How big is big? Did you know that a blue whale's tongue weights the same as a single African elephant and that an entire whale weights the equivalent of 25 elephants? Or that a volcano can unleash the energy of 100 hydrogen bombs. Or that that 76 trombones make the same noise as a thunderclap? Journalists have long recognized that it's possible to grasp the magnitude of big things by describing them through visual equivalents or analogies, which is why they describe rainforest, for instance, as being destroyed in areas the size of Wyoming or Wales. In this fascinating and fun reference, you will discover how many times higher than Monsieur Eiffel is the Eiffel Tower, and how many Eiffel Towers there are in a Mount Everest, how many grandfathers take you back to the Jurassic period, and much much more!
