Chapter 18 Chapter 18 in Building Committee

Quan Wuzhi discovered that there are some large wooden pillars in every corner of Sun City, painted with bright black and white stripes, which can be seen from a long distance. Xiaofang'er and his friends walked to one of these striped pillars, and pressed the button on the top of the pillar. "What is this button for?" asked Quan Wu. "It's for calling a taxi." Xiao Fangfang explained. "Anyone who needs a taxi just goes to the pillar and presses the button, and the car will come in a minute." Sure enough, within a minute, a car appeared on the other side of the street.The bodywork is also painted in the same bold black and white stripes as the pillars.The car came close quickly, pulled to the sidewalk, and the doors opened.

"Where is the driver?" Quan Wu asked strangely when he saw that there was no driver beside the steering wheel. "There is no need for a driver." Little Square replied. "It's an automatic push-button car. Instead of the driver, this is, you see, a button with the names of the streets and stations. You press the button you want and the car takes you where you want to go. " Everyone got into the car.Little Square said, "Look, I press this button that says 'Building Avenue' next to it, and..." He pressed a button on the dashboard and the car moved.

"Stop. What are you doing?" Quan Zhi yelled, grabbing the little cube. "What if a car crushes a person?" "The car can't crush anyone, because there is an ultrasonic positioning device inside. It can prevent any accidents of crushing and bumping people." Xiao Fanger said. "Please pay attention to the two large horns in front. A large horn continuously emits an ultrasonic signal forward. As long as there is something in front of it, the ultrasonic signal will start to reflect, that is to say, reflect back from this object and enter the second Horn. The ultrasonic energy here turns into electrical energy. This electrical energy turns on the brake or the turning mechanism. If the obstacle is not big, the car will go around because the turning mechanism is open; if the obstacle is big, the car will stop. Come down, because the brakes are on. There are such horns on the back and side of the car, this is for the ultrasonic signal to be sent in all directions..."

"What exactly does this ultrasonic signal look like?" Quan Mo asked. "Well, how can I tell you? ... This is a very soft sound, so soft that we can't even hear it, but it is still as energetic as the sound we hear." At this time the car drove to the intersection and stopped next to the traffic lights. "There is also an optical device on the car, which will apply the brakes when the light is red." Xiao Fanger said. The car literally stops in front of the traffic lights at the intersection and doesn't go until the light turns green. "What's the matter, it's nothing strange." Xiao Hualian said. "The only thing that's strange is where does the car know where it's supposed to go?"

"Of course the car doesn't know anything." Little Square replied. "Still, he'll take us where we're supposed to go, just by pressing a button. Because there's something called an electronic memory in the machine. It's called a memory because the car seems to memorize the route it's taken. Every car with this device is initially driven by a driver, as if it were a training session. Before this 'coach drive', the driver usually presses a button with the name of the street and drives the car past This street, then press the button with the name of another street, and then drive the car to another street. The steering wheel system of the car is connected with the electronic memory device, so when the button is pressed next time, the electronic The device will automatically drive the car to follow the route you need, and the car can completely do without a driver."

"Well, if that's the case, then there's really nothing surprising." Xiaohualian said. "It would be strange if a car could take us where we want to go without any equipment!" "I would like to ask, what is the structure of this electronic device?" Quan Mo asked. "Is it a tube? Or something else?" "It doesn't use electron tubes, it uses semiconductors." Xiaofang said. "However, I cannot tell you the details, as I am not quite sure myself." "Why use the steering wheel if the car can go anywhere by itself?" asked Clueless.

"This is for when you're on a long trip. Button cars can't go out of town, because out of town travel requires a very complicated memory device. But you can sit at the steering wheel and drive yourself. As long as you hold the steering wheel, the memory The device closes automatically, and the car becomes just like a normal car." Soon, the car turned a corner and stopped in front of a beautiful four-story building.Everything in this house is of various kinds; there are various walls, various balconies, various pillars, various doors, and various windows all kinds.There are round and semicircular; triangular and quadrangular; long and square; rhomboid and oval.Just walk around the house and you'll immediately know what styles windows, doors, balconies, columns and other building components have.There are many small towers and small brick pavilions on the top of the houses, some with spires and some without.They are next to each other, like mushrooms next to an old stump.It looks like there is a Tallinn on the house.If a man builds a new house and intends to put a tower on it for decoration, he only needs to come here and choose the style of tower he likes best.

