從數學怪獸到生命密碼：是否存在介於 2 維和 3 維之間的物體？

Why do coastlines grow longer with measurement? How do Koch snowflakes, Cantor dust, and the Sierpinski triangle transform "dimension" into measurable fractions? We also bring our topics into reality—the average 2.714-dimensional airways of the lungs, the self-similar networks of trees and blood vessels, and the algorithmic growth rules in DNA, revealing how nature uses simple rules to create complex wonders. In the final episode, we discuss fractal image compression and computer graphics: when you store a cloud, you might not be storing pixels, but rather the rules themselves.
