S17·E4 Episode 4

In this episode, we will address topics ranging from nature to technology to medicine. The episode opens with the BBC documentary “The Great Rift - water” focusing on the beauty of the fauna and flora of East Africa. Water in all its forms is the absolute protagonist: lakes, waterfalls, rivers, boiling springs, and the ocean that is scanned with latest-generation submarines, and of course the inhabitants of this habitat, from birds to predators. In the report “Telerilevamento”, by Barbara Gallavotti and Gian Marco Mori, the extraordinary three-dimensional images of the Italian territory are shown, obtained thanks to the comparison of satellite and aerial images, elaborated and perfected by computer. An aerial mapping of Italy of great precision, as has never been seen before. For medicine, instead, Marco Visalberghi and Barbara Bernardini, analyze a disease that afflicts 9 million people in Italy: migraine.
