Web4 de set. de 2024 · Discovery of Cells. The first time the word cell was used to refer to these tiny units of life was in 1665 by a British scientist named Robert Hooke. Hooke was one of the earliest scientists to study living things under a microscope. The microscopes of his day were not very strong, but Hooke was still able to make an important discovery. WebHooke experimented with springs because he thought it must be possible to design a clock or stopwatch which used a circular spring in place of a pendulum for regular time …

Investigate Hooke

WebHooke did propose the inverse square law to Newton, and even the program of ”compounding the celestiall motions of the planetts of a direct motion by the tangent & an attractive motion towards the central body.” These suggestions from Hooke ”occasioned my findings” on planetary motion, Newton admitted. WebWhile it is a commonplace that Hooke formulated this law which today bears his name, it is less well known that Hooke's mature statement on "springy bodies," as presented in 1678 in De potentia restitutiva,2 is fundamentally ambiguous. In particular, Hooke did not clearly differentiate between what notifying worksafe
