Baidu otaku as Chongzhen

Chapter 21 Spring rain is as expensive as oil ([-])
After a while, Li Zubai's measuring tools from the calendar department of Qintian Supervisor were brought.

a wooden box.

Opening the wooden box, there are things that Yang Reform is "familiar with".

Rulers, set squares, and seemingly compasses.These things are all necessary tools in math class before!In this way, Yang Reform remembered the wooden settable and wooden ruler used by his math teacher in elementary school. If there is chalk and blackboard, hey!Isn't this back to elementary school?

Yang Reform was taken aback.I thought to myself, could the mathematics of the Ming Dynasty be so awesome.There is no big difference from modern tools.

Yang Reform's heart is already filled with huge waves!Didn't the history lesson show that the dynasty was very dark?Why have these things existed hundreds of years ago, have they not improved for hundreds of years?
Originally, I just wanted to use my knowledge beyond time and space from the 21st century to tease and tease these scholar-bureaucrats in the Ming Dynasty, but I didn't expect that such an awesome character would come out of the Ming Dynasty to open my eyes.

Yang Reform couldn't bear it anymore, so he asked, "Li Aiqing, what are you holding in your hand?"

"Reporting to the emperor, what I hold in my hand is named after it. Ruler, triangular ruler, and compass are used to calculate the area of ​​the copper basin and the amount of water. You also need to use scales, buckets, paper and pens. Everything is ready." Li Zubai explained to Yang Reform seriously.

"Hey... this..." This time it was Yang Reform's turn to be dumbfounded.After a while, he said again: "Li Aiqing, please continue."

Li Zubai measured it with the ruler in his hand, then took out the paper, squatted on the ground to write and draw.

Yang Reform looked at it and felt that it was inconvenient for him, so he said to Wang Chengen beside him: "Big companion, it is inconvenient for him to squat here, give him a small stool to use."

Wang Chengen ran down in person and moved a small stool for Li Zubai to facilitate Li Zubai's calculations.Li Zubai was moved so..., and also got the jealousy of the ministers, and the pink eye disease broke out.We all stand, but you have a small stool

After a while, Li Zubai made the calculations: "Your Majesty, I have done the calculations. This copper basin has a round mouth, a diameter of one foot, and an area of ​​about 78 square inches..." Li Zubai quickly made the calculations. [I don’t know if it was called square inch in ancient times]

This made Yang Reform, the otaku who had reviewed the calculation of the area of ​​​​the circle in the middle of the night yesterday, couldn't believe it.

"78 square inches? How did you calculate it? Based on what?" Yang Reform asked.

"My Majesty, I calculated according to the formula of the area of ​​a circle. Multiply the ratio of pi by the square of the radius to get the area of ​​the circle at the mouth of the copper basin."

Yang Reform was taken aback, "formula"!There is a formula in the Ming Dynasty, and I am planning to show it off in the Ming Dynasty, I didn't expect it, I didn't expect it.This formula is obviously the calculation formula of circle area that Yang reformed dreamed back to Baidu yesterday and revisited (circle area = pi x radius squared).

Yang Reform became interested in this, and asked: "Li Aiqing, since you can calculate the area of ​​the mouth of this basin, you can probably calculate how much water there is."

Yang Gaige is also preparing to test Li Zubai's other skills.

Who knew that Li Zubai said, "I report to the emperor that the weight of this water can be obtained by weighing it."

Just weigh it?Yang Reform was speechless.It's as simple as that.I am also going to calculate the volume and weight based on the density of water.

"Then, Li Aiqing, you continue." Yang Reform was speechless. He was about to reveal his own skills. He went back to Baidu in his dream to look up various formulas. He even wrote them down silently. knowledgeable.I can't show off now, and I'm very depressed.

As he spoke, Li Zubai took out a small scale and used a container to weigh the water.

"Your Majesty, the water in this basin weighs about eight taels of money." Li Zubai said. (In the Ming Dynasty, it was 16 taels to a catty. Eight taels is half a catty... half a catty is eight taels, is it a bit dizzy, but it is actually the same weight.)
"Really? In other words, this one-foot-long round basin has been filled with eight taels of water since last night?"

