Australian mathematician discovers the geometry applied on the 3700-year-old plaque: For selling a piece of land

An Australian mathematician has discovered what may be the oldest example of applied geometry on a 3700 - year - old Babylonian clay tablet. Known as Si.427, the plaque carries the plan of a field that measures the boundaries of a piece of land. The tablet dates from the old Babylonian period between 1900 and 1600 BC [...]
Known as Si.427, the plaque carries the plan of a field that measures the boundaries of a piece of land.
The tablet dates from the Old Babylonian period between 1900 and 1600 before the Orient of Krust and was discovered at the end of the 19th century in what we now know as Iraq.
She was sheltered at the Istanbul Archaeological Museum before Daniel Mansfield of the University of New South Wales tracked her down, reports Guardian.
Mansfield and Norman Wildberger had earlier identified another clay tablet containing the oldest accurate trigonometric chart.
You usually do something practical,” Mansfield at that time.
