What mandel did?

Mandel, likely referring to mathematician Benoit Mandelbrot, is best known for his work on fractals and the concept of fractal geometry. He introduced the Mandelbrot set, a complex structure that showcases intricate patterns repeating at various scales. This groundbreaking work has had significant implications in fields such as mathematics, art, computer graphics, and nature, revealing the underlying complexity in seemingly simple systems. Mandelbrot's contributions have reshaped our understanding of patterns and dimensions in both theoretical and practical contexts.
