Before the invention of modern instruments like GPS or magnetic compasses, various cultures developed highly sophisticated navigation systems by deeply observing their environments. These traditional "wayfinding" methods synthesize astronomy, meteorology, biology, and hydrodynamics to create a mental map of the world.

Polynesian and Pacific Wayfinding Pacific Islanders successfully navigated and settled millions of square miles of open ocean using a mental construct called a "star compass". By memorizing the rising and setting points of over 200 stars, navigators could determine their latitude and precise heading.
