La symétrie

S1 E16
·
2014

The human brain likes symmetrical things! Some living things and structures are symmetrical, such as the monarch butterfly and the Taj Mahal. Our host Jean-François explains what the axis of symmetry and the reflection are. To find other everyday objects that are symmetrical, our two investigators go in search of them. Participants are challenged to reproduce an image while a partner draws its reflection. We explore the Mona Lisa, the well-known work of art by Leonardo da Vinci.
