explain three scientist of biology robert hooke ,robert brown lewen hooke
Answers
Answer:
Hooke studied at Wadham College, Oxford during the Protectorate where he became one of a tightly knit group of ardent Royalists led by John Wilkins.
Here he was employed as an assistant to Thomas Willis and to Robert Boyle, for whom he built the vacuum pumps used in Boyle's gas law experiments, and conducted the experiments themselves.
He built some of the earliest Gregorian telescopes and observed the rotations of Mars and Jupiter. In 1665 he inspired the use of microscopes for scientific exploration with his book, Micrographia. Based on his microscopic observations of fossils, Hooke was an early proponent of biological evolution.
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.
He proposed that heat was the manifestation of faster movement of the particles of matter. He performed pioneering work in the field of surveying and map-making and was involved in the work that led to the first modern plan-form map, though his plan for London on a grid system was rejected in favour of rebuilding along the existing routes.
He also came near to an experimental proof that gravity follows an inverse square law, and first hypothesised that such a relation governs the motions of the planets, an idea which was developed by Isaac Newtonand formed part of a dispute between the two which caused Newton to try to erase Lewen hooke
He originated the terraqueous globe theory of geology, disputed the literal Biblical account of the age of the earth, hypothesised the idea of extinction, and wrote numerous times of the likelihood that fossils on hill and mountain tops had been raised there by "earthquakes", a general term of the time for geological processes
In short, Robert Hooke discovered microorganisms.
Robert Brown discovered the nucleus.
Anton van Leeuwenhoek discovered living microorganisms.
