The perfect gift for anyone with an interest in the world's scientific history, exposing the scientific theories that were once widely believed but have since been disproven. From such seemingly-crazy ideas as the body being made up of only four things - black and yellow bile, blood and phlegm - to the discovery of dinosaurs' bones being widely accepted as the bones of giants killed in the great flood. When the Earth Was Flat and Animals Magnetic tells the fascinating story behind those scientific theories we once believed to be true, and shows how the way we view the world, and the way the world works, has changed completely throughout history.
