Solving a Rubik's Cube with Blindfold
At first he looks at a Rubik's cube for 11 seconds memorizing the color arrangement of them, then wears a blindfold and solves it in 22 seconds. How could he memorize a disordered color arrangement for a Rubik's cube in such a short period of time?
Yamamoto memorized the important algorithms in solving a Rubik's cube. According to Yamamoto, he converts the positions of cube cells into ‘hiragana’, a type of Japanese writing. Each cell address is assigned to one hiragana letter, then each actual cell position on the disordered cube is also assigned one hiragana letter. In short, every color arrangement is expressed by a combination of "original address" and "current located position". So if a Rubik's cube has 9 cells on one face, he can express the situation on the cube by a string of approximately 20 Hiragana letters.
However, it isn't an easy task memorizing a string of 20 meaningless letters in a moment. However, there is more to this. He makes a breakdown of those letters into pairs of 2 letters, so that he can make Japanese words which consist of two hiragana letters, or words that have 2 syllables. Because hiragana is syllabic letter, every single letter is equivalent to one syllabic sound. For example, you can make a Japanese sentence that consist of 2 words by 4 hiragana letters, such as "Ka-ki (o) ni-ru", or "I cook a persimmon". The sentence will be converted into visual and specific images which makes it easier to memorize.
As a result, there should exist a total of 500 patterns of 2 hiragana letter pairs used for solving a Rubik's cube. He had memorized, by spending a lot of time in advance, learning these patterns. He also had memorized several hundred algorithms for changing the order of one cell, without interfering with the other cells. When solving the puzzle, he only has to evoke his memories and apply them.
