Drawing by Christiaan Huygens of one of his initial stability springs, which can be attached to the equilibrium wheel Hooke built important contributions to the science of timekeeping and was intimately involved in the developments of his time; these incorporated refinement of your pendulum as a far better regulator for clocks, elevated precision of clock mechanisms and using the balance spring to improve the timekeeping of watches.
In 1660, Hooke discovered the regulation of elasticity that bears his name and describes the linear variation of stress with extension in an elastic spring. Hooke 1st explained this discovery in an anagram "ceiiinosssttuv", whose Resolution he revealed in 1678 as Ut tensio, sic vis ("Since the extension, Hence the drive").[103] His work on elasticity culminated in his enhancement with the balance spring or hairspring, which for The 1st time enabled a portable timepiece – a observe – to keep time with sensible accuracy.

Among other items, Hooke outlined "compounding the celestial motions with the planets of a direct motion via the tangent and a lovely movement in the direction of the central body"; his "speculation with the lawes or leads to of springinesse"; a fresh hypothesis from Paris about planetary motions, which he explained at size; attempts to execute or improve national surveys; and the real difference of latitude among London and Cambridge.[a hundred and twenty]

Among the list of observations in Micrographia is of fossil Wooden, the microscopic composition of which Hooke as compared to that of standard Wooden. This led him to conclude that fossilised objects like petrified Wooden and fossil shells like ammonites were being the remains of living things which had been soaked in mineral-laden petrifying water.[143] He thought that these kinds of fossils provided dependable clues concerning the heritage of everyday living in the world and, despite the objections of up to date naturalists like John Ray – who located the thought of extinction theologically unacceptable – that sometimes they might characterize species that experienced turn out to be extinct as a result of some geological disaster.
