Robert Hooke was and English scientist born in 1635 and died in the year of 1703. Robert Hooke
was born in the town of Freshwater, which is located in the Isle of Write. Hooke was born to a
minister named John Hooke. Robert received a great deal of education that did not take place in
the classroom. He studied with the portraitist Sir Peter Lely (in his youth). He was educated at
the University of Oxford. Then after college he was an assistant of Robert Boyle. He made
curator of experiments to the royal society is 1662, and secretary in 1677-88. Hooke is best
known for his theory of elasticity, in Hooke’s law. In 1665 Hooke became professor of
Geometry at Gresham College, which he occupied till his death. Despite being a famous
scientist, there are no surviving portraits of Hooke.
Hooke’s law of elasticity states that the amount an elastic body bends or stretches out of shape
(strain) is in direct proportion to the force (stress) acting on it. This law applies as long as the
body is still elastic. Increased stress beyond this limit will change the shape of the body
permanently. Robert Hooke had many accomplishments as a scientists the law of elasticity is
what he is most well know for.
Robert Hooke also was the first person to observe the cells of a plant. Using an early microscope
he observed the cells. Hooke took a cork layer of bark from an oak tree and examined it with a
microscope that he made. When observing the cells he noticed the compartments looked like the
small cells of a monastery, so he decided to call them cells. This is a photo, one of hooke’s early
observations. Hooke’s reputation as a biologist is largely do to the book he wrote called
Micrographia, which was published in 1665.
In the book Micrographia he started to use the word “cell” and described the features of plant
tissues that he was able to observe with his microscope. The word cell gradually caught on with
other scientist. Hooke said this about his early observations of the plant cells, “I could
exceedingly plainly perceive it to be all perforated and porous, these pores or cells.” Robert
Hooke had observed the first plant cell, and cell wall.
Hooke’s remarkable engineering abilities enabled him to invent and improve many mechanical
devices. Devices that he improved or invented included timepieces (for which he invented the
spiral spring), the quadrant, he constructed the first Gregorian telescope, and made his own
microscopes. Hooke had many ideas, but failed to follow through on most. He formulated the
theory of planetary motion as a problem in mechanics. He grasped the concept, but did not have
the mathematics to prove it. Sir Isaac Newton completed Hooke’s work by backing it up with the
needed math. Hooke also worked on topics such as the nature of combustion. He created plans of
the first steam engine before they ever existed. Another invention he described was a working
telegraph system as early as 1684. Hooke was like many scientists of the seventeenth century he
worked on many diverse areas of science.
