Tiantang Splendid

Chapter 790 This is Black Technology

"Han Shu Lv Li Zhi" said when talking about length: "Those who measure are points, inches, feet, feet, and quotations, so the length is also measured....One is one point, ten is an inch, and ten inches is a ruler. Ten feet is the zhang, ten zhang is the guide, and five times the trial."

The five units of length mentioned here are points, inches, feet, feet, and quotations, but there are no miles...

Of course, the length of miles is not mentioned, not because there is no length of miles, but because of the lack of records for various reasons.

"Hanshu Shihuozhi [-]" said: "The way of rationalizing the people is based on land. Therefore, it is necessary to establish a step and a mu to correct its classic boundary. Six feet is a step, a hundred steps are a mu, a hundred mu is a husband, and a husband The third is the house, the third is the liter, and the well is one mile wide, it is for the nine husbands."

From this record, we can know that the well is one mile square, and the 800 mu of cultivated land cultivated by Jiufu is [-] mile and [-] paces on each side.One step is six feet, and three hundred steps in one mile is [-] feet.

The construction ruler used by the Ministry of Industry in the past dynasties after the Tang Dynasty is also called the Buchi, and the common name is the Luban ruler, also known as the Dachi.An important feature of this kind of ruler is that one step is five feet.The length of one chi is 1 chi of Qin chi. "Weights and Measures" in the volume of "Continued Literature General Research" contains: "The merchant ruler is the curved ruler used by carpenters today. It was passed down from Lu Ban to the Tang Dynasty, and the Tang people called it a large ruler. It has been used since the Tang Dynasty. The name builds the ruler. The ancient so-called turning ruler."

Since the building ruler is the scale used by the Ministry of Industry in the past dynasties, it has strong credibility and is widely used.With the development of society, it is a reasonable choice to calculate the length of the building with a ruler.

When the weights and measures were re-established, it was clearly stipulated that the system of li was: "Five feet are one step, two steps are one zhang, ten feet are one lead, and eighteen leads are one mile." That was already a matter of the Guangxu period of the Qing Dynasty...

There is no unified, standardized, scientific and reasonable weights and measures, which is a major drawback restricting the development of industry and natural science.Fang Jun once proposed a "world standard" in the Ministry of Industry, but with his departure from the Ministry of Industry, this idea died.

But this idea seems to have to be put on the agenda, otherwise the length of "li" alone will make Fang Jun dizzy, and he still hasn't figured it out...

Su Dingfang was speechless: "How can you run so fast?"

Liang Renfang had obviously heard of Su Dingfang's name, and admired the general who swept across Mobei, so he said respectfully: "Su Dudu doesn't know, the biggest advantage of this ship is not its speed, but his sails! This whole set of sails is designed by the chief steward, it is simply ingenious, and with this kind of sails, it can sail regardless of the wind or the wind!"

Fang Jun smiled and said nothing, this has nothing to do with sails, it is just a simple principle of aerodynamics, but it is such a simple principle of "increasing the fluid velocity, the pressure will decrease", which I explained to Liang Renfang at the beginning Fang Jun couldn't explain it for a long time, and finally Fang Jun, who was completely devoted to "science popularization", simply ordered directly-you don't need to know why, just do it!
Simple and crude, but very useful.

Liu Renyuan on the side widened his eyes and said in disbelief: "Don't talk about it, you can wet your trousers when you pee against the wind. Wouldn't the boat be blown backwards against the wind?"

In his cognition, ships mainly rely on sails to sail on the sea, and the wind blows the sails to bring power and push the ship forward.But if it is facing the wind, the force is reversed, how can it be possible to move forward?
Liang Renfang was polite to Su Dingfang, it was because Su Dingfang was the general who broke the Turkic tooth tent, although the Lord did not show that his position was not high, but his achievements were there, so he was not so polite when facing Liu Renyuan.

Who is this big and thick guy?never seen it……

Therefore, Liang Renfang said unceremoniously: "Everything in the world has its own truth, so we must study things to learn more. Sand and gravel can be turned into crystal clear glass, ore can be turned into sharp and tough weapons, water can be turned into ice, and clouds can be melted." Rain, why can't ships sail against the wind?"

"This..." Liu Renyuan was so choked that he rolled his eyes, but he couldn't think of a rebuttal.

Fang Jun pointed to the sailboat in the dock and said, "What's the point of arguing? The boat is there, let's take it out for a walk, and the truth will come to light? But since Xiaowei Liu didn't believe it, Mr. Liang made an oath, and neither of them was convinced. How about a bet?"

This is black technology, today I will definitely hack Liu Renyuan.

