Rubik's Cube is a device for the improvement of fine motor skills and spatial thinking, a puzzle, a toy, a math problem, special algorithms, world-class competitions and just a beautiful thing in your interior. Any of the above statements will be correct.
What is Rubik's Cube?
Let's talk about this wonderful invention and puzzle. I promise a whole series of useful publications. Want to know more or learn how to solve the Rubik's Cube? Then add the block to your bookmarks!
The 3x3x3 (3D) mechanical puzzle cube appeared in 1974! Originally called the Magic Cube
Thanks to the Hungarian architect Erno Rubik. There is a version that the cube was originally created as a tutorial. With the help of cube, Rubik tried to teach the students the basics of mathematical group theory, as well as to help his students understand three-dimensional objects.
Watch a short video about solving the Rubik's Cube in 1.5 minutes:
On the original classic Rubik's Cube, each of the six faces was covered by nine stickers, each of one of six solid colours: white, red, blue, orange, green, and yellow.
In 1970, Larry D. Nichols invented a 2×2×2 "Puzzle with Pieces Rotatable in Groups". At the same year Frank Fox applied to patent an "amusement device", a type of sliding puzzle on a spherical surface with "at least two 3×3 arrays" intended to be used for the game of noughts and crosses.
In the mid-1970s, Erno Rubik worked at the Department of Interior Design at the Academy of Applied Arts and Crafts in Budapest.[15] Although it is widely reported that the Cube was built as a teaching tool to help his students understand 3D objects, his actual purpose was solving the structural problem of moving the parts independently without the entire mechanism falling apart.
The most difficult thing was to come up with a mechanism that connected 26 cubes that form planes.
It is interesting that the inventor himself collected his creation for the first time for almost a whole month. Originally, the puzzle was called "Magic Cube".
In January-February 1980, the international debut of the cube 3x3x3 took place. In February 1980, the puzzle made its debut at toy fairs in London, Paris, Nuremberg and New York. And the Rubik's cube began its journey around the world.
Types of cubes
There are different variations of Rubik's Cubes. 2x2x2, 3x3x3, 4x4x4 and more. Today physically there are cubes 5x5x5, 6x6x6, 7x7x7, 8x8x8, 9x9x9, 11x11x11, 13x13x13, 17x17x17! There are also virtual cubes with a large number of cubes.
Competitions are held on high-speed assembly of the Rubik's cube. And there are people who can quickly solve it or learn to do it - speedcubers. At the time of this writing, I was able to solve the Rubik's cube in 1 minute, using one of the methods for beginners (I will tell you more in other blog posts). The world record of a speedcube for assembling a 3x3x3 cube is 3.47 seconds as of 2020 (the record was set in 2018).
The following competitions are held in speedy cube assembly, depending on its type:
If you are going to master a Rubik's cube in order to solve it entirely, learn new methods of solving or create patterns on it (like a kind of games), then you just need to understand and use a certain language, a system for transmitting information about actions with a cube.
The cube consists of 26 pieces with 54 colored stickers (surfaces). There are 6 colors in total according to the number of sides of the cube (9 stickers for each color, that is, on one plane). Each side or plane of the cube thus has 9 elements with colored stickers (3 by 3 square). The elements of the Rubik’s cube are of three types. The center cubies (center pieces on each side). This element is the cube with only one colored surface (sticker). This is the base of the cube side. These central pieces have a rigidly fixed spatial position relative to other central elements. And they cannot be moved in any way other than breaking the puzzle. There are 6 parts in total. The edge cubies (pieces). This item has two different colored surfaces (stickers). They are located on the edges of the cube (which is logical and follows from the name). Each Rubik’s cube side has 4 such elements. They make up an equilateral cross. In the middle of this cross is the center of the side. These elements move...
There are several options for making the starting cross. The starting cross making technique is often called " intuitive " and is considered simple. But in reality, for a person who first took a Rubik's cube in hands, there are no "intuitive" and understandable "out of the box" methods. Detailed explanation required. Later, after gaining experience, all the steps of the first stage of the solving really become intuitive and understandable. But at the first acquaintance with the cube, this is not observed, of course. There may be rare exceptions. For acquaintance, I will give three options for making the starting cross: When the cross is immediately solved correctly on the side facing up through the middle layer. When the cross is solved on the opposite side, regardless of the correct location of the edge elements, followed by the correct solving on the main side. When the cross is immediately solved correctly on the starting side facing down. In this b...
