For John, BLUF: One would think the Math would be settled. Nothing to see here; just move along.
3,700-year-old Babylonian tablet rewrites the history of maths - and shows the Greeks did not develop trigonometry
From The Telegraph, by Science Editor Sarah Knapton, 24 August 2017
The lede plus two:
A 3,700-year-old clay tablet has proven that the Babylonians developed trigonometry 1,500 years before the Greeks and were using a sophisticated method of mathematics which could change how we calculate today.Hat tip to the Drudge Report.
The tablet, known as Plimpton 332, was discovered in the early 1900s in Southern Iraq by the American archaeologist and diplomat Edgar Banks, who was the inspiration for Indiana Jones.
The true meaning of the tablet has eluded experts until now but new research by the University of New South Wales, Australia, has shown it is the world’s oldest and most accurate trigonometric table, which was probably used by ancient architects to construct temples, palaces and canals.
