Robert Hooke, a renowned physicist, discovered the law of elasticity and contributed significantly to the study of stress and balance springs in watches. He was a member of the Royal Society of London and had diverse interests, including astronomy, crystallography, and biology. Hooke made significant contributions to the understanding of Mars' rotation, snowflake structures, and coined the term 'cells' for microscopic structures. He also studied light, discovering diffraction, and proposed that matter expands when heated.
