Compania care acordă Globurile de Aur, cumpărată de cel mai bogat om din China
După 20 de ani de muncă şi miliarde de dolari cheltuiţi, giganticul telescop spaţial al NASA este finalizat.

De exemplu, dacă 1100 călători ai metroului din Sidney au fiecare câte un telefon, un calcul simplu arată că împreună deţin 62 grame de aur, echivalentul a şase inele de aur.
Calculul se multiplică dacă luăm în considerare un oraş ca Sidney cu 4,3 milioane de telefoane mobile. Asta ânseamnă 2400 inele de aur, sau 243,666 grame de aur. Astfel, în telefoanele mobile din Australia ar fi obţinute din 23 milioane de telefoane mobile nu mai puţin decât 1.320.333 grame de aur.
