Douluo see you soon

This time, the Ice Emperor also remembered that she could control atoms out of thin air. She immediately condensed a handful of coins in her hand and threw them out one by one. She saw that the coins she threw out were all standing firmly on the ground.

In the end, it seemed that it was too much trouble to throw them one by one. I threw out all the coins in my hand. They fell to the ground with a clatter and all stood up.

More than that, it seemed that she was trying to prove that she was not cheating. She actually gathered hundreds of coins at once and held a handful of them in her hand. She threw them into the sky, and when they landed on the ground with a clank, they all stood upright.

Cheng Ying: "..."

Although it is very powerful to be able to understand the root algorithm at once, this algorithm is useless at first glance. Even if you understand it, what is the point! It seems that apart from proving that the root algorithm can be obtained by understanding, it has no other use

Already.

"How's it going? Is it awesome?" Ice Emperor said proudly.

Although it doesn't seem to be of much use, you can just throw a handful of coins and they will all stand up, which still looks very handsome.

"Well... to a certain extent, it is indeed quite powerful. What if you went to a casino to work as a dealer? It should be very useful." It took Cheng Ying a long time to think of a place where this feature could be used.

The ability to flip a coin and it will stand up 100% of the time is so weird!

"Okay, I know too. This algorithm is actually useless. Unless you have to bet with me to guess coins." After a while of novelty, the Ice Emperor also understood that this ability is actually of little use.

"Well... it's not completely useless, it just depends on what you can regard as a coin." Chengying took out a cylindrical coin, which looked like a water glass, but on two round sides

Draw the pattern of a coin: "Try and see if you can think of it as a coin."

Hyokui took the cylinder and thought for a moment, as if he was imagining that the thing in his hand was a coin. Although the shape was a little weird and the height was longer than the diameter, it was not difficult to think of it as a coin.

After being thrown out, the column that might have stood up fell down. For the column, the meaning of falling is the same as that of the coin standing up, at least in terms of geometric structure.

"Then try this again." Cheng Ying tried several more cylinders, then took out a cube, and then also painted coin patterns on the two opposite sides. Objects that seemed to have no pattern were very simple.

Hard to be treated as a coin.

"This thing has completely broken away from the concept of coins!" Even so, Hyokui still tried to imagine the thing in his hand as a coin, and then threw it out.

Bang! The side without the pattern fell to the ground, again almost like a coin.

"Since we can accept objects that break away from the concept of a cylinder, let's try something a little more difficult." The shape Cheng Ying took out this time looked quite strange. It looked like a ball overall, but there was one side.

It's pointed. Some of its faces are arcs. Although it has edges and corners, it looks very rounded. People don't know what to call this kind of object for a while.

Cheng Ying drew a pattern on the pointed end of this strange object and the corresponding other side, and then handed it to the Ice Emperor: "Try to imagine it as a coin and see if it can stand upright."

Although the object in my hand looks strange this time, based on previous experience, it is not impossible to imagine it as a coin.

After the Ice King was thrown out, it was as patterned as before, with neither side touching the ground.

"I can really go! I actually made this thing land on its side." Cheng Ying's expression was quite subtle, as if he had seen the end of science.

"What's wrong? Is it weird to have him stand up?" Ice Emperor wondered.

"Of course it's very strange. This thing can lie on the ground stably. It's quite unscientific in itself. This thing is called a Gumball body over there. It was made by humans when I came here. It was the first kind and there was only one

An unstable equilibrium point, and an object at a stable equilibrium point.”

ice King:"???"

"What is a stable equilibrium point?"

Cheng Ying picked up a coin, put the coin face up on the ground, and then placed the coin on the ground with the back side up: "Look, in both cases, the coin can be placed stably. This is the stable balance point.

.”

After finishing speaking, Cheng Ying picked up the cube again, placed each corner of the cube on the ground, and pressed one finger on another corner: "In this case, the main center of gravity and the point of contact are perpendicular to gravity. In theory, it can stand, but

It is very unstable. As long as there is the slightest tilt, it will fall directly. This is called an unstable equilibrium point.

For a long time, people have believed that a homogeneous object will have at least four equilibrium points, until the Gumbuz body was proven and created.

This thing has only two balance points, one is the pointed end, which is an unstable balance point, and the other is the arc-shaped round head, which is a stable balance point. Under normal circumstances, this thing will be like a tumbler.

But I replaced the two balance points with coin patterns. As you can see, the thing actually lay down steadily after you threw it. Theoretically speaking, he is absolutely perfect at this angle.

It's impossible to maintain balance. The phenomenon of him lying here now is the most unscientific manifestation." As he spoke, Cheng Ying lightly touched the Gumball body on the ground, and then saw that it suddenly recovered like a tumbler.

into normal form.

"It feels like he has no other use than being unscientific!" Ice Queen didn't care about this situation very much. After all, she didn't have such a strong scientific world view and had lived in a magical world for tens of thousands of years. This kind of seemingly unfair

We have seen so many scientific situations that we have become accustomed to them.

But the nature of the thing in front of her was completely different from what she had seen before. What she had seen before might just be natural rules that had not been discovered or mastered. These things looked like magic before they were mastered.

But what the thing in front of me violates is not the conventional natural rules, but the laws of mathematics. Although it violates the laws of cognitive geometry, in a certain sense, it is not much different from the fact that one plus one does not equal two.

Cheng Ying sorted out the shattered worldview, summarized the root algorithm into the category of contained objects, and then calmed down.

"In addition to the current situation, your ability to throw coins has other uses. If the coin you throw will definitely stand up, what will be the result if you throw it in space?"

The Ice King was stunned. It is true that the thrown coins will stand up, but the prerequisite for them to stand up is that there is at least one flat surface...