"Your Majesty, yes, it weighs more than half a catty." Li Zubai said seriously.

"Uh...eight taels...why did it become half a catty?" The more Yang Reform said, the lower his voice, and he couldn't understand what was wrong. Is there something wrong with his ears?Or is there something wrong with this person's head?Half a catty weighs the same as eight taels?

Wang Chengen, who was on the side, listened to the emperor talking to himself. He couldn't understand the question of eight taels and half a catty. He was also a little surprised, and quickly reminded in a low voice: "Your Majesty, one catty weighs 16 taels!"

"Cut... scold... 16 taels per catty?? This..." Yang Reform was depressed enough, why is the conversion unit of the Ming Dynasty different from his original one.Feelings When others say "half a catty" means the same weight, I originally thought that "half a catty" meant about the same weight.

"Here, Li Aiqing, if you do the math again, how much rain should fall within this zhang radius?"

"Your Majesty, one foot square is half a catty of water, and one foot square is fifty catties of water." Li Zubai quickly reported the answer.

"Well, that's it! How about a mile? How many catties of water can you get?"

"My Majesty, the length of a mile is 150 zhang, so a radius of one mile is about 100 catties of water." This time Li Zubai calculated it a little longer.After counting this, Li Zubai's forehead was already sweating profusely.Li Zubai already felt that this kind of "super-scale" number calculation was beyond his ability. The number written on the paper was already several lines long, and several sheets of draft paper had been spent.

"Then, what about this hundred miles? I see that the dark clouds are billowing, and they are more than a hundred miles away. You can count it as a hundred miles."

The ministers below have been frightened silly, with a radius of a hundred miles?There are 100 catties of water within a mile, and a radius of a hundred miles... I guess, it's really an astronomical figure.

The minister below was stunned, how could there be so much water above our heads?No way?How come it didn't kill anyone when it fell down?

Are there really so many?

fake?

Really?

confuse!Puzzled!Puzzled!depressed!
The ministers feel that their brains are not enough, how much is this thousand and one million catties of water?How much paper does it take to write this number on paper?
Li Zubai trembled involuntarily.This kind of super calculation exhausted his brainpower.The emperor asked him to calculate the precipitation in a radius of a hundred miles. He estimated that he would have to use a very large piece of paper to complete the calculation and write down the data.

"Report to Your Majesty... Your Majesty... Your Majesty, Your Majesty needs... more paper to calculate." Li Zubai wiped the sweat from his forehead and decided to do the calculation.This kind of technical people, when they encounter challenges in the fields they are familiar with, they will become more courageous as they fight.Is a persistent person.

"can."

After a long time, Li Zubai finally took out an answer tremblingly, but he did not dare to read it, tremblingly raised his head above his head, and said in a trembling voice: "Your Majesty, this... this, this is really... yes... yes ... I... I, minister, minister dare not read."

The ministers in the main hall have eaten a lot of surprises today, and now they are surprised again, what else is there that they dare not read?All very curious.

"Big Companion, go and help Li Aiqing read it."

"Yes, Your Majesty." After Wang Chengen finished answering, he went to help Li Zubai read the answer.

……

Wang Chengen took the paper in his hand, frowned, and after being puzzled for a long time, he read aloud: "110 million..."

Boom~!The hall was like a thunderstorm.The ministers were shocked by this "astronomical" figure!

……

For a long time, no one spoke, and they all digested and accepted today's incident in their hearts.

How can there be so much water in the sky?We throw a brick from the top of the city, and it can kill people. This is called defending the city and killing the enemy.There were tens of billions of catties of water that day, and they fell down. What is this called?How come we were not crushed to death?strangeness!Fake?

The ministers are wondering!

Yang Reform suddenly said: "So much water is in the sky? Why can't I go to the sky? I want to be the emperor, and I also think that one day, I can go to the sky to see!"

Pfft~~~~~!

In the main hall, all the ministers had the urge to spurt their blood to the sky.To ease the impact of this sentence on them.

God!What an innocent topic this is.

serious!Be serious!Don't laugh!

Depressed, uncomfortable, surprised, and again today, some ministers seemed to have been struck by a huge thunder, and their bodies were scorched on the outside and tender on the inside.If you can't say it, you can't do it.
