The Bedtime Scientist

An idea

Finding the way

Maps nobody was taught

Some animals cross an entire ocean or a whole continent and arrive exactly where they meant to go, without a map, a road, or anyone to follow. They carry the directions inside them.

The methods are all different: the Earth's magnetism, the angle of the Sun, a dance, an echo. What they share is a kind of confidence that is hard not to admire.
