Superquark opens the third episode with the great thaw of the Arctic, that immense expanse of ice that in the long winter remains in the dark and freezing, almost as if it were another planet and in the summer, slowly, loses its mantle of ice, the sun is almost always on the horizon, and whales, belugas, foxes, lemmings and large flocks of birds return to swimming, running, flying . Only for the masters of the ice, the polar bears, this is a delicate moment. Especially since the warming has begun to thin the frozen crust and compromise its ancient habitat. In this episode many columns and services, including: with Alberto Angela in the rooms of Augustus and Livia on the Palatine, now enjoyable for the public, after the restoration of the frescoes, which enhance the wonderful original reds and greens . How do you defend yourself from earthquakes? Obviously by trying to predict them and building buildings appropriately, or by reinforcing old ones.
