A statement by the Nobel Committee said Monday that the three scientists’ discoveries “have solved a problem that has occupied philosophers and scientists for centuries—how does the brain create a map of the space surrounding us and how can we navigate our way through a complex environment?”, and that “the positioning system they discovered helps us know where we are, find our way from place to place, and store the information for the next time.”
