Robert Hooke: Experiments
built 641 days ago
Hooke's activities in astronomy extended beyond the study of stellar distance. His Micrographia contains illustrations of the Pleiades star cluster as well as of lunar craters. He performed experiments to study how such craters might have formed.[6] Hooke ... was an early observer of the rings of Saturn,[7] and discovered one of the first double-star systems, Gamma Arietis, in 1664.[8]

Bonhams is delighted to announce the forthcoming sale of Robert Hooke's autograph minutes of the Royal Society, recording experiments conducted by him as Curator from 1661 and his correspondence as Secretary from 1677. This three-inch thick manuscript volume will go on display from Tuesday 14 March at Bonhams' New Bond Street salerooms, prior to its sale there on Tuesday 28 March. It is expected to make in excess of £1 million.

H[O]oke was an English experimental physicist, but his versatility led him into several fields. He was the first to state clearly that the motion of heavenly bodies must be regarded as a mathematical problem and he approached in a remarkable manner the discovery of universal gravitation.

Hooke joined the Royal Society as the first Curator of Experiments in 1662 and later went on to become the Society's Secretary. He performed experiments to the public and was the first paid scientist.

Hooke did some of the earliest experiments in skin grafting, blood transfusion and artificial respiration. He correctly predicted that lungs take something from the air in the act of breathing. He was awarded a doctorate for his services to medicine.

In 1660, he discovered Hooke's law of elasticity, which describes the linear variation of tension with extension in an elastic spring. In 1662, Hooke gained appointment as Curator of Experiments to the newly founded Royal Society, and took responsibility for experiments performed at its meetings. His work on elasticity culminated, for practical purposes, in his development of the balance spring or hairspring, which for the first time enabled a portable timepiece - a watch - to keep time with reasonable accuracy. A bitter dispute between Hooke and Christiaan Huygens on the priority of this invention was to continue for centuries after the death of both; but a note dated 12 June 1670 in the Hooke Folio (see
