Measurement is in the realm of mathematics. It is about keeping track, about establishing dimensions. Some of the earliest measurement activities in human history track back to 35,000 B.C. (Lebombo bone) and 9,000-6,500 B.C. (Ishango bone). Researchers consider them the first measurement tools in human history used for measuring intervals of time.
