about Rubik's cube

By 李圳钦 2022-10-25 312次浏览

Rubik's cube, also known as magic cube, was invented in 1974 by Professor Rubik of Budapest Institute of Architecture, Hungary. At the beginning, he invented Rubik's Cube only as a teaching tool to help students enhance their spatial thinking ability. However, it is not only a mechanical problem to make those small squares rotate freely without scattering, which involves wooden shafts, seats and tenons. It was not until the Rubik's Cube was in his hand that he turned it around a few times that he found it interesting and difficult to recover the confused color squares. Rubik was determined to mass produce this kind of toy. Soon after the invention of Rubik's Cube, it became popular all over the world. People found that the gadget made of this small square was really mysterious.
