TED: Fractals and the art of roughness | Benoit Mandelbrot

The video explores the concept of roughness, its historical context, and its measurement. It uses examples like cauliflower to explain fractals and discusses their applications in artificial landscapes and anatomy. The speaker highlights mathematical innovations, the role of fractals in art and nature, and their relevance to stock market analysis. The talk concludes with a discussion on the Mandelbrot set, emphasizing the beauty and complexity of simple mathematical rules.

What is the fundamental aspect of the world according to the speaker?
