Chapter 307 Make a little money
Compared with the armillary sphere, the armillary sphere is relatively simple.It is a set of several rings together, each representing the meridian, ecliptic, equator, etc., and each ring is marked with various coordinates and scales.

There is one or two peep tubes in the middle for observing the sky.If Li Chengzhi took the trouble to make two concave-convex glass mirrors, or ground them with colorless crystals, this thing would be an astronomical telescope.

To put it simply: the armillary sphere is like a globe with marked latitude and longitude lines, dividing the sky into grids and grids.Which star Hou Xinglang wants to see can be found in the fastest time by gestures with the armillary sphere in the sky.

There is such a building in Beijing's Capital Airport, but what's weird is that the description of that thing talks about the function of muddy phenomena, saying that it can interpret celestial phenomena with dripping and leaking... When Li Chengzhi was in college, he wanted to call more than once. Capital Airport, I suggest that they have a try with a pair of leaky engravings to see if they can turn it up...

Both of these are treasures of China. Even counting from Zhang Heng in the Eastern Han Dynasty, they are hundreds of years earlier than the time when similar instruments were invented in foreign countries.

In an earlier period than this, it should be the Warring States Period. China has observed that a year is 365.25 days, which is the origin of the "Quarter Calendar".It is only 11 minutes longer than the Gregorian calendar implemented by later generations.

And even more amazing. "Zhou Bi Suan Jing", that is, the one that wrote the Pythagorean Theorem, was written probably in the middle of the Warring States period, and it was written:

Around the North Pole, there is an unshakable ice in summer... This refers to the North and South Poles.

Around Zhongheng, there are immortal grasses in winter... This refers to the equator.

Under the North Pole, there is day from the vernal equinox to the autumnal equinox, and night from the autumnal equinox to the vernal equinox...these are polar day and polar night.

This is of course someone else's calculation... When Li Chengzhi saw these few sentences, he wished he could kneel down and kowtow to that book!

so amazing……

Just as I was thinking about it, a bell rang next to my ear.

Li Chengzhi followed the sound and saw that the engraved needle of the big funnel not far away had pointed to noon.

This thing is also very advanced: four large boxes are arranged along the stairs from the height to the bottom, water is used in summer, and fine sand is used in winter.There are mechanisms such as gears and floats inside the box, and there are scales and needles outside the box.Every time the sand or water drops by a quarter (14.4 minutes), the gear will drive the connecting rod to ring the bell outside the box.

The time department of the Taishijian, and the watchmen in the palace and workshops rely on this clock to tell the time and watch the watch. There are such devices in all states, counties and counties...

Geng Chang reminded in a low voice: "Lang Guan, I'm going to court!"

Li Chengzhi looked up, and a group of courtiers poured out from the Tai Chi Hall, looking like a group of ants.

"Then go back!"

……

Back at Taichang Temple, Li Chengzhi was not in a hurry to find Liu Fang and Cui Guang, but to solve the problem of lunch first.

There is a special hall for eating, or one person, or two or three people gather around a table and eat the meals they brought.

Just such a lunch can tell the family background of officials and officials.

Most of them eat millet rice, which was also the mainstream food during the Southern and Northern Dynasties.They are all steamed and then mixed with pickles, such as tempeh, bean paste, pickled cabbage, pickled cucumber, pickled leek, pickled eggplant, etc., pay attention to the meat sauce.What is more distinctive is a kind of rice that is soaked in raw corn, maltose, vinegar and other sauces for ten and a half months, called "飧".

Li Chengzhi was shocked when he first came back from time travel: I feel that there is nothing that the ancients could not marinate.Not to mention wild vegetables, buds, young leaves, etc., but also frogs, mice...

Later, when I learned more, I got used to it: like monks who farmed land for monks, they would starve to death from time to time in good years, but anything that can fill their stomachs is naturally a good thing...

No matter how good the family is, some people eat noodle cakes and rice cakes. This is because flour and rice are more expensive, and the price is roughly two to three times that of polished corn.

All kinds of cakes: marrow cake: made of marrow fat (animal fat), honey (honey) and flour, four to five cents thick, six or seven inches wide... In fact, it is the current shortbread.

