This time, the ice emperor remembered that he could control atoms out of thin air. He immediately condensed a handful of coins in his hands and threw them out one by one. I saw all the coins thrown by her standing firmly on the ground.


    Finally, it seems that it''s too troublesome to throw one by one. He threw out all the coins in his hand. It crashed to the ground and all stood up.


    More than that, it seems to prove that he didn''t cheat. She gathered hundreds of coins at one time and held them in her hand. When he threw it into the sky, it all stood up after it fell to the ground.


    Background: "


    Although it is awesome to understand the root cause algorithm at once, this algorithm is useless at first sight. Even if you understand it, what''s the point! It seems that there is no use except to prove that the root algorithm can be obtained by understanding.


    "How''s it going? Is it great? " The ice emperor was elated.


    Although it doesn''t seem to be of great use. But just throw a handful of coins and they can all stand up. They still look very handsome.


    "Well... To some extent, it''s really powerful. If you go to the casino as a dealer? It should be very useful. " It took me a long time to think of a place where this feature might be used. It''s really a wonderful ability to flip a coin 100% to stand up!


    "Well, I know. This algorithm is actually useless. Unless you have to bet with me that coins can be used. " After a burst of novelty, the ice emperor also knew that this ability was not very useful.


    "Well... It''s not completely useless. It depends on what you can regard as coins." Then the photographer took out a cylindrical coin, which looked like a water cup, but painted the pattern of the coin on the two round surfaces: "try if you can treat him as a coin."


    The ice emperor took over the column and thought for a moment. It seemed that he was imagining that the thing in his hand was a coin. Although the shape is a little strange. The height is longer than the diameter, but it is not difficult to associate it with coins.


    A column that could have stood up after being thrown out. But fell down. For a cylinder, the meaning of falling is the same as that of a coin standing up, at least geometrically.


    "Then try this again." The photographer tried several cylinders, then took out a cube, and then painted the pattern of coins on the two opposite sides. It seems that objects without patterns are difficult to be regarded as coins.


    "This thing has completely divorced from the concept of coins!" Even so, the ice emperor tried to imagine the things in his hand as coins and threw them out.


    Pop! The side without pattern falls to the ground, which is similar to that of a coin.


    "Since even objects that are separated from the concept of cylinder are acceptable, let''s try something a little difficult." The shape of the things taken out this time looks quite strange. It looks like a ball as a whole, but one side is pointed. Some faces are circular arcs, although they are angular. But it looks so round that people don''t know what to call this object for a time.


    At one end of the tip of the strange object and the corresponding other side, he drew a pattern, and then handed it to the ice emperor: "try to imagine it as a coin and see if it can stand up."


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


    After the ice emperor threw it out, it sure enough had the same pattern as before, and there was no ground on both sides.


    "I can really go! Actually let this thing land on the side. " The photographer''s expression is quite subtle, as if he saw the end of science.


    "What''s the matter? Is it strange to let him stand? " Ice emperor doubts.


    "Of course it''s strange that this thing can lie on the ground stably. In itself, it is quite unscientific. This thing is called gambutz body on our side. It was made by humans when I came here. First, there is only one unstable equilibrium point and one stable equilibrium point. "


    Ice emperor:


    "What is a stable equilibrium point?"


    Chengying picked up a coin, put it face up on the ground, and put it back up on the ground: "you see, in both cases, the coin can be placed stably, which is the stable balance point."


    Having said that, the undertaker picked up the cube and let the corners of the cube touch the ground, with one finger pressing the other corner: "this is the case. The main center of gravity and the point of contact are perpendicular to gravity. Theoretically, they can stand, but they are very unstable. As long as there is a slight inclination. Will fall directly. This is called unstable equilibrium.


    For a long time, it has been believed that a homogeneous object will have at least four equilibrium points until the gambutz body is proved and manufactured.


    This thing has only two equilibrium points, one is the sharp end. Is an unstable equilibrium. There is also an arc-shaped round head. That''s stable equilibrium. Under normal circumstances, this thing will be like a tumbler.


    But I changed the pattern of coins at both of his equilibrium points. As you can see, after you threw it down, it lay still. Theoretically speaking, it is absolutely impossible for him to maintain balance from this angle. Now the phenomenon of him lying here is the most unscientific embodiment. " As he spoke, he gently touched the gambutz body on the ground, and then saw that it suddenly returned to its normal shape like a tumbler.


    "I think he has no other use except unscientific!" Ice emperor doesn''t care much about this situation. After all, she doesn''t have such a strong scientific world outlook. She has lived in the magic world for tens of thousands of years. This seemingly unscientific situation is used to seeing too much.


    But the nature of the thing in front of her was very different from what she had seen before. What we have seen before may only be the natural rules that have not been discovered or mastered. It looks like magic before you master it.


    But what this thing in front of us violates is not the conventional natural rules, but the laws of mathematics. Although it violates the laws of cognitive geometry, it is not much different from what one plus one is not equal to two in a sense.


    The undertaker sorted out the shattered world outlook and summarized the root algorithm into the category of accommodation, which calmed down.


    "In addition to the current situation, there are other uses for your coin throwing ability. If you throw a coin, it will stand up. So what happens when you throw it in space? "


    The ice emperor was stunned. The coin thrown out will stand up. Yes, but the premise of standing up is that there is at least one plane
