be preserved. Trees can be slowly replanted in the future, and the ancient lush forests and beautiful mountains and rivers may be restored!
Shen Kuo's ecological concept was not inspired by Chen Ke's cement. In fact, before that, he had written to the court to collect charcoal on a large scale as the main fuel for the people and the court. He also read in the book that "Gao
"There is fat and water in Nu County, which can be burned." I once took advantage of the Dingyou period to personally go to the border to inspect and found a brown liquid. The locals called it "Shiqi" or "Shizhi", and used it to cook, cook, and light lamps.
and heating. Shen Kuo gave this liquid a new name, petroleum... He had long wanted to use coal and petroleum instead of pine wood as fuel. He said that trees should never be cut down unless necessary, especially ancient forests.
Don’t even destroy it!
In Chen Ke's opinion, his view is absolutely correct, but others don't care...
Therefore, this is not the so-called high mountains and flowing water, but the loneliness of the prophet.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
During the inspection of Nanpan River and Hongshui River, the two of them always looked at the stars together on clear nights... This kind of behavior that made Liu Yue'e shudder had nothing to do with it, but because looking up at the stars here was better than looking up at the mainland.
Be clearer.
Previously, they used small hole imaging experiments to prove to people that light propagates in a straight line. They also used this principle to explain the causes of solar and lunar eclipses and the laws of the moon's phases. In order to explain this situation clearly to everyone, Shen Kuo also
A simulation experiment was designed... using a projectile, half of its surface was coated with white powder to represent the sunny side. When viewed from the side, the powder looks like a hook, and when viewed from the opposite direction, it appears to be a perfect circle. Chen Ke made a larger model, and also
Use this indoor demonstration method to show everyone the movements of the sun, moon, stars, and celestial bodies.
Hearing him say that there is a sphere under his feet, the moon revolves around the earth, and the earth, wood, water, fire, and Venus revolve around the sun... Although no one had the nerve to laugh at Chen Ke because of his identity, everyone still used the euphemistic method of praising his imagination.
express their attitude.
Chen Ke couldn't come up with an intuitive way to make them believe it, so he could only laugh it off. However, Shen Kuo was very interested in his statement and believed that this hypothesis could solve his long-standing doubts.
Moreover, Chen Ke gave him a telescope that could shorten the distance to the sky. The conditions for stargazing were so good that Shen Kuo was not willing to waste a moment. Whenever there were starry nights, he would aim the telescope.
The deep and distant sky is observed night after night regardless of fatigue and coldness.
Although this was just an ordinary telescope, it had already lifted the mysterious veil of the night sky for Shen Kuo... He saw that the 'Moon Palace' on the moon was actually high mountains and low depressions. He also saw the bright and dark colors on the moon.
By moving some parts, we discovered that the moon itself does not emit light; the moon's light comes from the sun.
He also observed the satellites orbiting Jupiter, which initially supported Chen Ke's statement.
Chen Ke is so shameless. He has been tinkering with the telescope for almost ten years. Apart from dedicating it to Marshal Di, it was just used to look at the scenery and please his wife. It was basically a waste. But once this thing got into the hands of Shen Kuo
, it becomes an artifact that reveals the secrets of the universe. Why do you think the gap between people is so big?
Of course, the magnification of this telescope was too small, which greatly limited Shen Kuo's observations. Chen Ke promised that after returning to Beijing, he would build a large astronomical telescope for him so that he could reveal the secrets of the sky! (This site.com Your support
