Modulor
A system of proportions used by Le Corbusier. In order to avoid calculating english feet or inches to french metric system, he started using just a few measures on construction site, which corresponded to proportions of a human body (first assumed to be 175 cm tall, later 183 cm).
The system was further elaborated, using the golden section and two Fibonacci Series, one of which is the double of the other. Application of these proportions can be found in many of the buildings of Le Corbusier
There is a picture of the Modulor on the banknote.
