History Rubik's Cube So, in the 1970s Erno Rubik-Hungarian inventor, worked as a teacher of architecture at the faculty of interior design in Budapest. He believed that the students of the Budapest Academy of applied arts and crafts for the development of spatial thinking need a good understanding of geometry, modeling and mathematics. There are different versions of why Rubik decided to create such an interesting model of cubes, one of them is the one that Erno wanted with the help of this invention to show his students the basics of mathematical group theory. The cube idea was born long time, and the initial task was much harder and almost impossible – Erno wanted to separate the cubes can rotate and not break the entire design. In addition, in his idea the cube had to be 27 cubes with multi-colored faces, that is, only 27 * 6=156 faces(!).

In the final version all of them were 54 – as on modern dice. And inside was placed a cylindrical mechanism. Rubik's students were the first lucky ones to test Rubik's cube. But soon as him, and have "testers" there was a problem: how can it still collect? Say, after creating the cube, Erno spent on Assembly and development of an algorithm about a month!

Competitions In recent years, the speedcuber movement has become so large that with the support of public organizations and various distributors of puzzles (cccstore.ru playlab.ru and camping on D.)???? Championships on spidkubingu, gather hundreds of people from around the world! At such events, participants sometimes show simply phenomenal results (for example, at the CCC Autumn Open 2014 championship Vladislav Shavelsky set the first world record of the Russian-speaking community in the 7x7x7 cube, and Russian Sergey Ryabko twice became the champion of Europe).All participants confirmed that the important thing is to win but to participate. Competition speedcubing is primarily an opportunity to meet old friends and make new acquaintances. The main thing is the atmosphere, which, without exaggeration, can be called unique.

Cube building Compared with the distant eighties, when Rubik's cube has just appeared on the shelves, today the range of models provided on the market has significantly expanded. First of all, this is expressed by the fact that most of its cubes are now made, focused on high-speed Assembly: the faces move very easily, the cube does not jam during Assembly, the tension of the sides is regulated, etcAll this helps speedcubers to reach new heights, set previously unimaginable records in the classical discipline - assembling the cube 3x3x3, 5.25 - a single Assembly, 6.54 - the average of five attempts.
