Who wants to put this into proper mathematical notation for me?
union bureaucracy + French as a second language = n(head + brick wall) as n approaches the limit of my ability to can
One of the great mysteries of ancient Peru is that the Inca did not have a system of writing, but communicated with a system of strings tied with knots.
Quipus are made of a cotton or wool strings hanging from a main cord. The knots on the strings convey meaning through their location, direction, and type. Researchers already have a basic understanding of the numerical system incorporated in the quipus, where knots represent numbers. The hope is to move beyond mathematical operations to understanding non-numerical words or phrases from the agricultural product inventories. It is a whole new body of data to add to the Quipu Database Project and to understanding this interesting form of communication.
Series notation continues to amaze me with senseless incomprehensibility.
