Layer By Layer
The Layer by Layer method, also known as the beginners' method, is a method of solving the 3×3×3 Rubik's Cube. Many beginners' methods use this approach, and it also forms the basis of the CFOP speedcubing technique. History The Layer by Layer Method was pioneered by David Singmaster David Breyer Singmaster (14 December 1938 – 13 February 2023) was an American-British mathematician who was emeritus professor of mathematics at London South Bank University, England. He had a huge personal collection of mechanical puzzles and ... in his 1980 book ''Notes on Rubik's "Magic Cube"''. The same idea was adopted by James G. Nourse in his '' The Simple Solution to Rubik's Cube'' which became the bestselling book of 1981, and similar approaches could be found in Don Taylor's ''Mastering Rubik's Cube'' and Cyril Östrop's ''Solving the Cube'' from the same era.

CFOP
The CFOP method (Cross – F2L (first 2 layers) – OLL (orientate last layer) – PLL (permutate last layer)), also known as the Fridrich method, is one of the most commonly used methods in speedsolving a 3×3×3 Rubik's Cube. It is one of the fastest methods with the other most notable ones being Roux and ZZ. This method was first developed in the early 1980s, combining innovations by a number of speedcubers. Jessica Fridrich, a Czech speedcuber and the namesake of the method, is generally credited for popularizing it by publishing it online in 1997. The method works by first solving a cross typically on the bottom, continuing to solve the first two layers together (F2L), orienting the last layer (OLL), and finally permuting the last layer (PLL). There are 119 algorithms in total to learn the full method, with 41 for F2L, 57 for full OLL, and 21 for full PLL. On top of that, there are other algorithm sets like ZBLL and COLL (corners of the last layer) that can be learned in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Singmaster
David Breyer Singmaster (14 December 1938 – 13 February 2023) was an American-British mathematician who was emeritus professor of mathematics at London South Bank University, England. He had a huge personal collection of mechanical puzzles and books of brain teasers. He was 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. Singmaster was both a puzzle historian and a composer of puzzles, and many of his puzzles were 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. Career Davi ...

The Simple Solution To Rubik's Cube
''The Simple Solution to Rubik's Cube'' by James G. Nourse is a book that was published in 1981. The book explains how to solve the Rubik's Cube. The book became the best-selling book of 1981, selling 6,680,000 copies that year. It was the fastest-selling title in the 36-year history of Bantam Books. Writing Nourse wrote the book at the age of 33 while on the staff of the Chemistry Department at Stanford University. Shortly before Christmas 1980 he bought a Rubik's Cube intending to give it away as a present. Instead he spent the holiday season working out a solution (a " Layer by Layer" method), which he published as a 32-page pamphlet for the university bookstore. It reached the hands of a publisher at Bantam who persuaded Nourse to expand the guide into a 64-page book. Publication The book was published June 1981. It became the best-selling book of 1981, selling 6,680,000 copies that year. It was the fastest-selling title in the 36-year history of Bantam Books Bantam Bo ...
