Royal Society exhibition revives 18th-century debate about shape of the Earth

“Some members of the French Academy of Sciences interpreted measurements taken in Paris by scientists including Jacques Cassini as supporting the idea that the Earth was elongated at the poles, resembling a lemon or a melon.

By contrast, Isaac Newton had proposed that the centrifugal force caused by the Earth’s rotation would result in the planet being flattened at its poles, thus having a similar shape to an orange.”
