Chapter 5 Solving Equations I
The production team's drying field went out of the village to the south for more than 100 meters.
The whole field is 12 zhang long from east to west, 8 zhang wide from north to south, all of which are laid with large and thick bluestone slabs, and the seams between the plates are hooked with foreign gray, and the whole is very smooth. According to the villagers, before the establishment of the People's Commune, this seed had always been earthy, and if you want to dry some grain in autumn, you have to use cow dung slurry to brush it.
There is a large public house with blue bricks and blue tiles along the north side of the barn field, and in the middle of the house is a large double door, if the door is completely open, even the board cart can be pushed out, probably designed for the convenience of carrying grain. It was still early before the autumn harvest, and the room was empty, even the hamsters had escaped, and a large rusty lock was left hanging on the door.
At about one o'clock, when the sun was at the top, countless white clouds suddenly gathered in the sky, which made the overwhelming heat fade a lot. At this time, Song Xiaoxun and Xie Fangtou were already waiting on the threshing floor, and when they saw me arriving, they hurriedly greeted me loudly, and ran up from the gate of the public house, and diligently caught the spinning top and kite in my hand.
"Hailiu," Xie Fangtou raised the kite in his right hand, held the wire wheel machine in his left hand, shook his head as if he had shaved it with a sickle, and said with a smile: "Xiaoxun and I have been waiting here for ten minutes, and I am worried that you will not be able to come." Song Xiaoxun hurriedly rushed to explain, when he came to the entrance of the village, Xie Fangtou was wandering there, knowing that the two of us were going to come to the grain drying field for activities, so they came with him.
When I heard this, I felt very unfriendly, so I reproached: "It's so hurtful to say 'pestering', Xiaoxun, it's more fun to have one more person." Song Xiaoxun replied, "Yes, yes." Then he told him that he had made a total of three fragrant hemps, all of which had been peeled off, and put them at the gate of the public house in front of him. I glanced at Song Xiaoxun and said dissatisfiedly: "Didn't you tell you to only get two, after a few strokes, you won't play next time?" Song Xiaoxun stretched out his hand in front of me, deliberately checked the weight of the spinning top up and down, indicating that the top was big and heavy, and finally said presciently, "I'm worried that the two hemp together are too thin to move." ”
"Yo ho," I hit Song Xiaoxun on the rib with my elbow, showing an expression of not smiling, and said amusedly: "Count me into obeying you, Xiaoxun, if you want to use two or even three pieces of hemp to fight, do you think you want to hit a cannonball?" Song Xiaoxun laughed twice, and replied stupidly: "Don't use the scales, try your imperial spinning top, let alone weigh a pound, and it is estimated that it is not much different from a cannonball!" ”
"Sea current," Xie Fangtou was a meter away from me and Song Xiaoxun, and asked loudly as he walked upside down, "Do we fly a kite or hit a spinning top first?" ”
I looked up at the sky and replied exactly, "Hit the top first." "And let him take the kite and the wire turbine to the gate of the public house and put it away, and then bring the fragrant hemp over, and Song Xiaoxun and I waited in the center of the field. Xie Fangtou also looked up at the sky as if he was doing it, and said, "Okay." But he turned around and took only two steps, and then turned back and asked, "Do you want to take all the fragrant seac?" ”
I waved the small wooden stick with a spinning top in my hand and said loudly, "Just take one." Also, you place the kite flat on the stone steps in front of the door and press it down with a wheel wheel to prevent it from running around in the wind. After Xie Fangtou asked everything clearly, he said incisively, "Are you not at ease with the kite or me?" He walked quickly towards the gate of the public house.
The original name of solving the square head is to solve the equation, because from every angle, his head is square, so his classmates call him the square head. It is said that his name is still from his grandfather's Xie Tianshu, his grandfather had read a private school for a few days in the old society, and he was familiar with the three-character scripture, but he couldn't write a word, so he hoped that his grandson could have a big career, so he took the name of understanding the equation. And the solution of equations is naturally square, and the intelligence does not seem to be too ideal, and I am still in the second grade at the age of ten, one grade lower than me who is three and a half years younger. In addition to reading, such as talking, doing things, doing farm work, etc., Xie Fangtou does not seem to be weaker than his peers.
