Superquark - S16E02: Episode 2

The second episode of Superquark opens with a magnificent documentary from the BBC series The Great Show of Nature: the epic journey of over two million wildebeest, zebras and Thomson's gazelles, across crocodile-infested rivers, to graze on the Serengeti plain made fertile by the rains. But how will they manage to survive in this arena full of carnivores? In this episode many columns and reports, including: the earthquake in L'Aquila has urgently brought up an old question: is it possible to predict earthquakes? Superquark has tried to understand. There is not much gold on Earth. That's why it is precious. But how is gold extracted today? SuperQuark visited one of the largest gold mines in the world: GoldStrike Mountain in Nevada, United States.
