Life Without Googol

In a report published this week in the journal Science, researchers describe a group of indigenous peoples in Brazil called the Pirahã tribe. The scientists found that the Pirahã seem to have fewer concepts for numbers than most other cultures. Members of the Pirahã culture have words for one and two — but one, according to the study, can sometimes mean "around one." Larger numbers are "many."
