Jensen's theory of intelligence proposes that individual differences in intelligence are largely due to genetic factors, whereas Galton's early work laid the foundation for research into the heritability of intelligence. Both theories focus on the role of genetics in shaping intelligence, with Jensen's theory building on Galton's ideas by incorporating more modern genetic research methods.
The person most closely related to the theory of gravitation is Sir Isaac Newton. He formulated the law of universal gravitation in the 17th century, which describes the gravitational attraction between masses. Newton's work laid the foundation for classical mechanics and significantly advanced our understanding of how objects interact in space. His principles were later refined by Albert Einstein's theory of general relativity in the early 20th century.
