Speedcubing
Many of us have faced various puzzles at least once.
Someone considers it a simple waste of time, and someone has made it his hobby and can not imagine life without them.
But I am sure that both of them have not only heard, but also tried to solve the most famous puzzle of all time — the "Rubik's Cube".
After its invention by the Hungarian architecture teacher Erne Rubik in 1974, a wave of craze for this puzzle swept around the world.
Everyone and everyone, racking their brains, tried to arrange the colors on the faces of the cube.
Enthusiasts began to look for effective assembly algorithms.
Naturally, they were found quite soon, and assembling the cube was not such a difficult task, although there were those who completely refused third party help and wanted to reach the solution themselves.
The classic version of the cube is considered, in which each face is divided into 9 squares, and the cube itself is divided into 27 small cubes (3x3x3).
After the release of the first model, the world saw a lot of its modifications, from 2x2x2 to 7x7x7 and more.
After a crazy surge of interest in the Rubik's Cube, there was a rather sharp and strong decline, which lasted until recently.
Nowadays, interest in the Erne Rubik puzzle has returned and gained new strength.
For many people, building a cube has become a hobby, and for some even something more.
Assembling a Rubik's Cube is not a problem for many now, especially since today, as I have already said, there are many effective ways to assemble a cube.
Therefore, the people went further.
Now it is not the fact of the assembly itself that is important (an interesting story about this is given below), but its speed.
Over time, the high speed assembly of the Rubik's Cube turned into a kind of movement, and even a sport.
And as a result, it acquired its name — speedcubing.
Accordingly, the masters of the high speed assembly of the Rubik's cube are called speedcubers.
Speedcubing began to develop rapidly, the number of speedcubers grew, the build time decreased and decreased.
Today, the high speed assembly of the cube has an international scale and, like in many sports, annual championships are organized for it, both within the country and around the world.
There is also the European Championship.
The assembly time of a 3x3x3 cube is only a few seconds today!
The world record is still held by the Australian speedcuber Felix Zemdegs.
In a single attempt, he was able to assemble the cube in 5.66 seconds (!).
A phenomenal time, especially if we take into account the fact that for a classical cube, the number of possible permissible states is, attention, 43,252,003,274,489,856,000!
After several victories of Felix Zemdegs at the Speedcubing World Championships, the previous champion title holder Eric Akkersdijk said:
I propose to create new categories of world records, one for Felix with his unreal things and one for normal people.
If this does not happen…
I'll leave.
And no wonder, Felix has 44 world records on his account.
Such an object as a Rubik's cube, having such a huge number of initial states, could not be left aside by scientists in any way.
Some people asked the question: "What is the minimum number of turns of the cube needed to assemble it from any initial state?"
Such a number was called the "God Number", and the algorithm by which the cube is assembled, with a minimum number of turns, is called the "God Algorithm".
By the way, as scientists have proved, the Number of God is 20, that is, in any case, there is an algorithm in which a cube can be collected in 20 turns!
Maybe Felix knows this very algorithm?
There are many techniques for assembling a cube.
For beginners, the method of Mikhail Rostovikov is popular, and among speedcubers, the method of Jessica Friedrich has become the most widespread.
If you want to learn how to assemble a Rubik's Cube, then we can recommend you the method described in detail here.
There was a case when a person who solved it himself, without using a ready made method, reached the solution of the puzzle and this became, to put it mildly, a problem.
Graham Parker is the person who collected the Rubik's Cube the longest.
It took about 26 years to assemble it!
By analogy, he can be called a slowcubing champion.
He spent all his free time solving the puzzle, and over time he became so immersed in this activity that for this reason his wife even left him!
So if you canot build a cube, it's better not to get hung up and resort to using a ready made algorithm.
Finally, I would like to say that a Nubik cube is a great thing to usefully kill time.
P.S. By the way, I also started assembling it, but for now, for the sake of sports interest, I'm trying to assemble it myself, like Graham Parker.

At the age of 14, I also set out to simply assemble it, in a couple of weeks I came up with my own way, and I still remember it
Takes 4 minutes
It's far from the record by half a hundred times, but it's mine))))

I once tried to collect it as a child.
The maximum of my success was at the "professional" collection of one facet.
I decided to stop there.

I'm not quite "professional" at the level of collecting only 2 layers so far, but I think I still have everything ahead of me