Similarly, noodles are mixed with honey, or dead or fermented, or baked, baked, or fried.There are also some bread stuffing inside, or honey or glutinous rice or meat, and flaxseed (sesame) is sprinkled on the cake, which is collectively called white cake.

"Gaohuan" is flour or rice flour rubbing and deep-fried, similar to sazi and twist.The thinner rice noodles are called "charm" cakes, and the wider ones are called "pig skin" cakes, which can be eaten steamed, boiled or fried.

There is steamed glutinous rice with honey, maltose, and various dried fruits, which is no different from today's eight-treasure rice.It needs to be sun-dried and fried again, and it tastes crunchy and crispy, exactly the same as Shaqima.These two unifications are called "white cocoons".

"Chicken and duck" cakes are egg or duck egg cakes. "Shuiyin" is noodles in soup, and "Hoto" is noodles in soup. The noodles are all made with broth, collectively referred to as soup cakes.

There is also an ancient version of rolled meat pancakes or pancakes: long slices of vinegar melon, roasted fat meat, raw mixed vegetables, etc. are quickly rolled in pancakes... This method was passed down from the Western Regions, called Hubing or Hubing meal.

There is also white rice, but it has just become popular in the Northern Dynasties. Because the method is relatively monotonous, officials don't like to eat it.

People from poorer families eat bean rice, but almost no one eats barley rice.It's just because the skin of this thing is too thick, and the beans are hard to swallow if they can't be steamed or pounded.

It's really rare to have four or five dishes like Li Chengzhi, all of which are meat.Even Liu Fang and Cui Guang didn't eat like this.Of course, it was also because the two old men had a small appetite and couldn't eat so much.

When Geng Chang helped him open the food box and take out the food, the officials nearby were stunned.

Is it so stupid?
A box of sausage weighs two catties: chopped mutton, shallots, garlic, leeks, ginger, etc., and poured into the intestines with salt and pepper, or steamed or boiled.

A box of roasted liver: similar to a sausage enema, the liver, lungs, seasonings, etc. are wrapped in morel oil and roasted.Later generations call it fake kidney in Xinjiang, and fat-wrapped liver in Gansu, but it is not delicious when it is cold.

The third is a box of scrambled eggs, and the fourth is a broiled pork belly, that is, fried pork... These four items were not created by Li Chengzhi, but existed in the Yuan and Wei Dynasties.The last box is: crystal elbow.

The elbow is peeled and boned and boiled thoroughly, with the skin facing up and the meat facing down, pressed into the wooden box and pressed tightly, and then poured a layer of thick broth or sauce made from pig skin.

The rice is made into balls, for fear that it will go rancid in hot weather, salt is added to it, and it is wrapped in lotus leaves, which makes people's index fingers twitch.

It was all done by Li Xie when he woke up, and the old man was quite happy: Mr. Lang finally didn't have to stop at restaurants, and he could save a lot of money...

Not to mention the officials, even Taishi Ling Zhao Sheng and Tai Le Ling Gongsun Chong came over with curious expressions.The two looked at the food, and then at Li Chengzhi, as if they were saying: What are the conditions of your family?
Li Chengzhi smiled and handed over two pairs of chopsticks: "You two envoys have a taste?"

These two were not polite, but they didn't pick up the chopsticks, and directly started their hands.Picking up two pieces of elbow and tasting it, Gongsun Chong couldn't help nodding his head: "Well, it melts in the mouth, it's salty, fragrant and tender, not bad!"

Li Chengzhi hit the snake with a stick: "If the two envoys don't mind it, tomorrow I will ask my servant to cook two catties and send it to the house..."

Don't look at it as the "Order" of the seventh rank, but there are still officials.Especially Gongsun Chong, in addition to Shizhong and Shizhong (both are senior advisers to the emperor), he is also Taile Jijiu (Taichang Qing Zuoguan, from the third rank, in charge of ritual and music).When the imperial court formulated the ritual and music system, even Liu Fang and Cui Guang had to help him.

More importantly, this is the teacher of Gao Wenjun and Li Chengxian...

Gongsun Chong chewed the meat and nodded casually.

