Introduction to the Rubik's Cube: In the mathematics exhibition area, there is a large Rubik's Cube. There are text and patterns displayed on each color block of the Rubik's Cube. Visitors can follow the text prompts to put the Rubik's Cube back into its original form. The assembled Rubik's Cube will clearly explain "chaos theory" and "chaos phenomena", helping visitors understand this method that combines qualitative thinking and quantitative analysis.
