The Devil's Staircase | Infinite Series
PBS Infinite Series・10 minutes read
The Cantor set, named after Georg Cantor, is a self-similar fractal constructed by removing middle thirds at each stage, revealing points with base 3 expansions without 1's. The Cantor function, also known as the Devil's staircase, is a continuous curve with a length of 2 despite having 0 slope almost everywhere, making both mathematical objects unique with unusual properties.
Insights
- The Cantor set, constructed by removing middle thirds in stages, contains points with base 3 expansions devoid of 1's, revealing a fractal nature that allows infinite zooming despite being uncountable and having a length of 0.
- The Cantor function, or Devil's staircase, characterized by flat and diagonal lines built in stages, showcases a continuous curve with a length of 2, despite having almost zero slope throughout, highlighting its unique and intriguing mathematical properties.
