Story : The documentary of the sixth episode of SuperQuark will be a journey inside the brain of anthropoid apes, to discover their surprising qualities. How far can their intelligence go? Their ability to understand? This evening we will discover many hidden aspects of the life of primates, surprisingly similar to ours. Just like us, they often use tools to solve their problems, but even more interesting is to discover that these animals feel emotions, or that they recognize themselves in the mirror. It will be quite an effect to see orangutans sheltering from the rain using a branch full of leaves as an umbrella, or bonobos lighting a fire. A report by Rossella Li Vigni will talk about the use of shock waves in medicine. Then Paco Lanciano and Piero Angela in the studio will show us, with their experiments, experiments how shock waves are formed.