When Xie Fangtou went to fetch the fragrant hemp, Song Xiaoxun couldn't put it down and held the spinning top left and right to look at it carefully, so that people could know his heart at a glance, and he also wanted to have the same thing, he looked at it, and suddenly asked curiously: "This imperial spinning top is too delicately sharpened, is it made by your father?" ”
"Heh," I replied casually, half-jokingly, "after watching it for a long time, I finally saw some truth!" Then he asked him rhetorically, do you think you can cut such a process by picking up a kitchen knife? Think that the golden section of the cone and the three exquisite arc lines can be done by hand? Song Xiaoxun looked puzzled and asked, "If you can't do it by hand, how do you do it?" ”
"I didn't expect you to be so good at studying," I deliberately paused for a moment before continuing in a mysterious tone, "I'm afraid you'll be too careful if I don't tell you." It was the gift I received for my sixth birthday, absolutely unique in the world. I also learned afterwards that it was my father who drew the drawings first, then looked around for the best materials, and asked the master of the factory to process them on the lathe. ”
"What are you talking about?" After Xie Fangtou put the kite away, he ran to the center of the field. I took the fragrant hemp that Xie Fangtou had taken, tied it to the neck of the small wooden stick, and replied casually, "Xiao Xun was asking how this spinning top is made just now." ”
"Pig Xiaoxun!" Xie Fang bumped his head against Song Xiaoxun, and said loudly: "Didn't you say last time that the current was made of Brazilian golden sandalwood, and you are asking again, idiot!" Song Xiaoxun also bumped into the other party and shot back: "What a square braincase!" I won't listen to words. Who's talking about the materials to be made, people are asking how the spinning top is made. ”
"Do you still want to ask?" Xie Fangtou tilted his head high, and said vigorously: "This golden sandalwood is hard and heavy, and if the kitchen knife can't be sharpened, use an axe to cut it!" ”
"Alright." I held up the small wooden stick that had been tied to the fragrant hemp and tried to smoke it in the air, and said with a smile: "Fang Tou is actually very smart, if you can't learn it, you can bluff, and if you can't bluff, you can learn it again." ”
Xie Fangtou thought that he had been praised, and said to Song Xiaoxun, "Hmph! ", it means that I still understand people. Song Xiaoxun also ignored it, still holding the spinning top and looking at it, and asked, "Then what is the use of these three arc lines?" ”
"Pig Xiaoxun!" Xie Fang shouted as if he was not in a hurry: "What are you still looking at, tell you, it's decoration, it's cut for good looks, and you don't even understand this?" Don't hurry up and spin the top on the ground first. Song Xiaoxun glanced at Fang Tou, Xie Fang Tou raised his voice and shouted: "What do you see, it's just talking about you!" ”
I couldn't stand it, so I indignantly accused: "Are you two incompatible or are you in the water in your brains, and you are like dogs biting each other for such a trivial matter." Listen to me, this arc is related to the sound and balance of the gyroscope. ”
Song Xiaoxun bowed his body, pressed the emperor's spinning top on a large and smooth bluestone slab with both hands, and spun it hard, and the gyroscope spun up, and he quickly withdrew more than a meter away. I raised my whip and snapped it a few times, and the top began to scurry haughtily across the threshing floor, humming like a helicopter over the field, struggling to flick its huge propellers.
Song Xiaoxun and Xie Fangtou chased and screamed excitedly, as if they were more energetic than the whip smokers. Of course, the imperial spinning top is not in vain, and its ability to resist whipping is definitely worthy of the word "emperor". I had only been pumping for five or six minutes, and I couldn't do any more, so Xie Fangtou came up and pumped violently for six or seven minutes, so that the roar of the emperor's gyroscope after eating the whip continued to echo over the barn; After Song Xiaoxun followed the whip, he was majestic and high-spirited, with a "Who is the hero?" Look at me! "Frame pose, but I used all the strength to feed, and I haven't pumped a few rounds, so I can only say hatefully in front of the spinning top, "You just wait for the next time you eat my whip!" ”
