Robert Hooke

Full Name-

Robert Hooke 

Born-

 28 July 1635

Died-

 3 March 1703

Known for-

1. Hooke's law
2. Microscopy
3. Coining the word 'cell'

Other Information-

1. Built some of the earliest Gregorian telescopes 
2. Observed the rotations of Mars and Jupiter. 
3. In 1665 he inspired the use of microscopes for scientific exploration with his book, Micrographia.
4. He investigated the phenomenon of refraction, deducing the wave theory of light, and was the first to suggest that matter expands when heated and that air is made of small particles separated by relatively large distances.
5. He also came near to an experimental proof that gravity follows an inverse square law, and hypothesized that such a relation governs the motions of the planets, an idea which was independently developed by Isaac Newton.
6. In 1660, Hooke discovered the law of elasticity
7. In 1686, when the first book of Newton's Principia was presented to the Royal Society, Hooke claimed that he had given Newton the "notion" of "the rule of the decrease of Gravity, being reciprocally as the squares of the distances from the Center". At the same time (according to Edmond Halley's contemporary report) Hooke agreed that "the Demonstration of the Curves generated thereby" was wholly Newton's.
8. Hooke made tremendously important contributions to the science of timekeeping, being intimately involved in the advances of his time; the introduction of the pendulum as a better regulator for clocks, the balance spring to improve the timekeeping of watches, and the proposal that a precise timekeeper could be used to find the longitude at sea.
9. Hooke developed the balance spring independently of and at least 5 years before Christiaan Huygens,
10. In 1665 Hooke published Micrographia, a book describing observations made with microscopes and telescopes, as well as some original work in biology.
