Fractals play an important role in more and more different fields. The new volume Fractals in Science edited by A. Bunde and S. Havlin discusses various aspects of the fractal concept in biology and medicine, chemistry, polymer and geophysics. A special chapter presents 14 programs of fractal models, included on a Macintosh diskette (system requirements: system 6 or 7, b/w monitor, 1 program needs a 256 color display). There is also a MS-DOS edition available.
