Jornal Nacional: Indigenous people already knew mathematics.

The third episode of the Jornal Nacional special series, featuring Marcelo Viana, director-general of IMPA, explores the relationship between mathematics, nature, and architecture.

For example, why is a sewer drain round? Mathematics provides the answer. Why does architecture use circles, ellipses, and other shapes to construct buildings? Mathematics explains this and shows that, even before the Europeans arrived in Brazil, the indigenous people already knew how to work with matter and apply it to the construction of their huts!
