"Rubik's Cube And Speedcubing"
History
Rubik's Cube is a 3-D combination puzzle invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik. Originally called the Magic Cube, the puzzle was licensed by Rubik to be sold by Ideal Toy Corp.
• On a classic Rubik's Cube, each of the six faces is covered by nine stickers, each of one of six solid colours: white, red, blue, orange, green, and yellow. In currently sold models, white is opposite yellow, blue is opposite green, and orange is opposite red, and the red, white and blue are arranged in that order in a clockwise arrangement
Mechanics
• A standard Rubik's Cube measures 5.7 centimetres (2 1⁄4 in) on each side. The puzzle consists of twenty-six unique miniature cubes, also called "cubies" or "cubelets". Each of these includes a concealed inward extension that interlocks with the other cubes while permitting them to move to different locations. However, the centre cube of each of the six faces is merely a single square facade; all six are affixed to the core mechanism
Speedcubing
• People who are keen on speedy assembly of the Rubik's cube are called speedcubes. And the speed assembly itself – speedcubing. A solution commonly used by speed cubers was developed by Jessica Fridrich.
Records
• The world record time for solving a 3×3×3 Rubik's Cube is 4.59 seconds, held jointly by Feliks Zemdegs of Australia set on 27th January 2018 at the Hobart Summer 2018
Artificial Intelligence
In November 2015, a machine created by Zachariah Gromko (Zachary Gromko), a student from the United States, collected Rubik's cube for 2.39 seconds.