Li Chengzhi was overjoyed: This is a truly learned man, who can be said to be knowledgeable about the past and the present.All kinds of ancient ritual systems, including degrees, weights, and quantities, are all perfect, otherwise he would not have been used by the emperor to formulate a calendar if he studied rituals and music.

It will definitely be useful in the future, let's fawn on it first...

Somebody muttered "Zhongshu is here", and a group of officials dispersed, leaving only the two commanders and Geng Chang.

Zhao Sheng and Gongsun Chongzheng ate delicious food, and Zhao Sheng pointed to the food box: "Try the Siqing and Jijiu too?"

The two of them went to the court after eating a banquet.Liu Fang shook her head, Cui Guang glanced at the food box, stared at Li Chengzhi and sneered: "Extravagant... Your Majesty is not as good as you!"

Li Chengzhi was a little embarrassed, and secretly slandered: Do you think I don't know, the emperor doesn't eat meat...

Xu had something to say, so Liu Fang called Gongsun Chong and Zhao Sheng away.Jiyu officials were also embarrassed to surround them again. After the case, only Li Chengzhi and Geng Chang were left.

Geng Chang ate corn and rice mixed with pickles. Li Chengzhi invited him to eat with him, but Geng Chang just shook his head.

It is a big taboo to talk lightly and deeply, and Li Chengzhi does not force it.

Geng Chang finally knew why Li Chengzhi brought so much food: how could four or five dishes weigh three or four catties, and seven or eight rice balls would cost two catties, but Li Chengzhi's chopsticks were flying like flying, and he could only eat scum in a moment Not left, better seems to have something to say?

The officials in the vicinity seemed to be frozen, and their eyeballs could not move.

A gust of wind swept through the remaining clouds, Li Chengzhi cleaned up the mess in twos and twos, and wiped his mouth to find Liu Fang and Cui Guang.

"You want to create simple numbers?" Zhao Sheng frowned, "What are simple numbers?"

Gongsun Chong also looked surprised, but the two old men just rolled their eyes and smiled.

Occasionally, they looked at each other, as if to say: Look, the fox's tail is exposed, right?

It was too troublesome to explain, Li Chengzhi looked around, pulled a piece of paper, took out a pencil and said: "Just simplify the calculation, use a charcoal pencil to check the calculation on the wooden board, or even use a stick on the ground. Yes, you can calculate and memorize while saving space..."

"Is it going to be a question?" Cui Guang said with a smile, "I will give you a question: Today there are Tian Guang (width) 650 four steps, and the length (length) is 670 eight steps. What is the question?" Field (area) geometry?"

Li Chengzhi listed a vertical multiplication formula on the paper: 32*43, and he still muttered: "Four eight thirty-two into three. Five eight forty, [-]..."

In just seven or eight breaths, Li Chengzhi gave the answer: 6608 seven and a half acres and half points (740 square feet per mu).

Looking at Zhao Sheng next to him, he hasn't even set up his plan yet?
Zhao Sheng took a breath: "So fast?"

Li Chengzhi nodded, and said again: "This is accumulation. If you are looking for business, it is the same method..." Then he listed the vertical division of the word "factory", which is also seven or eight breaths, and the product will be obtained Checked it again, it's not bad.

Zhao Sheng and Gongsun Chong looked at each other.

To say how difficult Li Chengzhi's algorithm is, it's not necessarily clear: the numbers are still numbers from one to ten, and the algorithm still uses Jiujiuge, but the horizontal algorithm is replaced with a vertical algorithm.

But why has no one thought of it before?

Absolutely convenient: Warlocks and students don't need to bring calculation chips, they can bring a charcoal pencil or not.Finding a stick or stone on the ground would also count...

"You mean it can be simplified, how?" Gongsun Chong asked.

Li Chengzhi rolled his eyes: "It will definitely be faster after simplification... But I haven't figured it out yet, so it will take some time..."

Zhao Sheng was overjoyed: "Can it be faster?"

According to Li Chengzhi, it doesn't matter whether you save money or not, but saving places is second, and saving time is not the key.Instead, there are records when calculating, and warlocks and students no longer have to be afraid of forgetting whether the advance and retreat position is vertical five or horizontal five, and there is no need to go back and recalculate...

