Who was Emma Castelnuovo?
Emma Castelnuovo (Rome, 1913-2014) was an Italian mathematician and pedagogue.
A graduate of the University of Rome in 1936, she had to take refuge from the Nazis because she was of Jewish descent.
After the war, he rejoined teaching and his contributions are fundamental for the didactics of mathematics.
His desire was to convey the creative spirit of mathematics from observation, manipulation, discovery, logical reasoning and beauty.
Emma Castelnuovo visited Catalonia on several occasions and is a reference for us.
Some modules in this room
The tables where using 4 mirrors we see all the important polyhedras.
A surprising room where geometry makes things change in size.
The three mirrors perpendicular to each other allow the pieces of chain to look correctly forming a chain of 12 links.

Flat images that can only be seen correctly through a cylindrical mirror
Una simple caixa amb miralls que capgira les imatges
Six boxes with interior mirrors that allow you to see a huge variety of mosaics.
It varies the angle of the mirrors and thus creates the different polygons.
A box with four mirrors slightly tilted inside, the front image is repeatedly seen forming a large sphere.
The three mirrors perpendicular to each other allow us to reconstruct a dodecahedron.
