The n-order magic square is a certain configuration formed by a combination of numbers 1, 2, 3, …, n 2 in an n-order square, which makes the sum of the numbers in each row, column, and two diagonal lines \(n(n^ = 4 3 2 5 2 0 0 3 2 7 4 4 8 9 8 5 6 0 0 0$$ Jiugong map is a zero-dimensional third-order cube. The application prospects of Rubik’s Cube have been discussed according to its rotation characteristics. On the other hand, scholars began to explore the inner movement principles of the Rubik’s Cube structure. All in all, the principles of Rubik’s Cube are contained in numerous scientific systems that involve permutations and combinations, symmetries, and cyclicality. On the one hand, the Rubik’s Cube structure has several features such as rotation, permutation and combinations, and cycle and symmetry, which were treated as physical models or tools to study specific scientific issues or were studied by using scientific theory or methods in some areas. It not only attracts Rubik’s Cube enthusiasts conducting research into Rubik’s Cube reduction algorithms but also draws the attention of scientists and technical workers from various walks of life for its sophisticated design and ideas. It won a German Game of the Year special award and won similar awards for best toy in the UK, France, and the US.Īlthough the Rubik’s Cube reached its height of mainstream popularity in the 1980s, it is still widely known and used. Additionally, it is widely considered to be the world’s best-selling toy. Rubik’s Cube is listed as one of the 100 most influential inventions during the 20th century. This invention caused the widespread interest in the world owing to its unique characteristics, which exerted a profound impact on mankind. Rubik’s Cube is a 3D combination puzzle invented in 1974 by Hungarian sculptor and professor of architecture Ernő Rubik and was originally called the Magic Cube. Finally, the applications and prospects of Rubik’s Cube in the field of mechanism are discussed. After that, the present researches of Rubik’s Cube are reviewed in various disciplines at home and abroad, including the researches of Rubik’s Cube scientific metaphors, reduction algorithms, characteristic applications, and mechanism issues. First, the invention and origin of Rubik’s Cube are presented, and then the special characteristics of the cube itself are analyzed. This paper provides a basic understanding of the Rubik’s Cube and shows its mechanical art from the aspects of origin and development, characteristics, research status and especially its mechanical engineering design, as well as making a vision for the application in mechanism. As a classic brain-training toy well known to the public, Rubik’s Cube was used for scientific research and technology development by many scholars. Remember: If you do not have 2 solved pieces next to each other (like the image above with the 2 white pieces) just perform the following algorithm from any angle and repeat from step 1.Ĥ.Rubik’s Cube is a widely popular mechanical puzzle that has attracted attention around the world because of its unique characteristics. Place your cube blue side down on the table and the green side facing up.ģ. Rotate the whole of your puzzle until the 2 solved corners are at the back of the cube. First look for 2 corners that are correctly permuted in relation to each other (meaning 2 solved pieces next to each other). There are a few different ways to solve this last layer but as this is the beginners method we will stick to just 1 method and then we can progress on to other ways in a later tutorial.ġ. Hopefully at the end of this step you will have solved your 2x2 Rubik's Cube using the beginners method. In step 3 we are going to permute all of the correctly orientated corners of the last layer. Once you have orientated each piece on the final layer you can move on to the final step and permute these pieces. Again, if you are having trouble understanding the stages in step 2, please watch the video ( LEFT) it will guide you through each stage and hopefully you will have nearly solved your 2x2 cube.
