Visual guide to the Mandelbrot set


Everyone sure knows fractals, the beautiful mathematical organic drawings. Because they appear similar at all levels of magnification, fractals are often considered to be infinitely complex. Natural objects that are approximated by fractals to a degree include clouds, mountain ranges, lightning bolts, coastlines or snow flakes. The most famous one is the Mandelbrot set, named to the French mathematician.

Programs like Fractint or its successor Xaos make fractal exploring within everyones reach. However, knowing where to zoom in, makes the difference between boring and exciting fractals. Here's a visual guide to fractal exploring, making you feel like Alice in Wonderland.



Michael Paukner is a graphic designer from Vienna and publishes on his Flickr photo stream several nice visualizations ranging from the list of oldest trees on earth to ancient Hebrew cosmology. Very informative and beautifully visualized.

Pizza theorem


I just thought about this :

The volume of a pizza of thickness a and radius z can be decribed by the following formula :
