Question

Robert Hooke’s observations were published in
A)Zerographia
B)Micrographia
C)Biographia
D)None of these

Answer 1

Hint: Robert Hooke, born July 18, 1635 was an English physicist who discovered the law of elasticity, referred to as Hooke’s law, and who did research in a very remarkable sort of field.

Complete answer:
One amongst the primary men to make a Gregorian reflector, Hooke discovered the fifth star within the Trapezium, an asterism within the constellation Orion, in 1664 and first suggested that Jupiter rotates on its axis.

His detailed sketches of Mars were employed in the 19th century to work out that planet’s rate of rotation. In Micrographia (“Small Drawings”) he included his studies and illustrations of the crystal structure of snowflakes, discussed the likelihood of producing artificial fibres by a process like spinning of silkworm, and first used the word cell to call microscopic honeycomb cavities in cork. His studies of microscopic fossils led him to become one amongst the primary proponents of a theory of evolution.

Hooke's reputation within the history of biology largely rests on his book Micrographia, published in 1665. Hooke devised the light microscope and illumination system shown above, one amongst the most effective such microscopes of his time, and used it in his demonstrations at the Royal Society's meetings.

Hence, the correct answer is option (B)

Note: He suggested that the force of gravity can be measured by utilizing the motion of a pendulum (1666) and attempted to indicate that Earth and therefore the Moon follow an elliptical path around the Sun. In 1672 he discovered the phenomenon of diffraction; to clarify it, he offered a wave theory of light. He stated the inverse square law to explain planetary motions in 1678, a law that Newton later utilized in modified form. Hooke complained that he wasn't given sufficient credit for the law and has become involved in bitter controversy with Newton. Hooke was the primary man to state normally that everyone's matter expands when heated which air is formed of particles separated from one another by relatively large distances.
