Who invented the Rubik's Cube?

The Rubik's Cube is a mechanical educational toy invented by Hungarian architecture professor and sculptor Ern Rubik in 1974. According to estimates, since its invention, the Rubik's Cube has sold more than 654.38 billion pieces worldwide. Rubik's cube was the most popular in the 1980 s, and it has not declined so far. Soon after its appearance, many similar toys appeared one after another, some of which belonged to the inventor rubik and others. Including 4 × 4 × 4, 2 × 2 × 2 and 5 × 5 × 5 versions of the Rubik's Cube. As the inventor of the Rubik's Cube, Professor rubik holds the Hungarian patent number # 170062, but has not applied for an international patent. He thinks that others don't want to make this kind of toy, but in fact, cloned products appear almost immediately. ) directory hidden 1 what is the Rubik's Cube 1. 1 some basic terms 1.2 the origin of the Rubik's Cube 1.3 the composition of the Rubik's Cube 1.5 the blood of the Rubik's Cube 1.6 the classification of its inventor 2 Rubik's Cube 2.

This is a toy for entertainment. The original Rubik's Cube consists of a third-order cube, 26 small squares and a three-dimensional cross connecting shaft. It contains 6 immovable blocks in the center of the face, 12 blocks in the edge and 8 corner blocks. All six faces have one color. Generally speaking, the colors of a standard Rubik's cube should be blue, white, red, green, yellow and orange, where blue and white are relative, green and yellow are relative, and red and orange are relative. The order of editing some basic terms refers to the number of squares on each side of the Rubik's cube. For example, a third-order Rubik's cube has three small squares on each side. Reduction refers to the process of Rubik's cube from non-original state to original state. Pop refers to the situation that some parts of the Rubik's cube are separated from the Rubik's cube during the restoration process, if it appears as an invalid restoration process in the competition. Dnf, that is, unfinished, refers to the situation that the restorer of the Rubik's Cube feels that he can't finish the Rubik's Cube in a satisfactory time and abstained. There can be dnf in the competition. The origin of editing Rubik's Cube As mentioned at the beginning of this entry, the earliest Rubik's Cube was invented by Professor Rubik's Cube, but it was not for production and entertainment. As a professor of architecture and sculpture, he made the first prototype of the Rubik's Cube to help students understand the composition and structure of the space cube. After he finished his first work, he turned it over a few times and found that the original neat Rubik's cube was difficult to recover, so he realized that this new invention would be difficult. But what he didn't expect was that this toy with a side length of less than 6 cm would be popular all over the world in the future, and even a movement with Rubik's cube as a prop appeared. Editing Rubik's Cube The Rubik's Cube, which was popular in the 1980s, was widely loved by everyone. From 1980 to 1982, nearly 2 million Rubik's cubes were sold. 198 1 year, Patrick Bossert, a little boy in England, wrote a book called You Can Restore the Rubik's Cube (isbn 0 1403 14830), which sold nearly10.5 million copies. Because of the huge business opportunities of Rubik's Cube, Professor Rubik and his partners developed the second-order and fourth-order Rubik's Cube together, and these two products were also successful. In China, the Rubik's Cube was the most sought-after toy in 1980s, and it became the favorite toy of teenagers, just like the handheld game consoles in children's hands today. However, with the reform and opening up, more and more novel toys have entered China, and the Rubik's Cube craze in China is gradually fading. However, in recent years, an informal Rubik's Cube community in China, Rubik's Cube Bar, is trying to change the public's view of Rubik's Cube. Rubik's cube is not only a toy for children, but also a way to relax. Coupled with more exciting and challenging racing and twisting the Rubik's Cube with one hand, more and more people pay attention to the Rubik's Cube again. The composition of the editing Rubik's Cube The third-order Rubik's Cube consists of a central axis connecting six central squares and 20 squares with different structures. When they are connected together, they will form a whole, and either side can rotate horizontally without affecting other building blocks. The fourth-order cube is much more complicated than the third-order cube. Its composition is divided into two categories. One is that the center is a sphere, and each peripheral small block is connected with the slide rail of the center ball, and will slide on the slide rail along the stress direction when moving. The second is the fourth-order Rubik's cube with the axis as the core. The composition of this Rubik's cube is very complicated. Besides the central ball and the peripheral block, there are many accessories. As a racing sport, the fourth-order Rubik's cube with the second structure moves fast and is not easy to get stuck in high-speed rotation. The fifth-order Rubik's Cube has even more components than the fourth-order Rubik's Cube. It takes a long time to invent a new high-order Rubik's cube, because we should not only consider the feasibility of the project, but also consider whether the Rubik's cube can be used stably for rotation after it is made. It is for this reason that the fifth-order Rubik's Cube is the highest-order Rubik's Cube officially announced, and its structure is beyond the imagination of ordinary enthusiasts. At present, there is no official version of the Rubik's Cube above order 6. However, not long ago, it was rumored that some Japanese made samples and sent them to French companies for trial production. The reason why high-order Rubik's cube is difficult to make is that if it is still increased and expanded year by year according to the third-order Rubik's cube, the corner blocks may fall from the air because there is no support when rotating. The so-called eighth-order Rubik's Cube I saw on the Internet before turned out to be just an ordinary third-order puzzle. Editing the bloodline of the Rubik's Cube In fact, the Rubik's Cube does not have only one color scheme. The original version is popular now, but there are actually other versions of color matching. The first one is the original color matching made in Hong Kong, which was sold in the 1980s. The difference between most products sold now and it is that brown has turned into orange. The second type is also made in Hong Kong. It is the same series of Rubik's Cube as the first one, but the color scheme is slightly different. The third one is made in America, and the color scheme has completely changed, from white to yellow, from blue to green, and from red to brown. The fourth one is from Hungary, and its color scheme is close to the Rubik's Cube made in America.
