They also beat the Ancient Greeks to it, according to Australian academics
The Ancient Babylonians knew about a form of trigonometry more advanced than the modern-day version – about 1,000 years before its supposed invention by the Ancient Greeks, academics in Australia say.
The astonishing claim is based on a 3,700-year-old clay tablet inscribed with a table of numbers.
Known as Plimpton 322, it is already known to contain evidence that the Babylonians knew Pythagoras’ famous equation for right-angled triangles, long before the Greek philosopher gave his name to it.
In the mid-1990s, 1,000 truckloads of orange peels and orange pulp were purposefully unloaded onto a barren pasture in a Costa Rican national park. Today, that area is covered in lush, vine-laden forest.
A team led by Princeton University researchers surveyed the land 16 years after the orange peels were deposited. They found a 176 percent increase in aboveground biomass — or the wood in the trees — within the 3-hectare area (7 acres) studied. Their results are published in the journal Restoration Ecology.
