Chapter 773 The Seed of Science

The wind-powered waterwheel finally adopts a vertical-axis windmill with a shaft height of [-] feet and a diameter of [-] feet. It can accommodate nine-blade sails. The way of hanging the sails refers to the way of hanging sails. It was determined after repeated tests and comparisons. The key is to allow one side of the sail to bear the force.When turned to the other side, it will shrink against the force of the wind, so as to ensure that the wind wheel always rotates against the wind without being resisted by the wind.

The bottom of the vertical shaft is equipped with a "windmill ring", that is, a horizontal large gear with a total of 73 teeth. This so-called gear is very different from Ye Chen's imagination, similar to the one with a handle on an old-fashioned ship. Steering wheel, but the disc is bigger, and there are more handles as "teeth".

"Bite" with this big gear is a vertical gear with a total of 21 teeth. Naturally, the shape is the same, but it is much smaller.The large gear rotates in the horizontal direction under the drive of the vertical shaft windmill, and drives the vertical gear to rotate in the vertical direction.

After Ye Chen looked at it, he found that although this primitive gear looks rough and must consume a lot of power when turning, it is very practical. At least it is not a problem to drive this primitive waterwheel. After all, it involves technical level, even if the gear is advanced However, the waterwheel itself may not be able to withstand higher speeds.

The vertical gear is connected to a horizontal shaft, and the other end of the horizontal shaft is connected to the waterwheel. There is a large runner, that is, the "water head", which has nineteen teeth and is inlaid with wooden ones, which are closer to crawlers. The inner side of the chain is a groove interlocked with the gear teeth, and the outer side is equipped with a bucket. When the gear rotates, the wooden chain is driven, and the bucket lifts the water.

It looks very rough, and because of this, Ye Chen can deduce from the composition that this wind-powered waterwheel can operate, and there were no major accidents during the manufacturing process.Just because the waterwheel needs to be elevated, it was a bit troublesome to install, but it was finally resolved.

By the side of the Qin Canal, which is as wide as a small river, the first wind-powered waterwheel in Xiangfu Kingdom, named Dali No. [-] by Ye Chen, stands tall. It's more than one foot long, and it's more than four feet tall. It's as high as a two- or three-story building, and it's very eye-catching in the wilderness.

The wind by the river was very strong. After the nine sails were set up, driven by the force of the wind, the wind wheel trembled slightly and started to rotate slowly.The creaking sound of the vertical shaft and the friction of the gears was very pleasant to the ears of Ye Chen, the craftsmen, and the people of Dangxiang County who came to observe.

Driven by the gears of the windmill, the horizontal shaft of the waterwheel also began to rotate slowly with the wooden chain. The wooden barrel on the wooden chain sank into the water, and when it rose out of the water, it was already half filled with water.

The barrel filled with water was lifted higher and higher.At the water wheel, the wooden chain began to bend, the wooden barrel tilted, and the water contained in it flowed out along the mouth of the barrel and fell into the pool under the water wheel.

The pool under the water wheel is not big, and there is no water storage. The water that falls into the pool quickly flows down the wooden sink, flows into the ditch below, and is sent to various places.

Kou Zhun looked at the amount of water, quickly estimated it, and said happily: "Your Majesty, at this speed, it is enough to irrigate [-] acres of fields a day. In the eight counties of Hetao, each county only needs to build ten wind-powered waterwheels. It is enough to turn all the dry land into paddy fields, and nearly half of them can be converted into rice fields."

"This is just the beginning." Tian Jiumi watched as the ditches leading to the fields had been dug, and the river flowed forward along the ditch. Presumably, by tomorrow, some fields would be soaked in water for a while. After a while, empty the water, then soak it with water, and repeat it again and again.It is washing soda.After the soil has been washed with alkali, the salinity and alkali content will be greatly reduced, and some manure fertilizers can be applied to improve the soil fertility. After a few years, it will become a fertile field.

Xiangfu College has gradually entered the normal track, and the problem of lack of lecturers and professors has gradually eased, let alone worrying about not being able to recruit students.The whole college now wears uniform clothes, light blue linen, linen is very cheap, but blue dye is very expensive, this was once strongly opposed by the Minister of the Ministry of Households, Jia Xian, and it is still what he has been criticizing. There is no need to dye the clothes light blue, you can dye them blue, white, or black, and you can save at least half of the money.But in the end, due to the strong demands of the college students and Ye Chen's purpose of highlighting the status of the college students, this matter could not be changed in the end.

In the early morning, when the bell rang, all the students came to the kitchen with a tin bucket to carry hot water for washing, no matter who they were, no matter where they came from.Because of Ye Chen's attention, and the fact that all the officials of the imperial court are "visiting professors" of the college, Xiangfu Kingdom sent all of his children and grandchildren who still meet the recruitment age and conditions to the school. Xiangfu Academy takes part in the assessment, and then enters to study.Therefore, strictly counting, at least one-third of the first batch of students in Xiangfu College are the children of officials, and many of them are dudes.

