 The Magical Maze: The Natural World and the Mathematical Mind  Prof. Ian Stewart; Mathematics Dept., University of Warwick, UK
At every step in a mathematical investigation you are faced with choices: some choices lead in fruitful directions, most do not. So mathematics is a maze  a logical maze, a mental maze which attempts to parallel the maze of cause and effect that we observe