It is no exaggeration to say that Li Chengzhi's seemingly inconspicuous change is definitely of epoch-making significance.

Not to mention Zhao Sheng and Gongsun Chong, even Liu Fang and Cui Guang's expressions became solemn.

Liu Fang asked, "How many days do you need?"

How can I?Not to mention the year, how can it be "season"?

Li Chengzhi lowered his head: "At least it will take a few months... But the government office is too noisy and disturbing, so whether you can allow the officials to go home and study quietly, I think it will be possible to study it in three or four months..."

Not to mention March and April, just let him spend two months, and then the ice will be sold to the end...

Liu Fang pondered for a while: It takes ten years to complete a calendar. In comparison, three or four months is already very short...

Just as he was about to agree, he suddenly heard a loud bang.

Cui Guang slapped the case table with a heavy palm, with an angry face, pointing at Li Chengzhi and scolding: "I don't have eyes when I'm an old man? That day was worth a hundred dollars, and that's what you drew in the palm of your hand." Things... clearly have a secret case, but they come here to lie to the old man, and still 'three or four months'?"

Gongsun Chong and Zhao Sheng did not take it seriously: such a big achievement, so what if he is given half a year off?Just treat it as a reward.

Liu Fang thought the same way, thinking that Li Chengzhi already had a secret case, and he worked hard to research it, so he should be let go for a few months.

Just as he was about to persuade him, he suddenly saw Cui Guang winking at him.The two are cousins, they have been together since they were young, and later they are ministers in the same temple.Liu Fang's heart moved, and she immediately understood what Cui Guang wanted to do.

The corner of the old man's mouth twitched, and he said with a smile: "You must have seen that officials from Taichang, doctoral students from Taixue, Guozijian, and Simen Primary School all gathered in Taili, and the number of people is more than a hundred?

If you really have a case, take it out earlier.It can not only share the worries of the country, but also save the bureaucrats from a lot of hard work, and your Majesty will also be rewarded.

But the imperial court has its own rules, don't think about it after a few months of rest, but the old man can allow you to fool around for ten days, but you have to do it sooner, and you have to retreat later..."

Cui Guang snorted again and said, "If I'm an old man, ten days would be too much. But I'm not an unreasonable person. If you want to get away with it, you have to show some real skills... just like the solution of a hundred dollars and a hundred chickens. , if you can submit it, why not let the old man and Bowen allow you to fool around for a month?"

Li Chengzhi was bitter for a while, his face almost turned green.

How can he not see that these two old men are singing oboe?

One ten days is only ten days, what can you do?

The ice was only sold for a fraction...

It has nothing to do with the court's regulations. With Liu Fang and Cui Guang's status, he doesn't have to go to the government for a day, and he can even eat a year's empty salary.

The two old men had obviously guessed that they knew more than that, although they were eager for talent, they were afraid of playing tricks, so they had a red face and a bad face to run on them.

If you say no... that's impossible.

Li Chengzhi wished that all the officials of Wei Dynasty would come to learn mathematics.It's not that liberal arts are not important, but that the two subjects are now seriously out of balance, resulting in almost stagnant production relations and productivity.

Let's see how many scholars are willing to study medicine and how many people are willing to be calendar officials...

These two are dedicated to the public and have no malice, so Li Chengzhi will not complain.He just felt a little powerless, as if he couldn't play with these two old men.

Li Chengzhi felt powerless, and felt that it would be impossible not to magnify his moves.He thought for a while, then gritted his teeth: "If the lower organ can push the Xin rate (pi) to 'sudden'."

The so-called sudden is based on the diameter of a circle of [-] zhang ([-] million) as one zhang, and the units after zhang can be regarded as the digits after the decimal point, which are: chi, inch, minute, centimeter, millisecond, second, suddenly . "Suddenly" is the seventh place...

Gongsun Chong seriously doubted whether Li Chengzhi was talking big, squinted his eyes and asked, "Really?"

There are tens of thousands of predecessors who have calculated Xin rate, but there are very few accurate ones.

In the Shang Dynasty, "3" was counted, and in the Western Han Dynasty, Liu Xin counted to "3.15", so it was named after it.Zhang Heng of the Eastern Han Dynasty calculated "3.16", but it was not very accurate.

