The Rubik's Cube, a mechanical 3-D puzzle was invented by Hungarian sculptor and professor of architecture Ernő Rubik in 1974.
CUBEHUB
The Cube is an imitation of life itself or even an improvement on life. The problems of puzzles are very near the problems of life, our whole life is solving puzzles. If you are hungry, you have to find something to eat. But everyday problems are very mixed–they’re not clear. The Cube’s problem depends just on you. You can solve it independently. But to find happiness in life, you’re not independent. That’s the only big difference.

Background of Rubik's cube
Originally called the "Magic
Cube",Renamed "Rubik's Cube" by Ideal Toys in 1980
The Rubik’s Cube consists of 26 little cubies.9 cubes are visible on each of 6 sides out of which 12 of them on the sides are counted twice, and 8 of them on vertices are counted thrice.@9*6-12*1-8*[email protected] standard cube has six different colors:white, red, blue, green, orange, and yellow.As of January 2009, about 350 million Rubik’s Cubes have been sold worldwide.
Ernő Rubik,inventor of Rubik's Cube
There are 8 corner pieces that can be arranged in 8! ways, each
of which can be arranged in 3 orientations, giving 38 possibilities for each
permutation of the corner pieces.And also here are 12 edge pieces which can be arranged in 12! ways. Each edge piece has 2 possible orientations, so each permutation of edge pieces has 212 arrangements.In the Rubik’s cube, only 13 of the permutations have the rotations of the corner cubies correct. Only 12 of the permutations have the same edge-flipping orientation as the original cube, and only 12 of these have the correct cubie-rearrangement parity.
The 2x2 Cube(Mini Cube)
2x2 mini cube
This one is the smaller version of the Rubik’s Cube. It's been known as Mini Cube and Pocket Cube also. It is consist of 8 smaller cubes, without having any edge piece. Larry D.Nichols invented a 2×2×2 "Puzzle in 1970 with Pieces Rotatable in Groups" and filed a Canadian patent application for it. The 2x2x2 cube was patented by Ernö Rubik on 29 March 1983, US4378117.
The number of possible positions of the cube is = 3,674,160
The 4x4 Cube(Master Cube/Rubik's revenge)
Rubik's revenge(2nd one)
The Rubik's Revenge is a 4×4×4 version of Rubik's cube, Invented by Péter Sebestény in 1981. The Rubik's Revenge was nearly called the Sebestény Cube until a somewhat last-minute decision changed the puzzle's name to attract fans of the original Rubik's Cube.Unlike the original puzzle (and the 5×5×5 cube), it has no fixed facets: the center facets (four per face) are free to move to different positions.This gives a total number of permutations of 7.40x1045
Solutions
It takes atmost 200 moves to solve this puzzle but speedcubes use around 40-50 moves
There are so many general methods by which we can solve a cube within a couple of minutes.There are so many general methods by which we can solve a cube within a couple of minutes. The most popular method was developed by David Singmaster, published in the book Notes on Rubik's "Magic Cube" in 1981. This solution involves solving the Cube layer by layer, in which one layer, designated the top, is solved first, followed by the middle layer, and then the final and bottom layer. Other general solutions include "corners first" methods or combinations of several other methods.
13 year-old solves Rubik's cube
The quickest way to solve a cube is by Speedcubing that has been developed for solving the Rubik's Cube as quickly as possible. Jessica Fridrich has developed the most common speedcubing solution. It is a very efficient layer-by-layer method that requires a large number of algorithms, especially for orienting and permuting the last layer. The first-layer corners and second layer are done simultaneously, with each corner paired up with a second-layer edge piece.
BLINDFOLDED(OMG!)
Lars Petrus has developed another method in which a 2×2×2 section is solved first, followed by a 2×2×3, and then the incorrect edges are solved using a three-move algorithm, which eliminates the need for a possible 32-move algorithm later. One of the advantages of this method is that it tends to give solutions in fewer moves.This method is also popular for fewest move competitions.

Rubik's cube in movies
First used in ARMAGEDDON,a 1998 science fiction-action film
The Rubik’s Cube, an ultimate brain teaser, is being used in music videos, commercials, and movies. It can be used as a background object to help the audience relate to the character portrayed. Th vast popularity of the puzzle has resulted in several appearances throughout the media and the arts, either as a background object or as a key element. The cube has most likely appeared in too many pieces of media as a background image to count.
Will Smith solving a Rubix cube in The Pursuit of Happyness
Will Smith, an American musician, and an actor is most noted to cubers for his role as Chris Gardner in the film The Pursuit of Happyness, in which he is depicted solving a Rubik's Cube in under two minutes.
The Cube has 43,252,003,274,489,856 different possible configurations.
eek!
The least number of moves required in unscrambling the Cube from the worst disorder, the shortest route, is often called God's Algorithm. Morwen Thistlethwaite calculated it to be 52 moves using computers at the Polytechnic of the South Bank in London.

The first world championship organized by the Guinness Book of World Records was held in Munich on March 13, 1981. All Cubes were moved 40 times and rubbed with petroleum jelly. The official winner, with a record of 38 seconds, was Jury Froeschl, born in Munich. The first international world championship was held in Budapest on June 5, 1982, and was won by Minh Thai, a Vietnamese student from Los Angeles, with a time of 22.95 seconds.
