Fractal image of the Mandelbrot Set

Mandelbrot fractal. Computer graphic showing a three-dimensional fractal image derived from the Mandelbrot Set. Fractals geometry is used to derive complex shapes as often occur in nature. The Mandelbrot Set, named after the mathematician Benoit B. Mandelbrot, is a group of complex numbers. Each point is assigned a colour depending upon its behaviour plotted under a series of simple but repeated mathematical operations or mappings. Generated on a computer screen, fractals are used to create models for real-world non- linear phenomena such as stock market prices, weather forecasting, plant growth, erosion of coastlines and fluid turbulence

TEM of Golgi apparatus in a frog leucocyte

Golgi apparatus. Transmission electron micrograph of a Golgi apparatus in a frog leucocyte (white blood cell). The Golgi apparatus is a system of membranes and vesicles that packages proteins and lipids produced by the cell for export outside. The white circles seen here are vesicles that have budded off from the Golgi apparatus. The dark area at the top is the cell nucleus, bound by the nuclear membrane. The grey disks at the bottom are energy-producing mitochondria. The dark circle close to the Golgi apparatus is a centriole, a cylindrical body (seen here in section) involved in organising chromosomes during cell division. Magnification x85, 000 at 10x8 inch size