Su Dingfang nodded immediately: "This is fine."

Those who watch the excitement are naturally not afraid of big things...

Pei Xingjian chuckled: "Gambling money hurts feelings, and it's a bit vulgar. Why don't you just bet on a roasted whole lamb, and whoever loses will be responsible for the fire and barbecue tonight, and the rest will sit back and enjoy the profits, drink and have fun together, how about it?"

Liu Rengui remained expressionless: "Someone agrees."

Liu Renyuan stared in displeasure and said, "Why do you expect XX to lose? XX doesn't believe it yet. If the sailboat can sail against the wind, why not say that the river flows backwards and the sun rises in the west? Just bet!"

Fang Jun smiled and asked Liang Renfang: "What is Master Liang's intention?"

Nonsense, Liang Renfang would refuse something that was clearly a certainty?

So Liang Renfang put on an old face that was three points darker than Fang Jun's, and stretched out his stubby fingers covered with calluses: "You need to roast two."

Liu Renyuan was so angry that he yelled: "Old man, don't be arrogant. If we really can sail against the wind, then our royal navy will be invincible on the sea with such a magic weapon. What if I roast a sheep for you for a lifetime? Hugh? Let's show off your tongue here, board the ship and raise the sails quickly, and the winner will be judged!"

Hearing this, Liang Ren just changed his disdain for Liu Renyuan, and stretched out his thumb to praise: "As expected of a hero in the army, in order to have sharp artifacts in the army, he will be invincible on the battlefield, and no punishment will be given." They are all willing to bear it, worthy of the title of Tang Soldier! Tonight, no matter the winner or loser, please drink three cups with me!"

Before Liang Renfang blamed Liu Renwan for questioning his words, so he felt that Liu Renyuan was vulgar and rude, now seeing that the other party really has a heart for the navy, his opinion immediately changed greatly.

Liu Renyuan laughed and said, "Even so, we will never get drunk! Hahaha, when it comes to drinking, who is he afraid of?" But with a squint, he saw the half-smile expression of Fang Jun next to him, as well as Su Dingfang, Liu Rengui, Pei Xingjian and Xi Junmai looked disgusted, coughed dryly, and blushed: "Well, the chief executive doesn't count, he is a Marquis, and he is also the coach. It is unreasonable for us to drink with him, right?"

Several comrades-in-arms all made a gesture that Liu Renyuan had learned from Fang Jun not long ago - raised their middle fingers in unison, expressing contempt for Liu Renyuan's shamelessness.

Liu Renyuan blushed and said angrily, "What are you doing looking at me with such strange eyes? That's right, I'm far inferior to the chief executive in terms of drinking capacity, but what does that matter to you? If you don't accept it, let's fight and kill you all." Put them all down one by one!"

He spoke arrogantly, but secretly regretted that he had said the wrong thing in his heart.

The self-proclaimed drinker was knocked to the ground by Fang Jun not long ago, and he was so dazzled by the drinking that he never dared to brag about his drinking capacity in front of Fang Jun again...

This black boy chief executive can really drink!

Thinking about Fang Jun's drinking capacity, Liu Renyuan's heart trembled...

No one paid any attention to him, they all hurried down the mountain ridge and walked into the dock.

The four sailboats are all of the same model, about 40 meters long, about [-] to [-] meters wide, and the length of the keel is three times the width of the boat.

Several people boarded the deck and looked around.

The sailors on the ship were all craftsmen who built the ship. When they saw Liang Renfang leading a group of officers aboard, they all came out to see him.

At this time, a white-haired old man came out of the cabin, and when he saw Fang Jun, he immediately said "Ouch", bowed slightly, and said with a smile: "Fang Shilang... look at me, I'm an old fool!" , now I have to be called the Chief Manager, the old man sees the Chief Manager, I haven’t seen him for a long time, the Chief Manager’s demeanor is even better than before, he is walking like a tiger, and he is full of energy!"

It turned out to be Zheng Kunchang, the head of the Water Department of the Ministry of Industry...

How did this old man appear here?
Fang Jun hurriedly stepped forward, helped Zheng Kunchang and said, "Why did you come here too? Didn't you hurt me? With your old bones, if one day you confess in Huating Town, your children and grandchildren will come If you ask me to lose money, isn't this Marquis going to go bankrupt..."

Zheng Kunchang laughed loudly and said: "The chief executive is the famous God of Wealth in the Tang Dynasty. How much is this old bone worth? This is the last effort for our children and grandchildren, and I will blackmail you a few dollars to give to our children and grandchildren." Enjoy!"
