The Klein Project (http://blog.kleinproject.org/) aims at establishing a learning community based on contacts between schools and the contemporary mathematical research.
The so-called “Klein vignettes” are an instrument that witness this connection between school and research; each of them is a short essay outlining a specific mathematical theme
If you have suggestions for the “vignettes”:
– In Italian, please contact Prof. Ferdinand Arzarello ()
– In other languages, please go to the following link http://blog.kleinproject.org/?page_id=2 where you will find the detailed rules.
