Robert Hooke

Robert Hook, (born July 28, 1735, New style), 1635, Freshwater, Isle of Wight, UK - March 3, 1703, London), British physicist, he found a law of elasticity called For Hooke's law, and who has studied in various fields

In 1655, Hook was hired by Robert Boyle and produced Boyle's air pump. Five years later, Hook discovered his elastic law. It states that the elongation of solids (metal, wood, etc.) is proportional to the force applied to it. The law studied stress and strain and laid the foundation for understanding elastic materials. He applied these studies to the design of a balance spring of a wristwatch. In 1662 he was appointed as a laboratory curator of the Royal Society in London and was elected as a researcher the following year.

As one of the first to build a Gregory reflection telescope, Hook found the star of the fifth constellation of the trapezoid, Orion, in 1664, and it suggested that Jupiter will rotate around its axis for the first time . . In the 19th century he used the detailed sketch of Mars to determine the rotation speed of the planet. In 1665 he was appointed professor of geometry at Gresham University. In Micrographia (1665; "small drawing"), he discussed the possibility of manufacturing artificial fibers in the same way as silkworm spinning, including studies and illustrations on the crystal structure of snowflakes, first using corks I named it. His research on microscopic honeycomb cavity microscopic fossils made him one of the first advocates of evolution.

He measured using gravity of the pendulum (1666) to measure gravity and proposed to try to prove that the earth and the moon follows an elliptical path around the sun. In 1672, he found a diffraction phenomenon (a bend around the corner); to explain it, he proposed the lightwave theory. In 1678 he described the inverse square law to describe planetary motion, the rule Newton used in a modified form later. Hook complained that he was not completely able to obtain legal trust and was involved in intense controversy with Newton. The hook is the first person to explain in general that all material expands when heated and air is composed of particles that are far away from each other.

Calling Dr. Robert Hook as a genius is too small to explain such a person. Robert Hook was born on the Isle of Wight on July 28, 1635. When he was a child, he was so ill that he could not attend school for a long time. Therefore, his idea depends greatly on prejudiced learning and prosperity. Robert likes painting, his bed has a brush and a pencil, and his imagination is released. He spent a lot of time off school and began to draw incredibly detailed figures. His father, the pastor, was fascinated by his work of art, especially the work of the new clock mechanism he claimed.

Robert Hook and the British scientist were born in 1635 and died in 1703. Robert Hook was born in the freshwater town of Writing Island. Hook was born as Minister named John Hook. Robert received a lot of education, and these education was not done in the class. He studied at a portrait painter Sir Peter Lely (young). He is educated at Oxford University. After graduating from college, he was an assistant to Robert Boyle. He made an experimental curator of the Royal Society 1662, and the secretary was 1677-88. In Hooke's law, Hook is known for his elasticity theory. In 1665, Hook became professor of geometry at Gresham University until his death. Despite being a famous scientist, Hook does not have a surviving portrait.

In 1655 Boyle moved to Oxford where he told that the Royal Society was founded in 1660 and joined the invisible academy - a group of natural philosophers. Boyle hired Robert Hook to help the experiment around this time. They both fabricated an air pump used in many of Boyle 's most important experiments, including the need to measure combustion air, animal breathing and sound transmission. Boyle also proves the inverse relationship between gas volume and pressure in science textbooks around the world like Boyle's law.
