“All is number“, this saying already applied in the 5th century B.C. when the brotherhood of the “Pythagoreans“ was founded. Natural, rational and irrational numbers have been an important concept since the creation of the Bible, throughout antiquity up to our modern times. The Fibonacci Numbers, for example, have not only found their use as a numerical pattern in mathematics, they have also been immortalised in art and painting. In this film different and amusing approaches to mathematical methods and processes are illustrated with vivid images, which facilitate pupils’ understanding. In many things that we handle every day fascinating numerical proportions are hidden. Squaring the rectangle and the circle play an important role thereby. Since Greek antiquity the Golden Ratio has been considered to be the epitome of aesthetics and harmony. Together with the extensive accompanying material the DVD is ideally suited for use in the classroom.
