Chapter 709: It's Raining

Catfish was not a good aquatic product when life materials were abundant in later generations, but it is different now, because this guy brings his own oil, fat and moisturizing.

Garlic roasted catfish with Su oil is a Chinese dish in Shu, and the taste is different, and everyone is addicted to eating it.

Su You hasn't been cooking for a long time, and now I feel that my skills have not returned, and I am also proud.

After another glass of toasting to everyone, Su You said to Chen Zhaoming: "Those locust powder will be sent to Zhengzhou to be used as feed additives, and the fishmeal will not be used this year and next." ”

Chen Zhaoming nodded.

Su You said again: "Si Tianjian's ceremonial platform does not necessarily have to be completed before I leave office, and the things of science and engineering must not be adulterated at all." ”

Chen Zhaoming said: "Yes, but even according to the normal construction period, it is almost the same. ”

Su You said: "What about power? Song Chenghuode, it is not very good to call the water transport instrument. My suggestion is to follow the example of the bell tower and build the platform a little higher with the potential energy of heavy objects as the driving force, which is also convenient for observing celestial bodies. ”

"Don't underestimate this, after the economic power of the Great Song Dynasty grows in the future, all the state capitals and counties, the instrument observatory, and the bell tower will be built. This is a large-scale series of projects at the national level, and it is also the best symbol of Polytechnic to improve people's lives. ”

"The miniaturization of clocks and watches, if you want to grasp it, is based on the model given to Your Majesty, and the rest is not very difficult. Then we can make a marine clock, complete it with a gyroscope, and put it on a ship, which measures longitude and is more reliable than a moon phase watch. ”

Zhang was envious: "I heard that Zhang San and Zhang Taiju have the technique of pulling stars through warp and weft, this is actually what he said, right?" There are also rumors that he has a spaceship that can haunt the seas. Others need a two-month voyage, he only needs ten days, and only he can find the sea giant Tang Shilang. With such a treasure ship, you deserve to be rich. ”

Su You thought for a moment: "Zihou, if I tell you that the earth under our feet is actually not flat; And all of us live on a giant sphere, believe it or not? ”

It was as if he had heard the funniest joke: "How is this possible? You can figure it out! Didn't all the people who lived under the ball fall...... Oh no, fall on the ...... Oh no, did it fall into the sky? Hahahaha......"

Su You clasped his hands together: "Amitabha, the donor just missed the first-class immortal fate." The warp and weft have nothing to do with you. ”

Zhang "hiccuped" and put the laughter in his stomach: "What do you mean?" ”

Chen Zhaoming explained: "The moon phase chart can determine the longitude of the ship at sea, but if we pull some parallels parallel to the equator between the two meridians, we will find that the length is actually different. ”

"The higher the latitude, the shorter the parallels between the meridians, and by the time you reach the North Pole, there is only one point left."

"Only spheres or cones have such characteristics."

"According to the idea of supervision, the Si Tianjian Geography Department cut off the distance between the places known in the Great Song Dynasty today after eliminating the influence of altitude, and then cut it off with iron wire in proportion, and then connected it to form an iron net, and we found that this iron net is really not flat, but a rough spherical surface."

"If we expand it mathematically, this sphere will form a huge sphere."

"Combined with astronomical measurements, we have now calculated that this sphere, measured by new weights and measures, has a radius of 6,370 kilometers, a surface area of 500 million square kilometers, and a distance of 20,000 kilometers from the North Pole to the South Pole."

The catfish on the chopsticks fell into the bowl: "This ...... So scary? ”

Chen Zhaoming said with a smile: "This is the theoretical basis of the longitude and latitude star pulling technique. Theoretically speaking, any point on this ball can be turned into two degrees of latitude and longitude, and we have a way to measure the latitude and longitude of the point, and then look at the latitude and longitude of the target place, we can know the direction we want to go. ”

"Mingrun is right, if you don't believe this, you can't master this technology. It's really a missed opportunity. ”

Su You said with a smile: "If you believe it, from Goryeo to Hangzhou, you can walk in a straight line on the vast sea; If you don't believe it, you can only go around in circles slowly along the land shore. ”

"So it's better to believe it or not. I don't believe that this is the exclusive stunt of the shipping division of the Sitong firm, and others can only watch the Sitong firm make a fortune. ”

Zhang was so shocked that he stammered: "Reason...... Polytechnic ...... It's come so far......"