At this time, everyone was carrying their own keg while discussing what to have for breakfast later, while thinking about today's lesson.From ancient times to the present, school meals have never been delicious, and Xiangfu Academy is no exception. Of course, there are also big fish and big meat, which are delicious food in the eyes of ordinary people. I don't like to eat this kind of big pot meal. Most of them eat in restaurants near the college.However, in the eyes of some poor students, meat such as braised pork, chicken legs and duck wings, which are much cheaper than outside the school, is relatively famous and frequented.Even some of them are not college students. Poor scholars or ordinary people who come to take classes can buy a fatty, red braised pork or chicken legs and duck wings in the cafeteria for two pennies. The smell is intoxicating. Surprised by the supreme food.Some are still reluctant to eat, so they pack them in bamboo lunch boxes and take them home for the whole family to enjoy.

Ye Chen returned to Xiajing from a private visit to the Hetao eight counties microservices, passing by Xiangfu College, so excited, he planned to visit Xiangfu College.

It was Si time when Ye Chen arrived, and it was the time for class. There were very few people in the college, and because it was a private visit in a micro-service, Ye Chen only brought Lian Jicheng into the college, so no one noticed for a while.Kou Zhun stayed in his Dangxiang County and continued to be the county magistrate. The goal Ye Chen gave him was to turn Dangxiang County into a big Dangxiang prefecture. There should be at least [-] Dangxiang people and at least [-] Han people living under his rule.But Tian Jiumi is busy with his own affairs, and now the Minister of Agriculture is vacant. He is the left servant of the Ministry of Agriculture, and he is responsible for the responsibility of the Minister. It's all about his Ministry of Agriculture.In addition, the prefectures and counties of the imperial court directly purchased surplus grain from the people at a price higher than the market price to fill the official warehouse. The purpose was saved.

"Everyone must first understand that the subject of geography offered by our Xiangfu College is quite different from the word 'geography' mentioned in previous books. The word "geography" first appeared in China's "Book of Changes", in fact it is Another name for 'Feng Shui', ha ha! Speaking of this, several lecturers in our school's mathematics department are very clear about this! I discussed it with them a few days ago. Okay, let's get down to business, before this' Geography' is the theory that ancient scholars studied the way of "harmony between man and nature" acting on the surface of the earth or the internal system of the earth. At present, there are a large number of ancient books handed down from generation to generation, all named "geography", such as "Geography Cutting Jade Axe", "Geography Eating Sugarcane "Record", "Five Judgments of Geography", "Four Marbles of Geography", "Geography Nangjin" and other ancient books are all famous works of Fengshui. The "geography" here is another name for Fengshui. And the "geography" subject opened by our college It was named by His Majesty Xiang Fu Kingdom himself, which naturally has a profound meaning, and it has nothing to do with Feng Shui. What we talk about in geography is the study of various natural and human phenomena in the geographical environment on the surface of the earth, as well as The disciplines of their interrelationships. Therefore, geography is a comprehensive basic discipline. We said earlier that the land we live in is not the so-called round sky..."

The college is open to the public, and as a result of those newly opened courses, there are huge crowds of people who come to observe them. If you come later, there is absolutely no place to stand.Ye Chen and Lian Jicheng were in a classroom surrounded by people inside and outside the corridor, quietly listening to the situation inside. Through the window, Ye Chen found that the students were listening very carefully, and their faces were full of exploration of the world. Novelty and desire, Ye Chen could not help showing a smile on his face, turned and left, ready to listen to other classes.

Ye Chen didn't know that quite a few of those who came to attend the lecture were very dissatisfied with what was being said, and even strongly opposed it. They especially came to the college to argue with the lecturers and professors.Compared with the obscure and difficult mathematics, chemistry, physics, and biology, geography is the most provoking scholar from all over the country, and even many students from colleges come to argue, not to mention the geography course of Xiangfu College. Negating the long-standing statement that the sky is round and the earth is round has caused countless disputes.

In general, the success of setting up Xiangfu Academy is beyond Ye Chen's imagination. He seems to have seen the scene of the college being crowded with students taking the registration exam in the second year...

"But how long can this kind of enthusiasm be supported in a society where learning and excellence can lead to officials? Without my full support and promotion, many people can see that I value it, otherwise I am afraid there will be no such effect."

"So, since I have planted the seeds of science, I have to be a good cultivator, and to do this, I have to completely change the status quo of academics and excellent officials. After all, only a group of excellent and clean officials, Politicians can at most make the Xiangfu country peaceful and peaceful, and may be able to solve the problem of food and clothing for the people, but it is difficult to make the productivity of this country truly progress and become stronger, let alone let all the people go straight to a well-off life, or even become rich. Therefore, It is a general trend to vigorously enhance the status of scientific research workers and even businessmen who are mainly artisans. Only in this way can the seeds of science grow vigorously and grow into a towering tree after they germinate."
