|Hooke (hk) Pronunciation Key
English physicist, inventor, and mathematician who contributed to many aspects of science. With Robert Boyle he demonstrated that both combustion and respiration require air and that sound does not travel in a vacuum. Hooke studied plants and other objects under microscopes and was the first to use the word cell to describe the patterns he observed. He also identified fossils as a record of changes among organisms on the planet throughout history.
