= Never ending patterns that look the same at any scale. Often exhibit similar patterns at increasingly smaller scales, a property called self-similarity, also known as expanding symmetry or unfolding symmetry Koch snowflake fractal has an infinite parameter but a finite area. Fractal antennas are better than normal antennas. Using the menger sponge --> Infinite surface area but finite volume. Used in cellphone antennas. Chromatin is a fractal that keeps DNA from getting tangled. They exist in river systems, lightning bolts, sea shells and galaxies. ### Mandelbrot Set ![[Pasted image 20230529201034.png]] # Sierpinski Triangle ![[Pasted image 20230529201431.png]] # Menger Sponge ![[Pasted image 20230529201456.png]]
