Biography of Sir George Biddel Airy (1801-1892)

Geophysical and English astronomer, born in 1801 and died in 1892. Proposed a model isostatic for the explanation of the anomalies present in the gravitational field that is observed in mountainous regions of the Earth's crust.

George Biddel Airy.

Airy, scientific bright this century, achieved the title of Astronomer Royal in 1835, position that he/she held until 1881. Throughout his career, oriented toward the optics and Geophysics school. Improved astronomical measurements, he/she experimented with cylindrical lenses for astigmatism correction, studied the phenomenon of refraction by a beam of light and in the field of geophysics, proposed that mountain ranges is available in the form of huge blocks of variable thicknesses, which were floating on a mantle in State (similar to the icebergs that float on the Ocean) fluid.

With this hypothesis, Airy justified gravitational anomalies that Bouger discovered in the Andes mountains and which were subsequently in the Himalayas. According to this model, gravitational anomalies generated by the topography of mountain ranges regard the level of the sea, be alleviated as a result of the influence generated by the presence of a deep root that was introduced into the mantle.

Airy discoveries were very successful, but he/she also received major failures such as, for example, the rejection of the idea that proposed Faraday on the strength of an electric field lines.