Su You nodded: "This is still inspired by my Qingshen famous minister Chen Gong, who became obsessed with studying Yixiang ...... after he became a scholar."

Chapter knows this: "The Theory of Instrument Making"! ”

"Yes, that's it!" Su You nodded: "'The maker is still like the image', this point of view has existed since ancient times, but it has never been taken seriously. The fundamental reason for this is that the thinking ability and academic reserves of the ancients and the theoretical tools have not yet reached today's height. ”

"But now we can, we can let the theory go ahead of the curve, and then either use experiments to prove it, or lead the technology and application to keep up."

"This is the essence of 'making utensils', and it is also the most valuable part of this theory. It is the great progress of human thinking and metaphysics, and after the development to a certain height, it is inevitable that there will be practice first, and then the theory will be refined, and now there can be theory first, and theoretical research can be far ahead of practice! Be a guide to practice! ”

Zhang muttered: "Then this world has completely changed......

Su You smiled: "The world has not changed, but the way we look at the world, the way we think about the world, and the way we transform the world have begun to change gradually." ”

Zhang laughed: "Wonderful, good!" As far as Deng Wenyue and other floating villains have low knowledge, they dare to slander Mingrun as a strange skill! It's just ugly! ”

Su You said with a smile: "I don't read much, and in turn blame others for being too knowledgeable, there are many such people in the world." ”

After speaking, he spread his hands: "He is not a flat jar, can I still urge him to study?" ”

The flat can was shaving fish head soup and rice on the side, and when he heard this, he raised his head, and there were two rice grains on the corner of his mouth: "The flat can listens to Daddy's words the most." ”

Everyone laughed, Zhang Le slapped the table wildly, feeling that the atmosphere in this courtyard was much more comfortable than with the gang in Wang Anshi's mansion: "Mingrun, you have such a mouth...... It's just closed tightly on weekdays, but it's actually not much better than Zizhan! Hahaha, this witty remark is enough to be revealed! ”

Li Gonglin strictly guarded: "I want to cheat again!" ”

At this moment, a thunderclap rolled in the sky, and everyone was startled, and then their faces were happy.

Rain clouds had gathered in the air, and soon a few dull thunderclaps rang out, and the raindrops were pouring down.

"It's raining!"

Zhang was so excited that he forgot about the wine and the catfish, jumped into the rain and shouted with his hands outstretched: "It's finally raining!" ”

The residents of Bianjing City poured out of the door, crowded around the door, pulling the babies who wanted to jump into the ground, with a happy face: "It's raining!" ”

Zhao Ji was testing the box with a small key sent by the ordnance supervisor, and when he heard the thunder, he stopped, carried the box out of the side hall, and came to the bottom of the corridor.

When the rain fell, the stone steps in front of the hall were covered with wet spots, and then they became a thin surface of water reflecting the dark blue light, and countless droplets of water jumped brightly on it.

The glazed tile roof began to drip water droplets, and soon it merged into a water curtain, just like the tears that flowed involuntarily in Zhao Ji's eyes: "It's raining......"

Wang Anshi was writing a statement when he was interrupted by the sudden sound of a thunderstorm.

He listened intently for a while, smiled and added the last sentence to his notice, then put the pen down, pushed open the window of the study, and let the moisture be carried into the small study by the wind.

It's raining.

……

The bell of the bell tower rang faintly ten times, and the flat jar was already asleep.

Shi Wei pillowed on Su You's shoulder: "Brother Xiaoyou, are you going to Beijing again?" ”

Su You said: "Traveling in the four seas, this is an inevitable thing. ”

Shi Wei tightened Su You's neck: "I really can't bear you." ”

Su You was a little stunned: "What do you mean?" Of course we're together, and Hachiko, a flat can. ”

Shi Wei blushed: "No, at least not now, at least I have to wait for a few more months." ”

Su You asked, "Is it the charity side, or is the Heavenly Master's Mansion unable to leave for a while?" ”

Shi Wei shook her head: "No, I didn't come this month, I may have it." ”
