This is how they say it in Hungary «Money. Freedom. Future.»
There are relatively few things we know about Hungary: it's a country of great music festivals, Danube, and the Rubik's Cube. Those who were born in the USSR remember this puzzle as one of the favorite toys from their childhood. Invented in 1975 by Ernő Rubik, a Hungarian sculptor and architect, it caused brains of people of all ages and trades to boil trying to find a solution. In Hungary, the puzzle was better known as "The Magic Cube" (Bűvös kocka in Hungarian). Over 350 mln copies of the puzzle and its various modifications have been sold. It's a lot: if one could place all these cubes in a row, that would be half of the equator.
This bright toy just seems easy – it's almost impossible to solve it quickly for the first time. A standard 3x3x3 cube has 43,252,003,274,489,856,000 different states, which means each attempt is like entering a maze and guessing would be impossible. If one doesn't know the rules or fails to trace every turn of the side, it is easy to get lost!
Mathematicians and programmers spent years trying to find the so-called "Algorithm of God" – a shortest solution to the puzzle. It was possible only in 2010: programmer Tomas Rokicki, engineer John Dethridge and mathematicians Herbert Kociemba and Morley Davidson proved that the puzzle can be solved in 20 moves maximum, regardless of its initial state.
