In the course of the Erasmus + project "Matematics revisited" the students of PTS Gmunden researched about the famous Greek philosopher and mathematician THALES of MILET. 

Posters about his life and his greatest insights were made. 

Among other things, he already calculated the height of the Cheops pyramid on a trip to Egypt about 500 BC.

The pupils of the PTS Gmunden then rebuilt the pyramid in styrofoam on a scale of 1: 200. 

For this purpose, this historical high performance was illustrated by means of posters in order to make them comprehensible to the observers.
