The answer to the calculation power of gyro world

2. Top, the earliest entertainment project in China, is also called "Tuola". It is called "Ganle" in Minnan language, "bingga" or "Da Laoniu" in North China. It is called "spinning
top" in English and "lue" in Japanese, which is called "KOMA"
children's toys, which are shaped like a conch, are mostly made of wood and have iron tips underneath. When playing, they are wrapped with ropes and pulled out to make them stand upright and rotate. Some are made of iron sheet and use the spring force of the spring to rotate
the traditional top is roughly an inverted cone made of wood or iron, and various materials and shapes have appeared in modern times< The top is a familiar toy for teenagers. Now, this kind of toy is popular all over the world. China is the hometown of top. From the Neolithic sites in Xiaxian County, Shanxi Province, stone gyroscopes have been excavated. It can be seen that gyroscopes have a history of at least four to five thousand years in China
in the Jin Dynasty more than 1700 years ago, another interesting toy, bamboo dragonfly, appeared in China. After this toy was introced to Europe in the 18th century, it was called "Chinese top" by the West. It can be seen that the real top spread abroad earlier than this
why is the bamboo dragonfly called "China top"? The term "gyroscope" was formally proposed by Francois BOCO, a French physicist in the mid-19th century. In English, top means "revolving body". The top is a revolving body rotating on the ground, and the bamboo dragonfly is a revolving body rotating in the air, so the bamboo dragonfly is also a kind of top< In this way, all revolving bodies can be regarded as gyroscopes. For example, the Diabolo we play, the disc spinning, plate playing, hat throwing in acrobatics, and the fast spinning ballet all use the gyroscopic principle. Gyroscopes can be seen everywhere in the world around us. As small as atoms and as large as the earth, they are gyrating "gyroscopes".

3. If he's in the real world, there's no doubt 1. According to the plot, the edge of consciousness is nihility, which needs to be created by yourself, which explains the Japanese residence and projection, However, the Japanese died after Kaobo and others entered the edge of consciousness (Kaobo, Ariadne and Fisher's fourth layer of dream is the edge of consciousness world, otherwise why Fisher was killed and didn't return to the second layer of dream, but in the next layer). In the same time, Kaobo's aging degree should be better than the Japanese, but in the plot, the opposite is true, As soon as Kaobo arrived at the airport, his father-in-law appeared. According to common sense, Kaobo did not know whether he would be able to go into the United States without being arrested. In theory, he should not have told his father-in-law about this kind of thing in advance. The main problem of doubt 3 is that there are too few things about the edge of consciousness mentioned in the plot, According to Cowper and his wife's joint exploration of the edge of consciousness, it seems that if the edge of consciousness is shared, the dreamer and the subject can not be distinguished, because they can create buildings in their dreams, and the plot knows that if they have not entered the edge of consciousness, the edge of consciousness is nothingness. When Ariadne and filch enter, their edge of consciousness space is nothingness, so they only show Cowper, So why does koubo only show the marginal world of Japanese consciousness after meeting with Japanese? If it coincides, how does it coincide, and how does Kao Bo enter the world
if Cobb is in a dream, what is he in? If he is on the edge of consciousness, he must destroy the original building before rebuilding it. It will take years for him to forget it. Therefore, when he meets the Japanese, he should be able to distinguish reality from dream, In the edge of consciousness, people are aging according to the law of nature. When he meets the Japanese, he is still a little old, but when he is on the plane, he becomes young again, so it should not be the edge of consciousness. But if it was a normal dream, how could he meet the Japanese? It is impossible to commit suicide by returning to reality
some people don't say that details like rings can decide. If he is in a dream, everything may change with his subconscious mind except the rotation of the top, which is not enough to be the basis. Only logic can finally explain everything
to sum up, there is no real ending. You think reality is reality, and dream is dream, because there are loopholes in any logic, so just be happy as you like.
