who invented the rubik's cube

From 1962 to 1967, Rubik attended the Budapest University of Technology where he became a member of the Architecture Faculty. [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. Originally called the Magic Cube,[3] the puzzle was licensed by Rubik to be sold by Ideal Toy Corp. in 1980[4] via businessman Tibor Laczi and Seven Towns founder Tom Kremer. Other Rubik's Cube modifications include cubes that have been extended or truncated to form a new shape. To master the cube, you must learn a sequence of movements that can be performed in successive order — the subject of several best-selling books as well as online tutorials.

Thus, there are 12 possible sets of reachable configurations, sometimes called "universes" or "orbits", into which the cube can be placed by dismantling and reassembling it. Laczi an amateur mathematician was impressed.

Fridrich's solution requires learning roughly 120 algorithms but allows the Cube to be solved in only 55 moves on average. In 1986, The New York Times published a deflating article that bordered on an obituary, calling the cube “a bright meteor that burned out.”. Rubik applied for his Hungarian patent in January 1975 and left his invention with a small toy making cooperative in Budapest. The mechanical products include Rubik's Magic, 360, and Twist. The puzzle made its international debut at the toy fairs of London, Paris, Nuremberg, and New York in January and February 1980. A spring between each screw head and its corresponding piece tensions the piece inward, so that collectively, the whole assembly remains compact but can still be easily manipulated. [6], Rubik showed his prototype to his class and his students liked it very much. In 1980, Ideal Toy brought Rubik to New York to a toy fair. In the 1990s, a new generation of enthusiasts discovered it.

With Ernő Rubik's permission, businessman Tibor Laczi took a Cube to Germany's Nuremberg Toy Fair in February 1979 in an attempt to popularise it. Another notation appeared in the 1981 book The Simple Solution to Rubik's Cube. As he was writing “Cubed,” his understanding of his invention evolved, he said. [34] In the US, sales doubled between 2001 and 2003, and The Boston Globe remarked that it was "becoming cool to own a Cube again". In Fewest Moves solving, the contestant is given one hour to find a solution and must write it down. “The cube was growing up next to me and right now, it’s middle-aged, so I know a lot about it.”, Stream: “What the Constitution Means to Me”. (Neither was true). Other similar puzzles have been produced now, based on this concept with several numbers of sides, dimensions, combinations, designs, and stickers. Kremer thought Rubik's Cube was the wonder of the world. [29] In June 1982, the First Rubik's Cube World Championship took place in Budapest and would become the only competition recognized as official until the championship was revived in 2003. [51] Its relative nature allows algorithms to be written in such a way that they can be applied regardless of which side is designated the top or how the colours are organised on a particular cube. The ‘Magic Cube’ is manufactured in small batches and became more and more popular in Hungary during the late 1970s. [16] Rubik applied for a patent in Hungary for his "Magic Cube" (Bűvös kocka in Hungarian) on 30 January 1975,[3] and HU170062 was granted later that year.
