1982 World Rubik's Cube Championship
The 1982 World Rubik's Cube Championship was a competition for speedsolving the 3×3×3 Rubik's Cube. It was held in Budapest, Hungary, on 5 June 1982. Contestants selected from 19 countries took part. Minh Thai from the United States of America was the winner with a best time of 22.95 after three attempts for each contestant. The top attempt of three was taken as the competitor's score. First prize was a gold-plated Rubik's Cube. Writing shortly afterwards, David Singmaster who was one of the judges, described the competition as being efficiently organized, although at one point power for the TV and the display timer failed in the middle of a trial. The cubes were selected by Ernő Rubik himself, and according to Singmaster "competitors described them as pretty good". However, writing around 20 years later, Jessica Fridrich Jessica Fridrich is a professor at Binghamton University, who specializes in data hiding applications in digital imagery.

Speedcubing
Speedcubing (also known as speedsolving, or cubing) is a competitive sport involving solving a variety of combination puzzles, the most famous being the 3x3x3 puzzle or Rubik's Cube, as quickly as possible. An individual who practices solving twisty puzzles is known as a speedcuber (when solved specifically focusing on speed), or a cuber. For most puzzles, solving involves performing a series of moves or sequences that alters a scrambled puzzle into a solved state, in which every face of the puzzle is a single, solid color. Competitive speedcubing is mainly regulated by the World Cube Association (WCA). The WCA currently recognizes 17 speedcubing events: the cubic puzzles from the 2x2–7x7, the Pyraminx, Megaminx, Skewb, Square-1, and Rubik's Clock, as well as the 3x3, 4x4, and 5x5 Blindfolded, 3x3 One-handed, 3x3 Fewest Moves, and 3x3 Multi-blind. , the 3x3x3 world record single is 3.47 seconds held by Yusheng Du. The 3x3x3 world record average is 4.86 seconds, tied by Max ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Budapest
Budapest (, ; ) is the capital and most populous city of Hungary. It is the ninth-largest city in the European Union by population within city limits and the second-largest city on the Danube river; the city has an estimated population of 1,752,286 over a land area of about . Budapest, which is both a city and county, forms the centre of the Budapest metropolitan area, which has an area of and a population of 3,303,786; it is a primate city, constituting 33% of the population of Hungary. The history of Budapest began when an early Celtic settlement transformed into the Roman town of Aquincum, the capital of Lower Pannonia. The Hungarians arrived in the territory in the late 9th century, but the area was pillaged by the Mongols in 1241–42. Re-established Buda became one of the centres of Renaissance humanist culture by the 15th century. The Battle of Mohács, in 1526, was followed by nearly 150 years of Ottoman rule. After the reconquest of Buda in 1686, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

David Singmaster
David Breyer Singmaster (born 1938) is an emeritus professor of mathematics at London South Bank University, England. A self-described metagrobologist, he has a huge personal collection of mechanical puzzles and books of brain teasers. He is most famous for being an early adopter and enthusiastic promoter of the Rubik's Cube. His ''Notes on Rubik's "Magic Cube"'' which he began compiling in 1979 provided the first mathematical analysis of the Cube as well as providing one of the first published solutions. The book contained his cube notation which allowed the recording of Rubik's Cube moves, and which quickly became the standard. He is both a puzzle historian and a composer of puzzles, and many of his puzzles have been published in newspapers and magazines. In combinatorial number theory, Singmaster's conjecture states that there is an upper bound on the number of times a number other than 1 can appear in Pascal's triangle.
