"The Inca system of Quipu — tying a series of Cotton knots to record information—is providing a surprising model to modern physics and quantum computing.
~Complex information can be stored in many ways. Three methods—written human language, the binary code of computers and the DNA and RNA sequences of genetics—dominate today's technologies.
~But there is a beautiful, ancient method of storing and processing information that incorporates elements of all three and adds something unique: topology, the science of stable shapes and structures."
c. 2600 BC – 17th century (some variants are used today)