The wide asphalt square in front of the house is lined with all kinds of cars and motorcycles, and there is a large pile of bicycles next to the entrance. "It seems that everyone is here, we are late for a while. But it doesn't matter." Little Square said. The travelers got out of the car and were led by Cube to the house.They went up a wide staircase, and through a door, into a large and bright hall, full of little people.They sat in chairs as if in a theatre.The Chairman sits at a table in front, with a podium to his right.Behind the podium stood a little man in black, giving a report.On the podium in front of him were rolls of patterns, which he spread out to show the audience.He kept forgetting what to say, and kept looking at his notebook, where he wrote everything down.But his eyes were not working well, so he had to put his glasses on his nose.His glasses were always misplaced and stuffed, and as a result, he had to rummage in his pocket for a long time every time.

"This is the small spinner bottle." Little Fangfang told his companions in a low voice. "He's already started giving his report, but that's all right, we'll all understand if we just pay attention." Xiao Fangfang found three vacant seats in the back row, let Quan Zhi, Xiao Hualian and Xiao Pushpin sit down, and sat himself in a narrow seat in the other row. Don't Know and Little Pushpin began to listen attentively, but they couldn't understand anything, because Little Spinner spoke too profoundly.Xiao Hualian also tried hard to understand a few words. He racked his brains desperately, but after only a minute, he turned his head to the side and fell asleep.The little thumbtack gave him a push and he woke up.But after a minute, his head swung to the other side, and he began to doze again.Little Wuzhi tried his best to open his eyes wide, but he also felt sleepy as hell.

Fortunately, the small rotating bottle ended the report very quickly, and the chairman of the meeting said: "Now let's discuss whether it is possible to build a rotating house." Immediately there came to the table a little man in a blue suit with white stripes and a white-striped tie.He said: "The report of the small spinner bottle is very good. The spinner house, as the experiment proves, can be built, and no one objects to it. However, is it necessary for us to build it? This is the question that should be considered! Finally The bad thing is: the little people who live in the rotating house can't correctly estimate everything around them. I understand what I mean, because I live in the rotating house myself. Listen, how did it turn out? One day , the sun will appear on the window of my room ten to twelve times, and disappear so many times. As soon as the sun appears, I feel that morning has come, but as soon as the sun disappears, I feel that it is night and I should sleep .By noon, I hardly knew whether it was today or yesterday, or perhaps already tomorrow. And in the evening, I felt as if I had lived more than one day, but at least twelve days. I had begun I feel that a day and night are not 24 hours like in the past, but only one hour in total. Therefore, I am always in a hurry, and there is no time to do anything. I feel that the sun is no longer walking slowly in the sky, but Flying as fast as a fly."

Everyone laughed.A little girl in a white dress came up to the table and said: "All this is not so terrible, because you live in a house that turns from right to left, so when you look at the window, you feel that the sun moves from left to right in the sky, that is, from east to west. But I There is a girlfriend who thinks that the sun moves in the opposite direction, because her house does not turn like your house, but turns in the opposite direction. My girlfriend no longer knows which comes first, morning or evening. After which, she can't really tell which is west and which is east. Everything in her head is confused, and lately, she can't even tell her left and right hands." Everyone laughed again.At this moment another architect came to the table.He was a short, thin man with a head like a cucumber, and he spoke as fast as peas, and his words were slurred and his accent was slurred. "It's all nonsense (saying)!" he said, "The sun is not a gun (fly) fly. It cannot fly slowly (full) in the sky. Science has proved that the sun never moves, and the earth is rotating. We all rotate with the earth, so we feel, as if The sun is slow (full) sky nine (walking). If this is just our feeling, then it is nine (walking) fast or nine (walking) slow, from left to oil (right) or from oil (right) to left , Isn’t it the same from period (west) to east or from east to period (west)?” Immediately a new speaker rushed to the table and shouted, "How can this be the same? Gotta get the right impression, not the exact opposite! Nothing to do, huh? We don't know left and right? What if we all walk backwards?" "Well, it's a long way from here!" Someone shouted. The debate intensified.Knowing nothing, I really want to know what decision the architects will make.He didn't even want to sleep anymore.But Xiao Hualian slept like a dead person, and the little thumbtack couldn't wake him up.So she decided to let him sleep peacefully.Everything was fine at first, but then he started sliding off the chair, and the little thumbtack had to hold on to the back of his collar to keep him from falling to the floor.But things got worse and worse, because Xiao Hualian was snoring loudly, and Xiao Wuzhi couldn't wake him up no matter how much he pushed.As a result, Quan Zhi and the little thumbtack grabbed his hands and dragged him out.Xiao Hualian's legs kept rubbing against the ground, and his head was tilted to and fro, much like ears of wheat in a storm. "Look how tired he is!" said Quan Mo. "But it's okay, now we drag him into the street, maybe, he will wake up with some fresh air."
