Featured Case Study

Oblateness

In the year 1672 John Richer, the astronomer to the Royal Academy of Sciences of Paris, was sent by Louis XIV to the island of Cayenne to make certain astronomical observations. His Parisian clock had its pendulum, slightly over 39 inches long, regulated to beat seconds. Shortly after his arrival at Cayenne, he noticed that the clock was losing time, about two and a half minutes a day. Gravity, evidently, did not act with so much force near the equator as it did at Paris. The astronomer found it necessary to shorten the pendulum nearly a quarter of an inch to get it to swing fast enough.

It is of very great importance in many ways that astronomers and surveyors know as exactly as possible the dimensions of the spheroid. Many men have made estimates based upon astronomical facts, pendulum experiments and careful surveys, as to the equatorial and polar diameters of the earth. Perhaps the most widely used is the one made by A. R. Clarke, for many years at the head of the English Ordnance Survey, known as the Clarke Spheroid of 1866.
