The Incas used the decimal system and knots to record 1s, 10s, 100s, 1000s, and so on. The colors of the cords could indicate categories like resources, people, or geographical locations.

Is it possible to understand the Universe without understanding the largest structures that reside in it? In principle, not ...

Each quipu cord may have several knots, which researchers believe the Incan empire used as a decimal system of counting. The knot type, researchers believe, may indicate the magnitude of a number ...

An Inca quipu attached to a wooden frame (1430-1532 B.C.E.). ... The Incas, for example, used a decimal counting system and relied on types of knots, the distance between knots, ...

While the Inca did not develop what we would consider a formal system of writing, they did use recording devices, such as the quipu, a cord with knotted strings suspended from it.

Newly discovered Quipu, a superstructure in which galaxies group together in clusters and clusters of clusters, is the largest known structure in the universe in terms of length, scientists claim.

Named after the Incan system of knotted cords used for recording data, Quipu stretches 1.3 billion light-years across—more than 13,000 times the length of the Milky Way.

The newfound structure is dubbed Quipu after an Incan system of counting and storing numbers using knots on cords.. Like a Quipu cord, the structure is complex, made up of one long filament and ...
