Omnipotent Data
Chapter 13 The Raindrop Experiment
"Mom, can I discuss something with you?" Cheng Nuo rubbed Jiang Lan's shoulders attentively and said with a smile.
"What's the matter? Tell me!" Jiang Lan was in a good mood, nodding with a smile.
"Um...can you give me two hundred yuan?" Cheng Nuo rubbed his hands together and said, "Isn't the college entrance examination coming soon? I want to buy some study materials."
"Really? Didn't you buy enough last time?" Jiang Lan asked doubtfully.
Speaking of this, Cheng Nuo felt a toothache.
Although Cheng Nuo's parents limited the promised consumption in terms of pocket money, Cheng Nuo's parents were not stingy at all in terms of learning.
Due to the times, Cheng Nuo's parents were not highly educated. Both are university graduates. So the two put all their expectations on Cheng Nuo.
As long as it was spent on studies, Cheng Nuo's parents didn't discount at all. Even more than that.
Can you imagine Cheng Nuo's mood when he saw the bookshelf full of review materials?
At that time, he even wondered if he was their own!
"Oh, the teacher asked me to buy some materials this time." Cheng Nuo had already practiced the skills of lying without blushing and heartbeat.
Anyway, no matter what, just get the money in your hand.
What Cheng Nuo said was right. The reason why he asked Jiang Lan for money was indeed to buy some materials. However, it is not a study material.
As for Cheng Nuo's review materials, which he slowly piled up on the bookshelf, his own grandchildren might not be able to finish them. He also bought review materials, Cheng Nuo wasn't such a pain in the ass.
For the two hundred yuan, Cheng Nuo had his own plan.
Jiang Lan did not doubt the authenticity of Cheng Nuo's words. Since it was related to study, Jiang Lan took out 200 yuan from her wallet without hesitation and handed it to Cheng Nuo.
"Take it. If the review materials are not enough, I will go to the bookstore another day."
"No, no..." Cheng Nuo waved his hands profusely, "It's enough, these are enough."
"Okay, I'm off to study, you guys keep talking, keep talking."
Cheng Nuo quickly ended the topic and returned to the bedroom with the schoolbag.
"12 floors, 40.54 meters high, 62.48 meters long, 54.24 meters wide, covers an area of 3388.92 cubic meters, 36 households, 10 brightness..."
"Height 175.87 cm, weight 85.24 kg, vital capacity 4002... brightness 2..."
"Speed 54 km/h, weight 3214 kg... brightness 15..."
On the balcony, Cheng Nuo was wearing a casual hooded jacket, lying on the railing and looking at the city in the night sky with his abilities.
Even under the dark night sky, even some things that he couldn't see with his own eyes could be transformed into data and transmitted to Cheng Nuo's brain. It gave Cheng Nuo a feeling that the whole world was under his control.
Cheng Nuo opened his arms to embrace the world.
Suddenly, a gust of cool wind blew, and the cold wind poured in from Cheng Nuo's neckline.
"Ah Choo! It's so cold, so cold!"
Cheng Nuo hastily closed the window and went back into the house shivering with cold.
"The wind speed is 8.7 m/s, and the temperature is 8.2 degrees Celsius." His own eyes gave Cheng Nuo the exact figure.
"Is it going to rain?" Cheng Nuo wrapped himself in a blanket and looked up at the moonless night sky outside.
The air humidity is 92.41%.
Seeing such a value, Cheng Nuo estimated that it was probably going to rain.
Half an hour later, a spring rain fell from the sky as expected.
"Volume 0.05 milliliters, weight 0.051 grams, speed 8.52 m/s..."
"Volume 0.06 milliliters, weight 0.059 grams, speed 9.54 m/s..."
"volume……"
Cheng Nuo lay on the bed and used raindrops to measure how many sets of data he could record at the same time.
Cheng Nuo finally came up with the answer - 100 groups.
At least for now.
Once this number was exceeded, Cheng Nuo's brain felt dizzy. Cheng Nuo was worried that something might go wrong, so he held back the idea of continuing to increase the recorded data against the dizziness.
For the current Cheng Nuo, being able to record 100 sets of data at the same time is enough.
……………
The next day, after a baptism of spring rain, Qingcheng faded away, and the city was filled with the fragrance of soil.
As soon as he arrived at the classroom, Cheng Nuo received Old Tang's call.
"Cheng Nuo, Old Tang is looking for you again." It was Jiang Qingqing who sent the message.
When saying this, Jiang Qingqing gave Cheng Nuo a surprised look. What the hell did Cheng Nuo commit? I was called to a class by Old Tang last night, and I still want to go today?
"Oh, Cheng Nuo, you're here, come here, come here first."
In the office, when Old Tang saw Cheng Nuo walking in, he immediately waved to Cheng Nuo with a smile.
Uh... Cheng Nuo paused.
Old Tang's attitude is really uncomfortable!
"Teacher, are you looking for me?" It was still a familiar opening line.
"Come on, Cheng Nuo, take a look at this question." Old Tang continued to smile.
Cheng Nuo continued to panic...
"See if you can solve this problem?" Cheng Nuo took the problem handed over by Old Tang. I also complained silently in my heart.
Let me do this question directly last night, let me do it twice!
Although complaining in his heart, Cheng Nuo still picked up the question and read it.
"There are n≥2 line segments in the plane, any two of which intersect, and no third line segment intersects at the same point, Geoff picks an endpoint on each line segment and places a frog on this endpoint, Frog Facing the other endpoint, then Geoff will clap n-1 times, each time he claps, each frog immediately jumps to the next intersection of the line segment it is on, and each frog does not change the direction of jumping, Geoff The desire is to be able to place the frogs so that no two frogs land on the same intersection at any time:
(a) Prove that if n is odd, Geoff can always fulfill his wish.
(b) Proof: If n is even, Geoff cannot realize his wish. "
A question that can be called difficult by Old Tang is definitely not a good problem.
Cheng Nuo was calculating in his mind, without any thoughts, pulled a chair, sat on the table in front of Old Tang, and started to untie.
Old Tang also watched Cheng Nuo's movements attentively.
Yesterday, it was because I didn't expect Cheng Nuo to make it, so I didn't pay attention to Cheng Nuo at all.
Now he wants to see if Cheng Nuo has become as genius as he imagined.
Cheng Nuo was writing and drawing on a blank piece of paper. Old Tang was like a student at this time, looking at every number Cheng Nuo wrote on the paper without blinking, and speculated that it was reasonable. sex.
At this time, other teachers in the math group also arrived one by one.
Seeing Old Tang staring at a student solving a problem with concentration, he asked with a smile, "Old Tang, did this student piss you off again?"
The teacher thought that the student should have made a very simple and childish mistake when doing the problem. Old Tang called him to the office and directed him to the steps of the problem.

ps: The unit of brightness I use here is: sb (Xi Ti), and I will use this unit in the future.
