Emil Wiechert and the Inner Structure of the Earth

Emil Wiechert and the Inner Structure of the Earth

On December 26, 1861, German geophysicist Emil Johann Wiechert was born. Wiechert made many contributions to both fields, including presenting the first verifiable model of a layered structure of the Earth and being among the first to discover the electron. He invented the “inverted pendulum” seismograph, (an improvement still incorporated in today’s instruments), with which he was able to detect some of the Earth‘s inner structure. He suggested the Earth has an inner,…

Carl Størmer and the Aurorae

Carl Størmer and the Aurorae

On September 3, 1874, Norwegian mathematician and geophysicist Carl Størmer was born. Carl Størmer is known both for his work in number theory and for studying the movement of charged particles in the magnetosphere and the formation of aurorae. He also contributed both important photographic observations and mathematical data to the understanding of the polar aurora, of stratospheric and mesospheric clouds, and of the structure of the ionosphere. The discovery of the Van Allen…

Alexis Claude Clairaut and the True Figure of the Earth

Alexis Claude Clairaut and the True Figure of the Earth

On May 13, 1713, French mathematician, astronomer, and geophysicist Alexis Claude Clairaut was born. Clairaut was one of the key figures in the expedition to Lapland that helped to confirm Newton’s theory for the figure of the Earth.[3] In that context, Clairaut worked out a mathematical result now known as “Clairaut’s theorem“. He also tackled the gravitational three-body problem, being the first to obtain a satisfactory result for the apsidal precession of…

Pierre Bouguer – Child Prodigy and ‘Father of Photometry’

On February 16, 1698, French mathematician, geophysicist, geodesist, and astronomerPierre Bouguer was born. In 1735 Bouguer sailed with Charles Marie de La Condamine on a scientific mission to Peru, in order to measure a degree of the meridian arc near the equator. He is also known as “the father of naval architecture” and the “father of photometry“. Pierre Bouguer was educated in mathematics and hydrography by his father Jean Bouguer, who was…
