The great mathematician Benoit Mandelbrot has died at the age of 85 from pancreatic cancer. He is famous for his work on fractal geometry, which has been used in numerous disciplines, from biology to economics. This news has only just been announced, with the first obituary being published online during the time I was planning on writing this piece, see here. Fractal geometry has been used to explain cloud formations, the folding of mammalian brains, the branching of trees, crystal growth and more, it even suggests that the coastline of Britain is infinite! Fractals are also very aesthetically pleasing, mesmerising even, so, in memory of Mandelbrot, here is a video of a fractal zoom.
