Thermodielectric

Directed by Ana Costa Ribeiro

In this visual essay, Ana Costa Ribeiro uses personal archives to delve into the adventurous, relatively short life of her grandfather Joaquim da Costa Ribeiro, a pioneer in experimental physics in Brazil in the middle of the last century. He was the discoverer of the thermodielectric effect: “something to do with lightning,” as it was explained in a child’s terms to his granddaughter.
