Story : An interesting film about the Thar Desert will be shown. Due to the temperatures it reaches and its aridity, it has been nicknamed “the region of death” by the Indians. Here, temperatures often exceed 50 degrees and the amount of rain that falls over the course of the entire year does not reach 5 centimeters. Despite the lack of water and food, there are creatures – including humans – that manage to resist in this extreme environment. Another topic is water in Pompeii. Alberto Angela will follow its flow over the centuries, among the ruins, in the underground, in the aqueduct, in the watersheds, in short in all its paths. Then, we will talk about a small particle accelerator that has come into operation in Pavia to treat tumors in a new and effective way. Barbara Gallavotti, with Francesca Marcelli, went to see how it works and what results it can achieve.