It was not until Liu Hui in the Cao Wei Dynasty calculated "3.14159" that it was recognized after more than 100 years of checking and verification, and it was considered to have solved the big problems of astronomers, mathematicians, and even ritual officials and craftsmen in the Northern and Southern Dynasties.

Cui Guangyu and Liu Fang's expressions were serious, Qi Qi asked solemnly: "Really?"

Although Li Chengzhi's temperament is a bit crazier, since he became famous, he has never heard of him breaking his word...

No wonder these two people are excited, mainly because the effect of pi is too great:
According to the cognition of the ancients: the sun, the moon, the five elements, even the Milky Way, and the universe are all in circles around the earth.Counting years, seasons, months, days, hours, four seasons, solstice, 24 qi, and even hours, moments, etc., all of which are inseparable from pi.The more accurate the pi, the more accurate the calendar and time will naturally be deduced.

In addition, the degrees, measures, and quantities used in the national unified system all involve circles.Not to mention all the craftsmen and common people: making wheels, water tanks, furnaces, houses, digging rivers, mining mines... circles involve all aspects of life.Not to mention anything else, if the wheels are rounder, at least the carriage can run faster.

Li Chengzhi muttered to himself: Can this be fake?
This time it was Li Chengzhi who smiled at Mimi: "This Xin rate was not studied by the lower official, but someone else. However, the lower official still has doubts in his heart, so he needs to do some calculations first..."

There is a fart that is suspicious, and it is obvious that they want to talk about conditions. How can the two old foxes not see what Li Chengzhi is planning?
"Stop rambling, submit it now, and I will call someone to check the calculation!"

Liu Fang waved her hand, and said with a loud smile, "If what you said is true, what's the matter with you? I will allow you to enjoy yourself for a month...well, no, March, but you still have to retreat every day..."

This was because Li Chengzhi's mind would get hot and he would run away without a trace.

Li Chengzhi was overjoyed, cupped his hands and bowed down: "Thank you Siqing!"

Cui Guang, however, seemed to have a toothache, his facial features twisted into a ball.

God knows how many good things Li Chengzhi still has in his slippery head. My cousin's mouth is March, so don't we have to wait for March before he can confide a little more?
But Liu Fang has already agreed, Cui Guangzi will not tear down the stage.He took a deep breath and looked at Li Chengzhi suspiciously: "You said it was developed by someone else, but who is it?"

Li Chengzhi was afraid of being misunderstood that this was taught to him by the gods, so he dared to be sloppy.He said honestly: "It's Zu Chongzhi of the Southern Dynasty!"

Liu Fang thought for a while: "Zu Wenyuan who built the Sinan car (guidance car)?"

"Yes, that's the one!" Li Chengzhi replied, "He also created the "Da Ming Calendar", but it was a pity that it was only implemented in the Southern Dynasty for a year before it was abolished..."

Hearing Xiange and knowing elegance, they are all masters. Liu Fang and Cui Guang didn't know that Li Chengzhi was giving them advice.

"Are you sure?" Liu Fang asked suspiciously.

No wonder he was skeptical: there were as many as [-] calendars newly developed in the Northern and Southern Dynasties, but few of them were accurate.This "Daming Calendar" is really as good as Li Chengzhi said, why did the Southern Dynasties abandon it?

"Should be accurate!" Although Li Chengzhi spoke vaguely, he nodded his head heavily, "I heard that Guang Naxin rate, Grandfather has 'cut the circle (the ancient method of calculating pi)' ten thousand times..."

Cut the circle thousands of times?

Liu Fang nodded subconsciously.According to what Li Chengzhi said, if this rate is accurate, there should be little error in deducing the calendar.I will ask the Ministry of Calendar to find out and do some research later...

Cui Guang wondered again: "Even if you are allowed to mess around, you have to retreat every day, and you will definitely not be able to leave Beijing. Then why do you want so many rest (holidays)?"

Li Chengzhi pondered for a while: "The lower official wants to buy a house in the capital, so he plans to make some money in his spare time..."

Capital Homes...Return a small amount of money?

The four present were all wide-eyed.

Sure enough, there is no one worthy of fame: This Li Chengzhi has gone crazy...
