Schiehallion's isolated position and symmetrical shape were well-suited to the experiment. The experiment had previously been considered, but rejected, by Isaac Newton as a practical demonstration of his theory of gravitation ; however, a team of scientists, notably Nevil Maskelyne , the Astronomer Royal , was convinced that the effect would be ...
Schiehallion has a rich flora, interesting folklore and archaeology, and a unique place in scientific history for an 18th-century experiment in "weighing the Earth". It is near the centre of mainland Scotland .
The Hollow Earth is an obsolete concept proposing that the planet Earth is entirely hollow or contains a substantial interior space. Notably suggested by Edmond Halley in the late 17th century, the notion was disproven, first tentatively by Pierre Bouguer in 1740, then definitively by Charles Hutton in his Schiehallion experiment around 1774.
Reuben Burrow (30 December 1747 – 7 June 1792) was an English mathematician, surveyor and orientalist. Initially a teacher, he was appointed assistant to Sir Nevil Maskelyne, the fifth Astronomer Royal, at the Royal Greenwich Observatory, and was involved in the Schiehallion experiment.
Nevil Maskelyne FRS FRSE (/ ˈ m æ s k ə l ɪ n /; [1] 6 October 1732 – 9 February 1811) was the fifth British Astronomer Royal. [a] He held the office from 1765 to 1811.He was the first person to scientifically measure the mass of the planet Earth. [2]
He was elected a Fellow of the Royal Society in July, 1774 [5] He was asked by the society to perform the calculations necessary to work out the mass and density of the earth from the results of the Schiehallion experiment – a set of observations of the gravitational pull of a mountain in Perthshire made by the Astronomer Royal, Nevil ...
1774 – Charles Mason: Conducts an experiment near the Scottish mountain of Schiehallion that attempts to measure the mean density of the Earth for the first time. Known as the Schiehallion experiment. 1796 – Edward Jenner: tests the first vaccine. 1798 – Henry Cavendish: Torsion bar experiment to measure Newton's gravitational constant.
